MIN_AUTH_SERVERS specifies the minimum number of authentication servers in the authentication pool. This pool authenticates user connections when client applications connect to Database Resident Connection Pooling (DRCP).

Property Description

Parameter type

Integer

Default value

If the ENABLE_PER_PDB_DRCP initialization parameter is set to true, then the default value for MIN_AUTH_SERVERS is 0 in each PDB.

If the ENABLE_PER_PDB_DRCP initialization parameter is set to false, then the default value for MIN_AUTH_SERVERS is 1 in the CDB root.

Modifiable

ALTER SYSTEM

Modifiable in a PDB

Yes, according to the following guidelines:

  • When the ENABLE_PER_PDB_DRCP initialization parameter is set to true, MIN_AUTH_SERVERS can be modified only at the PDB level; it cannot be modified for the CDB root.

  • When the ENABLE_PER_PDB_DRCP initialization parameter is set to false, MIN_AUTH_SERVERS can be modified only for the CDB root; it cannot be modified at the PDB level.

Range of values

Minimum: 0

Maximum: MAX_AUTH_SERVERS or PROCESSES, whichever is the lesser value

Oracle RAC

Different instances can use different values.

The value of this parameter must be less than or equal to the values of both the MAX_AUTH_SERVERS initialization parameter and the PROCESSES initialization parameter. The MAX_AUTH_SERVERS parameter specifies the maximum number of authentication servers in the authentication pool. The PROCESSES parameter specifies the maximum number of operating system user processes that can simultaneously connect to Oracle.

Note:

This parameter is available starting with Oracle Database release 19c, version 19.10.
