Hi,
Am new to Materialized View and am currently stuck with an issue on MV Refresh.
An outline of the problem is as :- Am having a Master site with 20 tables and am creating a Materialized View of that Master site. This is refreshed normally using Fast Refresh option.
Now the problem is am using a shell script to activate the refresh and a mail will be send to the MV Admin once the refresh is completed with the details like "MV_Table_Name refreshed on DD/MM/YYYY".
But in case the refresh fails due to some reason, i need the mail to be send with details as "MV_Table_Name hasn't been refreshed on DD/MM/YYYY. ORA Error Code='' & ORA Err-msg='' "

It will be very much appreciated if someone could guide me how to get the ORA ERR_NO,ORA_ERR_MSG incase an error occurs while refreshing a particular MV

Thanks in Advance,
Sanjay

HI

I have implemented same thing, although on windows.

I am using 3 files for this purpose:

1. .Batch file: for running the refresh job.
2. .sql file: containing the statements for refresh.
3. .vbs file: for sending the result of refresh job.

The test of these 3 files is as below:

File 1.

Quote:

sqlplus -s -l <uid>/<pwd>@<service> @D:\Script\Report_MV_refresh.sql
find /V "Elapsed: 00:00:00.00" D:\script\Refresh.log >D:\Script\temp.log
del D:\script\Refresh.log
ren D:\script\temp.log Refresh.log
Mailscript.vbs



File 2.

Quote:

set timing on
set pagesize 0
spool d:\script\Refresh.log
select 'Connected to <INSTANCENAME> at ' || to_char(sysdate,'dd-mon-yyyy hh24:mi:ss') from dual;
select '------------------------------------------------------------------------' from dual;
select 'Refreshing MVIEW: <Mview_Name>...' from dual;
exec dbms_mview.refresh('<Mview_name>', '?', '', true,false, 0,0,0, true);
select 'Refreshing MVIEW: <Mview_Name1>...' from dual;
exec dbms_mview.refresh('<Mview_name1>', '?', '', true,false, 0,0,0, true);
select '------------------------------------------------------------------------' from dual;
select 'Completing Report MV REfresh on <Instance_name> at ' || to_char(sysdate,'dd-mon-yyyy hh24:mi:ss') from dual;
spool off;
exit



File 3.

Quote:

objEmail.Subject = "Daily Report MV Refresh Log"

emailBody = "" + vbcrlf 'TODO: server ip

log_file = "d:\sCRIPT\refresh.log" 'TODO: Daily Refresh Log location


Dim file
set file = iFSO.GetFile(log_file)
Dim TextStream
Set TextStream = file.OpenAsTextStream(1, -2)

Do While Not TextStream.AtEndOfStream
Dim Line
Line = TextStream.readline

' Do something with "Line"
if (line=" ") or (line="") then

end if


Loop

objEmail.TextBody = emailBody

objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "<SMTP_Server_IP>" 'TODO: mail server name
objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25

I Hope this helps your cause.

You must be using UNIX, & so you can alter these .vbs & .bat files to suit your requirement.

Thanks Girish, it solved half of my problem, the issue that still needs a solution is, if for some reason, the Refresh fails for a particular MV, i need the Error Code, Err msg to be sent along with the mail.
Any idea, how it could be done. Is there any system table which saves these err code,messages and if yes, how to set it through unix

The refresh log contains all this information.
I am pasting here a sample mail that I get from this process:

Hi,
Is there any way through which we could get the Action required for a particular Error Code. i.e; any system table which saves the error code,error message, required action to solve that error .
