We installed TNCM 6.3 GA and ITNM 3.9 GA.
When we tried to import device list from ITNM, it fails.
Support instructed us that it’s due to a known issue when ITNM using Informix as NCIM database. We followed the tech note of https://www-304.ibm.com/support/entdocview.wss?uid=swg21579433 and fixed the issue. To confirm the device list has been imported from ITNM to TNCM properly, we checked the following tables.
INFORMIX NCIM of ITNM
select * from networkconfigmgr;
DB2 ITNCM of TNCM
select * from NMENTITYMAPPING;
