Need information about dataguard / stream for our scenerio!

Hello

We have an application with Oracle 11 g (he calls as box 1), the day-to-day operations of form currently apart load that we have, there are two or three other apps also considered tapping/approach of our primary database (box 1) that puts a lot of load on the Pb and the server. I've done a few go - ogle and found that data guard or water courses can come handy also to lower the load through box 2 dB pending... So I think I have a standby server either box 2 that will meet all reporting requirements and primary will just play a role of data entry & req little statement.

So my question to you guys is:

(1) assuming I want to just unload some server load in box 2 in effect considered, is an option to fetch DataGuard. If Yes, then what I have to go with physical or logical standby standby assuming that our database awaiting will be just right for having reported the end or in other words all the reports of applications such as data warehouse wil approaching standby db?

2) given that I understood the watercourse is very convenient if I want to have more control over what is shipped in box 2 as an update, as you much finer granule setting i.e. level table, etc. level collar. Since we have always have full db in sync, stream be not useful in our case, the right?

Hello

Here, two things are different) 1 standby) 2 flow, obviously related to replication

From 11 g, you can use physical standby for payment purposes, this means select statements will work i.e. you can say read-only data recovery also will be activated too.

In this process, users who perform operations only in read-only , no operation of inserts/updates / removal is permitted.

In streams, it works on heterogeneous platforms, you can perform the data replication, which can be also some objects or diagram, complete database. There will be a lot of addiction too.

To SYNCHRONIZE the two databases that you can fetch the data keep that only comes with the cost of the Enterprise edition. Mode standby is exactly the mirror copy.

  • Need information about the data included in the example for the inner race with flaws

    Hello

    There are several examples for fault detection in bearing (Vibration tool sets). I need more information about these data include:

    -Bringing its specifications

    -How to perform data acquisition

    -a link to the tutorial

    I came across this manual that shows how to use OATS envelope detection VI to perform detection of failures of bearings.

    http://zone.NI.com/reference/en-XX/help/372416A-01/svtconcepts/cst_speed_brg/

    It lists the specifications of turnover:

    • Inch diameter 0,2813

    • Primitive diameter: 1,1228 inch

    • Speed: 1 234 RPM

    It also goes to the list of characteristic frequencies determined by these attributes.

    The data acquisition is carried out by the use of an accelerometer and a tachometer. These devices measure the vibration and the rotation speed of the bearing data. Failure detection uses a method called detection of the envelope to look at the signals of the bearing and compared to signals of standard bearings to the discovery of flaws. You can learn more about the method of acquisition of data here:

    http://zone.NI.com/reference/en-XX/help/372416A-01/svtconcepts/fault_detection/#Envelope_Detection

    The first link is a tutorial on the detection of failures in the bearings. The end of the link provides the location of an example VI that may also be useful.

  • Need information about Satellite L30-134

    Hey, I know this off another machine brand new Tablet and all, but hey, I can't find a single web page with information on this machine other than what is in the manual sold with the laptop.

    I like a seasoned PC enthusiast I had a lot of questions about this machine also, (I'm already impressed with its capabilities for the price you get really shot for your bucks...) I would like to know the socket U23 does not say my much.

    Can I upgrade the processor? The BIOS is also very limited. Y at - it an upgrade? I would like to know if I can disable smart perform duel memory modules or change the amount of memory dedicated to graphics? I was seriously thinking of launching a forum of my own to find out these mysteries, after all it is a popular purchase, I saw two other people, the purchase of this machine on the same day as me...

    I need input, anyone can meet my desire for more information?

    Hello Tom

    Weather, you are passionate about PC, but I fear that you will be a little disappointed because with laptops you can not do much. I hope you know a lot about desktop computers and upgrade opportunities. The situation with laptops is completely different. Upgrade opportunities are minimal and there is not much to do.

    When you buy from office, you will get a user manuals of motherboard with all the information about it. Computer laptop manufacturer doesn t give something like that because there is no possibility of upgrade for processor and graphics card. The construction of the laptop is very complicated and many powerful hardware components are placed on the very small box. A common problem with laptops is cooling and how to remove the heat.

