Hello
The amount of RAM you need for a 2019 RDS server for 30 concurrent users running an Oracle-based client can depend on several factors, including the specific requirements of the application and the usage patterns of your users. However, here are some general guidelines:
Per User Requirement: As a rule of thumb, you might want to allocate between 2 and 8 GB per user. This would mean for 30 users, you’d need between 60 GB and 240 GB of RAM.
Operating System Requirement: You should reserve 1 GB RAM for the OS, plus an additional 1 GB for every 4 GB between 4-16 and another 1 GB for each 8 GB above 16 GB.
Application Requirement: The specific requirements of your Oracle-based client application can also affect the amount of RAM you need. You may want to check the documentation for your specific application or reach out to the vendor for more precise information.
Please note that these are just guidelines and the actual amount of RAM you need could be different based on your specific use case. It’s always a good idea to monitor your server’s performance and adjust as necessary. If you find that your server is frequently running out of memory, you may need to add more RAM.
