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.

1. Set the ORACLE_HOME environment variable:

   Bourne, Bash or Korn shell:

   $ ORACLE_HOME=/u01/app/oracle/product/18.0.0/dbhome_1
   $ export ORACLE_HOME

   C shell:

   % setenv ORACLE_HOME /u01/app/oracle/product/18.0.0/dbhome_1

2. Go to the bin directory and run the orabasehome command:

   $ cd $ORACLE_HOME/bin
   $ ./orabasehome
   
   $ /u01/app/oracle/homes/OraDB18Home1

   In this example, the Oracle home is in read-only mode.
