The service context contains three handles as its attributes, that represent a server connection, a user session, and a transaction.

When an application calls OCILogon(), the OCI library initializes the service context handle that is passed to it and creates a connection to the specified server for the user whose username Handles Almost all OCI calls include in their parameter list one or more handles. This data includes information about statement text and bind data, as well as define and describe information for queries. The error handle maintains information about errors that occur during an OCI operation.

OCI_INVALID_HANDLE An invalid handle was passed as a parameter or a user callback is passed an invalid handle or invalid context. Sage Unable To Allocate An Environment Handle Thanks a lot!

If an application needs to maintain multiple user sessions on a database connection, the application requires a different set of calls to set up the sessions and connections. You can allocate the following types of handles with OCIHandleAlloc(): error handle. How to make denominator of a complex expression real?

It translates into a physical connection in a connection-oriented transport mechanism.

This describes how to set up the "odbchelper" program (Streams includes the source for this program which can easily be compiled with whatever ODBC drivers you are using) and how to Figure 2-3 Hierarchy of Handles Text description of the illustration lnoci038.gif Handles lessen the need for global variables. Parameter Types OCI functions take a variety of different types of parameters, including integers, handles, and character strings. OCI_STILL_EXECUTING The service context was established in nonblocking mode, and the current operation could not be completed immediately.

That is, they have a special meaning to Oracle and cannot be redefined. Error Handling OCI function calls have a set of return codes, listed in Table2-3, "OCI Return Codes", which indicate the success or failure of the call, such as OCI_SUCCESS or OCI_ERROR, Other OCI functions provide useful return data in handle attributes after the function completes. http://dssoundware.com/unable-to/email-unable-to-relay-error.php Note: This is not to be confused with cancelling a cursor, which is accomplished by calling OCIStmtFetch() with the nrows parameter set to zero.

Some programming tweaking might be needed to handle cursors properly. This chapter covers the following topics: Overview of OCI Programming OCI Program Structure OCI Data Structures Handles Descriptors OCI Programming Steps OCI Environment Initialization Processing SQL Statements Commit or Rollback Terminating In the case of arrays of indicator variables, the individual array elements should be of type sb2. Access to the cache is serialized if multiple threads try to allocate memory under the same environment handle.

The datatype of indicator variables is sb2. This descriptor--OCILobLocator--is also used for operations on FILEs. The parameter descriptor is the one descriptor type that is not allocated using OCIDescriptorAlloc(). Commit or Rollback An application commits changes to the database by calling OCITransCommit().

For information about using the OCI to write multithreaded applications, refer to "Thread Safety". In this case, the OCI client can continue to process program logic while waiting to retry the OCI call to the server. Most OCI calls return one of these codes. The OCI library allocates a bind handle for each placeholder bound with the OCIBindByName() or OCIBindByPos() function.

After freeing the environment, it is an application programming error to use the environment's handle in a call to an ODBC function; doing so has undefined but probably fatal consequences.When SQLFreeHandle This structure includes an atomic null indicator, plus indicators for each object attribute. This may include warnings. The OCIEnvCreate() and OCIEnvInit() calls have a similar parameter for allocating user memory which has the same lifetime as the environment handle.

To work with a ROWID using OCI release 8 or later, an application can define a ROWID descriptor for a rowid position in a SQL select-list, and retrieve a ROWID into If an OCI application has been initialized in shared mode, all statements that are prepared and executed use the shared subsystem by default. direct path context handle. OCI does not support the PL/SQL RECORD datatype.

The only exception is when setting a process-level attribute for the OCI shared mode. in San Jose, United States Experienced C++ Developer Pando Networks in New York, United States Pando Networks offers employees a generous benefits package which includes health and dental care, short and
