• How to Use RDA to Generate WLS Thread Dumps At Specified Intervals?

  - by Daniel Mortimer

  Introduction There are many ways to generate a thread dump of a WebLogic Managed Server. For example, take a look at: Taking Thread Dumps - [an excellent blog post on the Middleware Magic site]or  Different ways to take thread dumps in WebLogic Server (Document 1098691.1) There is another method - use Remote Diagnostic Agent! The solution described below is not documented, but it is relatively straightforward to execute. One advantage of using RDA to collect the thread dumps is RDA will also collect configuration, log files, network, system, performance information at the same time. Instructions 1. Not familiar with Remote Diagnostic Agent? Take a look at my previous blog "Resolve SRs Faster Using RDA - Find the Right Profile" 2. Choose a profile, which includes the WebLogic Server data collection modules (for example the profile "WebLogicServer"). At RDA setup time you should see the prompt below: ------------------------------------------------------------------------------- S301WLS: Collects Oracle WebLogic Server Information ------------------------------------------------------------------------------- Enter the location of the directory where the domains to analyze are located (For example in UNIX, <BEA Home>/user_projects/domains or <Middleware Home>/user_projects/domains) Hit 'Return' to accept the default (/oracle/11AS/Middleware/user_projects/domains) > For a successful WLS connection, ensure that the domain Admin Server is up and running. Data Collection Type:   1  Collect for a single server (offline mode)   2  Collect for a single server (using WLS connection)   3  Collect for multiple servers (using WLS connection) Enter the item number Hit 'Return' to accept the default (1) > 2 Choose option 2 or 3. Note: Collect for a single server or multiple servers using WLS connection means that RDA will attempt to connect to execute online WLST commands against the targeted server(s). The thread dumps are collected using the WLST function - "threadDumps()". If WLST cannot connect to the managed server, RDA will proceed to collect other data and ignore the request to collect thread dumps. If in the final output you see no Thread Dump menu item, then it's likely that the managed server is in a state which prevents new connections to it. If faced with this scenario, you would have to employ alternative methods for collecting thread dumps. 3. The RDA setup will create a setup.cfg file in the RDA_HOME directory. Open this file in an editor. You will find the following parameters which govern the number of thread dumps and thread dump interval. #N.Number of thread dumps to capture WREQ_THREAD_DUMP=10 #N.Thread dump interval WREQ_THREAD_DUMP_INTERVAL=5000 The example lines above show the default settings. In other words, RDA will collect 10 thread dumps at 5000 millisecond (5 second) intervals. You may want to change this to something like: #N.Number of thread dumps to capture WREQ_THREAD_DUMP=10 #N.Thread dump interval WREQ_THREAD_DUMP_INTERVAL=30000 However, bear in mind, that such change will increase the total amount of time it takes for RDA to complete its run. 4. Once you are happy with the setup.cfg, run RDA. RDA will collect, render, generate and package all files in the output directory. 5. For ease of viewing, open up the RDA Start html file - "xxxx__start.htm". The thread dumps can be found under the WLST Collections for the target managed server(s). See screenshots belowScreenshot 1:RDA Start Page - Main Index Screenshot 2: Managed Server Sub Index Screenshot 3: WLST Collections Screenshot 4: Thread Dump Page - List of dump file links Screenshot 5: Thread Dump Dat File Link Additional Comment: A) You can view the thread dump files within the RDA Start Page framework, but most likely you will want to download the dat files for in-depth analysis via thread dump analysis tools such as: Thread Dump Analyzer -  Samurai - a GUI based tail , thread dump analysis tool If you are new to thread dump analysis - take a look at this recorded Support Advisor Webcast  Oracle WebLogic Server: Diagnosing Performance Issues through Java Thread Dumps[Slidedeck from webcast in PDF format]B) I have logged a couple of enhancement requests for the RDA Development Team to consider: Add timestamp to dump file links, dat filename and at the top of the body of the dat file Package the individual thread dumps in a zip so all dump files can be conveniently downloaded in one go.

