Why?
Some users have reported difficulty locating or installing a separate license file when first deploying OpenLink Universal Data Access (UDA) Drivers. This distracts from their primary goal — evaluating the advanced interoperability and connectivity features of OpenLink’s high-performance ODBC and JDBC drivers.
To simplify initial deployment and provide immediate access for evaluation, OpenLink Single-Tier (Lite) UDA Drivers include an automatic, built-in demo license.
What?
The built-in demo license is included in current versions of all OpenLink Single-Tier (Lite) UDA Drivers for ODBC and JDBC.
Its attributes are:
- number of concurrent ODBC/JDBC connections: 1
- number of records fetched in SQL: 25
- license expiration time after activation: 10 minutes
How?
This built-in demo license becomes active automatically when any of the following conditions are detected:
- the OpenLink License Manager (
oplmgr) is not running - the License Manager is not responding
- the driver-specific license file (e.g.,
sql_lt.lic,jdbc_lt.lic) is not found - the license file is for an older driver version
- the license file is for a different operating system
- the license file has expired
Whenever this occurs, the driver falls back to the built-in evaluation license.
ODBC and JDBC Client Connections
Every time an application attempts to establish an ODBC or JDBC connection, the driver checks the status of the active license.
If the built-in license has expired, the driver returns an error such as:
*** Error 08004: LI100: Number of licensed connections exceeded
While the demo license is active:
- Only one concurrent connection is permitted.
- All SQL query results are limited to a maximum of 25 rows.
This affects all SQL execution modes, including metadata retrieval and pass-through SQL.
Frequently Asked Questions
How can I determine if the built-in demo license is in use ?
This can be determined if the license expires after 10 minutes of use or the number of SQL results is limited to 25 rows or only one connection is allowed.
Are there any licensing error conditions that do not trigger the built-in demo license?
No.
Any license verification failure will result in activation of the built-in demo license.
