On which drive should I put samples? Is EXS, Ultrabeat, etc. streamed/ram?

Hey, i am setting up the new iteration of my home studio. I upgraded to 7 Pro recently and am taking advantage of the new 500GB internal hard drive. My question is, should I relocate (via alias) my EXS24 and Ultrabeat samples to my new 500GB along with BFD?
I ask this because I am not sure if those Logic instruments stream the audio from your HD or if they are loaded into RAM.
If they are indeed streamed I will plop them with my BFD and leave my native OS drive to just app running and as scratch recording (later putting the audio recordings on the secondary 500GB drive). Any advice? Thanks!

Greetings, Scroto.
This is not a straighforward answer...
EXS24 does its best to move what it needs into RAM. For instance, check out Options > Preferences on the EXS24 panel. You can even get the EXS24 to keep common samples in memory when switching songs.
However, I prefer to have anything that might make the drive work hard on my system disk. So, samples and video are normally on my system disk so that Logic can stream quite happily to my scratch disk. Having said that, I've sometimes had jerky video (Logic gives priority to audio) so moving that file to the scratch disk has given me silky smooth playback.
So, for my working rpactice at least, there are benefits in both methods. I have worked with people who put all AV material, including samples, projects (therefore including freeze files) and anything else on their scratch drives and then wonder why they get mixed results, including the dreaded out of sync message.
I only have two high-performance drives but can see the real benefit of having a third FW drive which can then hold all samples, video material and so on, leaving the scratch disk for audio alone. I'd appreciate comments from anybody who has tried this.

Hi,
which ORACLE_HOME should I put in .profile to export?The Linux .profile is for setting-up your Linux environment, and it gors into Linux directories. The OS .profile can be global (/etc/profile) or local (as specified in each users /etc/passwd) for each OS user. I have notes here:

Thanks in advance!
Since it was a new iMac he was going to purchase, there is the huge iMac/Fusion Drive Thread.
The other thing is... the Fusion drives offer no improvement over standard drives for audio, in fact performance may be less, plus there is an additional software layer installed to mange the Fusion Drive... and to top it off, the the regular spinning disk of the Fusion Drive is only 5400RPM.
Here's the thread.

HELP - which driver should I use?

Hi,
          We are developing an application using WebLogic 6.0 in conjunction with
          TOPLink 2.5.1 for object/relational mapping (manages the persistence
          layer). We would like to configure our application to use WebLogic's
          connection pools and I would have a few questions regarding the driver I
          should use.
          Here's a short description of our application:
          Our service layer is entirely composed of container managed stateless
          session beans. On the TOPLink side, the transactions are manipulated by
          a UnitOfWork object, which gives the control over the distributed
          transaction to an external transaction controller. Our WebLogic external
          transaction controller uses the UserTransaction interface to manipulate
          a transaction (begin/commit/rollback). So, within an EJB method
          execution we might have several units of work begin and 'commit'
          transactions, but the overall transaction is really committed only at
          the method exit, by the external transaction controller.
          This works, without using connection pools. The problem is, if we don't
          use connection pools for every SQL executed, a new connection is created
          and authenticated against the Oracle Server, which is terrible for
          performance. However, when I tried to configure a WebLogic connection
          pool, it doesn't work anymore (by using the non-XA OCI driver the
          connections from the pool were used, but never released back to the pool
          after the transaction was being committed).
          My questions are:
          1. Given that our transactions are manipulated through JETS, is it
          correct to use the JTS Oracle driver, which comes with the WL6.0
          installation?
          Driver Classname: weblogic.jdbc.jts.Driver
          URL: jdbc:weblogic:jts:myOracleInstance
          2. If we should use the JTS Oracle driver, should I specify the pool
          name in the Oracle URL?
          3. What is the difference between jdbc20 and jdbc? Is the first one
          deprecated?
          Thank you,
          Brenda.

Hi Sriram,
          Thank you very much for your help.
          I used the datasource configuration as you suggested and it almost
          works. It is noticeable faster than before,
          but the problem now is that I am getting the following exception when
          loading the sixth object into the database.
          I do not understand why it is the sixth object, because I created the
          Oracle connection pool with a maximum of
          10 connections.
          Here's the exception I get:

Which driver should I use for Oracle RAC .....

