skip_proxy_sys_private_check

Last Updated：2025-03-21 09:20:28 Updated

skip_proxy_sys_private_check specifies whether OceanBase Database Proxy (ODP) skips checking the private address of the system.

Note

In OceanBase Database Proxy (ODP) Community Edition, the default value of this parameter has been changed from True to False since V4.2.1, to keep consistent with the Enterprise Edition.

Attribute	Description
Parameter type	Boolean
Default value	False
Value range	`True`: specifies to skip checking the private address of the system. `False`: specifies not to skip checking the private address of the system.
Effective only after ODP restart	No
