Constraints

To ensure the stability and security of GaussDB(openGauss), certain constraints are put in place for access or permission control. Table 1 describes such constraints.

Table 1 Function constraints

Function Item	Constraints
Database access	Security group rules must be added to allow the ECSs to access GaussDB(openGauss) DB instances. By default, a GaussDB(openGauss) DB instance cannot be accessed by an ECS in a different security group. To allow it, you must add an inbound rule to the GaussDB(openGauss) security group. The default port is 8000. You can change it only when creating a DB instance.
Deployment	ECSs in which GaussDB(openGauss) DB instances are deployed are not directly visible to users. You can access GaussDB(openGauss) DB instances only through an IP address and a port number.
Database root permissions	Only the root permissions are available on the instance creation page.
Database parameter modification	Some parameters can be modified on the console.
DB instance reboot	GaussDB(openGauss) DB instances cannot be rebooted through commands. They must be rebooted on the management console.
Backup files	GaussDB(openGauss) backup files are stored in OBS buckets and are not visible to users.
