The purpose of the article is to list a procedure to change the password for "root" or "Health-check" user account on an active ScaleArc Cluster. A Health check user is the one which is used to add the Databases into a Scalearc Cluster. It can also be called the root user or an administrator. To use this article you will need the following information:
- Current Database creation user pasword for your cluster.
- Administrator user credentials to log in to the ScaleArc UI.
Before performing the password change for Health check user you must check the following:
a. The new password which you will give for Health check user must be same as used for logging in to your Databases.
b. The Health check interval should be increased to a sufficient interval to avoid DBs getting disconnected during this operation.
For setting this Health check interval from default 3 to 1000 during this operation please perform following steps:
This can be done by selecting "Cluster Settings" -> Server
Once the above is done you can now proceed for actual password change for the Health Check user as shown in steps below:
1. Login to your ScaleArc server as an Adminstrator user
2. Click "Clusters" at the top of the screen
3. On the Clusters page select "Users & DBs" under the "Settings" column
4. Click the Configure Users Database Icon next to the root user (theicon)
5. This will eventually get into the "Change password " option as shown below:
The old and new passwords can now be specified as explained before. When you click "Change Password" option as shown above - the password for Health check user gets changed to the new one.
Once the password change is verified and traffic passing through the cluster as before, then you must put the "Health-check attempts" value to its default of 3 instead of 1000 (which was a temporary measure).
