Make MODDVIPA available via a console command

It was recommended recently that we use MODDVIPA to ensure that an IP address remains with the stack.

//CDVIPA EXEC PGM=MODDVIPA,PARM='-c XXX.XX.XXX.XXX'

//SYSOUT DD SYSOUT=*

- At the end of the proc, add:

//DDVIPA EXEC PGM=MODDVIPA,PARM='-d XXX.XX.XXX.XXX',COND=EVEN

//SYSOUT DD SYSOUT=*


It's been some years since we experimented with it and at the time it was available only in batch. There were also issues deleting the DVIPA at the end of the job/proc so we were not able to implement it.


Since we now use automation to start and stop tasks via zOS console commands it would be nice and also consistent if there were a TCPIP console command to create and delete a DVIPA.

    After reviewing your request, it is being rejected because we have determined that this is not something likely to be implemented. For what you want to do (automation to create/delete dynamic VIPAs via the z/OS console), it can be accomplished today using existing functions. To do this, you would create two new procedures, one to create the dynamic VIPA via the MODDVIPA utility:
    //TCPDVC EXEC PGM=MODDVIPA,REGION=0K,TIME=1440,PARM='POSIX(ON) ALL31(ON) -c dynamic-vipa-address'
    and one to delete the dynamic VIPA via the MODDVIPA utility:
    //TCPDVD EXEC PGM=MODDVIPA,REGION=0K,TIME=1440,PARM='POSIX(ON) ALL31(ON) -d dynamic-vipa-address'
    Your automation would then start the TCPDVC procedure to create the dynamic VIPA and then start your job that needs to use that dynamic VIPA. When stopping the job, your automation would first stop the job and then start the TCPDVD procedure to delete the dynamic VIPA.
