How do you use "startup" Command to Start Default Instance?
Submitted by: AdministratorIf you logged in to the server as a SYSDBA, you start the default instance with the "startup" command. Here is how to start the default instance in SQL*Plus in SYSDBA mode:
>.insqlplus
Enter user-name: SYSTEM/globalguideline AS SYSDBA
Connected to an idle instance
SQL> show instance
instance "local"
SQL> startup
ORA-00821: Specified value of sga_target 16M is too small,
needs to be at least 20M
Now the server is telling you more details about the memory problem on your default instance: your SGA setting of 16MB is too small. It must be increased to at least 20MB.
