Thanks Fred for setting the approach for me.

has the script changed recently (i.e about two months ago)?  Has anything the script does/calls/talks to/looks at changed?  You need to figure out where to focus your investigation, and the logging is your best bet.

If you can't look at or add any, then try and figure out how far the script does get...it always frustrated me that we never had a shell debugging too...but sometimes you can even run the commands manually, one at a time, to figure out what might be hanging...but that depends on what exactly each command does...

Hi,

My client's applications are running on a very old version of Linux (RHEL 5.5). Since last 2 months, many of the script files written in Unix Shell Scripting language are getting hung. Is there any specific area / reason to look for to investigate the cause of the scripts getting hung.

Any hints/help in this regard will be of great help!!

Hi,

We are facing a very strange issue in Production environment. The application code is developed to read values from the database for the fields - length, width, etc. and send these values in a file to another system. The values stored in the Database are having '.' in them. But the values in the files are showing ',' for the decimal numbers. For eg. '5.2' in database, is shown as '5,2' in the final output file. This behaviour is observed from a certain day. Earlier, the value in the file used to be a dot (.).

In the acceptance and stage environments, the behaviour is as expected, that is, a dot is getting sent as a dot and not a comma.

We are suspecting this to be due to some network patch or other environmental issues like locale, etc.

Does anyone of you have any idea about what might be causing this issue all of a sudden? This was not the case before and there is also no code change in the application.


Thanks in Advance.

Dear All,

I am fairly new to the concept of CI/CD, Jenkins. Can anyone suggest me good books on Jenkins which would be both - fairly quick to learn as well as covering most of the stuff in it.

Hi,

I have a jboss application server running on a server having a certain dns name say abc.com. From some external machine, when I ping abc.com, it resolves to a certain IP address.
Now, when I hit a URL from a web browser from the external machine with abc.com, the url works (i.e. the application runs and return the response). However, when I use the IP address(to which abc.com resolves when a ping command is issued) instead of abc.com, the application does not respond. Why is it that when a ping is issued on abc.com, the IP address that it resolves to, when it is used it does not work, however it works only with abc.com?

Can anybody explain me how does this DNS and IP address resolution work internally at network side?

Hi All,

I have a web application which calls multiple servlets under it. The application is running fine, however, on of the servlets under the application has all of a sudden stopped running. This was noticed as there were no logs in that servlet log file. What might be the reason of it? And is there any way to identify whether any such servlet goes down in a web application?

Regards,
Pankaj
Thanks. But is it a stable version? And till when would it be in support? For next 2 years atleast?

Dear All,

We are working on upgrading the JBOSS application server because of end of support for the current version. The current version of JBOSS application server we are using is EAP 4. Can somebody tell me which version would be recommended to upgrade to whose support will be available at least for 2 more years. Also, it should be supportive on Linux RHEL 7.

Also, it would be great to know the Java version that would be supported by the recommended JBOSS application server version.

I meant to say, while performing development, I would be needing a tool which can be integrated into Eclipse and also a standalone tool which should keep monitoring the application when it is running on Production environment.

Thanks for suggestion Pete. I am looking for both - a standalone would also be fine and if it can be integrated with Eclipse as a plugin that is also fine. I am using Eclipse.

Dear All,

I would like to know if there is any open source tool in Java which can analyze the code and give an output showing areas in code that take maximum time to execute.

Thanks in advance!!

Hi,
Can anyone suggest a good online tutorial/pdf which explains usage of different classes involved in JSF like Component, UIComponent, Renderer, etc? It would be good to have a book having sufficient examples to show the usage.

O'Reilly has a good book on Jenkins, but it is old and some things have changed.

There's also the official docs which are good but a little dry.

I skimmed this tutorial and it looks good.



Thanks Jeanne.
