  • 1.  archecker error with PSM

    Posted 29 days ago
    Hi,
    Level 0 and log backups are being made using psm on an AIX system for testing.
    I tried to recover the table with archecker using psm's backup, but I get an error as below.

    command)
    archecker -bdvs -f schemafile

    onbar backups or restores are performing fine.
    I also tried slibclean , but it's the same. Any other solutions?

    Is archecker being tried on same system where also the backup had been created?  In which case I'd wonder how libbsapsm.so can be good enough for the backup, yet not for archecker - maybe an environment problem?

    If on different system, then that seems to be missing some library.

    What's  ldd's perspective on this?

    Here it would show:
    $ ldd libbsapsm.so
    libbsapsm.so needs:
    /usr/lib/libc.a(shr_64.o)
    /usr/lib/libpthreads.a(shr_xpg5_64.o) <<< this is the relevant one and had been found on my system
    /unix
    /usr/lib/libcrypt.a(shr_64.o)

    BR,
     Andreas

    Hi Andrea, Thanks for your reply.

    Backup and restore were performed on the same instance on the same server.

    The ldd output for the libbsapsm.so file is shown below.
    Informix version is 12.10.FC12WE, OS is AIX 6.1.


    $ ldd libbsapsm.so
    libbsapsm.so needs:
    /usr/lib/libdl.a(shr_64.o)
    /usr/lib/libc.a(shr_64.o)
    /unix
    /usr/lib/libcrypt.a(shr_64.o)


    Thanks,
    SangGyu Jeong