• Computer Networks UNISA - Chap 15 &ndash; Network Management

  - by MarkPearl

  After reading this section you should be able to Understand network management and the importance of documentation, baseline measurements, policies, and regulations to assess and maintain a network’s health. Manage a network’s performance using SNMP-based network management software, system and event logs, and traffic-shaping techniques Identify the reasons for and elements of an asset managements system Plan and follow regular hardware and software maintenance routines Fundamentals of Network Management Network management refers to the assessment, monitoring, and maintenance of all aspects of a network including checking for hardware faults, ensuring high QoS, maintaining records of network assets, etc. Scope of network management differs depending on the size and requirements of the network. All sub topics of network management share the goals of enhancing the efficiency and performance while preventing costly downtime or loss. Documentation The way documentation is stored may vary, but to adequately manage a network one should at least record the following… Physical topology (types of LAN and WAN topologies – ring, star, hybrid) Access method (does it use Ethernet 802.3, token ring, etc.) Protocols Devices (Switches, routers, etc) Operating Systems Applications Configurations (What version of operating system and config files for serve / client software) Baseline Measurements A baseline is a report of the network’s current state of operation. Baseline measurements might include the utilization rate for your network backbone, number of users logged on per day, etc. Baseline measurements allow you to compare future performance increases or decreases caused by network changes or events with past network performance. Obtaining baseline measurements is the only way to know for certain whether a pattern of usage has changed, or whether a network upgrade has made a difference. There are various tools available for measuring baseline performance on a network. Policies, Procedures, and Regulations Following rules helps limit chaos, confusion, and possibly downtime. The following policies and procedures and regulations make for sound network management. Media installations and management (includes designing physical layout of cable, etc.) Network addressing policies (includes choosing and applying a an addressing scheme) Resource sharing and naming conventions (includes rules for logon ID’s) Security related policies Troubleshooting procedures Backup and disaster recovery procedures In addition to internal policies, a network manager must consider external regulatory rules. Fault and Performance Management After documenting every aspect of your network and following policies and best practices, you are ready to asses you networks status on an on going basis. This process includes both performance management and fault management. Network Management Software To accomplish both fault and performance management, organizations often use enterprise-wide network management software. There various software packages that do this, each collect data from multiple networked devices at regular intervals, in a process called polling. Each managed device runs a network management agent. So as not to affect the performance of a device while collecting information, agents do not demand significant processing resources. The definition of a managed devices and their data are collected in a MIB (Management Information Base). Agents communicate information about managed devices via any of several application layer protocols. On modern networks most agents use SNMP which is part of the TCP/IP suite and typically runs over UDP on port 161. Because of the flexibility and sophisticated network management applications are a challenge to configure and fine-tune. One needs to be careful to only collect relevant information and not cause performance issues (i.e. pinging a device every 5 seconds can be a problem with thousands of devices). MRTG (Multi Router Traffic Grapher) is a simple command line utility that uses SNMP to poll devices and collects data in a log file. MRTG can be used with Windows, UNIX and Linux. System and Event Logs Virtually every condition recognized by an operating system can be recorded. This is typically done using event logs. In Windows there is a GUI event log viewer. Similar information is recorded in UNIX and Linux in a system log. Much of the information collected in event logs and syslog files does not point to a problem, even if it is marked with a warning so it is important to filter your logs appropriately to reduce the noise. Traffic Shaping When a network must handle high volumes of network traffic, users benefit from performance management technique called traffic shaping. Traffic shaping involves manipulating certain characteristics of packets, data streams, or connections to manage the type and amount of traffic traversing a network or interface at any moment. Its goals are to assure timely delivery of the most important traffic while offering the best possible performance for all users. Several types of traffic prioritization exist including prioritizing traffic according to any of the following characteristics… Protocol IP address User group DiffServr VLAN tag in a Data Link layer frame Service or application Caching In addition to traffic shaping, a network or host might use caching to improve performance. Caching is the local storage of frequently needed files that would otherwise be obtained from an external source. By keeping files close to the requester, caching allows the user to access those files quickly. The most common type of caching is Web caching, in which Web pages are stored locally. To an ISP, caching is much more than just convenience. It prevents a significant volume of WAN traffic, thus improving performance and saving money. Asset Management Another key component in managing networks is identifying and tracking its hardware. This is called asset management. The first step to asset management is to take an inventory of each node on the network. You will also want to keep records of every piece of software purchased by your organization. Asset management simplifies maintaining and upgrading the network chiefly because you know what the system includes. In addition, asset management provides network administrators with information about the costs and benefits of certain types of hardware or software. Change Management Networks are always in a stage of flux with various aspects including… Software changes and patches Client Upgrades Shared Application Upgrades NOS Upgrades Hardware and Physical Plant Changes Cabling Upgrades Backbone Upgrades For a detailed explanation on each of these read the textbook (Page 750 – 761)

• Using Windows Previous Versions to access ZFS Snapshots (July 14, 2009)

  - by user12612012

  The Previous Versions tab on the Windows desktop provides a straightforward, intuitive way for users to view or recover files from ZFS snapshots.  ZFS snapshots are read-only, point-in-time instances of a ZFS dataset, based on the same copy-on-write transactional model used throughout ZFS.  ZFS snapshots can be used to recover deleted files or previous versions of files and they are space efficient because unchanged data is shared between the file system and its snapshots.  Snapshots are available locally via the .zfs/snapshot directory and remotely via Previous Versions on the Windows desktop. Shadow Copies for Shared Folders was introduced with Windows Server 2003 but subsequently renamed to Previous Versions with the release of Windows Vista and Windows Server 2008.  Windows shadow copies, or snapshots, are based on the Volume Snapshot Service (VSS) and, as the [Shared Folders part of the] name implies, are accessible to clients via SMB shares, which is good news when using the Solaris CIFS Service.  And the nice thing is that no additional configuration is required - it "just works". On Windows clients, snapshots are accessible via the Previous Versions tab in Windows Explorer using the Shadow Copy client, which is available by default on Windows XP SP2 and later.  For Windows 2000 and pre-SP2 Windows XP, the client software is available for download from Microsoft: Shadow Copies for Shared Folders Client. Assuming that we already have a shared ZFS dataset, we can create ZFS snapshots and view them from a Windows client. zfs snapshot tank/home/administrator@snap101zfs snapshot tank/home/administrator@snap102 To view the snapshots on Windows, map the dataset on the client then right click on a folder or file and select Previous Versions.  Note that Windows will only display previous versions of objects that differ from the originals.  So you may have to modify files after creating a snapshot in order to see previous versions of those files. The screenshot above shows various snapshots in the Previous Versions window, created at different times.  On the left panel, the .zfs folder is visible, illustrating that this is a ZFS share.  The .zfs setting can be toggled as desired, it makes no difference when using previous versions.  To make the .zfs folder visible: zfs set snapdir=visible tank/home/administrator To hide the .zfs folder: zfs set snapdir=hidden tank/home/administrator The following screenshot shows the Previous Versions panel when a file has been selected.  In this case the user is prompted to view, copy or restore the file from one of the available snapshots. As can be seen from the screenshots above, the Previous Versions window doesn't display snapshot names: snapshots are listed by snapshot creation time, sorted in time order from most recent to oldest.  There's nothing we can do about this, it's the way that the interface works.  Perhaps one point of note, to avoid confusion, is that the ZFS snapshot creation time isnot the same as the root directory creation timestamp. In ZFS, all object attributes in the original dataset are preserved when a snapshot is taken, including the creation time of the root directory.  Thus the root directory creation timestamp is the time that the directory was created in the original dataset. # ls -d% all /home/administrator         timestamp: atime         Mar 19 15:40:23 2009         timestamp: ctime         Mar 19 15:40:58 2009         timestamp: mtime         Mar 19 15:40:58 2009         timestamp: crtime         Mar 19 15:18:34 2009 # ls -d% all /home/administrator/.zfs/snapshot/snap101         timestamp: atime         Mar 19 15:40:23 2009         timestamp: ctime         Mar 19 15:40:58 2009         timestamp: mtime         Mar 19 15:40:58 2009         timestamp: crtime         Mar 19 15:18:34 2009 The snapshot creation time can be obtained using the zfs command as shown below. # zfs get all tank/home/administrator@snap101NAME                             PROPERTY  VALUEtank/home/administrator@snap101  type      snapshottank/home/administrator@snap101  creation  Mon Mar 23 18:21 2009 In this example, the dataset was created on March 19th and the snapshot was created on March 23rd. In conclusion, Shadow Copies for Shared Folders provides a straightforward way for users to view or recover files from ZFS snapshots.  The Windows desktop provides an easy to use, intuitive GUI and no configuration is required to use or access previous versions of files or folders.

