Hi ,

Thanks for the reply.

The trex system has way too many dia , bgd workprocesses than a normal system.

How is the indexing done in trex and how are the different servers in TREX used(queue server , index server....).

Please explain the data , query flow from a ABAP + JAVA server to trex (servers) and back.

Thanks,

Hello,

I got to know that users access all the data in ALL the systems in the landscape with PORTAL.

In that context , what exactly is the TREX ' s use?(iviews,..)

What if TREX is not installed ?

Also from the Abap view point.

Correct me if i am wrong.

Thanks and regards,

Uday.

Hi Uday,

TREX is used as search engine and do not have diag or bgd work process.

TREX can be installed as stand alone engine.

Refer links shared above (help.sap) ,to understand architecture and how TREX is used for searching and configured with different SAP systems.

Hi Ashish ,

Thanks for your reply.

I have found many work processes (100 DIA , 200 BGD ) in trex administration tool which i get through ./TREXadmin.sh. Are these processes NOT TREX'S?

Please find the screenshot attached.

Hello Uday,

These are processes of SAP system with which TREX is configured.

RFC server, Queue server, Preprocessor, Index server, Name server are important server/processes in TREX.

Is it BI system and BIA configured in it.?

In your TREXADMIN tool, Landscape -> Services -> Threads : will show you all TREX threads.
