Cognos Reporting Fails with CCL-BIT-0016 Error

Troubleshooting


Problem

A few charts in IBM Social Media Analytics show CCL-BIT-0016 or CCL-BIT-0006 error messages in the Reporting UI due to slow network and improper timeout setting.

Symptom

Checking the Cognos BI cogserver.log (default location /opt/ibm/cognos/c10_64/logs/), the following entries or similar can be found:


    Failure CCL-BIT-0016 The request document contains an XML syntax error at line 1, column 1. Code: -1 CCL-BIT-0016 The request document contains an XML syntax error at line 1, column 1. Code: -1Invalid document structure
    Failure CCL-BIT-0006 The connection closed before the request is processed. If you are using WebSphere Application Server, to reduce the frequency of this error, increase the Persistent Timeout parameter for the Web container transport chains in the administrative console. Increase the time in 10-15 second intervals until the error no longer or rarely occurs. CCL-BIT-0006 The connection closed before the request is processed. If you are using WebSphere Application Server, to reduce the frequency of this error, increase the Persistent Timeout parameter for the Web container transport chains in the administrative console. Increase the time in 10-15 second intervals until the error no longer or rarely occurs.

Cause

This is caused by slow networking connectivity or poor system performance.

Resolving The Problem

By default, persistentTimeout for eWas is set to 30 seconds. This should be increased if the system or network is slow.

1. Logon to UI node as cciusr

2. Edit server.xml under <SMA_INSTALL_PATH>/was_sma/ewas/profiles/sma1Profile/config/cells/sma1_cell/nodes/sma1_node/servers/sma1

By default: /local/ibm/cognos/ci/coninsight/was_sma/ewas/profiles/sma1Profile/config/cells/sma1_cell/nodes/sma1_node/servers/sma1


3. Locate the following entry that contains persistentTimeout attribute:
    <transportChannels xmi:type="channelservice.channels:HTTPInboundChannel" xmi:id="HTTPInboundChannel_1183077764084" name="HTTP_1" discriminationWeight="10" maximumPersistentRequests="100" keepAlive="true" readTimeout="60" writeTimeout="60" persistentTimeout="30" enableLogging="false"/>
4. Set pesistentTimeOut value to 90 seconds, and save the file:
    <transportChannels xmi:type="channelservice.channels:HTTPInboundChannel" xmi:id="HTTPInboundChannel_1183077764084" name="HTTP_1" discriminationWeight="10" maximumPersistentRequests="100" keepAlive="true" readTimeout="60" writeTimeout="60" persistentTimeout="90" enableLogging="false"/>
5. Restart SMA services for the change to take effect.