We are using Weblogic 8.1 sp2 and Oracle RAC (9.x). Which driver , I should
use : i.e.
type 2 Orcle thin driver
or
type 2 Oracle OCI driver
or
type 4 oracle thin driver
or
Jdrivers
or other which is best for this configuration .

How come you choose the thin driver? Oracle will generally
fix the OCI driver before the thin and the OCI driver will
give far superior performance when dealing with LOBs.We have actually had faster response getting thin driver fixes
than OCI-based fixes. Thats interesting. I'll take note of it.
The 10g driver works with RAC, is much faster than previous
drivers, and is easier to install etc. OCI users are often
hopeful about TAF, which is broken and less-than-useless for
active complicated JDBC applications. OCI problems can bring
down the whole JVM and are harder to debug.
These are from reading the results and recommendations of
Oracle Corporation, Tom Kyte and other Oracle professionals.
Have you research to say different? I'd like to see it,
because up until now, I've always suggested OCI first unless
the client doesn't have an oracle client installation
available.Tom does an excellent job from the DBMS perspective, but I
don't see him often in the jdbc arena.His Q&A site is littered with jdbc examples. He also will call
on people in specific expertise to help him answer questions.
Here an example of that where he show the OCI driver to be much
more performant.

I have a problem regarding partitioning my hard drive. Which drive should I change into logical?

My 500 gb harddrive of Hp Pavilion G6 notebook has 4 primary partitions already. First - system (199 MB), Second - C: (450 gb), Third D: Recovery (14.97 gb) and Fourth Hp_tools (103.02 mb). I want to divide my C: drive into 3 partitions 150 gb each. I'm using MiniTool Partition Wizard software. It doesn't allow me to create further partitions because I have already four primary partitions. So, I have to change one to logical partition. Which one should I change?

Which drive should I buy for iMovie? I only have 1 FW 400 and 1 USB2 port.

I have a 12" 1ghz AiBook and am getting into some iMovie editing, but I need a new hard drive for extra storage, and I need help figuring out what'll work.
Despite having maxed out the drive config (it's a 80 GB 4200 RPM drive, with about 11 GB of free space) there isn't enough to hold a full MiniDV tape's worth of clips, let alone to edit together a decent little project.
So I'm left with the following options:
* Upgrade the internal drive
* Buy an external FW drive
* Buy an external USB2 drive
The first option is obviously ideal, performance-wise, since I can get a speedy 7200 RPM ATA drive, but it's also very expensive, ~$150 for a decent drive, and my battery life will go to heck (moreso), and the install on the 12" is a PITA. So I'd like to avoid that.
For an external drive, I already have a USB2/FW enclosure with an old HD in it, so I'm considering putting a 7200 RPM drive in there and see if that'll work.
So my question is: Will it? Can I capture video to the drive in either USB2 or FW mode? Keep in mind that if I use it as FW, I'll have it on the same bus as the camera, so it'll be splitting bandwidth (or something). USB2 of course has its own problems...
What's the best way to go here? Should I just suck it up and upgrade the internal drive, or is a decent USB2 drive sufficient for capturing DV (not high-def) from iMovie? (After capture, I could always re-connect the drive via FW to keep throughput higher for DVD burning.)
Just looking for advice before I plunk down my hard earned cash.
Thanks in advance!

I've never had any dropouts running any Sony camcorder "daisy-chained" through an external FireWire drive as long as the external drive has a 5400rpm or faster disc in it.
That's been true for G3 and G4 laptops, a Mac mini ..well; for all the Macs listed below (in small print).
But be aware - as Karsten says - that many Canon camcorders just won't do that: they won't work properly if any other FireWire device is connected to your Mac besides the camcorder ..so they will not work "daisy-chained" through an external disc ..see Karsten's suggestion about importing to the internal disc, then moving all that video to the external disc for editing. However, if you have next to no space on your internal disc, you'll need some other strategy, or to simply MAKE some space there.
I've upgraded alumin(i)um PowerBooks (12" and 17") to 120GB fast internal discs, and that doesn't seem to have diminished their running-time on battery power. But it's a finicky job with a 12" PB ..especially getting the F1 keytop to re-seat properly afterwards!
So if you don't have a Canon camcorder, it's probably best to get a fast external FireWire drive and capture and edit on that. If you DO have a Canon camcorder, it may be better to upgrade your internal disc, but you'll need concentration, steady hands, patience, and persistence (..trying to get that F1 keytop back on again!)

