Issue/Introduction

We no longer need CPF on this system. How do I remove it without affecting other processing?

 

Environment

Release:
Component: ACF2MS

Resolution

CPF can be removed from the system without an IPL. These are the steps:

1. Issue a SHOW CPF to determine the current environment, i.e.; the names of the journal files to be deleted and the identity of other nodes whose CPF records may have to be changed.

• Set NOCPF in the GSO OPTS record for the appropriate sysid.

• Delete the CPF records.

• REFRESH the OPTS and CPF records.

• Stop CPF.

• Issue SHOW CPF to verify it is stopped. 

• Follow up with a SHOW CPF on the other nodes in the network (see #1).

• Delete the NODEDEF record defining this node from the CPF records at the other nodes.

These are the ACF2 and operator commands to accomplish these steps:

1. acf
   show cpf

• set c(gso) sysid(xxxx) for local sysid
  cha opts nocpf

• set c(cpf) sysid(xxxx)
  del options
  del like(nodedef-)

• f acf2,refresh(opts)
  f acf2,refresh(all),type(cpf)

• f acf2,cpf(stop)

• show cpf
  
  

  ****** at remote nodes ******

• show cpf

• set c(cpf) sysid(yyyy) for local sysid
  del nodedef.zzzzzzzz where zzzzzzzz is the name of the node being deleted
  f acf2,refresh(nodedef),type(cpf)

If the CPF OPTIONS record on the remote systems includes references to the deleted node, issue the following commands as appropriate:

    cha options dftcmd(zzzzzzzz)  del
    cha options dftpsw(zzzzzzzz) del
    f acf2,refresh(options),type(cpf)
