FACT(s) (Environment):
UNIX
FIX:
The UNIX mount_nfs utility attaches a named resource to the filesystem hierarchy at the pathname location mount_point, which must already exist.
The following are Progress recommended mount_nfs utility options to optimize database performance:
- no_atime used to avoid updating an inode's last access time attribute each time the file is read. However, it is important to note it's effective benefits vary for each individual operating system.
- noac is used to suppress data and attribute caching. It should be used so that data written by the database is written immediately.
- hard will continue to retry requests until the server responds.
-nointr will not allow keyboard interrupts to kill a process that is hung while waiting for a response on a hard-mounted file system. The default is intr, which makes it possible for
clients to interrupt applications that may be waiting for a remote mount.
