Create the second oracle Database in Linux

In linux, only one Oracle database can be created. However, you can create different tablespaces for different users. The format is as follows:

Create tablespace vewertemp datafile '\ oracle \ oradata \ viewer \ dbvewertemp. dbf' size 50 M autoextend on next 128 k maxsize unlimited;
Create temporary tablespace viewertmp tempfile 'dbviewertmp. ora 'size 5 M autoextend on next 128 k maxsize unlimited;
