Avoid Install Base Errors! Apply New R12 Consolidated Patch
By LuciaC-Oracle on Apr 11, 2014
Recently we've found that some customers are reporting errors after applying Patch 17182398:R12.CSI.B. We found that this was due to not applying a pre-requisite patch (Patch 16914038:R12.CSI.B). So, to avoid this problem, the Install Base development team have released a new consolidated patch which includes the pre-requisite: Patch 18479621:R12.CSI.B: ORACLE INSTALLED BASE 12.1.X CONSOLIDATION.
This patch supersedes Patch 17182398:R12.CSI.B and should be applied by all new R12 IB implementations or any R12.1.x upgrades. The patch includes a large number of fixes and is recommended for all Install Base customers. If you have already applied Patch 17182398:R12.CSI.B with its correct pre-requisite patch, then there is no need to apply Patch 18479621:R12.CSI.B.
All details about this new consolidation are included in article: About R12.1.X Consolidated Patch For Oracle Installed Base - 18479621:R12.CSI.B (Doc ID 1642057.1)
