Considerations
STYPE OSS
specifies that the type of server is an OSS NFS file server. NFS file servers store
and provide access to NFS files, which are typically in formats compatible with PCs
or workstations: that is, files compatible with DOS or UNIX.
SWAP [ file-name ]
specifies a file used to hold the server process’s virtual data. This attribute allows
you to specify a permanent file for swapping the data stack and to specify a different
volume for the swap file. See the RUN command in the TACL Reference Manual
for more information about specifying a swap file.
WRITE-THRU { TRUE | FALSE }
specifies whether data written by NFS clients to NonStop Himalaya systems is
written to cache or directly to disk. Configurations involving high-performance
applications should set this parameter to TRUE while those involving high-
reliability applications should set this parameter to false.
The default value is FALSE.
SEL [ NOT ] state
specifies the summary state select option. You can use the SEL STOPPED option to
specify that you want to alter only SERVER objects in the STOPPED summary
state.
Considerations
Consider the following points when using the ALTER SERVER command:
•
ALTER SERVER is a sensitive command requiring super-group access, or super-ID
access if NULL-ALIAS-OK and ROOT-USER-OK are TRUE.
•
When you alter a SERVER object, it must be in the STOPPED summary state.
•
To remove the existing SWAP attribute value, specify the SWAP attribute keyword
without a filename value.
•
Use the INFO SERVER command to determine the current attribute values of a
SERVER object.
•
If you specify multiple parameters in any ALTER command and an error occurs,
some of the processing might be complete even though the processing was
interrupted. Use the appropriate INFO command to determine which of the
requested changes were made before the error occurred.
•
To move a backup server process from one processor to another, two ALTER
SERVER commands are required. The current backup process must first be stopped
by issuing an ALTER SERVER command that sets the BACKUP attribute to -1.
The backup process can then be restarted in the target process by issuing an ALTER
SERVER command that sets the BACKUP attribute to the value of the target
processor.
