Re: Re : Batch file for check the status of SQL / ORACLE

Hello,

What I do is the following:

1) Once my oracle tables are updated with new data, I create a flag file (txt file) in a specific location.

2) Every 30 min I run a qvw file that checks if that file has been updated. If the file has been updated, then this QVW execution is successful and I trigger my application .qvw to load on successful completion of the this file (though QMC)

Here's is the code that you should put in a .qvw file that checks if the flag file has been updated:

//Set info variables

LET vScriptStarts          =          NOW();

LET vUser          =          OSUser();

LOAD

          NUM(filetime( 'D:\FilePath\flag_file.log' )) as UpdateDate //loads when was the last time the flag file was updated

AutoGenerate(1);

SET vIntervalLoad          =          00 00:10; //Interval load used to load data Format: DD HH:MM

IF Peek('UpdateDate',0) > '$(vLastUpdate)' THEN

          LET vScriptEnds          =          NOW();

          LET vLastUpdate          =          NUM(NOW());

  //Here the script ends successfully

ELSE

//Will exit script with error (fail)

          LET vLastUpdate          =          NUM(NOW());

           LET vScriptEnds          =          NOW();

          SET ErrorMode = 2;

  LET vErrorCode = $(=o); // This causes an internal error, therefore,

ENDIF

EXIT SCRIPT;

I hope this helps.
