put a stop to that.
Just put the desired value in place of the 0 in the “port_binding” section.

ascii dumps and converts to multilangual hexes.
US7ASCII is outdated, it slowely drives me insane.
Those are a few of my least favorite things…

Here we are, struggling again. *sigh…

The skinny:
Read through Oracle’s NLS_LANG faq. Again. Don’t argue, just do it. Yes, Again!
Check your codepage, I’ll assume your on Windows otherwise you wouldn’t be in this mess.
For arguments sake, let’s assume it’s 850.

Microsoft Windows [Version 6.0.6002]
Copyright (c) 2006 Microsoft Corporation.  All rights reserved.

c:\Windows>chcp
Active code page: 850

Set your NLS_LANG to: american_america.we8pc850

Start SQLPlus.

Note to the weary:
When working remotely via Citrix, it’s at all good possible you’ll check your codepage, determine it’s that 850, set your NLS_LANG to american_america.we8pc850, run your script that’s located on a mounted share and still have garbage.
That.. that I can’t help you with.. Still need to figure that one out. I suppose it’s due to the fact that the scripts are compiled on another system, placed on the share and both environments may have different codepages than 850. Maybe another time, eh!?

Update ::
According to RedGrittyBrick on superuser.com, it seems that Notepad uses ANSI as another word for WE8MSWIN1252. Set your NLS_LANG to AMERICAN_AMERICA.WE8MSWIN1252 and be golden again…

Somehow, from somewhere, my virtual console stopped connecting. The java console showed the following messages:
Missing Application-Name manifest attribute for: https://***.***.***.***:443/software/avctKVM.jar
jan 18, 2017 3:41:48 PM java.util.prefs.WindowsPreferences

====setPowerMenuStatus: (##2)
01/18/2017 03:41:51:018: Connection failed.

Pretty cryptic, huh!? And good luck trying to find a solution through google…
Of course, mine was the case: “..but it worked last week!”
Than I remembered, that I had installed HitmanPro.Alert. Could it be… No! surely not.

Well, of course it was and don’t call me Shirley!

Using the advanced interface, under “Risk reduction”, click the icon that looks like fusion between the CMD and network share icon. This is the “Network lockdown – command-and-control” option. When this is active, connection to/via the virtual console is prohibited.

Running Windows Server 2012 R2 HYPER-V Core but what to do regarding backups..!?

Easy.

Install the Windows Server Backup feature. As I am using HYPER-V Core, I can install the feature using server manager on my laptop.
Than, create a shared folder on my HYPER-V server with:

net share BCK=C:\BCK /GRANT:Everyone,FULL

And finally, backup the virtual machine using wbadmin.exe, like so:

WBADMIN START BACKUP -backupTarget:\\<servername>\BCK -hyperv:<vm_name>

Because I’ve got Swiss cheese for memory, I created a little script to do this for me:

@ECHO OFF

EXEC DBMS_STATS.GATHER_TABLE_STATS(‘<user>’, ‘<table_name>’, estimate_percent => NULL, cascade => TRUE);

Instead of estimating the statistics using a given percentage, this will hit all rows.

find . -type f -mtime -1 -exec mv ‘{}’ /ora/bin \;

This will move all files found that were created that day to the directory /ora/bin.

useradd -u 200 -d /export/home/oracle -g oinstall -G dbadmin -m -s /bin/bash -c “RDBMS install user” oracle

Now, what does it mean?
-u = userid (it is convenient to keep this the same on multiple systems)
-d = home directory
-m = make the home directory if it doesn’t exist (believe me, it’s quite frustrating if you don’t (know) use this one.)
-s = which shell to use
-c = comment about the user

and at the end the user’s username.

I was just playing on the windows cli, trying to create a shortcut to a mysql binary directory, where I noticed that a shortcut/link to a directory didn’t behave as I initially expected it to do. Enter Jon Coombs on superuser.com:

:\Users\user5\Desktop>mklink /D mysymlink  "C:\ProgramData\Microsoft\Windows\S
tart Menu\Programs\G"
symbolic link created for mysymlink <<===>> C:\ProgramData\Microsoft\Windows\Sta
rt Menu\Programs\G

C:\Users\user5\Desktop>cd mysymlink

C:\Users\user5\Desktop\mysymlink>

Because I created my symlink outside of my user directory, I had to create it using administrator privileges and added privileges to my user via advanced security settings.

To remove the carriage-return character from a windows originating file in vi:

:%s/<Ctrl-V><Ctrl-M>/g

or
:%s/\r//g

In UNIX, you can escape a control character by preceeding it with a CONTROL-V. The :%s is a basic search and replace command in vi. It tells vi to replace the regular expression between the first and second slashes (^M) with the text between the second and third slashes (nothing in this case). The g at the end directs vi to search and replace globally (all occurrences).

