What is Hostname actually set to?

I have some trouble understanding what the hostname is. I have it set to 'localhost' in '/etc/hostname', and this is my '/etc/hosts'.
127.0.0.1 localhost.localdomain localhost
::1 localhost.localdomain localhost
Yet when I do 'hostname' or 'echo $HOSTNAME' in the terminal it outputs some domain related to my internet provider: "ID_HERE.access.telenet.be".
What's up with the hostname? What is it actually set to and what is it used for? Why are there configuration files if they don't seem to do anything?

Thanks for the help. Still not sure why those steps were needed?

My "/etc/hostname" contains 'localhost' and nothing else.
Did you read the link? Of course it doesn't contain anything; who is going to add it, the Easter Bunny?
I did read the link, I was confused by there being a localhost and a myhostname.

I am using a table in Numbers to plot daily graph lines. Mood swings of how I am on the day, i"m a depressive.
If I fill a cell with a step box at say zero it plots the graph. I can't actually set the cell value until the actual day but the graph plots it at zero when I don't want it to plot anything. Is there a work around. so thatbgraph only plots on the day?

The answer is (sort of) in your subject, but edited out of the problem statement in the body of your message.
When you use a stepper or a slider, the value in the cell is always numeric, and is always placed on the chart if that cell is included in the range graphed by the chart.
But if you use a pop-up menu cell, you can specify numeric or text values in the list of choices for in the menu. Numeric values will be shown on the chart. Text values will not.
For the example, the values list for the pop-up menu was:
5
3
1
Choose
-1
-3
-5
The first pop-up was set to display Choose, then the cell was filled down the rest of the column. Any text value (including a single space, if you want the cell to appear blank) may be used instead of Choose.
For charts with negative Y values, the X axis will not automatically appear at Y=0. If your value set will include negative values, I would suggest setting the Y axis maximum and minimum to the maximum and minimum values on your menu list, rather than letting Numbers decide what range to include on the chart. Place a line shape across the chart at the zero level, and choose to NOT show the X axis.

What's the recommended setting for "Process memory usage" ("process virtual" in UI) for a 64-bit host on a 64-bit OS?

Hi gurus
In resource based throttling, what's the recommended setting for "Process memory usage" ("process virtual" in the resource based throttling tab of the UI) for a 64-bit host
on a 64-bit Windows OS?
According to MS (http://msdn.microsoft.com/en-us/library/ee308808(v=bts.10).aspx):
"By default, the
Process memory usage throttling threshold is set to 25. If this value is exceeded and the BizTalk process memory usage is more than 300 MB, a throttling condition may occur. On a 32-bit
server, you can increase the Process memory usage value to 50. On a 64-bit server, you can increase this value to 100. This allows for more memory consumption by the BizTalk process before throttling
occurs."
Does this mean that 100 is the recommended setting for a 64-bit host on a 64-bit Windows?
Thanks

Hi Michael,
Recommended setting is the default setting which is 25 .dot.
If your situation is abnormal and you see message delivery throttling state to “4” when the following performance counters are high or if you expect any of you integration
process could have impact on following counters, then you can consider the suggestion by Microsoft. Don’t change the default setting.
High process memory
Process memory usage (MB)
Process memory usage threshold (MB)
You can see these counters under “BizTalk:MessageAgent”
You can gauge these performance counter and its maximum values if have done any regression/performance testing in your test servers. If you have seen these counters having
high values and causing throttling, then you can update the Process memory usage.
Or unexpectedly you’re process high throughput messages in production which is causing these counters to go high and cause throttling, then up can update the Process memory
usage.
The above two cases where I know my expected process usage (by doing performance testing) or suddenly my production server processing has gone high due to unexpected business
hike (or any reasons) which caused throttling, then do changes to default throttling setting.
Just changing the default setting without actual reason could have adverse effect where you end up allocating
more processing capacities but the actual message processing message usage ever is low means you end up investing in underutilised resources.

What is the actual use of the background print parameters

Hello all,
When we are scheduling a job it asks for print parameters like output device:
Can any one please let me know what is the actual meaning of print parameters and what it does when we set spool parameters.
Thanks, kumar.

Hi Bharani,
Normally when you execute a job in the back ground say like time taking reports or daily Scheduled background jobs, system will create a spool request for that so that you would be able to view the output of the report later and further take the printout etc. Hence, it is asking for print parameters.
Print parameters are those where you specify the output device, print preview, spool retention period etc, Basically those are the settings required for the way a print job needs to be triggered.

