Who will be the best option with Oracle 11 g dd loadbalancing and failover

We use weblogic 10.3 with multipool with each source of data pointing to each RAC node. The Multipool manage failover and load balancing scenario. With 11g database now, we have the ability to use SCAN where weblogic will point to a service and load balancing/failover happen side DB.

Published by: user1122 on April 12, 2010 10:47

Stick with MultiPools for now. SCAN will confuse pools WLS and will harm XA if you
using XA, because WLS assumes that all connections in a pool are identical. If some are
bad, WLS assumes that all are and can kill all the. We try to ensure that all the work
in a given transaction goes to a specific node of the RAC, but if the pool is heterogeneous
We can spoil, and depending on the version of the DBMS, it will suffer performance
questions to the best and can corrupt and if it gets worse...

  • What are the best options for the composition of math in InDesign CS4?

    What are the best options for the composition of math in InDesign CS4?

    I tried a few versions of the composition of mathematics test. All have their advantages and disadvantages, but I can't decide on which the plugin/script will be the best in the long run (in taking account of the ePub and MathML).


    So far the two best seems to be InMath (if it becomes compatible CS4) or Math + Magic Pro.


    The biggest pro of InMath is editable on the screen, but it seems to have some risk: http://InDesignSecrets.com/InMath-update-with-new-reader-functionality.php


    Math + Magic Pro works well with CS4, but need of equations to modify in the window of their plugin, and because they are EPS format. The file size and the ability to work with a digital player disappeared.

    And MathType seems pretty useless...

    Someone at - it had positive experiences?

    Not exactly the kerning, but you can move blocks wherever you want with the arrow keys. And you can change the spacing between the elements by changing the spacer between them. There are also defects of spacing.

    Batch edit can be something again. I use 6.0, and I see that the most recent version is 6.5.

    I had problems with files EPS of Mathtype, which may include a preview, but do not include fonts. So, I opened each equation of the word with my default settings (they automatically change the default fonts, spacing, size, etc.), copy, paste in Illustrator and save as have. So when I'm finished, my equations are always vector (if that's what you mean by text).

    Microsoft has chosen to implement a version of Mathtype dumbed-down as the editor of Word equations for many years. So for me at least, long term has already been decided. There are several things wrong with Mathtype, but given the choice between the use of Mathtype to * convert * equations and using InMath or mathemagiques to * recreate * equations, I'll take Mathtype, warts and all.

  • Is EXFAT the best option for me

    Hi, I bought a new WD 2 TB HDD to use to copy my edited video files on FCP and many other forms of data from my Mac on this disc. I want to use with Time Machine at the same time. I also want to be able to use it with Windows to read & write on both the Windows operating system and Mac OS anytime. EXFAT is the best option for me or are there restrictions?

    Thank you.

    Yyes, if you want to use with Windows. Use a separate drive for Time Machine. Whose combined libraries of the PCF and Time Machine on the same drive.

  • What is the best option of BD - R at price

    I just upgraded from DV to HDV and get used to a new camcorder AG-AC160A and first Pro CS5. The learning curve becomes more costly than expected and the price of BD - R discs. Any thoughts on what the best option is for less expensive, but reliable discs Blu - Ray discs for the practice? I used Verbatim 25 GB 6 x. I thought I read somewhere that I should not use rewritable discs for video. Thank you.

    I use optical quantum BD-REs for the test.  They seem to work pretty well with my Sony.

    But for the customer, I recommend that you use only Falcon Pro.  They are more expensive, but happy customers are well worth it.

  • How can I make the best use of a new external hard drive and a new catalog full of photos just loaded into Photoshop elements 14 Organizer?

    How can I make the best use of a new external hard drive and a new catalog full of photos just loaded into Photoshop elements 14 Organizer?

    Keep all the files on external hard drive image?  Nothing else and no pictures on the desktop?

    Keep all image files both places?

    What is the best way to go through thousands of images in the Organizer to identify and place them in files?

    Once I've placed a file, I just leave it in the entire catalog or a way indicate to me that it has been sorted?

    As overwhelming, any tips/shortcuts/schemes, you can offer are welcome!

    As I only have the version of the EP, here is some info on the organiser:

    https://helpx.Adobe.com/Photoshop-elements/how-to/use-elements-Organizer.html

    Independent of how this feature works, you want to have your photos in one place and have a backup (second copy) somewhere else. All hard drives will not be successful at some point - some more early, some late - never trust to have your files in any safety devices if they are on a single disc. Once you have your sorted, it would be useful that you will organize/name/tag new photos immediately if the task is relatively short and simple. I copy my photos on my internal hard drive for my camera, take a quick look with preview to see who needs some changes and then decide where to put them - either drop them immediately after naming them or bring in an editing application and then file them away.

  • What is the best option for merge prel seven projects - using an intermediate file. using Premiere Pro or a Clipboard Extender?

    I did no editing for a few years and suddenly received (for me), a difficult task. I have now just finished editing a wedding shot with 4 video cameras (I took a few videos and other formats have been those who shot at random), in the first 14 elements. The formats of the clips are also different. Due to the fact that there was overlap so many scenes and the complexity of the task, I have divided marriage in 7 scenes, each is a file/project prel e.g. married dress, ceremony, etc. I didn't know at that time that it might be difficult to merge the projects. The final step is to merge these files so that I can make both BD and DVD.

