I have an on-premises MySQL database that needs to be migrated to an AWS RDS MySQL database. The on-premises database will be updated regularly, and I want to update the RDS database with the latest records from the on-premises database on a daily basis at a scheduled time. The two databases have schema differences, and I need to modify the data from the on-premises database to match the schema of the RDS database. I will not be performing any analytics on the data, and the RDS database will be used as the database for a web application.
Can you suggest an ideal approach for this scenario?
Thanks in Advance!
Im trying to find a way, to make the multi-az cluster read replica, to become writable.
Is it even possible? or the only way of "promoting" the read replica, to be writable, is to "failover" the primary instance?
We have been providing AR web services since March 17th. Normally, the RDS CPU usage was only up to 4-5%, but there was a history of it using up to 60% today, so we are investigating the cause. Currently, RDS is created in a private area, and we understand that it can only be accessed by EC2 created in the same VPC. We checked the access logs of the Ubuntu EC2, but it seems that only two workers accessed the EC2 with their IP addresses. We are wondering if there is any other way to access the private RDS, and if CPU resources can be used like this when automatic RDS backups are performed. The RDS specification is db.m5.large, and MariaDB and the EC2 specification is c5n.2xlarge Ubuntu. Approximately 1 minute later, CloudWatch logs showed [Warning] Aborted connection numbers to db: 'unconnected' user: 'rdsadmin' host: 'localhost' (Got an error reading communication packets).
A question for the AWS professionals.
I recently worked with a dev team to create a web app for my business. The infrastructure is aws rds (db.m6i.large, 100% utilization, ondemand, multi-az) s3, and lightsail. Cost are estimated to be $300 p month in the calculator but we are being charged $1000 p month. Anyone know why we are charged so much?
Request: Delete 2 parameter groups?
Are you sure you want to delete these DB parameter groups
default.mysql8.0
default.mysql8.0
Unable to delete, getting the following error:
Failed to delete default.mysql8.0: Default DBParameterGroup cannot be deleted: default.mysql8.0 (Service: AmazonRDS; Status Code: 400; Error Code: InvalidDBParameterGroupState; Request ID: 4463730b-4e33-4ccf-ba4a-3ba533a9d6b2; Proxy: null).Failed to delete default.mysql8.0: Default DBClusterParameterGroup cannot be deleted: default.mysql8.0 (Service: AmazonRDS; Status Code: 400; Error Code: InvalidDBParameterGroupState; Request ID: 57478ad0-cd52-456b-9f16-9cdc678fba58; Proxy: null).
I am new to AWS and have been getting billed for this but I am unable to figure this out. Any help would be greatly appriciated.
RDS Custom for SQL Server is a managed database service where the customer has full administrative access to the operating system and database configuration, including via RDP. New OS images are provided regularly with the latest patches. Assuming there are no critical patches to apply, about how much time would elapse between new versions?

I've recently upgraded my database from mysql5.7 to mysql8.0.26 which also incorporated an upgrade from Aurora 2 to Aurora 3 which is where I think the issue lies as there are no references to the following issue in the mySQL documentation.
During the upgrade the myql.user table is copied to the new database (using a Blue/Green deployment). GRANT permissions are also copied across and all the details remain unchanged as I have verified with `SHOW GRANTS` on both the blue and green environments. However, my users in the mysql8 DB do not have access to the resources identified in the GRANTS where those resources contain an underscore.
To reproduce the issue:
1. Create an Aurora 3 DB instance running MySQL 8.0.26
2. CREATE SCHEMA new_schema ;
3. CREATE TABLE new_schema.test_table (id int);
4. GRANT ALL PRIVILEGES ON `new\_schema`.* TO `my-user`@`%`
Run `SHOW GRANTS for my-user;` and you will see the following response:
```
GRANT ALL PRIVILEGES ON `new\_schema`.* TO `my-user`@`%`
```
That is the expected response, and mySQL documentation advises keeping the escape character in place to avoid any issues related to partial_revokes (which I can confirm is OFF by default).
Now the problem is, in Aurora 3, if I log in with `my-user` and run `SELECT * FROM new_schema.test_table` I get a permission denied error.
I have investigated a similar sounding issue in re:post [here](https://repost.aws/questions/QUeD79WVUQT4WJ9bpMNJ7hfg/aurora-3-my-sql-the-value-of-the-partial-revokes-parameter-in-the-parameter-group-is-different-from-the-value-of-the-same-variable-in-my-sql) however, I have already confirmed that `partial_revokes` as set to 0 (disabled) both in my database parameter groups and if I query it directly in mysql.
**** I found the answer which is reserved RDS instances can't move region. ***
Hi,
We are planning to move our AWS resources from eu-west-1 to eu-west-2. Before that happens some of our RDS reservations will expire.
Will we have to take the hit of non reserved pricing until the move is complete, or can reserved RDS instances be moved to a different region?
Thanks for your input.
Hi,
Im getting this strange error:
```
ERROR 1227 (42000): Access denied; you need (at least one of) the GRANT OPTION privilege(s) for this operation
```
Trying to run this command on "writer instance" of "multi-az cluster":
```
grant replication slave, replication client, replication_slave_admin on *.* to 'repl'@'%';
```
Knowing that the same command works on the "multi-az" "writer instance", im confused.
Hi,
Logged on as the m aster user on a Oracle 19 RDS database, I would like to execute the following:
GRANT EXECUTE ON XDB.DBMS_XMLSCHEMA TO appl_owner;
This fails with ORA-01031: insufficient privileges.
I tried this with RDSADMIN package:
EXECUTE rdsadmin.rdsadmin_util.**grant_sys_object**( p_obj_name=>'DBMS_XMLSCHEMA', p_grantee=>'FWD_OWNER', p_privilege=>'EXECUTE');
But that want to grant privileges on SYS objects, so it doesn't find objects in schema XDB.
How can I grant privileges on objects in different schema (xdb) to o different user/schema?
Thanks
I want to make some database operations with GUI and what is the best option for this project? To run my project i'm using xampp and I would like to be able to run queries on my database and dynamically display, sort, add, remove, and update records based on site user input. Should I use a RDS database or EC2?
Hello AWS,
I have a Client requirement to create a USER and Grant ALL PRIVILEGES to this newly created USER. These SQL Queries are working on my on-premises Oracle Database but when executing the same in AWS's Oracle RDS instance, the Query is not working for my newly created user it shows the privileges error! I'm unable to give ALL PRIVILEDGES for newly created USER in RDS. Have pasted and attached the following queries and the Error faced.
alter session set "_ORACLE_SCRIPT"=true;
create user mendix_so_8_10 identified by 1;
GRANT ALL PRIVILEGES TO mendix_so_8_10;
Kindly Requesting your team to give us a working solution to our problem. Awaiting your reply at the earliest.
Thanks & Regards,
Madhumitha. B
