When I uninstall IMC in distributed mode from the master server, the component data in the Oracle
database cannot be deleted. Why?
This is because the data is used by other users that IMC cannot drop.
Restart the operating system or the Oracle database.
How to install the Java running environment on Linux so that I can access IMC properly through Firefox?
To install the Java running environment, install JDK or JRE and configure JDK or JRE for Firefox. JDK is
taken for example in the following part.
1. Download JDK
Address: http://www.oracle.com/technetwork/java/javase/downloads/index.html
Make sure the correct version is downloaded. For example: you must download
jdk-6u12-linux-i586-rpm.bin for x86-based Linux.
2. Install JDK
Upload the installation file jdk-6u12-linux-i586-rpm.bin to the server. Suppose the installation file is saved
in directory /tmp, execute the following commands:
cd /tmp
sh jdk-6u12-linux-i586-rpm.bin
After executing the commands above, press the Space bar to view the copyright information, and then
enter yes to finish the JDK installation.
Thus, JDK is installed in directory /usr/java/jdk1.6.0_12. At the same time, a link /usr/java/default
pointing the directory /usr/java/jdk1.6.0_12 is generated automatically, equivalent to JDK is installed in
directory /usr/java/default.
3. Configure JDK for Firefox
On the Linux operating system, execute the following commands:
cd /var/local/firefox/plugins/
ln -s /usr/java/default/jre/plugin/i386/ns7/libjavaplugin_oji.so
After executing the commands above, you can run /var/local/firefox/firefox to access IMC.
In Linux, the current system time in IMC (such as the login time and operation log record time) is different
from that on the server, and the difference may be several hours. How to solve the problem?
This is because the current time zone setting on the server is different from that when IMC was installed.
You can use the tzselect command to modify the time zone of the server.
After IMC is installed in the Windows Server 2003 64-bit edition, the IMC background processes cannot
be started. How to solve the problem?
Before installing IMC in Windows Server 2003 64-bit OS, you must first install the
WindowsServer2003-KB942288-v4-x64.exe patch. Otherwise, part of IMC processes cannot start after
installation and deployment.
To solve this problem, stop IMC, install the patch mentioned above, and manually execute IMC
installation path\deploy\components\server\vcredist.exe.
