清除工作流数据（Purging Workflow Data）

纵横四海

Purging Workflow DataThe Oracle Applications Manager console helps you easily maintain the Workflow database tables. Oracle Workflow accesses several tables that can grow quite large with obsolete workflow information that is stored for all completed workflow processes. The size of these tables and indexes can adversely affect performance. These tables should be purged on a regular basis, using the Purge Obsolete Workflow Runtime Data concurrent program.
Workflow PurgeThe Workflow Purge page shows summary information about the next scheduled and last completed purge requests and about completed work items.
