We are having same issue, we have upgraded from 4.2.2 to 4.2.3
DB - Oracle
Error -
java.sql.SQLException: ConnectionManager.getConnection() failed to obtain a connection after 11 retries. The exception from the last attempt is as follows: java.sql.SQLException: Check JDBC properties; data source was not be initialised
Hi @wroot
issue resolved.
oracle jdbc jar file was not there in lib folder after upgrade.
we copied ojdbc jar file(from backup) to lib folder then it was working fine.
Please raise this as bug. Thank you for usual support.
I have filed https://issues.igniterealtime.org/browse/OF-1757 to investigate this. But i suspect you are using Oracle DB version not supported by included connectors. Especially if you had to also add it manually for older 4.2.3 version.
