Error description

  • The embedded CMIS product changed the
    com.ibm.xml.xlxp2.api.util.encoding.DataSourceFactory.bufferLeng
    th property from the default of 64K to 2K, which can cause
    performance issues during XML serialization of numerous
    synchronous Advanced Integration service (AIS) requests.
    
    
    You can see the performance impact in a Java core as a large set
    of blocked threads on "com/ibm/bpm/sca/core/SCARuntime":

Local fix

  • Manually increase the
    com.ibm.xml.xlxp2.api.util.encoding.DataSourceFactory.bufferLeng
    th property to 64K or significantly larger than 2K to provide
    the buffers required for this processing.
    
    
    1. Open the cmis.properties file in a text editor. The
    cmis.properties file is in the following directory of the
    Business Automation Workflow installation  directory:
    /profiles/<NodeProfile>/installedApps/<CellName>/IBM_BPM_CMIS_Si
    ngleCluster.ear/fncmis.war/WEB-INF/classes/cmis.properties.
    2. Add the following line to the cmis.properties file:
    com.ibm.xml.xlxp2.api.util.encoding.DataSourceFactory.bufferLeng
    th=65536
    3. Save and close the file.
    4. Restart the JVM.
