Restrictions and Usage Notes → You can only run the CONNECT TARGET, CONNECT CATALOG, and CONNECT AUXILIARY commands if you are at … connect to a different target, catalog, or auxiliary database, then you must start a new RMAN session … . You cannot use the CONNECT CATALOG command when RMAN is in the default NOCATALOG mode, that is,
Purpose → … The CONNECT command avoids this problem. See Also: "cmdLine" for command line connection options
Examples → target database with an Oracle Net service name prod1: % rman NOCATALOG RMAN> CONNECT TARGET sys … then connects to the target through Oracle Net. Because BACKUP is run and no CONNECT CATALOG has … been run, RMAN defaults to NOCATALOG mode: % rman RMAN> CONNECT TARGET sys/change_on_install@prod1 … ; RMAN> BACKUP DATAFILE 7; #
Keywords and Parameters → Syntax Element Description CONNECT AUXILIARY connectStringSpec Establishes a connection between … TSPITR. CONNECT CATALOG connectStringSpec Establishes a connection between RMAN and the recovery … . Otherwise, RMAN defaults to NOCATALOG mode and invalidates the use of CONNECT CATALOG in the session … . CONNECT
CONNECT → Syntax connect::= Text description of connect
CONNECT → Connects a given username to the specified database. Format CONNECT username/password [@ connect-identifier ]; Command Parameters
CONNECT → CONNECT command, the site profile, glogin.sql, and the user profile, login.sql, are executed. CONNECT … [/ password ] The username and password you use to connect to Oracle Database. If you omit username … SQL*Plus. connect_identifier An Oracle Net connect identifier. The exact syntax depends on the … service
mode (IN) → Currently, this function will support only the OCI_DEFAULT mode.
username (IN) → The username. Must be in the encoding specified by the charset parameter of a previous call to OCIEnvNlsCreate().
usrmempp (OUT) → Returns a pointer to the user memory of size xtramemsz allocated by the call for the user.
svchp (OUT) → Address of an OCI service context pointer. This will be filled with a server and session handle. In the default case, a new session and server handle will be allocated, the connection and session will be started, and the service context will be populated with these handles. For connection pooling, a new session handle will be allocated, and the session will be started over a virtual connection from
mfreefp (IN) → Specifies the user-defined memory free function. If mode is OCI_THREADED, this memory free routine must be thread-safe.
errhp (IN/OUT) → An error handle you can pass to OCIErrorGet() for diagnostic information in the event of an error.
Example → The following example demonstrates the use of OCISessionBegin(). This code segment allocates the user session handle, sets the username and password attributes, calls OCISessionBegin(), and then sets the user session into the service context. /* allocate a user session handle */ OCIHandleAlloc((dvoid *)envhp, (dvoid **)&usrhp, (ub4) OCI_HTYPE_SESSION, (size_t) 0, (dvoid **) 0); OCIAttrSet((dvoid *)usrhp,
Comments → Connect through Proxy privilege. See Also: For more information on proxy connections, see Oracle Database
Syntax → sword OCILogoff ( OCISvcCtx *svchp OCIError *errhp );
Syntax → sword OCIServerAttach ( OCIServer *srvhp, OCIError *errhp, CONST text *dblink, sb4 dblink_len, ub4 mode );
mode (IN) → The modes supported are OCI_DEFAULT OCI_CPOOL_REINITIALIZE. Ordinarily, OCIConnectionPoolCreate() will be called with mode set to OCI_DEFAULT. If you wish to change the pool attributes dynamically (for example: change the connMin, connMax, and connIncr parameters), call OCIConnectionPoolCreate() with mode set to OCI_CPOOL_REINITIALIZE. When this is done, the other parameters are ignored.
Comments → The OUT parameters poolName and poolNameLen will contain values to be used in subsequent OCIServerAttach() and OCILogon2() calls in place of the database name and the database name length arguments. See Also: "Connection Pool Handle Attributes"
