  • weird postgresql log entries

    - by hyperboreean
    I am trying to figure out why I get some weird entries in my postgresql log after I do a restart: 2010-05-14 11:30:25 EEST LOG: database system was shut down at 2010-05-14 11:30:22 EEST 2010-05-14 11:30:25 EEST LOG: autovacuum launcher started 2010-05-14 11:30:25 EEST LOG: database system is ready to accept connections 2010-05-14 11:30:25 EEST LOG: incomplete startup packet 2010-05-14 11:30:40 EEST WARNING: there is already a transaction in progress 2010-05-14 11:30:40 EEST LOG: could not receive data from client: Connection reset by peer 2010-05-14 11:30:40 EEST LOG: unexpected EOF on client connection First, there's the 2010-05-14 11:30:25 EEST LOG: incomplete startup packet which bugs me.

  • 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

  • Monit can't detect MySQL, but I can

    - by Matchu
    Monit is configured to watch MySQL on localhost at port 3306. check process mysqld with pidfile /var/lib/mysql/li175-241.pid start program = "/etc/init.d/mysql start" stop program = "/etc/init.d/mysql stop" if failed port 3306 protocol mysql then restart if 5 restarts within 5 cycles then timeout My application, which is configured to connect to MySQL via localhost:3306, is running just fine and can access the database. I can even use MySQL Query Browser to connect to the database remotely via port 3306. The port is totally open and possible to connect to. Therefore, I'm pretty darn certain that it's running. However, running monit -v reveals that Monit cannot detect MySQL on that port. 'mysqld' failed, cannot open a connection to INET[localhost:3306] via TCP This happens consistently, until Monit decides not to track MySQL anymore, as configured. How can I begin to troubleshoot this issue?

  • Exchange Server Contact Categories - How to Remove/Update All

    - by ben
    I've been tasked with cleaning up our companies contact database sitting on our Exchange Server 2003. The rub is this database of contacts has been neglected for the past couple of years and is now a bit messy. My issue is I have say a person named 'Bob Smith', and Bob is listed in multiple categories, 'Students' and 'Student'. I would really like to remove the 'Student' category from Bob and anyone else out there that has the same category. My question is, is there an easy way to edit the master category lists for contacts on the exchange server? I feel like I am missing something simple here since if I were playing with the categories that I use, to say organize email its very easy to do so, but I can't seem to find the proper way to do it for categories that are up on the server. I'm attempting to work through Outlook 2007 and Exchange 2003. Any insight would be very helpful as I really don't want to change 8000+ contacts by hand.

  • Webserver max CPU when apache and MYSQL are ran together

    - by Tim
    This website has been running fine without issues, Recently it went down. After some investigation it looks like the combo of MYSQL and Apache bring the box to its knees. Apache can run find serving static web pages and MYSQL can run fine when the website isn't working. As soon as the website is enabled with SQL running the CPU on the box remains at 100%. Picture of the usage: http://i.stack.imgur.com/GG2NC.png I've checked the sql database for errors, tried tuning nearly every parameter in apache/sql's conf file for performance. The server is a redhat based box running the latest software packages. Any help/suggestions are welcome. Doing an strace on a high cpu apache process I see the following: read(14, "", 8192) = 0 close(14) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 14 fcntl64(14, F_SETFL, O_RDONLY) = 0 fcntl64(14, F_GETFL) = 0x2 (flags O_RDWR) connect(14, {sa_family=AF_FILE, path="/var/lib/mysql/mysql.sock"...}, 110) = 0 setsockopt(14, SOL_SOCKET, SO_RCVTIMEO, "\2003\341\1\0\0\0\0", 8) = 0 setsockopt(14, SOL_SOCKET, SO_SNDTIMEO, "\2003\341\1\0\0\0\0", 8) = 0 setsockopt(14, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported) setsockopt(14, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0 Here is what I see from a mysql process: futex(0x86fc9a4, FUTEX_WAIT_PRIVATE, 39, NULL) = 0 futex(0x86fc734, FUTEX_WAIT_PRIVATE, 2, NULL) = 0 futex(0x86fc734, FUTEX_WAKE_PRIVATE, 1) = 0 gettimeofday({1301465020, 141613}, NULL) = 0 clock_gettime(CLOCK_REALTIME, {1301465020, 141699633}) = 0 futex(0x8707a64, FUTEX_WAIT_PRIVATE, 1, {4, 999913367}) = 0 futex(0x8707a40, FUTEX_WAIT_PRIVATE, 2, NULL) = 0 futex(0x8707a40, FUTEX_WAKE_PRIVATE, 1) = 0 exit_group(0) = ?

