Time for action – creating objects on the logical standby database

Now let's try to create some objects on the logical standby database. First we will create a test table with the HR user. The Database Guard mode is ALL, which is the default.

1. Connect the logical standby database with SYS user and execute the following query:

   SQL> SELECT GUARD_STATUS FROM V$DATABASE;
   
   GUARD_S
   -------
   ALL
   
   SQL> CONN SCOTT/TIGER
   Connected.
   SQL> CREATE TABLE TEST (A NUMBER);
   create table test (a number)
   *
   ERROR at line 1:
   ORA-01031: insufficient privileges

   The error message specifies a privilege problem but this is not due to the lack of create table privilege for the HR user. We receive this error because the Database Guard mode does not allow for creation of the table. Let's change it and try again.

2. Connect with the SYS user using the following query:

   SQL> ALTER DATABASE GUARD STANDBY;
   Database altered.
   
   SQL> CONN SCOTT/TIGER
   Connected.
   
   SQL> CREATE TABLE TEST (A NUMBER);
   Table created.
