Creating the Migration Planning Tool Database
You must create the MPTDB database before you can generate MPT
migration planning reports. Two MPT programs, MPT.MPT.TELESUP and
MPTRTM.MPT.TELESUP, are used to create the database and load it with data
collected from files located on the system being analyzed. Normally, you
need only create the database once for each system being analyzed. If
the database already exists from a previous run, new information is
appended.
It is recommended that you create the MPTDB database using the MPTJOB
.MPT.TELESUP job stream file supplied by the MPT/3000 product. (Refer to
"Running MPT in Batch Mode" for details.) This batch job will also
generate a set of migration planning reports and an installed product
report.
NOTE You should run the RTM before running MPT. Migration event data
placed by RTM in system log files can be collected by MPT into the
MPTDB database and accessed whenever MPT generates migration
reports. MPT can be run without benefit from RTM but the quality
of the reports is greatly improved if this data is available.
To create the MPTDB database, follow the steps outlined below. Some of
the steps are not required, but all must be considered:.
1. Run RTM: For details on using RTM, refer to Appendix C, "Using the
Run Time Monitor".
2. Size the Database: In order to properly size the data sets in
this database, MPT must know approximately how many disk files the
database will hold. If the database is built too small, MPT or
successive programs will abort with database errors. To avoid
errors, size the database slightly larger than the estimated need.
MPT determines the maximum allowable size of the database by
checking the MAXFILES Job Control Word (JCW). If the default value
for MAXFILES (30,000) is unsuitable for your needs, you will have
to set it to your selected value prior to running MPT. For
example, to create a database large enough to hold 50,000 files
you would enter the following command prior to running MPT:
: SETJCW MAXFILES=50000
3. Create and Load the Database: During this step, it is recommended
that all other users be off the system, as the system will be
extremely busy, and disk files should not be accessed by other
programs. You must have System Manager (SM) capability prior to
running the MPT program.
_________________________________________________________________
NOTE Schedule adequate time to run the MPT program. The MPT
program may take anywhere from thirty minutes to eight hours
to create and load the MPTDB database, depending upon the
number and types of disk files on your system.
_________________________________________________________________
Run the MPT.MPT.TELESUP program to create and load the MPTDB
database used by MPT. Normally, MPT scans all disk files on the
system including those on mounted and enabled private volumes.
You can optionally limit the number of files scanned by MPT by
using the INFO= parameter of the :RUN command to specify the MPE
fileset you want scanned.
The following example executes the MPT program, specifying that
only files in the ACCTING account are to be scanned:
: RUN MPT.MPT.TELESUP;INFO="@.@.ACCTING"
The MPT program creates a database (MPTDB) to contain the results
of the analysis. Information regarding each file scanned is
logged in the MPTDB database. The information logged can vary
depending on the type of file. It includes some classification to
identify the type of the file. The disk capacity requirement for
the file is projected for each of the following MPE/iX modes: CM,
NM, and Translated Mode
As each disk file is opened and scanned, program files, SL files,
job stream files, and UDC files are examined more closely to see
if they contain any migration events. If so, these events will
also be logged in the database.
4. Load RTM Events: Run the MPTRTM program by entering:
:RUN MPTRTM.MPT.TELESUP
At the prompt LOG FILES ON TAPE OR DISC?, you must respond with
DISC.
At the prompt LOG FILES TO BE SCANNED?, respond with either of the
following:
ALL MPTRTM scans through all log files found on
the system.
m,n MPTRTM scans through the system log files
numbered m to n.
When RTM events are found recorded in the selected log files, they
are entered into the MPTDB database.
This concludes the data collection portion of MPT. You now use the
MPTREPT program to generate migration planning reports.
