Error description

  • Your web request arrives from a web server and DFHWBBLI is
    started directly.  This fails with a DFHPG0001 0C4, but the
    transaction appears to execute anyway.  The DFHPG0001 dump
    slows things down a bit; but it can be suppressed by coding
    the PG0001 in the system dump table (SYD) and putting NOSYS
    to suppress the dump.  The incoming request to CICS may look
    something like this:  GET /APPL/CICS/CSMI/DFHWBTTA/TR01
    where TR01 is the transaction to be invoked.
    .
    CICS TS 3.2 has added the CREATE_POOL call which stores a
    token in the wrb, but then a GET_TOKEN is done and it also
    stores the token in the wrb, which overwrites the previous
    token.  Then when the PUT_CONTAINER is done by DFHWBQM
    (called from DFHWBBLI), it is no longer a container token in
    the wrb and DFHPGCR later program checks due to an ebcdic
    value (sysid - in the above example it would be APPL) in the
    WRB_REPOSITORY_TOKEN.

    ****************************************************************
    An HTTP request is sent to CICS via the HTTP Server Plugin
    (DFHWBDLL).  When the request gets to CICS it is processed by
    DFHWBBLI.  DFHWBBLI has to put the contents of the HTTP request
    into various containers for use by the WEB API commands. To do
    this it first creates a container pool and saves the pool token
    in field wrb_repository_token.  Just before the request is saved
    a redundant call is made to the GET_TOKEN function of DFHWBQM.
    That call returns an 8 byte token consisting of the SYSID
    followed by the WRB address.  That 8 byte token is then saved in
    field wrb_repository_token overwriting the container pool token
    that was stored there.  When the request is finally being put
    into a container then two 0C4 abends occur in DFHPGCR followed
    by an 0C4 abend in DFHPGCP.

Problem conclusion

  • DFHWBBLI has been changed to no longer issue the redundant
    GET_TOKEN call.
