21.3 Register node
Before a Tivoli Storage Manager client can use the storage services of a Tivoli
Storage Manager server, it must first authenticate to the Tivoli Storage Manager
server using a nodename and password. A node is created by the Tivoli Storage
Manager Administrator using the
register node command. In 8.2.3, “Working
with client nodes” on page 292, we show how to create client nodes.
When the node is registered, it has five key parameters: nodename, password,
domain, maxnummp, and backdelete. The Tivoli Storage Manager
backup-archive client defaults the nodename to the host name of the machine.
We strongly recommend registering a dedicated node for each Data Protection
backup client, that is separate from the node that is used with the backup-archive
client. If you have a separate policy domain for data protection backups, this is
required, since a node can only belong to one domain. The password you specify
will be used for authenticating the client API to the Tivoli Storage Manager server
the first time a Data Protection session is invoked.
Data Protection
for mySAP (DB2
or Oracle) Not required. You must define a
management class for SAP
system data, data files,
offline redo logs, and
copies of offline redo logs.
Data Protection for mySAP
uses its own
version
control
mechanism for
managing mySAP
database backups. To do
this, Data Protection for
mySAP backs up all data
only to management
classes for which an
archive copy group has
been defined. In addition,
to prevent backed up files in
Tivoli Storage Manager
being deleted because of
their expiration date, the
parameter retver should be
set to unlimited (9999).
