GOAL

What Is Correct Number of Processes for Receiving Transaction Manager (RTM)?

SOLUTION

There is no specific value to suggest for #processes; rather, the value must be calculated.  It is suggested to set to a minimum of 10 for production or high fidelity environments and increase as needed per details in this note.  In all cases, #processes should be AT LEAST 3. 

The information below applies only if one or more of the following receiving transaction activities are processed:
1. Core Applications, Mobile/MSCA and WMS (Receipts, Receiving Transactions, Corrections, Returns, etc) when Profile RCV: Processing Mode=On-line
2.  Confirm Receipts
3.  Ship Confirm for Internal Orders
4.  Inter-Organization Transfers
5.  Internet Procurement (iP) Receiving

The activities listed in 2-5 (above) always use On-line, regardless of the value set for Profile RCV: Processing Mode

 

 Navigation to check # Processes:

• System Administrator (or comparable) Responsibility > Concurrent > Manager > Define
• Query for Manager='Receiving Transaction Manager' 
• Click Work Shifts button and review value in Processes field
• Change the value using guidelines referenced below
• Save

Note: additional Receiving Transaction Managers may be setup, so be sure to check for other records (use down arrow to go to the next record)

1.  Calculate the max number of concurrent Users for the following activities:
Core Applications receiving activities (Receipts, Receiving Transactions, Corrections, Returns, etc) when Profile RCV: Processing Mode=On-line +
iP Receipts +
Confirm Receipts +
Ship Confirms for Internal Orders +
Creation of InterOrg Transfers +
Receiving activities using Mobile/MSCA and WMS when Profile RCV: Processing Mode=On-line

Divide the Total from above by 3 or 4. This is will be (approximately) the suggested value for # Processes.

2.  If using Real Application Cluster (RAC) environment, review Note 1067213.1 (How to Setup Receiving Transaction Manager (RTM) When Using Real Application Cluster (RAC))

3.  R12: Set profile 'Concurrent:TM Transport Type' = QUEUE

Example:
There are 500 total Users who perform the transaction activities listed above, but the most Users work at the same time never exceeds 36. For this example, # Processes for Receiving Transaction Manager should be 12 or 9 (36 divided by 3 or 4).

Please do NOT indiscriminately set # Processes to a high value, as the processing capability of your instance is also a factor (which cannot be included in the calculation as there are too many variables). Instead, increase # Processes by 5 or 10 then monitor for a few days; repeat process to increase the value if Online transactions time out (APP-FND-00204: RCVOLTM TM-TIMEOUT) or if rcv_transactions_interface records get stuck as ONLINE/PENDING/PENDING.

Please do not set # Processes for Receiving Transaction Manager higher than 75 without first checking with Oracle Support (log Service Request for Inventory / Receiving).  Please note that 75 is not a magic number; rather, most Customers have much smaller value for # Processes.  If the value is already 75 or higher and there have been no reported problems, just leave value as is.
