BMC AMI Fast Path Indexer for IMS capabilities

partition an index

You can build a partitioned index and include as many as 500 partitions in the index. Each partition can be up to 4 GB.

process an index as a stand-alone database

You can process an index that was created with BMC AMI Fast Path Indexer for IMS as a stand-alone database for retrievals. This processing method lets you retrieve information while improving system performance.

create 500 indexes

Whether you choose the SHISAM structure or the HISAM structure, you can build up to 500 indexes. If you partition an index, you can include 500 partitions.

create index keys from five source fields

You can use up to five fields from the primary DEDB segment to create the index key. You can use any field in the segment as the key in the index. If the primary DEDB data is not unique, you must use the subsequence field to force uniqueness.

create multiple index records

You can create multiple index records from one source segment of an index.

store duplicate data

You can include up to five duplicate data fields that you obtained from the primary DEDB segment in the index.

maintain indexes

BMC AMI Fast Path Indexer for IMS lets you populate the index only with data that meets specific criteria. For example, you can ignore records from the primary DEDB that contain blanks or zeros by using the NULLVAL keyword or the sparse indexing exit (secondary index database maintenance exit) routine.

use an inverted hierarchy

BMC AMI Fast Path Indexer for IMS supports an inversion of hierarchy up to the root segment. To use an alternate processing sequence, you must specify the PROCSEQ keyword.
