File Path and Directory Changes in Read-Only Oracle Homes

Learn from these examples the differences between hierarchical file mappings in a read-only Oracle home compared to a read/write Oracle home.

This example shows an Optimal Flexible Architecture-compliant Oracle Database installation, for the user oracle, with the ORACLE_HOME, ORACLE_BASE, ORACLE_BASE_HOME, and ORACLE_BASE_CONFIG logical locations. The database files are mounted on /u01 and the HOME_NAME is OraDB23Home1.

This example also shows the changes in the Oracle Database software defined paths of configuration files, log files, and other directories in a read-only Oracle home when compared to a read/write Oracle home.

• To print the ORACLE_BASE_HOME path, run:

  $ setenv ORACLE_HOME /u01/app/oracle/product/23.0.0/dbhome_1
  $ cd $ORACLE_HOME/bin
  $ ./orabasehome

• To print the ORACLE_BASE_CONFIG path, run:

  $ setenv ORACLE_HOME /u01/app/oracle/product/23.0.0/dbhome_1
  $ cd $ORACLE_HOME/bin
  $ ./orabaseconfig
