TREX Engine not working in PI

Hi Experts ,

My team has configured TREX with PI, to monitor PI messages.

I can see that , unlike the Integration Engine which has about 190000 messages, there were no messages indexed for Adapter Engine, is this expected ?

Am I missing some important configuration / settings.

Please suggest.

    Hi Arnab,

    For PI 7.1 with EHP1, then you can following threads to search the messages using Trex:


    It should be there, sicne Trex server is installed.

    Else, you have to write the ABAP code for search:


    Also, if you have configured correctly cross check the steps below:

    The global settings is valid for all components u have selected for indexing. You can use the default value itself.

    ther are parameters like

    1) Maximum number of messages per package to be transferred to the TREX server

    2) Maximum size in KB of message packages transferred to the TREX server

    3) Time interval in minutes for the periodic transfer of message packages to the TREX server for indexing

    4) Time interval in hours for the periodic reorganization of the index of a component on the TREX server

    5) Time period in days for the retention period of messages in the index

    6) Time interval in minutes for the periodic processing of the TREX queue

    7) Maximum number of entries for processing in the TREX queue

    Also ther are filters available. if the filter is empty then all the messages will get indexed and will be available in search,

    if u enter any details in filter option, then that particular interface only be indexed and only indexed messages will be available for content base search. The use of filter will improve the performance in case of large message flow and also it will save your hardware resources. but make sure that all required interfaces will be available in filter or other wise will searching you will get confused.

    Also, check sap note: 1266924 if everything is fine!

    Hope this helps.

    The configuration of TREX required for adapter engine(java) is different from integration engine.

    Please check the TREX service in visual administrator and see if the name server address has configured there.

    Also from RWB-> index administration activate the indexing if not done.

    check below for details-

    hope this helps.
