  • Segmentation fault on login to mysql

    - by numberwhun
    Hello everyone! I recently did a fresh install of Ubuntu on my laptop (HP dv7, AMD Dual Core with 4 gigs RAM). I am working on installing my development environment and tools and one of the first things I was working on is getting MySQL installed. The following was my configure statement with options: ./configure --prefix=/usr/local/mysql --with-big-tables --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock --with-named-curses-libs=/lib/libncurses.so.5.7 After I did the make;make install, I did the post configuration such as setting the root password and installing the mysqld daemon in its rightful place. My issue is when I try to log in to mysql to start using it, the following shows what happens: $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.1.42 Source distribution Segmentation fault I have searched Google extensively, I have searched through the mysql bugs database and I have yet to find anything that matches my issue. Here is the contents of my my.cnf file, in case you want to see it: $ cat /etc/my.cnf [mysqld] basedir=/usr/local/mysql datadir=/usr/local/mysql socket=/usr/local/mysql/tmp/mysql.sock [mysql.server] user=mysql #basedir=/var/lib [client] socket=/usr/local/mysql/tmp/mysql.sock [mysqld_safe] err-log=/usr/local/mysql/logs/mysqld.log pid-file=/var/run/mysqld/mysqld.pid I am really hoping that someone here can tell me what has gone wrong with my installation as I would really love to know. I welcome and look forward to all responses. Thank you in advance! Best regards, Jeff

  • Installing MySQL 5.1 on OS X 10.7 Lion

    - by xisal
    I am trying to install MySQL 5.1. I am on Lion, and when I remove all files associated with MySQL on my machine it still tells me that I have a newer version installed when I try to install it from the DMG file. Has anyone successfully installed MySQL 5.1 on Lion? I found a solution using Homebrew: Completely remove MySQL from your system (just in case) sudo rm /usr/local/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/My* vim /etc/hostconfig and removed the line MYSQLCOM=-YES- rm -rf ~/Library/PreferencePanes/My* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm -rf /var/db/receipts/com.mysql.* Source:http://stackoverflow.com/questions/1436425/how-do-you-uninstall-mysql-from-mac-os-x Install homebrew /usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)" Source: https://github.com/mxcl/homebrew/wiki/installation Install MySQL 5.1 via brew brew install mysql51 if that doesn't work, do this: brew install https://raw.github.com/adamv/homebrew-alt/master/versions/mysql51.rb Source: http://stackoverflow.com/questions/4359131/brew-install-mysql-on-mac-os/6399627#6399627 Make MySQL Work Create mysql.sock file touch /tmp/mysql.sock Install MySQL default tables /usr/local/Cellar/mysql51/5.1.58/bin/mysql_install_db ...or your path Source: http://stackoverflow.com/questions/4788381/getting-cant-connect-through-socket-tmp-mysql-when-installing-mysql-on-ma/5140849#5140849

  • Webserver: chrooted PHP gives mysql.sock error when attempting to reach mysql

    - by Jon L.
    Hey guys, I've configured an Ubuntu webserver with Nginx + PHP5-FPM. I've created a chrooted environment (using jailkit) that I'm tossing my developers into, from where they can develop their test applications. Chroot jail: /home/jail Nginx and PHP5-FPM run outside the chroot, but are configured to function with websites within the chrooted environment. So far, Nginx and PHP5-FPM are serving up files without issue, except for the following: When attempting to connect to MySQL, we receive this error: SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' Now, I believe the issue is due to the non-chrooted php.ini referencing mysqld.sock outside of the chroot environment (it's actually using the MySQL default setting currently). My question is, how can I configure PHP to access MySQL via loopback or similar? (Found that as a suggestion in a google result, but without any instructions) Or if I'm missing some other obvious setting, let me know. If there's an option of creating a hardlink (that would remain available even if mysql is restarted), that would be handy as well.

