Platform Versioning

We just installed a Platform in the System Aproval Test Environment. Afterwards we tried to make some changes and this was not really funny.

First we had to disable all Applicaiton, then we had to disable the platform and other not really nice things.

We realised, that at the moment it is not possible to do changes on the running system withou a downtime window, what is realy not nice.

The second big problem for is that we have to define the platform withou running cics regions at at beginng. After a snapshot of the Production LPAR we add Regions to this platform. Unfortunately you have at least one time to run a platform with regions otherwise the platform is not detecting the regions after adding them to the platform.

After some thinking a landed at the same point I had some months ago.

We need a platform versioning and the possibility that applications running on a platform with the same name are automaticly defined on the new version of this platform.

This would allow the system programmer to change the definition enable the new platform. At the same time the old platform is not longer active and every is running different.

The same thing you implemented for applications.

The second thing is that we need the possibility for a platform to make a refresh or lets say that the platform automaticly realises a change of regions below it. We want that an adding and removing of regions is possible in the running system.

We also would need the possibility to define the minimum cics level on a platform. This would give an interesting oportunity for the cics upgrade. You are running under 5.2 with a 5.3 CPSM. You are adding 5.3 regions to the platform definition. As you activate the new platform with cics minimum level 5.3 all applications will run on this regions. Now you can remove the 5.2 regions safely or if you need to fall back just disable the platform and everything runs on 5.2 again.

    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.

    Due to processing by IBM, this request was reassigned to have the following updated attributes:
    Brand - Servers and Systems Software
    Product family - Transaction Processing
    Product - CICS Transaction Server

    For recording keeping, the previous attributes were:
    Brand - WebSphere
    Product family - Transaction Processing
    Product - CICS Transaction Server

    I think there are 3-4 separate requirements here:
    1. We are certainly considering separating the lifecycle of a platform from the underlying CICS regions; the current restriction is not a deliberate architecture constraint but a question of priorities.
    2. We are investigating how to better support upgrades and also for a platform to declare a minimum CICS level
    3. Allowing multiple platforms to be installed into the same regions
    4. However, moving an application from one platform to another is more problematic

    A better approach to 4 might be to treat each CICS region as a sort of VM. Install platform P version 1.0.0 and add the applications. Then install P version 1.1.0 and again add applications one at a time to ensure everything is OK before making the applications on P version 1.0.0 UNAVAILABLE and removing the platform itself. Switching all the applications together could be problematic.
