How to use a string in the for loop?
Hi Guys,

I have the below 2 exception which I want to monitor and subsequently many more. My problem is since the For loop takes the syntax for variable in word1 word2 as separate entities and my error strings are consisting of many words , how to treat the whole error string as a single entity.

Code:
 
Exception 1: org.com.Exception JMS MQ Error
Exception 2: org.db.Exception Db2 SQL Error

What can I do to modify the below code so that I can include individual exceptions in a for loop? The below code will treat each word as a different variable

Code:
for exception in org.com.Exception JMS MQ Error org.db.Exception Db2 SQL Error

Ok. I got it .. It shud be in the following format.

Code:
for exception in "org.com.Exception JMS MQ Error" "org.db.Exception Db2 SQL Error"

---------- Post updated at 03:59 AM ---------- Previous update was at 01:55 AM ----------

Now I am facing another issue where the Awk script is not recognizing the variable passed in for loop i.e. in the below script, it is probably searching for $error string instead of the value of error variable.

How to make awk script recognize the value of the error variable?

Code:
 
rm /tmp/jvm1error.txt
echo "Error" >/tmp/jvm1error.txt
for error in "org.com.Exception JMS MQ Error" "org.db.Exception Db2 SQL Error"
do
a=$(awk -vDT=$(date +"%y%m%d%H%M" -d"- 3 hour") '
                     {sub(/^\[/,"")
                      split ($1, D, "/")
                      split ($2, T, ":")
                      AT=sprintf ("%02d%02d%02d%02d%02d", D[3], D[1], D[2], T[1], T[2])}
             AT > DT && /$error/
        ' /logs/websphere/*jvm1*/SystemOut.log)
 
echo "$a" >> /tmp/jvm1error.txt
done

xml::sax::exception5.16

XML::SAX::Exception(3)					User Contributed Perl Documentation				    XML::SAX::Exception(3)

NAME

       XML::SAX::Exception - Exception classes for XML::SAX

SYNOPSIS

	 throw XML::SAX::Exception::NotSupported(
		 Message => "The foo feature is not supported",
		 );

DESCRIPTION

       This module is the base class for all SAX Exceptions, those defined in the spec as well as those that one may create for one's own SAX
       errors.

       There are three subclasses included, corresponding to those of the SAX spec:

	 XML::SAX::Exception::NotSupported
	 XML::SAX::Exception::NotRecognized
	 XML::SAX::Exception::Parse

       Use them wherever you want, and as much as possible when you encounter such errors. SAX is meant to use exceptions as much as possible to
       flag problems.

CREATING NEW EXCEPTION CLASSES

       All you need to do to create a new exception class is:

	 @XML::SAX::Exception::MyException::ISA = ('XML::SAX::Exception')

       The given package doesn't need to exist, it'll behave correctly this way. If your exception refines an existing exception class, then you
       may also inherit from that instead of from the base class.

THROWING EXCEPTIONS

       This is as simple as exemplified in the SYNOPSIS. In fact, there's nothing more to know. All you have to do is:

	 throw XML::SAX::Exception::MyException( Message => 'Something went wrong' );

       and voila, you've thrown an exception which can be caught in an eval block.
