Rational Programming Patterns

Modifying parameters to import large databases

You must modify two types of parameters to import large databases.

Memory parameter

You must modify the memory parameter of the Software Delivery Platform. Its maximum value varies according to the operating system and the memory available. You must then find the maximum value for your configuration.

To do so, edit the eclipse.ini file that is located directly under the root of your Software Delivery Platform.

The Java™ heap size is set to 1024 by default (in -Xmx1024m). You can increase this value to adapt it to your configuration.
Note: for an installation in 32-bit mode, the maximum value if 1.5 gigabyte.

Property of the Rational Team Concert server

You must also modify one of the advanced properties of the Rational Team Concert server.
  1. Log in as an administrator to https://[fully-qualified hostname]:9443/ccm/admin.
  2. In the Configuration entry, click Advanced properties.
  3. Scroll the properties down to the Soruce code data collection category. This category contains the line com.ibm.team.enterprise.internal.metadata.collection.service.MetadataCollectionService.
  4. Change the value of the property Max. number of files in source code data resource. Click its current value and enter 100 instead.

DB2 parameter

To run Rational Team Concert™ with a DB2® database, you can see the jazz.net site for information about the DB2 tuning. To import large DB2 databases, you must increase the following values:
db2 UPDATE DB CFG FOR CCM using LOGPRIMARY 100
db2 UPDATE DB CFG FOR CCM using LOGSECOND 100
where 100 is the increased value. To see the values, use the following command: :
db2 GET DB CFG FOR sample |grep '(LOG[FPS]'
You obtain the following values:
 Size of journal files (4 Kb)      (LOGFILSIZ) = 1000
 Number of primary journal files   (LOGPRIMARY) = 3
 Number of secondary journal files (LOGSECOND)  = 2
