OracleDBConsole service start failed @ host IP | name changed.

When host ip, or name changes, an error occurs.

It occurs emctl start service error. To solve this error, step by flowing:

set oracle_sid=mes

mes is the sid of oracle.

emctl start dbconsole

Then, a message "OC4J Configuration issue. C:\oracle\product\10.1.0\Db_1/oc4j/j2ee/OC4J_DBConsole_10.1.3.121_mes not found." is displayed. Copy the fold %ORACLE_HOME%\product\10.1.0\Db_1\oc4j\j2ee\OC4J_DBConsole_cci-r3_mes to %ORACLE_HOME%\product\10.1.0\Db_1\oc4j\j2ee\OC4J_DBConsole_10.1.3.121_mes and try start service again.

emctl start dbconsole

Another message "EM Configuration issue. C:\oracle\product\10.1.0\Db_1/10.1.3.121_mes not found." is returned. Copy fold %ORACLE_HOME%\product\10.1.0\Db_1\cci-r3_mes to %ORACLE_HOME%\product\10.1.0\Db_1\10.1.3.121_mes. and restart service again. Service will start successfully.

CookSwing

CookSwing is a library which builds Java Swing GUI from XML documents. It is under continuously active development, since I make a living by doing Swing GUI :) Unlike many other XUL toolkits, Swing is complete in its capability dealing with Swing and beyond. It is mature and stable. If you like this library, please help spreading the word.

It is a pity that CookSwing, not like SwiXml, can't render object itself, but create a new instance for using. In this condition, I msut create a component by assign a instance (variant) and a xml document, instead of by using new . And I can't specify a public method for redered object to invoke some process.

SwiXml

SwiX^ml, is a small GUI generating engine for Java applications and applets. Graphical User Interfaces are described in XML documents that are parsed at runtime and rendered into javax.swing objects.
