extend temp segment by 314 in tablespace TEMP. I understand the ORA-01652 as being caused by running out of space, but I do not understand the ORA-12801.

You can set event 10397 to get more details: ORA-12801, 00000, "error signaled in parallel query server %s" Cause: A parallel query server reached an exception condition.
