Configuring Service Process Variables for Multiple Nodes
Configuring Service Process Variables for Multiple Nodes
When you configure the PowerCenter Integration Service to run on a grid or a backup node, all PowerCenter Integration Service processes associated with a PowerCenter Integration Service must use the same shared directories for PowerCenter Integration Service files.
Configure service process variables with identical absolute paths to the shared directories on each node that is configured to run the PowerCenter Integration Service. If you use a mounted drive or a mapped drive, the absolute path to the shared location must also be identical.
For example, if you have a primary and a backup node for the PowerCenter Integration Service, recovery fails when nodes use the following drives for the storage directory:
Mapped drive on node1: F:\shared\Informatica\<infa_version>\infa_shared\Storage
Mapped drive on node2: G:\shared\Informatica\<infa_version>\infa_shared\Storage
Recovery also fails when nodes use the following drives for the storage directory:
Mounted drive on node1: /mnt/shared/Informatica/<infa_version>/infa_shared/Storage
Mounted drive on node2: /mnt/shared_filesystem/Informatica/<infa_version>/infa_shared/Storage
To use the mapped or mounted drives successfully, both nodes must use the same drive.
