Service account

On a Management Unit the service account is provided for Customer Support on the base system. Under this account the service engineer works on all available interfaces (web interface, Linux desktop of the local console, shell level), both locally on site and also remotely via the remote service access.

The service account can also access the BS2000 console. The following must be taken into consideration when logging entries on the BS2000 console:

• In the KVP logging files it is possible to distinguish the account (e.g. admin or user1) under which an entry was made.

• In BS2000, on the other hand, only the console mnemonic (e.g. C0) enables you to recognize who made an entry in the CONSLOG files.
  Consequently console entries of different users are only unambiguously identifiable if every user uses a different console mnemonic when accessing the console.
  To achieve such differentiation, you can assign the operator accounts different console MNs (by means of individual access rights). For administrator accounts, BS2000 administrator accounts and in particular for Customer Support, it is only possible to reach an agreement on using particular unambiguous console MNs.

Security-relevant actions

• Change the console mnemonic for operator accounts
  In the SE Manager, Authorizations -> Users -> Individual rights enables you to enter the console access to a system with a specific console MN. The change takes effect immediately.
• Define the console mnemonic in the BS2000 operating system
  It must be ensured that the assigned console mnemonics are defined in BS2000 so that the console access functions.
  You define the console MNs in the /BEGIN OPR section of the BS2000 parameter files (e.g. SYSPAR.BS2.nnn) using the keyword DEFINE-CONSOLE. Here the TELESERVICE=YES parameter ensures that the console is not taken away from Customer Support (i.e. the console cannot become either a standby console for another console or a master).
  Details on configuring the console mnemonic are provided in the manual “Introduction to System Administration” [8].
