• Edit .current file in your test release to point it to existing release (NB make sure you use the same major number, e.g. 6.10.8 for 6-series, 7.3.1 for 7-series):

  yury@percheron$ cat .current
  7.2.2
  

• Execute srtpath and setboot, e.g.:

  yury@percheron$ srtpath
  enter release number (CR=7.2.2):
   
  set BFCURRENT to 7.2.2
  enter BFARCH (CR=SunOS5):
   
  set BFARCH to SunOS5
  removing other SRT bin directories from PATH
  adding ./bin/SunOS5 and $BFDIST/7.2.2/bin/SunOS5 to PATH.
  yury@percheron$ setboot
  OO_FD_BOOT set to /nfs/objyserv2/u4/databases/yury/7.2.2/BaBar.BOOT
  

  These commands set your environment to use the correct version of Objectivity.
• Delete the database using command:
  

  oodeletefd <path_to_your_boot_file>
  where <path_to_your_boot_file> should point to the database your are deleting, e.g.

  yury@percheron$ oodeletefd /nfs/objyserv2/u3/databases/${USER}/7.0.1/BaBar.BOOT
  

  for an old 7.0.1 database.

ANOTHER USEFUL TIP:
After deleting the DB with the standard commands, the top level directory may be left behind, e.g.

/nfs/objyserv2/u4/databases/young/6.10.9/

It is safe and indeed a good house-keeping habit to remove this directory provided these two files are not there:

BaBar.BOOT
    BaBar.FDB
