subject: Re: OS Enhancement List

Justin, here is a list of V5R2 enhancements (since you're migrating from 
V5R1) that I created in 2003 by going through various memos to users:

OS/400 
Software enhancements with V5R2 include: 

Performance management improvements:
Dynamic logical partitioning for award-winning 64-bit Linux is added. 
New intuitive iSeries Navigator (formerly known as Operations Navigator) 
workload management tools. 

Adaptive storage virtualization for high availability: 
Mainframe-class availability with switched disk cluster management. 
Self-optimizing, multiple IBM DB2 Universal Database (UDB) images for 
business unit consolidation. 

Microsoft cluster support:  Extensive Windows server management now 
supports MS Cluster Server. 

IASP switched disk:  Supports OS/400 library objects. 

Secure management of e-business:  Industry's first autonomic computing 
enables true single signon. 

High performance Apache Web serving:  With secure sockets and caching 
accelerators. 

Wireless-optimized Web-ready micro-drivers: For simple and pervasive 
operations. 

Capacity Upgrade on Demand (CUoD):  Available with new Models 825, 830, 
840, 870, and 890. 

Database function:  Continuous availability, with independent auxiliary 
storage pools (IASPs), clustering, and journaling enhancements.

Enhancements to Cluster Resource Services and APIs help expand the number 
of Cluster Proven applications, particularly Web serving and legacy/batch 
applications, and make clustering easier for customers. 

Disk Migrate While Active with OS/400 V5R2 further enhances availability 
by supporting concurrent migration of most of the disk subsystem data 
during normal operations. This capability is available through the Start 
ASP Balancing (STRASPBAL) command with options to move data off disk 
subsystems. 

Journal performance can be substantially improved in some environments by 
installing and enabling the new HA Journal Performance (OS/400 option 42) 
feature. Two options enhance journal performance: 
-  Journal Caching can help to substantially reduce the number of 
synchronous disk write operations performed in batch applications and 
reduces overall elapsed batch execution time. 
-  Journal Standby allows you to achieve fast failover in a high 
availability environment and enable journal support on your target iSeries 
machine well in advance of the failover event without incurring the normal 
performance impact associated with journaling. This should be especially 
attractive in shops that need 24x7 operation, have lots of journaled 
tables, and need more rapid failover/role-swap times. 

PASE: AIX V5L support 32 and 64-bit applications and Linux library 
extensions. 

LPAR:  Virtual Gigabit Ethernet connection between OS/400, Linux 
partitions, and Integrated xSeries Servers.  Dynamic processor movement 
for Linux partitions. 

ODBC: Driver for Linux provides access to DB2 UDB for iSeries.


Query Manager and SQL Development Kit 

New with V5R2 
Query Manager and SQL Development Kit for iSeries includes the following 
enhancements at V5R2: 
An SQL Assist function in iSeries Navigator helps you create SQL 
statements that can be used to create and run queries and reports. 
A redesigned query engine that may provide performance improvement for 
many SQL read-only queries. 
Use DB2 UDB for iSeries Predictive Query Governor to control long-running 
queries.

DB2 UDB for iSeries Family SQL Enhancements in V5R2 

JDBC 3.0 (JDK 1.4) 
The Open Group's Distributed Transaction Processing: The XA Specification 
JTA (Java Transaction API) 1.0.1 
ODBC and JDBC drivers for Linux 
User-Defined Table functions 
Savepoints 
Common Catalog Views 
UNION in Views 
IDENTITY columns and ROWIDs 
CREATE TABLE AS (subselect) (support in SQL equivalent to DDS Field 
Reference) 
SQL Source Code Debugger 
Additional SQL Enhancements in conformance with the ISO and ANSI SQL Core 
Standard 


TCP/IP 

For V5R2, many TCP/IP enhancements are implemented with additional 
security features. 
TCP/IP is updated to include: 
- Enhancements to iSeries Kerberos support 
- Enhancements for Digital Signatures 
- Implementation of new Java security standards 
- Firewall friendly virtual private networks (VPN) 
- Enhancements for Cryptographic Accelerators: When installed, it is 
automatically used by the system to off load compute-intensive public-key 
processing to improve cryptographic performance for transactions using 
Secure Sockets Layer (SSL)/Transport Layer Security (TLS). 
- Support for IPv6, the next generation (version) of TCP/IP, via the IPv6 
Application Developer's Platform: IPv6 expands the IP address space from 
32 bits to 128 bits, and is configured through iSeries Navigator by using 
a wizard. 
- Network Quality of Service (QoS) enhancements including inbound 
admission policies and policies stored in Lightweight Directory Access 
Protocol (LDAP) 
- Proxy ARP routing for virtual IP interfaces, allowing the iSeries to 
respond to ARP requests for the virtual IP address 
- Remote Access enhancements including PPPoE (Point to Point Protocol 
(PPP) over Ethernet), and PPP dynamic resource sharing for analog 
connections: Digital Subscriber Line (DSL) traditionally uses existing 
copper telephone lines. With PPPoE in V5R2, the iSeries can exploit DSL 
for Internet access. 
- TCP/IP availability improvements: New configuration attributes are added 
to support Network Fast Cache, TCP/IP Close Connection Logging, and TCP 
minimum retransmit time. 