After several mysterious data disappearances in MySQL, I finally had enough and went on to configure RoR to use a remote Oracle db installation.
Here’s what’s what:

Versions:
Rails 4.0.5
ruby 2.0.0p481 (2014-05-08 revision 45883) [x86_64-linux]

Gemfile:
gem 'ruby-oci8', '~> 2.1.5'
gem "activerecord-oracle_enhanced-adapter", "~> 1.5.0"

database.yml
development:
  adapter: oracle_enhanced
  encoding: utf8
  database: 
  username: 
  password: 

.bashrc
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export TNS_ADMIN=/usr/lib/oracle/12.1/client64/tns
export ORACLE_HOME=/usr/lib/oracle/12.1/client64
export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib
export PATH="$PATH:$HOME/.rvm/bin:$LD_LIBRARY_PATH:$ORACLE_HOME/bin:$TNS_ADMIN" # Add RVM to PATH for scripting
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

After several tries to catch the culprit, I was not able to figure out what was going on, it even got to the point where I created a fresh user after a

rake db:refresh

and after a quick bite to eat my user was gone!.

Troubleshooting:
First things first: Can you connect to the db via sqlplus!?
Can Ruby connect to the database?:

ruby -rubygems -e "require 'oci8'; OCI8.new('','','').exec('select * from dual') do |r| puts r.join(','); end"

When you have set the NLS_LANG parameter, you should just get ‘X’ as output.

Having a server grade motherboard has its downsides as well, more specifically, getting the thing to boot from an installation disk when it just won’t use your DVD drive at all…

Luckily, good things come to those who search relentlessly!

In this case, it comes in the form of a FAQ entry. Just in case it may move and I need it again, here’s what what:

Please keep dvd-drive connect to SATA 5 or 6.

Change following BIOS setting:
Advanced --> PCIe/PCI/PnP configuration --> Launch Storage OpROM policy --> Legacy only
Advanced --> Chipset configuration --> Integrated IO configuration --> Detect Non-compliance device --> enable
Advanced --> Boot feature --> INT19 Trap response --> Postponed

Working through the excellent rails tutorial by Michael Hartl, somewhere around the end chapter 9 I came across some unusual behavior of (what I suspect) Ruby/Rails. My data, which is committed to a MySQL database, kept disappearing.
Whenever a change was made to any of the spec or controller files, all my users would be gone 🙁
To get a grip on who the culprit is, I went off to create some triggers who would log what happened and when:

CREATE TABLE logger
( logger_id         INT UNSIGNED AUTO_INCREMENT PRIMARY KEY
, logger_event      VARCHAR(50)
, logger_table      VARCHAR(50)
, logger_instring   VARCHAR(100)
, logger_outstring  VARCHAR(100)
, creation_date     DATETIME
, last_update_date  DATETIME) ENGINE=MyISAM;

DELIMITER $
CREATE TRIGGER trg_users_insert
AFTER INSERT ON users
FOR EACH ROW begin
INSERT INTO logger VALUES ( null
           ,'insert'
           ,'users'
           , new.email
           , null
           , new.created_at
           , null );
END$

CREATE TRIGGER trg_users_update
AFTER update ON users
FOR EACH ROW begin
INSERT INTO logger VALUES ( null
           ,'update'
           ,'users'
           , old.email
           , new.email
           , old.updated_at
           , new.updated_at );	
END$

CREATE TRIGGER trg_users_delete
before delete ON users
FOR EACH ROW begin
INSERT INTO logger VALUES ( null
           ,'delete'
           ,'users'
           , old.email
           , null
           , null
           , current_timestamp );	
END$

Not the most sophisticated piece of code ever, but let’s see if it does the trick…

When working with Windows Server products any security setting can be altered by using the local security policy.
Enter HYPER-V server core.

Because I’m just meddling around with it, I definitely want to be able to use it on a as much as TeleTubby level as possible. Queue Josip Medved. Following his post:
Run this on a server where the configuration already meets your requirements or where you can edit the file created in the code below:
secedit /export /cfg X:\new.cfg

The task has completed successfully.
See log %windir%\security\logs\scesrv.log for detail info.

When needed, edit the part below:
[System Access]
MinimumPasswordAge = 0
MaximumPasswordAge = 39
MinimumPasswordLength = 0
PasswordComplexity = 1
PasswordHistorySize = 0
...
In this case you’d want to set the PasswordComplexity to 0.
Move the file to your HyperV server and run the following code:
secedit /configure /db C:\Windows\security\new.sdb /cfg X:\new.cfg /areas SECURITYPOLICY

The task has completed successfully.
See log %windir%\security\logs\scesrv.log for detail info.

Worked for me!

## Update::
OR!..
You can just
cmd::> gpedit.msc /gpcomputer: remote-computer
powershell::> Invoke-Command -ComputerName FQDN-of-computer {gpupdate /force}
Also works very nice and isn’t that cumbersome.

