John,

TeraSAM & VCP both use JCL to update the CPU code. So for VCP, you can either overlay the cpu code in the JCL, or, add another cpu code. You can enable VCP without disabling.

For PSP, you will need to update the cpu code (assemble), REFRESH LLA, stop the subsystem, then start the subsystem.

For all the router products, the cpu code (license) is checked at the time of enable, it's just that PSP uses a subsystem running as a started task, so that adds a layer of complexity...

Let me knof if you have further questions...

Dave,
I now understand that I must recycle SWSCTL21 for PSP to obtain new cpu code but we run VCP as a proc (started task):
//VCP PROC
//*
//VCP141 EXEC PGM=VCPINIT,
// PARM=('ENABLE,PROD14,NOSTATS,NORLSE,NOESDS',
// '548750446256') 2096-Q04 EXP 09/30/2009
//*
//SOFTLIB DD DISP=SHR,DSN=PSI.VCP.LINKLIB
//CONREP DD DISP=SHR,DSN=PSISP.VCP.REL141.CTLREP.PSI1
//SYSPRINT DD SYSOUT=*
//CCTLIB1 DD DUMMY
//CCTLIB2 DD DUMMY
=====================================================
If I just start it again with the newer prod-code will it work correctly ??

Yes, that's correct. Basically a "zero down time", re-enabling of VCP.

Dave,

That seemed to work fine. I was just a little leery about any update to VCP on the fly.

Thanks for your help,
