Logic refresher course questions

I haven't used Logic since 4.x, and am just now trying to setup a new Logic system..... basic questions:
1 - I would have thought that the audio format would be decided by now but it appears not..... what is the difference/benefit of SDII vs. AIFF?
2 - When doing new sound sampling, what do you try and target as a DB level?
3 - Say your tempo is 75bpm, is it better to say put logic at 150bpm so that the grid resolution is finer (this is a dumb question but I remember having issues with this way back, I am probably missing the "set grid resolution button")?

1 - I would have thought that the audio format would be decided by now but it appears not..... what is the difference/benefit of SDII vs. AIFF?
there is no huge difference other than SDII can't usually be read by windows machines. SDII will also save region information to the audio file. nowadays, aif files save loop information which is more useful in the main.
2 - When doing new sound sampling, what do you try and target as a DB level?
if by this you mean recording, you will find loads of people giving you advice about this, but basically you want your loudest sounds to be as close to 0.0 db as possible, in order for you to benefit from the greatest bit depth resolution. aim at about -3 to -1 db and record in 24bit. that makes the biggest difference to quailty.
3 - Say your tempo is 75bpm, is it better to say put logic at 150bpm so that the grid resolution is finer (this is a dumb question but I remember having issues with this way back, I am probably missing the "set grid resolution button")?
you can the grid resolution as fine as you want it - well unless your concerned about hemidemisemiquavers at such tempos. song length, in terms of beats has a bearing on logic. it advisable if your song is going to be really long to keep the tempos slower, prefer 75 bpm to 150bpm.

Merge/Refresh Workspace: Question concerning conflict resolution

hi!
thank's so far for answering our last question,now another question popped up during developing :)
we now have a state with our application where the user can select which objects to merge/refresh and finally commit these changes.
if there have been any conflicts he had to select a resolve operation for them. so far so good.
now, our method that performs the merging looks (no surprise) something like that: (the numbers are markers, used later on)
(1)
beginResolve();
do a few resolveConflicts();
(*) commit;
commitResolve();
(2)
(3)
do_merge/refresh_operations_of_death_in_correct_order();
(4)
ok, first question is concerning the line with the (*).
it seems we cannot call commitResolve() when there is an open transaction? as we run a spring managed application we first had it that way, that all of the above lines were executed within on transaction (that is, the complete merge/refresh operation going from (1) to (4)).
that didn't work, as we got exceptions on commitResolve(), that there is an open database transaction. is that because of the transaction wrapping the complete method? or did we do something else wrong?
now we split the method in two parts: one for the conflict resolution ((1) to (2) and one for the rest ((3) to (4)), both running within a transaction now. that works.
however, I feel a little bit unsafe with that, questions are:
if the first part runs in an own transaction and is commited: does the commitResolve() actually write data? or is that just something temporary on a per-session base? because, if something fails in the second part ((3) to (4)) then the transaction of that part of course rolls back fine, but the result of the conflict resolve part is probably still there? could we then, somewhere in the exception handling of the second transaction, call rollbackResolve()? or does it always have to happen within a conflict resolution session, that means, within (1) to (2)? the docs state the latter, but we're not really sure.
if something fails for whatever reason during the actual merge/refresh part, we need to make sure, that everything is rolled back to the state before
starting the whole process. it would be very dangerous to have some resolved conflicts hanging around that get merged/refreshed sometime later when the user doesn't even think about them.
btw, we also found the docs a bit inconsistent concerning conflict resolution. at some point it is explained, that after calling the resolveConflicts() a commit is needed, at another point this is left out and it is said, that one would just need to call commitResolve() afterwards and THEN a commit. it seems only the first explanation is correct (with another commit after the commitResolve()).
so, if you could clarify a bit on how a conflict resolution + merge/refresh session should look like concerning the management and scope of transactions, that would be really of great help and highly appreciated! the first tests worked fine with the way we have it working right now, but we always feel like there's a huge pitfall hiding somewhere ;)
best regards,
Andreas

