Word Mnemonic [symbolic command] Description
---- -------- -------------------------------
KTMTT... Mnemonic bank address relative to start of
user data.
1 I _SDB_ENB [$enable_database/$disable_database]
SDB interface flag: = 0 disabled, = 1 enabled.
If disabled, the database will not be searched for
missing titles banks.
Note: currently this also initialises SDB. See
item 9 of the release notes: since_2_08.doc
2 I _TITLES_CHECK [$enable_titles_check]
Titles bank checking flag: = 0 disabled, = 1 enabled.
If enabled, at start of termination MTT will compare
banks loaded via titles files against their database
counterparts. N.B. Identical banks may have real data
that is not bit identical if bank was originally loaded
into the database from another platform. This will show
as a "Reals within tol." comparison result.
Setting flag =2 will print out the words that fail comparison.
3 I _MAX_RESYNC [$max_titles_resync]
Maximum number of resynchronisations in both directions.
This cut is designed to kill SNOMAN in production mode
if processing bad data with many forward and backward
time jumps that results in many database reloads as the
job can takes days to complete. The cut is only
effective if jumping in BOTH directions, so a DST of
golden events drawn from many runs won't fail so long
as they are processed in run order (ascending or
decending).
Set cut to 0 to disable it.
4 I _SDB_MF_TEST [$sdb_multi_file_test]
SDB multi-file testing: = 0 disabled, = 1 enabled.
If enabled, at start of termination MTT will run
a short sequence of tests trying to read titles banks
from each of the physical files in all multi-file
database files.
