Database Requirements

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

PostgreSQL

Comes bundled with the product (PostgreSQL version 14.7).

For Remote PostgreSQL, OpManager supports PostgreSQL versions 14.7 to 14.x. 

In case of failover, please use MS SQL.

Microsoft SQL

1. Supported versions:

SQL 2019 (from build 125379) | SQL 2017 | SQL 2016 | SQL 2014 

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.
4.Developer edition of SQL Server is 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 (applicable only for OpManager Enterprise Edition). 

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.

6. User-role requirement:

Server roles - "dbcreator", "public" and "sysadmin".

User Mapping - Map this login to "master" with database role ownership as "db_owner" and "public". Click here to learn more.

List of Ports to be opened in Firewall

For device discovery
  • OpManager uses ICMP protocol (which has no TCP/UDP ports) by default during device discovery.
  • Associate credentials during discovery for proper classification of devices and data collection. Refer below for the default ports used for each protocol.

For data collection and monitoring of devices

Open the below ports in the firewall to ensure uninterrupted monitoring of your devices.
  • WMI - 5000-6000 and 49152-65535(TCP) - Bidirectional
  • WMI - 135(TCP) - Inbound
  • SNMP-161(UDP) - Bidirectional
  • SNMP Traps- 162(UDP)- Unidirectional (From monitored device to OpManager server)
  • Telnet- 23(TCP)- Bidirectional
  • SSH- 22(TCP)- Bidirectional
  • ICMP- Used to check the availability status and to add a device. - Bidirectional
  • Default syslog port 514(UDP)- Unidirectional (From monitored device to OpManager server)
Note: OpManager uses ICMP for its initial discovery of devices. If your device does not support ICMP, discovering it via 'Discovery Profile' is not possible. You will only be able to discover the device through 'Add Device' or 'CSV file' options.

Ports used by Applications Manager plugin

The following are the ports used by Applications Manager plugin:

  • HTTP - 9090
  • HTTPS - 8443