Hi Ben,
after your explanation I agree. As the workspaces only carry the difference information of course there actually is no data in the child workspace if the object has been deleted in the parent.
I guess for the first we should not display this object to the user except when he's attempting to do a refresh, but not for a merge (or the other way round if the delete was done in the
child and NC in parent).
We didn't realize there is a rollbackTable with a WHERE clause, quite nice! Still, nothing practicable for us as we can't really know when a user might want to undo a delete and thus
which savepoint to use.
Reinserting would work, yes. We even tried that once for another scenario. Though in our case it would be important that the object also gets the same PK again, which is possible but still
feels like an ugly hack :-) Anyway, back to topic.
For the second scenario I was unfortunately mixing some WM and our users' terminology, thus it was not 100% clear. Sorry for that. What I meant was the following:
1) create new object in child
2) merge this object to parent
2a) DIFF is clear now, everything OK
3) goto parent workspace, new object is there
4) modify the new object there
5) goto child workspace again
6) open differences-viewer of our application <- here I wrote the users do a refresh, I meant they are >planning< to do a refresh, but not actually did it yet
OK, at point 6) we now get the diff information from the DIFF view and have an U for the parent and an I for the child. After your explanations and thinking over it some time we realized, that
this of course is totally correct: the last change in the parent was the update, the last change in the child the insert.
As the current version of our differences-viewer more or less displays the information from the DIFF-views in a straight way, the user now sees, that the object was updated in parent and new/inserted in child,
because those are the last operations for this row in both of the workspaces. That's what I meant is not intuitive, especially if they did not do all the operations themselves like in our small example and within
the timespan of 2 minutes.
It seems, we have to build some more abstraction around our current process?
To us it seems there are two solutions to this "problem", correct us if we oversee something:
1) currently synchronization within our application is directional, so either merge or refresh (except for conflict resolution, where the user might also want to decide to keep the object from the target workspace)
Thus we simply can ignore the DiffCode for the target workspace, except for conflicts, where we easily get the information from the CONF views
EDIT: no, we cannot simply ignore the target diffcode :( After some more thinking we have the same problem as with a real bidirectional synchronization process.
2) on the long run we actually planned to provide a bidirectional merge-tool to the user. In that case it's not that easy, as there is no single target workspace.
We didn't go into details yet, but probably we would need to retrieve further information, like e.g. the change timestamps for the DIFF rows for child and parent?
Then we could see what was actually the last change and display only that (except for U/U conflicts, but then again we get that information from the CONF view)
Any hints on how to do something like that the best way?
EDIT: We think it boils down to the question: how can we know, which parts of the DIFF have already been handled in a merge/refresh before and which haven't?
And another question, this time concerning the original topic: conflict resolution.
Is it possible in some way to ignore conflicts during a merge or refresh? Our users will definitely need that. The only idea we came up with yet would be again to use a savepoint (as you suggested
already concerning error rollback), that is have a savepoint (e.g. for the last time the workspace was synchronized) and then "fake resolve" the conflict (use CHILD with resolveconflicts) but do not
include the row in the following mergeTable() call. After merging has succeeded, use rollbackTable() for that row to the previous savepoint. Would that work?
Thanks again and regards,
Andreas Schilling

Logic Loop Copyright Question

Hi all. My question is, are all of the loops provided in Logic, Garageband, or any of the Jampacks, free from copyright restrictions? Meaning when utilized for commercial purpose, do they need to be declared as samples, or is everything provided, basically up for grabs? Thanks!

I thought this was quite clear:
"2. Permitted License Uses and Restrictions.
This License allows you to install and use one copy of the Apple Software on a single Apple-labeled computer at a time. You may use the Apple and third party audio loop content (“Audio Content”), contained in or otherwise included with the Apple Software, on a royalty-free basis, to create your own original soundtracks for your video and audio projects.

Logical Switch design question...

I received a new server that has 4 NIC's.
I've seen alot of articles about seperating out the Management, Live Migration, Cluster, and Tenant traffic but it seems they are putting it under all the NIC's teamed.
So my questions are:
Is it better to dedicate a single NIC to management, single NIC to live migration, then TEAM the last two NIC's for tenant traffic?
Or is it better to TEAM all four NIC's and put them under one logical switch then create a virtual switch for Management, Live Migration, and Tenant traffic?
I am using multiple VLAN's for customers.

