The table below lists and explains names and meanings of SAP HANA parameters. These values are tuned by editing the /etc/default/LifeKeeper configuration file.

Parameter Name Meaning Setting Value Default Value When to Apply Notes
HANA_HANDSHAKE_TAKEOVER_FAILBACK Whether to perform an automatic failback of the SAP HANA resource in the case of a failed Takeover with Handshake attempt. When set to ‘true’, LifeKeeper will automatically bring the SAP HANA resource back in-service on the previous host in the case of a failed Takeover with Handshake attempt. When set to ‘false’ (default), the SAP HANA resource remains in the Out-of-Service Failed (OSF) state after a failed Takeover with Handshake attempt and requires manual intervention to bring in-service. True or False False As required (takes effect immediately)
HANA_HSR_POLL_INTERVAL Specifies how often (in seconds) LifeKeeper will poll the status of SAP HANA System Replication. Positive integers 10 As required (takes effect immediately)
HANA_QUICKCHECK_TIMEOUT Specifies the timeout value (in seconds) for the SAP HANA quickCheck script. Positive integers, Minimum value 30 LKCHECKINTERVAL – 10 As required (takes effect immediately) If set to less than 30, it will automatically default to 30.
HANA_REGISTER_SECONDARY_DURING_RESTORE Whether the SAP HANA Recovery Kit should register and restart the secondary database before completing the in-service operation for the primary database instance. When set to ‘true’, the SAP HANA resource is not marked in-service until the recovery kit has attempted to register and restart the secondary database. When set to ‘false’ (default), the SAP HANA resource is marked in-service as soon as the primary database instance is running, and a local recovery event is initiated immediately afterward to register and restart the secondary database. True or False False As required (takes effect immediately)
HANA_RECOVER_TIMEOUT Specifies the timeout value (in seconds) for the SAP HANA recover script. Positive integers 1800 As required (takes effect immediately)
