Please see the following: How do I find distributed queries / transactions (either issued from or connecting to this instance)? http://www.jlcomp.demon.co.uk/faq/find_dist.html ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Roger Xu Sent: Friday, January 22, 2010 5:01 PM To: oracle-l@xxxxxxxxxxxxx Subject: ORA-02020: too many database links in use We are getting this error and I know I need to increase open_links parameter which requires recycling the instance. My question is - how to find out all open dblinks so I can kill some sessions which are holding dblinks? (V$DBLINK lists all open database links in the current session.) Thanks, Roger
