This section provides an overview of typical tasks that arise when working in a MAREN network with domains.
Changing administration areas
The administrative tasks in a MAREN network with domains are shared between All-Domain Administrators (ADAs) and Domain Administrators (DAs). A DA can switch to the role of the ADA and vice versa. The DA and ADA must always be authorized to work with the MARENADM program (see chapter “MARENADM administrator program”).
DA becomes an ADA
DAs can only switch to the role of the ADA if they are working on a system which is authorized for the ADA (see step 4). A DA proceeds as follows:
Quit MARENADM:
//HOLD-PROGRAMEnter the ADA password in BS2000:
/ADD-PASSWORD PASSWORD=<password>Return to MARENADM:
/RESUME-PROGRAMLog on as ADA:
//MODIFY-ADMINISTRATION-SCOPE DOMAIN=*ALL
If the ADA role is not password-protected, the last step alone is sufficient.
ADA becomes a DA
If the ADA takes over the role of the DA of a domain, he/she switches to the relevant domain. In this case he/she selects a system whose system-specific parameters apply for his/her other statements.
The ADA switches to the domain://MODIFY-ADMINISTRATION-SCOPE DOMAIN=<dom>(HOST=<system>)
This statement is also required if the ADA is already working on a system in the domain which he/she wants to administer as the DA. In this case the ADA enters DOMAIN=*OWN. It is not necessary to specify a host (HOST=) as the system-specific parameters of the user’s own host will become effective.
Modifying the assignment of tapes to domains
Only the ADA is authorized to assign tapes to another domain. This is done using the MODIFY-VOLUME-ATTRIBUTES statement with the SELECT operand.
Example
The ADA now assigns all reserved tapes of domain DomAAA to domain DomCCC://MODIFY-VOLUME-ATTRIBUTES SELECT=*RESERVED(DOMAIN=DomAAA,NEW-DOMAIN=DomCCC)
Adding new systems to a domain
Only the ADA is authorized to add a new system to the MAREN network and in the process to a domain. The ADD-HOST statement is used for this purpose. Using the PARAMETER= operand the ADA defines the other system from which the system-specific parameters are taken over. Naturally these parameters can subsequently be modified. Only when the system is assigned to the network and domain MARENCP can be started on this system.
Example
System System05 is assigned to domain DomBBB://ADD-HOST HOST=System05,DOMAIN=DomBBB
Assigning a system to another domain
Only the ADA is authorized to assign a system to another domain. The MODIFY-DOMAIN-ASSIGNMENT statement is used for this purpose.
Example
The ADA assigns the system System02 to domain DomCCC://MODIFY-DOMAIN-ASSIGNMENT HOST=System02,NEW-DOMAIN=DomCCC
