Using ENF event code 80 to listen for rpcbind events z/OS Communications Server: IP Programmer's Guide and Reference SC27-3659-02 |
|
The rpcbind server uses ENF event code 80 to send signals when rpcbind completes initialization or when rpcbind is stopping. Authorized RPC applications can use the ENFREQ LISTEN service to detect rpcbind server events. On the ENFREQ service, specify the X'80000000' event qualifier and the listener user exit routine that is to receive control after the specified event occurs. The specified listener user exit receives control when the rpcbind server completes initialization or when the rpcbind server is stopping. Requirement: The RPC application must be authorized. The listener
user exit must run as an SRB.
To listen for ENF event code
80, specify the qualifying events on the BITQUAL parameter, which
specifies one of the following qualifiers:
When the listener user exit is driven, the ENF80 and ENF80_RPC
control blocks are provided. The exit can use ENF80_RPC_FLAGS to determine
whether the rpcbind server is initializing or stopping. The job name
of the rpcbind server is also provided.
If the RPC application does not need to know whether the rpcbbind server is running, issue the ENFREQ REQUEST=DELETE request to delete the listen request. For information about ENFREQ and
listener exits, see:
