Question about DB lock level

From the manual we can only select row level locking / table level locking ( LockLevel=0/1)
Can I make it don't lock at all for READ only DB?

Through configuration you can select row level locking (LockLevel=0, the default) or database level locking (LockLevel=1). Datase level locking locks the entire database in eXclusive mode for every transaction and so effectively serialises access to the entire database. Table level locking can be influenced only by using optimiser hints and in general you mostly will only actually see table level locks if you use SERIALIZEABLE isolation.
What is it that you want to accomplish? It's not 100% clear to me from your original question?

Question about setting track level

Hi I finally got my new macbook pro and moto 8 pre and have just today tried a bit of recording just to get used to it. I am at the moment using garage band. I have a question about track levels. In Garage Band when I select a track to record there is a slider for input level or an option of clicking the automatic level control. But for some reason they are both just that color of grey you get when something can not be selected on a computer. How do I activate this? It's strange as I did actually manage to record the track, I just can't seem to really adjust the level. I thought maybe it has to do with the motu and I can only select the track level there, and that garage band level setting are (rightfully) disabled? Maybe that's what I should be doing, but just a bit confused. Anyway, thanks in advance for whoever takes the time to help out a newbie.

Ah, ok. Good to know. Thanks for the info.

Question about /var/lock/subsys/dbora

Hello,
I've been having a problem where ./dbora stop is not completely shutting down the database. I've done some debigging and discovered that this is because there is no /var/lock/subsys/dbora file. I've seen this file created in a lot of sample dbora scripts, ie
touch /var/lock/subsys/dbora
My question is why is this? Why does the file not get created when Oracle is started?
I'm on Oracle 10G.
thanks very much

dbstart and dbshut are oracle supplied files which we use to start and stop the database. We create a small shell script which get placed in rc.d and that file called those dbstart/shut files to start and stop oracle services at boot time. "touch /var/lock/subsys/dbora" is an extra login which WE put in our shell script and it should not have any relation with starting and stopping the services. It totally depends on the shell script written by the DBA. I have this piece of code in my startup script and I can see this file on my system but even if i can't its not going to stop working.
You first of all make sure what permission do you have on /var/lock/subsys

Question about an entry level java programmer

i was curious that if i do find a job in java as an entry level what kind of programming can i expect? i am sure some of the members over here were hired as an entry level. can you share your ideas with me? like any projects etc...

What is your background in education? I don't know how much you know of Java, but that won't be the only thing they base their choice on. You barely ever have a project that uses exclusively java. Make sure you know basics of working with databases, different operating systems...
The most important thing is that you can sell whatever you know as usefull for the job they have for you! Prepare yourself well for an interview. If you have the time, picture the type of work you expect from a vacancy. Ask yourself what technologies will be needed for that particular job and make sure you do at least know a little about them. Make sure you adapt your responses to the type of interviewer, type of company. In addition to that, don't tell people you know more than you do!
Get some understanding on OO concepts.This would be a very important thing for some, but totally unnecessary to others. For me this is quite important! If your interviewer is a manager type, he won't be able to follow what you're talking about if you start talking about design principles! If your interviewer is a techie, then this is a good thing to show.
JCP certification would be handy..From my experience this isn't a minimum requirement to get in. If the company values certificates, you can always use it afterwards to prove your dedication and get a raise once you're in. ;-)
Further knowledge in Web components and Enterprice components (eg EJB) will be pluses.Again viewed from the 'make it sellable' side. If you come bragging that you're a Spring expert and your company is against open source frameworks, that won't be a point in your advantage.

Question about Table Locks

Hi All,
Is there any Oracle defined table/place from where we can know the details about Tables that have been locked in the current session?
Thank you.

Hi ,
To know which all objects are locked, you can use the below query :-
COLUMN owner FORMAT A20
COLUMN username FORMAT A20
COLUMN object_owner FORMAT A20
COLUMN object_name FORMAT A30
COLUMN locked_mode FORMAT A15
SELECT b.session_id AS sid,
       NVL(b.oracle_username, '(oracle)') AS username,
       a.owner AS object_owner,
       a.object_name,
       Decode(b.locked_mode, 0, 'None',
                             1, 'Null (NULL)',
                             2, 'Row-S (SS)',
                             3, 'Row-X (SX)',
                             4, 'Share (S)',
                             5, 'S/Row-X (SSX)',
                             6, 'Exclusive (X)',
                             b.locked_mode) locked_mode,
       b.os_user_name
FROM   dba_objects a,
       v$locked_object b
WHERE a.object_id = b.object_id
ORDER BY 1, 2, 3, 4;Anand

Questions about activation locks? Help?

