Last updated on JULY 17, 2017
Applies to:Oracle Database - Enterprise Edition - Version 220.127.116.11 and later
Oracle Database Gateway for SQL Server - Version 18.104.22.168 and later
Microsoft Windows x64 (64-bit)
After configuring or modifying an Oracle Database Gateway listener such as DG4MSQL or DG4ODBC, attempts to start the listener hang.
The following message is displayed in the listener log -
type='UNKNOWN' level='16' host_id='some ID'
<txt>Dynamic address is already listened on (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=hostname)(PORT=1521)))
The listener was previously configured and working but was then modified to add additional SIDs or to change the listener port.
