INQUIRE DFHTRANSACTION Threadsafe,

We are trying to cut back on TCB Swaps; I notice INQUIRE DFHTRANSACTION to do TCB swap; was wondering if this could be made THREADSAFE? There is a trace entry of TRANSFORMER; not sure what that is....

See trace snippit:


L80AT RM 0302 RMLN EXIT SET_LINK/OK <== L8 here

QR AP D900 XFP ENTRY TRANSFORMER_3 28284924,0E02 <<==QR here,

QR AP 4E00 APCR ENTRY ESTIMATE_CHANGED 2CD987B0,2A8046C8 , 000000A8,LIN

QR PG 1700 PGCH ENTRY INQUIRE_CHANNEL DFHTRANSACTION

QR PG 1701 PGCH EXIT INQUIRE_CHANNEL/EXCEPTION CHANNEL_NOT_FOUND,00000000,0

QR PG 1700 PGCH ENTRY INQUIRE_CHANNEL_BY_TOKEN 2CD987B0

    CICS Development: The trace fragment shown is not INQUIRE DFHTRANSACTION. Transformer 3 is shown. The transformers are part of the processing of function shipped requests, in this case it is preparing to send Channels and Containers data back to the calling region.

    Function shipping across MRO connections is not threadsafe. Function shipping across ipic connections is threadsafe.
