Chapter 2: Operations 13

The following parameters can be set in the configuration file.

Logging

The probes and monitors provided with MxDB-Oracle-HiAv send

logging output to two locations. On each node, MxDB-Oracle-HiAv sends

start/stop/recovery and probe logging information to a non-CFS

directory. However, to aid in administration, it also sends log messages to

a central log in the PolyServe cluster filesystem.

The system-level logs are placed in /var/log/polyserve and are named

SPACK_ORACLE.<DBNAME>-<type>.log, where DBNAME is the name that

was specified when the Virtual Oracle Service was created. type is either

start, stop, recovery, or probe. Generally, these logs are used only by

PolyServe Technical Support.

The central log is placed in

$ORACLE_BASE/admin under the

DBNAME>/bdump subdirectory. The DBA can override this logging

location by setting the log parameter in the MxDB-Oracle-HiAv

configuration file. For example:

$ cat $ORACLE_HOME/dbs/mxdbha_PROD.conf

log /u01/app/oracle/product/9.2.0/rdbms/log
