Replace the Connections with New Connections

Replace the Connections with New Connections

If you created connections when you imported the cluster configuration, you need to replace connections in mappings with the new connections.
Perform this task in the following situation:
  • You upgraded from a version earlier than 10.2.
The method that you use to replace connections in mappings depends on the type of connection.
Hadoop connection
Run the following commands to replace the connections:
  • infacmd dis replaceMappingHadoopRuntimeConnections
    . Replaces connections associated with mappings that are deployed in applications.
  • infacmd mrs replaceMappingHadoopRuntimeConnections
    . Replaces connections associated with mappings that you run from the Developer tool.
For information about the infacmd commands, see the
Informatica Command Reference
.
Hive, HDFS, and HBase connections
You must replace the connections manually.
