Jenkins job stuck running a .bat file on a remote ssh server(windows 2008 R2)

Jenkins job stuck running a .bat file on a remote ssh server(windows 2008 R2)

I have a jenkins setup running on solaris. I have configured a job which
runs a .bat file, using the jenkins ssh plugin, on a remote Windows 2008
R2 server having an oracle database. The .bat files does an RMAN restore
in the oracle Database. I have an openssh server running on Windows 2008
R2 server. When I do a restore on smaller database, which takes less than
30 mins to run, everything works fine. But when the databse is large and
the restore takes over 3 hours, the jenkins job hangs even though the rman
restore srated by the job completes successfully on the server.
This is the command I run in jenkins ssh plugin command window:
/cygdrive/C/OpenSSH/bin/SSH_ImportTEST_DB.bat TEST3
This is what the .bat file does. 1. Prepare the DB for RMAN restore(runs
few sql commands as system user) 2. Run the RMAN restore 3. Run few more
sql commands to let the Databae be availabe for all users, reset the
passwords.
Step 1 and 2 work fine but the jenkins job just shows as running step 2
even though it has completed on remote server. It never executes step 3 if
the rman restore runs over 3 hours.
X:\oracle\admin\TEST3\scripts>rman auxiliary
cmdfile=X:\oracle\admin\TEST3\scripts\restore_db2.sql
log=Y:\oracle\NightlyBackup\Prod\restore_MSIPTST3.log RMAN> 2>
This is what the restore_db2.sql contains: DUPLICATE DATABASE TO TEST3
BACKUP LOCATION 'Y:\oracle\NightlyBackup\Prod'; exit;
I have tried the restore_db2.sql without the exit command, but that
doeson't help either.
I have configured ServerAliveInterval 60 in ssh_config on the server where
jenkins is running. I have also configured ClientAliveInterval 60 in
sshd_config on the openssh server to rule out timeouts.
Can someone assit?
