• Where to install JDBC drivers in Hyperic Server

  - by Svish

  I have installed Hyperic Server 4.4.0 and I want to use an SQL plugin that connects to an Oracle database. To make this work on the Agent i had to download a JDBC driver for Oracle and put it in [agent-dir]/bundles/[bundle-dir]/pdk/lib. I can now run my plugin on the agent using java -jar hq-products.jar .... Now I want to add it so that it shows up in the server hq. I put the plugin in the appropriate directory and I can add it as a platform service. However, when i try to configure the plugin I get the following error: No suitable driver found for jdbc:oracle:thin:@blah.blah:blah:blah This is the same error I got on the client before I added the Oracle JDBC driver, so I assume that's the problem here too. But where do I put the JDBC drivers on the server?

• CentOS Vs Windows Server 2008

  - by Steve

  Hi, Apologies if the question appears ambiguous, I have little experience in this area and was after some informed opinions. I am deploying a test scenario of a server/client network and need to make some choices for Server. The client will be a Windows system as it meets the requirements for the client, the server choice has more room for selection. From my experience with Linux in general and the appealing nature of open source for low cost, security etc and the availability and performance of database and web server programs I have been considering CentOS as a server choice. I have the ability to make most of the choices of what software / server packages I wish to install. This includes Active Directory (something I have no experience with). How well does this operate with Windows clients? Am I being too selective and creating unnecessary complication by setting out not to use a Windows Server OS?

• How can I get a Windows 2008 print server to deploy to child domains?

  - by Tyler Benson

  I am setting up a print server for our company that has a parent domain and 2 child domains. The print server is on the parent domain and I have no problems getting the print server to deploy printers through group policy to users on its own domain. The problem I am having is that it isn't deploying the printers to users that are in it's child domains. Some other info that may help: I am not sharing or listing printers in the directory I have added pushprinterconnections.exe to the group policy login script Does anything come to mind?

• How to install java-1.7.0-openjdk-devel on RHEL Server 6.3?

  - by andand

  I have need of installing a Java 7 development environment on a RHEL 6.3 (system details are below). Following the official OpenJDK directions I tried yum install java-1.7.0-openjdk-devel (as root). This yields the error message: No package java-1.7.0-openjdk-devel available. The Java6 JDK java-1.6.0-openjdk-devel and the Java7 JRE java-1.7.0-openjdk are both available, but the Java7 JDK does not appear. Is there a non-default repository from which I can install this? If so what is it? Distribution: Red Hat Enterprise Linux Server release 6.3 (Santiago) Kernel: 2.6.32-279.5.2.el6.x86_64

• How to allow an internal server accept remote connections not through RD Gateway

  - by Matt Ahrens

  So, I help administrate a collection of servers running various windows server environments. We have a RD Gateway server, properly configured, to gatekeep for us. It does not have the other servers listed in it's server farm category, though. I just added a refurbished server for a non-profit development environment that is sharing the rack space and port. I would like this server to be accessible via remote connection, but not require RD gateway certification (I cannot add the users for this development server to our gateway since they do not work for the organization hosting the rack.) Is there any way for me to add this dev. server as an exception to which servers should require RD Gateway clearance, or otherwise let users bypass RD gateway credentials for this one machine? Thanks, and let me know if I am misinformed on how RD gateway works or anything. I am still learning.

• Windows Server Backup 2008 - Language Incompatibilities?

  - by Chris Walters

  I have 2 Windows 2008 Server R2 machines - one is Japanese language based and the other English. When I try to connect from the English language server using Windows Server Backup (snap-in) I get the following message: "An internal error has occurred in the backup engine or the computer that you are connected to remotely is running a version of backup application that is not compatible with the version on your local computer" Both claim to be running Version 1 of Windows Server Backup. Is remote connection to non-identical language server OSs a known problem? Specifically this is seen when attempting the "Connect To Another Server" in the action pane of Windows Server Backup.

• SQL Server 2005/2008 Licensing Decision

  - by Hakim

  Hello, I have purchased a dedicated server from a reputable Hosting company. They only have Windows Server 2008 OS installed on it and NO Sql server. Server Configuration is Intel Dual core Processor with 2GB of RAM and 100GB HDD. I wanted to host my web services on that server which will be using the MS SQL Server 2005 at the backend.There are multiple web services and each using a different Database. Microsoft has CAL basis Licensing , Which I understand is based on number of users accessing the database directly ( I may be wrong ) . But my users will be accessing the webservice and no direct connection to the database as such. Yes but the number of users accessing the web server cannot be known and is not under my control. Which Licensing is best suited for this kind of setup ? I don't need analysing and BI services right now ,but i may want to upgrade that in future may be. Any help will be appreciated. Thanks

• Ubuntu (desktop) server needed for school

  - by Dave Moody

  I need to build an ubuntu server for school, but I hate with a passion command line interfaces. I need a server with a desktop, like the current win server 2003 (which has crashed, ugh). This server needs to host the school lan domain, have an active directory, and handle the roaming profiles that the students and staff access through WinXP workstations. It also needs to work as a file server, maybe a print server. Can anyone advise me on how to create an Ubuntu server starting with Ubuntu Desktop edition? Much thanks if you respond... Dave.

