These environment variables that set run-time options, which are used as the xfODBC driver accesses the database. Unless otherwise noted, the xfODBC Database Administrator (DBA) and dbcreate do not use these environment variables, and they do not affect the way the system catalog is generated. For information on environment variables that affect the system catalog, see System catalog generation variables.

Environment variable |
Purpose |
For more information… |
|
GENESIS_HOME |
Specifies the location of the connect file. (DBA and dbcreate also use this environment variable.) |
|
|
GENESIS_INITSQL |
Specifies a file that contains predefined SQL statements. |
|
|
GENESIS_MSG_FILE |
Sets the name and location of the error message file. (DBA and dbcreate also use this environment variable.) |
|
|
SDMS_AUDIT |
(Unix) Specifies the path and filename of the Synergy DBMS log file on Unix. (Use SDMS_AUDIT_SRV for Windows.) |
|
|
SDMS_AUDIT_FULL |
Turns on Synergy DBMS logging. |
|
|
SDMS_AUDIT_MODE |
Instructs xfODBC to log I/O control modes for each file operation. |
|
|
SDMS_AUDIT_SRV |
(Windows and Unix) Specifies the path and filename for generated auditing files for file operations on a server or a threaded Windows program. |
|
|
SDMS2_FULL |
Records additional ODBC calls to the Synergy database. Unlike SDMS2_LOG, this environment variable can be set in Windows, Unix, and OpenVMS environments. |
|
|
SDMS2_LOG |
(OpenVMS) Specifies the path and filename of the Synergy DBMS log file. |
|
|
SODBC_INIFIL |
Specifies the path and filename of the environment setup file. |
Specifying the location of the environment setup file (SODBC_INIFIL) |
|
SODBC_MCBA |
Instructs xfODBC to skip records that contain MCBA deleted-record characters (]]]]). |
|
|
SYNBASEDATE |
Sets the base date for conversion of date fields with the JJJJJJ format. The default date is 1752-09-14 (14 September 1752). Once you’ve modified data in the database, do not change the SYNBASEDATE value or the database will be corrupted. Each date is stored as the difference between the entered date and the SYNBASEDATE value. Changing this value changes the way dates are stored and read. |
|
|
SYNCENTURY |
Specifies the cutoff year for a sliding window mechanism that converts two-digit years to four-digit years. SYNCENTURY determines the cutoff year and affects only input dates with two-digit year formats (YYMMDD, YYJJJ, etc.). |
|
|
TRIM_HOME |
Specifies the location of the lib directory that contains trim.ini (Unix only) and trim.msg files used for system catalog caching. |
|
|
VORTEX_API_LOGFILE |
Turns on logging and specifies the path and filename of a log file used to log statements issued to the database by the xfODBC driver. |
|
|
VORTEX_API_LOGOPTS |
Specifies options for the file produced by VORTEX_API_LOGFILE. |
|
|
VORTEX_HOST_LOGFILE |
Turns on logging and specifies the path and filename of the logfile used to log statements passed to SQL OpenNet from the xfODBC driver. |
|
|
VORTEX_HOST_LOGOPTS |
Specifies options for the file produced by VORTEX_HOST_LOGFILE. |
|
|
VORTEX_HOST_SYSLOG |
Instructs the SQL OpenNet server to generate messages for the event log (Windows), syslog (Unix), or the operator console (OpenVMS) when an attempt to connect to an SQL OpenNet server causes fatal errors. |
|
|
VORTEX_ODBC_CHAR |
Determines how xfODBC describes strings (SQL_VARCHAR or SQL_CHAR). |
|
|
VORTEX_ODBC_DATETIME |
Determines how datetime columns are retrieved. |
Changing the default data type returned for datetime columns |
|
VORTEX_ODBC_TIME |
Determines how time columns are described. |
Changing the default data type for returned time columns and Time columns and ADO.NET |
|
VORTEX_SHM_BASE |
Sets the base address for system catalog caching. |
|
|
VORTEX_SHM_FILE |
Specifies the location and name of synodbccache.dat, a file used for system catalog caching. |
