Release Notes for Cisco Application-Oriented Networking Version 2.1.1
June 7, 2006
Cisco Application-Oriented Networking (AON) is the first in a new line of Cisco products that embed intelligence into the network to meet the needs of application deployment. AON enables you to:
•Integrate dissimilar applications by routing information to the appropriate destination, in the format required at the destination.
•Enforce policies for information access and exchange.
•Optimize bandwidth and reduce processing overhead for application traffic.
•Increase management of information flow, including monitoring for business and infrastructure.
•Enhance business continuity by transparently backing up or rerouting critical business data.
Working at the message rather than packet level, AON provides this support by understanding more about the content and context of information flow.
These release notes cover Cisco Application-Oriented Networking Version 2.1.1 and include the following topics:
AON Application Requirements
Table 1 lists the minimum requirements for installing AON applications.
AON Node Supported Hardware
Table 2 lists the hardware platforms that are supported by AON version 2.1.1.
AON Node Supported Software
Table 3 lists the software levels for the Cisco platforms that support AON.
•The AON Management Console (AMC) supports only Microsoft Internet Explorer 6. AMC pages may not render properly in other Web browsers.
•AON is implemented in Java where memory is automatically managed by the Java runtime system. This means that there might be moments in the system where the garbage collection (automatic memory management) is still working at freeing up memory. The graceful handling mechanism checks the free memory to determine if a message should be let into the system. So under high loads it is possible that AON will reject messages because the garbage collection is taking time to free up memory.
•The following issues may affect AON Development Studio installation, however, the root causes are beyond the control of Cisco:
–Using the ALT key during ADS installation can cause some InstallShield screens to become corrupted. Despite this display problem, the ADS installer continues to function. If the display gets corrupted, minimize the ADS installer and then maximize it again. The display should return to normal. This is a known InstallShield issue when using JVMs with version 1.4.2.x.
–In rare situations when initially launching ADS on Windows 2000, an error message may be returned indicating the database is busy or unavailable. The error can occur even though the database is listed as started in the list of Windows Services. This occurs when a database port is chosen in the ADS installer that also appears in the output of the netstat -a command in a loopback situation. The port is shown pointing to another server port which in turn points back to it. This behavior has only been seen with one port, though not always the same port on the system. Reboot the PC to correct this problem.
Table 4 lists the caveats that have been resolved in this AON release.
Table 5 lists the caveats for this AON release. These caveats are in addition to the open caveats listed in the Release Notes for Cisco Application-Oriented Networking Version 2.1
Table 5 Open Caveats for Cisco Application-Oriented Networking Version 2.1.1
Defect ID Description
When the flow has multiple SetDestination Bladelets (with XPath rules) or if there are Find Bladelets ahead of SetDestination Bladelet (with XPath Rules), SetDestination's XPath evaluation returns NULL for the first request message.
Send another message.
If there is an existing or new sequence in the schema, the message log writing and viewing in AMC fails.
For Oracle, do not change the schema after it is created using the scripts in appendix A. This information is found in "Create a Message Log Database" section of Chapter 4, Step 1, in the Cisco AON Installation and Administration Guide.
Note If changes are added, it may cause the message log feature to fail. For example, as reported in this defect, existing or new sequences to the schema can cause older version before 2.1.1 to fail.
Multiple modifications to JMS/SSL Property & Single deployment doesn't work correctly. The changes notification did not happen on the corresponding nodes. Only some of the modifications had done to the JMS/SSL property take effect and sometimes AON stops listening to the modified JMS queues.
Make a series of changes to a JMS property and do a single deployment from AMC to nodes. The changes notification did not happen on the corresponding nodes.
Either deploy one JMS property change at a time, or restart AON.
For detailed instructions on upgrading to Cisco Application-Oriented Networking Version 2.1.1, see the following document:
Cisco Application-Oriented Networking 2.1 and above releases are backward compatible.
Note You must install the latest Cisco AON Management Console (AMC) release and AON Developer Studio (ADS) software on your node. Both these software versions must match for the node to work.
Cisco Application-Oriented Networking Version 2.1.1 will work with any node with Cisco AON Version 2.1.
The AON documentation set includes the following guides:
• AON Development Studio User Guide—covers the AON Development Studio, Bladelets, and PEP creation.
• AON Programming Guide—covers the development of custom Bladelets, custom adapters, and other features related to extending AON functionality.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