  • How to generate the right password format for Apache2 authentication in use with DBD and MySQL 5.1?

    - by Walkman
    I want to authenticate users for a folder from a MySQL 5.1 database with AuthType Basic. The passwords are stored in plain text (they are not really passwords, so doesn't matter). The password format for apache however only allows for SHA1, MD5 on Linux systems as described here. How could I generate the right format with an SQL query ? Seems like apache format is a binary format with a lenght of 20, but the mysql SHA1 function return 40 long. My SQL query is something like this: SELECT CONCAT('{SHA}', BASE64_ENCODE(SHA1(access_key))) FROM user_access_keys INNER JOIN users ON user_access_keys.user_id = users.id WHERE name = %s where base64_encode is a stored function (Mysql 5.1 doesn't have TO_BASE64 yet). This query returns a 61 byte BLOB which is not the same format that apache uses. How could I generate the same format ? You can suggest other method for this too. The point is that I want to authenticate users from a MySQL5.1 database using plain text as password.

  • Slow Local Network, Windows 7, Snow Leopard, WiFi/Wired

    - by WerkkreW
    Hello - I am experiencing really poor local network performance in my home. I was recently using a Linksys WRT54G Router with DD-WRT on it, and a couple comparable Linksys-G PCI cards for connectivity but decided to upgrade hoping it would help with my performance issues. The computers in my house are connected as follows: Comcast Business Class Commercial 25mbps/10mbps (Verified with SpeakEasy and Speedtest.net) D-Link DGL-4500 Wireless N Router Windows 7x64 - D-Link DWA-552 Wireless-N Windows 7x64 - D-Link DWA-552 Wireless-N Mac Mini 10.6.2 - AirPort Extreme N Playstation 3, Hard Wired Xbox 360, Hard Wired Essentially the problem is very specific. Web browsing and uploading/downloading files from the internet is fine, more than fine. But if I want to say, Stream a video from one of my Windows 7 computers to my PS3, or copy a large video file between either of the PC's or the Mac, I get a consistent 500-900Kbps throughput at the high end. If I open my network browser, or try to browse my homegroup the response time is horrible. Both of my Windows computers are showing Strong wireless signals with a connection speed of 300Mbps. I know I can never expect to achieve anything near those speeds, but 500Kbps? Here is what I have tried so far: Enabled Single mode N-only and N/G Only on router WPA2 with AES Encrpytion Disabled "Remote Differential Compression" in Windows 7 Disabled TCP "Auto-Tuning" Used other software for file copies such as "Teracopy" I am at the end of my rope. Unfortunately I live in a 75 year old home with plaster walls, so hard-wiring my entire house isn't really an option I can handle right now. Any ideas to help me get decent speed when transferring files across my network would be greatly appreciated.

  • Forwarding ports with ssh on Linux

    - by Patrick Klingemann
    I have a database server, let's call it: dbserver I have a web server with access to my dbserver, let's call it: webserver I have a development machine that I'd like to use to access a database on dbserver, let's call it: dev dbserver has a firewall rule set to allow TCP requests from webserver to dbserver:1433 I'd like to set up a tunnel from dev:1433 to dbserver:1433, so all requests to 1433 on dev are passed along to dbserver:1433 My sshd_config on webserver has the following rules set: AllowTcpForwarding yes GatewayPorts yes This is what I've tried: ssh -v -L localhost:1433:dbserver:1433 webserver In another terminal: telnet localhost 1433 Results in: Trying ::1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. Any idea what I'm doing wrong here? Thanks in advance!

  • ldap sync with outlook

    - by Dr Casper Black
    I have a task to research the possibilities of LDAP as a centralized Address Book. I have setup a openLDAP on debian 5.07. I managed to search the LDAP contacts from MS Outlook 2007 (with some drawbacks like Outlook cant recognize street and organization fields). My question is, is it possible ,& how, to sync data on LDAP server with applications that support LDAP? I could not find any data on this topic. EDIT: The point is, to have a centralized list of contacts that can be sync with various applications, for instance Outlook, Thunderbird, Phonebook on mobile phones...etc The Question is, Is it possible to transfer (update) data on a client application from LDAP database and viceversa? So not to search LDAP server data, but to download contact that are not available in the client application (Outlook) and upload data to LDAP if the contact is in (Outlook) and not in LDAP database and the other way around, in other words synchronize.

