The following is the sequence of operations that takes place for the Item sync between PIM (Product Information Management--Advanced Product Catalog) and Oracle EBS R12
1. The Items are created/updated in PIM
2. PIM publishes the items
3. The items published by PIM comes to EBS (E-Business Suite, i.e. Oracle Item Master) via Middleware (MW) by calling the standard API- APPS.INV_EBI_ITEM_PUB
4. The item create/update status is sent back to MW from EBS
5. After the Item Creation/updation is successful in EBS, MW calls the custom package - XXINV.XXINV_4600_ITEM_ASL_UDA_PKG to update the categories and UDA attributes for the items created in PIM.
This custom package in turn calls the standard API- APPS.INV_ITEM_CATEGORY_PUB
Clients are facing performance issue during the Item sync between PIM and EBS via MW.
There is a resource contention which may result in dead lock errors while processing from MW and EBS resulting in longer run times.
The resource contention is happening between the following processes call, coming out from MW servers to EBS -
XXFUSN.XXFUSN_4599_ITEM_UDA_PKG >> XXPO.XXPO_4515_COMMON_PKG
>> XXINV.XXINV_4600_ITEM_ASL_UDA_PKG >>
APPS.INV_ITEM_CATEGORY_PUB >> APPS.MTL_CATEGORIES_PKG
APPS.INV_EBI_ITEM_PUB >> APPS.INV_EBI_ITEM_HELPER
>> APPS.EGO_ITEM_PUB >> APPS.EGO_ITEM_PVT
>> APPS.INV_ITEM_GRP >> APPS.INVPOPIF
APPS.INV_ENI_ITEMS_STAR_PKG >> APPS.ENI_ITEMS_STAR_PKG
Both of the above processes call the APPS.ENI_ITEMS_STAR_PKG package and update the table -ENI_OLTP_ITEM_STAR resulting in a deadlock.
This document is aimed toward Users whose only intension is to update the Items, Item categories and UDA attributes of Item.
The goal of this document is to instruct such Users, who do not have Business Intelligence installed, how to drop these packages and thereby preventing the update of the table ENI_OLTP_ITEM_STAR, resulting in the resolution of the deadlock issue and enhancing performance.
