It looks like derby database is corrupt, and it is causing critical problem in our e derby.log <http://apache-database.10148.n7.nabble.com/file/n143610/derby.log> nd with the huge business impact. And the path which its saying derby not found is valid and correct path . Still why suddenly derby got corrputed and what are the reasons for the corruption ?
There are various possibilities: 1) You experienced a hard-disk failure on the disk holding /usr/ironhide/var/db 2) or, you experienced a power-failure which caused the operating system to write incorrect data to the filesystem, or fail to flush its buffers properly, perhaps because write-caching was enabled on the filesystem hardware 3) or, you filled up the filesystem /usr/ironhide/var/db, and all the databases and their redo logs were on the same filesystem and all were damaged simultaneously 4) or, some other piece of software, not Derby, wrote updates to the Derby files directly There are certainly other possibilities. Have you inspected your system logs and talked to your system administrators for more information about what was going on at the moment that you noticed the problems? Do you have backups of these databases? Can you print the *full* exception logs from your attempts to access the databases (http://wiki.apache.org/db-derby/UnwindExceptionChain) thanks, bryan
