  • Need help configurating my Tomcat server

    - by gablin
    I just reinstalled my entire server, and now I can't seem to get my JSP-based website to work on Tomcat anymore. I use the same server.xml file, which worked perfectly before the reinstallation, but no longer. Here's the content of the server.xml file which worked before: <!--APR library loader.

  • how to log trigger intiated CRUD queries on postgresql 8.4

    - by user47650
    in the postgresql config file there is an option log_statement = 'mod' which causes CRUD statements to be logged. However this does not include the CRUD statements that are called from trigger functions, which means that following the log file is not useful to determine what changes are being made to the database data, if the 3rd part application has been making lots of changes using triggers. Is there some other option I can use to include trigger CRUD? alternatively, can I inspect the pg_xlog in real time using some tool? (xlogdump and xlogviewer do not work with version 8.4, i have tried)

  • 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?

  • What options are there for generating custom text snippets on the Mac?

    - by Moses
    As I am getting more heavily into programming as a job and no longer as a hobby, I am definitely in need of some ways to improve my productivity. One thing that would definitely help in that respect is being able to create customized keyboard shortcuts for text/code snippets. For instance, holding down CMD+L+O+R+E+M will output a paragraph or two of the Lorem ipsum filler text, or CMD+F+U creates a function declaration. What I am ideally looking for is a database where I can store formatted text snippets, bind them to my choice of keystrokes, and then have the text paste whenever I perform the associated keystrokes. Are there any stand-alone applications that can do this for a Mac. Also, are there any text editors / IDEs that have this ability built in?

  • MySQL taking a long time to start

    - by Dscoduc
    I'm running Windows Server 2008 with MySQL installed and every time I reboot the server the MySQL Service doesn't start right away. A look into the Windows Eventlog shows that the MySQL Service was hung at startup. Looking at the Services.msc console shows the service state at Starting... Eventually, like 10 minutes, the MySQL Service actually finishes the startup process and the database becomes available for my Wordpress server... I looked at the MySQL .err files and didn't find anything that would indicate a delay in the statup process... Can anyone suggest a way to determine what is causing the delay, and more importantly, how to prevent the delay in the MySQL Startup?

  • Ubuntu 12.04 VPS doesn't boot with mysql in nsswitch.conf

    - by chrisv
    1and1 VPS ("dynamic cloud server") does not boot any more as soon as mysql lookup is enabled in nsswitch.conf - any suggestions appreciated. Minimal setup to reproduce the problem: install Ubuntu 12.04 / LTS minimal server image install mysql-server, libnss-mysql-bg, nscd configure /etc/libnss-mysql.cfg and /etc/libnss-mysql-root.cfg set up appropriate database tables configure nss lookups through mysql in nsswitch.conf passwd: compat mysql group: compat mysql shadow: compat mysql Now, when I try to reboot the server it just hangs. No logs (maybe due to /var not yet being mounted), and I can't see console output (since this is a VPS). Booting into recovery image and removing "mysql" from /etc/nsswitch.conf makes the system bootable again, so this is definitely related to nsswitch/libnss-mysql-bg. There's a thread on gentoo-users which seems to describe a similar problem, unfortunately there's no real solution described, also the thread is rather old (from 2006) so I'm not sure whether this applies to me at all.

  • Adding a MySQL StoredProcedure causes not responding state

    - by Omie
    Hello I'm on Windows 7 ultimate 32bit + xampp 1.7.2 [MySQL v5.1.37] This is my stored procedure : delimiter // CREATE PROCEDURE updatePoints(IN parentid INT(5),IN userid INT(5)) DECLARE chpoints INT(5); BEGIN SELECT points INTO chpoints FROM quiz_challenges WHERE id = parentid; UPDATE quiz_users SET points = points + chpoints WHERE forumid=userid; END; // delimiter ; At first it was showing error 1064 while creating stored procedure. I added delimiters part and when I tried running the query from phpmyadmin, Firefox went into not responding state. After that I started Internet Explorer and tried opening my pages which use the same database, it worked fine. However, I tried opening phpmyadmin and IE went into not responding state as well. I restarted both servers. Later restarted PC. Tried again but its same behavior. So whats wrong with this tiny little code ? Am I missing something which might be causing infinite loop ? Thanks

  • Speeding up ROW_NUMBER in SQL Server

    - by BlueRaja
    We have a number of machines which record data into a database at sporadic intervals. For each record, I'd like to obtain the time period between this recording and the previous recording. I can do this using ROW_NUMBER as follows: WITH TempTable AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY Machine_ID ORDER BY Date_Time) AS Ordering FROM dbo.DataTable ) SELECT [Current].*, Previous.Date_Time AS PreviousDateTime FROM TempTable AS [Current] INNER JOIN TempTable AS Previous ON [Current].Machine_ID = Previous.Machine_ID AND Previous.Ordering = [Current].Ordering + 1 The problem is, it goes really slow (several minutes on a table with about 10k entries) - I tried creating separate indicies on Machine_ID and Date_Time, and a single joined-index, but nothing helps. Is there anyway to rewrite this query to go faster?

