The # shmmax kernel parameter defines the maximum value of a single shared memory segment, if the parameter setting is less than the Oracle SGA setting

# then SGA will be allocated multiple shared memory segments. This can become a performance burden and cause system problems in busy systems.

# if the shmmax parameter is not modified, Oracle may report the following error during startup:

# Starting ORACLE instance (normal)
