• Fixed expired accounts in Oracle 11g

  - by Álvaro G. Vicario

  I have an Oracle 11g server that's used for PHP development. Recently, I had a problem logging into the Enterprise Manager due to expired passwords. I've already changed settings so passwords no longer expire and I've unlocked all users. However, the user manager shows most built-in users as expired. How can I fix that? (If I just set a password for each expired account I guess that whatever services are using it will no longer be able to log in.)

• Which smartphone OS would you choose for your users ?

  - by Florent

  While we currently only use windows mobile smartphone, my boss seems less and less reluctant to try and choose a new kind of OS for our users corporate phones. For some reasons, we can't use a Blackberry Enterprise Server, so i guess our only choice is between Iphone OS and Android (or Blackberry without BES ? I don't really know if this works fine) We need activesync capable smartphones of course, and activesync security policies must be available (pin when using your phone for example). Centralized Phone management would be nice too :D Any ideas on what should be the best smartphone to choose for our users ?

• Home-Router: Access internal server using external ip [migrated]

  - by user15863

  If I've got a typical home router -- say a Net Gear -- which has certain ports forwarded to a internal server, is there a way to tweak the router to let me access that internal server using the external IP address from within the same network? Is there a non-enterprise grade router that can handle this type of thing? In case that was strangely worded, let me re-phrase with an example. My external IP is 1.2.3.4. My internal server is 10.4.3.100 Port 1178 is being forwarded from the router to 10.4.3.100. I'd like to be able to be able to hit 10.4.3.100 from an internal ip of 10.4.3.10 by using the external ip of 1.2.3.4. Possible?

• Windows Disk I/O Analysis

  - by Jonathon

  It appears that we are having a problem with the disk i/o speed on our Windows 2003 Enterprise Edition server (64-bit). As we were initializing a database that created two 1G tablespaces on 3 different machines, it became obvious that the two smaller machines (each 32-bit Windows 2003 Standard Edition with less RAM) killed the larger machine when creating the files. The larger machine took 10x as long to create the tablespaces than did the other machines. Now, I am left wondering how that could be. What programs or scripts would you guys recommend for tracking down the I/O problem? I think the issue may be with the controller card (all boxes are hardware RAID 10, but have different controller cards), but I would like to check the actual disk I/O speed as well, so I have some hard numbers to work with. Any help would be appreciated.

• Product Recommendation: Good job scheduler for windows servers?

  - by Bret Fisher

  Looking for a mostly-GUI tool that is low cost (less then $1k, but not required) and allows you to create scheduled tasks and jobs without writing vbscript, batch files, or powershell. Something simple that speaks SMB/CIFS, SMTP, LDAP, etc. for such things as "delete some files based on a list of folders from this text file" or "disable all users with expired accounts" or "delete all disabled users not in this AD group". I've seen some of the big multi-OS enterprise task automation systems and they just look way overkill. We're a windows-only shop, Server 2003 or newer and there's got to be a simple non-agent based product that is drag-n-drop for some of this basic automation. Today we use all three languages mentioned above, and the scripts are not as reliable as a workflow-based-tool would be. Thanks.

• STOP: c000021a {Fatal System Error} The initial session process or system process terminated unexpectedly

  - by christof

  I'm encountering such an error after expanding disk space on a virtual machine using Hyper-V. STOP: c000021a {Fatal System Error} The initial session process or system process terminated unexpectedly with a status of (0x00000000) (0xc000012d 0x001003f0). The virtual server there is Windows Server 2008 R2 Enterprise Edition, which is also Domain Controller. I've tried to repair Windows but there is no restore point, and using the command line. I've tried the sfc /SCANNOW /OFFBOOTDIR /OFFWINDIR command, but I got the error Windows Resource Protection could not perform the requested operation.

• use of tcp_delack_min on redhat linux (kernel 2.6.18)

  - by user41466

  Hello, we're moving from Solaris to Redhat Linux, and trying to duplicate our low-latency setup, that, on solaris, includes the ndd settings related to TCP NO DELAY, and NAGLE ALGORITHM. I got the impression that those parameters are not all configurable system-wide, but still found some info. we have configured our applications to run with no nagle algorithm, but that is not sufficient. we have found an interesting RH article talking presenting the tcp_delack_min parameter, however, when browsing /proc/sys/net/ipv4/ , I can't find it there. would it be safe to assume that simply "adding" the parameter as it's said on the doc would be enough, or rather that the option is not supported by this version (would be strange, as RH specify that it "can be performed on a standard Red Hat Enterprise Linux installation") ? any other idea / recommendation to improve latency further ? thanks

• Install Mouse Driver on Windows 7 Professional 64 bit

  - by Soren

  I have a mouse that I absolutely love (been using them for years), A4Tech WOP-35. It has dual scrollers and 5 buttons, 3 of the buttons are programmable. I use them at work and at home. At work I am using Windows 7 Enterprise (32 bit), at home I am using Windows 7 Professional (64 bit). The drivers installed easily on my machine at work. Unfortunately, they will not install on my computer at home. When I double click on the Setup.exe, it asks me if I want to install it, and of course I click on "Yes", but nothing happens. When I say nothing happens, I mean nothing happens; it appears that it doesn't even try to install. The same thing happens when I right click on the setup.exe and select run as administrator. How can I get around this? I am guessing it is because I am running the 64 bit version of Windows.