• Micrsoft fax server not seeing new modem

  - by Tim Meers

  I recently added a new modem (a plain ol consumer grade one) to a fax server thats been up and running for years running on Microsoft Server 2003 fax services. The server currently has two modems, the new one is identical to one of the existing. After installing the new modem it showed up in the Fax Server Manager as a device but was not doing outbound faxes. (The server by default does not handle incoming.) So after a reboot the server no loger sees the modem in the Fax Server Manager but is listed as a device in device manager. I've attempted to restart just the fax service and even the whole box again but to no avail. Any one have any ideas on this one? Or any one with good links to resources for the fax service?

• Running Solr on VPS problem

  - by Camran

  I have a VPS with Ubuntu OS. I run solr om my local machine (windows xp laptop) just fine. I have configured Jetty, and Solr just the same way as on my computer, but on the server. I have also downloaded the JRE and installed it on the server. However, whenever I try to run the start.jar file, the PuTTY terminal shows a bunch of text but gets stuck. I could pase the text here but it is very long, so unless somebody wants to see it I wont. Also, I cant view the solr admin page at all. Does anybody have experience in this kind of problem? Maybe java isn't correctly installed? It is a VPS so maybe installation is different. Thanks UPDATE: These are the last lines from the terminal, in other words, this is where it stops every time: INFO: [] webapp=null path=null params={event=firstSearcher&q=static+firstSearcher+warming+query+from+solrconfig.xml} hits=0 status=0 QTime=9 May 28, 2010 8:58:42 PM org.apache.solr.core.QuerySenderListener newSearcher INFO: QuerySenderListener done.

• simple document server built over Apache HTTP server

  - by abhinav

  Hi, I want to build a simple document server. The requirement for now is : provide a hierarchical directory structure for placing documents (like pdfs, doc files) that is accessible through a browser, and provide the facility to search for documents by name and then be able to download them from server. Right now, placing documents can be done manually (directly place the files into some designated directory). I can do the hierarchical structure part of the problem by adding some configs to Apache's httpd.conf file. Basically I create a root directory for documents and then give an alias to this directory in httpd.conf file. That way, I can browse the directory structure in my browser and also download files placed there. I can provide more detail on this if needed. However, it is the searching documents by name part that I am not able to get to a clear solution yet. I have a few ideas like integrating Lucene with Apache server, or maybe using CouchDb, but I am not very sure of all the details to solve this problem. Could anyone suggest some clear approach as to how to solve this part ?

  I am trying to detect a midair collision problem (simultaneous editin) using selenium. So I start a selenium session A with following (Super Class) selenium = new MASSelenium(serverHost, serverPort, *iexplore, browserURL); selenium.start(); selenium.open("index.cgi"); then I try starting a different selenium session B pointing to a different browser from the superclass (Sub Class): selenium2 = new MASSelenium(getServerHost(), getServerPort(), *firefox, getBrowserURL()); selenium2.start(); selenium2.open("index.cgi"); It works fine on my local machine (behaves as expected) but then when i run this same test on a remote machine (using bamboo build tool), i get this exception: java.lang.RuntimeException: Could not start Selenium session: Internal Server Error at com.thoughtworks.selenium.DefaultSelenium.start(DefaultSelenium.java:89) at gov.baba.arc.mas.selenium.tests.SimultaneousEditingConflictDetected.setUp(SimultaneousEditingConflictDetected.java:78) Caused by: com.thoughtworks.selenium.SeleniumException: Internal Server Error at com.thoughtworks.selenium.HttpCommandProcessor.throwAssertionFailureExceptionOrError(HttpCommandProcessor.java:97) at com.thoughtworks.selenium.HttpCommandProcessor.getCommandResponseAsString(HttpCommandProcessor.java:168) at com.thoughtworks.selenium.HttpCommandProcessor.executeCommandOnServlet(HttpCommandProcessor.java:104) at com.thoughtworks.selenium.HttpCommandProcessor.doCommand(HttpCommandProcessor.java:86) Any idea why this is happening?

