http 500 error, but at least the TLS handshake got completed apparently.
Thought when trying to open a session with NIM using https://aaw10.sysplex.prod.com.au:8888/ca-nim-sm/ui/configurations.jsp
receive the 500 error. Cannot find full TLS session from SMF 119 subtype 11 and 12 records after that.
Release : 1.1
Issue was due to the TAMz STC Logonid including the character $ which in USS was seen as variable.
Had to put the user SSD$TAM into quotes in both the line corresponding to the keyring name (TAMENV and TAMJVM) and the WEBINF_PATH export in TAMENV.
Fixing only the kerying line was fixing the TLS issue but blocked with HTTP 500 error.
