Question

  • When should you increase shared memory on Nexus?
  • How can you do this?

Answer

When?

The shared memory has to be increased if you are encountering one of the following problems:

  • You're unable to restore or save Nexus workflows.
  • You're unable to see the jobs in the Nexus Manager Jobs window.
  • The jobs in the Nexus Manager Jobs window are not updated anymore.

How?

First, check if the IP Address is defined correctly.
To do so, follow the steps given below:

  1. Shut down Nexus.
  2. Go to the Nexus application folder and open NexusConfig or Nexus.env.
  3. Check if the IP Address is defined correctly.
  4. You need to increase the shared memory if:
    • The IP Address is not defined correctly.
    • The problem still occurs although you have corrected the IP Address.

To increase the shared memory on Nexus, follow the steps given below:

On Mac
  1. On system level, follow the instructions on http://www.spy-hill.net/help/apple/SharedMemory.html very strictly.
    Increase to 16MB, as described in the example.
  2. Shut Nexus down.
  3. Open Nexus.env in a text editor.
  4. Add the following lines or adjust them if they are already there:

    NexusSharedMemoryAddressMac=0x30000000
    
    NexusSharedMemoryNameMac=NEXS
    
    NexusSharedMemorySize=3145728

    You can copy these lines from NexusDefaults.env.

  5. Change the value of NexusSharedMemorySize to 6MB or 9MB.

  6. Re-launch Nexus.

On Windows
  1. Shut Nexus down.
  2. Open Nexus.env in a text editor.
  3. Add the following lines or adjust them if they are already there:

    NexusSharedMemoryNameMac=NEXS
    
    NexusSharedMemoryAddressWin=0x0E000000
    
    NexusSharedMemorySize=6291456

    You can copy these lines from NexusDefaults.env
