VMNet1 not up after Hibernate

The vmnet configuration of VMWare Server in (Ubuntu)Linux is quite rudimentary. It is done using a script whereas in Windows you'll lucky to have a nice configuration screen.
I regularly just wrap-up my wrap-box (in Dutch I tend to call my notebook 'klapdoos') after work. I configured it such that it will hibernate my Linux.
But after resume I experienced that the VMNetwork is not up. That is quite inconvenient, because I would have to restart my machine and then suspend or start my VMware images. I need the VMNet1 (host only) often because I let several VM's work together and I connect to the machines using jDeveloper, sqlDeveloper, etc. from my host. Or Pl/Sql Developer on another VM.

Luckily I found on an Ubuntu forum a simple command to startup the vmnet's again:
ifconfig vmnet1 up

So I created a simple script VMNetup:
ifconfig vmnet1 up
ifconfig vmnet8 up

I put the script in /usr/lib/vmware/lib and added the command
"sudo /usr/lib/vmware/lib/vmnetup" to my System Tools menu. I set the type on 'Application in Terminal' since I have to give in a password for the sudo command.

Now with a simple menu click and a password my problem is solved.

Hey Anonymous,

If you logon on the database on the console of the os, then you might bypass the listener.

You could check the listener.ora and tnsnames.ora in /network/admin. Make sure the entries there refer to a hostname that point to a correct ip-address.

Then with "lsnrctl status" you can check if the listener "knows" the database.

And finally start the listener before the database.
