There are so many commands in Tibco EMS which can be used to perform different tasks in EMS administration. But we may not use all these commands frequently. In this post, I am sharing some commonly used commands in Tibco EMS administration.
I
If you type ‘I’ in the administration tool, you will get an overview details of the EMS server.

Create
This command is used to create EMS objects and configurations. See below for the full list of creating command.
Create a User:
create user <name> [<description>]
[password=<password>]
tcp://EMS01:7020> create user user1 "Test User" password=password
User 'user1' has been created
Create a Group:
create group <name> [<description>] tcp://EMS01:7020> create group group1 "Sample Group" Group 'group1' has been created
Create a Topic or Queue:
create topic <name> [<properties>] tcp://EMS01:7020>create topic SAMPLE.TOPIC secure create queue <name> [<properties>] tcp://EMS01:7020>create queue SAMPLE.QUEUE secure
Note: for queues and topic we have different destination properties and secure is one of them. Please read Destination properties in Tibco EMS to know more.
Create a route & Durable:
create route <name> url=<url> [zone_name=<zone-name>]
[zone_type=<zone-type>]
[<properties>]
tcp://EMS01:7201>create route EMS02 url=tcp://EMS02:7201 zone_name=Z1 zone_type=1hop
create durable <topic> <name> [<properties>]
tcp://EMS01:7201>create durable SAMPLE.TOPIC EMS02 route
We need some pre-configuration to make a route between the EMS server. Read How to create a route between the EMS server to know the full steps.
Create a Bridge :
create bridge source=<type>:<name>
target=<type>:<name>
[selector=<selector>]
tcp://EMS01:7020>create bridge source=topic:TECH.TOPIC
