Preparing to Install Pervasive DataExchange. This chapter provides important information including system requirements and platform specific notes that are relevant to your operation.

Double-click REG_DWORD for the key.

|
Click OK.
|
The REG_DWORD value should read 0x00000000 (0).
Note Changing this registry setting to zero grants Pervasive PSQL administrative authority to everyone who has access to the Terminal Server client machine. To restrict Pervasive PSQL administrative authority, you may want to restore the default value of the registry setting after DataExchange is installed. To do this, change the REG_DWORD value back to 1 (see step 4 in To modify the security registry setting on a Terminal Server client).
If the installation fails before the program copies any files to the target installation directory, refer to the installation log file (replinst.log) in the <drive>:\Windows directory.
DataExchange installs a service called the notification agent if the machine contains the Pervasive PSQL Server product. The notification agent is not available if you install DataExchange on a machine with the Pervasive PSQL Workgroup product. See dxagent in Pervasive DataExchange User’s Guide.

If the installation does not start automatically, run the following command from the operating system: drive:\setup where drive is the drive letter of your CD-ROM device.

At the end of the evaluation period, the replication engine returns an error when it tries to start. You may apply a license key at any time. See To upgrade an evaluation license.

To install a First Site, click Yes if you have not installed a First Site on your replication network and continue with the next step. Otherwise, click No.

Figure 3-2 Site Information
|
|
The Site Name identifies your machine on the replication network. The name can be whatever you want. Accept the default or enter a more descriptive site name.
|
|
|
The Host Name identifies this machine to the DataExchange Engine. If your machine has a fixed IP address and you prefer to use it, enter it here. If the address is assigned by DHCP, accept the machine host name by default.

Pervasive DataExchange Data Synchronization Edition provides different methods to design and deploy a database for replication. The methods involve a variety of decisions, which are explained in Pervasive DataExchange User’s Guide. See Data Synchronization Deployment Models in that guide.
Pervasive PSQL provides security models for Btrieve applications. However, the activated databases created by DXdeploy do not contain security, even if the source database does. You may add security to a replication database if you choose. See Pervasive PSQL Security in Pervasive DataExchange User’s Guide. For more details, see also the chapter on Pervasive PSQL Security in the Pervasive PSQL Advanced Operations Guide.
Pervasive DataExchange files are no longer installed to <drive>:\pvsw\bin. This change comes as Pervasive Software adopts the same program and security guidelines established by Microsoft for its current operating systems.

The uninstall program removes all DataExchange components from your system. Uninstall removes databases registered by Pervasive PSQL that are located under <Installation Directory >\Replication.
The uninstall program does not remove any databases that were created in locations other than under <Installation Directory >\Replication. It also does not remove the DSNs and database names associated with these databases.
If you have activated databases located under <Installation Directory >\Replication, perform the following actions before you uninstall DataExchange:
|
|
Deactivate each database with the dxdeact utility. See dxdeact in Pervasive DataExchange User’s Guide.
|
|
|
Remove the template with Template Remover wizard. See trwizard in Pervasive DataExchange User’s Guide.
|
Note You are not required to uninstall DataExchange before upgrading it. If you want to upgrade DataExchange, see Upgrading Pervasive DataExchange. An uninstall removes all DataExchange design and activated database information from your system, as well as any databases created under the <Installation Directory >\Replication directory. Uninstalling requires that you redesign your replication databases.
