Defining User Migration Options
An MPE V/E file has different disk space requirements depending upon
which of the following MPE/iX execution modes you plan to migrate it to:
* Compatibility Mode (CM)
* Native Mode (NM)
* Object code Translated Mode (TM)
For each file in the MPTDB database, MPT estimates the amount of disk
space required by the file for each of these modes. The MPTREPT program
includes this information in its migration planning reports. In
addition, when MPT calculates final disk space considerations for all
files included in the report, you select one of the modes for the
calculations. The final disk space considerations are included in a
general information summary automatically printed each time MPTREPT is
run. To determine the chosen mode for migration, the MPTREPT program
checks a special parameter file associated with the formal designator
MPTOPTNS. If the file is not specified in MPTOPTNS, MPTREPT selects CM as
the chosen migration mode.
You can encode user migration options for selected filesets into the
special parameter file where the MPTREPT program can access it. The
final disk space will be calculated using your chosen mode for each file
(instead of the default, CM). A parameter file, MPTOPTNS.MPT.TELESUP, is
supplied by MPT and already contains a set of migration options you would
probably use.
To set or change the user migration options, use the text editor of your
choice to modify MPTOPTNS.MPT.TELESUP or create your own parameter file
and use a file equation to equate your file to the formal designator
(MPTOPTNS) expected by the MPTREPT program. This parameter file contains
key words to identify the files to select and some action for those
files.
You can specify the files to select for an action in a variety of ways.
The following key words can be used alone or in combination to select
files:
FNAME= Specify the fully qualified file name. (MPE
wildcard characters are allowed.)
FCODE= Specify the numeric MPE file code for the files.
CLASS= Specify the mnemonic file classification (for
example, PROGRAM).
LANGUAGE= Specify the programming language chosen by MPT for
the file.
In addition, you can specify the file size (in sectors) for files which
you are adding to the report, but which are not located on the system
being analyzed. Only the NM file size is required, but you can supply
the others if you desire to see them on the detail level reports. Key
words to supply file sizes are:
CM= Specify the CM file size in sectors.
NM= Specify the NM file size in sectors.
TM= Specify the Translated Mode file size in sectors.
OT= Specify the other mode file size in sectors.
Actions can be one of the following:
CM Migrate these files into CM. (This is the default.)
NM Migrate these files into NM.
TM Migrate these files into object code translation
mode.
OT Migrate these files into "other" (as yet
undefined).
Delete Do NOT migrate these files to the MPE/iX system.
Add Add a file to the MPE/iX system which does not
already exist on the MPE V/E system.
NOTE To ADD a file, you must also supply the file name and NM file size
with the FNAME= and NM= key words (see below).
The MPTOPTNS file could look like this:
FCODE=1029;LANGUAGE=SPL;ACTION=TM
CLASS=PROGRAM;LANGUAGE=COBOL;ACTION=CM
CLASS=IMAGE;ACTION=NM;FNAME=@.@.ACCTNG
The sample MPTOPTNS file above is interpreted in the following manner:
* Use translation mode disk space estimates when calculating final
disk space considerations for SPL program files included in the
report.
* Use CM disk space estimates when calculating final disk space
considerations for COBOL program files included in the report.
* Use NM disk space estimates when calculating final disk space
considerations for IMAGE files located in the account ACCTNG
included in the report.
