DFSORT UTILITY PDF

Closed as canceled. DFSORT is shipped with default options for this environment that generally provide efficient operation. However, you may want to change some of the INV options to better match your own environment for running DB2 Utilities. The following instructions illustrate the process for changing the DSA value to megabytes for use by DB2 Utilities. This is because DFSORT already performs storage hierarchy management the efficient balancing of processor memory and disk storage , and mixing this with VIO which uses processor memory results in suboptimal efficiency.

Closed as canceled. DFSORT is shipped with default options for this environment that generally provide efficient operation. However, you may want to change some of the INV options to better match your own environment for running DB2 Utilities. The following instructions illustrate the process for changing the DSA value to megabytes for use by DB2 Utilities. This is because DFSORT already performs storage hierarchy management the efficient balancing of processor memory and disk storage , and mixing this with VIO which uses processor memory results in suboptimal efficiency.

While DFSORT performs the initial work data set allocations with a primary space quantity of 0, it will attempt to extend them once the accurate amount of required space is determined.

Should a work data set reside on a volume which does not have sufficient space available, DFSORT invokes recovery routines that may result in the data set being deleted and re-allocated. While running concurrent utilities, if the percent free of your work pool is low, you can either reduce the number of concurrently running utilities or you can increase the number of volumes in your work pool.

DFSORT may abend or process inefficiently for large sorts when there is not enough main memory available, which can occur especially when the Utility runs many sorts in parallel. For large sorts when main memory is constrained, DFSORT will compensate with intermediate merges that increases the need for sort work data sets.

One method to avoid this is to ensure that there is sufficient main memory available for large sorts. Increasing the region size of the batch Utility job to accomodate the main memory needed for the parallel DFSORT tasks can allow the sorts to succeed. Local fix.

SYNCSORT Utility

Signed numeric with leading utilify sign. The minor control fields are specified following the major control field. The SORT control statement must be used when a sorting application is performed; this statement describes the control fields in the input records on which the program sorts. For example, the following are all equivalent: A short field is one where the variable-length record is too short to contain the entire field, that is, the field extends beyond the record.
