This section describes how to change the passwords for users admin, GaussDB, and db_user by using the omutool, how to change the password for user FtpUsr by using the MML command, and how to log in to the U2020 to change its FTP user's password.
· admin is the administrator account for logging in to the LMT.
· GaussDB is the default internal account of the database and cannot be deleted. GaussDB is used for database initialization.
· db_user is the account for accessing the OMU database.
· FtpUsr is the account for uploading and downloading files to and from the OMU.
· An FTP user of the U2020 is used for the U2020 to access BSC6900 for file loading and downloading.
· The following procedure assumes that version_a is the OMU active workspace. Run the LST OMUAREA command to query the OMU active workspace.
· If active and standby OMUs are configured on the BSC6900, you must change the passwords of users admin, db_user, and GaussDB on both the active and standby OMUs.
NOTE:
§ Single-OMU mode: Stop the omud before the change and restart the omud after the change.
§ Dual-OMU mode: Stop the standby omud and then the active omud before the change. Restart the active omud and then the standby omud after the change.
§ You are advised to change the password upon your first login and change the password every subsequent three months. The initial password of user db_user is MBSC_db_2008. The initial password of user GaussDB is a random value with 8 to 32 bits automatically generated during database initialization.
§ The passwords of db_user and GaussDB must contain uppercase letters, lowercase letters, digits, and special characters (-?[]_+{}). The password length must range from 8 to 32 characters.
§ The passwords of admin must contain uppercase letters, lowercase letters, digits, and special characters (~!@#$^*()_+-{}|[]:./). The password length must range from 8 to 32 characters.
Keep the password safe. You need to reinstall the OMU operating system if the password is lost.