Okay so I bought an iphone 5 off kijiji and everything is fine so far but I have a few questions. It says "SIM required" and I don't have a SIM card yet as I'm getting one next week. I'm not sure if it's activation locked. My questions is Does the activation lock alert pop up before it asks for SIM? Or after when I've put in my SIM?
Hopefully that makes sense because I don't have a SIM yet and I don't know how else to check if its activation locked. Please reply.

It checks for activation lock when you attempt to activate the phone with a SIM card in it.

Quick question about Auto-lock settings

Hello all,
I recently was able to sync my office email account to my iPhone using Microsoft Exchance active sync. The problem as I understand from searching through different posts, is that I can no longer set my Auto-lock setting to "Never" because of this, only 5 minutes (sort of a security thing as far as I can tell).
The reason I am trying to do this is that I like to use one or two of the GPS golf apps out there, and they stay dialed in if the phone doesn't "sleep" while I am playing a round, so I would like to keep it on the entire time.
Does anyone have any ideas of how I might be able to work around this issue in any way?
Responses are, as always, much appreciated!
Cheers,
Kev

More than likely, you could not simply delete the account. The thing is that the people who came up with the security protocols already thought of that. As an employee using a company cell phone, I could delete my account, access features or information my company restricts and then readd the account, thus bypassing security protocols.
In addition, I might have other sensitive company information (in the form of contacts, documents, notes, etc) that would still be on the phone even if I delete my exchange account. Without autolock, people would still have access to this data even if I delete the account.
To prevent this type of abuse, when an exchange account is added, it installs a set of restrictions and protocols to the phone. Those protocols can, at the discretion of IT, be non alterable and non removable, even when the exchange account is deleted. This prevents people from abusing the loophole you are describing.
Similarly, simply switching to another email account will not bypass them - these protocols are now part of how your phone acts and can not be changed without wiping it back to factory settings.

Question about object lock

Hello everyone,
I want to know which method owns the lock of a specific object (some of my methods are blocked because they can not achieve the lock of a specific object, and I am wondering which method owns the lock to solve the deadlock issue). Does anyone know how to get the information?
Thanks in advance,
George

Thanks Feamar,
U should not think of a method as having a lock,
rather than that u should think of a piece of
synchronized code to have the lock on an object.
U should try and find nested synchronization
statements in your code, those are risky and can lead
to deadlocks.
Good luckYour reply is very helpful. What means "nested synchronization statement" in your reply?
regards,
George

Question about setting guitar levels

Hi, I'm new at Garageband so bear with me. I just bought an Avid Recording Studio Fast Track USB interface to hook up my guitar. It's got 3 knobs on the top- Mic Gain, Guitar Gain and Output. (Mic Gain is for the XLR input, Guitar Gain for the 1/4 inch input, and then the output). When I hook it up in Garageband and click on the back of an amp, the recording level slider is grayed out and I can't adjust it. How do I get the proper guitar level so I'm getting maximum sound with no noise and no clipping? Do I adjust the volume slider on the track? I assumed that was just for volume and not the actual recording level.
Any help is appreciated, thanks!

N8: question about screen lock during calling

I really like my N8 but there's annoying thing. While I'm calling, in the most cases the screen turns on and with my face I press the buttons on it. So I always end my calls unwantedly or turn on the speakers...
Is there any solution for that? I've not found any settings or software for that yet.

Sounds like the proximity sensor is faulty on your phone. You should have it checked out at your local Nokia Care point.

About pessimistick lock in Oracle

Hello,
I have some questions about pessimistick lock in Oracle:
I know if i do a SELECT..FOR UPDATE statement, those records are locked, and just me can opperate on them.. but me - WHO? How i'm identified in Oracle? If i do a SELECT..FOR UPDATE select in an A procedure, then i call the update procedure B, how can i know that both calls belongs to the same user? If someone tries to update the same records, how the server knows if that person is allowed to make those updates or not? because everyone uses the same connection string.. isn't it?
Probably it works if i make a SELECT..FOR UPDATE and i make the effective update in that procedure, but this means that the Business Logic is in that procedure..
Please correct me if i'm wrong somewhere and clarify me.
Thanks!

By default the other session has to wait (no error message):
From SQL Reference SELECT section: http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_10002.htm#SQLRF01702
>
NOWAIT | WAIT
The NOWAIT and WAIT clauses let you tell the database how to proceed if the SELECT statement attempts to lock a row that is locked by another user.
Specify NOWAIT to return control to you immediately if a lock exists.
Specify WAIT to instruct the database to wait integer seconds for the row to become available and then return control to you.
If you specify neither WAIT nor NOWAIT, then the database waits until the row is available and then returns the results of the SELECT statement.

