Runtime Maintenance Cleanup

An important part of maintaining system health is periodically cleaning up the runtime environment. Over time, runtime artifacts accumulate and can impact system performance.

Sybase Unwired Platform lets the SUP Administrator and SUP Domain Administrator automate cleanup of accumulated data items at the domain level. Types of data that are eligible for cleanup include: synchronization cache, online cache, client log, error history, and subscriptions.

Set up a schedule for each of these categories, so the clean up processes run when system usage is low. You can also manually purge accumulated data items at any time. You can use the Administration API to automate clean up at the package level.

Sybase also recommends manual cluster-level cleanup for unused devices and users.

• Scheduling Domain-Level Cleanup
  Periodically clean up accumulated data maintenance items in cache that are no longer needed.
• Purging Unused Devices
  Periodically clean up devices not used since a given date. This purges device associated items such as subscriptions.
• Purging Unused Device Users
  Periodically clean up users. User cleanup removes any user-specific data stored in the consolidated database, such as personalization keys. If you remove a security configuration, all users registered with that security configuration are also removed.
• Maintaining Platform Databases
  Platform databases need to be rebuilt regularly. Without regular maintenance, the database log can grow to be large (several gigabytes in size), and performance could degrade.
