12c: Listener Registration Issue: LREG Stops Providing Updates to Listener

(Doc ID 2402562.1)

Last updated on MAY 30, 2018

Applies to:

Oracle Net Services - Version and later
Information in this document applies to any platform.


LREG stops updating the listener.  The service may initially register but then over time, no updates occur.

This can result in any of the following errors:





The instance will reach its limit for connections. However, because LREG can no longer update the listener with load information, these errors may start to occur.


 This may occur after an upgrade, patchset application or change to sqlnet.ora file that resides in the same home where the listener runs.

Example, $GRID_HOME/network/admin/sqlnet.ora
