admin port 4848 already used when starting Glassfish

"There is a process already using the admin port 4848 -- it probably is
another instance of a GlassFish server.
Command start-domain failed."


This problem may happen when you set a static IP address.
You need to make sure hostname should not leave blank but fill with the current hostname of your server, when configuring static IP address in network settings.

Alternative way to solve this is:
type: vi /etc/hosts
find, <your-static-ip>, and put <your-host-name> <your-host-name> after the static IP address.
then save the file, and try to start GlassFish again.

Set MySQL user password (Suse Linux Enterprise Server 11 terminal cannot type '(' & ')'. )

I had experience an irritating problem where Suse Linux Enterprise Server 11 terminal cant type '(' and ')' parenthesis.
If someone who know what is the cause of this problem, please comment and share with me. Thank you in advance!

So, I find another solution to solve the above problem.
Using MySQL Workbench, connecting to the server which installed mysql.

Tips (If your workbench cant connect to the server):
It is probably cause by the default privileges set in mysql.
you need to edit /etc/my.cnf
add bind-address=0.0.0.0
to allow all remote client to gain access to mysql.

Then, you can now connect to MySQL Workbench with the IP address of the MySQL server.
After connected,
Go to, edit->preferences->SQL editor (tab)->untick 'safe updates'
and reconnect using Workbench.

Finally, execute following query to change password of new installed MySQL (where parenthesis is needed!):
UPDATE mysql.user SET Password=PASSWORD('your-password') WHERE User='root';
FLUSH PRIVILEGES;

Problem Solved.
