ABAP性能优化的BLOG&NOTE&TCODE(寻找ST12)

原创 Linux操作系统 作者:xxb-xue 时间:2011-02-21 16:15:48 0 删除 编辑

一个不错blog 说明ABAP 性能:

http://blog.sina.com.cn/s/blog_5368b81a0100akh2.html

在SDN 上看到大量关于性能优化一个ST12 ,但是不在目前的系统中(ECC 6.0) 

谁能知道,需要打什么pack,才能使用ST12.

最近从一个朋友从2010 SAP tech 的文档中,看到一个STA TCODE ,听说未来会替代SE30和ST05.



STUN--分析性能的工具(Menu)

Tools -> Administration -> Monitor -> Performance 或者
Tools -> CCMS -> Control/Monitoring -> Performance menu

4.SAP 系统模块常见性能优化的BLOG&NOTE


1. ST05 - Trace requests

2. SE30 - Runtime analysis
3. SE38 -> Environment -> Perfomance examples

If you want to know all then you should start reading, tcodes will not help you.
I can offer you seven blogs:

SQL trace:

SE30

when you read them all, and understand them, then I would maybe
send you some more unpublished one :)

Transaction code for performance tuning:

SE30 - ABAP runtime analysis


ST02 - Tune Summary.

ST03 - Workload Analysis (Tuning of buffers,.

ST03N-
ST04 - Database Performance Analysis.
ST05 - Performance Analysis (SQL Trace, etc).

 

ST06 - Operating System monitor.

ST06N-

ST07 - Application Monitor.
ST14 - Application Analysis.

ST02 is for Buffers
ST03 is for Performance
ST04 is for Database

SM04, SM21, SM12, SM13, ST02, ST03, ST06, ST22, ST07, DB12, DB13, DB14, OS07.
