SAP Note 1555955 - SAP Solution Manager 7.1 - Performance Checks for LMDB

Component : Landscape Management -

Summary :
This SAP Note addresses performance issues in SAP Solution Manager 7.1 SP01 and higher when interacting with the Landscape Management Database (LMDB). Users experiencing long response times may find that this is due to the exhaustion of server shared memory, forcing work processes to access database tables directly, prominently LMDB_P_CLASS. This is visible within TCode SM50 or SM66. A second performance issue arises when outdated Oracle database statistics slow down the initial synchronization of SLD to LMDB content, leading to increased costs for full table scans by the Cost Based Optimizer. Solutions include ensuring adequate shared memory allocation and updating Oracle database statistics periodically, particularly after starting content synchronization. Detailed guidance and links to resources for managing these settings are provided.
