OCF_HEARTBEAT_ORACLE(7) OCF resource agents OCF_HEARTBEAT_ORACLE(7)NAMEocf_heartbeat_oracle - Manages an Oracle Database instance
SYNOPSIS
oracle [start | stop | status | monitor | meta-data | validate-all]
DESCRIPTION
Resource script for oracle. Manages an Oracle Database instance as an
HA resource.
SUPPORTED PARAMETERS
sid
The Oracle SID (aka ORACLE_SID).
(unique, required, string, no default)
home
The Oracle home directory (aka ORACLE_HOME). If not specified, then
the SID along with its home should be listed in /etc/oratab.
(optional, string, no default)
user
The Oracle owner (aka ORACLE_OWNER). If not specified, then it is
set to the owner of file $ORACLE_HOME/dbs/*${ORACLE_SID}.ora. If
this does not work for you, just set it explicitely.
(optional, string, no default)
ipcrm
Sometimes IPC objects (shared memory segments and semaphores)
belonging to an Oracle instance might be left behind which prevents
the instance from starting. It is not easy to figure out which
shared segments belong to which instance, in particular when more
instances are running as same user.
What we use here is the "oradebug" feature and its "ipc" trace
utility. It is not optimal to parse the debugging information, but
I am not aware of any other way to find out about the IPC
information. In case the format or wording of the trace report
changes, parsing might fail. There are some precautions, however,
to prevent stepping on other peoples toes. There is also a
dumpinstipc option which will make us print the IPC objects which
belong to the instance. Use it to see if we parse the trace file
correctly.
Three settings are possible:
- none: don't mess with IPC and hope for the best (beware: you'll
probably be out of luck, sooner or later)
- instance: try to figure out the IPC stuff which belongs to the
instance and remove only those (default; should be safe)
- orauser: remove all IPC belonging to the user which runs the
instance (don't use this if you run more than one instance as same
user or if other apps running as this user use IPC)
The default setting "instance" should be safe to use, but in that
case we cannot guarantee that the instance will start. In case IPC
objects were already left around, because, for instance, someone
mercilessly killing Oracle processes, there is no way any more to
find out which IPC objects should be removed. In that case, human
intervention is necessary, and probably _all_ instances running as
same user will have to be stopped. The third setting, "orauser",
guarantees IPC objects removal, but it does that based only on IPC
objects ownership, so you should use that only if every instance
runs as separate user.
Please report any problems. Suggestions/fixes welcome.
(optional, string, default "instance")
clear_backupmode
The clear of the backup mode of ORACLE.
(optional, boolean, default false)
shutdown_method
How to stop Oracle is a matter of taste it seems. The default
method ("checkpoint/abort") is:
alter system checkpoint; shutdown abort;
This should be the fastest safe way bring the instance down. If you
find "shutdown abort" distasteful, set this attribute to
"immediate" in which case we will
shutdown immediate;
If you still think that there's even better way to shutdown an
Oracle instance we are willing to listen.
(optional, string, default "checkpoint/abort")
SUPPORTED ACTIONS
This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 120.
stop
Stops the resource. Suggested minimum timeout: 120.
status
Performs a status check. Suggested minimum timeout: 5.
monitor
Performs a detailed status check. Suggested minimum timeout: 30.
Suggested interval: 120.
validate-all
Performs a validation of the resource configuration. Suggested
minimum timeout: 5.
methods
Suggested minimum timeout: 5.
meta-data
Retrieves resource agent metadata (internal use only). Suggested
minimum timeout: 5.
EXAMPLE
The following is an example configuration for a oracle resource using
the crm(8) shell:
primitive p_oracle ocf:heartbeat:oracle \
params \
sid=string \
op monitor depth="0" timeout="30" interval="120"
