Metadata Manager
This section describes release tasks for Metadata Manager in version 10.1.1.
Business Intelligence Resources
Effective in version 10.1.1, the Worker Threads configuration property for some Business Intelligence resources is replaced with the Multiple Threads configuration property. If you set the Worker Threads property in the previous version of Metadata Manager, set the Multiple Threads property to the same value after you upgrade.
Update the value of the Multiple Threads property for the following resources:
- •Business Objects
- •Cognos
- •Oracle Business Intelligence Enterprise Edition
- •Tableau
The Multiple Threads configuration property controls the number of worker threads that the Metadata Manager Agent uses to extract metadata asynchronously. If you do not update the Multiple Threads property after upgrade, the Metadata Manager Agent calculates the number of worker threads. The Metadata Manager Agent allocates between one and six threads based on the JVM architecture and the number of available CPU cores on the machine that runs the Metadata Manager Agent.
For more information about the Multiple Threads configuration property, see the "Business Intelligence Resources" chapter in the Informatica 10.1.1 Metadata Manager Administrator Guide.
Cloudera Navigator Resources
Effective in version 10.1, you must configure the Java heap size for the Cloudera Navigator server and the maximum heap size for the Metadata Manager Service. If you do not correctly configure the heap sizes, the metadata load can fail.
Set the Java heap size for the Cloudera Navigator Server to at least 2 GB. If the heap size is not sufficient, the resource load fails with a connection refused error.
Set the maximum heap size for the Metadata Manager Service to at least 4 GB. If you perform simultaneous resource loads, increase the maximum heap size by at least 1 GB for each resource load. For example, to load two Cloudera Navigator resources simultaneously, increase the maximum heap size by 2 GB. Therefore, you would set the Max Heap Size property for the Metadata Manager Service to at least 6144 MB (6 GB). If the maximum heap size is not sufficient, the load fails with an out of memory error.
For more information about Cloudera Navigator resources, see the "Database Management Resources" chapter in the Informatica 10.1.1 Metadata Manager Administrator Guide.
Tableau Resources
Effective in version 10.1.1, the Tableau model has minor changes. Therefore, you must purge and reload Tableau resources after you upgrade.
For more information about Tableau resources, see the "Business Intelligence Resources" chapter in the Informatica 10.1.1 Metadata Manager Administrator Guide.
