Solution (sort of) to "Load Indicator not supported by OS" problem

During database creation, even if you choose "Dedicated Server Mode" instead of "Shared Server Mode" (for MTS), you will actually be using dedicated server processes for Net8 BUT you will still use MTS for IIOP connections. That's why you have those MTS_ entries in your INIT.ORA file.
The reason is IIOP connections to 8i can only be done with MTS.
So, if you are not interested or will not use 8i to handle IIOP connections (in that case, maybe stick with 8.0.5 or use OAS ), comment out all MTS entries in your INIT.ORA file, restart the instance / database.
You will then notice that the alert log has no more "Load Indicator not supported by OS" entries, while the pmon trace file will have only one entry for that message, just after startup, but never again.
If you are interested on IIOP connections ( e.g.: the reason you chose 8i instead of 8.0.5 and OAS ), then I think Oracle is the only one who can answer this problem. Or maybe somebody with a support contract with Oracle can ask Oracle about this.
So what does the error message mean? From what I have read, an 8i listener registered with multiple 8i dispatchers chooses the dispatcher that has the least load.
However, even if I specify in my INIT.ORA that there is only one dispatcher (therefore assuming that it won't have to check the load of the dispatcher since there is only one to choose from), it still generates the error message.

If anyone knows any better about what I wrote, please let me and everyone else in this forum know.

    Yes, them are here. Not in init'instance'.ora, but in

  • Alert log message : Load Indicator not supported by OS

    Try turning of the Multi-threaded server option (i.e. comment out "mts" references in the init[SID].ora file). This appears to be an MTS-related bug.

    Unfortunately, the RAM shortage on my PC mandates the use of MTS. I've modified the
    startup procedures to clean up the trace & log files, so my filesystem doesn't get filled up to the brim. I can live with the few messages in my trace & log files.

  • 8i: Load Indicator not supported by OS!

    I get a message in my PMON background dump file that
    reports 'Load Indicator not supported by OS!'. I am not sure
    what this is referring to, what the impact is on the stability
    of the instance, or what to do about it.
    I am running Oracle8i 8.1.5.0.1 (yes, the new patch) on RedHat
    6.0. I got the same message prior to installing the patch. I
    even built a new database to see if it was related to 8.1.5.0.0,
    but I still get the same thing. The problem occurs even with no
    one connected to the instance (there is only one instance on
    this machine). The error message keeps repeating and the dump
    file keeps growing.
    Is anyone else seeing this? Is there something I need to
    configure into my kernel? I am running kernel version 2.2.10
    configured for SMP on a dual processor Pentium III system.

    According to my information, which was obtained in a private
    conversation, the new Oracle8i feature that is supposed to
    help with load balancing, namely the resource allocation plans,
    uses a facility that doesn't exist on Linux. As those resource
    plans are checked frequently by PMON, the message is being
    constantly reiterated. You can limit the size of a trace file
    to 10k and the message will stop. It would be nice to have a
    parameter to disable this feature.

  • Any word on 'Load Indicator Not Supported' error?

    Has anyone figured this one out yet? According to the Admin
    Guide, the MAX_DUMP_FILE_SIZE will only control the trace files,
    not the alert file. It CAN be safely deleted, even with the
    instance up.
    What a pain :(
    null

    I also have this problem and it is sort of solved by disabling the Multi Threaded Server option.

    Disable MTS by removing the parameter MTS_SERVERS from the init.ora file and any other MTS parameters
    Note: You will still get the Load indicator error by it will not repeat in your alert log file. and it appears only at startup for the database
    Solution #2
    If you absolutely need MTS then set the init.ora parameter MAX_DUMP_FILE_SIZE very large so that your server will not crash by populating your alert.log file with the load indiator error and periodically clean the log out.
