dbstart: line 275: ORACLE_HOME_LISTNER: command not found

Usage : we can use dbstart script file in $ORACLE_HOME/bin to start database & listener.

[oracle@Linux03 bin]$ ps -ef|grep pmon
oracle   20588 19211  0 10:56 pts/0    00:00:00 grep pmon

[oracle@Linux03 bin]$ dbstart
Processing Database instance "orcl": log file /u01/app/oracle/product/12.1.0.2/db_1/startup.log

[oracle@Linux03 bin]$ ps -ef|grep pmon
oracle   20693     1  0 10:57 ?        00:00:00 ora_pmon_orcl
oracle   21035 19211  0 10:57 pts/0    00:00:00 grep pmon

[oracle@Linux03 bin]$ 



Common error with dbstart script :


Error : /u01/app/oracle/product/12.1.0.2/db_1/bin/dbstart: line 275: ORACLE_HOME_LISTNER: command not found

[oracle@Linux03 bin]$ dbstart

/u01/app/oracle/product/12.1.0.2/db_1/bin/dbstart: line 275: ORACLE_HOME_LISTNER: command not found


Solution : Edit dbstart script and change (~ line 275)

 From : ORACLE_HOME_LISTNER=$1

 To   : ORACLE_HOME_LISTNER=$ORACLE_HOME

Note : 
One pre-req for this script to run is set 'Y' in /etc/oratab. This basically tell the script to start all database instance running of this home. while 'N' tells not to start db using dbshut script.

[oracle@Linux03 Desktop]$ grep 'orcl' /etc/oratab
orcl:/u01/app/oracle/product/12.1.0.2/db_1:Y
