DB2 V9 for z/OS installation ohne Java support?

Hallo zusammen,

DB2 V9 for z/OS und neue Feature (OSC Optimization Service Center, Data Studio, XML Schema Registration and Removal, DECFLOAT Column Attribute, DB2-supplied Java Stored Procedures, WebSphere Developer) stellen neue Funktionalität zur Verfügung, die aber auch weitere Anforderungen an die z/OS Plattform (inkl. USS) stellen.

Das bedeutet nun …. [aus dem Announcement] …

"z/OS Application Connectivity to DB2 for z/OS consists of a component known as the DB2 Universal Database Driver for z/OS, Java Edition. It is a pure Java, type 4 JDBC driver designed to deliver high performance and scalable remote connectivity for Java-based enterprise applications on z/OS to a remote DB2 for z/OS database server. "

und

"Applications or stored procedures that are written in Java, such as those that use the JDBC or SQLJ interfaces to DB2, require IBM SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-I56) (SDK1.4.2), at run time. "

und

"WebSphere Studio Enterprise Developer V5.1.2 (5724-B67), which has the following program requirement of its own: IBM SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-I56) (SDK1.4.2)."

und

"Applications or stored procedures that are written in Java, such as those that use the JDBC or SQLJ interfaces to DB2 for z/OS, require IBM SDK for z/OS, Java 2 Technology Edition V1.4 (SDK1.4.2). Two editions are available: the 31-bit edition (5655-I56) and the 64-bit edition (5655-M30). However, the 64-bit edition does not support persistent reusable function.

Sharing class objects between Java virtual machine (JVM) processes that run in the same address space requires IBM SDK for z/OS, Java 2 Technology Edition V1.4 (SDK1.4.2). Two editions are available: the 31-bit edition (5655-I56) and the 64-bit edition (5655-M30). These are independent products that can coexist on the same z/OS system. "

und

"Use of decimal-float conversion capability requires IBM SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-I56) (SDK1.4.2) at run time. "

und

"In addition, use of XML schemas requires IBM 31-bit SDK for z/OS, Java 2 Technology Edition"

Wenn kein Java Support installiert wurde, dann muß auf folgende Funktionen verzichtet werden:

Java procedure processing routines
[tt]- ALTER_JAVA_PATH
– DB2_INSTALL_JAR
– DB2_REMOVE_JAR
– DB2_REPLACE_JAR
– DB2_UPDATEJARINFO
– INSTALL_JAR
– REMOVE_JAR
– REPLACE_JAR[/tt]

[tt]Java-enabled routines
– Text search routine
  – SYSTS_ENCRYPT
– XML routine
  – XSR_COMPLETE
– Optimization Service Center routines
  – EXPLAIN_SQL
  – OSC_EXECUTE_TASK[/tt]

Wer kennt weitere Aspekte, Pro’s und Contra’s zur Installation und Nutzung von Java unter z/OS?

Viele Grüße
