Parameter Value Limits

Last updated: 2023-09-10 09:03:04

On this page:

Due to factors such as resource specifications, modifications to certain instance parameters may be subject to limitations. This article primarily discusses parameters that are constrained by instance specifications and their respective constraint values.

Supports and Limits

Setting the following parameters will use system resources. To prevent the database use from being affected by parameter values, configure them as needed.
Note
Some are key parameters, and changing them may affect your use or the normal running of the instance. Therefore, exercise caution when modifying key parameters.
