The server provides the capability to store documents and folders in a hierarchy (documents within a folder within another folder). Document library objects (DLOs) are documents and folders.
To simplify storage management, the server stores all DLOs in one or more libraries. The name of the library in the system ASP is QDOC. Each user ASP that contains DLOs has a document library called QDOCnnnn, where nnnn is the number that is assigned to the ASP. From a user perspective, DLOs are not in libraries. The server files them in folders. You manipulate DLOs by using DLO commands and menus.
Some licensed programs use DLO support.
Within the integrated file system, the QDLS (Document Library Services) file system provides DLO support.
The server uses a set of search index files in the QUSRSYS library to keep track of all the DLOs on the server. The names of these database files begin with the characters QAOSS. The server uses other QAO* files in the QUSRSYS library to track distributions and support text search capabilities. You should periodically save these files in QUSRSYS. Menu options 21 and 23 of the GO SAVE command save both library QUSRSYS and all the DLOs on the server.
You can use the Save Document Library Object (SAVDLO) command to manually save one or more documents. This does not affect documents unless you specify the settings to free or delete storage. You can save a single document or more than one document.
