Database Requirements

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

PostgreSQL

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

Microsoft SQL

1. Supported versions:

SQL 2022 (from build 12.8.452) | SQL 2019 | SQL 2017 | SQL 2016

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"(Windows)/"bcp"(Linux) 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.

For Windows:

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.

For Linux:

For BCP utility in Linux, mssql-tools (Microsoft ODBC driver for Linux) should be installed on a NetFlow Analyzer installed machine. Please follow the steps in the document provided below to install Microsoft ODBC driver on Linux servers.

https://learn.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server

The command to install ODBC driver is different for every Linux flavor. Please choose the correct Linux flavor and install the ODBC driver.

Steps to move BCP utility to NetFlow Analyzer :
- After the ODBC driver is installed in Linux servers, the bcp utility files can be found in the below mentioned path. Copy both bcp and bcp.rll files to <opmanager_home>/bin and start NetFlow Analyzer once.
- For ODBC driver version 18: bcp file in /opt/mssql-tools18/bin/ and bcp.rll file in /opt/mssql-tools18/share/resources/en_US/
- For other versions of ODBC: bcp file in /opt/mssql-tools/bin/ and bcp.rll file in /opt/mssql-tools/share/resources/en_US/
