Starting external progran SAPXPG failed (SM69)

Question

System Information:
ECC 6, Oracle 10.2, AIX 5.3, Kernel Patch level 147
Hi all,
We were encountered problems when try to scheduled actions in DB13.
We had install CI & DB on separate server and the rfc SAPXPG_DBDEST_<Destination> is not working.
We tried to use RSH in SM49/SM69 to start external program SAPXPG in target host remotely, however, it return External program terminated with exit code 1 when we executed it.
*External command we used
Rsh
Target host u2013l <sid>adm sapxpg

We couldnu2019t located any clear error indication that might help us in troubleshooting.
We already configured settings in .rhosts file & we had resolve the permission problem
We executed the following commands as user <sid>adm:
In DB host, we executed rsh <CI host> date & it works.
But in DB hosts, its doesn't work when we executed rsh <DB host> date
Is this issue should be isolated as AIX OS issue?
We couldn't execute any activities from DB13 as the DB rfc destination is not working.
Is that alternative way that we can execute sapxpg on DB host?
Or we have to install standalone gateway as solution? It's that any impact if we installing standalone gateway at DB host now (It's production system)?
Thanks.

Answer 1

Hi Guru,
When we tried to execute the following command from host DB:
rsh <Host CI> date
it was return results.
However, if we tried to execute from host CI:
rsh <Host DB> data
it was return no results.
That's means we could'nt remotely start any of external command at DB host from CI host.
Start external program error was isolated within operating system level.
Any luck on this?
Thanks.
BR,
Terry