• How do you encrypt data between client and server running in Flash and Java?

  - by ArmlessJohn

  We have a multiclient system where the client is written in Flash and the server is written in Java. Currently, communication is done in Flash by usage of flash.net.Socket and the protocol is written in JSON. The server uses a custom port to receive connections and then proceed to talk with each client. As expected, data is sent and received on both fronts as raw bytes, which are then decoded as needed. We would like to encrypt the communication between clients and server. I have some basic understanding about public/private key encryption, but I do not know what is the best way to exchange keys or what libraries are available (on both languages) to do this. What would be the best strategy to attack this problem and where should I start looking for libraries/methods to implement this encryption?

• Easy plugin or procedure for sqlserver Management Studio to script row inserts.

  - by Patrick Karcher

  I've never been able to find a good script or plugin for sql server Management Studio (2005 and or 2008) for a very common scripting need: specifying a few/all rows in a table and scripting their insert. You can guess my story: I've got some configuration data in my dev db and I need to script it for deployment to UAT and then production. I've found a few cludgy systems in the past, that were more trouble than they were worth. I need something free and unobtrusive. Once I find it I'll share it with the other 20 developers in my shop who are annoyed by this. Aren't we all annoyed by this by the way? What is the best, easiest, free, way to specify a few/all rows in a table and get a script their insert?

• How to Store and Retrieve Images Using SQL Server (Server Management Studio)

  - by Joe Majewski

  I am having difficulties when trying to insert files into a SQL Server database. I'll try to break this down as best as I can: What data type should I be using to store image files (jpeg/png/gif/etc)? Right now my table is using the image data type, but I am curious if varbinary would be a better option. How would I go about inserting the image into the database? Does Microsoft SQL Server Management Studio have any built in functions that allow insertions of files into tables? If so, how is that done? Also, how could this be done through the use of an HTML form with PHP handling the input data and placing it into the table? How would I fetch the image from the table and display it on the page? I understand how to SELECT the cell's contents, but how would I go about translating that into a picture. Would I have to have a header(Content type: image/jpeg)? I have no problem doing any of these things with MySQL, but the SQL Server environment is still new to me, and I am working on a project for my job that requires the use of stored procedures to grab various data. Any and all help is appreciated.

• Single SQL Server Result Set from Query

  - by JamesC

  Hi Please advise on how to merge two results in to one using SQL Server 2005. I have the situation where an Account can have up to two Settlement Instructions and this have been modeled like so: The slim-ed down schema: Account --------------------- Id AccountName PrimarySettlementId (nullable) AlternateSettlementId (nullable) SettlementInstruction ---------------------- Id Name The output I want is a single result set with a select statement something along the lines of this which will allow me to construct some java objects in my Spring row mapper: select Account.Id as accountId, Account.AccountName as accountName, s1.Id as primarySettlementId, s1.Name as primarySettlementName, s2.Id as alternateSettlementId, s2.Name as alternateSettlementName I've tried various things but cannot find a way to get the result set merged in to one where the primary and alternate FK's are not null. Finally I have searched the forum, but nothing quite seems to fit with what I need.

• Powershell Transcript is empty when running script from SQL Agent Job in 2005 SQL Server

  - by Greg Bray

  I have a complex Powershell script that gets run as part of a SQL 2005 Server Agent Job. The script works fine, but it uses the "Start-Transcript $strLogfile -Append" command to log all of it's actions to a transcript file. The problem is that the transcript is always empty. It adds the header and footer to indicate that the transcript is starting and stopping, but it doesn't actually log anything. Example: ********************** Windows PowerShell Transcript Start Start time: 20100304173001 Username : xxxxxxxxxxxx\SYSTEM Machine : xxxxx-xxx (Microsoft Windows NT 5.2.3790 Service Pack 2) ********************** ********************** Windows PowerShell Transcript End End time: 20100304173118 ********************** When I execute the script from a command prompt or start - run everything works just fine. Here is the command used to run the script (same command used in the Operating system CmdExec step of the SQL Agent Job) powershell.exe -File "c:\temp\Backup\backup script.ps1" I first thought it must have something to do with the script running under the System account (default SQL Agent account), but even when I tried changing the SQL Agent to run under my own personal account it still created a blank transcript. Is there any way to get PowerShell Transcripts to work when executing them as part of a 2005 SQL Server Agent Job?