  • How to add admin users in 389 LDAP, fedora directory server

    - by chandank
    I want to create couple of Admin users who have access to create/delete users on a particular group/Organization Unit. For example, User: uid=testadmin, ou=people, dc=my,dc=net Should have access to create new users/delete users under ou=People,dc=my,dc=net I tried with below ACI but did not work (target = "ldap:///ou=People,dc=my,dc=net")(targetattr = "*") (version 3.0;acl "testadmin Permissions";allow (proxy)(userdn = "ldap:///uid=testadmin,ou=people,dc=my,dc=net");) I am able to add administrative users from the Directory Server console, but this user data is not stored in ldif files and only stored in binary database at /var/lib/dirsrv/slap-ldap/db/. Only problem is these users have full power and I am not sure how to restrict their access.

  • Trouble migrating Joomla from Linux to Windows server

    - by Matt
    I'm having some trouble migrating a Joomla website from a Linux server to a Windows server. The database came over fine, Besides that, all I've done is download all the files from the current site, and change configuration.php so the log and tmp directories show "./tmp/" and "./logs/" I keep having an error in the PHP log stating PHP Fatal error: Class 'JTable' not found I've downloaded the site multiple times now, and I'm convinced this is a configuration problem, and not a missing file problem. I've even tried installing a mod for backup on the linux box to try and migrate the site, but sadly the mod had problems installing. The new server is running IIS 7.5 on Windows Web Server.

  • Can I change a MySQL table back and forth between InnoDB and MyISAM without any problems?

    - by Daniel Magliola
    I have a site with a decently big database, 3Gb in size, a couple of tables with a dozen million records. It's currently 100% on MyISAM, and I have the feeling that the server is going slower than it should because of too much locking, so I'd like to try going to InnoDB and see if that makes things better. However, I need to do that directly in production, because obviously without load this doesn't make any difference. However, I'm a bit worried about this, because InnoDB actually has potential to be slower, so the question is: If I convert all tables to InnoDB and it turns out i'm worse off than before, can I go back to MyISAM without losing anything? Can you think of any problems I might encounter? (For example, I know that InnoDB stores all data in ONE big file that only gets bigger, can this be a problem?) Thank you very much Daniel

  • slow DNS resolution

    - by Ehsan
    I have a DNS server that resolves all queries for an internal group of servers. It is a bind on CentOS 5.5 (same as RHEL5) and I have set it up to allow recursion and resolve direction without any forwarders. The problem I am facing is that it takes a freakishly long amount of time to resolve a name for the first time. (in the magnitudes of 20 sec) This causes clients to give timeout. When I set it to forward all to Google's public DNS, i.e. 8.8.8.8+8.8.4.4, it works very nicely (within a second). I tried monitoring the traffic on the net to see why it is doing this: [root@ns1 ~]# tcpdump -nnvvvA -s0 udp tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 23:06:36.137797 IP (tos 0x0, ttl 64, id 35903, offset 0, flags [none], proto: UDP (17), length: 60) 172.17.1.10.36942 > 172.17.1.4.53: [udp sum ok] 19773+ A? www.paypal.com.

E.g. dig www.paypal.com @192.35.51.30 works perfectly, consistently, and very fast. What do you think about this mystery?

  • Hyperic HQ says the server is down, but it is not!

    - by Diego Jancic
    Hi, I've been using HQ for a couple months now, and everything worked fine. But since yesterday all resources go down for a couple hours, and then everything restores to normal, and then go down again without doing anything. The server of course is working, the HQ server and agent are both working, and the IPs were not modified. I've tried to re-run the setup in the HQ agent, and it did not change anything. Agent is in Windows 2008, and Server is in Windows 2003. I'm using HQ Version 4.1.2 (build #1053 - May 06, 2009 - Release Build) Any hint? Thanks! Update: I guess (although I'm not sure) it stopped working when the disk on the server went full, with 0 bytes of free space. Of course I've freed more than 15gbs and restarted the HQ server/database.

  • Solaris disk I/O spike... which monitoring tools do I need?

