  2. Contents Command Line Options Caching Logging Error Handling

  3. PSP Command Line Options • Options (subset) • calc - Calculate provisioning for an identifier. • diff - Determine provisioning difference for an identifier. • sync - Synchronize provisioning for an identifier. • bulkCalc - Calculate provisioning for all identifiers. • bulkDiff - Determine provisioning difference for all identifiers. • bulkSync - Synchronize provisioning for all identifiers. • Demo

  4. PSP Caching • Caching adjustments in ehcache.xml are critical for performance especially for bulk provisioning. • Avoid repeated subject queries by tuning cache settings for: • edu.internet2.middleware.grouper.subj.CachingResolver.Find • edu.internet2.middleware.grouper.subj.CachingResolver.FindAll • edu.internet2.middleware.grouper.subj.CachingResolver.FindPage • edu.internet2.middleware.grouper.subj.CachingResolver.FindByIdentifier • edu.internet2.middleware.grouper.subj.CachingResolver.FindByIdOrIdentifier • maxElementsInMemory should be equal to or greater than the number of subjects that you have. • timeToIdleSecondsand timeToLiveSeconds are ideally set to the amount of time it takes the bulk provisioning to run.

  5. PSP Logging • Logging is controlled via log4j.properties. • Default logging: # Provisioning : PSP (version 2.1+) log4j.logger.edu.internet2.middleware.psp = INFO # Provisioning : vt-ldap # log4j.logger.edu.vt.middleware.ldap = INFO # Provisioning : Grouper plugin to Shibboleth attribute resolver # log4j.logger.edu.internet2.middleware.grouper.shibboleth = INFO

  6. PSP Error Handling • Incremental provisioning • Error handling is controlled by a property in grouper-loader.properties: changeLog.consumer.psp.retryOnError • true: If an error occurs on a change log event, continue to retry it until it succeeds. • false: If an error occurs on a change log event, ignore the failure and move on to the next change. This assumes that the bulk provisioning job will eventually correct the failure. • Grouper report will indicate failures. • Grouper diagnostics will also report errors if the PSP incremental job has not had a success in the last 30 minutes. • Bulk Provisioning • By default, PSP will resume on errors.