  • Installing MySQL 5.5 manually on Ubuntu 10.04 server, errors about "/tmp/mysql.sock"

    - by black sensei
    I've set up an Ubuntu server and wanted to install MySQL 5.5. I've been following these MySQL documentation steps. I have libaio dev installed. Everything went fine until I ran bin/mysqld_safe --user=mysql & It runs into an issue and never returns to the shell. The output of mysqld_safe is logging to /usr/local/mysql/data/host_name.err. When I checked that file, it was complaining about /tmp/mysql.sock. I can unfortunately describe just parts of the error, since before I started right now it deleted all the files I've started installing back then by mistake. Should I change the socket to /var/run/mysqld/mysqld.socket after copying the .cnf file to /etc? I've also checked the /var/run/mysqld directory and there is no mysqld.socket. How do I proceed? Thanks for reading this and helping out

  • How to enable error log in lighttpd properly?

    - by Tomaszs
    I have a Centos 5 system with Lighttpd and fastcgi enabled. It does log access but does not log errors. I have Internal Server Error 500 and no info in log and when I try to open not -existing file also - no info in error log. How to enable it properly? Below is list of modules that I've enabled: server.modules = ( "mod_rewrite", "mod_redirect", "mod_alias", # "mod_access", # "mod_cml", # "mod_trigger_b4_dl", # "mod_auth", "mod_status", "mod_setenv", "mod_fastcgi", # "mod_webdav", # "mod_proxy_core", # "mod_proxy_backend_fastcgi", # "mod_proxy_backend_scgi", # "mod_proxy_backend_ajp13", # "mod_simple_vhost", # "mod_evhost", # "mod_userdir", # "mod_cgi", # "mod_compress", # "mod_ssi", # "mod_usertrack", # "mod_expire", # "mod_secdownload", # "mod_rrdtool", "mod_accesslog" ) Here are setting of debugging: ## enable debugging #debug.log-request-header = "enable" #debug.log-response-header = "enable" #debug.log-request-handling = "enable" debug.log-file-not-found = "enable" #debug.log-condition-handling = "enable" Setting of path to error and access log: ## where to send error-messages to server.errorlog = "/home/lxadmin/httpd/lighttpd/error.log" #### accesslog module accesslog.filename = "/home/lxadmin/httpd/lighttpd/ligh.log" Settings of fastcgi: fastcgi.debug = 1 fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 12, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "2", "PHP_FCGI_MAX_REQUESTS" => "500" ) ))) And in included config file I have: server.errorlog = "/home/httpd/mywebsite.com/stats/mywebsite.com-error_log" What comes to log files: /home/httpd/mywebsite.com/stats/ -rw-r--r-- 1 apache apache 5173239 May 16 11:34 mywebsite.com-custom_log -rwxrwxrwx 1 root root 0 Mar 27 2009 mywebsite.com-error_log /home/lxadmin/httpd/lighttpd/ -rwxrwxrwx 1 apache apache 2184 Apr 22 22:59 error.log -rwxrwxrwx 1 apache apache 6088621 May 16 11:26 ligh.log I gave error logs chmod 777 for a try to check if it's the issue, but apparently it's not. So my question is: what to do to have error log enabled?

  • SQL SERVER – Backing Up and Recovering the Tail End of a Transaction Log – Notes from the Field #042