• SQL Server 2008 update License

  - by Leo

  How can I change my SQL Server 2008 license? I have the Enterprise Edition installed with a 90-day key and it will expire on 7 days. Two months ago, I purchased the final one but I don't know how to install/change to the new one. Is there a legal way to do it or I have to uninstall completely the application and reinstall it with the new license? I don't want to do that because I already have setup some stuff on the current instance. Saludos, Leo

• Duplicate pseudo terminals in linux

  - by bobtheowl2

  On a redhat box [ Red Hat Enterprise Linux AS release 4 (Nahant Update 3) ] Frequently we notice two people being assigned to the same pseudo terminal. For example: $who am i user1 pts/4 Dec 29 08:38 (localhost:13.0) user2 pts/4 Dec 29 09:43 (199.xxx.xxx.xxx) $who -m user1 pts/4 Dec 29 08:38 (localhost:13.0) user2 pts/4 Dec 29 09:43 (199.xxx.xxx.xxx) $whoami user2 This causes problems in a script because "who am i" returns two rows. I know there are differences between the two commands, and obviously we can change the script to fix the problem. But it still bothers me that two users are being returned with the same terminal. We suspect it may be related to dead sessions. Can anyone explain why two (non-unique) pts number are being assigned and/or how that can be prevented in the future?

• Bitlocker and SQL Server (2012)

  - by cdonner

  I just turned on Bitlocker on my development laptop for the first time (Windows 8.1) and encrypted both SSDs. When I started SQL Server Enterprise Manager, it could not connect to the default instance on the local machine. Does this not work? I have been googling for an hour and only found anecdotal evidence, but no solid information. Just to clarify - I am not interested in encrypting a database. I want to run SQL Server on a machine with an encrypted drive.

• SQL Server 2008 Web edition in a hosting plan?

  - by Simon

  Do any hosting companies offer SQL Server 2008 Web edition in a hosting plan. GoDaddy for instance offers Standard/Enterprise editions which raise the price by $200 or so a month. I've tried a few hosting companies and can't find the web edition available. Why not? The web edition is supposed to be only $15/month - but I was hoping to be able to get this pricing through a dedicated server and not have to go off and separately get the licensing. I don't even know if its possible to buy just one copy!?

• SQL Server 2008 Replication Promotion

  - by Stefan Mai

  I have a 4 node cluster, 1 subscriber and 3 publishers, all running SQL Server 2008 R2 Enterprise. The intention is that if the subscriber goes down, we can use one of the publishers to quickly build up its replacement. Our testing reveals a problem though: the subcriber databases all have Not For Replication set to Yes on the identity columns so that they can maintain the identity set in the subscriber. This causes a problem when they become subscribers because now we don't have identity insert functionality: we get a primary key error. Any way to "promote" a subscriber to publisher?

• How to sync a folder on a remote computer to a server on a domain

  - by Pierre-Alain Vigeant

  We have a small remote office that often share data with us. I learned that the data is shared as a email attachment, but that obviously leads to versioning hell and overriding. I am looking for a way for then to synchronize a folder directly on our main office domain controller. I personally use LiveMesh, but I would like a tool that is synchronized to our server directly without a 3rd party hosting the data, since we already have an online backup service taking care of the offsite backup. What enterprise class tool would let us synchronize a folder from a remote computer that is out of our domain, into our the file server of our domain? The synchronization has to be two-way, e.g.: Someone from the remote office will create an invoice. Someone from our office will review it and make modification to it. The remote office need to see the change. Our server is on Windows 2003.

• SQL Server 2000 + ASP.NET: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'

  - by Rick

  I just migrated a development workstation FROM: Windows XP Pro SP3 with IIS 6 TO: Vista Enterprise 64bit with IIS 7 Since the move, one of my pages that accesses an SQL Server 2000 database is receiving the following error from my ASP.NET 2.0 web page: "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'." I have: enabled Windows Authentication in IIS and web.config disabled Anonymous Authentication in IIS set up Impersonation to run as the authenticated user verified that the logged in user (in this case, me) has access to the appropriate database on the SQL Server verified that my login and impersonation information is correct in the ASP.NET page by checking User.Identity.Name and System.Security.Principal.WindowsIdentity.GetCurrent().Name (both display my username) My connection string using SqlConnection is "Server={SERVER_NAME};Database={DB_NAME};Integrated Security=SSPI;Trusted_Connection=True;" Why is it trying to login with NT AUTHORITY\ANONYMOUS LOGIN? I have to assume it's some setting or web.config entry specific to IIS7 since it worked fine before the migration. NOTE: The SQL Server is Windows authentication only - no mixed mode or SQL only.

