On this tutorial, you’ll see how to update your database statistic. Database statistic need to be update in order to accelerate database query on your program or SAP standard program. For example, you need to query data from MSEG table. If MSEG table has may rows data and never been updated its statistics then your program would be running slowly especially when MSEG table rows had been grown rapidly.
To update database statistic, you could use BRCONNECT or BRTOOLS. Actually, BRCONNECT is part of BRTOOLS. I’ll explain how to use both of them. I use my Windows box and use [sid]adm. If you use UNIX box, use ora[sid].
First, let’s try to use BRCONNECT to update MSEG table. Open your MSDOS prompt.
Type command : > brconnect -u / -c -f stats -t MSEG
Explanation :
- – u means using user root (/)
- – c means force without using password
- – f means using function statistics. Another option is checks.
- – t means which table is going to update its statistics. Another option is ALL for all tables.
Now, we are going to look at BRTOOLS to do this task. BRTOOLS are menu based program. Open your MS-DOS prompt. Type BRTOOLS.
Type 7 to choose Database Statistics. Press ENTER.
Type 1 to update database statistics. Press ENTER.
To update MSEG table choose 9 to enter MSEG table name and then press ENTER.
Type C to continue to next step, running update database statistic process.
You’ll see summary of what you are going to do. Type C to continue.
Last confirmation before running update database statistics. Type C to continue.
BRTOOLS update database statistics has been completed successfully. Type C to continue and back to update database statistic menu.
Type B to go back to BRTOOLS main menu.
Type 9 and then ENTER to exit from BRTOOLS menu.
That’s all for now. Now you know how to update your database statistic. Hope this tutorial work for you. See you on the next tutorial.
