GUC Parameter Usage

A database provides many operation parameters. Configurations of these parameters affect the behavior of the database system. Before modifying these parameters, learn the impact of these parameters on the database. Otherwise, unexpected results may occur.

You are advised to modify some parameters on the GaussDB console. If the parameters cannot be modified on the console, evaluate the risks and contact customer service.

Precautions

  • If the value range of a parameter is a string, the string should comply with the naming conventions of the path and file name in the OS running the target database.
  • If the maximum value of a parameter is INT_MAX, the maximum parameter value varies by OS. INT_MAX indicates the maximum value of the INT data type. The value is 2147483647.
  • If the maximum value of a parameter is DBL_MAX, the maximum parameter value varies by OS. DBL_MAX indicates the maximum value of the FLOAT data type.
