Replication Server Data Assurance Option 15.7.1 allows you to recover the da_admin password for DA server or DA agent.
To recover the da_admin password:
%SYBASE%\DA-15_5\server\instance\RUN_instance_32.bat -P
%SYBASE%\DA-15_5\server\instance\RUN_instance_64.bat -P
$SYBASE/DA-15_5/server/instance/RUN_instance_64.sh -P
%SYBASE%\DA-15_5\agent\instance\RUN_instance_32.bat -P
%SYBASE%\DA-15_5\agent\instance\RUN_instance_64.bat -P
$SYBASE/DA-15_5/agent/instance/RUN_instance_64.sh -P
where -P is the password recovery start-up parameter and instance is the name of your DA server or DA agent.
On start-up, the DA server or the DA agent generates a new da_admin password, which is written to the DA server or DA agent log file found either at:
$SYBASE/DA_15-5/server/instance/log/da_0.log
or
$SYBASE/DA_15-5/agent/instance/log/da_0.log
