(Doc ID 472181.1)

Last updated on OCTOBER 27, 2016

Applies to:

Oracle Net Services - Version: - Release: 9.2
z*OBSOLETE: Microsoft Windows Server 2003
Microsoft Windows Server 2003


While using 10gR2 or newer listener for any 10gR1 or older database, the issue described below might occur:

1. Handle count increases in oracle.exe but does not come down until restart of the database service.

2. tnslsnr.exe non-paged pool memory keeps increasing.

Handle count and non-paged memory use can be monitored from Windows Task Manager.


You are using a 10.2 or newer version of the listener to service any database version that is 10gR1 or older.
