Finally, after much procrastination, the dbreplicator project has released its first public version. This enables mult-master database replication between a variety of RDBMS's, and contains many performance enhancements over its predecessor. Key improvements include improved conflict handling, improved memory handling resulting in reduced memory requirements, faster sync and snapshots, cleanup of old shadow records, proper handling of columns with special characters, fixes to update trigger creation, a linux server mode (starting dbreplicator as a service) and debian packaging. For a complete listing of changes, see the <a href=node/33>changelogs</a>. Some things to note: DBReplicator requires a Java Runtime Environment (JRE), and has only been tested on Sun's version. It has been tested with both Java5 (1.5.x) and Java6, and although it runs perfectly on both, it will only compile on Java5 due to some code which has been deprecated. Something to keep in mind if you're downloading the source or recompiling. Downloading is presently through sourceforge, the link to which is located <a href=downloads>here</a>. I haven't tested trigger/function creation on all supported databases, so if you're having issues with a particular database, the first thing to examine is the triggers that were created on your replicated table. You should have three (insert/update/delete) for each. If you don't, submit a bug report through the sourceforge page, or post to the forum here and we should get it resolved quickly. As always, comments, suggestions or criticisms are always welcome. Brian |
