What is definecolumntype?
What is defineColumnType and when should I use it?#N#defineColumnType is an Oracle JDBC extension that provides increased performance in some cases. In prior versions of Oracle JDBC, all of the drivers benefited from calls to defineColumnType but beginning in 10.1.0 the Thin driver no longer needs the information provided. The Thin driver achieves maximum performance without calls to defineColumnType. The OCI and Server-Side Internal drivers still get better performance when the application uses defineColumnType.#N#If your code is used with both the Thin and OCI drivers, you can disable the defineColumnType method when using the Thin by setting the connection property disableDefineColumnType to "true". This will make defineColumnType a NOOP. Do not set this connection property or else set it to "false" when using the OCI or Server-Side Internal drivers.#N#Define column type may also be used to change the type of the data. Or to limit the size of variable length data.#N#There is a new variation of this with a 4th parameter for form_of_use.
What are the different types of JDBC drivers?
While all Oracle JDBC drivers are similar, some features apply only to JDBC OCI driver s and some apply only to the JDBC Thin driver.#N#JDBC Thin client-side driver: This is a JDBC Type 4 driver that uses Java to connect directly to Oracle. It implements Oracle's SQL*Net Net8 and TTC adapters using its own TCP/IP based Java socket implementation. The JDBC Thin driver does not require Oracle client software to be installed, but does require the server to be configured with a TCP/IP listener. We recommend all of our customers to use JDBC Thin driver as most of the new features are developed only on JDBC Thin driver. Because it is written entirely in Java, this driver is platform-independent.#N#JDBC Thin server-side driver: This is another JDBC Type 4 driver that uses Java to connect directly to Oracle. This driver is used internally within the Oracle database. This driver offers the same functionality as the client-side JDBC Thin driver (above), but runs inside an Oracle database and is used to access remote databases. Because it is written entirely in Java, this driver is platform-independent.#N#JDBC OCI client-side driver: This is a JDBC Type 2 driver that uses Java native methods to call entry points in an underlying C library. That C library, called OCI (Oracle Call Interface), interacts with an Oracle database. The JDBC OCI driver requires an Oracle client installation of the same version as the driver.#N#The use of native methods makes the JDBC OCI driver platform specific. Oracle supports Solaris, Windows, and many other platforms.#N#This JDBC OCI driver is available for install with the OCI Instant Client feature, which does not require a complete Oracle client-installation. Please refer to Oracle Call Interface for more information.#N#JDBC Server-Side Internal driver: This is another JDBC Type 2 driver that uses Java native methods to call entry points in an underlying C library. That C library is part of the Oracle server process and communicates directly with the internal SQL engine inside calls and thus avoiding any network traffic. This allows your Java code running in the server to access the underlying database in the fastest possible manner. It can only be used to access the same database. The use of native methods makes the JDBC Server-Side Internal driver platform specific. This server-side internal driver is fully consistent with the client-side drivers and supports the same features and extensions.
What is JDBC API?
The JDBC API provides a call-level API for SQL-based database access .#N#JDBC technology allows you to use the Java programming language to exploit "Write Once, Run Anywhere" capabilities for applications that require access to enterprise data. With a JDBC technology-enabled driver, you can connect all corporate data even in a heterogeneous environment.#N#—Refer to java.sql for various JDBC specs (4.3, 4.2, 4.2, etc.,) summary in JDK 11#N#—Refer to complete JDBC specs at jcp.org
Which is faster, OCI or Thin?
Which is faster, the Thin driver or the OCI driver?#N#As always, it depends. There are some applications where the the Thin driver is faster, some where the OCI driver is faster. As of 10.1.0, the Thin driver is probably slightly faster than the OCI driver. In cases when the client and server are the same type of hardware and OS, the OCI driver puts a little less load on the RDBMS, even though the Thin client is faster. The differences are usually small, less than 10%. Most of our customers use the Thin driver because of its easier administration. Your mileage may vary.
What is DBMS_LOB.ERASE doing?
What is DBMS_LOB.ERASE doing?#N#It's just "clearing" a segment of the clob. It does *not* shorten the CLOB. So the length of the CLOB is the same before and after the ERASE. You can use DBMS_LOB.TRIM to make a CLOB shorter.
What is the system property of Oracle.DMS.Console.DMSConsole?
There is a system property oracle.dms.console.DMSConsole. If that property is not set then D MS is active. If it is set to oracle.dms.instrument_stub.DMSConsole, then a stub implementation is used, which effectively disables DMS. One way for an application to disable it would be to call
Does Oracle require JDBC driver?
