interpreting ST03 Tasktype profile

[Former Member]

Dear Gurus,

I am looking at causes of performance deterioration in SAP. I look at ST03 tasktype profile but there are some terms I do not quite understand the meaning. Pls can you throw some light.

1. DB Requests. what does this numner indicate? What is considered a DB request?

2. Buffer Calls. What buffer is it refering to? DB buffer? Which DB buffer then?

3. Physical DB Calls. What does this mean?

Thank you in advance.

1. A request to the database to access data - maybe read write, update

2. The database finds the requested data in the SAP buffers. This is quick and so good. See ST02 Tables, Generic key and Single record.

Also ST10

3. Oh dear, the data is not in the buffers so the database goes and reads the physical disks. This is slow and so bad.

So 1. is made up of 2. and 3.
