Enqueue Work Process in HA Environment

Former Member

Dear gurus,

I'm having doubt about the enqueue wp like this:

When SAP environment is running normally, that is, node 1 (CIDBASCS) and node 2 (apps) are up and running, enqueue WP is set in CI (one enqueue WP), while enqueue WP in node 2 is 0.

When Node 1 down, only DB package move to node 2.

What I confuse is, if node 2 (apps) doesn't have enqueue WP set in the first place, how will the enqueue be handled then if I start SAP on node 2?

As far as I know, the CI is not configured to be a moveable package (static).

Is enqueue WP is not needed if you've already running ASCS?

Thanks for help.

Regards,

In HA, you use standalone enqueue + ERS replication for failover scenario. So, forget about enqueue wp.

Those CI and other dialog instance will behave like enqueue client, and should have setting:

enque/process_location = REMOTESA

enque/serverhost = <host name of the enqueue server>

enque/serverinst = <instance number of the enqueue server>

Hi,

Enqueue server runs in ASCS instance. So, if your node1 will be down then ASCS will be on node 2 where Enqueue service will be running.

Thanks
