PSSR output
PSSR output consists of the unloaded database and some printed reports.
The unloaded database records are contained in the following data sets:
- For non-HALDB databases
- SORTOUT data set
- Contains segment records that will be reloaded into the home block.
- SORTOUT2 data set
- Contains segment records whose root segment will not fit into their respective home blocks if the input DBD organization is HDAM.
These data sets are then used as input to either the IMS™ HD Reorganization Reload utility or its equivalent reload utility. When used in the reload step, they must be concatenated, with SORTOUT being the first data set.
Important: If you reload an HDAM database by using IMS High Performance Load for z/OS® Version 2 Release 1 or later, you cannot use SORTOUT2 as an input for the reload. For details, see Considerations before using PSSR.- For HALDB databases
- Either of the following data sets:
- SORTOUT data set
- Contains segment records sorted in partition sequence and, in each partition, sorted in physical sequence. Any segment record whose root segment does not fit into its home block (according to the PSSR algorithm) are placed at the end in each partition.
- Output partition data set
- Contains all the segment records that need to be reloaded into one partition.
Unlike non-HALDB databases, the SORTOUT2 data set is used as a work data set for PSSR. You must not reload the segments that are contained in this data set.
If the randomizing routine returns a return code of 4 for a root segment, the database record that contains that root segment is put into the SORTOUT3 data set, if it is specified in the JCL. This data set must not be used as an input for the previously mentioned reload utilities.
If the DL/I partition selection returns a nonzero return code for HALDB processing, and if SORTOUT4 is specified in the JCL, the database record that contains the root segment is put into the SORTOUT4 data set. This data set must not be used as an input for the previously mentioned reload utilities.
If the SORTOUTD DD is specified, the database record that contains the duplicate root key segment is put into the SORTOUTD data set. You must determine whether this data set is to be used or not as an input for the previously mentioned reload utilities.
The PSSR reports are generated in the following five data sets:
