To install DataExchange to a Terminal Server client, you must first modify a registry setting on the Terminal Server client. See Installing Over Windows Terminal Services in Getting Started with Pervasive DataExchange.
If you have activated databases that are located under <Installation Directory >\Replication, first deactivate them then delete the replication template with the Template Remover wizard. If you do not deactivate the database then remove the template, uninstall leaves the database files and the associated replication files. The remaining files do not cause any problems but you may prefer to reclaim physical storage by deleting them. You may delete the files manually if you want. Remember, also, to remove the DSN associated with the database.
See Working with the Examples for a discussion of how to deactivate a database and remove a template.

Both of these services must be started for the Pervasive PSQL database engine to function correctly.
If the Workgroup engine is installaed as an application, you can start it from the operating system Start menu or Start screen.
Use the Pervasive PSQL License Administrator utility to determine if you have a permanent license installed for Pervasive DataExchange or to see if a temporary license has expired. See the the License Administrator chapter in Pervasive PSQL User's Guide.

If the Workgroup engine is installaed as an application, you can start it from the operating system Start menu or Start screen.
You can change the default location of the logs, which is <Installation Directory >\Replication\LogFiles. If you want, you can also change the default log size and the default number of files kept (a history). You can view the LogFiles folder from the operating system Start menu or Apps screen.
In the case of the DRE.log, when the log file reaches its maximum size, the file is reassigned to the next history file name. For example, when the Dre.log reaches its maximum size, it gets renamed to Dre.lo1 and a new Dre.log gets created. Dre.log is then empty and starts acquiring data once more. When the maximum size is again reached, Dre.lo1 gets renamed to Dre.lo2, Dre.log gets renamed to Dre.lo1, and a new Dre.log is again empty and able to acquire data. The Maximum Logs to Keep setting determines the extent of the history retained: lo1, lo2, lo3, and so forth.
Other DataExchange components automatically start a new log file when the utility or service executes. In this situation, each time the utility is activated the associated XXX.log file is copied to a new XXX.lo1 file. The utility then begins logging in the now empty XXX.log file. Again, the Maximum Logs to Keep setting determines the extent of the history retained: lo1, lo2, lo3, and so forth.

The Initiate Replication dialog allows you to start a replication. (Right-click Replication - Connected in the PCC tree, then click Tasks Initiate Replication to display the dialog.) On this dialog, you select a source database and the sites to replicate with. The list of sites to replicate with may seem inconsistent depending on how you activated your Partner Sites.
In the Initiate Replication dialog, if you select as the source database the First Site or PS1, neither shows PS2 as a site to replicate with. This may lead you to question, “what became of my second Partner Site? Why isn’t PS2 in the list?”
If your dynamically created tables are not being replicated, verify that the file matching patterns in the dCNF table are correct. DataExchange provides a utility, Dxdynpath, to help you verify file matching patterns. See dxdynpath in Pervasive DataExchange User’s Guide.
