How do I resolve a z/OS Enterprise Extender connection failure with reason code 00000010 ?

The reason code 00000010 indicates that the port number requested by the caller cannot be reserved.

For Enterprise Extender connections, the job name on the PORT statements in the TCPIP.PROFILE for ports 12000 - 12004 must be the same as the name that VTAM is started with. Message EZD0802I indicates that the stack has reserved the ports for a different name than VTAM's.

Ports 12000 - 12004 should be reserved for VTAM. This prevents any other applications from using these ports.

You can use either a single PORTRANGE statement or a single PORT statement specifying all reserved port numbers to reserve ports 12000 -12004 for VTAM.

Use of PORTRANGE: PORTRANGE 12000 5 UDP NET ; RESERVE UDP PORTS 12000-12004 FOR EE

Use of PORT:

 PORT 12000 UDP NET ; RESERVE UDP PORTS 12000-12004 FOR EE 
      12001 UDP NET
      12002 UDP NET
      12003 UDP NET
      12004 UDP NET

Use the MVS job name associated with the VTAM started task to reserve UDP ports that are to be used for EE connections. The MVS job name for the VTAM started task can be determined in the following order:

1. The job name specified in the JOBNAME= parameter or the identifier specified on the MVS START command. In the PORTRANGE example, VTAM was started with an identifier of NET and therefore the job name specified was NET.

2. The job name specified on the JOB JCL statement within VTAM’s JCL

3. The proclib member name
