[rt-users] Sqlite to MySQL migration with a 4.0.5 deployment
I see mail how to move from SQLite to MySQL with 3.x versions of RT. I expect that this may be different with 4.0.x versions. Anyone have a pointer on how to do this? I am currently running version 4.0.5. Thanks… Tim

Anyone have a pointer on how to do this? I am currently running version 4.0.5. SQLite is so liberal about datatypes and schemas are very close, so I think pretty much any SQLite - mysql converter will just work. Use the following steps: 1) install RT 4.0.5 on mysql 2) make sure it works 3) delete everything from mysql tables 4) use answers from [1] to dump tables as sql with inserts only 5) insert data mysql -u root rt4 dump.sql 6) test, adjust, repeat I think this will work, may be with tiny quircks.

[rt-users] SQLite error on new 3.8.8 Install
Hey folks, I'm running into an issue that's kind of bewildering me. I'm installing RT 3.8.8 for the first time, and I think I've done about everything needed per the ManualInstallation wiki page (and the Manual Apache Setup page following). I'm using SQLite as initial test, figuring that a compact local database would be the easiest way to evaluate RT before finding it a home on one of our primary database servers. Yes, I did pass --with-db-type=SQLite into ./configure All of the generated defaults in the RT_Config.pm have been left alone, and I haven't overridden any of the database* properties in RT_SiteConfig.pm, I'm trying to remain as vanilla as possible in this first go around. Set($DatabaseType , 'SQLite'); Set($DatabaseHost , 'localhost'); Set($DatabaseRTHost , 'localhost'); Set($DatabasePort , ''); Set($DatabaseUser , 'rt_user'); Set($DatabasePassword , 'rt_pass'); Set($DatabaseName , 'rt3'); Set($DatabaseRequireSSL , undef); Set($SenderMustExistInExternalDatabase , undef); I have set $rtname, $Organization, $Timezone, $OwnerEmail, $WebDomain, and $WebPath, and finally decided to enable DevelMode in order to try to find better error messages. I overcame a mod_perl problem already, but am now met with some sort of a SQLite error; All of the background database queries appear to be failing with an identical error message: DBD::SQLite::db prepare failed: not an error at /usr/lib/perl5/site_perl/5.8.8/DBIx/SearchBuilder/Handle.pm line 469. RT::Handle=HASH(0x2ac800384380) couldn't prepare the query 'SELECT * FROM Users WHERE lower(Name) = ?'not an error Many of those queries fail when Apache restarts, and it continues to fail each time I attempt to log in. At first, the only problem I had was being unable to log in with the initial default login, which really threw me for a loop. I just received an Authentication Failed error on the web site on log in. After diving a lot deeper, I found out that all queries to the database are failing. This is everything that I can think is pertinent; (1) Again, I haven't changed any of the RT_Config database properties. (2) The database exists at /opt/rt3/var/rt3 (3) Running the query manually via the command line sqlite3 utility works, and I see the information about the root user. (4) It goes without saying that I did indeed make initialize-database. The only error I received during that was the note about setting RTAddressRegexp, I'll set that after I can actually start working with RT. Apache: 2.2.3 Using mod_perl2 DBD::SQLite 1.29 RT 3.8.8 You can see from the error message I'm using Perl 5.8.8 (on CentOS 5.4). I don't quite know how I would trace the requests to see if it's attempting to open the database in the expected location, which is my last idea but I'm out of ways to figure it out.

SQLite is primarily intended for development and testing environments. It's not well-suited to a multi-user production environement for RT. Actually, I think SQLite's mission is to provide a lightweight database for individual use applications. It's used by a lot of such things such as Apple Mail, Safari, Firefox, Google Gears, and the Skype client. But it certainly isn't robust enough for the enterprise side of things.
