Setting ejb-timer-service property causes set command to fail (6193449)

Description

After setting the ejb-timer-service property minimum-delivery-interval to 9000, an attempt to set the ejb-timer-service property redelivery-interval-in-mills to 7000 causes the set command to fail with the following error:

[echo] Doing admin task set
[exec] [Attribute(id=redelivery-interval-internal-in-millis) : 
Redelivery-Interval (7,000) 
should be greater than or equal to Minimum-delivery-interval-
in-millis (9,000)]
[exec] CLI137 Command set failed.

• minimum-delivery-interval is the minimal interval duration between deliveries of the same periodic timer.

• redelivery-interval-in-mills is the time the timer service will wait after a failed ejbTimeout before attempting redelivery.

The problem is that the logic that relates the redelivery interval property to the minimum delivery property is incorrect and prevents you from using the GUI or the CLI to set any value where the minimum delivery interval is greater than redelivery interval.

The minimum-delivery-interval-in-millis must always be set equal to or higher than ejb-timer-service property redelivery-interval-in-millis. The problem is that there is an erroneous validation check in the aerver to verify that the value for redelivery-interval-in-millis is greater than the value for minimum-delivery-interval-in-millis.

Solution

Use the default values for these properties, as follows:

minimum-delivery-interval(default)=7000
redelivery-interval-in-millis(default)=5000

Values other than these defaults will generate an error.

Error thrown when list JMS physical destinations within non-DAS config (6532532)

Description

If you are trying to view the JMS Physical Destinations using the default-config, you will see an error message.

Solution

This is expected behavior. In Enterprise Server 2.1, default-config is a template of configuration information and hence JMS operations (such as list and create) cannot be executed for the default-config. These JMS operations can, however, be executed for the configurations of your cluster or standalone instances.

Win2003 only: Non-paged pool leak memory, breaking tcp stack and richaccess test (6575349)

Description

(Windows 2003 only) There are memory leaks on Windows 2003 systems when performing rich access functions. The problem occurs because the Win32 nonpaged pool keeps growing, eventually bringing down the entire TCP/IP stack. Once the failure happens, the TCP/IP stack is left in an recoverable state, and the only way restore it is by rebooting the Windows 2003 system.

Workaround

There are two workarounds to this issue:

• Use Grizzly blocking mode by configuring the domain.xml http-listener attribute, blocking-enabled="true" or add the following http-listener property:

  <property name="blocking" value="true"/>

• Use Windows Vista or Windows XP.
