Network Address Cache In Java Caps Domain (Doc ID 1460589.1)

Last updated on NOVEMBER 03, 2016

Applies to:

Oracle Java CAPS - Version 5.1.3 to 5.1.3 [Release 5.1]
Information in this document applies to any platform.

Symptoms

 When a domain connects with an external system that changes its server IP address, it becomes imperative to stop/restart the domain to make it aware of the new IP address. This is demanding on a Production system.

On the Solaris operating system, one could see that the new address is properly returned via a DNS lookup.  However, it appears that the JavaCaps domain is caching DNS information as it is still using/resolving the old IP address.
From a network traffic analysis, one could see that the URL, although the DNS was changed, still is resolving the old IP address.

After the domain restarts, the new IP is succesfully resolved.
