Reading a file line by line and processing for each line
Hi,
I am a beginner in shell scripting. I have written the following script, which is supposed to process the while loop for each line in the sid_home.txt file. But I'm getting the 'end of file' unexpected for the last line. The file sid_home.txt gets generated as expected, but the script doesn't execute the instructions in the while loop:
#!/bin/ksh
cd /home/dba/utils/scripts/monitor
sed '/^#.*$/d' /var/opt/oracle/oratab | sed '/^[Cc]lient.*$/d' | sed '/^CRS.*$/d' | awk -F: '{print$1, $2;}' > sid_home.txt
{ while read LINE;do
ORACLE_SID=`awk '{print $1;}' $LINE`; export ORACLE_SID
ORACLE_HOME=`awk '{print $2;}' $LINE`; export ORACLE_HOME
DATE_TIME=`date +%m%d%y%a_%H%M`; export DATE_TIME
TSPALERT_LOG=tspalert_${ORACLE_SID}_${DATE_TIME}.log;export TSPALERTLOG
ORACLE_BASE=${ORACLE_HOME}; export ORACLE_BASE
ORACLE_BIN=${ORACLE_HOME}/bin; export ORACLE_BIN
LD_LIBRARY_PATH=/usr/openv/netbackup/bin:/usr/dt/lib:/usr/openwin/lib:/usr/local/lib:${ORACLE_HOME}/lib32
LD_LIBRARY_PATH_64=${ORACLE_HOME}/lib
ORACLE_DOC=${ORACLE_HOME}/orainst/doc
${ORACLE_HOME}/bin/sqlplus -s /nolog << EOF
set heading off
spool $TSPALERT_LOG;
select name from v$database;
select to_char(sysdate,'DD-MM-YYYY HH24:MI:SS') from dual;
select tablespace_name,sum(bytes)/1048576 MBUsed, sum(maxbytes)/1048576 TotalMB, sum(bytes)/sum(maxbytes)*100 PercentUsed
from dba_data_files
group by tablespace_name
having sum(bytes)/sum(maxbytes)*100 >= 80;
spool off
EXIT;
EOF
if [ -f ${TSPALERT_LOG} ]; then
echo "**ERROR**: TABLESPACE NEARLY FULL OR NOT ENOUGH ROOM FOR THE NEXT EXTENT IN ${ORACLE_SID}. Check log ${TSPALERT_LOG} " > /dev/null
mv ${TSPALERT_LOG} ${TSPALERT_LOG}.old > /dev/null
fi
done } < sid_home.txt

Take a variable such as ROW-D-01, compare it to what's in one line in the text file such as PROD/VM/ROW-D-01 and only input PROD/VM into a variable without the /ROW-D-01.
Is this possible? any help is appreciated. (2 Replies)

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 | 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. .sp 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. .sp Three settings are possible: .sp - 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) .sp 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. .sp 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: .sp alter system checkpoint; shutdown
abort; .sp 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 .sp shutdown immediate; .sp 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)
