Workshop Scenario 5
This workshop scenario pertains to database availability. To introduce the problem, first logout
of Enterprise Manager. Then, change directory to $HOME/workshops and run the script
wlab_05.sql as the SYSTEM user as shown below:
SQL> @wlab_05.sql
Start your investigation by going to the Enterprise Manager console and viewing the Database
page. Record the results of your investigation under “Observations”. Once you have determined
the problem, formulate a plan to correct the problem. It is possible that there may be more than
one viable solution. Record all possible methods that will address the problem under
“Methodology”.
It is your job to pick the best solution to solve your database problem. After applying your
solution, verify that the problem has been corrected. Record your results under “Results”.
