also specify the space monitoring and alarm information for each file system, tablespace, and
datafile. You can edit these files manually to change settings, and then restart the Monitoring
Agent.
The Monitoring Agent uses the /etc/vx/vxdba/$ORACLE_SID/include file to check that
all files are up-to-date and are being monitored. This file is created by VERITAS Storage
Foundation for Oracle and should not be edited.
Occasionally, Monitoring Agents ignore Storage Checkpoints. This happens when a Storage
Checkpoint is not owned by the current Oracle instance. These Storage Checkpoints will not be
used to calculate thresholds and potential removal candidates. Storage Checkpoints that are not
considered part of the current database instance's data set are logged as such in the file
/var/log/dbed_mon/dbed_mon.prune_ckpt_log.$ORACLE_SID
when the
Monitoring Agent is looking for potential removal candidates. A Storage Checkpoint must have an
entry in the /etc/vx/vxdba/$ORACLE_SID/checkpoint_dir directory before it is
considered owned by the database. This is done automatically by the provided VxDBA(1M) and
dbed_ckptcreate(1M) utilities and ensures that, if multiple databases share the same file
system(s), the policy for one database does not affect another.
