DD names for the Index Builder task
This topic describes DD names used for the Index Builder task. These DD statements are not necessary if INDEXBLD=YES or PSINDEXBLD=YES is not specified.
- sindex DD
- Defines the output data sets for all secondary indexes to be rebuilt. If INDEXBLD=YES or PSINDEXBLD=YES is specified and the dynamic allocation of the data sets are not designated, the DD statements must be specified. The DD names must be those defined in the DBD that is to be used for the Index Builder task. The data set must reside on a direct-access device. If you use dynamic allocation, do not code the DD statement for the database data sets. For details, see Secondary indexes.
- IIUPRINT DD
- Defines the primary statistics output data set for the Index Builder task. The data set contains reports and statistics produced by IMS Index Builder. When the DD statement is omitted, the DD statement is dynamically allocated to the SYSOUT stream of the output class specified by the MSGCLASS parameter on the JOB statement.
- IIUCAPT DD
- This output file contains the combined WTO messages from the sort address spaces that are involved in the process. If the DD statement is not coded, the DD statement is dynamically allocated to the SYSOUT stream of the output class that is specified by the MSGCLASS parameter on the JOB statement.
- IIUDUMP DD
- This output file contains a dump that is generated as the result of an error.
- IIUSNAP DD
- This output file contains major processing event logs. This DD statement is optional, and if the DD statement is not coded, the DD statement is dynamically allocated to the SYSOUT stream of the output class specified by the MSGCLASS parameter on the JOB statement.
- IIUSOUT DD
- Defines the sort output data set for the Index Builder task. The
data set contains the output from each sort task attached or started
by the Index Builder task. If a sort error is encountered, this file
must be inspected because it contains detailed sort messages.
If the DD statement is not coded, the DD statement is dynamically allocated to the SYSOUT stream of the output class that is specified by the MSGCLASS parameter on the JOB statement.
