The bit bucket

The bit bucket

Computer jargon as the "/dev/null"  means a place for disposing unwanted output messages from a process. A good program must always have an output in order for us to debug the errors. But if the process becomes weird  it start to freeze resources allocated cannot be released for other computing needs. The memory allocation will always be reserved for that process.nd this type of programs may cause  "Kernel Panic" or "BSOD"

Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.

/bin/bash: Permission denied

[root@host /]# su - user1

/bin/bash: Permission denied

Scenario:  My system is not responsive to any process, so i was forced to reboot. Suddenly i cannot login as ordinary user  "user1" 

Solution:  I look the permission of /bin/bash

[root@host ~]$ ls -l /bin/bash

-rwx------. 1 root root 938736 May 10  2012 /bin/bash

tried to change the permission 

[root@host ~]$ chmod 700 /bin/bash

-rwxr-xr-x. 1 root root 938736 May 10  2012 /bin/bash

Then I try to change the permission of the whole /bin  directory

[root@host ~]$ chmod -R 755 /bin

NOW I  CAN login...

Database Mysql/MSaccess to Oracle migration all weekend

Its been almost a week trying to solve this database migration. The source in msaccess, mysql, csv and text file and my target database is oracle. 

Here are the following steps in my migration path:

1. Install oracle database server Oracle Database 11gR2 on CentOS 6.3 64 bit

2.  Install Sqldeveloper on MacOSX 10.6.8 64bit plus third party database connection (jtds driver, mysql driver and access driver)

3.  Oracle database repository preparation 

4.  Actual migration process using sqldeveloper migration tool.

5. Test and verify migration process.

Details of this process is not part of this post.

    Beautiful is better than ugly.

    Explicit is better than implicit.

    Simple is better than complex.

    Complex is better than complicated.

    Flat is better than nested.

    Sparse is better than dense.

    Readability counts.

    Special cases aren't special enough to break the rules.

    Although practicality beats purity.

    Errors should never pass silently.

    Unless explicitly silenced.

    In the face of ambiguity, refuse the temptation to guess.

    There should be one-- and preferably only one --obvious way to do it.

    Although that way may not be obvious at first unless you're Dutch.

    Now is better than never.

    Although never is often better than *right* now.

    If the implementation is hard to explain, it's a bad idea.

    If the implementation is easy to explain, it may be a good idea.

    Namespaces are one honking great idea -- let's do more of those!
