Resynchronizing Technical System Information from SLD

You may have 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. For more information, see Registering Technical Systems Automatically by Data Suppliers.
Incorrect system information was migrated from transaction SMSY during the LMDB setup. For more information, see Migrating System Information from SMSY to LMDB.
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 Integration of System Landscape Management.
You deleted the system in the LMDB by mistake. For more information, see Deleting Technical System Information.

Note Note

Deleting the system information in the LMDB and waiting for the next automatic synchronization with the SLD does not recreate 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 from SLD 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 Completing Technical System Information Manually.

If data is inconsistent in the SLD, for example because 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 directly in the technical system editor:

Start SAP Solution Manager: Work Centers (transaction SM_WORKCENTER) and choose 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 LMDB is not deleted. Data that was created manually in the SLD is ignored. All manual assignments, for example product assignments, remain in the LMDB. To delete manually created data and assignments, refer to the next section.

If installed product information is updated with the resynchronization, the related product systems are automatically updated asynchronously. When you have saved, wait at least 5 minutes before you change a related product system.

Resynchronization by Report

Caution Caution

Be sure that you really want to delete all manually created system information and assignments, such as product assignments. You can delete configurations that cannot be recovered, such as diagnostics-relevant indicators.

End of the caution.

To restore SLD data completely, including the deletion of assignments and of data that was created manually in the LMDB, use the report RLMDB_SYNC_TECHNICAL_SYSTEM:

Start transaction SE38 and run the report RLMDB_SYNC_TECHNICAL_SYSTEM.
Read the help text in the report.
Make your selection. Decide whether to use the Overwrite or Delete before resync functions.

Caution
When you select Delete before resync you delete all data that you entered manually, including any assignments that you made in the LMDB, for example assignments to product systems or to a dual-stack.

End of the caution.
Run the report in simulation mode, first.
When you are sure that the report will achieve the desired result, deselect the Simulate indicator.
The synchronization can take a few minutes, depending on the number of CIM instances.
