SAP 内存参数调优过程

ST02

点看看下红色的 

 

看下参数

修改参数原则  在现有基础上 每次0.1*基数 浮动

修改参数后在sap<sid>下进行检测参数

Maximum shared memory size > 20G
***ERROR: Size of shared memory pool 40 too small
================================================================
SOLUTIONS: (1) Locate shared memory segments outside of pool 40
               with parameters like: ipc/shm_psize_<key> =0

SOLUTION: Increase size of shared memory pool 40
          with parameter: ipc/shm_psize_40 =486000000
