MIN_AUTH_SERVERS

2.234 MIN_AUTH_SERVERS

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
Basic	No
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.
