This structure is used for passing information about a connection from ODPI-C. It is used by the function dpiConn_getInfo().

Fields

dbDomain: *const c_char

A pointer to the name of the Oracle Database Domain name associated with the connection, encoded in the encoding used for CHAR data. This is the same value returned by the SQL expression SELECT VALUE FROM V$PARAMETER WHERE NAME = 'db_domain'.

dbDomainLength: u32

Contains the length of the [dpiConnInfo.dbDomain] member, in bytes.

dbName: *const c_char

A pointer to the Oracle Database name associated with the connection, encoded in the encoding used for CHAR data. This is the same value returned by the SQL expression SELECT NAME FROM V$DATABASE. Note the values may have different cases.

dbNameLength: u32

Contains the length of the [dpiConnInfo.dbName] member, in bytes.

instanceName: *const c_char

A pointer to the Oracle Database instance name associated with the connection, encoded in the encoding used for CHAR data. This is the same value returned by the SQL expression SELECT SYS_CONTEXT('USERENV', 'INSTANCE_NAME') FROM DUAL. Note the values may have different cases.

instanceNameLength: u32

Contains the length of the [dpiConnInfo.instanceName] member, in bytes.

serviceName: *const c_char

A pointer to the Oracle Database service name associated with the connection, encoded in the encoding used for CHAR data. This is the same value returned by the SQL expression SELECT SYS_CONTEXT('USERENV', 'SERVICE_NAME') FROM DUAL.

serviceNameLength: u32

Contains the length of the [dpiConnInfo.serviceName] member, in bytes.

maxIdentifierLength: u32

Specifies the maximum length of identifiers (in bytes) supported by the database to which the connection has been established. See Database Object Naming Rules. The value may be 0, 30, or 128. The value 0 indicates the size cannot be reliably determined by ODPI-C, which occurs when using Oracle Client libraries 12.1 (or older) and also connected to Oracle Database 12.2, or later.

maxOpenCursors: u32

Specifies the maximum number of cursors that can be opened. This is the same value returned by the SQL expression SELECT VALUE FROM V$PARAMETER WHERE NAME = 'open_cursors'.

serverType: u8

Specifies the type of server process used by the connection. This value will be one of the values in the enumeration dpiServerType.