I went with a dedicate physical NIC for management and live migration and then teamed two NICs for VM traffic

ADF-JClient Refresh (Newbie question)

I've gotta believe this is an easy thing to do with ADF, yet after perusing the documentation I could find (most is struts oriented) I just can't seem to get this working and I'm sure somebody here has done it. Also I'm pretty green when it comes to this ADF stuff so hopefully I use all the right terms, etc.
I have a simple app, that hooks up to a EJB application using a session facade. I have an Order bean, and I have an order line item bean and as you may guess there is a 1-M relationship between the two.
I set up the page with all the ADF stuff, and basically both are displayed as JTables. When I go to add a line item I:
1)want to call the ADF operation to do so
2) refresh both tables with their appropriate data (orders has a total price item that needs to be incremented)
3) select the orders JTable's order record that corresponds to the line item I just inserted
4) select the lineItems JTable's line item record that I just inserted.
The way I currently try to do this, which doesn't quite work is:
1) call the ADF operation "addLineItem" passing it appropriate details
2) define an ActionBindingListener class that has an afterActionPerformed() method that:
a) calls panelBinding.execute() (to refresh the orders table)
b) calls ordersTable.changeSelection(x, y, false, false) to try and select the appropriate row in the orders table
c) calls "getLineItems" operation which looks at the row that ordersTable is pointing to to update the line items table
d) calls lineItemsTable.changeSelect(x, y, false, false) to select the appropriate row in the line items table
Doing this, after I add an item, I see the correct order get selected, but then the table seems to switch off of it and select the row at the top of the table (as if a refresh had been requested again). The odd thing is that sometimes the above logic seems to work. I'm thinking my problems probably stem from calling panelBinding.execute(), but I haven't found any other clear way to refresh the data without doing that. What am I doing wrong? or am I right and there is a bug with the refresh?
Any ideas/suggestions, no matter how stupid it may seem are appreciated. I think this is something simple, I'm convinced I've just missed something obvious.

I think I figured out my problem. The key was to not use the JTable.changeSelection() method to set my selection post update. I needed to set it on the the JUTableBinding via a using a NavigatableRowset, so I did something like:
void selectLineItemRecord(Long oid)
JUTableBinding tableBinding = (JUTableBinding) panelBinding.findControlBinding("lineItemList");
NavigatableRowIterator iter = tableBinding.getIteratorBinding().getNavigatableRowIterator();
if(oid != null)
for(int i = 0; i < iter.getRowCount(); i++)
Row row = iter.getRowAtRangeIndex(i);
if(oid.equals(row.getAttribute("oid")))
iter.setCurrentRow(row);
return;
// fall through if not found or oid doesn't exist
iter.reset();
This seems to work much better now. Now if I just need to figure out some scroll bar stuff and I should be all set.
FYI, the thread I garnered this information from is Re: JTable returning to previously selected row after executeQuery()

Data Guard Logical Standby DB Questions

Hi,
I am creating Oracle 9i Logical Standby database on AIX 5 on same server ( for
testing only ).
In Data Guard Manual ( PDF file page no : 86 ) it is said that
Step 4 Create a backup copy of the control file for the standby database. On the
primary database, create a backup copy of the control file for the standby database:
SQL> ALTER DATABASE BACKUP CONTROLFILE TO
2> '/disk1/oracle/oradata/payroll/standby/payroll3.ctl';
My Questions regarding this are
1. Does it missing "backup standby controlfile" word ? if not what is the use of
this control file ? Because as per this manual section 4.2.2 step no 1 and 2 I
have stopped the primary database and copied datafiles,logfiles and controlfiles
as specified which are having consistent stage.
2. On primary database I am mirroring 2 controlfiles at two diffrent locations.
On Standby Database I am going to keep same policy. Then on standby database do I have to copy this controlfile to two locations and rename datafiles or I have
to user controlfiles which I have backed up along with datafiles ?
3. Suppose my primary database is "infod" and standby database is "standby".
Then what should be value of log_file_format parameter of standby database ? On
primary db I have defined "infod LOG_ARCHIVE_FORMAT=infod_log%s_%t.arc. Do I have to keep same or change it ? If on standby db I change the value do I
require other parameters to be set ?
regards & thanks
pjp

Q/A1) Its correct you dont need the standby keyword. Not sure abut the reason why but we have created logical standby running in prod using the oracle doc.
Q/A2) Yo can specify any location and name for your controlfiles as it is instance specific and not depending on primary database.
Q/A3) You can set any format for your archlogs on standby side. It doesnt bother the primary db or DG configuration.

