Consider the following rules and guidelines and understand the limitations before you create TDM services in a multinode setup:
Installation and Upgrade
When you create a Test Data Manager Service on a node that is not a gateway node, it is recommended to retain the default Test Data Manager Server Configuration settings and the Advanced Properties.
Configuration
The PowerCenter Integration Service creates temporary cache files on the node where you run a TDM workflow. The cache files must be available to the PowerCenter Integration Service for the workflow to run. If you configure the Test Data Manager Service and the PowerCenter Integration Service on different nodes, you must configure the TDM cache directory inside an
infa_shared
directory. The
infa_shared
directory must be accessible to all nodes that the Test Data Manager Service and the PowerCenter Integration Service use. Configure the TDM cache directory from the
Workflow Generation
tab in the
Administrator | Preferences
view in Test Data Manager.
Configure a different cache directory within the
infa_shared
directory for each node on which you create a Test Data Manager Service. TDM generates temporary folders with the plan name in the cache directory. The plan names might conflict with plans created on other nodes.
If you install Informatica services in a different directory structure on each node on Windows, create a soft link on the node with the PowerCenter Integration Service. The soft link must allow the node with the PowerCenter Integration Service to access the cache folder on the node that generates the workflow.
If you install Informatica services in a different directory structure on each node on Linux, you must mount the directories. Users must have read, write, and execute permission on the mounted directories.
After you create the Test Data Manager Service, log in to Test Data Manager and verify the default staging connection on each node. You must use different connection names on each node. Use the default TDM_CONNECTION only on one node.
Connection Sharing
Multiple nodes can connect to a single Model Repository Service, but the connections are not shared across the nodes. Changes to connections on one node do not impact other nodes.
Restrictions
The Test Data Manager Service cannot connect to a PowerCenter Integration Service or a Data Integration Service that runs on a grid.
Failover and recovery are not available with the Test Data Manager Service.
