Hi experts,

I am getting the following error when i run ensmon for Java SCS Instance on SLES 10.

ep3adm@vcslinux245:~> ensmon pf=/usr/sap/EP3/SYS/profile/EP3_SCS04_sapep4scs 2

Try to connect to host service sapdp04

could not create connection to enqueue server

ep3adm@vcslinux245:~> echo $?

Also when I run the command for ABAP SCS or ABAP+Java (A)SCS i am not getting the error.

Here is the dev_ensmon output for the command.

Any help will be appreciated.

Dear Venkat,

the last line before the error messages in the dev-trace looks like the essential line. It sais: "EncCliCon:hostname unknown". The ensmon needs to know on which host the enqueue server is running on. This is told any C enqueue client by the profile parameter enque/serverhost (java clients get this information differently). Usually the enque/serverhost parameter is not set in the SCS/ASCS profile as the server does not need to know where it is running (it has other wais to determine that anyway), but if your start ensmon with the profile of an SCS then your have to add this profile parameter to the profile.

Hope I could help you.

Regards,

Jens
