through several syslogd error messages output to the monitor or a failed attempt at restarting the
failed conversion program. Should DB2 be placed in an inconsistent state, the tablespace will likely
have to be dropped and recreated along with the table being converted. Then the database will need to
be recycled (using db2stop and db2start).
Note that the long running conversion programs are started from a script that will call a C program to
read metadata from SFS, convert the data, and write the data to a named pipe. The script then issues
the DB2 load command which reads from the named pipe. To ensure correctness of the metadata
converted, the number of records submitted to the load from the C program should equal the number
of committed rows by the load utility. Output for a successful conversion will look like the following:
Running lr_db_convert_nsobject utility...
Converting SFS file

Number of rows read = 103749
Number of rows skipped = 0
Number of rows loaded = 103749
Number of rows rejected = 0
Number of rows deleted = 0
Number of rows committed = 103749
Notice that the number of rows committed by the load (103749) is equal to the C program's number
of rows submitted to the load (103749). If the numbers do not agree or any deleted, skipped or
rejected rows are encountered, the conversion program has not converted the metadata correctly. In
this case, contact your HPSS customer support representative.
In the case that you have already run a long running conversion and it failed, follow restart
procedures in Section 6.3.13.5:
Restarting the Long Running Utilities on page 207. The output upon
restart should look like the following:
Re-running lr_db_convert_nsobject utility...
