This topic describe the steps for modifying the LINK statement.
Procedure
Perform the following steps to modify all other parameters
on a LINK statement or to modify any DEVICE statement parameters:
- Stop the device.
______________________________________________________________________
- Use a VARY TCPIP,,OBEYFILE command with a data set that
contains:
- A new HOME statement that does not contain the home IP address
or addresses of the LINK or LINKs involved in the DELETE
- DELETE linkname and DELETE devicename statements
______________________________________________________________________
- Use a VARY TCPIP,,OBEYFILE command with a data set that
contains:
- The changed DEVICE and LINK statements
- A new HOME statement that includes the home IP address or addresses
of the LINK or LINKs being added
The data set used on the VARY TCPIP,,OBEYFILE command in
this step should be different from the data set used in step . Do not put the DELETE and redefinition of
an interface in the same OBEYFILE data set.
______________________________________________________________________
- Start the device.
______________________________________________________________________
Results
Guideline: To change parameters
on a LINK statement only, you do not need to delete the DEVICE name
statement and later redefine the DEVICE name statement.
To
dynamically change a value on a LINK statement only, do not perform
the DELETE devicename and redefine DEVICE steps in Steps for modifying LINK statements.
For
more information about the VARY TCPIP commands,
see z/OS Communications Server: IP System Administrator's
Commands.
You can add new DEVICE and LINK statements
using the VARY TCPIP command. You can also delete and redefine existing
statements.
When you add new LINK statements, any corresponding
BEGINROUTES, GATEWAY, HOME, and TRANSLATE statements coded to include
the new links are treated as replacements for active statements. Therefore,
when you code the BEGINROUTES, GATEWAY, HOME, or TRANSLATE statements
of the data set specified on a VARY TCPIP,,OBEYFILE command, be sure
to include new and existing links that you want to have active in
your configuration.
