DESCRIPTION
You can use the oracle component to configure a custom monitor, or you
can use the default Oracle monitor that the Global Traffic Manager
provides. This type of monitor verifies services based on Oracle by
attempting to perform an Oracle login to a service.
EXAMPLES
create oracle my_oracle defaults-from oracle
Creates a monitor named my_oracle that inherits properties from the
default Oracle monitor.
list oracle
Displays the properties of all of the Oracle monitors.
OPTIONS
count
Specifies the number of instances for which the system keeps a
connection open. By default, when you assign instances of this
monitor to a resource, the system keeps the connection to the
database open. With this option you can assign multiple instances
to the database while reducing the overhead that multiple open
connections can cause.
A value of 0 (zero), the default, keeps the connection open for
all instances. A value of 1 opens a new connection for each
instance. Any other positive value keeps the connection open for
that many instances; for example, a value of 5 keeps the
connection open for five instances of this monitor.
database
Specifies the name of the database with which the monitor attempts
to communicate. The default value is none.
debug
Specifies whether the monitor sends error messages and additional
information to a log file created and labeled specifically for
this monitor. You can use the log information to help diagnose and
troubleshoot unsuccessful health checks. The default value is no.
The options are:
no Specifies that the system does not redirect error messages
and additional information related to this monitor.
yes Specifies that the system redirects error messages and
additional information to the
/var/log/monitors/--.log file.
defaults-from
Specifies the name of the monitor from which you want your custom
monitor to inherit settings. The default value is oracle.
description
User defined description.
destination
Specifies the IP address and service port of the resource that is
the destination of this monitor. The default value is *:*.
Possible values are:
*:* Specifies to perform a health check on the IP address and
port supplied by a pool member.
*:port
Specifies to perform a health check on the server with the IP
address supplied by the pool member and the port you specify.
IP address:port
Specifies to mark a pool member up or down based on the
response of the server at the IP address and port you
specify.
glob Displays the items that match the glob expression. See help glob
for a description of glob expression syntax.
ignore-down-response
Specifies whether the monitor ignores a down response from the
system it is monitoring. The default value is disabled.
interval
Specifies the frequency at which the system issues the monitor
check. The default value is 30 seconds.
name Specifies a unique name for the component. This option is required
for the commands create, delete, and modify.
partition
Displays the administrative partition within which the component
resides.
password
Specifies the password if the monitored target requires
authentication. The default value is none.
probe-timeout
Specifies the number of seconds after which the BIG-IP(r) system
times out the probe request to the BIG-IP system. The default
value is 5 seconds.
recv Specifies the text string that the monitor looks for in the
returned resource. The default value is none.
The most common receive expressions contain a text string that is
included in a field in your database. If you do not specify a
value for both the send and recv options, the monitor performs a
simple service check and connect only.
recv-column
Specifies the column in the database where the system expects the
specified Receive String to be located. Specify this option only
if you configure the send and recv options. The default value is
none.
recv-row
Specifies the row in the database where the system expects the
specified Receive String to be located. Specify this option only
if you configure the send and recv options. The default value is
none.
regex
Displays the items that match the regular expression. The regular
expression must be preceded by an at sign (@[regular expression])
to indicate that the identifier is a regular expression. See help
regex for a description of regular expression syntax.
send Specifies the SQL query that the monitor sends to the target
database, for example, SELECT count(*) FROM mytable.
If this value is null, then a valid connection suffices to
determine that the service is up. In this case, the system does
not need the recv option and ignores the option even if not null.
timeout
Specifies the number of seconds the target has in which to respond
to the monitor request. The default value is 91 seconds.
If the target responds within the set time period, it is
considered up. If the target does not respond within the set time
period, it is considered down. Also, if the target responds with a
RESET packet, the system immediately flags the target as down
without waiting for the timeout interval to expire.
username
Specifies the username, if the monitored target requires
authentication. The default value is none.
