"Logging level" - what exactly is logged at a given level?

Wanting to log activity from an Airport Express I have been searching for a list of which types of events actually are logged depending on the "Logging level" selected in the "Airport Admin Utility" software at the "Airport" tab, "Base Station Options...", "Logging/NTP" tab.
A link to such a list or any other help on this issue is greatly appreciated.

What exactly is Redo log buffer?

I know that Redo log buffer is a part of SGA and it sotores each and every change in it. But i want to know whether it stores all the updates and other changes as it is stored in DB Buffer Cache.? Or if not what exactly is sotored in it and when...?
null

Hi,
Redo Log Buffers are part of SGA and they store each and every entry that is made in the DB.
This is also stored in the Redo Log FIles. This information is used during recovery of a Crashed DB.
A Redo Log does not Store the Data but oinly the Stmt. that was executed in the DB.
A DB Buffer Stores data and not the command.
If u need more information Pls Refer to The Oracle 8 Concepts on the Oracle Documentation.
Hope this helps.

What exactly is contained in "Components Level" output of Harmonic distortion Analyzer VI?

The Components Level output of the Harmonic Distortion Analyzer VI is described in the help file:
"components level contains the array of amplitudes of the measured harmonics in volts if the signal in is in volts. The array index is the harmonic number including 0 (DC), 1 (fundamental), 2 (second harmonic),... n (nth harmonic), up to and including the highest harmonic."
However, why is there more than one measurement of each harmonic included in the array? Specifically, probing the wire says it's a 1D array of clusters with one element each, the clusters are 1D array of doubles.
So, multiple double values are associate with each harmonic. What exactly do these values signify? Creating an indicator on the wire (as below, "component levels" - the indicator is right off the hamonic analyzer, not the bit below it with the index array/unbundle stuff) shows four of the numbers in the array. Sometimes the fourth or even third are greyed out, meaning that the array varies in size from one iteration of my while loop to the next.
I would think that at the least, magnitude and phase would be included, but experimentation with a source that has 60Hz, plus a harmonic (7th, or 15th, etc) at -20 degrees doesnt' correlate with the data. I don't see "-20" or the radian equivilant at all.
Any ideas or a pointer to more detailed information than the help file?

Hi Xooch,
I'm not sure that I totally understand what you're asking about. When I went to recreate this, I used both a cluster indicator and a double array that had been indexed and unbundled from the original output.
What do you mean by "multiple double values"? I only saw one value for each harmonic, so I'd like to clarify that.
I'd also like to clarify what types of values are being passed into the function and how many channels are being used. I think these answers may be helpful in finding out what's going on with the cluster greying out some of the values. I'd also like to verify that these values are being greyed out while the VI is running through different iterations of the loop as opposed to when the program has stopped and restarted.

What exactly is a "low-level exception occurred in: ImporterFastMPEG?"

I've been importing several HDV video files (m2t files) from my Sony HDR-DR60 HDD unit into Premiere Pro CS6 on my Macbook Pro w/ Retina Display. I noticed that this error popped up for 3 files: "A low-level exception occurred in: ImporterFastMPEG (Importer)" What exactly is happening here? What does that mean? Those video files appeared with small "?" icons next to their names in the bin. I attempted to import them again, but I was either given the same error message or only the first few seconds of the file would import. For example, one file is 645MB and is a little over 3 minutes long. Now when I try to import this file, it shows as being only 19 seconds in length.
Now here's where it gets perplexing: I took that same file and fired up my decommisioned Windows PC with an old installation of Premiere Pro CS5.5, and it imported perfectly without a problem.
I found a very slow work-around where I converted the m2t file into an uncompressed Quicktime MOV, but I'd like to find out what the root cause is and why I'm getting this error for these few files. I've done a lot of shooting this week, and I haven't had a problem with any other files from my HDR-60.
So, is this a Mac/Apple problem, a Premiere CS6 problem, or are those particular files just randomly weird? Google searches have not yielded anything useful which is why I'm asking here.

What exactly is the advantage of VPN?

I work in an architectural office of about 15 people. We've always had access to our wiki, files and calendars when out of the office.
Currently we have a Standard setup of Leopard Server with the following services: iChat (using just a private local domain), iCal (with all calendars delegated to one another), AFP file server (3 different groups) and Wiki Server.
What exactly would the advantage be to us of VPN, over simply connecting to a file server via "Connect to Server...", accessing our Wiki via the office IP address, and subscribing directly to our calendars from home?

