3.1 In Linux Platform, iManager is Displaying a Blank Page After Upgrade

Issue: After upgrading to Identity Manager 4.8.7, iManager will no longer work if installed with other components. When you try to launch a previously installed version, iManager displays a blank page.

Workaround: NetIQ recommends that you install and use Identity Console in place of iManager. However, if you want to continue using iManager, you must consider the following important points before upgrading Identity Manager to version 4.8.7:

On the server where iManager is installed, make sure it has the supported version of Java. For example, Java JDK 1.0.8 Update 342 for iManager 3.2.6.0200.

In addition, follow the procedure below to reuse the existing Java files:
1. Create a new directory using the following command:
```
mkdir -p /opt/novell/iManager/java_iman
```
2. Copy the existing Java files of iManager to the new directory:
```
cp -r /opt/netiq/common/jre/ /opt/novell/iManager/java_iman
```
3. To change the ownership to the new directory, run the following command:
```
chown -R novlwww:novlwww /opt/novell/iManager/java_iman 
```
4. Navigate to /etc/opt/novell/tomcat9/ and update the JAVA_HOME and JRE_HOME with the new Java path in the tomcat9.conf file. For example, in tomcat9.conf replace:
  
  JAVA_HOME="/opt/netiq/common/jre"
  
  JRE_HOME="/opt/netiq/common/jre"
  
  with
```
JAVA_HOME="/opt/novell/iManager/java_iman/jre"
JRE_HOME="/opt/novell/iManager/java_iman/jre"
```
5. Restart Tomcat using the following comment:
```
rcnovell-tomcat9 restart
```
Make sure that iManager is installed on a standalone server.
