  • Communicating with a remote host via HTTPS

    - by user619818
    I have developed a solution where a Java applet makes a socket connection to a port on a socket server (which happens to run on a web server). But a new client has implemented https within their LAN and so I am told communication must be via HTTPS. With standard socket communication you connect to a port on a host. But the clients HTTPS uses port 443. So will it be possible to connect to a socket server using a different port? I assume it must be possible? Any help would be much appreciated.

  • Enable remote VNC from the commandline?

    - by Stefan Lasiewski
    I have one computer running Ubuntu 10.04, and is running Vino, the default VNC server. I have a second Windows box which is running a VNC client, but does not have any X11 capabilities. I am ssh'd into the Ubuntu host from the Windows host, but I forgot to enable VNC access on the Ubuntu host. On the Ubuntu host, is there a way for me to enable VNC connections from the Ubuntu commandline? Update: As @koanhead says below, there is no man page for vino (e.g. man -k vino and info vino return nothing), and vino --help doesn't show any help).

  • Aus 2 mach 1: Oracle Audit Vault and Database Firewall

    - by Heinz-Wilhelm Fabry (DBA Community)
    Gestern hat Oracle bekanntgegeben, dass die beiden Produkte Oracle Audit Vault und Oracle Database Firewall zu einem Produkt werden. Der neue Produktname wird "Oracle Audit Vault and Database Firewall" sein. Software und Dokumentation werden in den nächsten Tagen zum Download verfügbar sein. Das Zusammenlegen macht durchaus Sinn, denn die ursprünglichen Produkte wiesen im Bereich der Protokollierung und des Berichtswesens deutliche Überschneidungen auf. Damit lag es nahe, die Repositories für das Speichern des Protokolls zu vereinheitlichen. Endlich wird es im Bereich Auditing durch die Einführung eines Development Kits auch möglich sein, Systeme anzubinden, für die Oracle keine vorgefertigten Konnektoren / Kollektoren liefert. Mit der Zusammenlegung verbunden ist ein völlig neues Lizenzierungsmodell, das zu deutlichen Kostensenkungen für kleinere und mittlere Installationen führt.

  • Move SQL Server transaction log to another disk

    - by Jim Lahman
    When restoring a database backup, by default, SQL Server places the database files in the master database file directory.  In this example, that location is in L:\MSSQL10.CHTL\MSSQL\DATA as shown by the issuance of sp_helpfile   Hence, the restored files for the database CHTL_L2_DB are in the same directory     Per SQL Server best practices, the log file should be on its own disk drive so that the database and log file can operate in a sequential manner and perform optimally. The steps to move the log file is as follows: Record the location of the database files and the transaction log files Note the future destination of the transaction log file Get exclusive access to the database Detach from the database Move the log file to the new location Attach to the database Verify new location of transaction log Record the location of the database file To view the current location of the database files, use the system stored procedure, sp_helpfile 1: use chtl_l2_db 2: go 3:   4: sp_helpfile 5: go   Note the future destination of the transaction log file The future destination of the transaction log file will be located in K:\MSSQLLog   Get exclusive access to the database To get exclusive access to the database, alter the database access to single_user.  If users are still connected to the database, remove them by using with rollback immediate option.  Note:  If you had a pane connected to the database when the it is placed into single_user mode, then you will be presented with a reconnection dialog box. 1: alter database chtl_l2_db 2: set single_user with rollback immediate 3: go Detach from the database   Now detach from the database so that we can use windows explorer to move the transaction log file 1: use master 2: go 3:   4: sp_detach_db 'chtl_l2_db' 5: go   After copying the transaction log file re-attach to the database 1: use master 2: go 3:   4: sp_attach_db 'chtl_l2_db', 5: 'L:\MSSQL10.CHTL\MSSQL\DATA\CHTL_L2_DB.MDF', 6: 'K:\MSSQLLog\CHTL_L2_DB_4.LDF', 7: 'L:\MSSQL10.CHTL\MSSQL\DATA\CHTL_L2_DB_1.NDF', 8: 'L:\MSSQL10.CHTL\MSSQL\DATA\CHTL_L2_DB_2.NDF', 9: 'L:\MSSQL10.CHTL\MSSQL\DATA\CHTL_L2_DB_3.NDF' 10: GO

  • Mount drive on remote machine

    - by NikolaiDante
    My current set up is: I have my main machine (Darkseid) upstairs which has a drive with all my films on it, which I don't keep mounted. Downstairs, next to the tv, I have a htpc (Archangel) which has xbmc installed on it, which points to a samba share on the main machine. Everything works fine when the drive is mounted, but is there a script I can write to send a command to the upstairs machine from the downstairs machine to mount the drive to save the walk upstairs? #lazy Both machines are Ubuntu 12.04

  • open source database project

    - by Jeff V
    What is the best way to build an open source database? I would like to build a database of all vehicles and the related maintenance information (i.e Oil Weight, Quantity, Tire Pressure, Windshield wipers etc). Currently this information is fragmented or just not put on line in an open way. Once collection began I would want to import into a DB and then be able to distribute freely. Is there a process (site or group) that I can start gathering this information in a reliable and verifiable way? Is there any issues that I should watch out for?

