FABADA1 SNAPPIT DD data set

The SNAPPIT DD data set contains the CI Map/CI Dump report produced by the FABADA1 program.

Format

The data set contains 133-byte fixed-length records, and block size (if coded in your JCL statement) must be a multiple of 133. You should code your DD statement as follows:

//SNAPPIT DD SYSOUT=A

CI Map/CI Dump report

This report provides the CI map/CI dump as a part of the processing. With this report, you can get all the CIs necessary to analyze any broken database without having to perform another run to obtain such information.

Purpose

The CI Map/CI Dump report is used to analyze DEDB area CIs in order to determine the best way to repair them. The report provides the following information:

CI map that is a list of CI header, all the segments, free space elements, scrap bytes, unknown area, and CI trailer that the DEDB Pointer Checker found in the CI.
CI dump that is logically formatted based on the CI map.

The following figure shows the CI map section of the CI Map/CI Dump report.

The following are the descriptions for this figure.

STORAGE

The memory address of the first byte in that line of the CI map.

TYPE

The one of the following entries in database CI:

segment-name

The segment that includes prefix and data.

FSE

The free space element.

SHORT-FS

Scraps (that is, free space less than 4 bytes).

UNKNOWN

Area that the DEDB Pointer Checker could not identify as segment, FSE, or scrap bytes area. If the CI is in SDEP part, segments and unused area are treated as unknown area.

HEADER

The first 4 or 8 bytes of the CI that contains the following items:

FSEAP 2 bytes: Offset to the first Free Space Element (FSE). These two bytes are unused if the CI is in the SDEP part as it does not contain FSEs.
CI 2 bytes: Describe the use of this CI and the meaning of the four next bytes. DSECT DBFDBLK in the distributed IMS libraries provides a detailed mapping of these fields.
RAP 4 bytes: Root Anchor Point if this CI belongs to the base section of the root addressable part. All root segments randomizing to this CI are chained off this RAP in ascending key sequence. There is only one RAP per CI.
Note: In the dependent and independent overflow parts, these 4 bytes are used by Fast Path for control information. There is no RAP in SDEP CIs.

TRAILER

The last 13 bytes of the CI that contains following items:

CUSN 2 bytes: CI update sequence number (CUSN) maintained in each CI except in the SDEP part.
RBA 4 bytes: Relative byte address (RBA) of this CI.
RDF 3 bytes: Record definition field (VSAM control information).
CIDF 4 bytes: CI definition field (VSAM control information).

RBA

The relative byte address of the area defined by this CI map entry.

ADDRESS

The address in memory.

FLAGS

Always contains zero.

SC

The segment code. The value is zero if TYPE contains the segment name.

COUNTERS

Always contains zero.

LENGTH

The length of the area defined by this CI map entry.

ROOT#

Always contains zero.
