PuTTY X11 proxy: wrong authorisation protocol attempted Error: Can't open display: localhost:X.Y

This site helped with the solution:

http://froebe.net/blog/2008/11/14/getting-xlib-putty-x11-proxy-wrong-authentication-protocol-attempted-i-have-the-answer/

This site helped with configuring Xming:

http://www.math.umn.edu/systems_guide/putty_xwin32.html

Here's what I did (this assumes you have Xming installed and configured):

After installing Xming on a Windows box, I installed PuTTY.  I configured my PuTTY session for X11 forwarding as follows:

1. Start PuTTY

2. Enter a name or IP address in the Host Name (or IP address) box and for Connection type, select SSH

3. Save the session

4. In the Category section, expand Connection then SSH, then X11

5. On the Options controlling SSH X11 forwarding screen, check Enable X11 forwarding and MIT-Magic-Cookie-1

6. From the Category section on the left, click Session and then click Save in the Basic options for Your PuTTY session section

7. Start an Xming session, followed by an SSH session from PuTTY

8. From your newly opened SSH session, type xclock

9. An xwindow clock will appear on your Windows server

10. Now su - oracle

11. Attempt the same by typing xclock and you'll see an error such as this:

PuTTY X11 proxy: wrong authorisation protocol attempted Error: Can't open display: localhost:11.0

12. Open another PuTTY session and type the following:

# xauth list
localhost.localdomain/unix:0  MIT-MAGIC-COOKIE-1  1425043ba52e4f50f597c83d434baf82

13. In your oracle session, type the following:

$ xauth add localhost:0  MIT-MAGIC-COOKIE-1  1425043ba52e4f50f597c83d434baf82

14. Export your display to your Windows box:

$ export DISPLAY=192.168.10.120
$ export DISPLAY=localhost:10.0
Thanks for the correction to Anonymous posted January 25, 2013.

15. Run xclock, and you should see the clock on your Windows box

Running yum install <package_name> gives "The requested URL returned error: 404"

On a recently created CentOS 6.2 x64 VM, I tried to install some packages such as compat-libstdc++-33.x86_64 but when I ran the command:

# yum install compat-libstdc++-33.x86_64

I got the following errors:

Automated Process to Apply Oracle PSU for Multiple Instances (Oracle 10g)

Assumes that there is more than one instance of an Oracle database in a Streams environment.

Assumes that a patch is to be applied along with a PSU.

Assumes that the listeners have been stopped.

Assumes that all relevant patches have been copied to $ORACLE_HOME/patches.

Should also work for 11g environments.

The operator is asked to run the script in the following order:


Apply the Patch (e.g. Patch ID 11724977)
1. Shutdown all database instances 
   $ sh patch_it.sh shutdown

2. Apply the patch 
   $ sh patch_it.sh patch_apply

3. Start up the database instances 
   $ sh patch_it.sh startup 

Apply the PSU 

1. Stop streams (note that for this case, the PSU does not require that the instances be shutdown). 

   $ sh patch_it.sh stop_streams 

2. Apply PSU
   $ sh patch_it.sh psu_apply 

3. Start streams 

   $ sh patch_it.sh start_streams 

Post-Installation Procedure
1. Check that the patch has been installed (this verifies that patch 11724977 has been applied) 
   $ sh patch_it.sh patch_check 

Back-out Procedure
1. Shutdown all database instances 
   $ sh patch_it.sh shutdown



2. Rollback the patch (Patch ID 11724977) 
   $ sh patch_it.sh patch_rollback

3. Start up all instances 
   $ sh patch_it.sh startup

4. Stop streams 
   $ sh patch_it.sh stop_streams

5. Rollback the PSU 
   $ sh patch_it.sh psu_rollback

My first PostgreSQL stored function...

Goal
------
Have the following table:
ld_operatingsystem

        Column        |            Type             | Modifiers
----------------------+-----------------------------+-----------
 computer_idn         | numeric                     |
 operating_system_idn | numeric                     |
 ostype               | character varying(255)      |
 version              | character varying(255)      |
 laststartuptime      | timestamp without time zone |
 facility_id          | numeric                     |
 suitename            | character varying(255)      |

I need to update the suitename column so that it is composed of the concatenation of the ostype and version columns.

Start a psql session and paste the function:

create or replace function u_ld_tbl() returns void as $$

declare

   userRecord record;

begin

   for userRecord IN
      select computer_idn, operating_system_idn, ostype, version from ld_operatingsystem
   loop
      update ld_operatingsystem
      set suitename = userRecord.ostype||' '||userRecord.version
      where computer_idn = userRecord.computer_idn
      and operating_system_idn = userRecord.operating_system_idn;

      raise notice 'Updated %, % ', userRecord.computer_idn, userRecord.operating_system_idn;
   end loop;

   return;
end;

$$ language plpgsql;

The function can be invoked from psql as follows:
