Create an F5 iRule for CA Process Automation

An iRule routes operator requests that target the touchpoint of a clustered Orchestrator. F5 creates a URL from this information and uses that URL as the touchpoint destination. To create an F5 iRule for CA Process Automation, copy the provided iRule definition into the Description text box. Then, set the values for

• PAMPOOL: Set the name for the pool that is used for both deprecated communication and simplified communication, for example "PAMSRVRPOOL"
• PAMWSPOOL: Set the name for the pool the is used for simplified (web socket) communication, for example, "PAMJETTYPOOL"
• NODE1, NODE2, and so on: Set the IP address of each node in the PAMWSPOOL
• WSPORT: The port that is used for simplified communication, either 80 (basic) or 443 (secure)

Note: An iRule identifies one Orchestrator cluster node for a request that targets the touchpoint of a clustered Orchestrator. The decision is based on the URL.

Follow these steps:

1. Log in to F5.
2. Select the Main tab, click Local Traffic, and then click iRules.

   The iRules List is empty if you are setting up iRules for the first time. The iRules List displays the following details for each iRule: the iRule name and the partition.

3. Click Create.

   The New iRule page appears.

4. Complete the Properties section.

   Name

   Specifies the iRule name.

   Definition

   Specifies the iRule definition. Copy the text from The iRule Definition into this text box.

   Note: The programming language that is used for iRules is Tcl, Tool Command Language.

   Extend Text Area

   Specifies whether to extend the text area of the Definition text box to its maximum size.

   Selected - Extends text area to its maximum size.

   Cleared - Presents text area in a size that is less than maximum.

   Wrap Text

   Specifies whether to wrap the text to fit in the Definition text box rather than display a horizontal scroll bar.

   Selected - Wraps text that extends beyond the viewable portion of the Definition text box, excluding a horizontal scroll.

   Cleared - Presents text as entered, with a horizontal scroll bar if needed.
