As i noticed today „orabase“ command does not print the ORACLE_BASE path on standard out in my test environment.
Whats wrong? Is it a bug or a feature ?
What i expected …
- Executing $ORACLE_HOME/bin/orabase show the oracle base directory without defined environment variable ORACLE_BASE.
- This information is stored in $ORACLE_HOME/install/orabasetab during the installation process.
- The orabasetab file is used to track Oracle Home associated with Oracle Base
But i got this:
|
1 2 3 |
cd $ORACLE_HOME/bin ./orabase <no value> <-- $ORACLE_BASE path should be printed here |
My analysis steps …
So i had a look into my orabasetab:
|
1 2 |
vi /app/oracle/product/12.1.0/db12102_160119/install/orabasetab /app/oracle/product/12.1.0/db12102_160119/:/app/oracle:db12102_160119:N: |
MOS Note 2225573.1 show correct orabasetab definition:
|
1 2 |
$ORACLE_HOME/install/orabasetab correct format is: Actual Oracle Home:Actual Oracle Base:Oracle Home Name:< Y or N > |
My results …
- I made a typo during installation process or any other one
- The Oracle Home and Base entries was separated by „/:“ in my orabasetab but should be separated by „:“ only.
- This corrupted the orabasetab!
- So i fixed this and orabase printed the right base path again.
