Common Questions After Upgrading to PSQL
This section contains information that you should read after running the installation program. If you are having problems with your installation, go to Chapter 14, Troubleshooting After Installation, or get help online from the Knowledge Base at the PSQL website.
How to Handle Data Source Names (DSNs)
The following table describes the procedures for upgrading your DSNs after you have installed the PSQL upgrade.

DSN Considerations After a PSQL Upgrade
Scenario
Discussion
You have existing DSNs created with a version of PSQL prior to Pervasive.SQL 2000i SP4
You must delete all existing DSNs before you upgrade. Once you have upgraded, re-create the DSNs to access the existing databases.
New DSNs should connect to a named database, not to an Engine DSN because Engine DSNs are deprecated.
See ODBC Connection Strings in ODBC Guide.
You have existing DSNs created with Pervasive.SQL 2000i SP4 or a later version of PSQL
You should be able to access your databases by connecting to the existing DSNs.
Note, however, the recommendation is that new or revised 32-bit applications should connect to a named database, not to an Engine DSN because Engine DSNs are deprecated.
If you want to port your 32-bit application to 64-bit, then make the following changes.
•
If the application uses DSN-less connections that connect using “Pervasive ODBC Client Interface,” change the connection string to “PSQL ODBC Interface.”
•
If the application uses Engine or Client DSNs, you must create 64-bit DSNs that connect to a named database. (Also note that on 64-bit Windows operating systems, 64-bit system DSNs are distinct from 32-bit system DSNs because of the registry design.)
See ODBC Connection Strings in ODBC Guide.
You do not have any PSQL DSNs defined
For details about creating DSNs, see DSN Setup and Connection Strings in ODBC Guide.
If you want to use DSN-less connections for 32-bit applications, use the connection string “Pervasive ODBC Client Interface” and connect to a named database. For 64-bit DSNs, use the connection string “PSQL ODBC Interface” to connect to a named database.
How Do I Convert My Files From Previous PSQL Products?
Converting your data files to 9.x format is not required, but you must convert them if you wish to take advantage of new features offered by the PSQL v12 engine.
Users of previous Btrieve versions: Use the Rebuild utility to convert your existing pre-6.0 or 6.x files to 7.x, 8.x, or 9.x format. For more information, refer to the Advanced Operations Guide.
What User License Was Installed with PSQL?
A trial license is installed if you leave the license number blank during installation.
There is no configuration necessary for the license. After installation, you can use the License Administrator utility to view your installed licenses. See the PSQL User's Guide for more information on the License Administrator utility.
