Transaction Count represents the total number of commits
and rollbacks performed during a sample period. This statistic is an indication of how much work is being accomplished within the database. A spike in the transaction rate may not necessarily be bad. If response times stay close to normal, it means your system can handle the added load. Actually, a drop in transaction rates and an increase in response time
may be indicators of problems. Depending upon the
application, transaction loads may vary widely across
different times of the day.
TCount = deltaCommits + deltaRollbacks
deltaCommits: difference of \'select value from v$sysstat where name=\'user commits\'\' between sample end and start
DeltaRollbacks: difference of \'select value from v$sysstat where name=\'user rollbacks\'\' between sample end and start

If we just count Transaction rate by commits and rollbacks , what ever happens to all the read transactions ???
what about the impact these will have on response time etc..???

can you exp.
Can you explain what do you mean "between sample end and start"? Do you mean just pick an arbitrary time to start the query and end the query?

Actually, the end and start time is not actually arbitrary.
This is a part of tuning lesson and usually measured using the utlbstat and utlestat.sql.

I have tried the following query , It is giving the count of the cmmitted or rollback command.
Please confirm, whether output of the query of the committed or rollback transaction or no of times we have run the commit or rollback command.