Is there a risk of setting a console connection timeout and what is the recommended setting?

Is there a risk of setting a console connection timeout and what is the recommended setting? Please suggest if there is any best prctice documentation that can be referred.

Hi Henrik
depend on what you need or what your security policy says for my lab gear i use 60 minutes. because i know how can access this. if you have gear outside in insecure space set it to a minimum or disable the console. everybody how can access your gear can break in. simple restart and boot w/o config. and you are in.
it realy depends how secure is your space and how much security you need.
and than the settings for policy have to match, what sec do you have if your console login and logout is secure. but when you restart you can simple break in by starting w/o config and than load it.

What is open data set and close data set

what is open data set and close data set,
how to use the files in sap directories ?

hi,
Open Dataset is used to read or write on to application server ... other than that i am not sure that there exists any way to do the same ... here is a short description for that
FILE HANDLING IN SAP
Introduction
Files on application server are sequential files.
Files on presentation server / workstation are local files.
A sequential file is also called a dataset.
Handling of Sequential file
Three steps are involved in sequential file handling
OPEN
PROCESS
CLOSE
Here processing of file can be READING a file or WRITING on to a file.
OPEN FILE
Before data can be processed, a file needs to be opened.
After processing file is closed.
Syntax:
OPEN DATASET <file name> FOR {OUTPUT/INPUT/APPENDING}
IN {TEXT/BINARY} MODE
This statement returns SY_SUBRC as 0 for successful opening of file or 8, if unsuccessful.
OUTPUT: Opens the file for writing. If the dataset already exists, this will place the cursor at the start of the dataset, the old contents get deleted at the end of the program or when the CLOSE DATASET is encountered.
INPUT: Opens a file for READ and places the cursor at the beginning of the file.
FOR APPENDING: Opens the file for writing and places the cursor at the end of file. If the file does not exist, it is generated.
BINARY MODE: The READ or TRANSFER will be character wise. Each time n characters are READ or transferred. The next READ or TRANSFER will start from the next character position and not on the next line.
IN TEXT MODE: The READ or TRANSFER will start at the beginning of a new line each time. If for READ, the destination is shorter than the source, it gets truncated. If destination is longer, then it is padded with spaces.
Defaults: If nothing is mentioned, then defaults are FOR INPUT and in BINARY MODE.
PROCESS FILE:
Processing a file involves READing the file or Writing on to file TRANSFER.
TRANSFER Statement
Syntax:
TRANSFER <field> TO <file name>.
<Field> can also be a field string / work area / DDIC structure.
Each transfer statement writes a statement to the dataset. In binary mode, it writes the length of the field to the dataset. In text mode, it writes one line to the dataset.
If the file is not already open, TRANSFER tries to OPEN file FOR OUTPUT (IN BINARY MODE) or using the last OPEN DATASET statement for this file.
IF FILE HANDLING, TRANSFER IS THE ONLY STATEMENT WHICH DOES NOT RETURN SY-SUBRC
READ Statement
Syntax:
READ DATASET <file name> INTO <field>.
<Field> can also be a field string / work area / DDIC structure.
Each READ will get one record from the dataset. In binary mode it reads the length of the field and in text mode it reads each line.
CLOSE FILE:
The program will close all sequential files, which are open at the end of the program. However, it is a good programming practice to explicitly close all the datasets that were opened.
Syntax:
CLOSE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the CLOSE is successful or not.
DELETE FILE:
A dataset can be deleted.
Syntax:
DELETE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the DELETE is successful or not.
Pseudo logic for processing the sequential files:
For reading:
Open dataset for input in a particular mode.
Start DO loop.
Read dataset into a field.
If READ is not successful.
Exit the loop.
Endif.
Do relevant processing for that record.
End the do loop.
Close the dataset.
For writing:
Open dataset for output / Appending in a particular mode.
Populate the field that is to be transferred.
TRANSFER the filed to a dataset.
Close the dataset.

How can I see what I'm actually video recording on iPad Air so that I don't include extra stuff at the borders of the image? It seems to automatically "zoom in" on the screen, but when I export the video, the picture isn't framed well.

When I try to record a video on the Ipad Air, the screen automatically "zooms in" closer than when I'm taking a photo. So I frame the interview and record it. But when I export it to post it or edit it, I discover that only the screen was zoomed in, the camera wasn't, so I have all this extra stuff around the edges of my frame.
I don't need to zoom in, but I do need to be able to see what I'm shooting--otherwise, as I'm videotaping, I'm guessing at my picture's framing. But every time I switch from photo to video mode, the screen "zooms in." How can I see what I'm actually recording?
I've been searching for an answer for this for a while, but I can't find any responses to it! Thanks.