• How to handle updated configuration when it's already been cloned for editing

  - by alexrussell

  Really sorry about the title that probably doesn't make much sense. Hopefully I can explain myself better here as it's something that's kinda bugged me for ages, and is now becoming a pressing concern as I write a bit of software with configuration. Most software comes with default configuration options stored in the app itself, and then there's a configuration file (let's say) that a user can edit. Once created/edited for the first time, subsequent updates to the application can not (easily) modify this configuration file for fear of clobbering the user's own changes to the default configuration. So my question is, if my application adds a new configurable parameter, what's the best way to aid discoverability of the setting and allow the user (developer) to override it as nicely as possible given the following constraints: I actually don't have a canonical default config in the application per se, it's more of a 'cascading filesystem'-like affair - the config template is stored in default/config.json and when the user wishes to edit the configuration, it's copied to user/config.json. If a user config is found it is used - there is no automatic overriding of a subset of keys, the whole new file is used and that's that. If there's no user config the default config is used. When a user wishes to edit the config they run a command to 'generate' it for them (which simply copies the config.json file from the default to the user directory). There is no UI for the configuration options as it's not appropriate to the userbase (think of my software as a library or something, the users are developers, the config is done in the user/config.json file). Due to my software being library-like there's no simple way to, on updating of the software, run some tasks automatically (so any ideas of look at the current config, compare to template config, add ing missing keys) aren't appropriate. The only solution I can think of right now is to say "there's a new config setting X" in release notes, but this doesn't seem ideal to me. If you want any more information let me know. The above specifics are not actually 100% true to my situation, but they represent the problem equally well with lower complexity. If you do want specifics, however, I can explain the exact setup. Further clarification of the type of configuration I mean: think of the Atom code editor. There appears to be a default 'template' config file somewhere, but as soon as a configuration option is edited ~/.atom/config.cson is generated and the setting goes in there. From now on is Atom is updated and gets a new configuration key, this file cannot be overwritten by Atom without a lot of effort to ensure that the addition/modification of the key does not clobber. In Atom's case, because there is a GUI for editing settings, they can get away with just adding the UI for the new setting into the UI to aid 'discoverability' of the new setting. I don't have that luxury. Clarification of my constraints and what I'm actually looking for: The software I'm writing is actually a package for a larger system. This larger system is what provides the configuration, and the way it works is kinda fixed - I just do a config('some.key') kinda call and it knows to look to see if the user has a config clone and if so use it, otherwise use the default config which is part of my package. Now, while I could make my application edit the user's configuration files (there is a convention about where they're stored), it's generally not done, so I'd like to live with the constraints of the system I'm using if possible. And it's not just about discoverability either, one large concern is that the addition of a configuration key won't actually work as soon as the user has their own copy of the original template. Adding the key to the template won't make a difference as that file is never read. As such, I think this is actually quite a big flaw in the design of the configuration cascading system and thus needs to be taken up with my upstream. So, thinking about it, based on my constraints, I don't think there's going to be a good solution save for either editing the user's configuration or using a new config file every time there are updates to the default configuration. Even the release notes idea from above isn't doable as, if the user does not follow the advice, suddenly I have a config key with no value (user-defined or default). So the new question is this: what is the general way to solve the problem of having a default configuration in template config files and allowing a user to make user-specific version of these in order to override the defaults? A per-key cascade (rather than per-file cascade) where the user only specifies their overrides? In this case, what happens if a configuration value is an array - do we replace or append to the default (or, more realistically, how does the user specify whether they wish to replace or append to)? It seems like configuration is kinda hard, so how is it solved in the wild?

• UppercuT v1.0 and 1.1&ndash;Linux (Mono), Multi-targeting, SemVer, Nitriq and Obfuscation, oh my!

  - by Robz / Fervent Coder

  Recently UppercuT (UC) quietly released version 1 (in August). I’m pretty happy with where we are, although I think it’s a few months later than I originally planned. I’m glad I held it back, it gave me some more time to think about some things a little more and also the opportunity to receive a patch for running builds with UC on Linux. We also released v1.1 very recently (December). UppercuT v1 Builds On Linux Perhaps the most significant changes to UC going v1 is that it now supports builds on Linux using Mono! This is thanks mostly to Svein Ackenhausen for the patches and working with me on getting it all working while not breaking the windows builds!  This means you can use mono on Windows or Linux. Notice the shell files to execute with Linux that come as part of UC now. Multi-Targeting Perhaps one of the hardest things to do that requires an automated build is multi-targeting. At v1 this is early, and possibly prone to some issues, but available.  We believe in making everything stupid simple, so it’s as simple as adding a comma to the microsoft.framework property. i.e. “net-3.5, net-4.0” to suddenly produce both framework builds. When you build, this is what you get (if you meet each framework’s requirements): At this time you have to let UC override the build location (as it does by default) or this will not work.  Semantic Versioning By now many of you have been using UppercuT for awhile and have watched how we have done versioning. Many of you who use git already know we put the revision hash in the informational/product version as the last octet. At v1, UppercuT has adopted the semantic versioning scheme. What does that mean? This is a short read, but a good one: http://SemVer.org SemVer (Semantic Versioning) is really using versioning what it was meant for. You have three octets. Major.Minor.Patch as in 1.1.0.  UC will use three different versioning concepts, one for the assembly version, one for the file version, and one for the product version. All versions - The first three octects of the version are owned by SemVer. Major.Minor.Patch i.e.: 1.1.0 Assembly Version - The assembly version would much closer follow SemVer. Last digit is always 0. Major.Minor.Patch.0 i.e: 1.1.0.0 File Version - The file version occupies the build number as the last digit. Major.Minor.Patch.Build i.e.: 1.1.0.2650 Product/Informational Version - The last octect of your product/informational version is the source control revision/hash. Major.Minor.Patch.RevisionOrHash i.e. (TFS/SVN): 1.1.0.235 i.e. (Git/HG): 1.1.0.a45ace4346adef0 SemVer is not on by default, the passive versioning scheme is still in effect. Notice that version.use_semanticversioning has been added to the UppercuT.config file (and version.patch in support of the third octet): Gems Support Gems support was added at v1. This will probably be deprecated as some point once there is an announced sunset for Nu v1. Application gems may keep it around since there is no alternative for that yet though (CoApp would be a possible replacement). Nitriq Support Nitriq is a code analysis tool like NDepend. It’s built by Mr. Jon von Gillern. It uses LINQ query language, so you can use a familiar idiom when analyzing your code base. It’s a pretty awesome tool that has a free version for those looking to do code analysis! To use Nitriq with UC, you are going to need the console edition.  To take advantage of Nitriq, you just need to update the location of Nitriq in the config: Then add the nitriq project files at the root of your source. Please refer to the Nitriq documentation on how these are created. UppercuT v1.1 Obfuscation One thing I started looking into was an easy way to obfuscate my code. I came across EazFuscator, which is both free and awesome. Plus the GUI for it is super simple to use. How do you make obfuscation even easier? Make it a convention and a configurable property in the UC config file! And the code gets obfuscated! Closing Definitely get out and look at the new release. It contains lots of chocolaty (sp?) goodness. And remember, the upgrade path is almost as simple as drag and drop!

