Install, upgrade, and uninstall OMS in separated mode

This topic describes how to install, upgrade, and uninstall OMS in separated mode by using OAT.

Prerequisites

Before you install OMS in separated mode, make sure that the following conditions are met:

• You have installed OAT and logged in as a super administrator or an O&M engineer. For more information, see Install OAT.
• You have added a server to install OMS. For more information, see Add a server.
• Your server meets the requirements for installing OMS. For more information, see Resource configuration specifications of OMS.
• You have created the MetaDB component for OMS. For more information, see Create MetaDB.

Considerations

• In a multi-region deployment, each region must have a Management Container and a Component Container.
• The console (8089) and CM (8088) services reside in the Management Container. When configuring load balancing, follow the deployment pattern of the Management Container, setting up one load balancing rule per region.
• The Management Container supports setting a primary region: after setting a primary region, only the first management node in the primary region starts the console and CM services; other management container nodes only start the CM service.

     Console Service Port	Specify the Console service port number.
     CM VIP	The CM VIP is automatically filled in and cannot be edited.
     CM Service Port	Specify the CM service port number.

   • OBDNS has been created.: OBDNS automatically adds a load rule for the product's actual HTTP service address based on the Domain Name and VPORT you entered. Additionally, if you have selected "Created MetaDB", OBDNS will also automatically handle domain name resolution for MetaDB-related servers.

     Parameter	Description
     Select Created OBDNS	Select an existing OBDNS.
