application. If TimesTen cannot locate a user DSN file, the system DSN
file located in
/var/TimesTen/sys.odbc.ini will be used. Also, see
“Defining data sources for the demo applications” on page 83 for more
information on the .odbc.ini file. For non-root installations, TimesTen
also looks for the sys.odbc.ini file under install_dir /info.
SYSODBCINI environment variable
TimesTen applications use the sys. odbc.ini file to define system data
sources and their data store attributes. (For a description of data store
attributes, see
Chapter 1, “Data Store Attributes” in the Oracle
TimesTen In-Memory Database API Reference Guide .) A system data
source can be used by any user on the machine. On Windows, system
DSNs are defined from the System DSN tab of the ODBC Data Source
Administrator. On UNIX, system DSNs are defined in the file
/var/
TimesTen/sys.odbc.ini . To override the name and location of this file
at run-time, set the $SYSODBCINI environment variable to the pathname
of a sys.odbc.ini file before launching the TimesTen application.
If TimesTen cannot locate a user DSN file, the system DSN file located
in
/var/TimesTen/sys.odbc.ini will be used. For non-root
installations, TimesTen also looks for the sys.odbc.ini file under
install_dir /info .
Also, see “Defining data sources for the demo applications” on page 83
for more information on the .odbc.ini file.
SYSTTCONNECTINI environment variable
TimesTen client applications use the sys.ttconnect.ini file to define
logical server names. For a description of logical server names, see
Chapter 2, “Working with the TimesTen Client and Server” in the
Oracle TimesTen In-Memory Database Operations Guide . By default on
UNIX platforms, TimesTen looks in /var/TimesTen/
sys.ttconnect.ini . To override the name and location of this file at
run-time, set the SYSTTCONNECTINI environment variable before
launching the TimesTen Client application.
For non-root installations, TimesTen also looks for the
sys.ttconnect.ini file under install_dir /info .
On Windows systems, logical server names can be configured using the
ODBC Data Source Administrator.