I am an HP employee.

My HP, purchased in June 2012, died on Saturday. I was working in recently installed Photoshop, walked away from my computer to answer the phone and when I came back the screen was blank. When I turned it on, I got a Windows Error Recovery message. The computer was locked and wouldn't let me move the arrow keys up or down and hitting f8 didn't do anything.
I'm not happy with HP. Any suggestions?

Some questions about Muse

First of all, I would like to say that I am very impressed with how well Muse works and how easy it was to create a website that satisfies me. Before I started a daily updated website I thought I would encounter many problems I will not be able to solve. I have only had a few minor issues which I would like to share with you.
The most problems I have with a horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html). Marking and copying of a text is possible only on the last (top) layer of a document. The same situation is with widgets or anything connected with rollover state - it does not work. In the above example it would be perfect to use a composition/tooltip widget on the first page. Unfortunately, you cannot even move the cursor into it.
It would be helpful to have an option of rolling a mouse to an anchor (like in here http://www.play.pl/super-smartfony/lg-nexus-5.html and here http://www.thepetedesign.com/demos/onepage_scroll_demo.html). I mean any action of a mouse wheel would make a move to another anchor/screen. It would make navigation of my site very easy.
Is it possible to create a widget with a function next anchor/previous anchor? Currently, in the menu every button must be connected to a different anchor for the menu to be functional.
A question about Adobe Muse. Is it possible to create panels in different columns? It would make it easier to go through all the sophisticated program functions.
The hits from Facebook have sometimes very long links, eg.
(http://www.leftlane.pl/sty14/mclaren-p1-nowy-krol-nurburgring.html?fb_action_ids=143235557 3667782&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582). If such a link is activated, the anchors in the menu do not work on any page. I mean the backlight of an active state, which helps the user to find out where on page they currently are. The problem also occurs when in the name of a html file polish fonts exist. And sometimes the dots does not work without any reason, mostly in the main page, sometimes in the cooperation page either (http://www.leftlane.pl/wspolpraca/). In the first case (on main page), I do not know why. I have checked if they did not drop into a state button by accident, moved them among the layers, numbered them from scratch and it did not help. In the cooperation page, the first anchor does not work if it is in Y axle set at 0. If I move it right direction- everything is ok.
The text frame with background fill does not change text color in overlay state (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html). I mean a source button at the beginning of every text. I would like a dark text and a light layer in a rollover, but the text after export and moving cursor into it does not change color for some reason.
I was not sure whether to keep everything (whole website) in one Muse file (but I may be mistaken?). I have decided to divide it into months. Everyone is in a different Muse file. If something goes wrong, I will not have any trouble with an upload of a whole site, which is going to get bigger and bigger.
The problem is that every file has two master pages. Everything works well up to the moment when I realize how many times I have to make changes in upper menu when I need to add something there. I have already 5 files, every with 2 masters. Is there any way to solve this problem? Maybe something to do with Business Catalyst, where I could connect a menu to every subpage independently, deleting it from Muse file? Doing so I would be able to edit it everywhere from one place. It would make my work much easier, but I have no idea jendak how to do it.
The comments Disqus do not load, especially at horizontal layouts (http://www.leftlane.pl/sty14/2014-infiniti-q50-eau-rouge-concept.html). I have exchanged some mails and screenshots with Disqus help. I have sent them a screenshot where the comments are not loaded, because they almost never load. They have replied that it works at their place even with attached screenshot. I have a hard time to discuss it, because it does not work with me and with my friends either. Maybe you could fix it? I would not like to end up with awful facebook comments ;). The problem is with Firefox on PC and Mac. Chrome, Safari and Opera work ok.
YouTube movie level layouts do not work well with IE11 and Safari 7 (http://www.leftlane.pl/sty14/wypadki-drogowe--004.html). The background should roll left, but in the above mentioned browsers it jumps up. Moreover the scrolling with menu dots is not fluent on Firefox, but I guess it is due to Firefox issues? The same layout but in vertical version rolls fluently in Firefox (http://www.leftlane.pl/sty14/polskie-wypadki--005.html).
Now, viewing the website on new smartphones and tablets. I know it is not a mobile/tablet layout, but I tried to make it possible to be used on mobile hardware with HD (1280) display. I mean most of all horizontal layouts (http://www.leftlane.pl/sty14/2015-hyundai-genesis.html), where If we want to roll left, we need to roll down. Is there a way to make it possible to move the finger the direction in which the layout goes?
On Android phones (Nexus 4, Android 4.4.2, Chrome 32) the fade away background effect does not work, although I have spent a lot of time over it (http://www.leftlane.pl/lut14/koniec-produkcji-elektrycznego-renault-fluence-ze!.html). It is ok on PC, but on the phone it does not look good. A whole picture moves from a lower layer instead of an edge which spoils everything.
This layout does not look good on Android (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html#a07). The background does not fill the whole width of a page. There are also problems with a photo gallery, where full screen pictures should fill more of a screen.
Is it possible to make an option of scroll effects/motions for a fullscreen slideshow widget thumbnails (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06)? It would help me with designing layouts. Currently, it can go from a bottom of a page at x1 speed or emerge (like in this layout) by changing opacity. Something more will be needed, I suppose.
Sometimes the pictures from gallery (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06 download very slowly. The website is hosted at Business Catalyst. I cannot state when exactly it happens, most of the time it works ok.
I really like layouts like this (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a03). On the top is a description and a main text, and the picture is a filled object with a hold set at the bottom edge. That is why there is a nice effect of a filling a whole screen- nevertheless the resolution that is set. It works perfect on PC, but on Android the picture goes beyond the screen. You can do something about it?
In horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html) holding of a filling object does not work. Everything is always held to upper edge of a screen regardless the settings. Possibility of holding the picture to the bottom edge or center would make my work much easier.
According to UE regulations we have to inform about the cookies. I do not know how to do it in Muse. I mean, when the message shows up one time and is accepted, there would be no need to show it again and again during another visit on the website. Is there any way to do it? Is there any widget for it maybe?
The YouTube widget sometimes changes size just like that. It is so when the miniature of the movie does not load, and the widget is set to stroke (in our case 4 pixels, rounded to 1 pixel). As I remember ( in case of a load error) it extends for 8 pixels wide.
Last but not least - we use the cheapest hosting plan in Business Catalyst. The monthly bandwidth is enough, although we have a lot of pictures and we worried about it at first. Yet we are running out of the disk storage very quickly. We have used more than a half of a 1 GB after a month. We do not want to change BC for a different one, because we like the way it is connected with Muse. But we do not want to buy the most expensive package - but only this one has more disk space. We do not need any other of these functions and it would devastate our budget. Do we have any other option?
I’m using Adobe Muse 7.2 on OS X 10.9.1.
and I'm sending Muse file to <[email protected]>