Logical host name Question

Hi
Iam in process of creating 2 node cluster on 2 domains.This is for FailOver Clustering
I would appreciate if someone can throw some light and explain if Iam doing right and answer some of the Questions that I had
We have created 2 RG and we are in the process of creating logical host name. Here are the steps that I think Iam going to execute
1> The name of the logicalhost name resources are LH-01 , LH-02
The name of the logical host name are virtualhost-01 , virtualhost-02
The name of the domains are domainapp-01 , domainapp-02
2> Create entry in /etc/hosts for the new logical host name and IP address
Question : Is there any command which can be used to add entries to this files , instead of manually addding them. Iam not a Sys Admin and I do not know how many more places I have to add.
3>Create logicalhostname resources by following commands
a>clreslogicalhostname create -g RG-01 -h virtualhost-01 LH-01
b>clreslogicalhostname create -g RG-02 -h virtualhost-02 LH-02
4>Edit the /etc/nsswitch.conf
Question : I could not understand why we have to do this and what needs to be modified. Do I have to comment out the lines which says
host: cluster files
rpc : files
5>Question : Do I need to also create Shared Address Resource? I really did not understand the concept of Shared Address Resource
I would really appreciate if someone can throw some light on this. I have gone through the documents , but It really did not clear up for me
Thanks
Edited by: Cluster_newbie on Jun 25, 2008 4:06 PM

actually scinstall put this host: cluster files , i dont remember was the the logic
here is some explaination about shared address which used scalable applications like apache
The SUNW.SharedAddress Resource Type
Resources of type SUNW.SharedAddress represent a special type of IP
address that is required by scalable services. This IP address is configured
on the public net of only one node with failover capability, but provides a
load-balanced IP address that supports scalable applications that run on
multiple nodes simultaneously. This subject is described in greater detail
I hope this helps

I think we can create a fast refreshable Mat view which has UNION ALL operator... I don't know about remote tables.
How to achieve this... with out splitting the Mat view ?. Is there any way..?
Appreciate your help.
Thanks,

Replace the ANSI Joins with Conventional Joins.
Change this :
SELECT * FROM V_FIRST VF
LEFT JOIN R4
ON VF.ID=R4.ID
LEFT JOIN R5
ON VF.ID=R5.IDto this :
SELECT VF.* FROM V_FIRST VF, R4, R5

Oracle 10g - Introduction to SQL course question

Two years ago I completed the Oracle 9i - Introduction to SQL course. An complete the #1Z0-007 exam and pass with almost 100%.
I notice that Oracle 10g - Introduction to SQL courses are now being offer. If I have already done the Oracle 9i course and have been using SQL for the pass two years. Is doing the Oracle 10g - Introduction to SQL worthwhile ?
Will I learn anything new or is the course almost the same ?
Thanks
Brendon

Brendon,
Almost certainly not useful. I'd compare the contents of the course you did with the features that have been introduced into Oracle since the version that the course was based on, and try to find some material on these features.
Cheerio,

IMac 20" refresh rates question

How do I find out what refresh rates are supported on my iMac 20" Core Duo? I don't see anything in system profiler and or the display preferences.

Also, are there any versions of ATI Catalyst drivers made for the Radeon X1600's that come in these?

Logical standby database questions

Hi,
1.Is it possible to encrypt just the logicals standby database? ie primary is not encrypted but when the data comes to logical standby it gets encrypted?
2. Is it possible to replicate only certain schemas to logcial standby?
Please let me know,
Thanks a lot
Sumathy

Hi Sumathy,
1.) Yes this is possible
2.) Yes also possible. However Logical Standby will always gather all information from the primary, and only skip in the apply process.
If you want to lessen your transfer, then you should use other replication mechanism like
- Golden Gate (preferred but does cost money)
- Streams (free, but depricated)

Refresh Portlet question

Hello,

I have two portlets that are in the same page. One portlet is a data submitting portlet that lets user submit data, and the other one is a data presentation page that display all the data that user submitted. When users click on the button to submit data, the page will be refreshed and the new data will be displayed in the second portlet.

