If your AS/400 is heavily used by word processing users, it may be of interest to you that document storage and use consumes very large amounts of disk and that there are no simple ways to determine how much disk is used for Document Library Object (DLO) storage on the AS/400. Further, you may have wondered if there is any way to ascertain how old the documents in the various folders are, i.e., how long since they were last used. This information could be used to encourage users to purge or archive older documents. Also, AS/400 managers should be aware of the RGZDLO command, whose purpose is similar to the CONDENSE command on the S/36. The RGZDLO command reorganizes a folder on the AS/400, returning as much as 30 percent of the space to the system. My own folder, after a RGZDLO was run, shrank from 8MB to 5MB of used space. RGZDLO can be run against a single folder or all folders in the system. If you run for all folders, you should allot a large time span for its completion. Depending on the number of users who are actively engaged in word processing, it could take over five hours to compress all the folders. On our system there are 650 folders and we determined that an overnight RGZDLO would take six hours.

Shown here are3a, 3b, 3c, and 3d which can be used to analyze the contents of folders to determine the age of documents (last date changed). 3a lists the Analyze Folder Documents (ANZFLRDOC) command. 3b has the CPP (program FLR001CL), which uses the DSPFLR command to create an outfile which is then read to create another outfile with one record for each document. 3c is RPG program FLR001RG, called by FLR001CL, which plays games with the date field to compute the age. A word of explanation: the date field in the outfile is in edited form, i.e., with imbedded slashes and cannot (as far as I know) be used for date computations. Notice that the RPG program uses program-defined file definitions, even though the outfile created is externally defined.

Shown here are Figures 3a, 3b, 3c, and 3d which can be used to analyze the contents of folders to determine the age of documents (last date changed). Figure 3a lists the Analyze Folder Documents (ANZFLRDOC) command. Figure 3b has the CPP (program FLR001CL), which uses the DSPFLR command to create an outfile which is then read to create another outfile with one record for each document. Figure 3c is RPG program FLR001RG, called by FLR001CL, which plays games with the date field to compute the age. A word of explanation: the date field in the outfile is in edited form, i.e., with imbedded slashes and cannot (as far as I know) be used for date computations. Notice that the RPG program uses program-defined file definitions, even though the outfile created is externally defined.

Another word of warning. The age routine will only work for the 20th century. If you are under 55 years of age, you should consider using a modified computation routine, since you will still be working in 2000.

To determine the size of folders, see 3d. This will produce a file containing one record per document. The file can be read by a Query or RPG program to list a summary for each folder. The outfile is externally described by the system and contains, as one of the fields, the object size. The folder name is the system name, not the user's.
