MOUNT
/BACKGROUND [= {DELAY:OpenVMS_delta_time | RETRY:n}]
Optional. Defaults:
• If you omit this qualifier, background mode mounting is not attempted.
• If you omit the DELAY keyword, background mode mounting is set up with
/BACKGROUND=(DELAY:00:00:30,RETRY:10).
This qualifier enables background mode for mounting the file system.
The optional DELAY time specifies amount of time to wait if the mount attempt
fails before trying again. Specify the time as hh:mm:ss. The maximum delay
period you can specify is approximately 49 days. The default delay time is 30
seconds.
The optional RETRY keyword specifies the number of times to repeat the attempt
to mount the file system. RETRY:0 means that the client uses the first try only.
The default number of times to retry is 10.
If you use the /BACKGROUND qualifier, you must also use the /RETRIES
qualifier and specify a nonzero value. For example:
$ TCPIP MOUNT DNFS0: /BACKGROUND=RETRY:9 /RETRIES=4 /HOST="robin" -
_$ /PATH="/USR/USERS/GEORGE"
In this example, you are asking for four data retries on each mount attempt
and nine mount attempts, for a total of 36 tries. If you use the default value for
/RETRIES, the first mount attempt can never complete except by succeeding, and
the process doing the mount will hang until the server becomes available.
/CACHE_TIMEOUT=
[ DIRECTORY:OpenVMS_delta_time ]
[ ATTRIBUTE:OpenVMS_delta_time ]
[ READ_DIRECTORY ]
Optional. Defaults:
If you omit this qualifiier, the file system is set up with caching timeouts as
follows:
/CACHE_TIMEOUT=(DIRECTORY:00:00:30,ATTRIBUTE:00:00:15)
Specifies the following caching timeout information for the mount point:
• DIRECTORY:OpenVMS_delta_time
Amount of time that the client waits between rereading a directory’s
status or contents.
Specify OpenVMS_delta_time as hh:mm:ss.
• ATTRIBUTE:OpenVMS_delta_time
Amount of time that the client waits between rereading a file’s attributes
from the NFS server.
Specify OpenVMS_delta_time as hh:mm:ss.
• READ_DIRECTORY
Forces the client to read the contents of the directory requested when the
cache timeout occurs rather than rely on the directory’s modified time.