    I initially purchased Premiere Pro for editing, using Pinnacle for years, but I was struggling too much with the Pro and the different formats of the clips, add music, overlapping, etc. Then I bought elements and was very uncomfortable with the Expert mode. I think that I am now ready to start using Pro.

    The specs of my computer are:

    OS: Windows Pro 64-bit 10. current version: 10.0.10586.306

    gigahertz Intel Core i5-2400 3,10; RAM: 8, 00 GB Dual-Channel DDR3. 64 bit

    First Elements 14.0.64 Version
    First Pro CC 2015 Version 9.0.0

    Here are a few clips (from MediaInfo) specifications (some of them might have been converted as they were given only to me some time after the wedding):

    1. Codec: AVC; Variable bit rate; Bit rate 16.4 Mbps; 1920 x 1080i. Frame rate: 25 fps; Sound: AC - 3; Bitrate: 256 Kbps
    2. Codec: H.263; Constant bit rate; Bit rate 36.6 Mbps; 1920 x 1080; Frame rate: 25 fps; Sound: AAC; Flow rate: 192 Kbps
    3. Codec: AVC; Variable bit rate; Bit rate: 24 Mbps; 1920 x 1080i. Frame rate: 25 fps; Sound: AAC; Bitrate 96 Kbps
    4. Codec: MPEG video;? Variable or Constant; Bit rate 25 Mbps; 1440 x 1080i. Frame rate: 25 fps

    Sound: MPEG Audio AC-3; Bit rate: 384 Kbps

    I tried to read as many threads as possible in this regard, but couldn't find much on the internet and most son/tutorials are quite old and refer to previous versions of Premiere Elements. I tried to merge it with Premiere Pro, after reading this (https://helpx.adobe.com/premiere-pro/using/importing-sequences-clip-lists-libraries.html; ( http://www.mediacollege.com/adobe/premiere/pro/import/), but I've struggled, as in the two references, it was either too little info or the guideline was not clear to me.

    I also saw wires on clipboard Extender (ClipMate and Spartan Lite) https://forums.adobe.com/thread/1148100 I downloaded Spartan Lite, but that seemed pretty confusing.

    I'm very uncomfortable to use intermediate files (https://forums.adobe.com/thread/875797?tstart=0) that I have enough space on my drive hard, but made a loose quality? On the other hand, I suppose it might be good for me to start using Premiere Pro now.

    What is the current consensus?

    Then I have another question and I don't know if I need to open a new thread for this. As I have shown above, the clips have all different characteristics and some files prel are save as 1440 x 1080 (where the scene starts with a clip of nr 4, others like 1920 x 1080) I guess I should have converted clips all to the same specification before editing, but I did not. There was so much work involved in this process that I can't think to change to a format and replace them current clips, etc. With the rendering, the different specifications will be a problem?

    One last question - I guess I just need to go to the BD and DVD specifications, or should I also realize the whole project in a format without loss of keep for possible future use?

    Another option is to use Cineform, who is a Visual lossless codec and produces smaller files means then Lagarith.

    Download Gopro Studio and install.

    This will give you the codec.

  • Setup error ODAC 12 c R4 client on the same machine with Oracle 11 g 64 bit for Windows database

    I have Oracle objects and mobile application development with:

    Windows 7 64-bit OS

    Base Oracle = C:\ORA

    Database Oracle 11 g 64-bit 201, home = C:\ORA\DB11G201

    I was running in Visual Studio 2010 and the ODAC customer Oracle 32-bit in another home = C:\ORA\DB11G201CLIENT32

    All was well for a few years on that set up.

    I decided to upgrade to Visual Studio 2013 and .NET 4.5

    Deletion of Visual Studio 2010 and installed Visual Studio 2013.

    I did a normal uninstall of the Oracle 11 g 32-bit client using the rebooted, Oracle Universal Installer.

    The customer old house was gone.

    I downloaded the ODP.NET12C 32-bit Oracle with VS tools R4 and began the installation of the client.

    I selected English and built-in OS account

    I chose Oracle base = C:\ORA

    I chose hone Oracle = C:\ORA\DB12CR4CIENT32

    But I encounter the error:

    [INS-32104] User Oracle Home specified is not the owner of the Oracle Base specified.

    The owner of C:\ORA's ADMINISTRATORS.

    When should I do?

    For guests of 12 c, opened a NEW BASE and a NEW HOUSE?

    Created an ACCOUNT to STANDARD USER and the select statement, but keep c:\ORA and the new C:\ORA\DB12CR4CIENT32 of the House?

    I'm a hold out for migration to Oracle 12 c database because they thrown into the very useful tool Oracle Database Control and replaced by something watered down.

    So I like to keep the Oracle 11 g 64-bit database.

    but Visual Studio 2013 support, use the 12 c R4 32-bit and 64-bit support drivers unmanaged.

    I would use (and use) Managed drivers, but they do not work in database 11g FIPS-140 active environments.

    Thank you for your help and comments.

    Hello

    This is expected because you install 12 c in Base Oracle who has home 11g.

    From 12 c, the installation program has promoted "Oracle Home User' where you can perform the installation with built-in admin user or a secure non-admin user.

    As documented at https://docs.oracle.com/database/121/NTCLI/install.htm#NTCLI1283

    "Oracle 12 c Release 1 (12,1) database client may not share basic Oracle with houses of the Oracle database versions, such as Oracle Database 11 g Release 2 (11.2) and sooner."

    Please see the information listed in the link above for more information.

    Bascially, you need to install in a different Oracle Base and can have all this work.

    Kind regards.
