| Purpose |
| Questions and Answers |
| Which JDBC driver should be downloaded, the Oracle JDBC for Rdb Driver or the Oracle JDBC Driver? What is the difference? |
| Where to download the JDBC for Rdb driver? |
| Which version of the driver should be downloaded? There are versions 7.1.x, 7.2.x. and 7.3.x |
| Does JDBC for Rdb work with JAVA 8? |
| How to install the JDBC for Rdb driver? Is any Oracle Installer needed? |
| Where to find more installation hints? |
| What quotas are required? |
| Where are more information about Java on OpenVMS? |
| Is SQL/Services needed to use the JDBC for Rdb driver? |
| The JDBC for Rdb driver is already installed, and Oracle Support is asking about the version that is installed. How to get this information? |
| What is the difference between the "JDBC for Rdb Native Driver" and the "JDBC for Rdb Native Thin Driver"? |
| How to talk via the Oracle JDBC for Rdb drivers to an Oracle Rdb database from a client that is not on the same node as the database? |
| How to start the JDBC for Rdb Thin Server process? |
| After setting up the JDBC driver, the error message Java JDBC Error: no rdbjdbcshr in java is seen. Why? |
| How to change the default attributes of the RdbThin Server process? |
| A previous version of the Oracle JDBC for Rdb driver had only standard configuration files. Are they still supported? |
| Where to find an example to test the JDBC for Rdb Driver? |
| While starting the RdbJdbcCheckup.class with the option "-t", the following exception is thrown: Exception in thread "main" oracle.rdb.jdbc.common.RdbException: Io exception : connection refused |
| The RdbJdbcCheckup test is running, but a bunch of SYSTEM-I-EMULATED messages are coming up. Why? |
| How to specify the connection string to use the JDBC for Rdb Driver? |
| Oracle Support asked to switch on JDBC Tracing. How to do that? |
| Though the trace value 0x4 has been set there are no SQL statements traced. What is the cause? |
| How to send the trace information to a file? |
| How to get the Rdb debug flags information for applications that connect to the Rdb database using the JDBC for Rdb driver? |
| Is it possible to run more than one version of the JDBC for Rdb driver on the same system at the same time? |
| After changing a pool of Thin Server Processes to a pool of MP Thin Server Processes only one server process out of the pool seems to be used. Is that not supported? |
| After reading the documentation it is still unclear what are the differences between a Thin Server, a Multi-Process Thin Server and a Pool Server. |
| Is there a way to preattach an executor/server to the database to avoid the overhead of attach/deattach? |
| What is the best way to ensure that the JDBC for Rdb server is restarted on reboot? |
| How much is the performance impact with a multi-process thin server connecting to an executor versus a thin server? |
| Is the pool server somehow able to determine which server is the busiest? |
| The pool server and the thin server processes are running under the account which started them. How to achieve that they run under a different acoount? |
| How to manipulate list of byte varying fields in my database? The example in the rdbjdbc_readme.html file shows only how to read BLOBs. |
| The example in note 254991.1 to insert and read BLOBs does not work properly. What is the reason? |
| Can I use the JDBC for Rdb Native Driver together with Forms and Reports? |
| Is the JDBC driver for Oracle Rdb XA compliant? |
| Can we adjust the JDBC srv.idletimeout parameter, default 0, so attaches disconnect when they become inactive? |
