Store High Availability Persistence on a Cluster File System
By default, the PowerCenter Integration Service stores process state information along with the state of operation files in the $PMStorageDir directory of the Integration Service process. You must configure the $PMStorageDir directory for each PowerCenter Integration Service process to use the same directory on a cluster file system.
Nodes that run the PowerCenter Integration Service must be on the same cluster file system so that they can share resources. Also, nodes within a cluster must be on the cluster file system’s heartbeat network. Use a highly available cluster file system that is configured for I/O fencing. The hardware requirements and configuration of an I/O fencing solution are different for each file system.
The following cluster file systems are certified by Informatica for use for PowerCenter Integration Service failover and session recovery:
Storage Array Network
Veritas Cluster Files System (VxFS)
IBM General Parallel File System (GPFS)
Network Attached Storage using NFS v3 protocol
EMC UxFS hosted on an EMV Celerra NAS appliance
NetApp WAFL hosted on a NetApp NAS appliance