• A very useful custom component

  - by Kevin Smith

  Whenever I am debugging a problem in WebCenter Content (WCC) I often find it useful to see the contents of the internal data binder used by WCC when executing a service. I want to know the value of all parameters passed in by the caller, either a user in the web GUI or from an application calling the service via RIDC or web services. I also want to the know the value of binder variables calculated by WCC as it processes a service. What defaults has it applied based on configuration settings or profile rules? What values has it derived based on the user input? To help with this I created a  component that uses a java filter to dump out the contents of the internal data binder to the WCC trace file. It dumps the binder contents using the toString() method. You can register this filter code using many different filter hooks to see how the binder is updated as WCC processes the service. By default, it uses the validateStandard filter hook which is useful during a CHECKIN service. It uses the system trace section, so make sure that trace section is enabled before looking for the output from this component. Here is some sample output>system/6    10.09 09:57:40.648    IdcServer-1    filter: postParseDataForServiceRequest, binder start -- system/6    10.09 09:57:40.698    IdcServer-1    *** LocalData *** system/6    10.09 09:57:40.698    IdcServer-1    (10 keys + 0 defaults) system/6    10.09 09:57:40.698    IdcServer-1    ClientEncoding=UTF-8 system/6    10.09 09:57:40.698    IdcServer-1    IdcService=CHECKIN_UNIVERSAL system/6    10.09 09:57:40.698    IdcServer-1    NoHttpHeaders=0 system/6    10.09 09:57:40.698    IdcServer-1    UserDateFormat=iso8601 system/6    10.09 09:57:40.698    IdcServer-1    UserTimeZone=UTC system/6    10.09 09:57:40.698    IdcServer-1    dDocTitle=Check in from RIDC using Framework Folder system/6    10.09 09:57:40.698    IdcServer-1    dDocType=Document system/6    10.09 09:57:40.698    IdcServer-1    dSecurityGroup=Public system/6    10.09 09:57:40.698    IdcServer-1    parentFolderPath=/folder1/folder2 system/6    10.09 09:57:40.698    IdcServer-1    primaryFile=testfile5.bin     system/6    10.09 09:57:40.698    IdcServer-1    ***  RESULT SETS  ***>system/6    10.09 09:57:40.698    IdcServer-1    binder end -------------------------------------------- See the readme included in the component for more details.

• Using EUSM to manage EUS mappings in OUD

  - by Sylvain Duloutre

  EUSM is a command line tool that can be used to manage the EUS settings starting with the 11.1 release of Oracle. In the 11.1 release the tool is not yet documented in the Oracle EUS documentation, but this is planned for a coming release. The same commands used by EUSM can be performed from the Database Console GUI or from Grid Control*. For more details, search for the document ID 1085065.1 on OTN. The examples below don't include all the EUSM options, only the options that are used by EUS. EUSM is user friendly and intuitive. Typing eusm help <option> lists the parameters to be used for any of the available options. Here are the options related to connectivity with OUD : ldap_host="gnb.fr.oracle.com" - name of the OUD server. ldap_port=1389 - nonSSL (SASL) port used for OUD connections.  ldap_user_dn="cn=directory manager" - OUD administrator nameldap_user_password="welcome1" - OUD administrator password Find below common commands: To List Enterprise roles in OUD eusm listEnterpriseRoles domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud administrator> ldap_user_password=<oud admin password> To List Mappings eusm listMappings domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud admin> ldap_user_password=<oud admin password> To List Enterprise Role Info eusm listEnterpriseRoleInfo enterprise_role=<rdn of enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create Enterprise Role eusm createRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create User-Schema Mapping eusm createMapping database_name=<SID of target database> realm_dn="<realm>" map_type=<ENTRY/SUBTREE> map_dn="<dn of enterprise user>" schema="<name of the shared schema>" ldap_host=<oud hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password="<oud admin password>" To Create Proxy Permission eusm createProxyPerm proxy_permission=<Name of the proxypermission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Grant Proxy permission to Proxy group eusm grantProxyPerm proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<password> group_dn="<dn of the enterprise group>" To Map proxy permission to proxy user in DB eusm addTargetUser proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> database_name=<SID of the target database> target_user=<target database user> dbuser=<Database user with DBA privileges> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> Enterprise role to Global role mapping eusm addGlobalRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn="<realm>" database_name=<SID of the target database> global_role=<name of the global role defined in the target database> dbuser=<database user> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> ldap_host=<oid_hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password>

• Value cannot be null, ArgumentNullException

  - by Wooolie

  I am currently trying to return an array which contains information about a seat at a theate such as Seat number, Name, Price and Status. I am using a combobox where I want to list all vacant or reserved seats based upon choice. When I choose reserved seats in my combobox, I call upon a method using AddRange.

