Configuring core group socket buffers

Most operating systems provide program interfaces for performing operations involving the sending and receiving of data over sockets. Most operating systems also provide administrative capabilities to control the amount of memory allocated per socket that is used as data buffers.

 

Before you begin

 

About this task

You might want to change the size of your core group buffers in the following circumstances:

To change the socket buffer space that the core group transport allocates:

 

Procedure

  1. In the administrative console, click Servers > Core groups > Core group settings > core_group_name.

  2. Under Additional Properties, click Custom Properties.

  3. Change the value that is specified for the IBM_CS_SOCKET_BUFFER_SIZE custom property.

    If the IBM_CS_SOCKET_BUFFER_SIZE property already exists, click the property name and specify either 0, 1, 2, or 3.

    If this property does not already exist, click New and create it:

    1. In the Name field, specify IBM_CS_SOCKET_BUFFER_SIZE.

      • 3

  4. Click OK, and then click Save to save your changes.

  5. Select Synchronize changes with nodes, and then click Save again.

  6. Restart all members of the core group.

 

Results

After the servers restart, the core group members all run with the new socket buffer size settings.