    It has been a while since I last posted a utility query, and today, to avoid other work I am supposed to be doing, I decided to go ahead and work on another post.  Today, I went ahead and worked on a server configuration type query. One query I find I use pretty often is the following one that lists the files in the database. In this blog I will include 3 queries.  The first will deal with files and databases, and the second runs in a database to see the files and their filegroups (If there...(read more)

  • Login sometimes failing immediately after restoring a database

    - by Ian Ringrose
    We have a set of automated tests that restore a database then run some .net code against the database. Sometimes after the database is restored the login from Ado.net fails. If I re-run the test, then the restore and login works OK. The restored database looks OK when viewed with Management Studio. This is only an problem on some machines. We are using SQL server 2008. Is there a known issue with a database restore “returning “ a very short time before the restored database is up and running.

  • Microsoft Sql Server 2008 R2 System Databases

    For a majority of software developers little time is spent understanding the inner workings of the database management systems (DBMS) they use to store data for their applications.  I personally place myself in this grouping. In my case, I have used various versions of Microsoft’s SQL Server (2000, 2005, and 2008 R2) and just recently learned how valuable they really are when I was preparing to deliver a lecture on "SQL Server 2008 R2, System Databases". Microsoft Sql Server 2008 R2 System DatabasesSo what are system databases in MS SQL Server, and why should I know them? Microsoft uses system databases to support the SQL Server DBMS, much like a developer uses config files or database tables to support an application. These system databases individually provide specific functionality that allows MS SQL Server to function. Name Database File Log File Master master.mdf mastlog.ldf Resource mssqlsystemresource.mdf mssqlsystemresource.ldf Model model.mdf modellog.ldf MSDB msdbdata.mdf msdblog.ldf Distribution distmdl.mdf distmdl.ldf TempDB tempdb.mdf templog.ldf Master DatabaseIf you have used MS SQL Server then you should recognize the Master database especially if you used the SQL Server Management Studio (SSMS) to connect to a user created database. MS SQL Server requires the Master database in order for DBMS to start due to the information that it stores. Examples of data stored in the Master database User Logins Linked Servers Configuration information Information on User Databases Resource DatabaseHonestly, until recently I never knew this database even existed until I started to research SQL Server system databases. The reason for this is due largely to the fact that the resource database is hidden to users. In fact, the database files are stored within the Binn folder instead of the standard MS SQL Server database folder path. This database contains all system objects that can be accessed by all other databases.  In short, this database contains all system views and store procedures that appear in all other user databases regarding system information. One of the many benefits to storing system views and store procedures in a single hidden database is the fact it improves upgrading a SQL Server database; not to mention that maintenance is decreased since only one code base has to be mainlined for all of the system views and procedures. Model DatabaseThe Model database as the name implies is the model for all new databases created by users. This allows for predefining default database objects for all new databases within a MS SQL Server instance. For example, if every database created by a user needs to have an “Audit” table when it is  created then defining the “Audit” table in the model will guarantees that the table will be located in every new database create after the model is altered. MSDB DatabaseThe MSDBdatabase is used by SQL Server Agent, SQL Server Database Mail, SQL Server Service Broker, along with SQL Server. The SQL Server Agent uses this database to store job configurations and SQL job schedules along with SQL Alerts, and Operators. In addition, this database also stores all SQL job parameters along with each job’s execution history.  Finally, this database is also used to store database backup and maintenance plans as well as details pertaining to SQL Log shipping if it is being used. Distribution DatabaseThe Distribution database is only used during replication and stores meta data and history information pertaining to the act of replication data. Furthermore, when transactional replication is used this database also stores information regarding each transaction. It is important to note that replication is not turned on by default in MS SQL Server and that the distribution database is hidden from SSMS. Tempdb DatabaseThe Tempdb as the name implies is used to store temporary data and data objects. Examples of this include temp tables and temp store procedures. It is important to note that when using this database all data and data objects are cleared from this database when SQL Server restarts. This database is also used by SQL Server when it is performing some internal operations. Typically, SQL Server uses this database for the purpose of large sort and index operations. Finally, this database is used to store row versions if row versioning or snapsot isolation transactions are being used by SQL Server. Additionally, I would love to hear from others about their experiences using system databases, tables, and objects in a real world environments.

  • How does datomic handle "corrections"?

