Hello HA Gurus...
We are setting a sandbox system in HA mode to demonstrate that the
users can preserve their transactions context even when we have to
restart the ASCS instance, either on the same Host or on the second host.
On HostA we have installed ERP2006 SR3:
On HostB we have installed:
Before doing interuption, the ensmon shows that the ERS is
properly connected to the SCS:
Try to connect to host vsrs9scs service sapdp10
get replinfo request executed successfully
Replication is enabled in server, repl. server is connected
Replication is active
When we perform a restart of the ASCS10 instance, even if the user sessions are kept,
the transactions are reset. On the ERS11 work directory, the
file dev_enrepsrv indicates the following error message when ASCS10 restarts:
Reconnect: repl. table layout has changed, delete old one
And in fact, the number of entries in the replicated enqueue servers
are reset to 0 and the transactions are reset.
On ERS hosts:
trc file: "dev_eq_trc_856194", trc level: 1, release: "700"
