The DTM process does not create DTM log files for mappings included in workflow Mapping tasks when the following conditions are true:

The Data Integration Service is configured to run jobs in separate remote processes.
The mapping included in the workflow Mapping task uses multibyte characters.

If you run multiple concurrent mappings on a Data Integration Service grid configured to run jobs in separate remote processes and the Model repository is not configured to store run-time statistics, some of the mappings might fail to run with the following error:

[ICMD_10033] Command [runmapping] failed with error [com.informatica.ds.ms.service.MonitorHelper.purgeStatistics(MonitorHelper.java:125)

The consolidated log file for a mapping might contain the incorrect DTM log file when the following conditions are true:

The Data Integration Service is configured to run jobs in separate remote processes.
The Mapping task in a workflow is configured to save the Mapping task log file by the number of Mapping task runs.

Mappings run on a Data Integration Service grid might hang indefinitely when the following conditions are true:

The Data Integration Service is configured to run jobs in separate remote processes.
The Resource Manager Service becomes unavailable after the Data Integration Service has been enabled and has elected a master compute node.

When you update the compute role on a node assigned to a Data Integration Service grid and then recycle the Data Integration Service, you might encounter inconsistent behavior across the Informatica client tools. For example, mappings might fail to run in the infacmd command line program but succeed in the Developer tool.

In a Kerberos domain, mappings fail to run on a Data Integration Service grid configured to run jobs in separate remote processes.

A Data Integration Service grid configured to run jobs in separate remote processes does not use a secure connection to communicate with remote DTM processes even though the domain is enabled for secure communication. (432752)

The Processes tab of the Email Service includes an environment variable section even though environment variables are not supported for the Email Service. If you add an enviornment variable, the Email Service ignores it. (442102)

If you run web service requests on a Data Integration Service grid and you incorrectly configure the external HTTP load balancer to use nodes with the service role only, the Data Integration Service does not redirect requests to nodes with both the service and compute roles. Some web service requests dispatched to the node with the service role only might fail.

When you run a mapping on a Data Integration Service grid configured to run jobs in separate remote processes, the Monitor tab of the Administrator tool might indefinitely list the mapping state as Running even though the infacmd command line program and the mapping log indicate that the mapping failed.
