I wrote a batch mq program and an online program.
The batch program is to read vsam file then put it
into MQ(sequently peocessing),the online program read
record from MQ.for each record need to update online
VSAM file.I found It cost about 0.001second for each
record processing when total record number is less
than 100,but it cost more than 5 seconds when total
record is more then 1000.I also find there are about
42 task for this online program running at same time.
I think the root reason is that too many task run at
same time(because they need update vsam file may wait
for other).

Hello,

If you talk with your CICS System Programmer(s) there is a way to control the number of concurrent executions of a transaction (if my memory is correct).
