     >>-CALL--SQLJ.REPLACE_JAR--(--'jar-url'--,--'jar-id'--)--------><

Description

jar-url

The URL containing the JAR file to be replaced. The only URL scheme supported is 'file:'.

jar-id

The JAR identifier in the database to be associated with the file specified by the jar-url. The jar-id uses SQL naming and the JAR file is installed in the schema or library specified by the implicit or explicit qualifier.

Usage notes

The SQLJ.REPLACE_JAR stored procedure replaces a JAR file that was previously installed in the database using SQLJ.INSTALL_JAR.

Example

The following command is issued from an SQL interactive session:

     CALL SQLJ.REPLACE_JAR('file:/home/db2inst/classes/Proc.jar' , 'myproc_jar')

The current JAR file referred to by the jar-id myproc_jar is replaced with the Proc.jar file located in the file:/home/db2inst/classes/ directory.