Java/XML Enhancements 

New versions of the core Java runtime environment and WebSphere 
Application Server are now available, as well as J2EE (Java 2 Enterprise 
Edition) compliance. 

J2EE represents an emerging suite of standard requirements placed on Java 
application servers like WebSphere. The Java Virtual Machine (JVM) 
supports the emerging Java Debug, Performance Profiling, and Wire 
protocols that enable third-party tools to work with the iSeries JVM, 
along with iSeries specific instrumentation for memory leak detection and 
enhanced debug. With this release, the suite of XML enablers can stay in 
step with the latest XML standards. The support for XML schemas is a key 
XML enabler extensions provided in this release. 

In V5R2, the iSeries supports the industry-standard JavaMail program 
interface used by applications to access or send e-mail using POP, IMAP, 
or SMTP protocols. 

IBM Toolbox for Java

New with V5R2 
New packages 
IBM Toolbox for Java 2 Micro Edition is a new package for IBM Toolbox for 
Java. The new com.ibm.as400.micro package provides a set of classes that 
enable you to write Java programs that run on wireless devices such as 
personal digital assistants and cellular phones. 
The Micro Edition package is available as part of JTOpen or from iSeries 
Access for Wireless (5722-XP1). 
For more information, see: 
http://www-1.ibm.com/servers/eserver/iseries/toolbox 
The iSeries System Debugger provides your workstation with a new graphical 
debugging environment for your ILE, Java, C and C++ programs on an iSeries 
server. 

New classes 
In V5R2, IBM Toolbox for Java also features many new classes in existing 
packages. 
The new classes enable you to: 
Use the ClusteredHashTable classes to share and replicate nonpersistent 
data among nodes in a cluster. 
Use the CommandPrompter class to prompt for parameters on a given command.

IBM Developer Kit for Java 

New with V5R2 
The changes to the IBM Developer Kit for Java in V5R2 include: 
Customizing: There are new system properties, including properties for 
Cache class loaders. 
Database access: 
?    The JDBC section has had extensive revision. The Developer Kit for 
Java JDBC driver, also known as the ?native? driver, provides programmatic 
access to iSeries database files. Using the JDBC API, applications written 
in the Java language can access JDBC database functions with embedded 
Structured Query Language (SQL), run SQL statements, retrieve results, and 
propagate changes back to the database. The JDBC API can also be used to 
interact with multiple data sources in a distributed, heterogeneous 
environment. 
?    Java stored procedures and Java user-defined scalar functions 
sections have been added. 

Run on a host without a GUI: If you want to run your Java application on a 
host that does not have a GUI, such as an iSeries server, you can use the 
Remote Abstract Window Toolkit (AWT), the Class Broker for Java (CBJ), or 
the Native Abstract Windowing Toolkit (NAWT). 

Commands and tools: 
?    The Analyze Java Virtual Machine (ANZJVM) command has been added to 
the CL commands section. 
?    The Java IDL-to-Java compiler (idlj) tool has been added. The idlj 
tool generates Java bindings from a given Interface Definition Language 
(IDL) 

WebSphere Development Studio

New with V5R2 
WebSphere Development Studio for iSeries V5R2 introduces the Eclipse-based 
IDE and WebSphere Studio Workbench, for integrating both IBM and non-IBM 
development tools. 

WebSphere Development Studio Client for iSeries, V5.0 integrates the key 
iSeries development tools to IBM?s Eclipse-based IDE, WebSphere Studio 
Workbench. This new IDE provides the infrastructure to integrate both IBM 
and non-IBM development tools and facilitate near seamless interoperation. 
The introduction of WebSphere Studio Workbench and the WebSphere Studio 
family of products is a significant advancement in application 
development.

the JMS provider of choice. 
New features that enhance system scalability and reliability. 
Simplified development of API exits to allow monitoring of local standards 
to be implemented. 

iSeries Access for Windows 

New with V5R2 
iSeries Access for Windows at V5R2 is enhanced in the following areas: 

Database Access 
?    ODBC and OLE DB now support ROWID, 64K SQL statements, and additional 
descriptor information. 
?    OLE DB can now support updated cursors for the SQL dialect. 
?    OLE DB is thread safe. 
?    Data transfer can support uploading more than 256 columns of data to 
a database file. 
?    Data transfer now supports Lotus 123 Version 9 file format. 
?    Data can be accessed from multiple independent auxiliary storage 
pools (IASPs). 

Security 
?    iSeries Access for Windows can now use a Kerberos server for 
authentication to an iSeries. Kerberos tickets are sent to the iSeries in 
place of a user ID and password, so users do not get a security prompt if 
they choose this option. 
?    Users of 56-bit encryption can use 128-bit encryption. 5250 emulation 

?    Version 5.5 of the Personal Communications 5250 emulator is now 
included. 
?    Bypass signon can now be used in conjunction with Kerberos tickets to 
avoid a signon screen.
