I have a table with one row. There is an XML column in the table. Selecting a count(*) returns 1 as expected.
Running select * from the table hangs toad for quite some time, the throbber is throbbing and if I cancel the query and it will eventually cancel but displays an error dialog containing “ORA-21527: internal OMS driver error”.
If I don’t cancel the query, it will eventually return, but there are no results and the same error dialogue appears.
The table is the usual mix of VARCHAR2, NUMBER, there’s a CLOB and one of these:
) STORAGE Object-relational
I can easily access the data from SQL*Plus on the server and on my local desktop too, so it looks to be a Toad problem, I think. There’s almost nothing on “My Oracle (lack of) Support” other than a fix in Oracle 10g for something that is not related, but gave the same error code.
I have a trace file which I ran to trace the problem, and surprisingly enough, it doesn’t actually report the error - which Toad does. There’s nothing in the trace at all, and the FETCH shows that one row was retrieved, but it never arrived at Toad. The trace file has no confidential or sensitive information in it, so I can supply it if required.
