How to trace the Logical Name Information update

[JTWang]

One logical name in my application system was modified to the shutdown value. And I don't know how can I trace the value update history record.

Please help me to trace the problem, and the method to trace the history information.

Thank you!

You could put an acl on the logical name table in which the logical exists.
And check audit afterwards.

There is not a record of who altered a logical name unless you have defined an ACL on the logical name table to generate an audit record and/or audit alarm when the logical name table is altered. See help for the SET SECURITY command for defining a ACL containing a security ACE.

[Wim Van den Wyngaert]

Commands :
set sec toto$tab/class=logical_name_table/acl=(alarm=security,access=(write+success)
set audit/aud/enable=acl
anal/aud/fu/noint
but wait some minutes because the file is written defered.

Make that audit= instead of alarm= or the alarm will only be shown in operator log.

..
and do some thinking ahead of WHICH logicals you want to monitor!

If you want MOST or ALL, then not really an issue, but be aware you might get A LOT of messages.
Otherwise, create a dedicated LNM_table for monitored logicals, and add that table to the search list of logical name tables at the desired table.
