Management Issues In Lotus Notes Database

In the previous version of Lotus Notes, i.e. Lotus Notes 5.0 and earlier, the size limit of Domino database was limited to 4 GB. However, with the subsequent versions, the story is not the same. The users can store unlimited data in Domino server mailbox. However, the only problem with these versions is that above 4 GB, the database might give some performance issues, which can ultimately result in server crash. Therefore, keeping all these factors in mind, the limit up to which the database can store data is 4 GB.

Thus, it follows that for a particular server there might exist several 4 GB mailboxes, in order to save the server from crashing. However, this at times may get problematic for the Domino administrator. Managing a number of mailboxes may result in inefficiency of the administrator and additional efforts.

How To Merge Multiple Lotus Notes NSF Files?

As seen from the above section, multiple NSF files of 4 GB size limit can get difficult to be managed by the Domino administrator. Therefore, in order make it easy for the admin to manage the data, the NSF file need to be merged together. Merging multiple NSF Files enables the admin to manage the entire database at a single go.

It is to be noted, that there exists no manual by which, multiple NSF files can be merged together. Thus for this purpose NSF Merge proves to be the right solution for performing the merging of multiple NSF files. The merge and join options in the software merge the two or more NSF files in different manners. The software also gives the provision to exclude deleted and duplicate items from being merged.
