    5. CA Wily Technical Advisory: Native Memory Leak on IBM Java 1.6 when using -javaagent TEC576360

    http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec576360.aspx

    Description:
    October 2011 - CA Wily has become aware of a potential issue on IBM Java 1.6 where an application under management may experience severe native memory overhead. This technical advisory describes the affected versions and platforms in more detail, and explains what remediation actions are recommended.

     

    6. JMS Webservices invocations messages placed on JMS queues (TIBCO EMS queues) are big and it takes a lot more time than the expected to be processed. TEC595968

    http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec595968.aspx

    Description: Whenever a single running BW process invokes a HTTP or JMS Webservice willy adds a CorID field to SOAP/HTTP/JMS headers and keeps on incrementing its size for each invocation made within that process. This produces big messages in which the body has around 1000 bytes and the header 9000 bytes, due to this CorID field.

    You try to remove this field in SOAP and HTTP headers by adding the following lines to IntroscopeAgent.profile file:

    com.wily.introscope.agent.soapheaderinsertion.enabled=false      
    com.wily.introscope.agent.httpheaderinsertion.enabled=false


    but the problem persists on SOAP over JMS Webservices invocations, messages placed on JMS queues (TIBCO EMS queues) which are big and it takes a lot more time than the expected for them to be processed.

     

    7. TIM and SSLv3 Poodle Vulnerability TEC1344045

    http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec1344045.aspx

    Description:
    Recently, RedHat has announced a security vulnerability in SSLv3 protocol, commonly referred to as ‘POODLE’. See the following link for information:

    https://access.redhat.com/articles/1232123

    CA has determined TIM Admin UI application (TIM’s webserver) is impacted with this vulnerability. Additionally, communication between the APM CE (CEM) TIM appliance software and the APM Enterprise Manager is affected if SSL communication is enabled between the two components.

     

    8. 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? TEC596475

    http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec596475.aspx

    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.

    15. How to Configure CA APM to use LDAP Authentication (Introscope and APM CE) TEC595290

    http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec595290.aspx

    Description: CA APM gives you choices for securing and authorizing access to some or all of the features and domains of the Enterprise Manager and Workstation. Using LDAP, you can authenticate user and group access with CA APM while maintaining user and group authorization in local configuration files.

    There are 3 ways to secure CA APM

    Local  - Users and groups are both authenticated and given authorization via local configuration files maintained on the Enterprise Manager server.

    LDAP  - Users and groups are authenticated by LDAP directories but authorized by local configuration files maintained on the Enterprise Manager server or CA EEM.

    EEM  - Users and groups are both authenticated and authorized by a CA EEM (CA Embedded Entitlements Manager) server for CA APM activities.

    This article discusses how you can integrate CA APM with your own LDAP directory for authentication to the APM Workstation and Enterprise Manager.

     

    16. How to set up JBoss 6 EAP with the Introscope Agent and see JMX metrics TEC606597

    17. MQ Agent cannot connect to MQ Server. ssl handshake failure. Reason code 2397 MQRC_JSSE_ERROR TEC606483

    http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec606483.aspx

    Description: The MQ Agent fails to connect to the MQ Server when using SSL set to Required Client Authentication.

    When the SSL channel is configured for non-required client authentication, it allows full connectivity, but when the channel is set to required client authentication the connection fails.

    Note that the functionality works even when not using SSL.

    When SHA or MD5 is configured on channel APM.SSL.SVRCONN, the Client/MQ server connection negotiation throws a JSSE exception. This occurs even when the MQ server certificate has been added to the client and the client certificate has been added to the server.

    The following messages are logged in the Agent Log:

    ERROR] [com.wily.powerpack.websphereMQ.agent.MQMonitor.TracerDriverThread] MQMonitor: For configuration instance MQAPMTST@test_dev_machine and the drivers(namelist,cluster) an error occurred in sending query to MQ. The target MQ (test_dev_machine:port#) may be down. Reason code 2397 MQRC_JSSE_ERROR

    $ openssl s_client -connect test_dev_machine :port# -prexit CONNECTED(00000003)

    14815:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188