Which slot should I put in PCI card in?

Finally going to migrate from my older Mac to my new Intel Mac. I'm in the process of putting my fiber channel card into my new machine so I can connect it to my Xserve Raid. As I was about to put the card in the new machine on slot #2, I noticed that slot #4 said "X4/RAID" on it. Now I'm wondering which slot I should put the card in. Does it matter? I can't find anything other then slot #1-2 are X16 and slots #3-4 are X4.
Help.

Hi
The slot you're looking at is specifically for Apple's RAID Card. In other words if you have the Card it probably won't work in any other slot than the one marked specifically for it. More information here:
http://support.apple.com/kb/HT3514
http://support.apple.com/kb/HT1346
http://support.apple.com/kb/HT2838
You should be OK using the slot but if it bothers you any other slot will do.

Which drive should be the master?

HI all
I have a Power Mac G4 AGP, originally with 350mhz, but i upgraded the processor card to 1.2 Ghz. and I also have 1.31Gb of RAM. I need to upgrade the Hard Drive storage now I have a 40gig and an 80gig. i just purchased a Western Digital 250GB and a ACARD AEC-6280M PCI IDE Controller Card. My question is should i have the master drive on the 250gig drive or the 80gig or the 40 gig drive, does it matter how big the drive is, currently it is on the 40 gig drive. So the 40 and 80 that are currently on the G4 are UATA? and the new 250 gig is being accessed by the pci ata card, is there a difference? would the 250gig drive be faster?
sorry there a couple of questions here.
thanks so much

Hi, zinger123!
Regarding partitioning... consider the drives/volumes that you have, what you're using each of them for, and how you intend to backup/protect the data on each of them in case of a drive failure on any one of them. If partitioning will help to assure the safety of your data by configuring additional partitions/volumes to accomplish this, then go for it. If you already have a backup strategy in place that covers what's important to you on the three drives, and you decide that perhaps a spare volume is unnecessary, then run the drive as a single volume to get the most out of it.
If you do partition, the most common mistakes are to create too many partitions, and/or to create partitions which are too small to be effectively used, both of which waste drive space.
For example, if you now have, say, 30GB on your startup drive, and create a partition of 40 GB on a new drive to use as your new startup drive, you'll have a volume with 30GB of data and 25% free space for the OS to operate with. A year from now, the 30GB might be 35GB and the free space will decrease to 12.5%. At that point, you'll be concerned about a volume that's getting full again and perhaps wondering why you can't burn an iDVD project... Keep in mind that once you partition and load data onto one or more of the partitioned volumes, you must move the data from those volumes to repartition the drive, since safe repartitioning requires that the entire drive be erased in the process, or that a backup be done if a software-based, on-the-fly repartition is done. Thus, it's better to err on the "too-large" side than the "too-small" side...
For whatever it's worth, I selectively use partitioning when it suits my needs. I also have spare volumes/drives available for flexibility in moving large amounts of data or entire systems from one volume or drive to another. My six year old daughter and her friends can play all they want on my Macs and I don't have to worry about them deleting the System Folder or trashing my iTunes... The point is, you might give this some thought to make best use of your newly-acquired space and provide for backup.

Which driver should I use

I am considering to use a native JDBC driver instead of the JDBC-ODBC bridge. The reason for that is that I need an improvement in performance on select statements. Deletes, inserts and updates are not important.
Does anybody know what kind of improvement in performance I could expect when using a native JDBC driver? I'm using both Oracle 8i and MS SQL Server 2000 as databases, but I'm most interested in the performance improvement for SQL Server.
Has anybody tried for instance Microsoft's "own" JDBC driver?