    - by bonez05
    Hi all, My Solaris 10 websever / database server disk io keeps spiking at intermittent times. Using iostat -xtc 5 the reads / sec will jump from 3.0 to 1450.0 and %busy will jump to 98% The apache access log doesn't indicate anything out of the ordinary. In other words, requests aren't any higher than usual. top doesn't generate anything useful. The cpu usage is fine with mysql using about 20% and nothing else to speak of really. What monitoring tool should I be using to see what process is using excessive disk I/O? or if there are any other suggestions I'm all ears. Thanks

  • Mysql Master-ColdMaster

    - by enedebe
    I explain my case: I'm at Amazon AWS and I want to be fault tolerant on a entire region failure. My basic problem is to have the db in sync with 2 regions. My options: Master-Master (high lag) Hand made sync every 5 minutes Master-ColdMaster?! (copy on the fly but Master won't wait the other region commit) In my system we could afford loosing a piece of data (we're not a bank) the last inserts in the db, but we could not afford more than 10 minutes of downtime. The database is small and the level of inserts is low, and I wouldn't affect the normal usage waiting other region commit. Is the 3 solution posible? And the most important, once the primary fail how we can detect and change the rol between master-coldmaster -- coldmaster-master ? Is there any clean-mode to restore between failure? Thank's!

  • Installing Oracle Client 11.1.0.7 on Windows Server 2008 64-bit. What does "Install Location" and "S

    - by Anders
    I am trying to install Oracle Client 11.1.0.7 on a Windows Server 2008 64-bit. To some this might not be rocket science but I can't understand what the options under the install screen "Specify Home Details" mean. The defaults given suggest that I use Oracle Base and install software under my own account name. It also suggests that each user should have a separate Oracle Base. This seems counter intuitive to me. I am doing a server install after all. All I want to use the installation for is to connect to an Oracle Database from Reporting Services. Can I safely ignore this and just accept the defaults? What are the implications if I change the location to a common directory?

  • Use mod_rewrite or RedirectMatch to redirect oldfile.aspx?p=blah to newfile.php, ignoring ?p=blah

    - by Dan
    I've got a site with many incoming links to the old structure (gone for years), with tonnes of URL vars that are no longer relevant, as the database mappings were changed. So, I'd like to redirect: http://www.mysite.com/oldfile.aspx?p=1&c=2 to: http://www.mysite.com/newfile.php without the query string at the end. The actual query string varies - there are hundreds of them, but since they don't match up to a particular case anymore, I want to take people to the new index page for the content they're looking for, so they can find it from there. I currently use: RedirectMatch 301 ^/oldfile\.aspx$ /newfile.php This puts the query back on the end though. Can someone let me know the voodoo recipe I need?

  • Connect using sqlplus to db server through multiple tunnels

    - by Samuel Lindblom
    I would like to create an SQL Developer connection to a database through a couple of tunnels. The steps right now are: Connect to server A - connect to server B - run sqlplus against tnsname on a server that I do not have ssh access to. Is there an easy way of using SQL Developer instead of sqlplus? I have read through 20 articles on the subject and still have no idea how to actually make the connection. I understand that you can chain ssh -L commands to get the server connection, but I don't know how to use that connection in SQL Developer.

  • SQL restore from single file db to filegroup

    - by Mauro
    I have a 180GB MOSS 2007 database whose maintenance (i.e. backups and restores) are becoming a problem. Part of the issue can be resolved by splitting the three content sites down into their own site collections, however this will likely still leave me with a 100gb DB to deal with. Whilst this isnt entirely problematic for SQL it does mean that backups / restores take far too long. my idea is to split each of the databases to 30gb files, then to import the content into them which should distribute the content across the file groups,making it much easier / faster to backup/restore. Is there a way to backup from a single file and restore to a filegroup? If i have the wrong understanding of filegroups then I'm more than happy to find out other methods of managing the size of databases.

    I have Windows Server 2003 running in a virtual machine, running some software that is trying to update a database within transactions on my Windows 7 machine (the host for the VM). On my host I have edited the settings for Local DTC by selecting the following Client and Administration Allow Remote clients Allow Remote administration Transaction manager communication Allow inbound Allow outbound No authentication required However when I try to run the software I receive this error: MSDTC on server 'x' is unavailable. Whilst searching for fixes most just suggest making sure the service is running which I have. Cheers!

  • How to configure mysqldump to avoid max_allowed_packet error

    - by Leopd
    Honestly it baffles me that with a completely default installation of mysql if I run mysqldump with default parameters it generates a SQL file that can't be imported into another completely default installation of mysql. From what I can gather it's got something to do with the max_allowed_packet setting and/or the net_buffer_length setting. I've read a bunch about this, and tried tweaking it a bunch of ways on both the export and import sides, but it still doesn't work. I keep getting the packet too big error on import. From everything I've read, here's my best guess: mysqldump --net_buffer_length=50000 myschema > giant_file.sql Because I read here that mysqldump refers to max_allowed_packet as net_buffer_length because ... uhh ... anyway. Then to import mysql --max_allowed_packet=999999 myschema < giant_file.sql But this still doesn't work. How do I export / import the database???
