  • 1.  Upgrade from IDS 15.0.0.2 to 15.0.1.0 errors for IPA's

    Posted Thu February 05, 2026 02:54 PM

    Hi everyone,

    When I try to upgrade from 15.0.0.2 to 15.0.1.0 I have errors about IPA's.


    On 15.0.0.2 I run for each database:

    select sysadmin:task("table update_ipa",tabname)
    from systables
    where tabid >= 100
    and tabtype = "T"
    ;

    When I start 15.0.1.0 I have the following messages:

    14:11:57 Insufficient free huge pages in /proc/meminfo for shared memory segment.
    Requested: 228978688 bytes. Available: 0 bytes.
    The default memory page size will be used.

    I run oncheck -pT for each database and there is no IPA.

    OS: OpenSuse 15.5 on VMware
    Linux compt-flexio-dev 5.14.21-150500.55.39-default #1 SMP PREEMPT_DYNAMIC Tue Dec 5 10:06:35 UTC 2023 (2e4092e) x86_64 x86_64 x86_64 GNU/Linux

    I try fix_ipa from Art Kagel but it did't find any IPA.

    What's next ?

    Thanks

    Just curious:  would omitting the "tabid >= 100" filter in your update_ipa query avoid this problem?
