When you work with IBM Lotus Notes, your entire mailbox data is stored in Lotus Notes database file known as NSF file. Like any other database file, NSF files are also sensitive files that can get corrupt due to various reasons. These reasons may vary from server crash, interference of any third-party add-in, improper ways of handling and data accessing from NSF file, and many such issues. Since corruption causes complete inaccessibility of all the data stored in your Lotus Notes mailbox, it should be avoided.
At times, despite various attempts for preventing your NSF database file from getting corrupt, you suspect or encounter its corruption. In such situations, you can try below mentioned inbuilt utilities of IBM Lotus Notes for resolving these issues and repairing the database:
FIXUP: In order to attempt of resolving the issue with your NSF file, the inbuilt ‘FIXUP’ task can be the first tool. Before running ‘FIXUP’, you should know the type of the database so that you can work accordingly. If the target database are system database like ‘names.nsf’, or ‘log.nsf’, then all the tasks associated with it must be stopped before using this fixing method. More precisely, this method performs a general check of your NSF file and repairs it, if finds any errors. For running the command associated to this method of NSF repair, you have to open the command prompt and change the directory to Lotus Notes program directory. After doing the same, enter the following command:
nfixup.exe X:/.nsf and then press ENTER.
COMPACT: Like you did before running FIXUP; analyze the type of database prior to running COMPACT task. This is to make sure that no database related activity is running for the duration of the task and should terminate before its completion, if any entity or object opens this database for read/write during this task. Furthermore, the type of compaction used by this feature of Lotus Notes is ‘copy-style’ compact, and according to it no user related to this database should access it during the compact. Here as well you have to open command prompt for running the command associated to compact:
Type the following command on the command prompt: ncompact.exe X:/.nsf and press ENTER.
UPDALL: This command is used when the corruption is specific to the view or views in your database. Basically UPDALL is for rebuilding the entire NSF index. For running this command, select your database or view and type the following command on the command prompt:
Nupdall –r X:/.nsf and press ENTER.
However, if these inbuilt commands of Lotus Notes fail to do any needful, then use of a professional Lotus Notes recovery tool is recommended. Reliable and efficient Notes recovery software repairs damaged Lotus Notes files and recovers all the objects contained in it. The simple user interface and understandable steps of these tools make them an easily operable method for repairing the corruption of NSF database files and restoring their data. Moreover, if you do not know the location of your NSF file, then most of the tools facilitate you to search it in any folder, sub-folder, or entire volume in your computer.
