About configurable process parameters
With the Load Data process parameters you are able to filter the Load Data results better, providing you with a better overview of the actual data. After selecting this parameter, you can select the instance for which you want to make changes to the default settings.
The following parameters that can be edited in AdminPoint>Warehouse Processes. Technology is the basis for the division of the process parameters:
• DB2
• J2EE
• MS .NET
• Operating System
• Oracle
• Oracle Applications
• Other
• PMDB
• SAP
• SQL Server
• Sybase
• Sybase Replication Server
• Tuxedo
• Web
• WebSphere MQ
NOTE PMDB processes will not be executed if any of the following collector instances is down: SQL Server, Oracle, Sybase, or DB2.
