All rights reserved. # ################################### # # usage: dbstart $ORACLE_HOME # # This script is used to start ORACLE from /etc/rc(.local). # It should ONLY be executed as part of the system boot procedure. # # This script will start all databases listed in the oratab file # whose third field is a "Y". If the third field is set to "Y" and # there is no ORACLE_SID for an entry (the first field is a *), # then this script will ignore that entry. # # This script requires that ASM ORACLE_SID's start with a +, and # that non-ASM instance ORACLE_SID's do not start with a +. # # If ASM instances are to be started with this script, it cannot # be used inside an rc*.d directory, and should be invoked from # rc.local only. Otherwise, the CSS service may not be available # yet, and this script will block init from completing the boot # cycle. # # If you want dbstart to auto-start a single-instance database that uses # an ASM server that is auto-started by CRS (this is the default behavior # for an ASM cluster), you must change the database's ORATAB entry to use # a third field of "W" and the ASM's ORATAB entry to use a third field of "N". # These values specify that dbstart auto-starts the database only after # the ASM instance is up and running. # # Note: # Use ORACLE_TRACE=T for tracing this script. # # The progress log for each instance bringup plus Error and Warning message[s] # are logged in file $ORACLE_HOME/startup.log. The error messages related to # instance bringup are also logged to syslog (system log module). # The Listener log is located at $ORACLE_HOME_LISTNER/listener.log # # On all UNIX platforms except SOLARIS # ORATAB=/etc/oratab # # To configure, update ORATAB with Instances that need to be started up # Entries are of the form: # $ORACLE_SID:$ORACLE_HOME:<N|Y|W>: # An example entry: # main:/usr/lib/oracle/emagent_10g:Y # # Overall algorithm: # 1) Bring up all ASM instances with 'Y' entry in status field in oratab entry # 2) Bring up all Database instances with 'Y' entry in status field in # oratab entry # 3) If there are Database instances with 'W' entry in status field # then # iterate over all ASM instances (irrespective of 'Y' or 'N') AND # wait for all of them to be started # fi # 4) Bring up all Database instances with 'W' entry in status field in # oratab entry # ##################################### LOGMSG="logger -puser.alert -s " trap 'exit' 1 2 3 # for script tracing case $ORACLE_TRACE in T) set -x ;; esac # Set path if path not set (if called from /etc/rc) SAVE_PATH=/bin:/usr/bin:/etc:${PATH} ; export PATH SAVE_LLP=$LD_LIBRARY_PATH # First argument is used to bring up Oracle Net Listener ORACLE_HOME_LISTNER=$1 if [ ! $ORACLE_HOME_LISTNER ] ; then echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener" echo "Usage: $0 ORACLE_HOME" else LOG=$ORACLE_HOME_LISTNER/listener.log # Set the ORACLE_HOME for the Oracle Net Listener, it gets reset to # a different ORACLE_HOME for each entry in the oratab. export ORACLE_HOME=$ORACLE_HOME_LISTNER # Start Oracle Net Listener if [ -x $ORACLE_HOME_LISTNER/bin/tnslsnr ] ; then echo "$0: Starting Oracle Net Listener" >> $LOG 2>&1 $ORACLE_HOME_LISTNER/bin/lsnrctl start >> $LOG 2>&1 & VER10LIST=`$ORACLE_HOME_LISTNER/bin/lsnrctl version | grep "LSNRCTL for " | cut -d' ' -f5 | cut -d'.' -f1` export VER10LIST else echo "Failed to auto-start Oracle Net Listener using $ORACLE_HOME_LISTNER/bin/tnslsnr" fi fi # Set this in accordance with the platform ORATAB=/etc/oratab if [ ! $ORATAB ] ; then echo "$ORATAB not found" exit 1; fi # Checks Version Mismatch between Listener and Database Instance. # A version 10 listener is required for an Oracle Database 10g database. # Previous versions of the listener are not supported for use with an Oracle # Database 10g database.
