IT43130: ALLOW OPTION TO SINGLETHREAD CALLS TO GET SAP FUNCTION TEMPLATES

APAR status

• Closed as program error.

Error description

• When using the SAP Request Node to make outbound BAPI calls, in
  some circumstances the following error may be observed:
  BIP3484E: 'com.sap.conn.jco.JCoException: (108)
  JCO_ERROR_INTERNAL: <FUNCTIONNAME> function could not be queried
  for an unknown reason
  
  javax.resource.ResourceException: com.sap.conn.jco.JCoException:
  (108) JCO_ERROR_INTERNAL:<FUNCTIONNAME> function could not be
  queried for an unknown reason
  
  This is believed to be caused by a threading issue in some
  versions of the JCo library, in order to workaround the problem
  this APAR introduces the environment variable:
  
  MQSI_ADAPTER_SAP_LOCK_GETFUNCTION
  
  When set to any non-null value this causes calls to get the
  function defintion to be single threaded.

  PROBLEM DESCRIPTION:
  When using the SAP Request Node to make outbound BAPI calls, in
  some circumstances the following error may be observed:
  BIP3484E: 'com.sap.conn.jco.JCoException: (108)
  JCO_ERROR_INTERNAL: <FUNCTIONNAME> function could not be queried

  javax.resource.ResourceException: com.sap.conn.jco.JCoException:
  (108) JCO_ERROR_INTERNAL:<FUNCTIONNAME> function could not be
  queried for an unknown reason
  
  This is believed to be caused by a threading issue in some
  versions of the JCo library.
  

Problem conclusion

• The problem may be resolved by updating to the latest version of
  the SAP provided JCo library. If this is not possible, this APAR
  introduces the environment variable:
  
  MQSI_ADAPTER_SAP_LOCK_GETFUNCTION
  
  When set to any non-null value this causes calls to get the
  function definition to be single threaded avoiding the issue.
