There might be occasions when it is necessary to change the passwords for the Application User or Application Administration User accounts. When changing the password manually, it must be changed in the following places:
The required User account; either Application User or Application Administration User.
The process identities. All processes running under the User identities need to have their configurations updated with the new password. Refer to The Application User and The Application Administrative User, for list of these processes.
In addition, the Change Database User Password Tool needs to be used to change the Database User’s password for all database users. Refer to Change Database User Password.