    Laptop manufacturer has two priorities: build the right machine and also build with unassailable cooling system to protect the material and portable secure long life. There are many things that must work harmonic.

    You can upgrade RAM to HARD drive, but not anymore. Using different settings, you can try to improve your laptop for use. All that s!

  • Need information about the licenses on DB and EBS

    Hi all

    Nice day!

    I have a few questions regarding licenses in Oracle. And will appreciate the supporting by the Oracle Doc for reference.

    My DB version is 11.2.0.3 and the Oracle eBusiness Suite version 12.1.3.

    1. we bought 100 NUP for DB. However, when I checked with the following query:

    Select * from dba_users where account_status = 'OPEN '.

    The list of users exceed 236 (Note its an ERP instance), where the number of users we have created by me is just 4-5. Others came to OPEN by default (including system, dbsnmp, sysman etc.).  They should be counted in the licenses that they are installed before users?

    2. I have observed that some users dba open are for modules that we do not use. Can they be locked safely? [For example.] IPD, user of the LEAGUE]

    3. Select * from fnd_user where End_date is NULL; give me a count of 69 users, which users created by us are about 20 and we bought licenses approximately 40.  We need to have licenses for the rest 29 as well?

    4. we realized that it might be necessary to add the virtual machine additional JAVA in oacore (now 2), we need to have separate licenses for this (oacore, oc4j, Association etc.)?

    I have tried to find some references in the meantime and will appreciate if you have some references of loans.

  • Need information about type of screen for Satellite C50

    Hello

    Wondering if anyone could help clarify what the situation is in what regards the matte and glossy screens on the series C50. Ideally, the specific model numbers say that I'd get a matte screen? and also ideally on Amazon UK for example regarding the product links.

    What you need is a screen of 15.6 widescreen (13.6 "x 7.6") with a plug of 40 pins LED

    The part number isn't known to me and I think that this info would be very useful as reference numbers are Toshiba's internal reference numbers.

    If you want to buy a display of the independent garage, search in google SATELLITE - Matt of C50 has 15.6 widescreen

    I found some online resellers providing this part but don't want to post the link because I n t want to do a promotion.

    However, you can also get all the compatible parts of local authorized Toshiba service providers

    Hello

    My computer is a Satellite L10-PSL10E.
    The Bios is Phoenix V1.60 dated 21/12/04.
    There is a new Bios (v2.80 - WIN dated 07/08/07) available on the Toshiba web site.
    What's new in this version?
    Allows to start on an external hard drive or usb key?

    Is it recommended to install updates if all works well on the computer?

    If everything works you don't need new BIOS. Be happy with good running operating system.

    If you want to boot from the external HARD drive to use the other operating system, it won't work.

  • Portal of WC - need information about the Migration or DB tables for roles and users/groups.

    Hello

    We are to modernize the WebCenter portal for a client of 11.1.1.3.0 to 11.1.1.8.0.

    Anything can let me know the procedure of migration or the involved DB tables that store the roles and the "user groups &" under the administration of security.

    A manual level by recreating all roles and users and groups one by one is my last option.

    Thank you

    Jean Claude

    Hello.

    Do not recreate it manually.

    The documentation must guide for PS2 - PS7 migration explaining step by step what to do regarding the security / policies.

    Read it slowly and carefully.

    Using WLST backup/export/import of your policy store scripts / qualifications.

    Following links can help you understand the WLST Scripts for the migration of security:

    http://docs.Oracle.com/CD/E29542_01/core.1111/e10043/addlsecfea.htm#JISEC3639

    Custom security infrastructure controls WLST - 11g Release 1 (10.3.6)

    We have migrated many times of 11.1.1.4/5 to 11.1.1.8. Always on the PS3 (11.1.1.4) version.

    11.1.1.3 to 11.1.1.4 was the biggest change from my point of view. I never had the opportunity to PSx PS2.

    For migration tasks, my recommendation is to ask for doubts or things not clearly in Support of Oracle documentation.

    Kind regards.
