MQ is not communicating with the TDQ, it is probably communicating with a program running in CICS which writes to the TDQ causing CICS to trigger another transaction based upon the TDQ's trigger level. |

Hi,
Thanks for the response. as you said my application is reading from TDQ using READQ. another midrange application sends message to TDQ via MQ. want to know how this communication happens between MQ and TDQ.
any info/help will be a great help for me.
Thanks,
Abhishek |

did You try to understand the previous reply???
unless the acronyms TDQ and MQ mean something else to You
TDQ and MQ are completely unrelated things,
the only thing they have in common is the Q as last letter of the acronym
see
publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DFHP3C00/4.8?SHELF=DFHASJ00&DT=20070619105120
for the TRANSIENT DATA CICS concept
as an approximation a TDQ in CICS is a sequential(flat) file
after Your program has read a message from MQ it is free ( the program ) to dispose of it ( the message ) in any way
for example
for a batch application to write it to a sequential(flat) file
for a CICS transaction to write it to a TRANSIENT DATA DESTINATION(QUEUE) file |
