DASD storage required for the target system

High Level Assembler libraries can reside on any currently supported DASD.

Table 1 lists the total space required for each type of library. The values are for a 3390 DASD.

Table 1. Total DASD space required by High Level Assembler
Library Type	Total Space Required
Target	72 Tracks
Distribution	76 Tracks

Table 2 gives an estimate of the storage requirements for SMP/E work data sets, for High Level Assembler.

Notes:

The data set sizes specified contain 15% extra space. You may wish to revise these numbers based on your plans for adding additional function or service.
IBM recommends use of system determined blocksizes for efficient DASD utilization for all non-RECFM U data sets. For RECFM U data sets, IBM recommends a blocksize of 32760, which is the most efficient from a performance and DASD utilization perspective.
If you choose not to use system determined blocksizes, use the blocksizes and numbers of blocks specified to allocate the data sets. Data sets can be reblocked to a larger size. The maximum allowable blocksize depends on the type of DASD on which the dataset will reside.
Abbreviations used for the data set type are:
U

Unique data set used by only the FMIDs listed. In order to determine the correct storage needed for this data set, this table provides all required information; no other tables (or program directories) need to be referenced for the data set size.

S

Shared data set used by more than the FMIDs listed. In order to determine the correct storage needed for this data set, the storage size given in this table needs to be added to other tables (perhaps in other program directories). If the data set already exists, it must have enough free space to accommodate the storage size given in this table.

If you currently have a previous release of this product installed in these libraries, the installation of this release will delete the old one and reclaim the space used by the old release and any service that had been installed. You can determine whether these libraries have enough space by deleting the old release with a dummy function, compressing the libraries, and comparing the space requirements with the free space in the libraries.

For more information about the names and sizes of the required data sets, refer to Table 4 and Table 5.

Table 3 provides an estimate of the storage needed in the SMP/E data sets for High Level Assembler. The estimates must be added to those of any other programs and service being installed to determine the total additional storage requirements.

Table 4 and Table 5 list the target and distribution libraries and their attributes required to install High Level Assembler. The storage requirements of High Level Assembler must be added to the storage required by other programs having data in the same library.

You can access the supplied sample JCL after the SMP/E RECEIVE step in the install process. Alternatively, you can copy the sample JCL directly from the installation tape into a temporary library. If you use this method, use the data set requirements shown in Table 6.
