ORA-20000: Oracle Text error:
DRG-10502: index WWSBR_CORNER_CTX_INDX does not exist
We opened a Service Request at Oracle support but never figured out how the index disappeared, if that was the case and not a corruption somewhere. Support suggested that we executed the procedure given in Doc ID 340439.1; reinstall Oracle Text, then connect as the portal user from Portal server and execute the three scripts from middle tier home:
@?/portal/admin/plsql/wws/ctxdrind.sql
@?/portal/admin/plsql/wws/inctxgrn.sql
@?/portal/admin/plsql/wws/ctxcrind.sql
But the last script failed with:
SQL> @?/portal/admin/plsql/wws/ctxcrind.sql
Creating Context Preferences and Indexes...
PL/SQL procedure successfully completed.

The Application Server Portal Configuration Guide section 8.3.4.1 shows that the last script executes wwv_context.createindex and the error was isolated first to this procedure. The same section shows that wwv_context.createindex is equivalent to:
wwv_context.drop_prefs; /* Drop all Oracle Text preferences for the indexes, except Lexer preferences */
wwv_context.drop_invalid_indexes; /* Drop all invalid indexes */
wwv_context.create_prefs; /* Create all Oracle Text preferences,except Lexer preferences */
wwv_context.create_missing_indexes(l_indexes); /* Create missing indexes and record them in l_indexes */
wwv_context.touch_index(l_indexes); /* Mark all rows for created indexes as requiring synchronization */
wwv_context.sync; /* Synchronize indexes */
wwv_context.optimize; /* Optimize indexes */
By executing each procedure in steps the error was isolated to wwv_context.create_missing_indexes. All of the indexes in question are listed in 8.3.4.2 and can be created one by one with procedure wwv_context.create_index.
To get around the error I executed the following procedure in stead of the script ctxcrind.sql, that is, after I executed the scripts inctxgrn.sql and ctxcrind.sql:
EXEC WWV_CONTEXT.CREATE_PREFS
EXEC WWV_CONTEXT.CREATE_INDEX(WWV_CONTEXT.PAGE_TEXT_INDEX)
EXEC WWV_CONTEXT.CREATE_INDEX(WWV_CONTEXT.DOC_TEXT_INDEX)
exec WWV_CONTEXT.CREATE_INDEX(wwv_context.PERSPECTIVE_TEXT_INDEX)
EXEC WWV_CONTEXT.CREATE_INDEX(WWV_CONTEXT.ITEM_TEXT_INDEX)
EXEC WWV_CONTEXT.CREATE_INDEX(WWV_CONTEXT.CATEGORY_TEXT_INDEX)
EXEC WWV_CONTEXT.CREATE_INDEX(WWV_CONTEXT.URL_TEXT_INDEX)
EXEC WWV_CONTEXT.TOUCH_INDEX(WWV_CONTEXT.PAGE_TEXT_INDEX)
EXEC WWV_CONTEXT.TOUCH_INDEX(WWV_CONTEXT.DOC_TEXT_INDEX)
EXEC WWV_CONTEXT.TOUCH_INDEX(WWV_CONTEXT.PERSPECTIVE_TEXT_INDEX)
EXEC WWV_CONTEXT.TOUCH_INDEX(WWV_CONTEXT.ITEM_TEXT_INDEX)
EXEC WWV_CONTEXT.TOUCH_INDEX(WWV_CONTEXT.CATEGORY_TEXT_INDEX)
exec wwv_context.touch_index(WWV_CONTEXT.URL_TEXT_INDEX)
exec wwv_context.sync;
exec wwv_context.optimize;
We did not verified if it was really necessary to reinstall Oracle Text, you may try the procedure above before reinstall Oracle Text if you encounter the same error with wwv_context.sync.
