ALTER SC
Considerations
•
For ALTER commands, the values for tokens and fields omitted from the command
buffer remain unchanged.
Reset values for each field are predefined. These values are described in
Section 3, SPI Programming Considerations.
To reset ZDEFAULTVOLUME, ZGUARDIANLIB, ZHOMETERM, ZIN, ZOUT, or
ZPROGRAM with the TACL program, you must use the #SETBYTES built-in
function. For more information, see the SPI Programming Manual.
•
The tokens and fields included in the command buffer must be valid for the
process type defined for the server class.
•
To specify node independence for server class attributes, specify \* for node
names or omit node names and set ZNODEINDEPENDENT to ON in the START
PATHWAY command.
•
If you have added the maximum number of server class entries supported by the
PATHMON process (that is, 4095) and issue an ALTER SC command, the
command fails with the error:
*1102* TOO MANY SERVER ENTRIES
The command fails because the PATHMON process executes the ALTER SC
command by creating a new server class entry with the altered values before
deleting the existing server class entry. When the maximum number of server
class entries already exists, the PATHMON process does not have the space to
create a new server class. To avoid generating the preceding error, define and add
the maximum number of server class entries allowed minus one (that is, 4094
server classes).
•
When changing the definition of an associative server, make sure you make the
changes everywhere the associative server is defined. Otherwise, you cannot be
sure that the new definition will be implemented or permanent.
