Re: IMS - DFSRRC00 vs ODBA
VSAM? No IMS / DB2 overhead. Datacom? PS-FB.

Re: IMS - DFSRRC00 vs ODBA
I think in most cases, the database will be local. Assuming local, is access faster using DFSRRC00 or ODBA. If not local, what is faster? Thnx, Pierre -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: IMS - DFSRRC00 vs ODBA
If the database is local, ODBC will slow it down. DFSRRC00 is batch oriented ( may run with TM/DBCTL as well). The question you need to answer is where the database is.