Unfortunatley, there is no way to get a code view in Muse. I know quite a few people requested it in the previous forum, but not really sure where that ended up. Also, you may not want to bring the html into DW unless you only have 1 or 2 small changes 2 make. Two reasons. First, it isnt backwards compatible, so if you are planning on updating that site in Muse, you will need to make those changes in DW everytime you update. Second, by all accounts the HTML that Muse puts out is not pretty or easy to work with. Unlike you, I am code averse, but there was a lenghty discussion on the previous forum on this topic. I know they were striving to make it better with every release, just not sure where it is at this point.
Dont think I am reading that second question right, but there was a ton of info on that old site. You may want to take a look there, people posted a ton of great unique solutions, so it worth a look.
Here is the link to the old forums- http://support.muse.adobe.com/muse

Questions about using Bitlocker without TPM

We currently use Bitlocker to encrypt our Windows 7 computers with TPM. Now we are looking at encrypting some Windows 7 computers without a TPM. I see how to change the group policy setting to allow Bitlocker without a TPM. I have looked at a lot of other
threads and I have a few questions about how the Bitlocker without TPM works.
1) I see a USB drive containing a key is required for Bitlocker configurations without a TPM, say the end user loses this USB drive, what are the recovery options for their computer?
This article seems to indicate that without the USB drive connected, you are unable to even access recovery options http://blogs.technet.com/b/hugofe/archive/2010/10/29/bitlocker-without-tpm.aspx
We have recovery backed up to AD when Bitlocker is enabled, but how could we do this recovery on a computer on computer where it's USB is lost? Would we have to remove the HD itself and attach it to another computer to access?
2) After enabling Bitlocker on a computer without a TPM and using the USB Drive for the key, is there a way to also add a PIN or password protection at bootup?

Hi,
Sorry for my dilatory reply,
Configuring a startup key is another method to enable a higher level of security with the TPM. The startup key is a key stored on a USB flash drive, and the USB flash drive must be inserted every time the computer starts. The startup key is used to provide
another factor of authentication in conjunction with TPM authentication. To use a USB flash drive as a startup key, the USB flash drive must be formatted by using the NTFS, FAT, or FAT32 file system.
You must have a startup key to use BitLocker on a non-TPM computer.
From: http://technet.microsoft.com/de-de/library/ee449438(v=ws.10).aspx#BKMK_Key
For more Q&A about BitLocker, you can refer to the link above.
hope this is helpful.
