Configuring Advanced Server for UNIX Guidelines for NFS file systems

5.2 Guidelines for NFS file systems

If the UseUnixLocks=1 entry has been set in the Registry, Advanced Server for UNIX executes record locks in all file systems, including the NFS file system. The default is UseUnixLocks=0, UseNfsLocks=0, NfsCheck=0.

Overview:

Parameter	Parameter	Comments
UseNfsLocks=1		The lock or unlock command is always executed,
		an error message may be passed on to the appli-
		cation. The NfsCheck= parameter is ignored.
UseNfsLocks=0	NfsCheck=0	The lock or unlock command is always executed,
		if an error message appears, it is acknowledged
		positively.
UseNfsLocks=0	NfsCheck=1	The lock or unlock command is only executed if the
		file is not contained in the NFS file system. If the
		file is contained in the NFS file system, the
		command is not executed, but is acknowledged
		positively.

●The incorrect locks can cause processes to hang in systems that have not

!configured a lock manager. These processes cannot be terminated with kill -9; in this case the system must be restarted.

●In this case, set the entries NfsCheck=1 and UseNfsLocks=0.

5.3Connecting Advanced Server for UNIX to Logging

Advanced Server for UNIX has an interface to Logging. If users wish to use Logging it must be installed and started on the server system.

ÊCheck whether the log files log3admin and log3struct (for Logging V3.0) contain entries for Advanced Server for UNIX. If necessary, incorporate them using an editor.

ÊAfter you have entered it using the editor, invoke the log3/bin/log3adm and log3/log3new commands. In this way, the entries are incorporated from log3admin to log3admin.obj.
