MAX_AUTH_SERVERS

2.198 MAX_AUTH_SERVERS

MAX_AUTH_SERVERS specifies the maximum 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	`25`
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`, `MAX_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`, `MAX_AUTH_SERVERS` can be modified only for the CDB root; it cannot be modified at the PDB level.
Range of values	Minimum: `MIN_AUTH_SERVERS` or `1`, whichever is the greater value Maximum: operating system-dependent
Basic	No
Oracle RAC	Different instances can use different values.

The value of this parameter must be greater than or equal to the value of the MIN_AUTH_SERVERS initialization parameter, which specifies the minimum number of authentication servers in the authentication pool. The exception is when MIN_AUTH_SERVERS = 0. In this case, the value of MAX_AUTH_SERVERS must be greater than or equal to 1.

Note:

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