Report field description

For the description of all the fields in this report, see Space Analysis by Data Set report.

The following messages are included in the report:

***** LARGER THAN 4 GIGABYTES *****
The total space of the data set is equal to or larger than 4 gigabytes for any of the following data sets:
  • VSAM data set without the extended addressability attribute
  • If the data set is a HALDB data set, VSAM linear data set with NOOSAM8G specified in the RECON data sets
  • Non-VSAM data set whose block size is odd

Each field of ALLOC, %FSP, %NRUS, TOTBLK, and %USED is calculated by the total space in the data set, which is treated as X’FFFFFFFF’ (4 gigabytes - 1 byte).

***** LARGER THAN 8 GIGABYTES *****
The total space of the data set is equal to or larger than 8 gigabytes. Each field on ALLOC, %FSP, %NRUS, TOTBLK, and %USED is calculated by the total space in the data set, which is treated as X’1FFFFFFFE’ (8 gigabytes - 2 bytes).
***** LAST HDPC RUN OLDER THANcc DAYS *****
The most recent HD Pointer Checker run with HISTORY=YES option for the database data set was done earlier than the warning threshold specified in columns 70-71 of the first control statement for the database data set.

An asterisk (*) is shown after %FSP, %NRUS, and REORGDATE value, showing that these values are not accurate because the HD Pointer Checker run with the HISTORY=YES option is obsolete (older than the specified limit). An asterisk (*) is also shown after the date on the HDPCDATE field showing that the HD Pointer Checker run date is older than the specified limit.

***** THE PERCENTAGE OF FREE SPACE IS LESS THAN OR EQUAL TO bbb % *****
The percentage of free space in the data set is equal to or less than the warning threshold value specified in columns 66-68 of the first control statement for the data set.
***** THE NUMBER OF EXTENTS IS MORE THAN OR EQUAL TO aa *****
The number of extents of the data set is equal to or greater than the warning threshold value specified in columns 64-65 of the first control statement for the data set.
***** NONE *****
No exceptional conditions were detected for any of the database data sets and/or OS data sets processed.
***** THE NUMBER OF AVAILABLE EXTENTS IS LESS THAN OR EQUAL TO ppp (VOLUME LIMIT) ***** or
***** THE NUMBER OF AVAILABLE EXTENTS IS LESS THAN OR EQUAL TO ppp (DATASET LIMIT) *****
The number of available extents in the data set is equal to or less than the warning threshold value specified in columns 10 and 11 of the second control statement for the data set. However, this message is not printed for the following types of data sets, as the number of available extents (AEXT) is always zero:
  • VSAM data set whose secondary allocation is zero and for which only one volume is defined.
  • Non-VSAM data set whose secondary allocation is zero.
***** CA SPLITS %xxx WHICH REACHES OR EXCEEDS ttt %. TOTAL CA COUNT IS yyyyyyyyy *****
The ratio of the number of control area (CA) splits compared to the total number of CAs is equal to or more than the warning threshold value. 
xxx = (the number of CA splits that have occurred for the data set) / yyyyyyyyy * 100 (%)

When the number of CA splits that have occurred for the data set is greater than the total number of CAs, xxx is shown as 100 (%).

ttt is the warning threshold value that is specified in columns 21-23 of the second control statement for the data set.

***** CI SPLITS %xxx WHICH REACHES OR EXCEEDS uuu %. TOTAL CI COUNT IS yyyyyyyyy *****
The ratio of the number of control interval (CI) splits compared to the number of CIs is equal to or more than the warning threshold value. 
xxx = (the number of CI splits that have occurred for the data set) / yyyyyyyyy * 100 (%)
yyyyyyyyy is the number of CIs up to the high-used RBA.

When the number of CI splits that have occurred for the data set is greater than the total number of CIs, xxx is shown as 100 (%).

uuu is the warning threshold value that is specified in columns 25-27 of the second control statement for the data set.

***** USING LAST EXTENT (VOLUME LIMIT) ***** or
***** USING LAST EXTENT (DATASET LIMIT) *****
The last extent has been used. To display this message, specify Y in column 13 of the second control statement for the data set; to suppress it, specify * there. However, this message is not printed for the following types of data sets, as the number of available extents (AEXT) is always zero:
  • VSAM data set whose secondary allocation is zero and to which only one volume is defined.
  • Non-VSAM data set whose secondary allocation is zero.
***** THE PERCENTAGE OF USED SPACE IS MORE THAN OR EQUAL TO rrr % *****
The percentage of space used on the volume reached or exceeded the warning threshold value specified in columns 15-17 of the second control statement for the data set.
***** LAST REORGANIZATION DATE IS MORE THAN vvv DAYS BEFORE *****
The most recent reorganization date of the database data set is earlier than the warning threshold specified in columns 29-31 of the second control statement for the database data set.
***** NO LAST REORGANIZATION DATE *****
The warning threshold value for the reorganization data was specified in columns 29-31 of the second control statement, but the most recent reorganization data does not exist in the HISTORY data set.
***** NO SPACE AVAILABLE TO EXTEND THE DATA SET *****
Although the number of extents available is greater than zero, no contiguous space is available to extend the data set.
Note: VSAM extent consolidation is not taken into consideration. Even if this message appears when processing a VSAM data set, extending the data set might be possible. For information about VSAM extent consolidation, see z/OS® DFSMS Using Data Sets.
This threshold value is controlled in column 19 of the second control statement for the data set. However, this message is not printed for the following types of data sets, as the number of available extents (AEXT) is always zero:
  • VSAM data set whose secondary allocation is zero and for which only one volume is defined.
  • Non-VSAM data set whose secondary allocation is zero.
***** NEXT VOLUME NOT YET SELECTED BY SMS *****
The warning threshold value for the last available space was specified in column 19 of the second control statement, but the available space cannot be calculated because the volume cannot be identified.

This message is issued when no space exists on the current volume and the next volume names is '*'—that is, when the volume name has not been selected by DFSMS/MVS™.

***** THE PERCENTAGE OF DATA SET SIZE TO MAX SIZE IS xxx.x %. IT REACHES OR EXCEEDS yyy % *****
The percentage xxx.x—that is, the ratio of the space that is used in the data set to the maximum size of the IMS database data set—is equal to or more than the warning threshold value yyy that is specified in column 33-35 of the second control statement for the data set.
***** DATA SET SIZE REACHES OR EXCEEDS xxxx MEGABYTES ***** or
***** DATA SET SIZE REACHES OR EXCEEDS xxxx GIGABYTES***** or
***** DATA SET SIZE REACHES OR EXCEEDS xxxx TERABYTES *****
The data set size is equal to or more than the warning threshold value xxxx MB, GB, or TB. The warning threshold value is specified in columns 37-40 and column 41 of the second control statement for the data set.
