Entity Sync
Locked

Quick question - with the entity sync function can you run push and pull at the same time?
I have a feeling that this is not a good idea but still trying to work out how the sync works exactly. We have it up and running between three locations. We consider the master database in Hong Kong with remote servers in USA and China. Thanks Sam |

Hey Sam,
Although, we can schedule the push and pull services at different times through RecurrenceRule, there is still a possibility that push and pull might run at the same time. To make sure this doesnt happen, you can write a piece of code in both runPullEntitySync and runEntitySync services that checks whether runEntitySync or runPullEntitySync service is running or not through JobSandbox table. So when in runPullEntitySync, we check whether runEntitySync service is running and if it is, we return an error and this re-schedules runPullEntitySync service again for later. This should make both services mutuallly exclusive. Its the first pull that takes hours, but after that it should be quick enough. So scheduling push pull service in a gap of 1-2 hours should work. I am sure you must have referred this document - http://docs.ofbiz.org/display/OFBIZ/Sync+Setup+Notes+and+Example but that should be some information. Also, on another note, I had an issue with Inventory when pushing data across. The problem occurred when a new InventoryItem record was created on POS. So now when that InventoryItem is created on MCS, it triggers an ECA service 'createInventoryItemCheckSetAtpQoh' and this creates InventoryItemDetail records again thus doubling the inventory as InventoryItemDetail records for the same InventoryItem were being pushed as well. I had to filter InventoryItemDetail records from the create records list before push to avoid this problem. Hope this helps, Thanks, Amit Shinde Amicon Technologies Pvt. Ltd., Mumbai, India.