    - by Pinal Dave
    [Notes from Pinal]: The biggest challenge which people face is not taking backup, but the biggest challenge is to restore a backup successfully. I have seen so many different examples where users have failed to restore their database because they made some mistake while they take backup and were not aware of the same. Tail Log backup was such an issue in earlier version of SQL Server but in the latest version of SQL Server, Microsoft team has fixed the confusion with additional information on the backup and restore screen itself. Now they have additional information, there are a few more people confused as they have no clue about this. Previously they did not find this as a issue and now they are finding tail log as a new learning. Linchpin People are database coaches and wellness experts for a data driven world. In this 42nd episode of the Notes from the Fields series database expert Tim Radney (partner at Linchpin People) explains in a very simple words, Backing Up and Recovering the Tail End of a Transaction Log. Many times when restoring a database over an existing database SQL Server will warn you about needing to make a tail end of the log backup. This might be your reminder that you have to choose to overwrite the database or could be your reminder that you are about to write over and lose any transactions since the last transaction log backup. You might be asking yourself “What is the tail end of the transaction log”. The tail end of the transaction log is simply any committed transactions that have occurred since the last transaction log backup. This is a very crucial part of a recovery strategy if you are lucky enough to be able to capture this part of the log. Most organizations have chosen to accept some amount of data loss. You might be shaking your head at this statement however if your organization is taking transaction logs backup every 15 minutes, then your potential risk of data loss is up to 15 minutes. Depending on the extent of the issue causing you to have to perform a restore, you may or may not have access to the transaction log (LDF) to be able to back up those vital transactions. For example, if the storage array or disk that holds your transaction log file becomes corrupt or damaged then you wouldn’t be able to recover the tail end of the log. If you do have access to the physical log file then you can still back up the tail end of the log. In 2013 I presented a session at the PASS Summit called “The Ultimate Tail Log Backup and Restore” and have been invited back this year to present it again. During this session I demonstrate how you can back up the tail end of the log even after the data file becomes corrupt. In my demonstration I set my database offline and then delete the data file (MDF). The database can’t become more corrupt than that. I attempt to bring the database back online to change the state to RECOVERY PENDING and then backup the tail end of the log. I can do this by specifying WITH NO_TRUNCATE. Using NO_TRUNCATE is equivalent to specifying both COPY_ONLY and CONTINUE_AFTER_ERROR. It as its name says, does not try to truncate the log. This is a great demo however how could I achieve backing up the tail end of the log if the failure destroys my entire instance of SQL and all I had was the LDF file? During my demonstration I also demonstrate that I can attach the log file to a database on another instance and then back up the tail end of the log. If I am performing proper backups then my most recent full, differential and log files should be on a server other than the one that crashed. I am able to achieve this task by creating new database with the same name as the failed database. I then set the database offline, delete my data file and overwrite the log with my good log file. I attempt to bring the database back online and then backup the log with NO_TRUNCATE just like in the first example. I encourage each of you to view my blog post and watch the video demonstration on how to perform these tasks. I really hope that none of you ever have to perform this in production, however it is a really good idea to know how to do this just in case. It really isn’t a matter of “IF” you will have to perform a restore of a production system but more of a “WHEN”. Being able to recover the tail end of the log in these sever cases could be the difference of having to notify all your business customers of data loss or not. If you want me to take a look at your server and its settings, or if your server is facing any issue we can Fix Your SQL Server. Note: Tim has also written an excellent book on SQL Backup and Recovery, a must have for everyone.

  • MS SQL to MySQL using MySQL Migration Toolkit: permission issue

    - by Zeno
    I have a MS SQL imported into SQL Server 2008 from a .bak and I set it to Mixed mode. I have a SQL user (called "test") that can correctly access the database using SQL Server. I need to convert this to a MySQL database, so I got the MySQL Migration Toolkit. I pick "MS SQL Server" and then it asks for the hostname/username/password/database. I'm not 100% sure on these, but I used "localhost" (running on same computer), left the port as is (1433) and the username/password ("test") for the SQL Server. And I used the database name for the SQL Server database I'm looking to import. I clicked next, enter my MySQL database details and then attempt to run it and I get this error: Connecting to source database and retrieve schemata names. Initializing JDBC driver ... Driver class MS SQL JDBC Driver Opening connection ...

