To handle high transaction CAPS environments, system administrators can enable threaded posting. To enable threaded posting, modify the web.config.txt file located on the CAPS machine.
For Simphony 19.x users, the following key needs to be manually entered in the appSettings
section:
<add key="MaxMrequestPlaybackThreads" value="x" />
In the syntax provided in the example above, x represents the number of threads.
The number of threads used depends on the volume of Mrequest messages. Also, the number of connections is derived from the number of threads. Under enough load, the value sets the upper limit of threads. There is a point when adding connections decreases performance. As such, if you have a posting backlog on CAPS, it is suggested to use 1 thread for every 25 workstations.
Configure a service host for CAPS. See Configuring the Service Host for CAPS in EMC for instructions.
Assign the employee privilege to download software, install and authenticate clients and Service Hosts using CAL.
Beginning with Simphony version 2.9.1 (which includes CAL version 139), users must have the employee privilege assigned to the appropriate role to successfully authenticate workstations, Android devices, and Kitchen Display Systems (KDS). After installing or upgrading to Simphony version 2.9.1 or later, you must assign the privilege to a user’s role. When the Role option is set, employees can use their EMC logon credentials when CAL’ing devices. See Allowing Employees to Install and Authenticate POS Clients and Service Hosts for instructions to assign the privilege.
Set the CAL deployment schedule. See Configuring the Deployment Schedule to Install CAL on a POS Client Workstation without Ops for instructions.
