OpenEdge Data Management: DataServer for Microsoft SQL Server

Enabling ABL to SQL Correlation in Logging
Connecting a schema holder
The Enhanced Logger allows ABL to SQL correlation so that you can compare ABL
database requests with SQL directives that are executed on the server.
In the DataServer log file, ABL to SQL correlation includes information from the client
context, the ABL module and line number, along with the server context SQL that was
generated based on the ABL code and run against the foreign data source. The
correlation is enabled using the -Dsrv PRGRS_LOG_ABL,n switch where n ranges from
0 to 2, as demonstrated in the following example:
-Dsrv logentrytypes,SQL:2,PRGRS_LOG_ABL,2
For a DataServer broker instance, the SQL log entry type can be set by using the -Dsrv
logentrytypes,SQL switch in the ‘srvrStartupParam’ property under the
UBroker.MS section in OpenEdge Management/OpenEdge Explorer or
ubroker.properties files or using the parameter file .pf.
Table 41 describes the PRGRS_LOG_ABL connect option values:
Table 41: PRGRS_LOG_ABL connect option values
Option Value Description
0 Disables the ABL to SQL correlation feature. No correlation
information will be logged.
1 Enables the ABL to SQL correlation feature for SQL-related log
entry types. Every SQL request derived from the log entry type
output is preceded by ABL filename and line number which can
be correlated to a compiled listings file.
2 Enables a superset of value 1 which, along with correlation
information, includes visual delimiters marking the start and
end of each ABL file module.
Note: The SQL log entry type is specifically designed to output SQL-related logging
information and therefore would be used most commonly in conjunction with
the PRGRS_LOG_ABL -Dsrv switch. However, the PRGRS_LOG_ABL switch can
be enabled to acquire module and line number information with any log entry
type that writes SQL request information to the log.
The ABL to SQL correlation is logged in the dataserv.lg file where the log entries will
contain the ABL module and the line number where the ABL procedure started. It will
also contain information about the SQL query executed on the foreign data source and
the visual delimiters.
