I like to combine all Oracle Database 12c Tools: SQL*Plus, SQL Developer, and Oracle Enterprise manager Database Express 12 – EM12c. While I am working on a project, this allows me to switch fast from one tool to the other especially when I need to run any DDL statements, then go back to SQL Developer and create and test some PL/SQL code. Usually, EM12c is extremely fast for the tablespace creation or its management, especially when the new project starts.
task#9 In this task I will demonstrate the fastest way to create a tablespace when you needed it the most.
step# Connect to the pluggable database PDBORCL through EM12c using address “localhost:5502/em”. Ports 5500 and 5502 are by default reserved and assigned to the CDB$ROOT and PDBORCL databases accordingly on my Oracle Database 12c.
step#2 Open the Tablespace control window.
At the moment, we have 6 tablespaces: SYSTEM, SYSAUX, USERS, TEMP, EXAMPLE, and COMPANYAB.
step#3 Click on the Action Button and choose the Create option.
There are other options too, we can Drop any of the existing tablespaces, change the Status of the tablespace, Add a new datafile to the existing tablespace, and set a tablespace as Default one.
step#4 In the open Create tablespace window, enter the name of the new tablespace, in this case “COMPANYCD”, then click “>” button and follow the procedure.
step#5 See what SQL “CREATE TABLESPACE” statement will be executed, and make sure that all parameters are correct, such as the name of the datafile, size, logging, and compression. And if it is all as it should be, press OK button to execute that DDL statement.
step#6 The new tablespace has been created successfully.
step#7 Finally, The list of tablespaces has a new member, the tablespace “COMPANYCD”, and we are ready to start a new app.
step#8 Check with SQL*Plus that the tablespace datafile “COMPANYCD.DBF” is in the right directory on your computer

The Oracle Corporation recommends that the separate tablespaces should be created for any customer new applications in order to guarantee isolation, security, and easy management of the application and its tablespaces.
In this task I have shown how fast and easy is to create a tablespace on the fly using EM12c when you are desperate to start a new project.
