Error description

  • When performing "audit library" for a library of libtype
    'shared', and there is
    no database backup volume for the server issuing the command, in
    this library, the server may crash.
    
    On Linux platform, the stack in getcoreinfo.txt will look like:
    
    #0  0x0000000000a660af in icGetDBBackupVolList (isFile=False,
    dbBackupVolListP=0x7fffc1659db8) at icutil.c:2254
    #1  0x0000000000a3ea99 in ShareAudit (auditP=0x7fffa00275ce) at
    mmsshr.c:1930
    #2  0x00000000009d245a in AuditThread (argP=<value optimized
    out>) at
    mmslib.c:15857
    #3  0x0000000000dfc3e6 in StartThread
    (startInfoP=0x7fff7c061008) at
    pkthread.c:3369
    #4  0x000000392a0079d1 in start_thread () from
    /lib64/libpthread.so.0
    #5  0x00000039298e88fd in clone () from /lib64/libc.so.6
    
    The audit library command will check the previous DB backup
    volumes list
    when the library is defined as a shared library. If the server
    is unable to find one,
    the server crashes. This issue is only applicable to shared
    libraries, containing
    no database backup volumes from the server issuing audit library
    command.
    
    
    Tivoli Storage Manager Server Versions Affected:  6.3.3.000 and
    higher, and 7.1.x on all supported platforms
    
    Initial Impact: Medium

Local fix

  • Perform "backup db" first using a device class associated with
    the
    shared library, then run "audit library" command, if using
    libtype=shared.
