How to analyse the oracle statspack which is in the html format?

I have a html version of the Oracle Sta开发者_运维百科tspack report. I am trying to interpret the data on the report to extract a number of different values but I'm not sure where to look. In particular, I am trying to find

• the number of queries to the database
• the number of commits
• the number of rollbacks
• writes into the database
• the number of sessions
• the amount of network traffic
• initial volume
• volume increase rate

Anyone with any idea as how to get these values as they are not obvious from the html? Sorry, I can't share the html.

That information should all be in the load profile section at the very top of the Statspack report. Taking this sample report as an example

  % Blocks changed per Read:    1.10    Recursive Call %:     68.39
 Rollback per transaction %:    0.10       Rows per Sort:    250.70

Executes is the number of SQL statements that are executed. In this case, 2,101.9 queries were executed on average per second and 133.74 were executed on average per transaction.

Transactions is the number of transactions (i.e. the number of commits + the number of rollbacks). In this case, there were on average 15.72 per second.

Rollback per transaction % is the percentage of transactions that were rollbacks. Since just 0.10% of the transactions were rollbacks, 99.9% of the transactions were commits. You could combine the that fraction with the total number of transactions to get the number of commits per second and the number of rollbacks per second if you so desired.

For the additional items you're interested in

What does the number of sessions mean to you? Potentially, you want the number of new sessions that are created which would probably be the Logons value, i.e. an average of 7.20 sessions were created every second.

Are you interested in the volume of network traffic or in the amount of time spent waiting on network communication? Statistics like

bytes received via SQL*Net from c        166,752,176      114,213.8      7,267.2
bytes sent via SQL*Net to client         282,458,320      193,464.6     12,309.7

tell you that roughly 159 MB of data was sent to the database from the clients over the duration of the snapshot while roughly 269 MB of data was sent to the clients from the database.

I don't know what you mean by "initial volume" or "volume increase rate". What volume are you measuring? What rate of increase are you measuring?
