What is the POBS eraser tool?


The POBS eraser tool reads XER files, removes the POBS section andthen generates new XER files to a folder specified by user.
For information about the POBS table please refer to KMArticle: What is the POBS Table Used for and What Data is Stored in POBS? (Doc ID1959228.1).


Please note that the tool simply finds the beginning andend of the POBS section in a fixed format. It may fail to recognize thebeginning or end due to bad formatting such as extra spaces caused by manualedit or 3rd party tools.



In which cases should we use the tool?


  • when an error occurs when trying to import an XER file, as described in KMnote:  Error Importing XER: ORA-12899: value too large for column"ADMUSER"."POBS"."POBS_NAME" (Doc ID1681756.1).
  • when the POBS section of an exported project is large and causes importperformance issue.