VPN: Virtual Private Network.
Virtual: implemented without needing specific hardware; uses existing networking hardware and connections. Non-virtual ("real" or "physical") private networks typically involve dragging network wires around or broadcasting signals of your own, or leasing T1 or SONET lines and other such gear from a communications vendor.
Private: A private network is (preferably) difficult to eavesdrop from the open WiFi at the coffee shop, easier to control access. Non-private networks are also known as open networks, and that ftp or telnet or imap/pop password you just entered can be read by others on the same network. That, and the entire contents of the mail messages you have sent and received over the open network are also accessible.
Some private networks are less secure than others. The WEP-based security provided by some WiFi networks is now usually considered to be analogous to a wide-open WiFi; WEP is quite weak, and tools to break it are widely available. WPA is rather better here, and anyone using WEP should move to WPA, or better. (qv: the TJX credit card data exposure was reportedly due to the use of WEP.)
Most VPNs also have some form of authentication; a certificate, smartcard or token card, or other such challenge. Passwords are one of the weakest mechanisms here, but there are VPNs that use just passwords.
+I guess too, there is some additional functionality added. For instance if you're logged into the VPN with a work laptop, presumably if you update your server-based calendar it will update the server as well.+
No. A VPN is and should be assumed nothing more than a network connection. The difference is in the degree of privacy provided. Beyond the encryption and authentication typically inherent, VPNs do not add application-level features over what an open network connection might provide.
An ssh tunnel is a specific form of VPN, and does reasonably well at providing security and at avoiding exposing your password and your data.
Network: as with open networks, VPNs can be used to allow client systems to access a network, or to bridge two or more networks together. VPNs can also provide a reasonable way to manage the connections between these networks, or a client connecting into a network. For the purposes of discussing connectivity, a VPN is another form of a network connection.

What exactly does the global switch command line do ?

Hello All
Just foraging in the dark world of APP-V. I have a question which I cannot find answer for through google.
There are powershell commands to publish an APP-V application globally. What exactly does the global switch do ?
I understand it makes the application available to everyone on the machine for anyone who logs onto that machine.
However in the absence of this global switch the application is still available to all users who logon to that particular machine. So what exactly is the reason for using the global switch ?
Thanks

Correct, the global switch makes the application accessable for all users logging on to that system.
This feature is required for some packages, like Office. But it is ofter used for applications used by everyone, like Adobe Reader.
However in the absence of this global switch the application is still available to all users who logon to that particular machine. So what exactly is the reason for using the global switch ?
A package can be added to the system but until it is published a user cannot start it. They won't see any shortcuts in their startmenu/desktop/etc.
So after you added the package to the system, it must be published to a user or globally (every user) to start it.

What exactly are the cron scripts doing?

Hi,
Hope the subject says it all: I have searched but not found a detailed explanation as what the cron scripts (daily, weekly, monthly) actually do, and if the utilities (Onyx, Cocktail, Xupport, etc) are doing exactly the same.
Can someone point to a site or explain?
TIA
Dan

Hi Dan,
(in addition to Barry's reply)
Yes,
1) running the Daily, the Weekly and the Monthly tasks manually with an utility, or
2) running them yourself with the
sudo periodic daily
sudo periodic weekly
sudo periodic monthly
Terminal commands
(or this one: sudo periodic daily weekly monthly), or
3) leaving your computer running 24/7/365 so that they run automatically,
all three ways do exactly the same thing.
--> To see what they do exactly, the best way is to open Console, and in the /var/log section, look for "daily.out", "weekly.out" and "monthly.out".
What exactly are the "cron scripts" doing?
(Periodic tasks)
In Console, you'll find a lot of different files that grow with more and more information every minute, even every second for some of them.
The three Periodic tasks regularly rearrange them and compresses them so that they don't take too much disk space.
They also rebuild some system database so that the data never gets unusable by the system.

I am confused about Icloud. I have a 5 year old Macbook, a 2 year old macbook and a 5 year old mac mini. What exactly do I need to do to get all this connected via Icloud. I also have an Iphone 3G. Help please!

I am confused about Icloud. I have a 5 year old Macbook, a 2 year old macbook and a 5 year old mac mini. What exactly do I need to do to get all this connected via Icloud. I also have an Iphone 3G. Help please! Also, I still don't understand exactly what the benefits are. At the moment it seems a lot of hassle to change a system that's been working perfectly well and that I'm very happy with. I'm not at all sure whether the mac mini (1.66 GHz INtel Core Duo) can be brought up to the relevant spec to run ICloud. Any thoughts?

