– Creating certificates using a Public Key Infrastructure for X.509 (PKIX) Certificate
Authority (CA)
– Adding and removing applications that use certificates
• Enhanced Password Protection: Support is added to the system to enable case
sensitive user profile passwords up to 128 characters in length with a larger character
set. This support provides greater security for the user profile password (new system
value: QPWDLVL). Before taking advantage of the longer passwords, we recommend
that you review the security reference manual for a complete description of the
potential compatibility arrangements when using the new support.
DB2 Universal
Integrated DB2 Universal Database for iSeries
DB2 Universal Database (UDB) for iSeries is fully integrated into the OS/400 operating
system software. It is not a separate product. DB2 UDB for iSeries offers state-of-the-art
database functions and open- systems, standards based technology, while providing the
maturity, stability, and ease of use that has become the trademark of the iSeries server.
The iSeries server can be used for both traditional, transaction processing and decision
support and data warehousing applications. Advanced parallel processing and advanced
query optimization techniques support queries of large decision support databases. An
integrated iSeries database offers many advantages. As an integrated part of OS/400, DB2
UDB for iSeries is installed with the system providing automatic bring up and recovery
functions when the system is IPLed. Integration also allows the database commands and
display interfaces to have a look and feel that is consistent with the rest of the system. For
example, database objects are automatically included as part of the system-wide cross
reference facilities and the basic system administration commands for save, restore, security,
and object management can be used to administer the database. This allows the database to
exploit new system functions and hardware for improved availability, recovery, security,
concurrency, and performance as they are introduced.
Conformance to industry database standards, advanced functions, and distributed data
capabilities with supporting performance allows DB2 UDB for iSeries to operate equally well
with centralized database applications, or as the database server in complex heterogeneous
client/server networks. DB2 UDB for iSeries unique combination of function and reliability
make the iSeries the ideal database server for many customers' needs.
DB2 UDB for iSeries Open Standards-Based Interoperability
Support for client/server environments has been greatly enhanced by incorporating popular
database standards and transmission protocols. DB2 UDB for iSeries provides support for:
