Messages describing errors or inconsistencies are generated during
EXAMINE processing as that condition is detected. The detection of
an error condition can result in the generation of many messages.
There are five distinct types of EXAMINE error messages:
- Status and Statistical Messages. This type
of message tells you the status of the EXAMINE operation, such as
the beginning and completion of each test. It provides general statistical
data, such as the number of data records, the percentage of free space
in data control intervals (CIs), and the number of deleted CIs. The
four status messages are IDC01700I, IDC01701I, IDC01709I, and IDC01724I.
The five statistical messages are IDC01708I, IDC01710I, IDC01711I,
IDC01712I, and IDC01722I.
- Supportive (Informational) Messages. Supportive
messages (all remaining IDC0-type messages) issued by EXAMINE clarify
individual data set structural errors and provide additional information
pertinent to an error.
- Individual Data Set Structural Error Messages. The
identification of an error is always reported by an individual data
set structural error (IDC1-type) message that can be immediately followed
by one or more supportive messages.
- Summary Error Messages. One or more summary
error (IDC2-type) messages are generated at the completion of either
INDEXTEST or DATATEST to categorize all individual data set structural
error (IDC1-type) messages displayed during the examination. The summary
error message represents the final analysis of the errors found, and
the user should follow the course of recovery action as prescribed
by the documentation.
- Function-Not-Performed Messages. Function-not-performed
messages (all of the IDC3-type messages) indicate that the function
you requested cannot be successfully performed by EXAMINE. In each
case, the test operation terminates before the function completes.
Function-not-performed
messages are issued for a variety of reasons, some of that follows:
- A nonvalid request (such as an attempt to examine an entry-sequenced
data set (ESDS))
- A physical I/O error in a data set
- A system condition (such as insufficient storage)
- A system error (such as an OBTAIN DSCB failed)
- An error found during INDEXTEST (see Skipping DATATEST on Major INDEXTEST Errors).
