Session. gc_pisor = 100
Defines the probability of starting the garbage collection program each time a session is initialized. The calculation formula is as follows: session. gc_probability/session. gc_pisor. for example, 1/100 indicates that a 1% probability starts the garbage collection program. The more frequently session pages are accessed, the smaller the probability is. Recommended value: 1/1000 ~ 5000.
