  • 1.  AIX Page Spaces + WebSphere

    I am fairly new to the AIX 5.3 O/S and I had some question about paging spacing (auto option in particular).

    I looked at the man-page for lsps and also tried searching google and this forum, but could not figure out what the "auto" column means in the output of "lsps -a".

    Also, what are the consequences to any processes, in my case WebSphere Application Server instances, that need to use page space if all the page spaces are set to auto=off and the owner of the WAS instances in question cannot read /etc/swapspace (i.e., root owned -rw-r-----)? From what I understand that is the file that contains the page space device locations.

    Update:
    Ok, so I sort-of found the meaning for auto under the man page for mkps, but what happens if page space is not "configured at subsequent restarts". I am looking at all this because of some strange out of native memory exceptions we are getting from WAS after a reboot...

    The permissions on /etc/swapspaces will not cause applications a problem. This file is read by the OS, not the applications.
