You can dynamically change the following local SNA major node operands by editing the VTAMLST and then issuing the VARY ACT,UPDATE=ALL command. You can specify the new operand value on a higher-level definition statement for sifting, if applicable.
| ASLENT |
MDLENT |
| Note: *
You can dynamically change ISTATUS only on the LU definition statement.
|
|
To dynamically change the operand, the resource to which it applies must be inactive. For instance, an operand on an LU definition statement which receives its value from a PU definition statement can be dynamically changed only when the LU is inactive; the PU can remain active.
You can dynamically change the operands associated with tables (ASLTAB, LOGTAB, MDLTAB, MODETAB, and USSTAB) at any time without deactivating resources.
See z/OS Communications Server: SNA Network Implementation Guide and z/OS Communications Server: SNA Operation for more information about the VARY ACT,UPDATE=ALL command.
