Administration of NAI Processes: The NAI Monitor
The NAI monitor provides an overview of all NAI processes
inside an SAP system. This means that all of
the activities surrounding the NAI Infrastructure can
be directly monitored inside the SAP system, for instance
the transfer of data between the SAP database
or the SAP archive and the NAI database. The
NAI monitor lists all NAI processes that belong to an
application or table, whereby detailed technical information
can be accessed on each individual process.
SAP administrators can use the NAI monitor to monitor
the entire infrastructure.

Access to Archived Data:
NAI-AS – the Extended SAP AS
PBS Nearline Analytic Infrastructure is simply ideal for
SAP customers who have consciously decided to go with
the SAP standard for archiving data. For instance, the NAI
Archive Information System represents an extension
of the SAP Archive Information System and offers a major
advantage in that archive indexes no longer need to
be stored on the database of the SAP system. Storage of
the archive indexes takes place in a compressed manner
inside the NAI database and offers all of the advantages of
a column-based database when it comes to accessing archived
data. The NAI-AS only needs to be activated once
in order to be put to use. The next step is to establish the
NAI data connection for the respective archive information
structure and activate it.
Activation of the NAI-AS results in new management of
the status so that the indexes from the database of the
SAP system can be copied over to the NAI database. These
indexes can be deleted from the database of the SAP system
once they have been transferred.

Using the NAI-AS does not change how users access archived
data via the Archive Explorer. Operating the NAI-AS differs
only slightly from how to use the SAP solution.
