Rules and Guidelines for Grids that Run Jobs in Remote Mode
Consider the following rules and guidelines when you configure a Data Integration Service grid to run jobs in separate remote processes:
The grid must contain at least one node with both the service and compute roles to run an ad hoc job, with the exception of profiles. The Data Integration Service runs these job types in a separate DTM process on the local node. Add additional nodes with both the service and compute roles so that these job types can be distributed to service processes running on other nodes in the grid.
To support failover for the Data Integration Service, the grid must contain at least two nodes that have the service role.
If you associate a Content Management Service with the Data Integration Service to run mappings that read reference data, each node in the grid must have both the service and compute roles.
The grid cannot include two nodes that are defined on the same host machine.
Informatica does not recommend assigning multiple Data Integration Services to the same grid nor assigning one node to multiple Data Integration Service grids.
If a worker compute node is shared across multiple grids, mappings dispatched to the node might fail due to an over allocation of the node's resources. If a master compute node is shared across multiple grids, the log events for the master compute node are also shared and might become difficult to troubleshoot.
