amazon-rds

I have a Java EE application running in GlassFish on EC2, with a MySQL database on Amazon RDS. I am trying to configure the JDBC connection pool to in order to minimize downtime in case of database failover. My current configuration isn't working correctly during a Multi-AZ failover, as the standby database instance appears to be available in a couple of minutes (according to the AWS console) while my GlassFish instance remains stuck for a long time (about 15 minutes) before resuming work. The connection pool is configured like this: asadmin create-jdbc-connection-pool --restype javax.sql

I am not able to figure out how to implement this. Any help and/or pointers will be greatly appreciated. Currently, my Java/Spring application backend is deployed on EC2 and accessing MySQL on RDS successfully using the regular Spring JDBC setup. That is, storing database info in application.properties and configuring DataSource and JdbcTemplate in @Configuration class. Everything works fine. Now, I need to access MySQL on RDS securely . RDS instance has IAM Authentication enabled. I have also successfully created IAM role and applied inline policy . Then, following the AWS RDS documentation

How do I change the configured RDS endpoint of an AWS Elastic Beanstalk environment? E.g. after the RDS database was deleted or should be replaced with a new RDS database. Update The topic remains complex and the AWS Elastic Beanstalk (EB) documentation could still do a better job to clarify available options. The question has been about how to change an RDS endpoint , which seems to be read in two different ways: One could interpret it about how to attach an existing externally managed RDS endpoint to an existing (not new!) EB environment - this is indeed not possible, rather one would need

I recently downgraded my EC2 instance. I can no longer connect to RDS. I think it might be that the internal IP is different and now the logins are attached to that specific IP. I haven't been able to figure it out. I would like to be able to get a backup from the snapshot. Is there a way to download it through AWS? You can't download an RDS snapshot. You can however connect to it and export your databases. Downgrading your instance should not affect connectivity unless you had set up your security groups incorrectly (Opening ports to an IP instead of another security group). abguy In addition

I am creating an RDS instance using CloudFormation using this: "Resources": { "myDB": { "Type": "AWS::RDS::DBInstance", "Properties": { "AllocatedStorage": "5", "DBInstanceClass": "db.m1.small", "Engine": "MySQL", "EngineVersion": "5.5", "DBName": "mydb", "MasterUsername": { "Ref": "DBUser" }, "MasterUserPassword": { "Ref": "DBPassword" }, "DBParameterGroupName": { "Ref": "myRDSParamGroup" } } } and it all works. But I need to run initial SQL on the DB when its created, to setup my apps schema. My current approach is to have the app self migrating, but I'd like to do it in the CloudFormation
