The process of changing the Messaging System Queue thread properties has changed with XI 3.0 SP19 / XI 7.0 SP11. Previously the queue consumer threads were adjusted in the property –

     messaging.connections

of the J2EE service

    SAP XI AF Messaging

————————

Since XI 3.0 SP19/ XI 7.0 SP11 this has changed to the property –

   messaging.connectionDefinition

of the  service

    XPI Service: SAP XI AF Core.

—————————————–

(N.B.,

the Industry Standard Adapters (e.g., CIDX, RNIF) use the property –

  messaging.connectionParams

of the service

  XPI Service: Messaging System)

—————————————–

The example below adds a new property set for the RFC Adapter. This is appended after the global AFW entry,

i.e.,

(name=global, messageListener=localejbs/AFWListener, exceptionListener=localejbs/AFWListener, pollInterval=60000, pollAttempts=60, Send.maxConsumers=5, Recv.maxConsumers=5, Call.maxConsumers=5, Rqst.maxConsumers=5), (name=RFC_http://sap.com/xi/XI/System,  messageListener=localejbs/AFWListener, exceptionListener=localejbs/AFWListener, pollInterval=60000, pollAttempts=60, Send.maxConsumers=8, Recv.maxConsumers=8, Call.maxConsumers=12, Rqst.maxConsumers=12)

When adding a new queue property set ensure that a comma separates the sets.

If the requirement is to increase the number of threads to the same amount for all the adapter types then the queue values (e.g., Recv.maxConsumers) in the global property set can be modified.

After changing then ‘Update’, Save and restart the SAP XI AF Core service.

With the introduction of the Queue Separation feature each adapter type has its own queue instance and respective configurable properties. If the system has been upgraded to XI 3.0SP19/ XI 7.0 SP11 then there may be a decrease in system performance because the central AFW queue’s properties :

Synchronous :

   Call.maxConsumers

   Rqst.maxConsumers

Asynchronous :

    Send.maxConsumers

     Recv.maxConsumers

previously had a higher value than the current default 5,

  i.e., see the note :-

#1084161 Performance decrease after applying XI 3.0 SP20 7.0 PS12

new values after the global change to the Adapter consumer thread values

N.B.,

  for > = PI 7.1 systems use the configTool to change the service –

      com.sap.aii.af.svc

property –

      messaging.connectionDefinition

* Industry Standard Adapters,  use the configTool service – com.sap.aii.af.ms.svc

**

ICO scenarios only use the send (i.e., Send and Call) queues

    Hi Kenny,

    i have added below property for JDBC Adapter in NWA(pi 7.1 ehp1), After parameter change the XPI Service: AF Core / XPI adapter is not running.
    What could be the reason?

    (name=JDBC_http://sap.com/xi/XI/System, messageListener=localejbs/AFWListener, exceptionListener=localejbs/AFWListener, pollInterval=60000, pollAttempts=60, Send.maxConsumers=5, Recv.maxConsumers=10, Call.maxConsumers=5, Rqst.maxConsumers=5.

    Regards,
    Raj

      Hi Raj,

      there could be a number of reasons,
      e.g.,
      •     did you add the JDBC property set after the General adapter set?
      •     did you add a closing parenthesis to the JDBC property set?
      •     did you separate the property sets by a comma?

      You should make these changes (for > =PI 7.1) in the configTool then set, update and restart.

      Regards

    Hi Kenny,

    When i tried to edit messaging.connectionDefinition in Config tool. The jave is not coming up since the Global pool parameters are overwritten with custom settings and stdserver.out gave the below error.


    Again after reverting the parameters java had come up.

    Service [com.sap.aii.af.svc] start ================= ERROR =================

    com.sap.engine.frame.ServiceException: <–Localization failed: ResourceBundle=’com.sap.engine.frame.ServiceResourceBundle’, ID=’Instantiating the Adapter Framework MS Connection Registration service (co

    m.sap.aii.af.service.ms.ConnectionRegistration) failed. Reason: java.lang.Exception: The global connection definition is not available..’, Arguments: []–> : Can’t find resource for bundle java.util.Pro

    pertyResourceBundle, key Instantiating the Adapter Framework MS Connection Registration service (com.sap.aii.af.service.ms.ConnectionRegistration) failed. Reason: java.lang.Exception: The global connect

    Your reply is highly solicited.

    Regards,

    This was resolved by adding the 2 properties separated by comma and restarting the complete system.

    Thanks a lot for this blog.

    Cheers!
