Emsdk-1100 error with OEM Console...

Question

I've installed Oracle 8.1.7.0.0 on Windows 2000.
The OEM worked fine.
But after applying the 8.1.7.2.1 patchset,
I got the error 'Emsdk-1100:unable to etablish a secure
communication channel' every time I tried to bring up the console
(connected as SYSMAN).
Any help is highly appreciated.

Answer 1

The following fix from Metalink solved this problem for me.
Problem Description
1. When trying to start the OEM Console or one of the Management
Pack
utilities (e.g. DBA-Studio or one of the other Managers), you
get
the following error:
EMSDK-1100: Unable to establish a secure communication
channel.
and the program will not start. When starting the Management
Pack
utilities in the standalone mode, this error does not occur.
2. This problem occurs:
- after the installation of the 8.1.7.2.1 Patch Set on top of
either
8.1.7.0.0 or 8.1.7.1.x
- on the platform Microsoft Windows NT or Windows 2000
- when on the same machine, in the same %ORACLE_HOME%, the
Oracle Enterprise Manager (OEM) utilities release 2.2 are
installed
(e.g. the OEM Console and one or more Management Packs),
and
the Oracle Management Server (OMS) release 2.2.
Solution Description
1. Before applying the Patch Set 8.1.7.2.1, rename the file
%ORACLE_HOME%\bin\njssl8.dll
e.g. to:
%ORACLE_HOME%\bin\njssl8_old.dll
After applying the patch-set 8.1.7.2.1,
-> rename the new njssl8.dll (causing problem) to
njss8_new.dll
-> rename old njssl8_old.dll (good version) to njssl8.dll
Start the OMS (or reboot the machine and re-start the OMS).
2. When no backup of %ORACLE_HOME%\bin\njssl8.dll has been made
before
installing the 8.1.7.2.1 patch-set, obtain the latest earlier
version
of this DLL. This file can be found in the 8.1.7.1.1 patch-
set which
can be downloaded via MetaLink:
a. Run WinZip to open the 81711 patch-file:
p1711240_8171_WINNT.zip
b. Double-click on the file: WinNT-81711_patchset.exe
and choose "Run WinZip" in the "WinZIP Self-Extractor"
screen.
c. In the new WinZip screen, locate the file: lib.0.4.jar
Note: there exist 4 (four) files with the name lib.0.4.jar
Choose the one which will be extracted to the location:
81711\stage\Patches\oracle.options.ano.ssl\8.1.7.1.1\1
\DataFiles\
d. Extract this file to disk.
e. Locate the file lib.0.4.jar which was extracted to disk
f. Open this JAR file with WinZip.
g. The JAR file contains one file only: njssl8.dll
h. Extract this file to disk in a temporary directory.
i. Rename %ORACLE_HOME%\bin\njssl8.dll to %ORACLE_HOME%
\bin\njss8_new.dll
j. Copy the extracted file (see h.) to %ORACLE_HOME%
\bin\njssl8.dll
k. Start the OMS (or reboot the machine and re-start the OMS).
3. A fix for this problem is not implemented in the 8.1.7.2.x
patch-set.
Consult [BUG:1946984] in order to find out if a patch is
available.
Explanation
In the 8.1.7.2.1 Patch Set, one of the modified DLL's is:
%ORACLE_HOME%\bin\njssl8.dll
This DLL is also used during the startup of the OEM Console or
the
Management Pack utilities which login to the Oracle Management
Server
(i.e. which are using the OEM Repository).
The new version of this DLL, shipped with patch-set 8.1.7.2.1 on
the
Windows platform, causes a Secure Communication Error, resulting
in the:
EMSDK-1100: Unable to establish a secure communication
channel.
