Advanced CORBA(R) Programming with C++ by Michi Henning, Steve Vinoski

By Michi Henning, Steve Vinoski

This needs to be the most effective CORBA books that i've got learn. It has helped me debug code and fasten a few rather knotty difficulties. i discovered the exposition transparent and simple to stick to, and the index a great tool. i don't believe the authors meant it to be learn cover-to-cover.

If i'm engaged on a CORBA venture I alway prefer to have this booklet handy.

Alternatively, you can execute the SQL DDL that changes the AUTHID of the current user. Different definers can have different privileges, and applications can consist of many classes. So, use the option -definer carefully, making sure that classes have only the privileges they need. 2-22 Java Stored Procedures Developer’s Guide 3 Publishing Java Classes Before calling Java methods from SQL, you must publish them in the Oracle data dictionary. When you load a Java class into the database, its methods are not published automatically because Oracle does not know which methods are safe entrypoints for calls from SQL.

It has a single method named quote(), which returns a quotation from Oscar Wilde. class. Introduction 1-17 Developing Stored Procedures: An Overview Step 2: Load and Resolve the Java Classes Using the utility loadjava, you can upload Java source, class, and resource files into an Oracle database, where they are stored as Java schema objects. You can run loadjava from the command line or from an application, and you can specify several options including a resolver. In the example below, loadjava connects to the database using the default JDBC OCI driver.

To address this issue, several JVM suppliers create native compilers. Native compilers translate Java bytecodes into platform-dependent native code, which eliminates the interpreter step and improves performance. The following describes two methods for native compilation: 1-14 Java Stored Procedures Developer’s Guide The Oracle JVM and Its Components Compiler Description Just-In-Time (JIT) Compilation JIT compilers quickly compile Java bytecodes to native (platform-specific) machine code during runtime.
