Connect to JMS MQ
Connects to a JMS MQ queue provider server.
Command availability: IBM RPA SaaS and IBM RPA on premises
Description
Connects to JMS MQ queue provider server. You can use an existing JMS MQ connection by enabling the Storaged Configurations option, or configure it manually by leaving it disabled.
Script syntax
IBM RPA's proprietary script language has a syntax similar to other programming languages. The script syntax defines the command's syntax in the script file. You can work with this syntax in IBM RPA Studio's Script mode.
connectJmsMQ --queueprovider(String) --address(String) [--jniconnectionfactory(String)] [--fromconfiguration(Boolean)] [--port(Numeric)] [--timeout(TimeSpan)] (Boolean)=success (QueueConnection)=value
Dependencies
- You must have access to a server exposing the queue service. For JMS MQ, you must have access to an existing JMS MQ server before using this command.
- If you enable the
Storaged Configurationsparameter, you must have a previously configured queue provider in the IBM RPA Control Center. See Queue Provider for more information.
Input parameters
The following table displays the list of input parameters available in this command. In the table, you can see the parameter name when working in IBM RPA Studio's Script mode and its Designer mode equivalent label.
| Designer mode label | Script mode name | Required | Accepted variable types | Description |
|---|---|---|---|---|
| Queue Provider | queueprovider |
Required when the Storage Configurations parameter is enabled |
Text |
Connects to a Queue Provider configured in the IBM RPA Control Center. This option only works if the Queue Provider is already registered in the IBM RPA Control Center. |
| Address | address |
Required when the Storage Configurations parameter is not enabled |
Text |
URL address to connect to the server. |
| JNI Connection Factory | jniconnectionfactory |
Optional |
Text |
Connects to the queue server using JNI. |
| Storaged Configurations | fromconfiguration |
Optional |
Boolean |
When enabled, you can select a queue provider previously configured in the IBM RPA Control Center. |
| Port | port |
Optional |
Number |
Port number used to connect to the queue provider server. |
| Timeout | timeout |
Optional |
Time Span |
Maximum waiting time for establishing a connection to the queue server. If no value is defined, the default timeout of 5 seconds is used. It can also use the timeout value defined in the Set Timeout ( setTimeout) command. |
Output parameters
| Designer mode label | Script mode name | Accepted variable types | Description |
|---|---|---|---|
| Success | success |
Boolean |
Returns True if the connection contains a valid IP or hostname, otherwise returns False. |
| Connection | value |
Queue Connection |
Returns a variable with the connection to the queue provider. |
Example
The command connects to the JMS MQ queue provider according to settings stored in the IBM RPA Control Center.
defVar --name connectionValid --type Boolean
defVar --name jmsMqConnection --type QueueConnection
// Connect to the JMS MQ server with the stored settings.
connectJmsMQ --queueprovider testQueue --fromconfiguration connectionValid=success jmsMqConnection=value
// Displays whether or not you have successfully connected to the server.
logMessage --message "${connectionValid}" --type "Info"
Limitations
- This command does not create a new queue. You can create a new queue by creating a new variable with type
Message Queueand adding items to the queue using the Enqueue (enqueue) command or by obtaining a queue previously registered in the IBM RPA Control Center. - The
successparameter returnsTrueif the connection is valid, but the command does not check if the connection was successfully established.