    - by blueberryfields
    tl;dr Rich Hickey describes datomic as a system which implicitly deals with timestamps associated with data storage from my experience, data is often imperfectly stored in systems, and on many occasions needs to retroactively be corrected (ie, often the question of "was a True on Tuesday at 12:00pm?" will have an incorrect answer stored in the database) This seems like a spot where the abstractions behind datomic might break - do they? If they don't, how does the system handle such corrections? Rich Hickey, in several of his talks, justifies the creation of datomic, and explains its benefits. His work, if I understand correctly, is motivated by core the insight that humans, when speaking about data and facts, implicitly associate some of the related context into their work(a date-time). By pushing the work required to manage the implicit date-time component of context into the database, he's created a system which is both much easier to understand, and much easier to program. This turns out to be relevant to most database programmers in practice - his work saves everyone a lot of time managing complex, hard to produce/debug/fix, time queries. However, especially in large databases, data is often damaged/incorrect (maybe it was not input correctly, maybe it eroded over time, etc...). While most database updates are insertions of new facts, and should indeed be treated that way, a non-trivial subset of the work required to manage time-queries has to do with retroactive updates. I have yet to see any documentation which explains how such corrections, or retroactive updates, are handled by datomic; from my experience, they are a non-trivial (and incredibly difficult to deal with) subset of time-related data manipulation that database programmers are faced with. Does datomic gracefully handle such updates? If so, how?

  • Best Method/Library For Remote Authentication

    - by Mike
    I have a web app that has a REST API interface: http://api.example.com/core that uses API Keys and domain specific keys (key has to be used on the specified domain). I then will have several client sites with ajax forms where we will require users to sign in before being able to submit the form. This form will add data to a table, and submit an email to several recipients along with checking credentials. This form will use an ajax submit to our REST API. All Communication to/from the API is over SSL Ideal Flow: Visitor Fills Form Out -> Enters User/pass -> Submits Form -> ajax request to REST API -> API Verifies credentials -> does CRUD -> sends emails -> returns 200/403 -> perform DOM manipulation based on return code in ajax call Are there any libraries in PHP that currently do something to this similarly? Would OAuth be a good use for this scenario? Languages used are: js/html/css/php/MySQL

  • Two different websites in one remote hosting

    - by Kor
    My client asked me that a website that is hosted in one server (and pointing there through a domain) should also be accessed (into a specific directory) from another domain, which is not pointing there. For example: http://www.foo.com, hosted at GoDaddy, with the full website http://www.bar.com, hosted at Bluehost, needs to access http://www.foo.com/bar, as if it was the http://www.bar.com's root. So, if anybody enters through http://www.bar.com, it should internally load http://www.foo.com/bar, without visually changing the url. I amb not sure if this is possible using .htaccess or anything like this. Could anybody show me some light? Thanks in advance

  • How do I (robustly) remotely execute tasks on Windows workstations in a domain?

    - by Zac B
    I'm not even sure if "robustly" is a word. Anyway. Context: We have a few hundred Windows 7 workstations on a LAN. We use AD/GPO management pretty heavily, but there are a lot of periodic and/or manual maintenance tasks we need to do that can't be done via GPO/scheduled task. For example, say I want to execute program X (which runs silently, in the background, and doesn't bother the user) on workstation Y, or say I want to execute task A on a workstation group B either on a schedule or on demand. Kicking the users off of their computers to do this (i.e. using RDP) is a no-no, and doesn't work on groups anyway. Question: What's the best way to do this that is robust enough that, after setup, I could give it to beginner support people (read: people who are phobic of the command line, and get confused with GUI interfaces more complicated than Firefox)? I'm a competent programmer, and, if there is a robust set of tools or framework out there for this type of task, I'd consider hacking something together myself if it didn't take too long. If there's some combination of tools or techniques that others use to make remote-workstation-administration doable by beginners, I have yet to find it. For those who care about the "why": I'm midlevel IT, and was told to implement a remote management solution that allows arbitrary/scheduled remote execution, with confirmation that programs actually ran remotely, and the ability to view what they returned. "Why?" I asked, "Can't I just use PsExec and the task scheduler on a dispatcher machine?" "No," I was told, "'Joe' the second-week tech is going to be in charge of this one, and he needs something simple with a GUI." What I've tried: I've played with making a bunch of one-clickable "transfer files to remote computer and run them with PsExec" batch/VB scrips, but those tend to break down and don't easily support running on customizable groups. I've played a little bit with the Windows version of Puppet, but it doesn't support arbitrary-time remote execution (it's ability to group computers into a tree/node structure is really nice though). I've used an older version of Altiris, and, while it does a lot of what I want, it's interface is awful, it's slow, crashes a lot, and is probably too expensive for management. SwiftWater's DMS solution does some of what I want, but it's very underdeveloped, closed-source (not a deal breaker but not ideal), and I get the impression that support and reliability are lacking.
