    Hello,

    can a system wpar or application wpar be provisioned with fixed cpu and memory?
    if i want to provision a system with aix and db2 from a LPAR which has already aix and db2 installed, can i use system wpar or application wpar technology to provision system with dedicated cpu and memory resources ?
    regards,

    WPARs of either type can be setup with resource controls - for specific CPU numbers you best use Resource sets (RSET). And you can determine the memory.

    Do be careful because its easier to damage performance this way.
    Like a WPAR paging badly when the Global AIX has spare RAM - which seems pointless.

    Your term "provision" is ambiguous.

    You can create a "master" WPAR configured with DB2 installed.
    Then back this up and use it you create many more but WPAR cloning - this is really a WPAR restore but also reconfigure network, hostname, disks as part of the restore.

    See WPAR movies for examples at http://www.ibm.com/developerworks/wikis/display/WikiPtype/Movies

    There is currently no mechanism to convert a currently running LPAR in to a WPAR.
    You need to rebuild it and move the data - I presume you have a LPAR build procedure to create NIM mksysb resource so you can use the same procedure/script/tools.

    I hope this helps, thanks Nigel Griffiths
