3. Exporting

Create a full export of the source database. Includes schema, data, & routines.

./cron.driver.sh -c 'configs/my_config.cfg' -a 'export' -p 'myPassword'

• Creates a new directory in [my_config.cfg->DUMP_FOLDER_NAME]
• Does a complete export of the database into the new directory
• Compresses & removes the new directory, if 'zip' is available
• Appends a records to the log file (export.log)

4.a. Importing (Single target database)

Imports the latest dump file into the target database after clearing it.

./cron.driver.sh -c 'configs/my_config.cfg' -a 'import' -p 'myPassword'

• Checks the latest dump file in [my_config.cfg->DUMP_FOLDER_NAME]
• Clears the database defined in the config file
• Imports the latest dump file

4.b. Importing (Alternating target databases)

Imports the latest dump file into the (inactive) target database after clearing it. Ensures that there will always be a live version of the target database available. Use case: QA environments.

./cron.driver.sh -c 'configs/my_config.cfg' -a 'import' -p 'myPassword'

• Checks the latest dump file in [my_config.cfg->DUMP_FOLDER_NAME]
• Selects the appropriate target database. -- Even Week = Database 1 -- Odd Week = Database 2
• Clears the database defined in the config file
• Imports the latest dump file
