Creating a Text Index with USER_DATASTORE Shows Error DRG-50857, ORA-22920 in CTX_USER_INDEX_ERRORS (Doc ID 1110326.1)

Last updated on JANUARY 05, 2020

Applies to:

Oracle Text - Version 10.2.0.1 to 11.2.0.3 [Release 10.2 to 11.2]
Information in this document applies to any platform.

Symptoms

Creating a domain index with a user_datastore procedure that returns a CLOB fails to index the document with the following errors:

DRG-50857: oracle error in drsinopen
ORA-22920: row containing the LOB value is not locked

When using the FOR UPDATE clause to lock the CLOB, indexing succeeds, but the CLOB in the table disappears (seems to be an empty CLOB).
