General recommendations to run InfoSphere Information Server DataStage parallel jobs on Windows Platforms

Answer

To make sure that your Windows Server is properly configured to run parallel jobs check the following list of recommendations:

• Validate that the DataStage Engine tier satisfies the system requirements for the version of the product you are using as documented in Tech Note 7042304. Note that memory requirements for each tier are cumulative if more than one tier is installed in the same machine.
• Validate that DataStage Engine tier is configured according to all recommendations documented in Tech Note 1419242
• Avoid using DataStage Clients (such as Designer, Director or Administrator) on the machine where the DataStage Engine is installed. Check Tech note 1669421 for further information on this topic.
• Avoid using Remote Desktop connections to the Engine server. Remote Desktop connections may consume the desktop heap memory and can affect DataStage. Instead of Remote Desktop connections use client machines to connect to the Engine server.
• Stop any additional service or program running in the background that is not needed for the proper functioning of the DataStage Engine machine. Even certain applications without GUI interfaces (such as print spoolers and system management tools) may consume desktop heap.
• Make sure that any anti-virus or security program follows the general recommendations for InfoSphere Information Server documented in Tech Note 1566611
