1.263 PARALLEL_MIN_SERVERS

PARALLEL_MIN_SERVERS is the number of parallel execution processes Oracle creates when the instance is started. These processes will be kept alive to service parallel statements.
Property Description

Parameter type

Integer

Default value

CPU_COUNT * PARALLEL_THREADS_PER_CPU * 2

Modifiable

ALTER SYSTEM

Modifiable in a PDB

No

Range of values

Default value to the value of PARALLEL_MAX_SERVERS

Basic

No

Oracle RAC

Multiple instances can have different values.

Note:

This parameter applies to parallel execution in exclusive mode as well as in an Oracle Real Application Clusters environment.

Note:

When the PROCESSES initialization parameter is set to a value that is lower than the documented default value for the PARALLEL_MIN_SERVERS parameter in the table above, the database sets the default value of PARALLEL_MIN_SERVERS to a value that is lower than the documented default value. The lower default value enables the database to start service processes and allows user processes to connect to the database.