I use adaptive portlet to do auto refresh. It works fine for a long time. However, it suddenly turns error to me. An IE window pops up every time when I submit data. The error message in the popup window is:

A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive.
 Do you want to abort the script?

If I select "Yes", the page won't be refreshed. If I select "No", the page will be frozen. However, the data has been saved in database.

Does anyone has the same experience or know this issue? How can I fix it?

Thanks in advance!

Hi,
If you are developing in .NET then it should be pretty easy to achieve individual portlet refreshes. If you want to search on the portal for these types of portlets we have called them 'adaptive portlets' (I have no idea why...).
What you need to do it first install our .NET Web Controls support, which you can get from here: http://portal.plumtree.com/portal/server.pt?open=512&objID=3422&PageID=5590&cached=true&mode=2&
Follow the included guide - basically you just need to add a few lines to you web.config then your ASP.NET webapps/portlets will refresh (postback) in-page without refreshing the page.
Hope this gets you started!

Early 2011 MacBook Pro logic board upgrade question

I have an early 2011 MacBook Pro 17'. Will a late 2011 logic board fit in the unibody of an early 2011? My logic board crashed and I'm looking to install a new one myself. I just need to see if I can upgrade mine at all. I want to purchase a logic board with a faster processor and hopefully not as prone to the GPU failure. Any recommendations?

You have the problem discussed in a number of discussions on this forum, most notably here -> https://discussions.apple.com/thread/4766577?tstart=0.
Basically the GPU in the machine was poorly soldered onto the logic board. If you take the machine into an Apple Store, they will recommend a logic board replacement. This, however, will not permanently fix the problem. The only permanent fix is to have the GPU 'reballed' - this will cost about $160 and some services offer up to a year's warranty on their work.
I had the problem back in January and, as I was under AppleCare, had my logic board replaced gratis. Once I'm left with no warranty, I will have the GPU reballed.
Take a look at some of the discussion and see some of the photos which are just like yours. The only remedy is the reball.
Good luck,
Clinton

Macbook and Logic Pro Quick question

im sorry guys i know there is alot of topics on this but im crunched for time and i need to get a computer as soon as possible. I found a macbook with 2.0 ghz, 80 gb 5400 harddrive, im going to get 4 gigs of ram, 667 mhz system bus. (im probally going to get an external harddrive)
potentially i can get a better one with 2.2 ghz
Which would be better? Is the first one enough?
I use logic to its breaking point with 40-60 tracks almost all have reverb and other effects (i make ambient music)
thanks

If your doing that many tracks with effects, go for the fastest cpu and the most ram you can get. Otherwise you going wind up freezing tracks a lot. You will also need a large firewire external drive running at 7200. If you don't need to move around an iMac is more bang for the buck. If you do and you have the money check out the new Macbook Pro. They're much faster, have a 17" screen option and can be purchased with a 200 gb 7200 internal HD.

New to mac/logic - set up question

Getting ready to install Logic on new iMac, I've been told to wait to install until I have my interface (MBox Pro) - and it's on order. I'm trying to determine what I may need to do as far as prepping for it. I've been reading about turning "disk journaling" off when recording. I found that in the disk utility, but it is grayed out. Do I need to reformat my drive or something?
My initial idea was to record internally, and back up to an ext. drive, but after poking around these forums I am considering getting an ext. drive to record to. So am I correct that if I run a firewire 800 drive next to the computer, and daisy chain the Mbox to that (which runs at FW 400), I won't have performance issues? Or should I consider a FW hub (which for FW800 are few)? Looking at a Glyph 7200RPM drive for this.
Any other "first timer" tips or links appreciated.
Thanks.

No reason to wait for the interface - you can use the built in audio of the Mac until then.

It is greyed out when you select the DRIVE in disk utility. Note that on this disk journaling is disabled already.
When you select the Volume (=the 'desktop-name' of your disk) it should be available.

Good plan!

Mbox is Digidesign, right? In that case I will not guarantee anything - but yes, it should all work well nevertheless.
Or should I consider a FW hub (which for FW800 are few)? Looking at a Glyph 7200RPM drive for this.
Don't use a hub. I believe that FW is all on one bus, so even if you have two ports all will adapt to the slowest thing attached. I don't think a hub will change that.
Any other "first timer" tips or links appreciated.
