ALTER PROCESS and SUBPROCESS Commands
WHERE WARNING-MODE
specifies that only processes or subprocesses in filename-list that have
WARNING-MODE set are to be altered.
WARNING-MODE { ON | OFF }
defines whether warning mode is enabled for the specified process or
subprocess. The value is required. For more information on warning mode, see
the Safeguard Administrator's Manual.
ON enables warning mode for the specified process or subprocess. The initial
value is OFF, which disables warning mode for the specified process or
subprocess.
Consideration
Using ALTER PROCESS or SUBPROCESS to change one or more attributes for a
process or subprocess that is currently running has no effect on any process currently
accessing the process or subprocess.
For example, if you change the ACL for a process to deny both READ and WRITE
authority to a user who has a process that is currently accessing the process, the
user’s process can continue accessing the process until it closes the process.
However, any attempt to reopen the process by that user results in a security violation
error (file error 48).
Example
In this example, the owner of the authorization record for the process name $JAM adds
an ACL entry to the record.
To display a report for $JAM:
=INFO PROCESS $jam
The report shows:
To alter the ACL for $JAM:
=ALTER PROCESS $jam, ACCESS \*.prs.manager (r,w,c)
To display the altered report:
=INFO PROCESS $jam