MSs Jdbc Driver still requires Jdbc-Odbc bridge.
Just go thru the URL,
http://www.weblogic.com/docs/techsupport/faq/jdbckona_m
sqlserver.html#bridge
Hope this helps.
SudhaThanks for the URL, but I think this page does not refer to the beta-JDBC driver which MS has made available recently. For instance it says that Microsoft's driver is a type 2 driver, while in reality it is type 4.

Which drive should I get?

I discovered this morning that my iMac internal CD drive (superdrive) is broken. The computer does not see it and it won't take CD's and I can only assume that it has finally died.
Can anyone recommend a new internal CD drive (burning also) that I can install myself for my iMac G5 (10.4.11)
Thanks,
Julian

I have a MBP (first gen. unibody) that has a 320Gb drive as well. For primary backup, I have an OWC Mercury Elite-AL Pro firewire 800 1TB drive that works really well. It is actually partitioned with a ~320GB partition for a full bootable clone (which I update weekly or so) and then the rest for TM. With TM, I can go back several months for most things (much more for things that don't change often), and with the clone, I have a bootable clone right there if I ever need to boot to my desktop and all my stuff from an external source. The drive is about $180, but well worth it - firewire 800 (and it has 32MB cache) is noticeably faster then my older backup drive (a WD MyBook 1TB USB2 drive, which is now just general storage).
Just my opinion on one way to go.

When installing Firefox 35 into Windows 7 running inside VMware Fusion on a Mac, into which folder should I put the downloaded Firefox installer file?

Inside Windows I see a folder called PROGRAM FILES and another one called PROGRAM FILES (X86). Is either of these the correct one to put the Firefox installer program into before I launch the installer? There is also a folder called WINDOWS. Sorry for such an elementary question but I've never been a Windows user; just Macs so far until now. My intention is to download the Windows version of Firefox using a browser on the Mac side of the computer since I have working browsers there. Then I would copy the ".exe" file to whichever Windows folder is correct. Am I on the right track or am I courting disaster?
Also, will there be a preference inside Firefox to make it the default browser in the Windows environment? I'd like to avoid using Internet Explorer.
( I'm writing this from the Firefox browser, v. 28.0 in the Mac OS (10.6.8). I didn't click the "Automatically Add" button for submitting troubleshooting information because I'm not asking about the browser in the Mac OS environment.)
Thank you.

The full Windows install file from for instance https://www.mozilla.org/firefox/all/ is an executable dot.exe file.
It will run from anywhere the user has the correct permissions, incluing the desktop or the downloads folder. It will offer standard or custom installs, usually opt for the standard install and the necessary flies and folders will be created.

Setting Firefox as the default browser may be done from an option as Firefox starts after installation

In Which Directory Should I Put the Configuration File?

I am using Servlets and JSPs. I have code like:
private static final String OPTION_FILE_NAME = "mvnplugin_mvnforum_MVNForumConfig";
    static
       ResourceBundle res = ResourceBundle.getBundle(OPTION_FILE_NAME);
       MVNFORUM_HOME       = res.getString("MVNFORUM_HOME").trim();
       WEBMASTER_EMAIL     = res.getString("WEBMASTER_EMAIL").trim();
       LOGO_URL            = res.getString("LOGO_URL").trim();
       String supportedLocales = res.getString("SUPPORTED_LOCALES").trim();
       SUPPORTED_LOCALE_NAMES = StringUtil.getStringArray(supportedLocales, ";");
    }And "mvnplugin_mvnforum_MVNForumConfig.properties" is a configuration file. Please advise regarding the directory in which this properties file is supposed to be for my code to read it properly.

Somewhere in your classpath, typically /WEB-INF/classes.

Which category should I put my podcast in?

Yeah, that's probably where it will end up. Although that section seems to be more about "How to" podcasting. My podcast just reviews other podcasts. See my dilemma?

On which drive should I put samples? Is EXS, Ultrabeat, etc. streamed/ram?