  • SQL SERVER – Reduce the Virtual Log Files (VLFs) from LDF file

    - by pinaldave
    Earlier, I wrote a quite note on SQL SERVER – Detect Virtual Log Files (VLF) in LDF. Because of this I got responses suggesting too many VLFs are bad for log file. This prompts to a simple question: “How many is ‘too many’ VLFs?” I suggest that you go and read an article written by Kimberly over here. I am sure that you are going to have a clear understanding of what a good number for your VLFs is from that article. If you have lots of VLFs, you can reduce them right away using the following method: (I am just attempting to write a working script over here.) USE AdventureWorks GO BACKUP LOG AdventureWorks TO DISK='d:\adtlog.bak' GO -- Get Logical file name of the log file sp_helpfile GO DBCC SHRINKFILE(AdventureWorks_Log,TRUNCATEONLY) GO ALTER DATABASE AdventureWorks MODIFY FILE (NAME = AdventureWorks_Log,SIZE = 1GB) GO DBCC LOGINFO GO Again, here I have assumed that your initial log size is 1 GB, but in reality you should select the number based on your own ideal size of the log file. If your log file grows to 10 GB every day, you may want to put the value as 10 GB. For accuracy, read what Kimberly’s original article says over here.

  • How to easily upgrade MySQL 5.0.32 to MySQL 5.1.20 or higher on Debian Etch?

    - by Ferdy
    I have a home server running Debian Etch with MySQL 5.0.32 on it. I'm not much of a Linux administrator but two years ago I installed the server and it runs fine. I used the official MySQL package for Debian at that time. Since then I have been happily making use of it. Now I need to use a MySQL function that is only available in MySQL 5.1.20 and higher. Therefore I would like to upgrade. I'm not that confident in messing with something I need every day so I wanted to check with you what the best upgrade path would be? Obviously I prefer a simple upgrade that keeps my database, users and settings in place as they are now.

  • New Replication, Optimizer and High Availability features in MySQL 5.6.5!

