The following table lists the basic requirements for your OpManager database server.
SQL 2019 | SQL 2017 | SQL 2016 | SQL 2014
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.
Mixed mode (MSSQL and Windows Authentication).
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.
The command to install ODBC driver is different for every Linux flavor. Please choose the correct Linux flavor and install the ODBC driver.
Note: NetFlow Analyzer runs in both Windows and Linux, supports NetFlow® versions 5/7/9,sFlow® , cflowd® ,J-Flow® , IPFIX® , NetStream®. To know which devices it supports refer Configuring Cisco Devices section of the User Guide.
