Database considerations

All platforms​

Determine which database type(s) you want to use.​

Refer to the Database section for more information related to the database types compatible with SoftExpert Suite.

Note that SQL scripts will be executed during the installation process.​

A series of SQL scripts will be executed to create the objects in the database and insert the configuration data. These scripts are executed automatically by the SoftExpert Suite installation tool. The SoftExpert Suite installation will be completed only if these scripts are executed successfully.

SQL Server​

Set up SQL Server Collation​

The collations that may be used in western languages for the SoftExpert Suite database in SQL Server are:

  • SQL_Latin1_General_CP1_CI_AS
  • SQL_Latin1_General_CP1_CI_AI
  • Latin1_General_CI_AS
  • Latin1_General_CI_AI

The CI (Case Insensitive) parameter of the collation must always be used. We recommend using the AI (Accent Insensitive) parameter for new databases, as of 2.1. For eastern languages, contact SoftExpert Support.

caution

For TLS 1.2 connections to SQL Server database, certain requirements may be necessary. The installation and update guides have further information on those requirements.

warning

It is important to be aware of the Express version limitations. See further details in the Servers > Database section.

READ_COMMITTED_SNAPSHOT isolation level configuration​

In order to prevent locks and deadlocks in reading operations performed in the SoftExpert Suite database, it is possible to use isolation by Snapshot, which will version each record in the tempdb. More information at http://msdn.microsoft.com/en-us/library/ms173763.aspx.

To enable this parameterization, run the commands below, without having any active connection in the <database>:

ALTER DATABASE <Database> SET ALLOW_SNAPSHOT_ISOLATION ON;
ALTER DATABASE <Database> SET READ_COMMITTED_SNAPSHOT ON;

Oracle​

Determine your NLS and character-set requirements​

As of version 2.0.13, SoftExpert Suite supports the WE8MSWIN1252 (non-unicode) and AL32UTF8 (unicode) character sets. However, we advise using AL32UTF8 only when there is a need for languages that cannot be saved in the non-unicode format.

Determine the Oracle client NLS​

After defining the character set to be used by the Oracle database server, you must define the NLS_LANG environment variable for the client installations that will connect to the server. The environment variable must be in line with the character set of the server. In an environment where the server is running with WE8MSWIN1252, for example, it is common to use the NLS_LANG set up with AMERICAN_AMERICA.WE8MSWIN1252.

Create/manage your tablespaces​

SoftExpert Suite uses one tablespace for data, and one for indexes. The size required for an initial installation should be 2GB (data) and 200MB (indexes). These numbers tend to increase as the features of the tool are used, especially when documents are added through the SoftExpert Document component or forms. Therefore, tablespace growth must be constantly monitored, and ensuring that there is size available for it is required.

warning

Important: We recommend using a controlled directory to store the files, which helps slow down database growth.

PostgreSQL​

Determine your encoding requirements​

Server and client require en_US.UTF-8 encoding for all languages.

caution

ATTENTION

  • The Postgres database must necessarily use the en_US.UTF-8 collate, exclusively, in order to ensure compatibility with SoftExpert Suite.

Network configuration​

To access the PostgreSQL server, you must enter the customer's network configurations in the pg_hba.conf file and enable external access in the postgresql.conf file (the PostgreSQL service must be restarted). Refer to the "SoftExpert Suite - Installation Guide" document, "Database configuration" section (Linux or Windows) for information on the PostgreSQL network configuration.
