CONNX JDBC Connection String Parameters
The following table lists the CONNX JDBC connection string parameters that can be used when opening a connection to the CONNX JDBC Driver.

Connection Parameter Name | Description
APPLICATION | Specifies the CONNX application to use when connecting. The application can be a database within the CDD or within an entire collection of databases.
CLIENTID | This is a user-defined identifier sent from the CONNX Client to the CONNX Server. It can be used to run custom procedures on the server during a connection. Use of this setting will affection connection pooling, as any identifier used here is part of the unique signature of a connection.
CNXSESSIONID | This is a user-defined identifier sent from the CONNX Client to the CONNX Server. It can be used to run custom procedures on the server during a connection. Use of this setting will not affect connection pooling. A special CNXSessionID of "BYPASSCAP" will enable connections that exceed the JDBC Maximum parallel connection cap.
DBKEY | This is an Rdb-only feature. The only valid option is ATTACH. If DBKEY=ATTACH is specified, then Rdb DBKEYS is not reused throughout the lifetime of a connection.
DBREADONLY | A list of databases in the CDD, separated by commas, which are treated as read only.
DBREADWRITE | A list of databases in the CDD, separated by commas, which are treated as read/write.
DD | The name of the JDBC data source. Required. (deprecated)
DSN | The name of the JDBC data source. Required.
EXCLUSIVE | Connect to all databases in "exclusive" mode.
GATEWAY | The name or ID address of the JDBC Server. Required.
NODE | The name of the server to connect to. This option is only useful when connecting to a CDD that only has one data source in it.
OEM | Key used for OEM redistributors.
PORT | The port that the JDBC Server is configured to listen to. The default is 7500.
PASSWORD | The CONNX password.
PWD | The CONNX password (deprecated)
READONLY | This option connects to all databases in the CDD in read only mode.
RPC | The name of a CONNX RPC to execute right after a connection has been established.
RPCBUFFERSIZE | The size of the buffer used to send data between the JDBC driver and the JDBC server. The default value is 100000 bytes.
SSL | Enable TLS/SSL encryption for this JDBC Connection. Valid values are "true" and "false"
UID | The CONNX UserID (deprecated)
USER | The CONNX UserID.
VIEWCHECK | A logical connection is made to the CDD without physically connecting to any of the data sources. All queries will return 0 rows. The defaul value is false.
