# Plans Configuration
# Using more than one DNS server
Question: Can I assign multiple DNS servers when setting up a plan?
Answer: PanelAlpha allows only one DNS server to be added to a plan. To have backup DNS servers, you can use cPanel's DNS synchronization. More details can be found in the cPanel documentation (opens new window).
# Error when installing an instance
Question: Every time I create an instance, Plesk uses the dedicated IP. How can I set it to use the shared IP by default?
Answer: You can select the IP address used to create the instance in the Hosting tab of your plan configuration. Selecting the shared IP type should resolve this issue.
# Automatically creating subdomains
Question: Is it possible for a client to automatically create a subdomain during the order process?
Answer: To automatically create subdomains, follow these steps:
- Use the Quick Onboarding or Super Quick Onboarding methods, and:
- Ensure the "Ask for domain" option is disabled.
- Set the main domain in the "Domain used for subdomain" field.
- Select the desired configuration in the "Automatic subdomain format" options.
# Memory limit in PanelAlpha engine
Problem: Error: Error 137: Out of Memory
Solution: Increase the memory limit in the plan configuration and upgrade the plan. This can be done in the admin area by selecting "Upgrade" and reapplying the same plan.
# Changing server IP address vs. changing IP on services
Problem: After changing the server IP (PanelAlpha Engine), the associated services do not reflect the new IP address.
Solution: IP address changes only apply to the newly created services. Existing services will not be updated unless they are removed and recreated.
# Changing DNS server in plan configuration
Problem: After changing the DNS server and selecting the "Create A record on parent zone" option under "Subdomain DNS Action," issues with creating instances on subdomains persist.
Solution: DNS server changes in the plan configuration only apply to the newly created services. To apply these changes to existing services, they must be removed and recreated, as the updates do not automatically affect them.
# CPU limit exceeds available resources
Problem: Error response from daemon: Range of CPUs is from 0.01 to 2.00, as there are only 2 CPUs available
Solution: Make sure CPU Limit in Hosting tab in Plan is lower than number of CPUs on your PanelAlpha Engine server.
