Setting System Environment Variables on AIX

Setting System Environment Variables on AIX

When you configure the PowerCenter Integration Service to run on AIX and you install the WebSphere MQ server driver, set the memory address space layout to allow the IPC segment to allocate memory for the PowerCenter Integration Service.
To set system environment variables on AIX:
  1. Set the LDR_CNTRL system environment variable to MAXDATA=0x60000000 for the PowerCenter Integration Service.
    In a C shell environment, type: 
    setenv LDR_CNTRL MAXDATA=0x60000000
    In a Bourne shell environment, type: 
    LDR_CNTRL = “MAXDATA=0x60000000”; export LDR_CNTRL
  2. Stop the WebSphere MQ queue manager.
  3. Set the IPCCBaseAddress address parameter in the mqs.ini file to reallocate system memory for WebSphere MQ.
  4. Enter 11 for the IPCCBaseAddress parameter in the mqs.ini file to reallocate system memory for WebSphere MQ. For example, enter: 
    IPCCBaseAddress=11
