I am running ORACLE 8i database. I start DBA studio and want to use backup manager. but when i click on this item a message appears that shows that you can only use this option when ORACLE Management Server is running. i configured the OMS and start it. but when i want to logon to Management Server an error message appers "EMSDK-1100 unable to make a secure communication channel".
Pl briefly describe , what should i do more to logon to OMS and ulmitely use backup manager in DBA studio.
-------------------
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.d
e.g. to:
%ORACLE_HOME%\bin\njssl8_o
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.d
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
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.d
j. Copy the extracted file (see h.) to %ORACLE_HOME%\bin\njssl8.d
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.
Current planning is that the problem will be fixed in the 8.1.7.3 patch-set
(planned release-date: January/February 2002).
Explanation
-----------
In the 8.1.7.2.1 Patch Set, one of the modified DLL's is:
%ORACLE_HOME%\bin\njssl8.d
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.
