The reports fields are as follows:
- DBNAME
- The name of the DBD as coded on the NAME keyword of the DBD macro
- DB#
- The database number (in hexadecimal) that identifies the database processed throughout the HD Pointer Checker run
- PID
- The partition ID (in decimal) that identifies the partition containing the segment that contains the pointer
- PARTNAME
- The name of the partition
- DSG#
- The data set group number (in hexadecimal) that identifies the database processed throughout the HD Pointer Checker run
- DBLG#
- The database logical group number which indicates that physical databases with the same database logical group number are logically related to each other
- DDNAME
- The ddname as coded on the DD1 keyword or OVFLW keyword of the DATASET macro in the DBD
- DB-ORGANIZATION
- The type of database organization (HISAM, HIDAM, HDAM, INDEX, LOGICAL, and so on)
- C-DATE
- The date when the database data set was actually created. If the specified data set is an image copy database data set, this is the date when the image copy database data set was created.
- ACCM
- The type of access method
- BLKSZ
- The block size
- D-DATE
- The date when the SCAN process was performed if the specified data set is a real database data set or a Fast Recovery image copy data set. If the specified data set is an image copy database data set, this is the date when the image copy database data set was created.
- D-TIME
- The time when the SCAN process was performed if the specified data set is a real database data set. If the specified data set is an image copy database data set, this is the time when the image copy database data set was created.
- LRECL
- The logical record length of the database data set
- DBTYPE
- Indicates whether the database data set is a real database or
an image copy data set. If an image copy data set that has been created
more than five days older than the date when the SCAN process was
done, the indicator
"*"follows the image copy indicator "IMGCPY". - DEVICE
- The device type of a real database or the type of the image copy database data set (that is, TAPE or DASD) if an image copy database data set is used
- CHK-DATE
- The date when the CHECK process was done
- CHK-TIME
- The time when the CHECK process was done
- %SEGMS IN OFLW
- The percentage of segments in the overflow (ESDS or OSAM) part of the data set group
- DATA-SET SIZE
- The data set size that is used by IMS
- CYL’S
- The data set size in cylinders. This is the round up value of the number of scanned Cls/blocks divided by the number of physical blocks per cylinder for the particular DASD.
- BYTES
- The data set size in bytes. The number of scanned Cls/blocks multiplied by the length of the Cl/block.
- F-SPACE
- The reusable free space in the database as indicated by FSEs that
can hold the longest segment in the data set group
- %
- The percentage of the reusable free space in the data set that is the percentage of F-SPACE in bytes against DATA-SET SIZE in bytes
- BYTES
- The F-SPACE in bytes (See Figure 1)
- DETECTED ERRORS
- The number of errors detected throughout the HD Pointer Checker run is
shown by the following fields:
- TOTAL
- The total number of errors which include unknown areas (that is, T2 records)
- UNKNOWN
- The total number of unknown areas (T2 records)
When DETECTED ERRORS TOTAL and UNKNOWN overflow, values 9999 are shown with an asterisk in the fields.
