STOPTIME, ERRORS, STATS, NOSTATS, MODEX, MODE 4, EOF, MDBX, and NOMDBX.

Discussion

The >CONTROL options are described in detail on the next page. If the >CONTROL command

is not used, the following default conditions apply:

STAMP is the database time stamp and must correspond with the one written to

the log ﬁle.

STORE is the DBSTORE ﬂag set in the database root ﬁle.

ABORTS causes transactions which failed to complete due to a program abort to be

recovered.

NOUNEND suppresses the posting of transactions which did not complete or were

aborted prior to a system failure.

ERRORS= during job (batch) execution allows zero errors (DBRECOV terminates), and

during interactive sessions allows 30,000 errors.

MODEX DBRECOV proceeds with exclusive access to the database, using deferred

output (see discussion under DBCONTROL in chapter 5).

NOSTATS if the database is not recovered, no tabulated information will be printed.

STOPTIME= DBRECOV will recover all log records, regardless of the time stamp.

EOF= DBRECOV will recover all log records in the log ﬁle.

MDBX DBRECOV treats multiple database transactions contained in the log ﬁle as

separate transactions.

The >CONTROL command is used to override the default conditions.

If a particular parameter is not speciﬁed within a >CONTROL command, the default

condition remains in effect. Any number of parameters can be named in any order, but if

more than one condition is speciﬁed for one parameter, the last condition entered applies.

For example:

>CONTROL NOSTAMP, STAMP
