1 /CHECK
Checks the integrity of the file and generates a report of any
errors in its structure. The report produced by the /CHECK
qualifier includes a list of any errors and a summary of the
file's structure. If you do not specify an output file, the
report is written to the current SYS$OUTPUT device, which is
generally your terminal. You can use wildcards and multiple file
specifications. If you specify /NOOUTPUT, you only get a message
indicating whether the file has errors.
The check function is active by default when you use the ANALYZE
/RMS_FILE command without any qualifiers. The /CHECK qualifier
is not compatible with the /FDL qualifier, the /INTERACTIVE
qualifier, the /STATISTICS qualifier, or the /SUMMARY qualifier.
If /CHECK is used with any of the other qualifiers, /FDL takes
precedence, next is /INTERACTIVE, then /STATISTICS, and lastly
/SUMMARY.
2 /FDL
Generates an FDL file describing the RMS data file being
analyzed. By default, the /FDL qualifier creates a file with the
file type .FDL and the same file name as the input data file. To
assign a different type or name to the FDL file, use the /OUTPUT
qualifier. If the data file is corrupted, the FDL file contains
the Analyze/RMS_File utility error messages.
For indexed files, the FDL file contains special analysis
sections you can use with the EDIT/FDL Optimize script to make
better design decisions when you reorganize the file.
You cannot use wildcards or multiple file specifications with
the /FDL qualifier. The /FDL qualifier is not compatible with the
/CHECK qualifier, the /INTERACTIVE qualifier, the /STATISTICS
qualifier, the /SUMMARY qualifier, or the /UPDATE_HEADER
qualifier. The /FDL qualifier takes precedence over all other
qualifiers.
3 /INTERACTIVE
Begins an interactive examination of the file's structure. You
cannot use wildcards or multiple file specifications. For help
with the interactive commands, enter the HELP command at the
ANALYZE> prompt.
Do not use this qualifier with the /CHECK, /FDL, /STATISTICS,
/SUMMARY, or /UPDATE_HEADER qualifiers. If used with the /FDL
qualifier, the /FDL takes precedence. All other qualifiers are
ignored when used with /INTERACTIVE.
4 /OUTPUT
/OUTPUT=filesspec
/NOOUTPUT
Identifies the destination file for the results of the analysis.
The /NOOUTPUT qualifier specifies that no output file is to be
created. In all cases, the Analyze/RMS_File utility displays a
message indicating whether the data file has errors.
/CHECK Places the integrity report in the output file.
The default file type is .ANL, and the default
file name is ANALYZE. If you omit the output-
filespec parameter, output is written to the
current SYS$OUTPUT device, which is generally
your terminal.
/FDL Places the resulting FDL specification in the
output file. The default file type is .FDL, and
the default file name is that of the input file.
/INTERACTIVE Places a transcript of the interactive session in
the output file. The default file type is .ANL,
and the default file name is ANALYZE. If you omit
the output-filespec parameter, no transcript of
your interactive session is produced.
/RU_JOURNAL Places the recovery-unit journal information in
the output file. The default file type is .ANL,
and the default file name is ANALYZE. If you
omit the output-filespec parameter, output is
written to the current SYS$OUTPUT device, which
is generally your terminal.
/STATISTICS Places the statistics report in the output file.
The default file type is .ANL, and the default
file name is ANALYZE. If you omit the output-
filespec parameter, output is written to the
current SYS$OUTPUT device, which is generally
your terminal.
/SUMMARY Places the summary report in the output file.
The default file type is .ANL, and the default
file name is ANALYZE. If you omit the output-
filespec parameter, output is written to the
current SYS$OUTPUT device, which is generally
your terminal.
5 /RU_JOURNAL
Provides information about recovery-unit journaling where
applicable. You can use the /RU_JOURNAL qualifier on any file,
but it is inoperative on files not marked for recovery-unit
journaling.
This qualifier provides the only way of accessing a file that
would otherwise be inaccessible because of unresolved recovery
units. This situation might be the result of an unavailable
recovery-unit journal file or of unavailable data files that
were included in the recovery unit.
To use the /RU_JOURNAL qualifier, your process must have both
CMEXEC privilege and access to the [SYSJNL] directory (either
SYSPRV privilege or access for UIC [1,4]).
This qualifier is compatible with all of the ANALYZE/RMS_FILE
qualifiers, and you can use it with wildcards and multiple file
specifications.
When you specify the /RU_JOURNAL qualifier, the Analyze/RMS_File
utility provides you with the following data for each active
recovery unit:
o The journal file specification and the journal creation date
o The recovery-unit identification, recovery-unit start time,
cluster system identification number (CSID), and process
identification (PID)
o Information about the files involved in the recovery unit,
including the file specification, the name of the volume where
the file resides, the file identification, the date and time
the file was created, and the current status of the file
o The state of the recovery unit - active, none, started,
committed, or not available (for more information, see the
RMS Journaling for OpenVMS Manual)
o An error statement
6 /STATISTICS
Specifies that a report is to be produced containing statistics
about the file. The /STATISTICS qualifier is used mainly on
indexed files.
By default, if you do not specify an output file with the /OUTPUT
qualifier, the statistics report is written to the current
SYS$OUTPUT device, which is generally your terminal.
The /STATISTICS qualifier is not compatible with the /CHECK
qualifier, the /FDL qualifier, the /INTERACTIVE qualifier, or
the /SUMMARY qualifier. If /STATISTICS is used with any other
qualifiers, /FDL takes precedence, and then /INTERACTIVE. All
other qualifiers are ignored. The /STATISTICS qualifier does an
implicit check.
7 /SUMMARY
Specifies that a summary report is to be produced containing
information about the file's structure and use. The /SUMMARY
qualifier generates a summary report containing information about
the file's structure and use.
If the file has no errors, the output generated from the /SUMMARY
qualifier is identical to that produced by the /CHECK qualifier.
Unlike the /CHECK qualifier, however, the /SUMMARY qualifier does
not check the structure of your file, so output is generated more
quickly.
Do not use this qualifier with the /CHECK qualifier, the /FDL
qualifier, the /INTERACTIVE qualifier, the /STATISTICS qualifier,
or the /UPDATE_HEADER qualifier. If /SUMMARY is used with any
other qualifiers, /FDL takes precedence, next is /INTERACTIVE,
and then /STATISTICS.
8 /UPDATE_HEADER
Attempts to update the following attributes in the header of
the file: longest record length (LRL) and/or file length hint
attribute.
You must use this qualifier in combination with either
/STATISTICS or /CHECK (the default).
This qualifier only applies to sequential file organizations and
is ignored for any other file organization. The /UPDATE_HEADER
qualifier attempts to update the LRL and/or file hint attribute
in the file header if the calculated value(s) differ from the
current value(s) in the file header. The /UPDATE_HEADER qualifier
applies to:
o An LRL request - if the file is sequential and has a record
format other than undefined (UDF).
o A HINT request - if the file is sequential, the record format
is either variable (VAR) or variable with fixed control (VFC),
and the file is located on an ODS-5 disk device.
It is not supported for remote accesses; requests are ignored.
The /UPDATE_HEADER qualifier requires either the STATISTICS or
CHECK (default) functions since calculating new values for the
LRL and/or file length hint presumes that all the records in the
sequential file are processed. It is not compatible with the /FDL
qualifier, the /INTERACTIVE qualifier, or the /SUMMARY qualifier.
Any errors returned by the file system when an attempt to update
the file header fails are ignored. If the update succeeds, the
updated values are displayed at the end of the report.
