Introduction


As stated quite often, IT management and application lifecycle management won't work without data in System Landscape Directory and SAP Solution Manager Landscape Management Database (LMDB). Use, topology, and many specific scenarios have been described on three pages containing multiple documents and blogs - but you may be interested in "rules of thumb" plus related blogs and notes regarding specific aspects of handling these applications...

Rules of Thumb, Notes, and Blogs (a Summary)




Figure 1: A simplified landscape with some examples of tasks and actions required to run and use SLD and LMDB.

SLD/LMDB Setup


Use a central SLD for system registration


Distribute system registrations to any secondary SLD via bridge forwarding

Use (virtual) host names being stable over time as much as possible



Enhance SLD data supplier processing for system landscape changes – see



Set up a procedure to update CR Content in all SLD system regularly



Avoid using multiple source SLD systems for LMDB



If using PI monitoring for multiple PI domains, do not use a PI SLD as source SLD for LMDB



Consider a separate SLD as source SLD for LMDB



Setup agents on technical systems and connect the to the LMDB



Configure the system upload to SMP in one SAP Solution Manager only



  • For details, see http://help.sap.com/solutionmanager71 –> Application Help –> English –> SAP Solution Manager Operations –> Managing System Landscape Information –> Setting Up the Landscape Management Infrastructure –> Synchronizing with SAP Support Portal



SLD/LMDB Change Management


Change the source SLD with care



Set up a copied LMDB with care



Avoid synchronization conflicts



Use the automation potential in SLD and LMDB



Avoid host name changes in any system profiles



Integrate SLD and LMDB in your system lifecycle management processes


Avoid manual changes in LMDB and SLD



  • Adding information which is not available in the systems is O.K.

  • Repairing information which is wrong in the systems is NOT O.K.

  • Consider the proper directory for the change (SLD or LMDB) – change data, where they are "original"

  • For automation options, see SAP note 1916052 - Automation in landscape management


SLD/LMDB Operations


Clean up SLD and LMDB once a year



Update CR Content in all SLD systems every quarter



Check status in transaction LMDB_ADM every week



  • At least error messages shall be solved
