perhaps opposite to one jira - two databases I read, which commented by @Nic Brough [Adaptavist]
my question :
one database serving two jira instances would cause disaster ? dbconfig.xml will be same on the database connection, I think, so wonder is it possible I run jira 1 on one machine to access database 1, then I install jira 2, still point out to database 1 ? what would be happening ?
kind of reminding one servant two masters, but not at the same time :-D
Due to limited source, I only get one database for testing, so I wonder 'recycling' , however, should I contact DBA to wrap out whole database before I config it in another jira ?
For older versions of Jira, yes, it was a disaster. Both of them would be unable to write issues correctly and their indexes fail rapidly. If you left them long enough, with active users, you'd get a completely corrupt database.
Newer versions of Jira try to prevent the corruption - the first one to connect writes a record into a table which tells other installations that the database is in use, so they just shut down with an error saying the database is already in use by a previous Jira.