• Ubuntu server - Problem of routing

  - by Max

  Hi, I have setup a Ubuntu server with Ubuntu Enterprise Cloud. The server is connected to a private LAN with DHCP and Internet access (via a gateway). At first, the server was working fine. It can ping the internet. It can also ping other machine inside LAN. The problem happened after i let the machine idle for more than 1 hour. When I want to use the machine again, I can't ping the internet anymore. I can only ping the machine inside LAN. I try to ping the server from another machine and it's working. Then, i ssh into that server from another machine, and I found that I can ping the internet from that server. It seems that there are some problems in the routing table of this server. Can anyone help me on this? Thank you. Max

• is it right to call ejb bean from thread by ThreadPoolExecutor?

  - by kislo_metal

  I trying to call some ejb bean method from tread. and getting error : (as is glassfish v3) Log Level SEVERE Logger javax.enterprise.system.std.com.sun.enterprise.v3.services.impl Name-Value Pairs {_ThreadName=Thread-1, _ThreadID=42} Record Number 928 Message ID java.lang.NullPointerException at ua.co.rufous.server.broker.TempLicService.run(TempLicService.java Complete Message 35) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:637) here is tread public class TempLicService implements Runnable { String hash; //it`s Stateful bean @EJB private LicActivatorLocal lActivator; public TempLicService(String hash) { this.hash= hash; } @Override public void run() { lActivator.proccessActivation(hash); } } my ThreadPoolExecutor public class RequestThreadPoolExecutor extends ThreadPoolExecutor { private boolean isPaused; private ReentrantLock pauseLock = new ReentrantLock(); private Condition unpaused = pauseLock.newCondition(); private static RequestThreadPoolExecutor threadPool; private RequestThreadPoolExecutor() { super(1, Integer.MAX_VALUE, 10, TimeUnit.SECONDS, new LinkedBlockingQueue<Runnable>()); System.out.println("RequestThreadPoolExecutor created"); } public static RequestThreadPoolExecutor getInstance() { if (threadPool == null) threadPool = new RequestThreadPoolExecutor(); return threadPool; } public void runService(Runnable task) { threadPool.execute(task); } protected void beforeExecute(Thread t, Runnable r) { super.beforeExecute(t, r); pauseLock.lock(); try { while (isPaused) unpaused.await(); } catch (InterruptedException ie) { t.interrupt(); } finally { pauseLock.unlock(); } } public void pause() { pauseLock.lock(); try { isPaused = true; } finally { pauseLock.unlock(); } } public void resume() { pauseLock.lock(); try { isPaused = false; unpaused.signalAll(); } finally { pauseLock.unlock(); } } public void shutDown() { threadPool.shutdown(); } //<<<<<< creating thread here public void runByHash(String hash) { Runnable service = new TempLicService(hash); threadPool.runService(service); } } and method where i call it (it is gwt servlet, but there is no proble to call thread that not contain ejb) : @Override public Boolean submitHash(String hash) { System.out.println("submiting hash"); try { if (tBoxService.getTempLicStatus(hash) == 1) { //<<< here is the call RequestThreadPoolExecutor.getInstance().runByHash(hash); return true; } } catch (NoResultException e) { e.printStackTrace(); } return false; } I need to organize some pool of submitting hash to server (calls of LicActivator bean), is ThreadPoolExecutor design good idea and why it is not working in my case?

Thanks. << Answer: I am using DI (EJB 3.1) soo i do not need any look up here. (application packed in ear and both modules in it (web module and ejb), it works perfect for me). But I can use it only in managed classes. So.. 2.Can I use manual look up in Tread ? Could I use Bean that extends ThreadPoolExecutor and calling another bean that implements Runnable ? Or it is not allowed ?

• SharePoint Server Farm, what to do with an old server?

  - by tekiegreg

  Hi there, so we've procured a monster of a SQL Cluster and 4 screaming fast machines running the apps/WFE to start up our MOSS 2007 Enterprise Server farm, however I've got one server from the old server farm configuration that was just re-imaged and is still running decently, it's a 32 bit machine where the others are 64 bit machines so it really can't serve the same role as a 64 bit machine. I'd like to see if there's a role for it somewhere in the farm, a few thoughts: --Dedicated Search Query Server --Dedicated Excel Services Has anyone out there been in a similar situation? What did they do?

• How can I print a web page on a server?

