DMS Configuration For Migration From RDS To MariaDB On EC2

Hi,

In order to view if the instance in under resource contention you can have a look at the metrics of the replication instance:

https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Monitoring.html

Further in order to troubleshoot the task, I would suggest you analyze the task logs and also you can have a look at the below link:

hi sahil
thanks for your informations.
i already update DMS instance to dms.r4.large
i have 23 task replication
and for each task i have configuration like this
FULL LOB (LOB Chunk size 8 kb)
enable validation
enable cloudwatch logs

advance task setting
maximum number of tables to load in pararell = 1
commit rate during full load = 1
transaction consistency = 600 seconds

currently i still got error message everyday
Message : Replication task has failed.
Reason: Last Error Replication task out of memory. Stop Reason FATAL_ERROR Error Level FATAL

but there is random task from 23 task replication

any advice ?

thanks