    - by Rob Young
    As the Product Manager for the MySQL database it is always great to announce when the MySQL Engineering team delivers another great product release.  As a field DBA and developer it is even better when that release contains improvements and innovation that I know will help those currently using MySQL for apps that range from modest intranet sites to the most highly trafficked web sites on the web.  That said, it is my pleasure to take my hat off to MySQL Engineering for today's release of the MySQL 5.6.5 Development Milestone Release ("DMR"). The new highlighted features in MySQL 5.6.5 are discussed here: New Self-Healing Replication ClustersThe 5.6.5 DMR improves MySQL Replication by adding Global Transaction Ids and automated utilities for self-healing Replication clusters.  Prior to 5.6.5 this has been somewhat of a pain point for MySQL users with most developing custom solutions or looking to costly, complex third-party solutions for these capabilities.  With 5.6.5 these shackles are all but removed by a solution that is included with the GPL version of the database and supporting GPL tools.  You can learn all about the details of the great, problem solving Replication features in MySQL 5.6 in Mat Keep's Developer Zone article.  New Replication Administration and Failover UtilitiesAs mentioned above, the new Replication features, Global Transaction Ids specifically, are now supported by a set of automated GPL utilities that leverage the new GTIDs to provide administration and manual or auto failover to the most up to date slave (that is the default, but user configurable if needed) in the event of a master failure. The new utilities, along with links to Engineering related blogs, are discussed in detail in the DevZone Article noted above. Better Query Optimization and ThroughputThe MySQL Optimizer team continues to amaze with the latest round of improvements in 5.6.5. Along with much refactoring of the legacy code base, the Optimizer team has improved complex query optimization and throughput by adding these functional improvements: Subquery Optimizations - Subqueries are now included in the Optimizer path for runtime optimization.  Better throughput of nested queries enables application developers to simplify and consolidate multiple queries and result sets into a single unit or work. Optimizer now uses CURRENT_TIMESTAMP as default for DATETIME columns - For simplification, this eliminates the need for application developers to assign this value when a column of this type is blank by default. Optimizations for Range based queries - Optimizer now uses ready statistics vs Index based scans for queries with multiple range values. Optimizations for queries using filesort and ORDER BY.  Optimization criteria/decision on execution method is done now at optimization vs parsing stage. Print EXPLAIN in JSON format for hierarchical readability and Enterprise tool consumption. You can learn the details about these new features as well all of the Optimizer based improvements in MySQL 5.6 by following the Optimizer team blog. You can download and try the MySQL 5.6.5 DMR here. (look under "Development Releases")  Please let us know what you think!  The new HA utilities for Replication Administration and Failover are available as part of the MySQL Workbench Community Edition, which you can download here .Also New in MySQL LabsAs has become our tradition when announcing DMRs we also like to provide "Early Access" development features to the MySQL Community via the MySQL Labs.  Today is no exception as we are also releasing the following to Labs for you to download, try and let us know your thoughts on where we need to improve:InnoDB Online OperationsMySQL 5.6 now provides Online ADD Index, FK Drop and Online Column RENAME.  These operations are non-blocking and will continue to evolve in future DMRs.  You can learn the grainy details by following John Russell's blog.InnoDB data access via Memcached API ("NotOnlySQL") - Improved refresh of an earlier feature releaseSimilar to Cluster 7.2, MySQL 5.6 provides direct NotOnlySQL access to InnoDB data via the familiar Memcached API. This provides the ultimate in flexibility for developers who need fast, simple key/value access and complex query support commingled within their applications.Improved Transactional Performance, ScaleThe InnoDB Engineering team has once again under promised and over delivered in the area of improved performance and scale.  These improvements are also included in the aggregated Spring 2012 labs release:InnoDB CPU cache performance improvements for modern, multi-core/CPU systems show great promise with internal tests showing:    2x throughput improvement for read only activity 6x throughput improvement for SELECT range Read/Write benchmarks are in progress More details on the above are available here. You can download all of the above in an aggregated "InnoDB 2012 Spring Labs Release" binary from the MySQL Labs. You can also learn more about these improvements and about related fixes to mysys mutex and hash sort by checking out the InnoDB team blog.MySQL 5.6.5 is another installment in what we believe will be the best release of the MySQL database ever.  It also serves as a shining example of how the MySQL Engineering team at Oracle leads in MySQL innovation.You can get the overall Oracle message on the MySQL 5.6.5 DMR and Early Access labs features here. As always, thanks for your continued support of MySQL, the #1 open source database on the planet!

  • MySQL Master-Master replication generating thousands of log files

    - by Andrew
    Today, I checked the /var/lib/mysql/ directory of a server in a master-master replication setup and noticed there were about 3,600 slave-relay.00xxxx files in there (where "xxxx" is an incrementing integer). They appear to be binary log files and don't take up much space (only about 42K), but are they an indication that something is wrong? They range in date from August until today with about 25 per day. Thanks for any help.

  • mysql master-slave setup with synchronous replication

    - by imaginative
    I have a very trivial mysql master-slave setup going on between two servers. The problem is, replication is asynchronous, and this can cause issues (even on a low latency link), if the master server was to crash after a COMMIT before the replication thread from the slave was able to fetch the last bin log. Is there anyway to force mysql to do synchronous commits so that data consistency is guaranteed in a mysql-slave relationship?

