Setting the Java memory size on 32-bit OS
H3C recommends using a 64-bit operating system when simultaneously deploying the IMC Platform and
service components.
When IMC runs on a 32-bit operating system, manually modify the assignable memory size of Java after
deployment using the following method:
1. Use a text editor (such as WordPad in Windows or vi in Linux) to edit the \client\bin\startup.bat
script or the startup.sh script on Linux.
2. Replace set JAVA_OPTS=-server –Xmx512m -Xrs -XX:PermSize=64m -XX:MaxPermSize=386m ...
with set JAVA_OPTS=-server -Xmx1024m -Xrs -XX:PermSize=64m -XX:MaxPermSize=576m ....
3. Save the file and restart the jserver process.
{
If the jserver process cannot start, decrease the above values until it can start.
{
If an out of memory error occurs after the jserver process starts, use a 64-bit operating system.
Installing IMC on a virtual machine
H3C recommends installing IMC on physical servers.
If IMC is installed on a virtual machine, do not change the following virtual machine configuration
settings:
• Number of CPUs
• Number, model, and MAC addresses of network adapters
• Number of disk drives, storage paths
• Assignments of storage
Although changing them does not affect VM migration, IMC will not operate correctly.

Preparing the installation environments
Uninstalling previous versions of IMC
If IMC was previously installed on the system, thoroughly remove it first. For instructions on removing IMC,
