Error description

  • Tivoli Storage Manager can be executed via root login the
    following way:
    
    /opt/tivoli/tsm/server/bin/dsmserv -u instance_user  -i
    /instance_path
    or
    /opt/tivoli/tsm/server/bin/rc.dsmserv -u instance_user  -i
    /instance_path
    .
    
    Above command will start  a V6 tivoli Storage Manager Server
    under the instance_user.  However, the server will run under the
    root user's resource limit.  This may cause some  unexpected
    behavior if the root user's resource limit is much lower than
    the instance_user's resource limit, or if the root user's
    resource limit does not meet Tivoli Storage Manager V6 server's
    minimum requirement.
    
    L2/customer Diagnostics:
    
    1: A V6 Tivoli Storage Manager Server is running with the
    following configure:
    
    root user's hard and soft limit of nofiles is 1024
    ulimit -Hn 1024
    ulimit -Sn 1024
    
    tsminst1 or instance_user's nofiles hard and soft limit is 65536
    ulimit  -Hn 65536
    ulimit -Sn 65536
    
    .
    2: Starting Tivoli Storage Manager via the following command:
    
    /opt/tivoli/tsm/server/bin/dsmserv -u tsminst1  -i
    /home/tsminst1
    or
    /opt/tivoli/tsm/server/bin/rc.dsmserv -u tsminst1  -i
    /home/tsminst1
    
    3: After server starts , the following warning is logged in the
    actlog:
    
    ANR3619W The user limit for open files is below  the
    recommended minimum value of 4096.
    
     4: db2diag.log shows the DB2 is getting root id's nofile :
    
    nofiles (descriptors)  = 0x00000400
    
    Decimal value  of 400 is 1024.
