Generic Files and a Dedicated Query Processor
In most cases, a generic output file is an unstructured file. When Enform Plus opens an
unstructured file to write records, the records are written starting at the beginning of the
file and the existing records are overwritten.
Generic Files and a Dedicated Query Processor
Generic files QUERY-WORK-AREA, QUERY-SORT-AREA, QUERY-QPSTATISTICS,
and QUERY-QPSTATUS-MESSAGES can be specified for a dedicated query processor
by using either the Enform Plus ?ASSIGN command (see page 6-3) or the TACL
ASSIGN command (see Logical File Assignments on page 2-4). The ASSIGN
command is passed through the Enform Plus compiler/report writer to the query
processor for each LIST or FIND statement until the ASSIGN is cleared.
The query processor opens both QUERY-QPSTATISTICS and QUERY-QPSTATUS-
MESSAGES for every FIND or LIST request. Generally, statistics and errors for
multiple requests to a dedicated query processor cannot be collected in a disc file
because the results are written over each other. However, by assigning the generic file to
a process, the statistics and errors can be collected for multiple requests to a dedicated
query processor.
QUERY-SORT-AREA The location where all temporary files are built by the
SORT process while processing a FIND or LIST
statement during an Enform Plus session. The
QUERY-SORT-AREA file name can be a volume
name or an explicit file name.
QUERY-QPSTATISTICS The statistics produced for every FIND or LIST
statement that is successfully processed by the query
processor during an Enform Plus session (regardless of
the setting of @STATS). Each set of statistics is
identified by a line containing the requestor's PID and
the beginning and ending times of the query execution.
If @STATS is set to ON, statistics are also reported to
the QUERY-STATISTICS file.
The output is produced in ASCII. For each query
processed, the output consists of (72 * (the number of
record-types in the query + 3)). For display purposes,
each output record is 72 characters in length.
QUERY-QPSTATUS-MESSAGES All error messages produced by the query processor or
SORT during the processing of a FIND or LIST
statement during an Enform Plus session. To identify
the query in error, each message is preceded by the
requestor's PID and the time of the error.
Errors are also reported to the QUERY-STATUS-
MESSAGES file.
The output is produced in ASCII with a record length
of 132 bytes.
