The tunable parameters shown in Table 127, Table 128, and Table 129 control failover detection. By default, these parameters are set so that failover occurs in less than one minute. You may need to fine tune these parameters based on your business requirements.
Table 127. Tunable Agent Parameters (in essbase.cfg)
Agent Parameter | Value |
---|---|
Agent Lease Expiry Time | 20 seconds |
Agent Lease Renewal Interval | 10 seconds |
Agent Lease Acquire Max Retry | 5 |
Table 128. Tunable Server Parameters (in essbase.cfg)
Server Parameter | Value |
---|---|
Server Lease Expiry Time | 20 seconds |
Server Lease Renewal Interval | 10 seconds |
Server Lease Acquire Max Retry | 5 |
The time delay between each lease acquire failed attempt until maximum retry is calculated based on how much time is left for the lease to expire. If the lease is available and acquire fails, then the delay could be one second. See Oracle Essbase Technical Reference.
Table 129. Tunable OPMN Parameters (in opmn.xml)
OPMN Parameter | Default Value |
---|---|
restart-on-death | FALSE. If FAILOVERMODE is set to TRUE (in essbase.cfg), you must change this value to TRUE so that OPMN restarts Essbase Agent if it terminates abnormally. |
shutdown-force-enabled | FALSE. You must set this to TRUE if you enabled Essbase failover clustering. Setting this to TRUE enables you to forcibly kill Essbase if graceful shutdown by OPMN fails. |
OPMN Forward Ping Interval | 20 seconds |
OPMN PROC_READY (reverse ping) Interval | 20 seconds |
Agent Start or Restart Retries | 2 This means that OPMN tolerates two failures to start or restart the agent before marking this instance as nonfunctional for this service, which is when the agent service failover begins in failover mode; otherwise it will throw an error. |
OPMN Agent Start Timeout | 10 minutes |
OPMN Agent Restart Timeout | 10 minutes |
OPMN Agent Stop Timeout | 10 minutes |