  • Microsoft Cluster or Oracle Fail Safe error

    - by osdm
    Trying to get Oracle Database 10g to work on Microsoft cluster (using Oracle Fail Safe, not RAC). Everything installed, but when trying to verify group or add database to group I get following error: FS-10220: Network name MSK00-NST01-1 maps to IP address 10.1.11.74 in the cluster resource but maps to IP address 10.1.1.74 on the system MSK00-NST01-1 is cluster name, 10.1.11.74 is first node IP, 10.1.1.74 is second node IP. Oracle documentation says "The cluster and the system must have the same IP address mapping for a network name. Check that either the network name server or the local host file has the same IP address mapping as the cluster." Where is the error - in Oracle configuration or in cluster configuration? What are possible ways to correct it? Thanks a lot for any ideas.

  • SQL Server Management Studio - Error connecting to remote DB

    - by Julien Poulin
    All right, here is the deal: I'm connecting to a Windows 2003 Server using VPN. On this server, there is a remote SQL Server 2005 Express engine. I can connect to the database using Visual Studio 2008. What I can't do though, is connect to this same database with SQL Server 2005 Management Studio (Standard). I have checked the connection info a hundred times and still nothing. One thought: do VS ans SSMS use the same sql provider? Note: I'm running Windows 7 RC. I had absolutely no problem using the same config under Vista. This is the error I get when trying to connect with SSMS:

  • How can Windows defragmentation tools cause internal fragmentation in SQL Server?

    - by Martin
    I was just reading this article where the author talks about the file system fragmentation that can be caused by growing database files. There was one bit that I didn't quite follow. What about Windows defragmentation tools? Although you can use a Windows defragmentation tool to defragment your database files, these tools simply move chunks of files around to get them contiguous. This moving of chunks of files can cause internal fragmentation that you might not be able to resolve easily. Is the author saying here that the disc defragmenter makes no attempt to put the chunks of files in the correct sequence or have I misunderstood? If he is saying that then is this a limitation of all disc defragmenter utilities - even commercial ones?

  • MySQL Windows vs. Linux: performance, caveats, pros and cons?

    - by gravyface
    Looking for (preferrably) some hard data or at least some experienced anecdotal responses with regards to hosting a MySQL database (roughly 5k transactions a day, 60-70% more reads than writes, < 100k of data per transaction i.e. no large binary objects like images, etc.) on Windows 2003/2008 vs. a Debian-based derivative (Ubuntu/Debian, etc.). This server will function only as a database server with a separate Web server on another physical box; this server will require remote access for management (SSH for Linux, RDP for Windows). I suspect that the Linux kernel/OS will compete less than the Windows Server for resources, but for this I can't be certain. There's also security footprint: even with Windows 2008, I'm thinking that the Linux box can be locked down more easily than the Windows Server. Anyone have any experience with both configurations?

  • How do large blobs affect SQL delete performance, and how can I mitigate the impact?

    - by Max Pollack
    I'm currently experiencing a strange issue that my understanding of SQL Server doesn't quite mesh with. We use SQL as our file storage for our internal storage service, and our database has about half a million rows in it. Most of the files (86%) are 1mb or under, but even on fresh copies of our database where we simply populate the table with data for the purposes of a test, it appears that rows with large amounts of data stored in a BLOB frequently cause timeouts when our SQL Server is under load. My understanding of how SQL Server deletes rows is that it's a garbage collection process, i.e. the row is marked as a ghost and the row is later deleted by the ghost cleanup process after the changes are copied to the transaction log. This suggests to me that regardless of the size of the data in the blob, row deletion should be close to instantaneous. However when deleting these rows we are definitely experiencing large numbers of timeouts and astoundingly low performance. In our test data set, its files over 30mb that cause this issue. This is an edge case, we don't frequently encounter these, and even though we're looking into SQL filestream as a solution to some of our problems, we're trying to narrow down where these issues are originating from. We ARE performing our deletes inside of a transaction. We're also performing updates to metadata such as file size stats, but these exist in a separate table away from the file data itself. Hierarchy data is stored in the table that contains the file information. Really, in the end it's not so much what we're doing around the deletes that matters, we just can't find any references to low delete performance on rows that contain a large amount of data in a BLOB. We are trying to determine if this is even an avenue worth exploring, or if it has to be one of our processes around the delete that's causing the issue. Are there any situations in which this could occur? Is it common for a database server to come to the point of complete timeouts when many of these deletes are occurring simultaneously? Is there a way to combat this issue if it exists? (cross-posted from StackOverflow )

  • Deleted one membership table. Possible to import without breaking relationship?

