PM40861: IT WILL TAKE A VERY LONG TIME TO STOP A SERVER ON HP-UX WHEN THE DNS SERVER IS NOT AVAILABLE.

APAR status

Closed as program error.

Error description

Product Version: WebSphere Application Server Base edition
6.1.0.17

OS Version:      HP-UX version B.11.23

Java Version:    1.5.0.12-_21_mar_2008

Problem Description:
It would take a very long time to stopa server when the DNS
server was not available.

This issue is relative to the following function:
host = InetAddress.getLocalHost().getHostName();

When the DNS server is not available, this function will be
continuously looking up for a response.

Usually we can add a JVM parameter
"-Dcom.ibm.cacheLocalHost=true" as a workaround, but it is not
applicalble to HP-UX.

* RECOMMENDATION:                                              *
****************************************************************
It takes a long time for an application server to stop when a
DNS server is not available. This is due to the multiple JAVA
calls to getHostName() which may be long in the case where the
DNS server is not available.

Problem conclusion

Code has been changed to cache the hostname at start up. This
should mean that the delay occurs only once the first time the
unique value is generated for the hostname. From then on, the
local copy of hostname can be used. This will avoid the Java
calls to getHostName() which may take a long time if the DNS
server is not available.

The fix for this APAR is currently targeted for inclusion in
fixpacks 6.1.0.41 and 7.0.0.19. Please refer to the
