Determining if an Oracle Home is Read-Only

Run the orabasehome command to determine if your Oracle home is a read/write or read-only Oracle home.

If the output of the orabasehome command is the same as $ORACLE_HOME, then your Oracle home is in read/write mode. If the output displays the path ORACLE_BASE/homes/HOME_NAME, then your Oracle home is in read-only mode.

Set the ORACLE_HOME environment variable:

Bourne, Bash or Korn shell:

$ ORACLE_HOME=/u01/app/oracle/product/19.0.0/dbhome_1
$ export ORACLE_HOME

C shell:

% setenv ORACLE_HOME /u01/app/oracle/product/19.0.0/dbhome_1

Go to the bin directory and run the orabasehome command:
```
$ cd $ORACLE_HOME/bin
$ ./orabasehome
/u01/app/oracle/homes/OraDB19Home1
```
In this example, the Oracle home is in read-only mode.
