After the TXK patch, both paths should be EBS_domain instead of EBS_domain_SIVACC.
Maybe the run fs didn't get the right context file sync. Did it create a new context file on run? what is in the context_file?
Please check below document
Oracle E-Business Suite Applications DBA and Technology Stack Release Notes for R12.AD.C.Delta.11 and R12.TXK.C.Delta.11 (Doc ID 2527995.1)
To improve cloning efficiency, the Oracle E-Business Suite WebLogic Server domain name no longer includes any instance-specific information. The domain name for all Oracle E-Business Suite instances is now simply 'EBS_domain'.
