tail -XXX with grep doesn't work in while loop
Hi all,

I need some help. my shell script doesn't work especially in the loop.

Code:
#!/bin/sh -xv

export ORA_ADMIN=/oracle/home/admin
export ORACLE_SID=ORA_SID
cat ${ORA_ADMIN}/param_alert_log.ora | while read MSG
do
  #echo $MSG
  #echo "tail -400 ${ORA_ADMIN}/${ORACLE_SID}/bdump/alert_${ORACLE_SID}.log \| grep $MSG"
  tail -400 ${ORA_ADMIN}/${ORACLE_SID}/bdump/alert_${ORACLE_SID}.log | grep $MSG >> /tmp/ora600_${ORACLE_SID}.ora
  #echo "Retour val : $?"
done

check_stat=`cat /tmp/ora600_${ORACLE_SID}.ora|wc -l`;
oracle_num=`expr $check_stat`
if [ $oracle_num -ne 0 ]
then
   newm=`diff /tmp/ora600_${ORACLE_SID}.ora /tmp/ora600_${ORACLE_SID}.old|wc -l`
   chgflg=`expr $newm`
   if [ $chgflg -ne 0 ]
   then
      cat /tmp/ora600_${ORACLE_SID}.ora | mailx -s "$ORACLE_SID : alerte(s) ORA- detectee(s)" admin@XXX.fr
      echo "envoi mail"
   fi
fi

cp /tmp/ora600_${ORACLE_SID}.ora /tmp/ora600_${ORACLE_SID}.old
rm -f /tmp/ora600_${ORACLE_SID}.ora


Many thanks for help

Best regards

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 
	     params 
	       sid=string 
	     op monitor depth="0" timeout="30" interval="120"
