Our production system is a cluster environment.
ASCS + DB in Node 0
ERS in node 1
2 Standalone dialog instance application is running in each server.
Checkdb is working fine without any error in the above condition
But, If we moved the ASCS and DB from Node 0 to Node 1 (during Failover), we are getting the following error in Checkdb(db13) " SXPG_COMMAND_EXECUTE failed for BRCONNECT - Reason: program_start_error: For More Information, See SYS"
Also SAPXPG_DBDEST_hostDB RFC in node 1 is working fine and but in node 0 its throwing an error.
SAPXPG_DBDEST_hostDB RFC is working fine in node1 (where DB is available)
SAPXPG_DBDEST_hostDB RFC is not working fine in node0 (where DB is not available)
We set the below parameter
SAPDBHOST = virtual hostname of DB
gw/netstat_once to 0
DBACOCKPIT -> "Jobs" -> "Backend Konfiguration" -Menü -> "Administration" -> ORACLE-Settings set to virtual hostname of DB
AIX : 7.1
DB : Oracle 220.127.116.11
SAP : SAP NW 7.5