• Clone a VirtualBox Machine

  I just installed VirtualBox, which I want to try out based on recommendations from peers for running a server from within my Windows 7 x64 OS.  Ive never used VirtualBox, so Im certainly no expert at it, but I did want to share my experience with it thus far.  Specifically, my intention is to create a couple of virtual machines.  One I intend to use as a build server, for which a virtual machine makes sense because I can easily move it around as needed if there are hardware issues (its worth noting my need for setting up a build server at the moment is a result of a disk failure on the old build server).  The other VM I want to set up will act as a proxy server for the issue tracking system were using at Code Project, Axosoft OnTime.  They have a Remote Server application for this purpose, and since the OnTime install is 300 miles away from my location, the Remote Server should speed up my use of the OnTime client by limiting the chattiness with the database (at least, thats the hope). So, I need two VMs, and Im lazy.  I dont want to have to install the OS and such twice.  No problem, it should be simple to clone a virtualbox machine, or clone a virtualbox hard drive, right?  Well unfortunately, if you look at the UI for VirtualBox, theres no such command.  Youre left wondering How do I clone a VirtualBox machine? or the slightly related How do I clone a VirtualBox hard drive? If youve used VirtualPC, then you know that its actually pretty easy to copy and move around those VMs.  Not quite so easy with VirtualBox.  Finding the files is easy, theyre located in your user folder within the .VirtualBox folder (possibly within a HardDisks folder).  The disks have a .vdi extension and will be pretty large if youve installed anything.  The one shown here has just Windows Server 2008 R2 installed on it nothing else. If you copy the .vdi file and rename it, you can use the Virtual Media Manager to view it and you can create a new machine and choose the new drive to attach to.  Unfortunately, if you simply make a copy of the drive, this wont work and youll get an error that says something to the effect of: Cannot register the hard disk PATH with UUID {id goes here} because a hard disk PATH2 with UUID {same id goes here} already exists in the media registry (PATH to XML file). There are command line tools you can use to do this in a way that avoids this error.  Specifically, the c:\Program File\Sun\VirtualBox\VBoxManage.exe program is used for all command line access to VirtualBox, and to copy a virtual disk (.vdi file) you would call something like this: VBoxManage clonehd Disk1.vdi Disk1_Copy.vdi However, in my case this didnt work.  I got basically the same error I showed above, along with some debug information for line 628 of VBoxManageDisk.cpp.  As my main task was not to debug the C++ code used to write VirtualBox, I continued looking for a simple way to clone a virtual drive.  I found it in this blog post. The Secret setvdiuuid Command VBoxManage has a whole bunch of commands you can use with it just pass it /? to see the list.  However, it also has a special command called internalcommands that opens up access to even more commands.  The one thats interesting for us here is the setvdiuuid command.  By calling this command and passing in the file path to your vdi file, it will reset the UUID to a new (random, apparently) UUID.  This then allows the virtual media manager to cope with the file, and lets you set up new machines that reference the newly UUIDd virtual drive.  The full command line would be: VBoxManage internalcommands setvdiuuid MyCopy.vdi The following screenshot shows the error when trying clonehd as well as the successful use of setvdiuuid. Summary Now that I can clone machines easily, its a simple matter to set up base builds of any OS I might need, and then fork from there as needed.  Hopefully the GUI for VirtualBox will be improved to include better support for copying machines/disks, as this is Im sure a very common scenario. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Visual View for Schema Based Editor

  - by Geertjan

  Starting from yesterday's blog entry, make the following change in the DataObject's constructor: registerEditor("text/x-sample+xml", true); I.e., the MultiDataObject.registerEditor method turns the editor into a multiview component. Now, again, within the DataObject, add the following, to register a source editor in the multiview component: @MultiViewElement.Registration(         displayName = "#LBL_Sample_Source",         mimeType = "text/x-sample+xml",         persistenceType = TopComponent.PERSISTENCE_NEVER,         preferredID = "ShipOrderSourceView",         position = 1000) @NbBundle.Messages({     "LBL_Sample_Source=Source" }) public static MultiViewElement createEditor(Lookup lkp){     return new MultiViewEditorElement(lkp); } Result: Next, let's create a visual editor in the multiview component. This could be within the same module as the above or within a completely separate module. That makes it possible for external contributors to provide modules with new editors in an existing multiview component: @MultiViewElement.Registration(displayName = "#LBL_Sample_Visual", mimeType = "text/x-sample+xml", persistenceType = TopComponent.PERSISTENCE_NEVER, preferredID = "VisualEditorComponent", position = 500) @NbBundle.Messages({ "LBL_Sample_Visual=Visual" }) public class VisualEditorComponent extends JPanel implements MultiViewElement {     public VisualEditorComponent() {         initComponents();     }     @Override     public String getName() {         return "VisualEditorComponent";     }     @Override     public JComponent getVisualRepresentation() {         return this;     }     @Override     public JComponent getToolbarRepresentation() {         return new JToolBar();     }     @Override     public Action[] getActions() {         return new Action[0];     }     @Override     public Lookup getLookup() {         return Lookup.EMPTY;     }     @Override     public void componentOpened() {     }     @Override     public void componentClosed() {     }     @Override     public void componentShowing() {     }     @Override     public void componentHidden() {     }     @Override     public void componentActivated() {     }     @Override     public void componentDeactivated() {     }     @Override     public UndoRedo getUndoRedo() {         return UndoRedo.NONE;     }     @Override     public void setMultiViewCallback(MultiViewElementCallback callback) {     }     @Override     public CloseOperationState canCloseElement() {         return CloseOperationState.STATE_OK;     } } Result: Next, the DataObject is automatically returned from the Lookup of DataObject. Therefore, you can go back to your visual editor, add a LookupListener, listen for DataObjects, parse the underlying XML file, and display values in GUI components within the visual editor.

• MVVM/Presentation Model With WinForms

  - by Erik Ashepa

  Hi, I'm currently working on a brownfield application, it's written with winforms, as a preparation to use WPF in a later version, out team plans to at least use the MVVM/Presentation model, and bind it against winforms... I've explored the subject, including the posts in this site (which i love very much), when boiled down, the main advantage of wpf are : binding controls to properties in xaml. binding commands to command objects in the viewmodel. the first feature is easy to implement (in code), or with a generic control binder, which binds all the controls in the form. the second feature is a little harder to implement, but if you inherit from all your controls and add a command property (which is triggered by an internal event such as click), which is binded to a command instance in the ViewModel. The challenges I'm currently aware of are : implementing a commandmanager, (which will trigger the CanInvoke method of the commands as necessery. winforms only supports one level of databinding : datasource, datamember, wpf is much more flexible. am i missing any other major features that winforms lacks in comparison with wpf, when attempting to implement this design pattern? i sure many of you will recommend some sort of MVP pattern, but MVVM/Presentation model is the way to go for me, because I'll want future WPF support. Thanks in advance, Erik.

