Installation of DataCentral¶
Preparation¶
Access Rights¶
In order to be able to index data from different servers, DataCentral requires sufficient access rights to the corresponding servers.
You can ensure this with the help of a dedicated account that is assigned sufficient rights with which the DataCentral services can log in.
Please make sure that this is already available during installation, as you should already have the account stored to avoid problems later on.
Database¶
Before installing DataCentral, we recommend selecting a suitable database.
Note
For testing purposes DataCentral offers a download and automatic setup of MS SQL Server Express. Which comes with limitations in terms of database size and available resources. See Microsoft documentation for more details.
We recommend the use of Microsoft SQL Server. Please note that this must be an empty database.
You should create the database with a dedicated account before installing DataCentral in order to avoid potential problems during operation. However, this is still possible after installation.
To avoid possible overlaps with database-specific names for authorizations, we use our own abstract authorization types here.
The required database authorizations are divided into 6 types:
Permission |
Description |
|---|---|
Select Permission |
The permission to execute SELECT statements on the database. |
Update Permission |
The permission to execute UPDATE statements on existing tables in the database. |
Insert Permission |
The permission to execute INSERT statements on existing tables in the database. |
Create Permission |
Permission to create new tables, views, foreign keys, stored procedures, triggers and indices in the database. |
Age Permission |
The right to change the properties, with the exception of ownership, of a specific collateralizable element. |
Microsoft SQL Server also offers the option of using Windows authentication to connect to the database.
When setting up the logins on the SQL server, it must be taken into account that the dedicated scan account (Access Rights) and the administrator using DataCentral have access to the database when using this authentication type.
Installation Process¶
The installation process follows a simple sequence.
Execute the Setup.exe.
Select an installation language.
Please read the license terms and accept them.
Select the demo version or enter your license key if you already have one.
Specify an installation directory and then specify whether you want to create an entry in the start menu and a desktop icon. Then start the installation process.
Once the installation is complete, specify the account under which the indexing services are to run. Enter the account and password (Access Rights). Additionally ensure the checkbox “Enable central index server (DataCentral Service)” is activated. This is mandatory for the usage of DataCentral with UltraSearch. Alternatively you can use the local system account for the services. We do not recommend using this because this account has usually not the necessary rights to access network drives or the database with Windows Authentiaction.
Specify the certificate which should be used for secure communication between UltraSearch and DataCentral. You can choose between the usage (and installation) of your own certificate file (pfx-file) or the usage of a self-signed certificate, which will be generated and installed automatically on the server. Explaination on how to configure the certificate you selected here for the usage with UltraSearch can be found in Integration in UltraSearch.
Complete the installation and open DataCentral.
