The following is a table comparison between InnoDB with MyISAM
|
|
My ISAM InnoDB Required full text Search Yes Require Transactions Yes frequent select queries Yes frequent insert,update,delete Yes Row Locking (multi processing on single table) Yes Relational base design Yes |
There is minor problem that MyISAM did not support Transactions and innoDB are more relialbe on atomicity. But you can solve that problem by your own programmming design, you can achieve that by random no method, you can achieve parallelism also
Here is a simple shell script to automatically Convert MySql Database from InnoDB to MyISAM.
|
|
#!/bin/bash MYSQLCMD=mysql for db in 'echo show databases | $MYSQLCMD | grep -v Database'; do for table in 'echo show tables | $MYSQLCMD $db | grep -v Tables_in_'; do TABLE_TYPE='echo show create table $table | $MYSQLCMD $db | sed -e's/.*ENGINE=([[:alnum:]]+)[[:space:]].*/1/'|grep -v 'Create Table'' if [ $TABLE_TYPE = "InnoDB" ] ; then mysqldump $db $table > $db.$table.sql echo "ALTER TABLE $table ENGINE = MyISAM" | $MYSQLCMD $db fi done done |

Use fetch option to get all available binary updates:
Install Update
Install the most recently fetched updates:
Rollback updates
Optional: You can uninstall most recently installed updates:
|
|
# freebsd-update rollback |

To upgrade Freebsd, we will be using freebsd-update, a great piece of software that fetches and installs binary updates to FreeBSD.
Step 1 : Fetch updates
|
|
# freebsd-update fetch # freebsd-update install |
If any updates where installed above – reboot your system before continuing.
Step 2 : Upgrade FreeBSD
|
|
# freebsd-update upgrade -r 9.1-RELEASE # freebsd-update install |
The system must now be rebooted with the newly installed kernel before the non-kernel components are updated.
Step 3: Install Update
After rebooting, freebsd-update(8) needs to be run again to install the new userland components:
# freebsd-update install
Step 4: Finally, reboot into 9.1-RELEASE
# reboot