What is the actual size of an (empty) varray in a record?

what is the actual size occupied by an (empty) varray in a record?
For example, if I create my table defined as:
create or replace type XXX as object (
myRefs VARRAY(10) of REF(yyy)
create table YYY as XXX;
what is the actual size of the record of type XXX when 'myRefs' is empty? For some reason, select data_length from all_tab_cols where table_name = YYY seems always to return 3K as the length of column myrefs.... is that correct? If not, what is the correct size?

A tad late here...
Storage sizes of REF attributes are described here:
[Design Considerations for REFs - Storage Size of REFs|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11822/adobjdes.htm#i452226]
The size of your REF attribute (or element, in your case) will depend on whether it is primary key-based or system-generated, whether it is scoped or not, and whether it carries with it a rowid hint. The overall size of your VARRAY attribute as it grows will also depend on whether you allow null REF values or not, but essentially will be the size of your REF multiplied times the number of elements in your VARRAY (plus a small, constant amount of storage for internal housekeeping, both for the attribute and for each element).
You could try the VSIZE function as an appromixation...

What Is The Best Setting To Use To Import Music?Please Help.

Hi, All
I have got an 80GB Apple Video iPod And I am still trying to figure out how to work it as I am new to using iPods.
What is the best setting to use to import CD Music and Music from the Internet to iTunes?? as I would like to listen to the highest quality there is on iTunes and my 80GB Apple Video iPod.
The settings are: ACC Encoder, AIFF Encoder, Apple Lossless Encoder, MP3 Encoder, WAV Encoder. If you have not got them to hand.
Many Thanks For Reading This And Replying To It, Much Appreciated!!
I Hope You All Have a VERY Merry New Year!!
Kind Regards, Rocky Robin

There really is no BEST setting. The "best" setting is the one that sounds the best to you.
Having said that, you also asked what setting provides the highest quality audio. In that case, you need to use a lossless format, such as AIFF, WAV, or Apple Lossless. MP3 and AAC are both compressed formats, and will not provide as good of an audio quality as a lossless format.
My personal preference would be Apple Lossless, but any of the lossless formats will produce an almost identical quality to the CD track.
Keep in mind, the files will be quite large.

What is default terminal setting for "safe sleep" for iMac C2D

I happened to use a widget for "deep sleep" which frankly I decided I did not need. Of course, after trashing same per the widget directions - the widget had changed a "setting" effecting sleep on the computer. Silly me.
There was an article in MacWorld last fall about "3" being the safe sleep mode to set a laptop (recent) from the terminal command line...but no reference to the iMac .
http://www.macworld.com/weblogs/macosxhints/2006/10/sleepmode/index.php
Not a major crisis, just want to set the "sleep code" number back to how the unit shipped from Apple!
Michael
iMac Intel C2D 2.16 GHz Mac OS X (10.4.10) 1 GB RAM, Printer HPC3180, Sounds SticksII-Z Harman Kardon

When I had the widget installed, I set it for "deep sleep" if I recall properly. After deciding to trash the widget and its preference file, I noticed that when I put the computer to sleep via the "apple" menu - the light on the monitor quickly went out entirely.
Although I could still "rouse" the computer the by tapping the keyboard etc., the wake up process was extremely slow - in fact, the computer opened up to a gray version of the desktop ...followed by a progress bar...which when completed...opened the desktop to its full Apple glory.
Perhaps, the widget set the computer to the hibernate mode - etc. I actually set the computer back to "0" via the terminal command...but since I didn't know the original default setting, I thought I'd ask...and sadly, I could not find the answer anywhere...hence the query to Apple users.
Thanks for the info, though.

On my mini ipad, I cleared the cookies/histories in the safari setting. But what does the advance-setting of the clearing the website data does? What's that used for? Thank you!

On my mini ipad, when I'm on the internet -- a few times I will see a blue small pop-up boxes telling me to allow down/load or add something like the bubble-splash game or something similar. I jusr click ignore and it goes away.. I'm not sure why it's showing up lately.. I'm not sure if it's a virus or hacked in or a web brower matter..
Should I go to the cookies/histories in the safari setting and have it cleared out? Will that help resolve that??
And what does the advance-setting of the clearing the website data does? Sorry, I'm not familiar.. what's is that used for? Should I use that feature as well?? Thank you!

This indicates corrupt files.
A restore should resolve.
