Look at the parameters

Modify the parameter principle   On an existing basis Every time 0.1* base float

After modifying parameters, the sap<sid> Test parameters under

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
