Database Requirements

The following table lists the basic requirements for your OpManager Plus database server.

PostgreSQL

Comes bundled with the product
In case of failover, please use MS SQL.

Microsoft SQL

1. Supported versions:

SQL 2016 | SQL 2014 | SQL 2012 | SQL 2008

2. Important Notices:

1. For production use 64 bit versions of SQL
2. Recovery mode should be set to SIMPLE.
3. SQL and OpManager should be in the same LAN. Currently WAN based SQL installations are not supported.

3. Collation:

English with collation setting (SQL_Latin1_General_CP1_CI_AS)
Norwegian with collation setting (Danish_Norwegian_CI_AS)
Simplified Chinese with collation setting (Chinese_PRC_CI_AS)
Japanese with collation setting (Japanese_CI_AS)
German with collation setting (German_PhoneBook_CI_AS)

4. Authentication:

Mixed mode (MSSQL and Windows Authentication).

5. BCP:

The "bcp.exe" and "bcp.rll" must be available in the OpManager bin directory.

The BCP utility provided with Microsoft SQL Server is a command line utility that allows you to import and export large amounts of data in and out of SQL server databases quickly. The bcp.exe and bcp.rll will be available in the MSSQL installation directory. If MSSQL is in a remote machine, copy bcp.exe and bcp.rll files and paste them in the <\OpManager\bin> directory.

The SQL server version compliant with the SQL Native Client must be installed in the same Server.

General Information

Antivirus scanners interfering with database files may affect normal functioning of the database. Please make sure that your anti-virus scanners do not affect the functioning of the product/database.
