Similarly as with each other information base, Amazon RDS MYSQL likewise needs DBA undertakings to adjust the data set and do occasional wellbeing checks and so on Yet, as the AWS stage doesn't permit the shell admittance to the DB, there are a predetermined number of DBA errands that can be proceeded when contrasted with the on-premise establishment of MySQL. The following is a rundown of normal DBA errands that can be acted in AWS RDS MySQL information base and their depictions.
Getting to Error Logs
The MySQL blunder log ( mysql-error.log) record can be seen by utilizing the Amazon RDS support or by recovering the log utilizing the Amazon RDS CLI. mysql-error.log is flushed at regular intervals, and its substance are annexed to mysql-mistake running.log. The mysql-blunder running.log document is then pivoted each hour and the hourly records produced during the most recent 24 hours are held.

# get the ID
Select * from INFORMATION_SCHEMA.PROCESSLIST

Next we can Search for the boundary name as demonstrated beneath.
Amazon RDS sets the default an incentive for innodb_file_per_table boundary to 1, which permits you to drop individual InnoDB tables and recover stockpiling utilized by those tables for the DB occasion. This rates up the recuperation time from the accident.