    - by superexsl
    Hey, I hope this isn't going to be tricky/time consuming, so fingers crossed. I'm working with the ASP.NET membership table. However, I've got quite a few other tables that I've built, and most of them have a relationship with the dbo.aspnet_Membership table. I've accidentally deleted the dbo.aspnet_Membership table and can't get it back. There was no major data on it, (as it's on my local machine), but I would really like to copy and paste that one table from another database I have, mainly for the sake of not breaking the schema. Is this possible? I'm worried if I run the Aspnet_regsql.exe tool, it's going to break the schema and remove all data from the tables as well the relationships (which would take a while to re-establish). Is there any way I can import just the dbo.aspnet_Membership table into my current database? Thanks for the any advice!

  • Script for checking the nologin accounts and then disable the account

    - by suma
    "Could you please share the scripts which does the below ?" I have written a script that scans all the relevent logs daily, makes a list of people that have had any activity that day, and maintains database (just a text file) of users and the last time they logged in. Then I have a second script that examines the database for dates more than x days ago, an notifies the user and administrator 2 weeks prior to locking the account. And if there are any dates more than x+y days ago, deletes the account altogether. This seems to be working for me - but I would like to use a non-proprietary solution if one is available.

  • MySQL mistake with grant option

    - by John Tate
    I am unsure reading the MySQL documentation if creating a user with the GRANT option will give them the power to create users and grant privileges, or change the privileges of other users databases. I have been creating databases for users like this CREATE DATABASE user; USE user; GRANT ALL PRIVILEGES ON *.* TO 'user'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION; Is this the best way of doing it or have I just given my users too much control? They are people I am hosting sites for. Thankfully at this point they are trustworthy. I use quotas. Edit: I have realized I have been granting users access to all databases. This is obviously stupid I should be using this: GRANT ALL PRIVILEGES ON database.* to 'user'@localhost' IDENTIFIED BY 'password' What is the simplest way to revoke privileges for every user except root so I can quickly end this catastrophic rookie mistake?

  • How to upgrade a single instance's size without downtime

    - by Justin Meltzer
    I'm afraid there may not be a way to do this since we're not load balancing, but I'd like to know if there is any way to upgrade an EC2 EBS backed instance to a larger size without downtime. First of all, we have everything on one instance: both our app and our database (mongodb). This is along the lines i'm thinking: I know you can create snapshots of your EBS and an AMI of your instance. We already have an AMI and we create hourly snapshots. If I spin up a new separate instance of a larger size and then implement (not sure what the right term is here) the snapshots so that our database is up to date, then I could switch the A record of our domain from the old ip address to the new one. However, I'm afraid that after copying over the data from the snapshot, by the time it takes to change the A record and have that change propagate, the data could potentially be stale. Is there a way to prevent this, and is there a better way to do this than I am suggesting?

  • concrete uses of LDAP?

    - by ajsie
    im new to LDAP. i wonder what are some concrete examples of using LDAP. things that are MUCH more easier to do when you got 3-7 linux computers in a small company network. one use that is very important for me seems to be that you configure LDAP to handle system authentication. then you dont have to create same accounts in all computers. are there other things that are a MUST DO for a small network to save more time? my small network is for apache servers and database servers. and should LDAP be in an own machine? cause i guess its not good to put it in apache or database servers since these are performance dependent.

  • sql server log shipping

    - by voam
    I am setting up log shipping with two 2008 sql servers connecting with a vpn. As far as I know as long as the sql agent is able to access the share on the primary/secondary servers everything will work. When I set up the Log shipping on the primary server using SQL Mangagement Studio, before I can set any of the "Secondary Database Settings" it asks me to connect to the secondary server. But I really don't want to open up the connection to the secondary server. I will be initialing this secondary database with a backup so as long as the transaction logs get copies everything should work. How to I work around the GUI not enabling any of the settings for the secondary server until I actually connect to it? Thanks in advance!

  • Clone MySQL DB - errors with CREATE VIEW/SHOW VIEW privileges

    - by user43537
    Running MySQL 5.0.32 on Debian 4.0 (Etch). I'm trying to clone a WordPress MySQL database completely (structure and data) on the same server. I tried a dump to an .sql file and an import into a new empty database from the command line, but the import fails with errors saying the user does not have the "SHOW VIEW" or "CREATE VIEW" privilege. Trying it with PHPMyAdmin doesn't work either. I also tried doing this with the MySQL root user (not named "root" though) and it shows an "Access Denied" error. I'm terribly confused as to where the problem is. Any pointers on cloning a MySQL DB and granting all privileges to a user account would be great (specifically for MySQL 5.0.32). Thanks!
