Reason for change
There are no functional changes in this release, it only includes a few performance enhancements implemented during testing
of the new oracle database. In addition we will reconfigure the mail delivery from batch jobs to go via glast's own SMTP mail server instead of SLAC's exchange server, to reduce the load on exchange and isolate us from any exchange problems/outages.
It would be good to get these changes in before the L1 stress testing starts as they may impact performance (hopefully for the better).
Test Procedure
These changes have all been extensively tested in the TEST and DEV pipeline's.
Rollback procedure
Any of these changes can quickly and easily be backed out should unanticipated problems appear when the code is moved to production. Backing out the e-mail delivery change will need to be coordinated with Teresa Downey in SCCS, but can be done with one hour's notice.
