The transaction log for database 'SharePoint_Config' is full

Hi all ,

I am very new to sharepoint. when i tried to remove a wsp file from central administration i got the message like

The transaction log for database 'SharePoint_Config' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases.

Can anybody help me to solve this please. I saw one solution in net like this but i don't know how to do this. Can anybody help me how to do these steps please.

1.       Take the configuration database offline and detach it

2.       Copy the current MDF to a new location (to be used as a way of recovering the database if needed)

3.       Put the database back on-line, reattach it and then put it within simple mode (from full), with an aim of this stopping the database from increasing in size

4.       Shrink the database and recover log space

5.       Should the shrinking fail, we'd look at detaching the database, making a sideways copy of the log file to another database

6.       We would then reattach the database, which should generate a new log file

Thank you
