The AUTOCONNECT attribute of a CONNECTION resource
The AUTOCONNECT option specifies whether CICS® is to try to bind the LU services manager sessions at the earliest opportunity (when the z/OS® Communications Server ACB is opened).
It can have the following values:
- AUTOCONNECT(NO)
- specifies that CICS is not to try to bind the LU services manager sessions.
- AUTOCONNECT(YES)
- specifies that CICS is to try to bind the LU services manager sessions.
- AUTOCONNECT(ALL)
- the same as YES.
The LU services manager sessions cannot, of course, be bound if the remote system is not available. If for any reason they are not bound during CICS initialization, they can be bound when the connection is placed into INSERVICE ACQUIRED state. They are also bound if the remote system itself initiates communication. For a single-session APPC terminal, the AUTOCONNECT attribute has no effect. This is because a single-session connection has no LU services manager.
