Hi,

that's perfect, thanks.

However is it possible to only capture that particular day's errors. So for example this will be run on a daily basis, say 3am and I would like the ORA error message for only the previous day. Is this possible?

Many thanks for your assistance

Yes, this is for Linux (or any other system that has the GNU date installed):

Code:
#!/bin/bash


ORACLE_HOME=<your_oracle_home>
ORACLE_SID=<your_oracle_sid>
ORAENV_ASK=NO
export ORACLE_HOME ORACLE_SID ORAENV_ASK

_mailto=<your_email_address>
_mail_subject="Alert for $ORACLE_SID on $HOSTNAME"
_today=$(
  date '+%Y-%m-%d 00:00:00'
  )
_yesterday=$(
  date -d yesterday +'%Y-%m-%d 00:00:00'
  )  

_my_result=$(
  adrci exec="
    set home $ORACLE_SID;
    show alert -term -P \\\"MESSAGE_TEXT like '%ORA%' and ORIGINATING_TIMESTAMP between '$_yesterday' and '$_today'\\\"
   "
  )

case $_my_result in 
  ( *ORA-* ) mailx -s "$_mail_subject" "$_mailto" <<< "$_my_result"  
esac

Thanks for that - now when I execute the script nothing happens.
I would like to capture the script to see what happens but if I execute file.sh > file.log the log file is empty

This is the script you sent me with the 3 necessary changes in bold. Any suggestions?


Code:
[oracle@ukedxdtmtdbs01a scripts]$ more test.sh
#!/bin/bash


ORACLE_HOME=ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
ORACLE_SID=DCTMTEST1
ORAENV_ASK=NO
export ORACLE_HOME ORACLE_SID ORAENV_ASK

_mailto=name@company.com
_mail_subject="Alert for $ORACLE_SID on $HOSTNAME"
_today=$(
  date '+%Y-%m-%d 00:00:00'
  )
_yesterday=$(
  date -d yesterday +'%Y-%m-%d 00:00:00'
  )

_my_result=$(
  adrci exec="
    set home $ORACLE_SID;
    show alert -term -P \\\"MESSAGE_TEXT like '%ORA%' and ORIGINATING_TIMESTAMP between '$_yesterday' and '$_today'\\\"
   "
  )

case $_my_result in
  ( *ORA-* ) mailx -s "$_mail_subject" "$_mailto" <<< "$_my_result"
esac
[oracle@ukedxdtmtdbs01a scripts]$

This is correct. If you want to see what happens just run the script with -xv:

Code:
bash -xv <script_file>

If there are no errors for the specified period (yesterday), nothing happens,
otherwise you'll receive the mail with the errors.

Thanks very much - It worked as there were no errors yesterday, but I would have expected for it to mail me - and say that - or does it only mail on error, i.e if it finds something? output from running with -xv



Code:
[oracle@ukedxdtmtdbs01a scripts]$ bash -xv test.sh
#!/bin/bash


ORACLE_HOME=ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
+ ORACLE_HOME=ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
ORACLE_SID=DCTMTEST1
+ ORACLE_SID=DCTMTEST1
ORAENV_ASK=NO
+ ORAENV_ASK=NO
export ORACLE_HOME ORACLE_SID ORAENV_ASK
+ export ORACLE_HOME ORACLE_SID ORAENV_ASK

_mailto=name@company.com
+ _mailto=name@company.com
_mail_subject="Alert for $ORACLE_SID on $HOSTNAME"
+ _mail_subject='Alert for DCTMTEST1 on ukedxdtmtdbs01a.pearson.com'
_today=$(
  date '+%Y-%m-%d 00:00:00'
  )

  date '+%Y-%m-%d 00:00:00'
++ date '+%Y-%m-%d 00:00:00'

+ _today='2011-06-08 00:00:00'
_yesterday=$(
  date -d yesterday +'%Y-%m-%d 00:00:00'
  )

  date -d yesterday +'%Y-%m-%d 00:00:00'
++ date -d yesterday '+%Y-%m-%d 00:00:00'

+ _yesterday='2011-06-07 00:00:00'

_my_result=$(
  adrci exec="
    set home $ORACLE_SID;
    show alert -term -P \\\"MESSAGE_TEXT like '%ORA%' and ORIGINATING_TIMESTAMP between '$_yesterday' and '$_today'\\\"
   "
  )

  adrci exec="
    set home $ORACLE_SID;
    show alert -term -P \\\"MESSAGE_TEXT like '%ORA%' and ORIGINATING_TIMESTAMP between '$_yesterday' and '$_today'\\\"
   "
++ adrci 'exec=
    set home DCTMTEST1;
    show alert -term -P \"MESSAGE_TEXT like '\''%ORA%'\'' and ORIGINATING_TIMESTAMP between '\''2011-06-07 00:00:00'\'' and '\''2011-06-08 00:00:00'\''\"
   '

Modified the script as per your requirement (mail in any case).
There was an error in the previous version of the script that I corrected: oraenv wasn't sourced. You may need to adjust the path to oraenv.

Code:
#!/bin/bash


ORACLE_HOME=<your_oracle_home>
ORACLE_SID=<your_oracle_sid>
ORAENV_ASK=NO
export ORACLE_HOME ORACLE_SID ORAENV_ASK

# you may need to adjust the path to oraenv
. "$ORACLE_HOME"/bin/oraenv

_mailto=<your_email_address>
_mail_subject_ok="No ORA- for $ORACLE_SID on $HOSTNAME"
_mail_subject_ko="ORA- for $ORACLE_SID on $HOSTNAME"

_today=$(
  date '+%Y-%m-%d 00:00:00'
  )
_yesterday=$(
  date -d yesterday +'%Y-%m-%d 00:00:00'
  )  

_my_result=$(
  adrci exec="
    set home $ORACLE_SID;
    show alert -term -P \\\"MESSAGE_TEXT like '%ORA%' and ORIGINATING_TIMESTAMP between '$_yesterday' and '$_today'\\\"
   "
  )

[[ $_my_result == *ORA-* ]] && 
  _mail_subject=$_mail_subject_ko ||
    _mail_subject=$_mail_subject_ok

mailx -s "$_mail_subject" "$_mailto" <<< "$_my_result"


Please post the output of bash -xv <script_name> so I can verify the correct execution.
