Please recommend which the method, BLOB or CWF, shoud I use to support a high volume transactions but simple processing. Requirement is to check the value of one field in the message,'SEQ-NUM', to make a decision for routing the message to any one of two remote queues and log the information of fields RECID, TRAN-DAT, TRAN-TIM, SEQ-NUM,MSG-TYPE, SEND-NO to logfile.
The message length is 1530 byte. Transaction rate is about 150,000 - 183,000 msgs/day and annual growth rate of daily transaction volume is 25%.
The structure of message is :
01 MESSAGE-LAYOUT.
03 MSG-LENGTH PIC 9(02).
03 MSG-TYPE PIC X(04).
03 INT-USER-DATA.
05 REC-ID PIC X(19).
05 TRAN-DAT PIC 9( .
05 TRAN-TIM PIC 9(.
05 SEQ-NUM PIC X(12). **SEQ-NUM(1:2) routing info.
05 MSG-TYPE PIC X(4).
05 SEND-NO PIC 9(1).
05 USER-FIL PIC X(70).
03 USER-DATA-LENGTH PIC 9(02).
03 USER-DATA PIC X(1400).
How much of performance impact between BLOB and CWF processing? Please advise.  |

How were you planning on doing this in a BLOB. You would have to parse the message yourself. And cope with converting everything back to character to check/log it. I think the CWF parser would do a more efficient job than doing all of this in EQSL.

That's only 2 - 3 messages a second, which should not be a problem, with CWF parsing.
Cheers,
