Replication server for the assisted universal replication
The assisted universal replication can use a replication server. In this case, the replication is performed via the replication server. The transfer of replicas is automatically managed. Server-based replication can be implemented with immediate replication in which case data is synchronized immediately. The subscriber database sends the data to replicate, the replication is performed and the subscriber database retrieves the data to update. This operation can take quite a long time. This replication mode is recommended for a daily synchronization for instance (a salesperson synchronizes every evening with the office). Server-based replication can be implemented with deferred replication In this case, data is synchronized as it is exchanged with the server. When the server receives the data to replicate, it automatically prepares the data to return. This data will be returned during the next synchronization. This replication mode is recommended for a periodic synchronization for instance (whenever an order is placed). Installing the replication server Overview The replication server can be installed: - using the installation package available in the "Install\WDRServer" subdirectory of WINDEV or WINDEV Mobile.
- when installing a WINDEV application.
Installing a pack The installation package allows you to install or uninstalll the replication server. During the setup, you must specify: - the installation directory of the server elements.
- the deployment directory of the replication data. This directory will be the directory where the files required by the replication will be created.
Note If several virtual servers are available, it is necessary to specify the ones for which a replication server will be installed. At the end of setup, the site for configuring the replications will start. This site allows you to configure the different replications managed by the replication server. Note: To uninstall the replication server, simply relaunch the installation package. Remark The Web interface of the replication server requires the creation of an alias on the Web server. This creation is automated in most cases. If this alias has not been created, it must be created manually. This alias is named "SRVRPL_WEB". Example for creating the alias in Apache 2.2: Alias /SRVRPL_WEB/ "D:/PC SOFT/Replication Server 2024/SRVRPL/SRVRPL_WEB/"
<Directory "D:/PC SOFT/Replication Server 2024/SRVRPL/SRVRPL_WEB/">

</Directory> Using the site for configuring the replications The site for configuring the replications is used to: - create the different users of replications,
- configure the different replications managed by the site.
A name and a password are required to connect to the site. By default, only the administrator is created ("admin" name without password). Account management The "Accounts" tab is used to manage the different accounts of the replication users. Only the administrator exists by default.
The "Add an account" option is used to create a new account. The necessary elements are: - the login.
- the password and its confirmation.
- the email address.
From the table that lists the users, you have the ability to add or delete an account. Managing the publications The "Publications" tab is used to manage the publications of replications, which means the replications that can be used by the replication server.
The "Add a publication" option is used to create a new publication. Specify: - The name of the publication.
- The replication file to use (.WER file). This file was created by ReplicEdit.
- Replica preparation mode: by default, preparation is immediate: replicas are created immediately during replication.. If you choose a periodic preparation, the replication server will periodically prepare the replica. The replica is not the most up-to-date but the replication time is optimized.
If you choose periodic preparation, specify the parameters for the replica preparation period (daily, etc). The publication is created when validating the wizard. From the table that lists the publications, you have the ability to add or delete a publication. Managing subscriptions The subscription to a publication is performed:
