arcserve-KB : arcserve D2D web service on arcserve D2D systems runs slowly.

Last Update: 2015-12-15 22:19:33 UTC

Description:

The CA ARCserve D2D web service on CA ARCserve D2D systems runs slowly. You can detect other symptoms such as:

  • The CA ARCserve D2D web service stops responding or occupies 100 percent of the CPU resources.
  • CA ARCserve D2D nodes perform poorly or cannot communicate with the web service.

Solution:

In various environmental configurations, you can discover that the CA ARCserve D2D web service occupies too much CPU time, or the response is slow. By default, Tomcat is configured to allocate a limited amount of memory to the nodes, which may not be suitable for your environment. To verify this problem, review the following log files:


<D2D_home>\TOMCAT\logs\casad2dwebsvc-stdout.*.log

<D2D_home>\TOMCAT\logs\casad2dwebsvc-stder.*.log

<D2D_home>\TOMCAT\logs\catalina.*.log

<D2D_home>\TOMCAT\logs\localhost.*.log

Search for the following message:


java.lang.OutOfMemoryError 

To correct this problem, increase the amount of allocated memory.

To increase the memory, do the following:

  1. Open Registry Editor and access the following key:
    • x86 Operating Systems:
      
      HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Procrun 2.0\CASAD2DWebSvc\Parameters\Java
      
      
    • x64 Operating Systems:
      
      HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\CASAD2DWebSvc\Parameters\Java
      
      
  2. Do one of the following:
    • If the message in the log file is the following:
      
      java.lang.OutOfMemoryError: PermGen space
      
      

      Append the following to the value of Options.

      
      -XX:PermSize=128M -XX:MaxPermSize=128M
      
      

      Note: You may need to increase the value of -XX:MaxPermSize to suit your environment.

    • If the message in the log file is one of the following:
      
      java.lang.OutOfMemoryError: Java heap space
      
      java.lang.OutOfMemoryError: GC overhead limit exceeded
      
      

      Increase the value of the following DWORD:

      
      JvmMx
      
      
  3. Restart the CA ARCserve D2D web service.
