Thread Recommendations

Configure the Fast and List queue values in ar_install_dir/conf/ar.cfg with the following parameters and values:

  • Private-RPC-Socket: 390601 1 1
  • Private-RPC-Socket: 390603 1 1
  • Private-RPC-Socket: 390620 6 6
  • Private-RPC-Socket: 390626 3 3
  • Private-RPC-Socket: 390635 6 6

Note

Fast and List thread settings are hardware configuration based limitations.
There is no configuration file to configure the Customer Access Interface (CAI) plug-in registry value. Entry is saved in the database. Do manual steps 7-9.

Manual Steps

  1. Log in to the User Tool as an Administrator.
  2. Access the BMC Remedy AR System Administration Console.
  3. Select System > General > Server Information
  4. Enter the Port and Queues information in the Server Information dialog box.
  5. For each type of thread, modify the min threads and max threads for the RPC program as listed in the following chart. Note that the queue for Loopback and CAI Thread is shared.
  6. Click OK.
  7. Open the CAI Plug-in Registry form in new mode.
  8. Create an entry with the following values:
    • Private Queue #*: 390626
    • Number of Threads*: 3
  9. Click Save.
  10. Restart the BMC Remedy AR System server for the CAI Plugin threads to take effect.

Note

CAI plug-in registry setting is a hardware configuration limitation and dependent on fast/list thread settings.

Fast and List Thread Settings

Queue Number Purpose No. of Threads Comments

Private-RPC-Socket: 390601

PAlert Queue

1

None

Private-RPC-Socket: 390603

Escalation Queue

1

Ensure that escalations use these threads.

Private-RPC-Socket: 390620

Fast Queue

6

None

Private-RPC-Socket: 390626

Loopback Socket Queue / CAI Thread

3

Uses the same queue as CAI to share threads, so only one entry is needed. Create the entry in the CAI Plug-in Registry form with that private queue number matching number of threads.

Private-RPC-Socket: 390635

List Queue

6

Set min and max to the same number.


Following is an example of the BMC Remedy AR System Server Information screen and the CAI Plugin Registry screen. The values must match.
