SGeSAP: Problems configuring ASCS

[Nick Stocker]

I am setting up a ServiceGuard package which is using DVEBMGS AND ASCS but the ASCS is not being used for replicated emqueue. The enqueue in our case is part of the DVEBMGS. We also have the DB and CI together in one package.

When looking at the Manual and sap.config it tells you to configure the CINAME to be DVEBMGS OR ASCS. I have set this to DVEBMGS as that is the one which has the central instance.

It doesn't seem to tell you how to configure in an ASCS as well as a DVEBMGS if you want both without having the ASCS in a separate package.

I have tried putting a separate startsap command for the ASCS in the customer_defined_run_commands and that does start it but the package falls over due to a communication problem from the dispatcher. I feel that rather than forcing it to start the ASCS in this way it should be configured in properly so the extensions handles is.

Has anyone got any ideas how this should be done properly?

Cheers
Nick.

If you have an ASCS this is the central instance (therefore the CINAME is set to ASCS). In such a setup DVEBMGS is usually the name of the first application server (although I never understood why they could not simply stick to consistent and reasonable naming convention) and should be put under DNAME[0].

The enqueue should really be part of the ASCS.

I have actually tried that

e.g.

CINAME=ASCS
CINR=30
CIRELOC=[virtual ip address of package]

but I am still hitting problems. It comes up for so long then the dispatcher monitor spots a problem and shuts the package down. I am getting this error:

(dispmon_monitor): ERROR: No handshake possible - dispatcher process of DVEBMGS00 locked or no communication possible

Incidentally I was also having problems as the IP address I used mapped to a hostname in the /etc/hosts file which didn't correspond with a profile name of the ASCS. I corrected that so it did start up but I am left wondering what this handshake problem is caused by. Any ideas?
