Issue of CRLF chars

I faced a very weird problem while I was trying to find log, check out or update files from the CVS repository. The following error message was flashed on the screen:
[myuserid@localhost java]$ cvs log .
myuserid@mycvshost's password:
cvs-1.11.17_p2 log: Logging .
: No such file or directoryopen directory /cvsroot/my/repository
cvs-1.11.17_p2 log: skipping directory
myuserid@mycvshost's password:
" but pserver says "/cvsroot/my/repository"/my/repository

I could sense that this might be related to some CRLF (Carriage Return-Line Feed) issue, as all the error lines seem to be starting with what look like end of string delimiters (":" or "\""). So to further clarify my doubt I redirected the output to a file and this is the exact error message I was getting:

cvs-1.11.17_p2 log: Logging .
cvs-1.11.17_p2 log: cannot open directory /cvsroot/my/repository^M: No such file or directory
cvs-1.11.17_p2 log: skipping directory
Protocol error: Root says "/cvsroot/my/repository^M" but pserver says "/cvsroot/my/repository"

Gotcha! You see those "^M" chars? I figured what was the problem. I had checked out all the files in my Win XP workstation, and FTPed the entire tree to my Linux box. That caused the whole issue!

To rectify that, do a dos2unix on all the files under each of the CVS directories. A simple script to do this task is given below:
for dir in `find . -name CVS -type d` ; do
dos2unix $dir/*
done

Remember: We are not doing a dos2unix on all the source files in those directories, rather we do dos2unix only on the CVS related files. Keep this in mind.

The mysterious ORA-03111 error

Recently one of the applications that I developed started throwing exceptions, that had the following message: SQL state [72000]; error code [1013]; ORA-03111: break received on communication channel When I googled around, I couldn't come across anything useful. Sadly enough most of the sites just showed the documentation for that error, without any explanation from anyone experiencing that issues. So here you go, with the best possible explanation that I could come up with. My application sets two things on the connection that is throwing this exception: It sets the fetchSize to be 2500 rows It sets the query timeout to be 10 seconds The database server and the application are separated over a long latency network (actually there is a NetEm box that emulates the long latency between these two boxes) which has a latency characteristic of 50+/-5 milliseconds. This is the whole setup. It is important to understand how the timeout is handled by the Oracle client (in my case JDBC clien...

Note on allocationSize parameter of @SequenceGenerator while using JPA

I ran into what I thought as an issue while I was using the sequence ID generation strategy in JPA. The JPA provider I am using is Hibernate. I think sharing my experience will save someone some time. To use a sequence (For e.g. Oracle sequence) to generate values and assign them to the ID field of your persistence object, you will following something like this: @Id @Column(name = "ITEM_ID") @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="ItemIdSeqGenerator") @SequenceGenerator(name="ItemIdSeqGenerator", sequenceName="ITEM_ID_SEQ", allocationSize=1) private long itemId; This means the following things: The @Id annotation says that the field itemId is a primary key. The @Column annotation says that the corresponding column in the database is ITEM_ID. The @GeneratedValue says that the value that needs to be populated in the itemId should be generated, while that object is persisted. The strategy to generate the value is to...
