Overview and Features
SPR Requirements for Increased Enscribe Limits for the H06.28/J06.17 Release
As of the H06.28 and J06.17 RVUs, format 2 legacy key-sequenced 2 (LKS2) files with increased
limits, format 2 standard queue files with increased limits, and enhanced key-sequenced (EKS) files
with increased limits are introduced. EKS files with increased limits support 17 to 128 partitions
along with larger record, block, and key sizes. LKS2 files with increased limits and format 2
standard queue files with increased limits support larger record, block, and key sizes. When a
distinction is not required between these file types, key-sequenced files is used as a collective term.
To use increased Enscribe limits, the minimum RVUs are H06.28 and J06.17 with the following
specific SPRs. (These SPR requirements could change or be eliminated with subsequent RVUs.)

NOTE: As of the H06.22 and J06.11 RVUs, a new Enscribe file type: enhanced key-sequenced
(EKS) file is introduced and extends the Enscribe partition maximum to 64. An EKS file supports
17 to 64 partitions. The previous Enscribe key-sequenced file type supports 1 to 16 partitions and
is referred to as a legacy key-sequenced (LKS) file in this manual. When a distinction is not required
between these file types, key-sequenced file is used as a collective term.
The Enscribe record manager, supported by the Guardian file system, provides high-level access
to records in a database. Distributed across two or more processors, the Enscribe software helps
ensure data integrity if a processor module, I/O channel, or disk drive fails.
