Description of problem:
Add all databaze specific Quartz delegate jars to engine libs. See Maciej's comment why is this necessary:

Because Quartz specific jars are necessary, as explained above, I propose this issue as a 6.1 blocker.
Version-Release number of selected component (if applicable):
BPM Suite 6.1.0.ER6
Only quartz-oracle-1.8.5.jar has been added as a result of fixing BZ1153343.
Quartz delegate jars for all databases are part of the BPM Suite.
the only missing delegates are:
all other delegates are part of regular quartz jar file so there is no need to add them into the distribution, simply because there is nothing to add.
If we agree then quartz-weblogic.jar could be added in there.
For docs, I think we should add to the docs that, when using Oracle, it is recommended to use the oracle delegate for quartz:
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.oracle.OracleDelegate
Quartz jars located in engine libs:
- quartz-1.8.5.jar - as Maciej stated, contains delegates for all DBs except Oracle.
- quartz-weblogic-1.8.5.jar - delegates for Weblogic.
- quartz-oracle-1.8.5.jar - delegates for Oracle.
