问题 My node.js app gives 5xx due to connection timeouts at random times.

How to 'switch' from MySQL to Amazon RDS with minimal application impact?

由 孤街醉人 提交于 2019-12-09 14:40:46
问题 Amazon officially states: "Amazon RDS gives you access to the full capabilities of a familiar MySQL database. This means the code, applications, and tools you already use today with your existing MySQL databases work seamlessly with Amazon RDS." I don't get this. Amazon RDS is accessible via web services and there a client libraries (like the one for .Net). So if I have an existing .Net application that uses a DAL which in turn queries MySQL, how can I make the same DAL talk to the Amazon RDS

由 a 夏天 提交于 2019-12-09 06:12:30
问题 I am getting IO performance concerns with Amazon RDS using mysql 5.5.12. There are 2 instance types that are similar and close in price: Extra Large DB Instance: 15 GB of memory, 8 ECUs (4 virtual cores with 2 ECUs each), 64-bit platform, High I/O Capacity (MySQL DB Engine Only) ($0.88 per hour) High-Memory Extra Large Instance 17.1 GB memory, 6.5 ECU (2 virtual cores with 3.25 ECUs each), 64-bit platform, High I/O Capacity ($0.65 per hour) Does anyone know if the Extra Large DB has faster IO

AWS RDS Parameter Group not changing MySQL encoding

由 余生长醉 提交于 2019-12-08 22:21:31
I am running a MySQL database on RDS. I want to change all of my encodings to utf8mb4 . I created a parameter group on RDS with all character_set_* parameters as utf8mb4 , assigned it to my RDS instance, and then rebooted the instance. However, when I run SHOW VARIABLES LIKE '%char%' on my DB, there are still values of latin1 , which I do not want: character_set_client latin1 character_set_connection latin1 character_set_database utf8mb4 character_set_filesystem binary character_set_results latin1 character_set_server utf8mb4 character_set_system utf8 character_sets_dir /rdsdbbin/mysql-5.6.22

SQL Server Reporting Services for Amazon RDS

由 扶醉桌前 提交于 2019-12-08 16:14:21
问题 Recently, we have migrated a business application database to Amazon AWS SQL Server RDS. We have loved the flexibility of backup and scaling with the cloudified database, but we have need for writing reports for our gathered analytics data. Our in house data analyst is most comfortable using SQL Reporting Services. Normally, this is installed as a component with the SQL Server install, but we obviously do not have that option on RDS. My question is, has anyone been able to successfully deploy

can't connect to mysql on AWS RDS (error 2003)

由 a 夏天 提交于 2019-12-08 14:52:07
问题 I'm in trouble on setting up a MySQL RDS. From my EC2 instance I can connect fine, but from my laptop I get error 2003 (timeout). My RDS instance is configured to be publicly accessible. My security group has a rule inbound and outbound to allow all traffic everywhere (0.0.0.0/0). Should I configure something on my VPC or Internet Gateway? 回答1: As your security groups are wide open, my guess is that your LAN is blocking outbound traffic on port 3306. Infact, looking at this support page (
