Rosdi's questions

mirrorlist.centos.org no longer online?

I can resolve to centos.org but not to mirrorlist.centos.org

Here is the output of my resolv.conf, dig, and nslookup if anyone interested.

rosdi@H-TQ0nmTkQIbRhN:~/test_ssl$ nslookup mirrorlist.centos.org

Address:        1.1.1.1#53

** server can't find mirrorlist.centos.org: NXDOMAIN

rosdi@H-TQ0nmTkQIbRhN:~/test_ssl$ nslookup centos.org

mxtoolbox also showing the same thing.

I just installed the latest java in /usr/jdk/jdk1.6.0_30

Now how do I make this java is the default java for the entire OS? As of now it is still using java 1.5

Thanks.

I am using Solaris. I have several directories with the following names:

saa_first.data
saa_second.data
saa_third.data

I want to remove these directories along with its content, so I use:

rm -fr saa*

What I get is the following questions:

rm: examine files in directory saa_first.data (yes/no)? n
rm: examine files in directory saa_second.data (yes/no)? n
rm: examine files in directory saa_third.data (yes/no)? n

I don't get any error, but the directories are not deleted. What gives?

Here is my Solaris info:

$ cat /etc/release
                  Solaris 10 10/08 s10s_u6wos_07b SPARC
       Copyright 2008 Sun Microsystems, Inc.  All Rights Reserved.

UPDATE:

It works after I use the following command:

/usr/xpg4/bin/rm -fr saa*

I am still interested with the explanation why it didn't work with /usr/bin/rm though.

I am developing a web apps, this web application will be using MySQL.

Now I need to replicate my client's Oracle database into MySQL, only a few tables will be involved.. a table can be up to 2-3 million rows.

I only have SELECT privilege on this Oracle, so don't ask me to install any kind of service on the Oracle machine. I have complete control on the MySQL side however.

The replication is only one way (Oracle to MySQL). I can write a simple script to truncate MySQL table and repopulate it every night but I think this is very inefficient, there must be a better way.

Is there any free tools I can use? Expensive database replication system is definitely out of the question.