Ran too many times into issues with GUI Disk Management when trying to repartition a non-Windows partitioned thumb-drive:
1.Connect your disk.
2.Run cmd as an Administrator.
3.Run diskpart.exe. Use ? if you need help in this program.
4.list disk
5.Find the disk that corresponds to your USB disk. select disk n where n is the number of the disk. Confirm that you’re using the right disk with detail disk.
6.clean (Warning: This command erases the disk’s partition information)
7.create partition primary. No size is needed if you want to use the whole disk
8.active. Optional. Marks the partition as potentially bootable.
9.format fs=fat32 quick. You can choose NTFS or exFAT instead of FAT32 if you want.
10.assign. Assigns the disk a drive letter.
11.exit to quit.

When sending mail with attachement from the command line, I usually use:
uuencode | mailx -r sender_user@example.org -s “Subject header” receiver_user@example.org

On HP-ux, this does not work. As stated on the webs, this rips the guts out of the file and puts it in the body of the message. This has something to do with the MIME headers being added which triggers the SMTP relay agent to do it’s grizzly work.
So add the “-m” flag and all is well, this is confirmed to work on HP-UX B.11.31:

uuencode | mailx -m -r sender_user@example.org -s “Subject header” receiver_user@example.org

In this particular case, I was trying to export from a 10.2.0.4 db with exp from 8.1.7.4.

Just came across a directory with these permissions: drwxr-sr-x

Here’s howto set it:

chmod 2755 

Here are the sources: example man

useradd -u 200 -d /export/home/oracle -g oinstall -G dbadmin -m -s /bin/bash -c “RDBMS install user” oracle

Now, what does it mean?
-u = userid (it is convenient to keep this the same on multiple systems)
-d = home directory
-m = make the home directory if it doesn’t exist (believe me, it’s quite frustrating if you don’t (know) use this one.)
-s = which shell to use
-c = comment about the user

and at the end the user’s username.

UPDATE::
I noticed that the order in which the flags are given are important on version 11.2:

We regularly get the request for a refresh of an OTA database.
Usually, the end-users would like for their settings to survive the refresh.

We use a couple of scripts to save these setting (eg. passwords and such), however, the database links didn’t survive last time.
Probably because the passwords aren’t visible anymore in 10g.
Update!: Not true, just had a peek in SYS.LINK$ ver 10.1.05 and column AUTHPWD still had (unencrypted!) values.
Update2!: Somewhat true, just had a peek in SYS.LINK$ ver 10.2.0.1 & 10.2.0.2 and column PASSWORDX has encrypted values.

It is possible to retrieve the passwords using dbms_metadata.get_ddl.

USE_SHARED_SOCKET
You can set parameter USE_SHARED_SOCKET to true to enable use of shared sockets. If this parameter is set to true, the network listener passes the socket descriptor for client connections to the database thread. As a result, the client does not need to establish a new connection to the database thread and database connection time improves. Also, all database connections share the port number used by the network listener, which can be useful if you are setting up third-party proxy servers.
This parameter only works in dedicated server mode in a TCP/IP environment.
If this parameter is set, you cannot use the 9.0 listener to spawn Oracle7 release 7.x databases.
To spawn a dedicated server for an Oracle database not associated with the same Oracle home as the listener and have shared socket enabled, you must also set parameter USE_SHARED_SOCKET for both Oracle homes.

USE_SHARED_SOCKET could be a performance bottleneck if you have more connections to the database. The load on using the same socket on Windows has been very weak with respect to performance.
So the answer would depend on how many simultaneous connections will hit the listener at a point of time.
I don’t have any benchmark values for this ( there was never a need for this ).
But we decided against the use of this with just 50 connections.

And how to roll ’em back:

Stop Spine/MQ and query dba_2pc_pending and/or dba_pending_transactions.

As sysdba :

rollback force 'local_tran_id#';
exec dbms_transaction.purge_lost_db_entry('local_tran_id#');
commit;

Appearantly Nero Scout mucks about in the browser history, causing the “delete all” to hang.
I’m using IE7 in combination with Nero8, here’s how to solve it:

* Start

* Nero Toolkit
* Nero Scout -> clear the “enable” check box

Problem solved !

In order to log on to DB console running on a Windows platform, the user with which you (want to) log onto the host must be granted the privilege to log on as a batch job.

* Go to control panel/administrative tools.
* click on “local security policy”.
* click on “local policies”.
* click on “user rights assignments”.
* double click on “log on as a batch job”.
* click on “add” and add the user that was entered in the “normal username” or “privileged username” section of the EM Console.

How on Earth do you return the column definitions of a table as the names for the start- and endtags ?

On Adobe.com® there is a tutorial for Adobe Flex® where the result of a query to a MySQL® database is returned via PHP as XML. The column names retrieved in this query are looped through and put in the start- and endtags in the XML-document.