• Core Data migration problem: "Persistent store migration failed, missing source managed object model

  - by John Gallagher

  The Background A Cocoa Non Document Core Data project with two Managed Object Models. Model 1 stays the same. Model 2 has changed, so I want to migrate the store. I've created a new version by Design Data Model Add Model Version in Xcode. The difference between versions is a single relationship that's been changed from to a one to many. I've made my changes to the model, then saved. I've made a new Mapping Model that has the old model as a source and new model as a destination. I've ensured all Mapping Models and Data Models and are being compiled and all are copied to the Resource folder of my app bundle. I've switched on migrations by passing in a dictionary with the NSMigratePersistentStoresAutomaticallyOption key as [NSNumber numberWithBool:YES] when adding the Persistent Store. Rather than merging all models in the bundle, I've specified the two models I want to use (model 1 and the new version of model 2) and merged them using modelByMergingModels: The Problem No matter what I do to migrate, I get the error message: "Persistent store migration failed, missing source managed object model." What I've Tried I clean after every single build. I've tried various combinations of having only the model I'm migrating to in Resources, being compiled, or both. Since the error message implies it can't find the source model for my migration, I've tried having every version of the model in both the Resources folder and being compiled. I've made sure I'm not making a really basic error by switching back to the original version of my data model. The app runs fine. I've deleted the Mapping Model and the new version of the model, cleaned, then recreated both. I've tried making a different change in the new model - deleting an entity instead. I'm at my wits end. I can't help but think I've made a huge mistake somewhere that I'm not seeing. Any ideas?

• bind a WPF datagrid to a datatable

  - by Jim Thomas

  I have used the marvelous example posted at: http://www.codeproject.com/KB/WPF/WPFDataGridExamples.aspx to bind a WPF datagrid to a datatable. The source code below compiles fine; it even runs and displays the contents of the InfoWork datatable in the wpf datagrid. Hooray! But the WPF page with the datagrid will not display in the designer. I get an incomprehensible error instead on my design page which is shown at the end of this posting. I assume the designer is having some difficulty instantiating the dataview for display in the grid. How can I fix that? XAML Code: xmlns:local="clr-namespace:InfoSeeker" <Window.Resources> <ObjectDataProvider x:Key="InfoWorkData" ObjectType="{x:Type local:InfoWorkData}" /> <ObjectDataProvider x:Key="InfoWork" ObjectInstance="{StaticResource InfoWorkData}" MethodName="GetInfoWork" /> </Window.Resources> <my:DataGrid DataContext="{Binding Source={StaticResource InfoWork}}" AutoGenerateColumns="True" ItemsSource="{Binding}" Name="dataGrid1" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" /> C# Code: namespace InfoSeeker { public class InfoWorkData { private InfoTableAdapters.InfoWorkTableAdapter infoAdapter; private Info infoDS; public InfoWorkData() { infoDS = new Info(); infoAdapter = new InfoTableAdapters.InfoWorkTableAdapter(); infoAdapter.Fill(infoDS.InfoWork); } public DataView GetInfoWork() { return infoDS.InfoWork.DefaultView; } } } Error shown in place of the designer page which has the grid on it: An unhandled exception has occurred: Type 'MS.Internal.Permissions.UserInitiatedNavigationPermission' in Assembly 'PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable. at System.Runtime.Serialization.FormatterServices.InternalGetSerializableMembers(RuntimeType type) at System.Runtime.Serialization.FormatterServices.GetSerializableMembers(Type type, StreamingContext context) at System.Runtime.Serialization.Formatters.Binary.WriteObjectInfo.InitMemberInfo() at System.Runtime.Serialization.Formatters.Binary.WriteObjectInfo.InitSerialize(Object obj, ISurrogateSelector surrogateSelector, StreamingContext context, SerObjectInfoInit serObjectInfoInit, IFormatterConverter converter, ObjectWriter objectWriter) ...At:Ms.Internal.Designer.DesignerPane.LoadDesignerView()

• What good technology podcasts are out there?

  - by Michael Stum

  Yes, Podcasts, those nice little Audiobooks I can listen to on the way to work. With the current amount of Podcasts, it's like searching a needle in a haystack, except that the haystack happens to be the Internet and is filled with too many of these "Hot new Gadgets" stuff :( Now, even though I am mainly a .NET developer nowadays, maybe anyone knows some good Podcasts from people regarding the whole software lifecycle? Unit Testing, Continous Integration, Documentation, Deployment... So - what are you guys and gals listening to? Please note that the categorizations are somewhat subjective and may not be 100% accurate as many podcasts cover several areas. Categorization is made against what is considered the "main" area.

• WPF application with MS Access database as a data source

  - by Kay Zed

  I have a Microsoft Access 2010 database. Now, using Visual Studio 2010, I want to create a WPF application and add the database as a data source. The app will have a window with a frame that provides navigation through pages. No problem so far. But: -What is the right way to set up the database in this scenario? Tables only? Or must everything go via queries? (VS2010 talks about views which I assume (?) are queries) -Database data must be updatable and records can be added. Some relationships go through link tables (many-to-many) and there are nullable foreign key relationships. Must I take manual steps to make it work? -While adding the data source VS2010 created an xsd from my Access database. I think the xsd might need further tweaking for the application to work the right way. What if I change my Access database design, I'd have to regenerate the xsd again as well. Is this right, and is it the way it is usually done? OR, should I let the original Access database go and give the application the capability to create new empty databases? -How do you provide controls in a page to step through the records in a table? Is there a special database control? -What is the way (WPF class?) to load records into the data context that displays in a page? (At this level it probably does not matter what type of data source it is.)

