A rather simple way to monitor socket activity (aka streams), especially for blockage is to look at netstat -tn output.
What you are looking for is numbers in the Send-Q and/or Recv-Q. If they are consistently at the sendspace/recvspace size then you may be suffering from network congestion outside the box - as TCP is doing what it can, then stopping and waiting for acknowledgements (Send-Q at max) and the "outside" is waiting for the server to wake up and respond when the Revc-Q is "stuck" at max.
I have looked at netstat -nm again. It is normal that there are some "delayed" numbers. Not sure why - probably has something to do with setting up the stack. What you want to watch for is "failed" - as that indicates, mainly, not enough memory for communications.
Question: as this sometimes occurs: are you using large sends (e.g., MTU of 9000) while the network and/or endpoints cannot support that?

ocf_heartbeat_oracle
OCF_HEARTBEAT_ORACLE(7) OCF resource agents OCF_HEARTBEAT_ORACLE(7)NAME
ocf_heartbeat_oracle - Manages an Oracle Database instance
SYNOPSIS
oracle [start | stop | status | monitor | validate-all | methods | meta-data]
DESCRIPTION
Resource script for oracle. Manages an Oracle Database instance as an HA resource.
SUPPORTED PARAMETERS
sid
The Oracle SID (aka ORACLE_SID). (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 example_oracle ocf:heartbeat:oracle
