DYNAMIC_REGISTRATION_<listener> is a part of listener feature changes (including COST) that were added to (from what I've read) and above but not included in the doc under 11g.

Thanks Carol, but the dynamic_registration_listener_name parameter appears to be undocumented in 10g (as far as I could tell) and therefore may not be fully supported. I found it here in the 11.2 doc:

But, couldn't find it anywhere in the 10.2 doc. I also found MOS doc 130574.1, which suggests using the dynamic_registration_listener_name parameter only in 11g and up and says that dynamic registration "can't be disabled in versions 10g and lower from the listener side". I haven't tested it myself yet, but from your info below, it sounds like the parameter does work in 10g, or are your 10g databases only using 11g listeners?

*THE FOLLOWING IS NOT APPLICABLE FOR RAC* - only single instance Oracle databases

This is what we are doing to protect our 10g and 11g versions of the listener before we can apply the workaround described in the CVE_2012_1675.


  1. Save listener.ora file to listener.ora.OLD1
  2. Edit the listener.ora file by putting in DYNAMIC_REGISTRATION_<NAME_OF_LISTENER> = OFF
