Re: Oracle Fehler für Gurus

Hei,

ich kann Dir nur den untenstehenden Text aus dem Oracle Technet
anbieten. Vielleicht hilfts Dir weiter.

Ciao, Uwe

Restrictions on Connections
When you link a program using the single-task driver, it can only connect to one database at a time, which is implicitly the default database. If another database is desired, it must be explicitly referenced in the OLOG call. Additional connections to the same database, if desired, must be made using OLOG.
There are two communications modes of connecting to an Oracle database, blocking and non-blocking. With the blocking mode, an OCI call returns only when it completes, either successfully or in error. With the non-blocking mode, control is immediately returned to the OCI program if the call could not complete (with ORA-03123 message). In this case, the OCI client can continue to process other statements while waiting to retry the OCI call to the server.

Note: The non-blocking mode is based on a polling paradigm, which means that the client application must check whether the pending call has finished at the server by executing the call again with the same parameters.

See the section "Non-Blocking Mode" for more information about connection modes.
