A library is a collection of documents and document properties stored in a database system that can be managed and searched. You do not need to set up libraries unless you are using GroupWise Document Management Services (DMS). See Section VII, Libraries and Documents.
The databases for managing libraries are stored in the gwdms directory and its subdirectories in the post office.
The dmsh.db file is a database shared by all libraries in the post office. It contains information about where each library in the post office is located.
Each library has its own subdirectory in the gwdms directory. In each library directory, the dmxxnn01-FF.db files contain information specific to that library, such as document properties and what users have rights to access the library.
For the location of library databases in the post office, see GroupWise 2012 Troubleshooting 3: Message Flow and Directory Structure. For more post office information, see Section 35.3, Information Stored in the Post Office.
The actual documents in a library are not kept in the library databases. They are kept in a document storage area, which consists of a series of directories for storing documents. Documents are encrypted and stored in BLOBs (binary large objects) to make document management easier. A document, its versions, and related objects are stored together in the same BLOB.
A document storage area might be located in the post office itself, or in some other location where more storage space is available. If it is located in the post office, the document storage area can never be moved. Therefore, storing documents in the post office directory structure is not usually recommended. If it is stored outside the post office, a document storage area can be moved when additional disk space is required.
