RZ20, ENQ messages

[Former Member]

Hi,

I have a 3 server landscape: DB - APP1 - APP2.

DB server is in a cluster, all is running on Linux.

When running transaction RZ20 and choose "SAP CCMS Monitor Templates" " Enqueue" I see 3 entries:

• Enqueue (white color)

• Enqueue clients (green color)

• Connection to standalone enqueue (red color)

I'm puzzled about the red status of "connection to standalone enqueue"

Clicking on this item shows me the 2 appl. servers. Both are red.

clicking on the 1s appl. server shows me

• Server (white color) Standalone enqueue running on ora_sap_vip/sapdp02

• Status (red color) Network error. Could not reach standalone enqueue

• Replication Status (red color) Unknown status

The system is running fine. But I cant find anything to get this one to green.

a telnet to the servername and portname works.

resolving of the hostname works and it gets the correct server.

Anyone who can point me in some directions here?

Thanks

Looks like you are running an ASCS on a RAC cluster. By the way did you really choose ora_sap_vip as the hostname for it?

If i were you i would double check if the enqueue setup works. I always do this simple test:

call DB13 (this will set an enqueue)

check SM12 for the enqueue (you can do a 2nd call to DB13 too, you should then end up in display only mode)

The enqueue entry should be something like this:

CLIENT	USERNAME   15:46:08	E   DB6ADMLOCK	SID    22 ##########	0	1

Also try this from the other application server. Also check if these enqueue parameters are correctly setup on all instances (do not forget the ASCS instance).

rdisp/enqname

enque/process_location

enque/serverhost

enque/serverinst

Kind regards, Michael

Thx for the reply.

It's indeed a RAC cluster solution.

I will check all of those paramaters and let you know if it worked.
