What's new for V5R4

iSeries NetServer™ has the following performance and scalability enhancements and new functions for V5R4:

• Threading support: To increase performance, NetServer now supports the use of pools of threads to process client requests. The new QZLSFILET job handles threaded requests.
• Opportunistic locks: Clients have the option of caching application requests to reduce network traffic and server overhead.
• LAN Manager password hash: When enabled, it allows Windows clients to authenticate with the less secure (not case sensitive) LAN Manager password hash even if the more secure (case sensitive) NT password hash is also provided and does not match.
• Message authentication/signing support: For more secure communications between the client and server, NetServer now supports connection request signing. Signing requests provides improved protection from the following types of attacks: connection hijacking, downgrade attack, rogue server and spoofing by counterfeit servers, active message modification, and replay attacks. See Require clients to sign requests for more information.
• Windows-style messages: The server can be configured to alert users who are running Microsoft Messenger or similar service using the iSeries Navigator graphical user interface (GUI). See Use Windows-style messages with iSeries NetServer for more information.