  - by Gavin Schultz

  Suppose I develop a web page using the cool Google visualization API, and it does everything the user wants. They can the parameters, look at the graphs, and print the page to get a reasonable-looking report. All good. Now suppose I want to do the same thing server-side. For example, say we need a set of report generated at a specific time of day, printed to a PDF and emailed to a manager. It's not a user-initiated action, so we don't have a user's browser or their printer. We have a URL that would render the report if we had a browser, and that's it. Is there a good way to do this server-side? Is this just foolish? Has anyone done anything like that before? Do any of the major browsers have APIs that might provide such functionality? Keep in mind too that it's not just static HTML; probably javascript will be running first to shift the DOM around. I know we could implement a whole different reporting engine on the server side to do this, but that will (a) generate reports that look a bit different, and (b) require me to build/maintain two sets of functionality. Instead, I'd be happy if I could just render the page / pages I want in an invisible server-side browser and print it to a PDF (let's mostly ignore that step - I know any number of PDF printer drivers that could do this). I don't really want to do it ugly either - i.e. by starting a browser process and then sending keystrokes directly to the window either - that's just bound to fall apart with a slight nudge. The only related question I found had an answer like that. Any advice appreciated!

• Solaris to Linux conversion: Use VxFS or GFS?

  - by w00t

  We're a Solaris shop looking at RedHat Enterprise Linux and one of the things we're wondering is if we should keep Veritas Volume Manager + FileSystem or go with LVM+ext3 or RedHat's preferred cluster filesystem solution, GFS. One of the things we like about Veritas is that it can use Veritas Volume Replicator to have a remote copy of important filesystems. This functionality seems to be missing from RedHat, DRBD doesn't seem to be packaged in RHEL... So my questions are: Does anybody use VxFS/VxVM/VVR on Linux? Thoughts, experiences? Comparison with LVM+ext3? Anybody using GFS? Thoughts, experiences? Do you do remote replication for disaster recovery, and if so, how? Is there a standard RedHat way?

• wbadmin incremental system state backup

  - by user74513

  I am doing system state backups on a Windows Server 2008 R2 Enterprise (Service Pack 1) machine and expected the backups after the first one to be incremental. However with each backup a new directory with vhd files are created and the vhd files are almost the same size as the with the first backup. So the backups does not seem to be incremental. I used the following command to do the backup: wbadmin start systemstatebackup -backupTarget:f: I played around with the settings under "Configure Performance Settings" in the Windows Server Backup plugin in Server Manager but according to the description at the top of the dialog these settings are not applied to system state backups. Are there any settings available for wbadmin system state backup to make the backups incremental?

• Building a Data Warehouse

  - by Paul

  I've seen tutorials articles and posts on how to build datawarehouses with star and snowflakes schemas, denormalization of OLTP databases fact and dimension tables and so on. Also seen comments like: Star schemas are for datamarts, at best. There is absolutely no way a true enterprise data warehouse could be represented in a star schema, or snowflake either. I want to create a database that will server for reporting services and maybe (if that isn't enough) install analisys services and extract reports and data from cubes. My question was : Is it really necesarry to redesign my current database and follow the star/snowflake schemas with fact and dimension tables ? Thank you

• Matlab and MrVista

  - by AnnaRaven

  I'm new to MATLAB and mrVista. I'm running Matlab Version 7.8.0.347 (R2009a) 32-bit(win32) from February 12, 2009 OS is Windows 7 Professional I downloaded the most recent MrVista_hourly.zip and extracted it into my C:\Program_Files_(x86)\MATLAB directory. I think I need to run mrvInstall, but when I do, I get the following: EDU>> mrvInstall Checking VISATSOFT installation. Windows, 32-bit, installation Checking and possibly installing .NET framework. This can take several minutes Checking for visualization library (.dll) files. You are missing msvcp70.dll. So, I'm completely lost at this point. Do I just need to download msvcp70.dll from the net? If so, is there a safe place to download it from? If there's some other way I'm supposed to get mrVista to work from MATLAB, instead of mrvInstall, please let me know that. Thanks in advance for your help. EDIT: I've downloaded and installed the dll and still isn't working. I'll go ask on Super User. Thanks for trying to help anyway.

• How to deploy SQL Server 2005 Reporting Services on a network without a domain server?

  - by ti

  I have a small Windows network (~30 machines) and I need to deploy SQL Server 2005 Reporting Services. Because I use SQL Server Standard Edition and not Enterprise, I am forced to use Windows Authentication to the users. I am a Linux admin, and have near zero knowledge on Active Directory. As deep as my shallow knowledge goes, I think that I would need to invest in a domain server, a mirrored backup of that domain server. I think that I need to change every computer to use this domain too, and if the domain server goes down, every computer will be unavailable. Is there a easier way to deploy Windows Authentication so that users can access Reporting Services from their computers without changing the infra-structure that much? Thanks!
