Do we have any restriction on the OAC instance name length?

Shyam-Oracle

REST API to create OAC instances are failing with below error. Seems like this is due to instance name size restriction to 25 characters, Was this introduced recently? This was working before with instance name greater than 25 characters as well. I did not find any documentation on this size limit.

Error:

Caused by: com.oracle.bmc.model.BmcException: Error returned by CreateAnalyticsInstance operation in Analytics service.(400, InvalidParameter, false) OAC-REST-002000: Input validation error for attribute "name": size must be between 1 and 25 (opc-request-id: 883387EFD73E44B7A03EB91C41651456/E0A8C36A94D33FD44370116949414429/F9413F3FBD5CDC86FE2C187CF654590B)

Hi Shyam,

There are several restrictions to consider when choosing a service name, please check the following list:

Must contain between 1 and 25 characters.
Must start with an ASCII letter: a to z or A to Z.
Must contain only ASCII letters or numbers.
Mustn't contain any other special characters.
Must be unique within the identity domain.

these are documented here: https://docs.oracle.com/en/cloud/paas/analytics-cloud/acoci/what-name-do-you-want-your-service.html

Hope this helps!

Thank you Aman, This helps. Do you know if this was changed recently? We have few instances created in Mar-May time with name greater than 25 chars length.

Hi Shyam, I am not sure if this was changed recently.
