I'm running Parallels Desktop 6 For Mac on my host system, a MacBook Pro 2.2GHz i7, and installed Debian as my Guest OS. I'm attempting to install WebSphere Portal Server onto my Linux OS, which also installs DB2. The problem that I am having during the installation of WebSphere is that upon initialization of the database a connection to the database is required. While my Mac is registered with DNS and is accessible by name, my guest OS is not registered in DNS but I need to be able to connect to the database instance by server name. I tried to specify my Host machine name but I am unable to obtain a connection to DB2 this way. When I ask for the host name from the guest OS by executing uname -a, it returns Linux sfofcb-nxp6149a 2.6.32-5-686 #1 SMP Mon Jun 13 04:13:06 UTC 2011 i686 GNU/Linux So the host name is sfofcb-nxp6149a, but how do I access this server instance if it is not registered in DNS? Is there some configuration that I need to perform to be able to access DB2 by Host OS name? Thank you for the assistance.
