PROCESSES
PROCESSES specifies the maximum number of operating system user processes that can simultaneously connect to Oracle.
| Property | Description |
|---|---|
| Parameter type | Integer |
| Default value | The value is derived, and it typically depends on the number of cores reported in the alert log. |
| Modifiable | No |
| Modifiable in a PDB | No |
| Range of values | 80 to operating system dependent |
| Basic | Yes |
| Oracle RAC | Multiple instances can have different values. |
The value for this parameter should allow for all background processes such as locks, job queue processes, and parallel execution processes.
The default values of the SESSIONS and TRANSACTIONS parameters are derived from this parameter. Therefore, if you change the value of PROCESSES, you should evaluate whether to adjust the values of those derived parameters.
