    DB2 CONNECT configure and Sysplex support

    Hi, All,
    I have question on DB2 CONNECT configure.
    We installed DB2 ESE V8 FixPak 14 o AIX .
    When we set up the connection to DB2 Mainframe.
    We just catalog node and DB directory without DCS.
    From what I know, DB2 conenct needs to set up node, dcs and db
    directories.

    Why DB2 CONNECT can connect to DB2 mainframe without the DCS?

    Another issue on the Sysplex support on the above db2 connect
    configuration.
    We have set DB2CONNECT_IN_A PP_PROCESS=NO ,
    But i can still see reroute.
    I checked IBM http://www-1.ibm.com/support/docview...id=swg21253021
    It has the difference on DB2 Connect and gateway.
    Is my above set is gateway or DB2 Connect?


    In case the client applications are running locally on the same
    physical machine as DB2 Connect, you need to set
    DB2CONNECT_IN_A PP_PROCESS=NO to force the local clients to run in an
    agent so as to utilize Sysplex support.

    db2set DB2CONNECT_IN_A PP_PROCESS=NO

    db2stop

    db2start


    However, if you want to disable DB2 Connect Sysplex support on your
    gateway, you can simply catalog a DCS database without specifying the
    Sysplex in the parameter list and re-catalog the DCS database as your
    database alias. You can also turn off Sysplex in V8 by setting the DB2
    registry variable DB2SYSPLEX_SERV ER to zero, but this variable is
    deprecated in DB2 Connect V9. By default this variable is set to a
    nonzero value in DB2 Connect V8.

    thanks,

      As for your first question, are you certain that you are connecting to
      the mainframe? Could it be that you are connecting locally?

          Hi, Larry,
          I am sure it can connect to mainfrmaw withour DCS directory.
          thanks,
