MUTNWARN, Database file xxxx has 0xaaa more transactions to go before reaching the transaction number limit (0xbbbb). Renew database with MUPIP INTEG TN_RESET.
MUPIP Warning: This indicates that MUPIP INTEG detected that the transaction numbers in the named database are approaching the maximum number as specified by the Maximum TN Warn field in the database file header. The actual maximum TN is less than this theoretical limit. DSE DUMP FILEHEADER shows what the limit is. The actual limit reflects some overhead used, for example, during a TN_RESET operation.
Action: Use MUPIP INTEG with the qualifier TN_RESET to reset the transaction numbers in the database. If the database is in the V4 format, consider converting it to the V5 format.
