Hallo,
ich hatte folgendes Problem:

V5R3 has a new IFS directory attribute "Restricted rename and
unlink". If this is set to *YES QMSF can fail with TCP5104
Integrated File System file unlink failed" for /tmp/... on
QtmmSendMail users.



The default value for the new attribute is *NO on the CRTDIR
(MD) command. However, we set the attribute for *YES when we
have to create it, such as on scratch installs or some other
instance where the directory has been deleted. Slip installs
should not be affected, provided slipping the GA resave. Once
the attribute is set, it will remain set. This is compatible
with UNIX implementations and is documented in the Memo-To-Users
If the attribute is set to *YES and is causing QMSF to fail,
change it to *NO using the CHGATR command:
CHGATR OBJ('/tmp') ATR(*RSTDRNMUNL) VALUE(*NO)
