On IBM i sometimes an obvious SQL7008 error can not be solved by a simple command which used to be a solution.
SBMJOB CMD(AS4FIXFILE DBLIB(R3<SID>DATA) CHGOWN(*YES)
ENDJRN(*YES) STRJRN(*YES)) JOB(AS4FIXFILE)
In such case, please also think about data area of QDFTJRN.

If you see this, Please delete DTAARA(R3STTDATA/QDFTJRN) then your AS4FIXFILE command
will active journal again.
