We are unable run the stored procedure. While we connect it from DB2CONNECT we get the below error :
"DSNU003I DSNUTILS - NOT INVOKED APF AUTHORIZED". We have Added all the Joblib, steplib to the APF library and refereshed it.Even the DSNUTILS entry is very much available in SYSIBM.SYSROUTINES. but still we get this error.

Mainframe side version details :
DB2 : 8.1
Z/OS : 1.6

Please provide me a hint to trouble shoot this error.
