CA IDMS/DB Reorg uses work files that vary in size. These files are sequential with the exception of the PAGUTIL file which must be RRDS VSAM or relative record BDAM. If VSAM, the PAGUTIL file must be NUMBERED.
Each work file requires a certain amount of space when you assign it to disk. Calculate the space for every file, except the EXTRACT file, by using the number of records (from the CA IDMS/DB Analyzer reports or from your own sources) and the information given for estimating work file space in the following figures. To determine the space allocation for the EXTRACT file, use the number of extracts per record listed on the CA IDMS/DB Reorg Audit Report (Audit Subreport--Set Linkage Recap for Area) in addition to the number of records listed on the CA IDMS/DB Analyzer Set Report.
When you use the information in the following figures to estimate the space required for the files, you may find that some files require more disk space than you have available; these files may be assigned to tape (except PAGUTIL).
File attributes such as RECORD LENGTH and RECORD FORMAT are defined internally and should not be coded in the JCL statements. The default BLOCKSIZE may be overridden, but it must conform to the information in the following figures.
