WFR Import Is Failing With "System.OutOfMemoryException" or "Out of memory" In RTS (Doc ID 2113404.1)

Last updated on JANUARY 08, 2018

Applies to:

Oracle WebCenter Forms Recognition - Version 11.1.1.8.0 to 11.1.1.9.0 [Release 11g]
Information in this document applies to any platform.

Symptoms

When attempting to process a particularly large .TIF file, the following Run Time Server (RTS) error occurs:

|10| 16:13:57.550 | 2424 | 4596508k/3791644k | 6060520k/10713948k | 1380640k/1359904k | 1411 | 98/56 | Can not add document A_sample doc 1.wdc ---> Exception of type 'System.OutOfMemoryException' was thrown.

This error also may appear, depending on startup conditions:

|10| 16:21:34.393 | 2424 | 4600824k/3787328k | 6132824k/10641644k | 1438784k/1355456k | 1411 | 98/56 | Can not add document A_sample doc 1.wdc ---> Out of memory


The issue can be reproduced at will with the following steps:
1. Create a project and RTS Instance that uses an Oracle DB for Batch processing.
2. Add a very large (>45MB) .TIF file to the Import Directory (the size of the TIF that causes the problem may vary depending on the environment).
3. Startup the RTS Instance.
4. Observe the errors in the RTS Statistics display port.

Changes

 Upgrading from 10g to 11g version and/or changing from file system batch processing to database batch processing.