There are two aspects to iCloud. One is simply getting an account, or migrating a mobileme account to iCloud. The second part is using the various features of iCloud to sync contacts, calendars, use music match or photo sharing, and store iWorks documents.
First to get an iCloud account:
If you have a mobileme account, you can migrate by simply logging onto www.icloud.com (ignore any references to Lion and just click through to complete the migration). If you have OS X Lion or an iOS 5 mobile device, you can create an iCloud account on that device using any valid AppleID.
Once you have an account, you can use JUST the mail account if you wishi - it is a standard IMAP account so you would set it up like any other IMAP email account you have, in whatever client program you use to read email.
To use the OTHER feautes of iCloud, your computers will have to be running OS X Lion (10.7). Your iPhone 3G will never be able to use iCloud as it cannot run iOS 5 (you need a min. of an iPhone 3GS to run iOS 5).
The requirements for OS X Lion are here - http://www.apple.com/macosx/specs.html You need a min. of a Core 2 duo processor so you mini is not capable of running Lion.
So, in your case, the single reasons for iCloud would be if you have a mobileme account, then use the online www.icloud.com to migrate your account so you do not lose your @me.com email address. You can use iCloud email (without using any other iCloud features) by setting it up as IMAP mail with these settings - http://support.apple.com/kb/HT4864
If you want an iCloud account and do NOT already have a mobileme account, you will need to upgrade one machine at least to Lion in order to be able to create an iCloud account.

What exactly do the national instruments citadel nt service and the lookout citadel nt service run

We have WhatsUp monitoring software set to monitor NI Lookout and the PC it is on. It pings the PC, and polls the Lookout Citadel Server NT service. If either one fails, WhatsUp sends an email notification. I was under the impression if the Lookout Citadel Server service is down, then NI Lookout won't graph or record data, but that's not the case. If I shut Lookout Citadel Server or National Instruments Citadel Server down, NI Lookout still graphs and records. What exactly do these two services run?
Also, is there a possibility that NI Lookout can be viewed through palm OS software, like a Blackberry?

Lookout Citadel Server is for Citadel 4, which is used by Lookout 5 and DSC 7.
NI Citadel is for Citadel 5, used by Lookout 6 and DSC 8.
If Citadel is stopped, Lookout will start it up automatically when launched. But if Citadel is stopped when Lookout is running, there might be some unexpected issues, although the data logging seems to be working well.
So I strongely recommend you not to stop those Citadel service when Lookout is running.
Lookout cannot be running on palm OS.

What exactly happens when datafile is put in backup mode ?

Dear Friend,
i want to know what exactly happens when a datafile is put in backup mode ?
that is what happens between Begin Backup ........................... end backup
with regards.

When u start hot backup via 'alter tablespace begin backup', the tablespace headers are marked as such. The dirty data buffers that belong to the database files are written out to the files and the datafiles are check pointed. The headers are updated with SCN @ the time the backup commences. It is the data file headers that were not updated until the 'alter tablespace end backup' is issued.
The database files still continue to be read and updated. Recovery will commence from the scn written at the commencement of the backup and it is the changes written to the redo\archive logs during the backup that are rolled forward during recovery

What exactly is a wrapper class?

In so far as Integer, Byte, Double et al. are concerned I understand that those wrapper classes are a way to handle primitive types as objects. But I've come across references to wrapper classes in documentation and other technical articles and I don't think I really understand what they are really used for. Why do you need a wrapper class for an object?
Could someone shed me some light on this issue?
Thanks,
John

An instance of a wrapper class holds a pointer to and instance of some other class or interface and provides access to it, typically supplying methods equivalent to all the methods of the underlying type.
The basic wrapper class a functional replacement for the underlying object.
When you're passed an object from some code outside your control you often don't know what exact class it is, or have access to it's class definition.
A wrapper object allows you to modify the functionality of such an object. You can extend the wrapper class, for example, adding extra methods. Or you can modify the methods, for example to provide logging of calls made.
As a concrete example, I have a wrapper class LoggedConnection which wraps a java.sql.Connection object. It also implements java.sql.Connection. If you ask a LoggedConnection for a Statement or PreparedStatement it fetches the appropriate object and returns a wrapped version which logs the SQL and the execution times etc..
My "get me a connection" routine can return either a raw Connection or a LoggedConnection according to whether a SQL log file is provided.
The main program doesn't need to know if it's using a genuine Connection object or the wrapped version.
Part of the definition would look like:
public class LoggedConnection implements Connection {
private Connection wrappee;
public LoggedConnection(Connection con) {
wrapee = con;
public createStatement() throws SQLExeception {
return new LoggedStatement(wrappee.createStatement())
}(Of course this was tedious to write by hand because Connection has so many methods, all of which the wrapper must implement. Later I wrote a java program to generate Wrapper classes).

