UNIX, Linux, and Mac OS X Client Agent Configuration For a Direct I/O backup or restore, you need to check the client environment and edit the caagperf.cfg configuration file. You can view Snapshot and Direct I/O on the file systems in the caagperf.cfg file by executing the mount command at the command line after submitting the backup or restore job. For Snapshot, the output that appears after executing the mount command is a new, read-only file system with the mount point starting with the prefix SNAP_HOME_ . A Direct I/O user can observe the changes in the mount options on that particular file system. You can also see the detailed messages in the caagperf.log file if you enabled the logging flag in the caagperf.cfg file. The following sections describe how to configure a UNIX client agent to use these features. 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 VERSION HOME ENV ENV ABagentux nn.nn.nn /opt/CA/uagent LD_LIBRARY_PATH=/usr/local/Calib:/opt/CA/ABcmagt 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.

Client Agents Guide
For a Direct I/O backup or restore, you need to check the client environment and
edit the caagperf.cfg configuration file. You can view Snapshot and Direct I/O on
the file systems in the caagperf.cfg file by executing the mount command at the
command line after submitting the backup or restore job.
For Snapshot, the output that appears after executing the mount command is a
new, read-only file system with the mount point starting with the prefix
SNAP_HOME_ . A Direct I/O user can observe the changes in the mount options
on that particular file system. You can also see the detailed messages in the
caagperf.log file if you enabled the logging flag in the caagperf.cfg file.
The following sections describe how to configure a UNIX client agent to use these
features.
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. See the next section for
detailed descriptions.
