UNIX, Linux, and Mac OS X Client Agent Configuration File
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/BABcmagt directory.
After you enable this environment variable, the client agent section of the
agent.cfg file looks like this:
[0]
NAME BABagentux
VERSION nn.nn.nn
HOME /opt/uagent
ENV LD_LIBRARY_PATH=/usr/local/Calib:/opt/CA/BABcmagt
ENV CAAGPERF_ENABLE=1
2. Prepare the configuration file named caagperf.cfg in the
/opt/CA/BABcmagt 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.