    I have a drupal 7 site using the Views module to back-end site content search results. The same query with the same dataset returns different results from MySQL 5.5.28 to MySQL 5.6.14. The results from 5.5.28 are the correct, expected results. The results from 5.6.14 are not. If, however, I simply move a column in the select statement, the query returns the correct results. Here is the code-generated query in question (modified for readability). I apologize for the length; I couldn't find a way to reproduce it without the whole query: SELECT DISTINCT node_node_revision.nid AS node_node_revision_nid, node_revision.title AS node_revision_title, node_field_revision_field_position_institution_ref.nid AS node_field_revision_field_position_institution_ref_nid, node_revision.vid AS vid, node_revision.nid AS node_revision_nid, node_node_revision.title AS node_node_revision_title, SUM(search_index.score * search_total.count) AS score, 'node' AS field_data_field_system_inst_name_node_entity_type, 'node' AS field_revision_field_position_college_division_node_entity_t, 'node' AS field_revision_field_position_department_node_entity_type, 'node' AS field_revision_field_search_lvl_degree_lvls_node_entity_type, 'node' AS field_revision_field_position_app_deadline_node_entity_type, 'node' AS field_revision_field_position_start_date_node_entity_type, 'node' AS field_revision_body_node_entity_type FROM node_revision node_revision LEFT JOIN node node_node_revision ON node_revision.nid = node_node_revision.nid LEFT JOIN field_revision_field_position_institution_ref field_revision_field_position_institution_ref ON node_revision.vid = field_revision_field_position_institution_ref.revision_id AND (field_revision_field_position_institution_ref.entity_type = 'node' AND field_revision_field_position_institution_ref.deleted = '0') LEFT JOIN node node_field_revision_field_position_institution_ref ON field_revision_field_position_institution_ref.field_position_institution_ref_target_id = node_field_revision_field_position_institution_ref.nid LEFT JOIN field_revision_field_position_cip_code field_revision_field_position_cip_code ON node_revision.vid = field_revision_field_position_cip_code.revision_id AND (field_revision_field_position_cip_code.entity_type = 'node' AND field_revision_field_position_cip_code.deleted = '0') LEFT JOIN node node_field_revision_field_position_cip_code ON field_revision_field_position_cip_code.field_position_cip_code_target_id = node_field_revision_field_position_cip_code.nid LEFT JOIN node node_node_revision_1 ON node_revision.nid = node_node_revision_1.nid LEFT JOIN field_revision_field_position_vacancy_status field_revision_field_position_vacancy_status ON node_revision.vid = field_revision_field_position_vacancy_status.revision_id AND (field_revision_field_position_vacancy_status.entity_type = 'node' AND field_revision_field_position_vacancy_status.deleted = '0') LEFT JOIN search_index search_index ON node_revision.nid = search_index.sid LEFT JOIN search_total search_total ON search_index.word = search_total.word WHERE ( ( (node_node_revision.status = '1') AND (node_node_revision.type IN ('position')) AND (field_revision_field_position_vacancy_status.field_position_vacancy_status_target_id IN ('38')) AND( (search_index.type = 'node') AND( (search_index.word = 'accountant') ) ) AND ( (node_revision.vid=node_node_revision.vid AND node_node_revision.status=1) ) ) ) GROUP BY search_index.sid, vid, score, field_data_field_system_inst_name_node_entity_type, field_revision_field_position_college_division_node_entity_t, field_revision_field_position_department_node_entity_type, field_revision_field_search_lvl_degree_lvls_node_entity_type, field_revision_field_position_app_deadline_node_entity_type, field_revision_field_position_start_date_node_entity_type, field_revision_body_node_entity_type HAVING ( ( (COUNT(*) >= '1') ) ) ORDER BY node_node_revision_title ASC LIMIT 20 OFFSET 0; Again, this query returns different sets of results from MySQL 5.5.28 (correct) to 5.6.14 (incorrect). If I move the column named "score" (the SUM() column) to the end of the column list, the query returns the correct set of results in both versions of MySQL. My question is: Is this expected behavior (and why), or is this a bug? I'm on the verge of reverting my entire environment back to 5.5 because of this.

