Issue:

     We noticed slowness in accessing portal and when we try to connect to registry from workstation it is taking long time in accessing registry. We verified the service behavior throw windows taskmanager and Registry service is running continuously with more than 100% usage. 

Environment:
Windows 2008Registry is connected to default database.
Resolution:
  • Please verify db ping time in registry.log file. If db ping time is high (more than 500 ms) , registry will respond slow. Verify the connectivity between registry service and database.
  • Also check memory usage in registry.log file. If used memory is high, check the memory settings for the components.
  • Since the registry is running with default derby database, verify the size of database from <Devtest_home>/database/lisa.db folder. If the size of this folder is huge, recreate the database by taking backup of existing folder and restart the registry (or) use external database for better performance.
