    <p><code>ORACLE_HOME</code> isn't set in the <code>su</code> environment. The full path to the <code>lsnrctl</code> binary is being provided because <code>$ORACLE_HOME</code> is being expanded before <code>su</code> is called, so you're really doing:</p> <pre><code>su oracle -c "/u01/app/oracle/product/12.1.0/dbhome_1/bin/lsnrctl start CAPEX" &amp; </code></pre> <p>When you run it manually <code>ORACLE_HOME</code> is set, so it works. When run through <code>su</code> it isn't, but it still finds the binary since it has the full path. <code>dbstart</code> works because it resets <code>ORACLE_HOME</code> from the <code>oratab</code> entries as it processes them. The 'no message file' error is usually an indicator that <code>ORACLE_HOME</code> isn't set, and the permission error the code refers suggests it's looking for the <code>listener.ora</code> in the wrong place, presumably under the root directory.</p> <p>You can demonstrate this by having the script try to display the value:</p> <pre><code>su $ORACLE_OWNER -c "ORACLE_HOME is: \$ORACLE_HOME`" </code></pre> <p>You could set the <code>ORACLE_HOME</code> in the command you're running through <code>su</code>, as:</p> <pre><code>su $ORACLE_OWNER -c "ORACLE_HOME=$ORACLE_HOME;$ORACLE_HOME/bin/lsnrctl start CAPEX" &amp; </code></pre> <p>But it's simpler to <code>export</code> the variables in your script, which will make them visible to <code>su</code>:</p> <pre><code>export ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1 export ORACLE_OWNER=oracle </code></pre> <p>or</p> <pre><code>ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1 ORACLE_OWNER=oracle export ORACLE_HOME ORACLE_OWNER </code></pre> <p>... depending on your shell.</p>

    1. COThanks for your answer. I modified the bash script according to your answer. Now I get no error message at startup but neither the listeners are started nor the database.

    2. CODo you get the messages you're echoing, and any banners etc. from the commands? Can you add more debugs to pinpoint when it's failing? Also you said it's a bash script - you haven't shown it, do you have `#!/bin/bash` at the top? Wondering if that export form is confusing root's default shell during boot. What happens if you run the script manually as root?

    3. COyou should check the alert.log and listener.log files.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