What exactly is a context?

There is something that is kind of messing me up... I do not exactly understand what a "context" is... I am starting to read J2EE material, and there are all kinds of context objects, usually associated with some other kind of object.
What exactly is the context object in relation to the other object?
Thanks,
PM

Have a look at the API.
Example:
public interface SessionContext
extends EJBContext
The SessionContext interface provides access to the runtime session context that the container provides for a session enterprise Bean instance. The container passes the SessionContext interface to an instance after the instance has been created. The session context remains associated with the instance for the lifetime of the instance.
Or...
public interface ServletContext
Defines a set of methods that a servlet uses to communicate with its servlet container, for example, to get the MIME type of a file, dispatch requests, or write to a log file.
There is one context per "web application" per Java Virtual Machine. (A "web application" is a collection of servlets and content installed under a specific subset of the server's URL namespace such as /catalog and possibly installed via a .war file.)

What exactly is the difference between enqueue,latch & lock

Can someone explain in simple words (with example if possible) what exactly is the difference between enqueue,latch & lock?
I have gone through documentation & other links,but just not able to figure out the exact & clear difference between these three..
Cheers,
Kunwar

In addition to links provided by Sb and nice explanations by Aman, i would like to add below :
1.Latches and enqueues are lightweight serialization devices used to coordinate multi-user access to
shared data structures, objects and files.
Latches are locks that are held for extremely short periods of time, for example the time it takes to modify
an in-memory data structure. They are used to protect certain memory structures, such as the database
block buffer cache or the library cache in the shared pool (as described in Chapter 2, Architecture). Latches
are typically requested internally in a ‘willing to wait’ mode. This means that if the latch is not available,
the requesting session will sleep for a short period of time and retry the operation later. Other latches may
be requested in an ‘immediate’ mode, meaning that the process will go do something else rather than sit
and wait for the latch to become available. Since many requestors may be waiting for a latch at the same
time, you may see some processes waiting longer than others. Latches are assigned rather randomly, based
on the ‘luck of the draw’, if you will. Whichever session asks for a latch right after it was released will get it.
There is no line of latch waiters, just a ‘mob’ of waiters constantly retrying.
Oracle uses atomic instructions like ‘test and set’ for operating on latches. Since the instructions to set
and free latches are atomic, the operating system itself guarantees that only one process gets it. Since it
is only one instruction, it can be quite fast. Latches are held for short periods of time and provide a
mechanism for clean-up in case a latch holder ‘dies’ abnormally while holding it. This cleaning up
process would be performed by PMON.
Enqueues are another, more sophisticated, serialization device, used when updating rows in a database
table, fro example. They differ from latches in that they allow the requestor to ‘queue up’ and wait for
the resource. With a latch request, the requestor is told right away whether they got the latch or not.
With an enqueue, the requestor will be blocked until they actually attain it. As such, they are not as fast
as a latch can be, but they do provided functionality over and above that which a latch can offer.
Enqueues may be obtained at various levels, so you can have many ‘share’ locks and locks with various
degrees of ‘shareability’.

What exactly does am.invokeMethod() do?

Can any one please explain what exactly does this am.invokeMethod() do
and I would like to ask about the setForwardURL also.
regards
Ram

Hello,
setForwardURL() method is used to call another page from current page.
here is the signature of the method..
void setForceForwardURL(String url,
String functionName,
byte menuContextAction,
String menuName,
com.sun.java.util.collections.HashMap parameters,
boolean retainAM,
String addBreadCrumb,
byte messagingLevel);
Sequence of parameters are very important and you should not change it.
Menu Context - This paramter determines the display of "Menus" on top of the page.
Eg. In Iprocuremet you would have seen "shopping", "Requistions", "Receipts" etc
This menu comes from AOL menus and functions. Hence while navigating from one page to another you have to tell the OAF whether you want to keep the existing menu or reset to new menus or remove the menus etc.
Bread crumb is a small back navigation link that gets added to the top of the page below the Menus. It allows the user to navigate back to previously visted pages.
messaging LeveL - Used to determine if the forward should be cancelled if messages or exceptions of level Error, Warning, Confirmation, or Information are found. Note all messages present will be shown regardless of the level.
Eg: if you have said OAException.WARNING in this parameter, then the page navigation will be for any warnings generated with in the page
