  2. Introduce SSH_SKIP_OUTPUT_LINES to the DDC file, by setting this parameter to a number value, that number of lines will be ignored during ssh connections.  Example if your ssh banner is 5 lines, you can specify SSH_SKIP_OUTPUT_LINES=5 and the first 5 lines of ssh output (which will include the banner) will be skipped



  1. During CSD, the standby controlfile and pfile was deleted before being transferred to standby when the direct copy option was selected and a CSD process was restarted - fixed
  2. Internal repository table DBV_TRANSFER_LOG index extended to include ORACLE_SID_DEST this is to improve handling of multiple standby databases - A Repository upgrade should be performed with this release. Internal repository version is now 6.2

  1. During Activation of a standby database a new "nosynch" option can be passed to the activation process which will set the _COPY_TO_REMOTE and SYNCH_DBVISIT_INSTALL to "No" in the newly Activated database DDC File.  This will ensure that even if a schedule is running, the newly Activated database's DDC file will not be coppied back to the original primary server.  This is useful to ensure the original primary DDC file stays in tact if the Activition is done while the original primary is still available.
  2. Allow the configuration (setup) of Dbvisit Standby to continue if the software owner account does not exist on the local system.  This option is to allow for the use of LDAP or other external user management and authentication.

  5. Improved code around the use of APPLY_READ_ONLY.  If set to Y (yes) the database will return to recovery mode if it was opened read only. Default value is N (no).


6.0.38 - (22 Sep 2012)

  1. Removed blank spaces from HOSTNAME_CMD return value.
  2. Improved process for retrieving recovery SCN without running a recovery session on standby. This new method will ensure that the log gap report does not interfere with the apply process on the standby.  To switch to old functionality set FORCE_RECOVERY_SESSION = Y (default N).
  3. Datafiles can now be added to the standby database without recreating of the standby control file. To switch to old functionality set FORCE_RECREATE_STANDBY_CTL = Y (default N).

  3. Allow one-way communication of Dbvisit Standby from primary to standby for ultra secure configurations which only allow one-way traffic. Set BLIND=Y to enforce this, but there is reduced Dbvisit Standby functionality (no checkums, no log gap reporting, no Resync and no creation of standby database options available).


  1. Dbvisit Standby could not cope with Oracle reserved words used for tablespace names in SQL statements (like INDEX) - fixed.
  2. Dbvisit Standby restarted a database in restricted mode during shutdown that potentially lead to generating extra archive logs and issues during graceful switchover - fixed.
  3. Global variable LOGDIR set to value of LOGDIR_DR on the standby server.
  4. Queries of dictionary tables called by ora_list_dictionary function altered to format the display of checkpoint_change#.
