DRCP_CONNECTION_LIMIT

DRCP_CONNECTION_LIMIT specifies the maximum number of Database Resident Connection Pooling (DRCP) connections for a PDB.

Property	Description
Parameter type	Integer
Default value	In CDB$ROOT: 0 (unlimited) In a PDB: If a persistent value for SESSIONS was explicitly set for the PDB (ALTER SYSTEM SET SESSIONS = n SCOPE={SPFILE|BOTH}), and the PDB was subsequently restarted, then the default value is (10 * SESSIONS). Otherwise, the PDB inherits the value for this parameter from CDB$ROOT.
Modifiable	ALTER SYSTEM
Modifiable in a PDB	Yes
Range of values	0 to operating system-dependent A value of 0 specifies that there is no limit on the number of DRCP connections.
Basic	No
Oracle RAC	Different instances can use different values.

DRCP_CONNECTION_LIMIT is a PDB-inherited parameter. The value of this parameter in CDB$ROOT is not a CDB-wide limit. It is the default value for each PDB.