  • SQL SERVER – Quiz and Video – Introduction to Basics of a Query Hint

    - by pinaldave
    This blog post is inspired from SQL Architecture Basics Joes 2 Pros: Core Architecture concepts – SQL Exam Prep Series 70-433 – Volume 3. [Amazon] | [Flipkart] | [Kindle] | [IndiaPlaza] This is follow up blog post of my earlier blog post on the same subject - SQL SERVER – Introduction to Basics of a Query Hint – A Primer. In the article we discussed various basics terminology of the query hints. The article further covers following important concepts of query hints. Expecting Seek and getting a Scan Creating an index for improved optimization Implementing the query hint Above three are the most important concepts related to query hint and SQL Server.  There are many more things one has to learn but without beginners fundamentals one can’t learn the advanced  concepts. Let us have small quiz and check how many of you get the fundamentals right. Quiz 1) You have the following query: DECLARE @UlaChoice TinyInt SET @Type = 1 SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice You have a nonclustered index named IX_Legal_Ula on the UlaChoice field. The Primary key is on the ID field and called PK_Legal_ID 99% of the time the value of the @UlaChoice is set to ‘YP101′. What query will achieve the best optimization for this query? SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice WITH(INDEX(X_Legal_Ula)) SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice WITH(INDEX(PK_Legal_ID)) SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice OPTION (Optimize FOR(@UlaChoice = ‘YP101′)) 2) You have the following query: SELECT * FROM CurrentProducts WHERE ShortName = ‘Yoga Trip’ You have a nonclustered index on the ShortName field and the query runs an efficient index seek. You change your query to use a variable for ShortName and now you are using a slow index scan. What query hint can you use to get the same execution time as before? WITH LOCK FAST OPTIMIZE FOR MAXDOP READONLY Now make sure that you write down all the answers on the piece of paper. Watch following video and read earlier article over here. If you want to change the answer you still have chance. Solution 1) 3 2) 4 Now compare let us check the answers and compare your answers to following answers. I am very confident you will get them correct. Available at USA: Amazon India: Flipkart | IndiaPlaza Volume: 1, 2, 3, 4, 5 Please leave your feedback in the comment area for the quiz and video. Did you know all the answers of the quiz?

  • cannot log into mysql locally

    - by Lostsoul
    When I try to log into mysql locally using the command: mysql -u root -p I get this error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) I can access the server remotely(not as root) and my web pages are using the mysql fine, but locally I cannot log on(which I need because I need to create some users). Only change I made was to attach another drive to the server and move the sql data there. Here's my.cnf [mysqld] datadir=/media/ephemeral0/data/mysql socket=/media/ephemeral0/data/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # adding more config skip-external-locking long_query_time=1 slow_query_log slow_query_log_file=/var/log/log-slow-queries.log log-bin=mysql-bin server-id= 1 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid myisam_recover_options I read I need to edit the socket info in my.cnf to make sure it points to the right socket file..I double checked and the file exists(although it starts with an S when I do ls -l "srwxrwxrwx 1 mysql mysql 0 Jun 21 03:43 mysql.sock"). I'm not really sure how to resolve this. I have tried to reboot and ran yum update to make sure I was running the latest packages. Please help!

  • Analyze your IIS Log Files - Favorite Log Parser Queries

    The other day I was asked if I knew about a tool that would allow users to easily analyze the IIS Log Files, to process and look for specific data that could easily be automated. My recommendation was that if they were comfortable with using a SQL-like language that they should use Log Parser. Log Parser is a very powerful tool that provides a generic SQL-like language on top of many types of data like IIS Logs, Event Viewer entries, XML files, CSV files, File System and others; and it allows you...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Java-JDBC-MySQL Error

