After upgrade production DB from 8.3 to 10.1.5 we have problem to connect to one of two upgraded tc databases.
Command line login fail! Error code = 70101 (POM_no_class_of_this_name)
POM_class_id_of_class failed with code "POM_no_class_of_this_name"

FSC service is working Ok. What can be corrupt? May be in tc_data?
Also, we moved upgraded to tc10 tc_database to another server.
Solved! Go to Solution.
The DB flavor, Oracle or MSSQL, determines which files need to be modified in TC_DATA when moving the DB instance to a different server. MSSQL is simple and you only need to modify tc_profilevars.bat. Oracle also requires modifying tnsnames.ora.
Validate that your connection to the database is good by running:
Don't forget to:
NX 11.0.1.mp01 | SW 2016 | TcUA 11.2.3
Problem was in corrupt TC_ROOT. We replaced corrupt TC_ROOT with correct TC_ROOT from backup and this error went away
