    7. How to Set a Workstation Alert for ConnectionStatus

    http://support.ca.com/irj/portal/kbtech?docid=593253

    Description:
    There are 4 possible Connection States:

    3 = disconnected

    2 = connected, slowly or no data

    1 = connected

    0 = unmounted

    Q. How can I build a threshold alert on a value of 0, unmounted?

    When a JVM is restarted, it jumps to 3. Then it returns to 1 when connected.

    When a JVM has been down for 30 minutes, it becomes "unmounted".

    11. TIM installation breaks the working TCP Wrapper access control for specific hosts when using SSH and /etc/hosts.allowy

    http://support.ca.com/irj/portal/kbtech?docid=572689

    Description:

    This article discusses a scenario where the TCP Wrapper access control no longer works as configured. This happens usually these after two installation steps:

    The third-party and tim-complete images are installed. Afterwards, TCP Wrapper access is open to all hosts. This is because the openSSH version of sshd installed replaced the previous version.

    Description:

    • Agent.jar - canRedefine and canRetransform settings are
      both set to true
    • AgentNoRedef.jar - canRedefine setting is set to false (no longer
      used)
    • AgentNoRetrans.jar - canRetransform setting is set to false (no
      longer used)
    • AgentNoRedefNoRetrans.jar - canRedefine and canRetransform
      settings are both set to false. With the introduction of the retransformation
      option in the IBM JVM 1.6 this jar was developed to address performance issues
      being experienced by some clients and replaces the AgentNoRedef.jar and
      AgentNoRetrans.jar


    20.The RTTM Service will not start. Instead, it appears to be stuck and the Status is "IN PROGRESS". What should I do to get the Service started?

    http://support.ca.com/irj/portal/kbtech?docid=596475

    Description:  The RTTM service in APM can get stuck and display in the APM CEM GUI that the status of the service is "In Progress". This status persists across restarts of the Enterprise Manager, and the Start and Stop buttons are not available to click.  Using a database tool (such as pgadmin III or SQL*Plus), access the APM Database, and open the table "ts_monitor_child_service". Look for the item where the column "ts_child_service_id" is "7", and check the value of the column "ts_started" - it will have a value of "2". If the issue persists, contact CA Technologies APM Technical Support for next steps. This could include an upgrade to a later release where certain causes of this condition have been eliminated.
