How to change the protection mode from "maximum performance" to "maximum availability" in a 10g Data Guard environment?
Maximum Protection—This mode offers the highest level of data protection. Data is synchronously transmitted to the standby database from the primary database and transactions are not committed on the primary database unless the redo data is available on at least one standby database configured in this mode. If the last standby database configured in this mode becomes unavailable, processing stops on the primary database. This mode ensures no-data-loss.
Maximum Availability—This mode is similar to the maximum protection mode, including zero data loss. However, if a standby database becomes unavailable (for example, because of network connectivity problems), processing continues on the primary database. When the fault is corrected, the standby database is automatically resynchronized with the primary database.
Maximum Performance—This mode offers slightly less data protection on the primary database, but higher performance than maximum availability mode. In this mode, as the primary database processes transactions, redo data is asynchronously shipped to the standby database. The commit operation of the primary database does not wait for the standby database to acknowledge receipt of redo data before completing write operations on the primary database. If any standby destination becomes unavailable, processing continues on the primary database and there is little effect on primary database performance.

11g R2 (11.2.0.2) -- Script to Auto Start/Shutdown databases during reboots.
Step 1:
Login as root and create a file called /etc/init.d/oracle. Add the following lines in the script.
#!/bin/bash
#######################################################################
#
# Run-level Startup script for the Oracle Instance and Listener
#
# chkconfig: 345 98 34
# description: Startup/Shutdown script for 11g Oracle instances
#
#######################################################################
#######################################################################
#
# Note:
# cp $ORACLE_HOME/bin/dbstart $ORACLE_HOME/bin/dbstart.orig
# Make the following changes in $ORACLE_HOME/bin/dbstart
#
# Line#80 has the following:
# ORACLE_HOME_LISTNER=$1
#
# Replace it with the following two lines:
# export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
# ORACLE_HOME_LISTNER=$ORACLE_HOME
#
# cp $ORACLE_HOME/bin/dbshut $ORACLE_HOME/bin/dbshut.orig
# Make the following changes in $ORACLE_HOME/bin/dbshut
#
# Line#50 has the following:
# ORACLE_HOME_LISTNER=$1
#
# Replace it with the following two lines:
# export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
# ORACLE_HOME_LISTNER=$ORACLE_HOME
#
# save the file and proceed with the steps below

clear
###################### END of SCRIPT ##############################
Step-2:
Change the permission of the script
chmod 750 /etc/init.d/oracle
Step-3:
Execute the following so that runlevel 3,4 & 5 will execute the script during system reboots.
chkconfig --level 345 oracle on
Step-4
Execute the script and verify everything is working as expected. Alternatively, you can download the script directory from here.
Additionally you can turn on and turn on with the following.
[root@bl-mm-db-dev ~]# /sbin/chkconfig oracle off
[root@bl-mm-db-dev ~]# /sbin/chkconfig --levels 345 oracle on
That's it. We are done.
