HI all,
I'm facing a problem concerning duplicate entries (SID and SID00001)i n LMDB for a system after its move from one host to another in comination with an update to SW components.
While SLD recogniced system move and updated the name of the system (SID and hostname) from the old one to the new one, a seconde entry was beeing created in LMDB. SAP recommends to delete both technical systems from LMDB, re-create the new one and re-sync system data from SLD.
Unfortunatelly this is only possible if the 'old' system isn't in use. As the system is already in use for e. g. technical monitoring, DVM, proactive monitoring, test management, mopz, EWA a.s.o, this is NO OPTION. Whne removing a system from LMDB all links to solutions are beeing deleted, which guides to data loss.
My first idea is, to
- create a dedicated product system for new technical system
- create a dedicated logical componeten for technical system and product system
- replace logcial component in all relevant solutions in solman_directory and test management
- remove old logical component, product system and technical system.
but ... will this work without data loss?
Second idea:
editing LMDB data, but I don't know internel structure of LMDB
Note 1694004 - Dealing with duplicate technical system names (SIDs) describes the issue, but last sentence says:
In rare cases, the renamed system may have received a new extended system ID in the LMDB. After a thorough check, the desired ID can be assigned to the system in the LMDB UI by renaming the property "Extended System ID".
Which checks have to be done. What will happen in LMDB and SMSY intenal, when I do so?
Has anybody of you knowledge, how to deal with this problem.
Thank you for your help
Norbert
