Out of Memory or Missing Object Errors During OWB 11g MDL Import (Doc ID 1220493.1)

Last updated on DECEMBER 03, 2015

Applies to:

Oracle Warehouse Builder - Version 11.1 and later
Information in this document applies to any platform.

Symptoms

When importing large MDL files, OWB 11g may exhaust the allocated Java heap space. This can result in "out of memory" errors or missing object errors.

For example:

Error at line 1,314,228: MDL1261: Error importing OWBAssoc_CopyOf
MDL3001: ConnectFrom <STF.INOUTGRP1.AR> not found for ATTRIBUTE <DWH.EDW.L_ROBJECT_I.AR>

or


Error at line 1,314,228: MDL1261: Error importing OWBAssoc_CopyOf
Exception in thread "xxxx" java.lang.OutOfMemory Error: Java heap space


You may see these errors in the Design Center or in the Repository Assistant.
