APAR status

  • Closed as documentation error.

Error description

  • The system requirements documentation does not specify that
    ulimits be set to unlimited, if possible. TSM also attempts to
    set the ulimits to unlimited during installation, although this
    is not documented in the readme.
    .
    Customer/L2 Diagnostics (if applicable)
    None
    .
    *NOTE*
    Searching the 6.1 documentaion  there is a note under "Tivoli
    Storage Manager concepts"
    .
    Following the documentation path:
    http://publib.boulder.ibm.com/infocenter/tsminfo/v6/index.jsp?to
    pic=/com.ibm.itsm.nav.doc/r_map_ic.html

    .
    Note: When you start the Tivoli Storage Manager server, the
    server attempts to change the ulimit values to unlimited. In
    general, this helps to ensure optimal performance and to assist
    in debugging. If you are a non-root user when you start the
    server, attempts to change the ulimits might fail. To ensure
    proper server operation if you are running as a non-root user,
    make sure that you set the ulimits as high as possible,
    preferably to unlimited, before starting the server.
    .
    This includes setting DB2ᄅ user limits as high as possible. DB2
    relies on private data memory for sort memory allocations during
    SQL processing. Insufficient shared heap memory can lead to
    Tivoli Storage Manager server failures when interacting with
    DB2. For more information on setting the appropriate platform
    values, see the following Technote:
    http://www.ibm.com/support/docview.wss?uid=swg21212174

Local fix

  • Set ulimits for DB2 user and TSM user to unlimited or as high as
    possible.