• Atomic UPSERT in SQL Server 2005

  - by rabidpebble

  What is the correct pattern for doing an atomic "UPSERT" (UPDATE where exists, INSERT otherwise) in SQL Server 2005? I see a lot of code on SO (e.g. see http://stackoverflow.com/questions/639854/tsql-check-if-a-row-exists-otherwise-insert) with the following two-part pattern: UPDATE ... FROM ... WHERE <condition> -- race condition risk here IF @@ROWCOUNT = 0 INSERT ... or IF (SELECT COUNT(*) FROM ... WHERE <condition>) = 0 -- race condition risk here INSERT ... ELSE UPDATE ... where will be an evaluation of natural keys. None of the above approaches seem to deal well with concurrency. If I cannot have two rows with the same natural key, it seems like all of the above risk inserting rows with the same natural keys in race condition scenarios. I have been using the following approach but I'm surprised not to see it anywhere in people's responses so I'm wondering what is wrong with it: INSERT INTO <table> SELECT <natural keys>, <other stuff...> FROM <table> WHERE NOT EXISTS -- race condition risk here? ( SELECT 1 FROM <table> WHERE <natural keys> ) UPDATE ... WHERE <natural keys> (Note: I'm assuming that rows will not be deleted from this table. Although it would be nice to discuss how to handle the case where they can be deleted -- are transactions the only option? Which level of isolation?) Is this atomic? I can't locate where this would be documented in SQL Server documentation.

• SQL Server 2008 - Editing Tables: Bit columns require 'True' or 'False'

  - by CJM

  Not so much a question as an observation... I'm just upgrading to SQL Server 2008 on my development machine in anticipation of upgrading my live applications. I didn't anticipate any problems since [I think] I generally use standard T-SQL, and probably not too far from ANSI standard SQL. So far so good, but I was really thrown by a very simple change: I was creating a simple, small look-up table to store a list of codes and including a bit column to indicate the current default code. But when I used the new/modified 'Edit Top 200 Rows' option, and entered my 0s and 1s in the the bit column I got an error: 'Invalid value for cell - String was not recognised as a valid boolean' After a bit of head-scratching, I tried True and False - and they worked. So it seems this new Edit feature requires 4 or 5 characters to be typed, rather than the previous 1. Checking further, we can still use '...where bitval = 1' but can now also use '...where bitval = 'true''. But any results returned render these bit columns as 0 or 1 still. It all sounds like half a step backwards. Not the end of the world, but and unnecessary annoyance. Does anybody have any insight on this issue? Or there any other new Gotchas with SQL Server 2008?

• SQL Server 2005 standard filegroups / files for performance on SAN

  - by Blootac

  Ok so I've just been on a SQL Server course and we discussed the usage scenarios of multiple filegroups and files when in use over local RAID and local disks but we didn't touch SAN scenarios so my question is as follows; I currently have a 250 gig database running on SQL Server 2005 where some tables have a huge number of writes and others are fairly static. The database and all objects reside in a single file group with a single data file. The log file is also on the same volume. My interpretation is that separate data files should be used across different disks to lessen disk contention and that file groups should be used for partitioning of data. However, with a SAN you obviously don't really have the same issue of disk contention that you do with a small RAID setup (or at least we don't at the moment), and standard edition doesn't support partitioning. So in order to improve parallelism what should I do? My understanding of various Microsoft publications is that if I increase the number of data files, separate threads can act across each file separately. Which leads me to the question how many files should I have. One per core? Should I be putting tables and indexes with high levels of activity in separate file groups, each with the same number of data files as we have cores? Thank you

• Sql Server Compact - Schema Management

  - by Richard B

  I've been searching for some time for a good solution to implement the idea of managing schema on a Sql Server Compact 3.5 db. I know of several ways of managing schema on Sql Express/std/enterprise, but Compact Edition doesn't support the necessary tools required to use the same methodology. Any suggestions/tips? I should expand this to say that it is for 100+ clients with wrapperware software. As the system changes, I need to publish update scripts alongside the new binaries to the client. I was looking for a decent method by which to publish this without having to just hand the client a script file and say "Run this in SSMSE". Most clients are not capable of doing such a beast. A buddy of mine disclosed a partial script on how to handle the SQL Server piece of my task, but never worked on Compact Edition... It looks like I'll be on my own for this. What I think that I've decided to do, and it's going to need a "geek week" to accomplish, is that I'm going to write some sort of tool much like how WiX and nAnt works, so that I can just write an overzealous Xml document to handle the work. If I think that it is worthwhile, I'll publish it on CodePlex and/or CodeProject because I've used both sites a bit to gain better understanding of concepts for jobs I've done in the past, and I think it is probably worthwhile to give back a little.
