Resynchronizing Technical System Information from SLD

It can be required to restore technical system descriptions from the System Landscape Directory (SLD), for the following reasons:

The system description was changed or created manually in the landscape management database (LMDB) and you now want to reset it with the information from the SLD.
Different SLDs created inconsistent system descriptions in the LMDB. If the data in the SLDs differs (for example, because one SLD receives information from a data supplier and one by manual data import), LMDB data can be inconsistent. For more information, see Managing System Landscape Information.
You deleted the system in the LMDB by mistake and want to restore it completely.

Note Note

Deleting the system information in the LMDB and waiting for the next automatic synchronization with the SLD does not re-create the system description consistently. It only updates the information that has changed since the last system registration, and a fragmentary system description will appear in the LMDB.

End of the note.

There are two ways of restoring system descriptions from the SLD:

Resynchronization in the technical system editor:
Does not delete or overwrite assignments and manually created information in the LMDB, for example, information about installed products that was not reported automatically by a data supplier.
Resynchronization by report:
Can overwrite all values in LMDB with SLD values, even if the corresponding fields are not filled in the SLD. So any values in the LMDB are cleared if there is no value in the SLD.

Can delete the complete technical system information in the LMDB, including assignments and manually created information.

Prerequisites

See Editing Technical System Information.

If the same system is described differently in two SLDs attached to your LMDB, remove the incorrect information from the SLD first.

Procedure

Resynchronization from SLD in Technical System Editor

You can restore the complete technical system description from the SLD in the technical system editor:

Start transaction SM_WORKCENTERand choose SAP Solution Manager Administration Landscape Technical Systems .
Select the technical system and choose System Operations Maintain System

(You can also access the LMDB directly with transaction LMDB.)
Choose Advanced Resynchronize Technical System from SLD .
If there is more than one SLD connected, select the one with the correct system description and choose OK.
Review the changes made by resynchronization.
Choose Save to persist the changes.

Only data from automatic SLD data suppliers is synchronized. Data that was created manually in the SLD is ignored. Data that was created manually in the LMDB is not deleted. All manual assignments, for example product assignments, remain in the LMDB. To delete manually created data and assignments, refer to the next section.

Resynchronization by Report

There are reports to restore SLD data completely. They delete all assignments and data that was created manually in the LMDB.

Caution Caution

Be sure that you really want to delete all manually created system information and assignments, such as product assignments. You may not be able to recover configurations that you delete, such as diagnostics-relevant indicators.

End of the caution.

Start transaction SA38 and run one of the following reports:
- RLMDB_SYNC_TECHNICAL_SYSTEM (for a selected technical system)
- RLMDB_SYNC_ALL_TECH_SYSTEMS (for all technical systems in the LMDB). For more information, see SAP Note 1949792.
Choose the info button and read the help text for the report.
Make your selection.
Run the report in simulation mode first.
When you are sure that the report will achieve the desired result, deselect the Simulate only indicator and execute the report.
The synchronization can take a few minutes, depending on the number of CIM instances.
Repeat the Managed Systems Configuration in the SAP Solution Manager: Configuration work center.
