  • 1.  Could I force drop the database?

    Posted Wed April 28, 2021 05:18 AM
    Hello All,
    I would like to ask for advice on Informix error message.
    A specific database of the instance has fallen into an inaccessible state.

    Below is the result of running the oncheck -cc command and dbaccess.
    Fortunately, it is an unused DB, so I want to know if it is possible to force drop.

    I googled the article about the FORCE_DB_DROP environment variable, but it does not seem to apply to the 11.70 version currently in use.
    How do I delete that database?

    Thanks,


    $ oncheck -cc tsdb

    Validating database tsdb
    ISAM error: illegal argument to ISAM function.

    $ dbaccess tsdb -

    211: Cannot read system catalog (systables).

    103: ISAM error: illegal key descriptor (too many parts or too long).

    SangGyu:

    Open an IBM support case and give the support engineer access to the system one way or another and they can patch the storage to make it go away. 

    Alternative:
    Unload all of the other databases, reinitialize the instance, rebuild it, reload the databases that you can salvage.

    If it were my system, I would do the latter whether support was able to make the offending database "go away" or not as the instance seems to be unstable.

    Thanks for your reply.
    Since the system uses a closed network, it will be difficult to obtain remote support from IBM.
    This is an obsolete database and not an urgent issue, so I think it will need to be migrated to a new instance later.

    Hi SangGyu,

    any chance this is a UTF8 database and it either has been created with GL_USEGLU set and server now is running without or the other way round?

    @Andreas
    Thank you for your interest.
    The database is created in the ko_kr.ksc locale.
    Therefore, it does not seem to be related to whether or not the GL_USEGLU environment variable is set.​​​
