Operating System/400, 5769-SS1
• Integrated Netfinity Server hardware: The new Integrated Netfinity Server for AS/400
includes an Intel 700 MHz Pentium III processor and support for up to 4 GB of
memory. The faster processor and increased memory capacity provides increased
performance and capacity for Windows applications. This version of the Integrate
Netfinity Server is supported on the AS/400e 8xx, 270, SB2, and SB3 servers.
DB2 UDB for AS/400
DB2 UDB for AS/400 adds Java to the list of languages that stored procedures can be written
in. Stored procedures are an efficient method of performing SQL processing across a
network since one procedure can run multiple statements and logic to control statement flow
with minimal network traffic. Stored procedures written in Java are methods in Java classes.
Once a stored procedure is created and registered, and the Java classes are placed in the
correct file location, they can be called from any language that can execute SQL statements.
This includes running from remote systems with ODBC or DRDA. DB2 UDB for AS/400
performs the necessary setup to enable a Java virtual machine to run the methods and
performs the conversion between SQL types and Java objects.
DB2 CLI, the call level interface for running SQL statements from ILE programming
languages, is more compatible in V4R5 with the ODBC standard. This makes porting
applications written to the popular ODBC standard much easier.
DB2 UDB for AS/400 adds support for big integers. A big integer is a binary number
composed of eight bytes (64 bits) with a precision of 19 digits.
SQL procedure and SQL function language enhancements at V4R5 include: SIGNAL,
RESIGNAL, and GOTO. The scalar functions that are added include:
• Allow word sounds to be compared (SOUNDEX and DIFFERENCE)
• Return random numbers (RAND)
• Perform geometric operations (RADIANS and ATAN2)
• Perform numeric rounding and truncation (ROUND, TRUNCATE, and CEILING)
• Evaluate the sign of numeric data (SIGN)
• The number of rows in a single non-distributed table is doubled to more than four billion.
The number of tables in an SQL statement is increased to 256.
Asynchronous I/O Completion Port Support and APIs for OS/400 Sockets at V4R5
V4R5 includes support for Asynchronous I/O Completion Ports (Async IOCP) as part of the
OS/400 sockets APIs implementation. These new socket APIs provide scalable, efficient, and
powerful method for multi-threaded Internet and e-business server applications to process
client data.
Internet, e-business, and other network server applications utilizing Async IOCP design
models and APIs should allow a much smaller pool of threads to process work from clients
