Troubleshooting TimesTen Applications and Data Stores 2-7
If the Network Address and Port Number values are correct, the TimesTen Server may
not be running. See "Starting and stopping the Oracle TimesTen Data Manager service
on Windows" in the Oracle TimesTen In-Memory Database Operations Guide for
information about starting the server manually. See "Testing connections" in the Oracle
TimesTen In-Memory Database Operations Guide for more information about identifying
this problem.
On UNIX, specify the TimesTen Server with the TTC_Server connection attribute in
the odbc.ini file on the client machine. If the value specified for TTC_Server is an
actual hostname or IP address, the client tries to connect to the TimesTen Server using
the default port. In TimesTen, the default port is associated with the TimesTen release
number. If the value specified for TTC_Server is a logical ServerName, this logical
ServerName must be defined in the ttconnect.ini file. The ttconnect.ini entry
for this ServerName needs to correctly define the hostname/IP address and port
number on which the TimesTen Server is listening.
If the Network Address and Port Number values are correct, the TimesTen Server may
not be running or did not start. See "Starting and stopping the daemon on UNIX" in
the Oracle TimesTen In-Memory Database Operations Guide for information about starting
the server manually. See "Testing connections" in the Oracle TimesTen In-Memory
Database Operations Guide for more information about identifying this problem.
TimesTen Server failed
Check the server's log file. Server log messages are stored in the files specified by the
-userlog and -supportlog options in the ttendaemon.options file. See
"Creating and configuring Client DSNs on UNIX" and "Managing TimesTen daemon
options" in the Oracle TimesTen In-Memory Database Operations Guide.
The maximum number of concurrent IPC connections to the Server of a particular
TimesTen instance is 24,999. However, TimesTen has a limit of 2043 connections
(direct or client/server) to a single DSN.
Client/server users can change the file descriptor limit to support a large number of
connections. For an example, see "Installation prerequisites" in the Oracle TimesTen
In-Memory Database Installation Guide.
Cannot find Server DSN
On UNIX, verify that the Server DSN is defined in the sys.odbc.ini file on the
machine running the TimesTen Server.
On Windows, verify that the Server DSN is defined as a System DSN in the ODBC
Data Source Administrator on the machine running the TimesTen Server. See
"Creating and configuring a logical server name on Windows" in the Oracle TimesTen
In-Memory Database Operations Guide.
TimesTen Server failed to load DRIVER
This error only occurs on UNIX platforms. Open the sys.odbc.ini file on the
machine running the TimesTen Server and locate the Server DSN you are trying to
Note: If you typed the hostname or network address directly into the
Server Name field of the TimesTen Client DSN Setup, the Client tries
to connect to the TimesTen Server using the default port.