    - by LeonardPeris
    I'm trying to get my java program to talk to a MySQL DB. So i did some reading and downloaded MySQL Connector/J. I've extracted it into my home directory ~. Here are the contents. user@hamster:~$ ls LoadDriver.class LoadDriver.java mysql-connector-java-5.1.18-bin.jar The contents of LoadDriver.java are user@hamster:~$ cat LoadDriver.java import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; // Notice, do not import com.mysql.jdbc.* // or you will have problems! public class LoadDriver { public static void main(String[] args) { try { // The newInstance() call is a work around for some // broken Java implementations Class.forName("com.mysql.jdbc.Driver").newInstance(); } catch (Exception ex) { System.out.println(ex); } } } The contents are the same from http://dev.mysql.com/doc/refman/5.1/en/connector-j-usagenotes-basic.html#connector-j-usagenotes-connect-drivermanager with the only change that the Exception is being printed to console in the catch block. I compile it as follows leonard@hamster:~$ javac LoadDriver.java When I try to execute it, the following is the ouput. leonard@hamster:~$ java LoadDriver java.lang.ClassNotFoundException: com.mysql.jdbc.Driver This output is consistent with the executing command, but when trying to run it with the prescribed CLASSPATH method I run into the following issue. leonard@hamster:~$ java -cp /home/leonard/mysql-connector-java-5.1.18-bin.jar LoadDriver Exception in thread "main" java.lang.NoClassDefFoundError: LoadDriver Caused by: java.lang.ClassNotFoundException: LoadDriver at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) Could not find the main class: LoadDriver.

  • HTTP, JSON, JavaScript, Map and Reduce built-in to MySQL

    - by Bertrand Matthelié
    Oracle MySQL Engineer Ulf Wendel delivered yesterday a talk about his Proof of Concept at the International PHP Conference in Berlin entitled: “HTTP, JSON, JavaScript, Map and Reduce built-in to MySQL - make it happen, today.” The presentation has been featured today on the home page of SlideShare, both into the “Hot on Facebook” and “Hot on Twitter” sections. Well done, Ulf! Especially just before the wedding…:) Presentation abstract: See how a MySQL Server plugin can be developed to build all this into MySQL. A new direct wire between MySQL and client-side JavaScript is created. MySQL speaks HTTP, replies JSON and offers server-side JavaScript. Server-side JavaScript gets access to MySQL data and does Map&Reduce of JSON documents stored in MySQL. Fast? 2-4x faster than proxing client-side JavaScript request through PHP/Apache. Reasonable results... Slides available here. And, talking about innovation… today is Oracle’s MySQL Innovation Day, you can still attend the event online. Register Now, it starts at 9.00 am PT.

  • logrotate isn't rotating a particular log file (and i think it should be)

    - by Max Williams
    Hi all. For a particular app, i have log files in two places. One of the places has just one log file that i want to use with logrotate, for the other location i want to use logrotate on all log files in that folder. I've set up an entry called millionaire-staging in /etc/logrotate.d and have been testing it by calling logrotate -f millionaire-staging. Here's my entry: #/etc/logrotate.d/millionaire-staging compress rotate 1000 dateext missingok sharedscripts copytruncate /var/www/apps/test.millionaire/log/staging.log { weekly } /var/www/apps/test.millionaire/shared/log/*log { size 40M } So, for the first folder, i want to rotate weekly (this seems to have worked fine). For the other, i want to rotate only when the log files get bigger than 40 meg. When i look in that folder (using the same locator as in the logrotate config), i can see a file in there that's 54M and which hasn't been rotated: $ ls -lh /var/www/apps/test.millionaire/shared/log/*log -rw-r--r-- 1 www-data root 33M 2010-12-29 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stderr.log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stdout.log Some of the other log files in that folder have been rotated though: $ ls -lh /var/www/apps/test.millionaire/shared/log total 91M -rw-r--r-- 1 www-data root 33M 2010-12-29 15:05 test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stderr.log -rw-r--r-- 1 deploy deploy 41K 2010-12-29 11:03 unicorn.stderr.log-20101229.gz -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stdout.log -rw-r--r-- 1 deploy deploy 1.1K 2010-10-15 11:05 unicorn.stdout.log-20101229.gz I think what might have happened is that i first ran this config with a pattern matching *.log, and that means it only rotated the two files that ended in .log (as opposed to -log). Then, when i changed the config and ran it again, it won't do any more since it think's its already had its weekly run, or something. Can anyone see what i'm doing wrong? Is it to do with those top folders being owned by root rather than deploy do you think? thanks, max