• Entity Framework with MySQL - Timeout Expired while Generating Model

  - by Nathan Taylor

  I've constructed a database in MySQL and I am attempting to map it out with Entity Framework, but I start running into "GenerateSSDLException"s whenever I try to add more than about 20 tables to the EF context. An exception of type 'Microsoft.Data.Entity.Design.VisualStudio.ModelWizard.Engine.ModelBuilderEngine+GenerateSSDLException' occurred while attempting to update from the database. The exception message is: 'An error occurred while executing the command definition. See the inner exception for details.' Fatal error encountered during command execution. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. There's nothing special about the affected tables, and it's never the same table(s), it's just that after a certain (unspecific) number of tables have been added, the context can no longer be updated without the "Timeout expired" error. Sometimes it's only one table left over, and sometimes it's three; results are pretty unpredictable. Furthermore, the variance in the number of tables which can be added before the error indicates to me that perhaps the problem lies in the size of the query being generated to update the context which includes both the existing table definitions, and also the new tables that are being added to it. Essentially, the SQL query is getting too large and it's failing to execute for some reason. If I generate the model with EdmGen2 it works without any errors, but the generated EDMX file cannot be updated within Visual Studio without producing the aforementioned exception. In all likelihood the source of this problem lies in the tool within Visual Studio given that EdmGen2 works fine, but I'm hoping that perhaps others could offer some advice on how to approach this very unique issue, because it seems like I'm not the only person experiencing it. One suggestion a colleague offered was maintaining two separate EBMX files with some table crossover, but that seems like a pretty ugly fix in my opinion. I suppose this is what I get for trying to use "new technology". :(

• close long poll connection, jQuery-ajax

  - by MyGGaN

  Background I use a Tornado-like server with support for long-polls. Each web pages a user clicks around to sets up a long poll to the server like this: $.ajax({ type: 'GET', url: "/mylongpollurl/", dataType: 'application/json', success: function(json) { // I do stuff here }, error: function(xhr, errText, ex) { // If timeout I send a new long-poll request } }); Problem I will now rely on data that I get from Fiddler monitoring all requests made from my browser (FF at the moment). Page 1 is loaded and the long poll request is made, now idling at server side. I click a link to page 2 and that page is loaded and setting up a long poll request, BUT the long poll request from page 1 is still idling at server side (according to Fiddler). This means that I will stack all long poll calls when clicking around the page, thus end up with lots of active connections on the server (or are they maybe sharing connection?) My thoughts - As it's a Tornado-like server (using epoll) it can handle quite a lot of connections. But this fact is not to exploit in my opinion. What I mean is that I prefer not to have a timeout on the server for this case (were the client disappears). - I know those stand alone pages better uses a common head and only swap content via ajax calls but this design we use today was not my call... - The best way to solve this would probably be to have the connection reused (hard to pull off I think) or closed as soon as the browser leaves the page (you click to another page). Thanks -- MyGGaN

• Visual Studio 2010 is asking to convert RDLC created on VS2008 to RDLC 2008 format?

  - by Junior Mayhé

  I've created my project on Visual Studio 2008, as well RDLC files on it. But now, when I open the solution on Visual Studio 2010 and want to open RDLC file, it's showing me a warning. That's a little funny. The report was created on VS2008 and VS2010 is asking to convert to 2008 format. Perhaps there was a problem on my VS2008 installation that created RDLC files using some ancient format (2005??!) The problem is, when you confirm with Ok button, do some design ajustments and run the app, it throws an error on 'Main report': ex.InnerException {"The definition of the report 'Main Report' is invalid."} [Microsoft.Reporting.DefinitionInvalidException]: {"The definition of the report 'Main Report' is invalid."} Data: {System.Collections.ListDictionaryInternal} HelpLink: null InnerException: {"The report definition is not valid.

• QT: trouble with qobject_cast

  - by weevilo

  I have derived QGraphicsItem and QGraphicsScene classes. I want the items to be able to call scene() and get a derviedGraphicsItem * instead of a QGraphicsItem *, so I reimplemented QGraphicsScene::itemAt to return a derived pointer. DerivedItem* DerivedScene::itemAt( const QPointF &position, const QTransform &dt ) const { return qobject_cast< DerivedItem * >( QGraphicsScene::itemAt(position, dt) ); } I get the following error (Qt 4.6, GCC 4.4.3 on Ubuntut 10.4) scene.cpp: In member function ‘DerivedItem* DerivedScene::itemAt(qreal, qreal, const QTransform&) const’: scene.cpp:28: error: no matching function for call to ‘qobject_cast(QGraphicsItem*)’ I then noticed QGraphicsItem doesn't inherit QObject, so I made my derived QGraphicsItem class have multiple inheritance from QObject and QGraphicsItem, and after adding the Q_OBJECT macro and rebuilding the project I get the same error. Am I going about this the wrong way? I know it's supposed to be bad design to try to cast a parent class as a child, but in this case it seems like what I want, since my derived item class has new functionality and its objects need a way to call that new functionality on items around themselves, and asking the items scene object with itemAt() seems like the best way - but I need itemAt() to return a pointer of the right type. I can get around this by having the derived items cast the QGraphicsItem * returned by QGraphicsScene::itemAt() using dynamic_cast, but I don't really understand why that works and not qobject_cast, or the benefits or disadvantages to using dynamic_cast vs. qobject_cast.

• How do I solve column width problems in a SSRS Tablix?

  - by David Stein

  I'm creating a simple report from Microsoft Dynamics CRM. When I pull in the following dataset: SELECT FQD.productidname , FQD.NEW_PRICEBREAKS , FQD.NEW_WEEKSARO , ltrim(rtrim(FP.NEW_PRODUCTNAME)) AS NewProductDesc , FQD.productdescription , FQD.quoteid , FQD.quantity , FQD.productiddsc , FQD.baseamount , FQD.lineitemnumber , FQD.priceperunit , FQD.extendedamount , ISNULL(FP.productnumber, '') AS productnumber , ISNULL(FQD.uomidname, '-') AS Unit , FQD.tax AS Tax , FQD.volumediscountamount * FQD.quantity AS Discount , FQD.manualdiscountamount AS MDiscount , FQD.quotedetailid , FQD.crm_moneyformatstring , FQD.NEW_PRICEPERUNIT , FQD.NEW_PRICEPERUNIT_BASE FROM FilteredQuoteDetail FQD LEFT OUTER JOIN FilteredProduct FP ON FQD.productid = FP.productid WHERE (FQD.quoteid = @CRM_QuoteId) The NewProductDesc field is too wide. If I shorted it in design view, it still comes out too wide in the presentation. I think the field is coming out that wide because the database field probably has a bunch of blank spaces at the end of every description. I could not find a way to force that field in the Tablix not to grow horizontally, so I attempted to remedy it in the dataset by replacing the NewProductDesc line with: ltrim(rtrim(FP.NEW_PRODUCTNAME)) AS NewProductDesc However, that has no effect either. Can anyone suggest why this behavior is occuring? Can anyone tell me how I can force the field not to grow horizontally?

• Selectively suppress XML Code Comments in C#?

