(MIM) ACTIVATE Command-Activate New Features

The ACTIVATE command initiates the activation of new release features in the CA MIM complex. If all defined members of the CA MIM complex (MIMplex) agree that they are willing to support the selected compatibility level, then the system on which the command was issued coordinates the activation of the named compatibility level and all MIMplex members begin operating at the requested compatibility level.

Scope: Global

This command has the following format:

ACTIVATE COMPATLEVEL=(level,[FORCE])

COMPATLEVEL

Indicates the format of the CA MIM control file and the associated functionality that is to be activated.

level

Specifies the compatlevel based on the product release. Acceptable values for this operand are 11.6, 11.7 or 11.8.

Note: 11.6 support is only provided for users upgrading from 11.6 to 11.8.

FORCE

(Optional) Tells CA MIM to ignore the lack of responses from any inactive or non-existent systems when processing a compatibility level activation request.

Usage Notes: ACTIVATE Command

• If any active MIMplex members reject the activation of the named compatibility level, or if any defined system fails to respond (because it is inactive, or does not exist), then the ACTIVATE command is rejected. If ACTIVATE is being rejected due to the lack of a response from inactive, or non-existent systems, then the activation of the specified compatibility level can be made by including the FORCE operand on the COMPATLEVEL keyword.
• The FORCE keyword is not honored if an active system fails to respond, or if an active system specifically rejects the activation of the specified compatibility level.
• Once the requested compatibility level has been activated in the MIMplex, the installation must ensure that the corresponding change is accurately reflected on the MIMINIT COMPATLEVEL operand specification in the MIMINIT member of the MIMPARMS data set.

  Important! Failure to do this prevents CA MIM from joining the MIMplex on any subsequent restart of the CA MIM address space until the MIMINIT COMPATLEVEL parameter change is made.

Examples: ACTIVATE Command

Suppose you are running CA MIM 11.7 with COMPATLEVEL=11.7 on three systems and want to upgrade to CA MIM 11.8. You are unable to upgrade all systems at once, so you shutdown CA MIM 11.7 on one system at a time and start CA MIM 11.8 with COMPATLEVEL=11.7.

When all systems are at Release 11.8, you can issue the following command. The FORCE keyword tells CA MIM to ignore the lack of responses from any inactive or non-existent systems.

ACTIVATE COMPATLEVEL=(11.8,FORCE)
