Use the gc_shutdown.sh script to gracefully shutdown all configured user applications and associated Assure MIMIX DR for AIX replication groups on both nodes configured in an Assure MIMIX for AIX clustered environment, and stop cluster services on the node where the AIX shutdown command is executed. This script creates a log file /usr/EchoCluster/log/gc_shutdown.sh.out.
The gc_shutdown.sh script uses the dynamically tunable parameter APPLICATION_STOP_GRACETIME located in the file /usr/EchoCluster/etc/node_config.properties. The parameter is set with a default limit of 600000 milliseconds (10 minutes). If stopping any of your applications exceed these limits, the AIX shutdown will be aborted and the application stop process will continue until the application is completely stopped.
