Oracle automatically activated under linux and stop

Jul 12 posted in Oracle (RSS), 113 views.

Oracle modify the system configuration file / etc / oratab
/ etc / oratab format: SID: ORACLE_HOME: AUTO
AUTO field is set to the Y (upper case), the only way, oracle and dbstart own dbshut be able to play a role. I am for:
$ ORACLE_SID: $ ORACLE_HOME: Y
ORACLE_SID and ORACLE_HOME here is under the oracle user environment variables, in different computers have different values. When you open the / etc / oratab time, changed a bit on the list.
Services in the preparation of the script / etc / rc.d / init.d directory oracle file created as a startup script, which reads as follows:
#! / bin / bash
# chkconfig: 2345 50 10
# description: Start and stop Oracle Database and monitoring procedures
# / Etc / rc.d / init.d / oracle
# Check how to implement the script file

In the oracle user, enter the contents of As, and then save out as a result of the startup script, the need for the implementation of authority; the implementation of the command chmod a + x oracle grant execute permissions oracle.
The establishment of service connection
ln-s / etc / rc.d / init.d / oracle / etc/rc.d/rc2.d/S50oracle
ln-s / etc / rc.d / init.d / oracle / etc/rc.d/rc3.d/S50oracle

ln-s / etc / rc.d / init.d / oracle / etc/rc.d/rc0.d/K10oracle
ln-s / etc / rc.d / init.d / oracle / etc/rc.d/rc6.d/K10oracle
chkconfig - add oracle (added to the system services)
chkconfig - levle 2345 oracle on (with the system to start)
Test
Run. / Oracle start (service oracle start) command to see if can start the database, if not, view the log, find out the reasons when I have encountered in the implementation of the following error message may
Can''t find init file for Database "linuxdb".
Database "linuxdb" NOT started.
By looking at $ (ORACLE_HOME) / bin / dbstart the script, based on erroneous information to find the statement, that the system lacked a
$ (ORACLE_HOME) / dbs / init $ (ORACLE_SID). Ora profile solution
sqlplus "/ as sysdba"
create pfile from spfile;
And then on the successful implementation.
Linux restart the host to see whether the database automatically activated.

Note: oracle scripts dbstart own Listeners contains scripts to start, so I think that should be above the startup script to remove the phrase listeners, otherwise they will be in error, but this error does not affect the start.