  - by Mike Post

  We deliver a number of assemblies to external customers, but not all of the public APIs are officially supported. For example, due to less than optimal design choices sometimes a type must be publicly exposed from an assembly for the rest of our code to work, but we don't want customers to use that type. One part of communicating the lack of support is not provide any intellisense in the form of XML comments. Is there a way to selectively suppress XML comments? I'm looking for something other than ignoring warning 1591 since it's a long term maintenance issue. Example: I have an assembly with public classes A and B. A is officially supported and should have XML documentation. B is not intended for external use and should not be documented. I could turn on XML documentation and then suppress warning 1591. But when I later add the officially supported class C, I want the compiler to tell me that I've screwed up and failed to add the XML documentation. This wouldn't occur if I had suppressed 1591 at the project level. I suppose I could #pragma across entire classes, but it seems like there should be a better way to do this.

• Forcing UIInterfaceOrientation changes on iPhone

  - by Andiih

  I'm strugging with getting an iPhone application which requires just about every push or pop in the Nav Controller Stack to change orientation. Basically the first view is portrait, the second landscape the third portrait again (Yes I know this is less than ideal, but that's the design and I've got to implement it). I've been through various advice on here.... http://stackoverflow.com/questions/995723/how-do-i-detect-a-rotation-on-the-iphone-without-the-device-autorotating http://stackoverflow.com/questions/1824682/force-portrait-orientation-on-pushing-new-view-to-uinavigationviewcontroller http://stackoverflow.com/questions/181780/is-there-a-documented-way-to-set-the-iphone-orientation But without total success. Setting to link against 3.1.2 my reading of the linked articles above seems to indicate that if my portrait view pushes a view with - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return ((interfaceOrientation == UIInterfaceOrientationLandscapeRight) ); } Then then that view should appear rotated to landscape. What happens is it appears in its "broken" portrait form, then rotates correctly as the device is turned. If I pop the controller back to my portrait view (which has an appropriate shouldAutoRotate...) then that remains in broken landscape view until the device is returned to portrait orientation. I've also tried removing all the shouldautorotate messages, and instead forcing rotation by transforming the view. This kind of works, and I've figured out that by moving the status bar (which is actually hidden in my application) [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight; the keyboard will appear with the correct orientation when desired. The problem with this approach is that the status bar transform is weird and ugly when you don't have a status bar - a shadow looms over the page with each change. So. What am I missing. 1) Am I wrong in thinking that in 3.1.2 (or possibly earlier) shouldAutorotateToInterfaceOrientation should provide the desired orientation simply by pushing controllers ? 2) Is there another way of getting keyboards to appear in the correct orientation. 3) Are the undocumented API calls the way to go (please no!)

• AndroMDA maven code generation and JPA Annotations

  - by ArsenioM

  I am using the AndroMDA plugin for maven to generate code from an uml diagram made in MagicDraw. When the code is generated, AndroMDA desings the JPA annotation for the persitence layer. I think that at the compilation process AndroMDA uses Naming Strategies to determine the Table and Column names for the DataBase. I want to determine how AndroMDA desings this JPA annotations, because I need to display this DataBase names based on the UML entity and atributtes names. I was regarding if there is an API of AndroMDA that I could use to do this by giving it the uml diagram. Or at least, to know the Naming Strategies used by AndroMDA to achive that. AndroMDA at the compilation process design the JPA annotations for the Entities, Attributes, etc that are written in my java classes under a series of rules that exist within the EJB3 cartridge of AndroMDA. (The further Database is created using those JPA annotations). I want to create a program that returns me the same Table and Attributes names wrote on the JPA annotations, by giving it the .xml file of the uml diagram of a project. I was hoping that I could take advantage of the EJB3 cartridge to generate those Tables and Attribute names with my program. One way could be using an API of AndroMDA that do this(if it exits), or at least, by implementing the same rules used by the EJB3 cartridge for that matter. To be more illustrative, For example: If in my uml model I have an Entity called “CompanyGroup”, AndroMDA would generate the following code for the class definition: @javax.persistence.Entity @javax.persistence.Table(name = "COMPANY_GR") Public class CompanyGroup implements java.io.Serializable, Comparable< CompanyGroup This is just an example (not a real case), but nevertheless, the way how AndroMDA do the translation from “CompanyGroup” to “COMPANY_GR” has to be specified somewhere. Hope this explanation is useful enough. Thanks.

• ExtJs - Set a fixed width in a center layout in a Panel

  - by Benjamin

  Hi all, Using ExtJs. I'm trying to design a main which is divided into three sub panels (a tree list, a grid and a panel). The way it works is that you have a tree list (west) with elements, you click on an element which populates the grid (center), then you click on an element in the grid and that generates the panel (west). My main panel containing the three other ones has been defined with a layout 'border'. Now the problem I face is that the center layout (the grid) has been defined in the code with a fixed width and the west panel as an auto width. But when the interface gets generated, the grid width is suddenly taking all the space in the interface instead of the west panel. The code looks like that: var exploits_details_panel = new Ext.Panel({ region: 'east', autoWidth: true, autoScroll: true, html: 'test' }); var exploit_commands = new Ext.grid.GridPanel({ store: new Ext.data.Store({ autoDestroy: true }), sortable: true, autoWidth: false, region: 'center', stripeRows: true, autoScroll: true, border: true, width: 225, columns: [ {header: 'command', width: 150, sortable: true}, {header: 'date', width: 70, sortable: true} ] }); var exploits_tree = new Ext.tree.TreePanel({ border: true, region: 'west', width: 200, useArrows: true, autoScroll: true, animate: true, containerScroll: true, rootVisible: false, root: {nodeType: 'async'}, dataUrl: '/ui/modules/select/exploits/tree', listeners: { 'click': function(node) { } } }); var exploits = new Ext.Panel({ id: 'beef-configuration-exploits', title: 'Auto-Exploit', region: 'center', split: true, autoScroll: true, layout: { type: 'border', padding: '5', align: 'left' }, items: [exploits_tree, exploit_commands, exploits_details_panel] }); Here 'var exploits' is my main panel containing the three other sub panels. The 'exploits_tree' is the tree list containing some elements. When you click on one of the elements the grid 'exploit_commands' gets populated and when you click in one of the populated elements, the 'exploits_details_panel' panel gets generated. How can I set a fixed width on 'exploit_commands'? Thanks for your time.
