Spectrum VNMSH hanging on "show parents" request

Some interfaces are presenting  "<unknown>" values in the 0x12adb attribute:
Whenever I try to use "show parents" to get the Model Handle of this GC, the command and vnmsh in general hangs and I have to restart it.


Release : 10.4.1

Component : Spectrum Core / SpectroSERVER


The customer SSdb file got corrupted due to which vnmSh was hanging. Also the "" string is added to CollectionsModelNameString(0x12adb) attribute if SS fails to read the model_name attribute on the corrupted models. I tried all the ways to delete the corrupted models with SSdebug and CLI tools but no luck. The only option to remove those corrupted models is that run the MGW command.  Due to the corruption, all the models needs to be re-created and re-evaluated to address this problem. To do so, run the Modelling GateWay to overcome this issue on the latest SSdb file.

1. Run the MGW export command using spectrum installed owner from /SS folder
../SS-Tools/modelinggateway -vnm -e .xml

2. Once XML successfully generated then stop SS and tomcat servers.

3. Initialize to legacy SSdb using below command,
../SS-Tools/SSdbload -il legacy.SSdb

4. Now, Start SS and tomcat servers

5. Import the XML file using below command with spectrum installed owner
../SS-Tools/modelinggateway -vnm -i < exported XML file name>.xml

6. Once XML file is imported then start oneClick/webApp clients and check the behavior.
