Configure Snapshot and Direct I/O

To configure the Snapshot and Direct I/O features, follow these steps:

  1. Enable the environment variable CAAGPERF_ENABLE by adding the following line in the agent.cfg file: 
    ENV CAAGPERF_ENABLE=1

    Note: The agent.cfg file is in the /opt/CA/ABcmagt directory.

    After you enable this environment variable, the client agent section of the agent.cfg file looks like this:

    [0]
NAME		ABagentux
VERSION		nn.nn.nn
HOME		/opt/CA/uagent
ENV			LD_LIBRARY_PATH=/usr/local/Calib:/opt/CA/ABcmagt
ENV			CAAGPERF_ENABLE=1
  2. Prepare the configuration file named caagperf.cfg in the /opt/CA/ABcmagt directory. You need to specify the types of operations to be completed on the specified file systems in the caagperf.cfg file.
