 tables whose name starts with the prefix "QCM" exist in the database,

During conversions, the data from the tables for conversion

temporarily stored in tables with the name "QCM<table_name>".
These QCM tables are deleted for the corresponding table before each
upgrade.

As of Release 3.0D, the QCM tables will be automatically deleted after a sucessfully completed conversion.ITPUB个人空间ntcs/
W!df`h
Prior to Release 3.0D, you can delete these tables with DB means or the database utility.
UD#J%|"/rz[�r13316Be
sure to check, however, before deleting, whether the table is
consistent. The database utility should not display a restart log or a
conversion procedure termination. In addition, check whether the data
of the original table is legible (e.g. by using transaction SE16). If
application programs do not run correctly which use the affected
original table, do not delete the QCM table yet.
[ZP5JyyK-r13316Once
you are certain that the QCM table is ready for deletion, you can
delete on the database using 'sqlplus' or 'sqldba' (ORACLE), 'dbaccess'
(INFORMIX), 'xutil' (ADABAS), 'ISQL/W' or 'Enterprise' under
'Manager->Tools-> Query Tool' (SQL Server in each case).

of Release 3.0D, you can also use the database utility for deleting QCM
tables. To do this, start transaction SE14 and select
'Extras->Invalid temp. table' in the menu bar. This displays all the
QCM tables that can be deleted. Simply mark them and delete with the
push of a button. QCM tables in which the conversion is not yet
complete are not listed.
