Replication setup time with 9i

Hi
Currently working on a design with the potential to use the Synchronous Multimaster Oracle9i replication utilising 2 hosts (master & backup).
I'd welcome feedback and experiences with regards to the time it took to setup the Oracle9i replication and the number of tasks involved.
As you have gathered I'm trying to get my head around the project cost this involves.

Setup shouldn't be a particularly large task, particularly if you've got some experienced DBA's. The Oracle Data Guard documentation is pretty thorough.
From a project planning standpoint, I'd be a lot more concerned about the ongoing maintenance tasks, particularly in a synchronous setup. You'll need to have at least two databases (the primary and one standby) operational in order to have either database accept transactions. If you're considering just a single primary and a single standby, they'd both have to be up for either to accept transactions. This may put a rather heavy burden on your maintenance folks if you can't accept downtime. Realistically, you'd want to have at least 3 machines if not more.

  • I am trying to setup VPN with QuickVPN

    Hi I am trying to setup VPN with WRVS4400N and Quick VPN on client side. I am fairly new to VPN and did some research and looked through the manual but can't seem to get it to work so far and from what I noticed many people are having this problem. So hopefully someone can tell what the problem is or at least point to right direction on solving this.
    Basically it gives the "Failed to establish connection" generic error, shows it almost instantly..
    It also showed the certificate error before but then I read about putting it in the installation directory and it stopped showing it, and whats strange is later I removed it but it doesnt show the error any longer, so don't know if its caching it somewhere or what can be going on...
    In effort to look for answer and test things out I tried to connect to another location and setup a WRV200 router, I also get the same error but not instantly, it even shows "Activating Policy" but then doesn't go farther and shows the generic error...
    Also with this setup strangly it always shows the certificate error, no matter if I put one in directory or not... Even tried to name it as the WRVS4400N certificate name...
    Anyway VPN IPSec is disabled, and Client Accounts are configured and changed password several times to make sure its correct, VPN Passthrough enabled on all 3 options.
    I tried to disable Windows Router, I also have a router in place do I possibly need to open some type of ports for the QuickVPN client?
    Don't know yet whats going on if I am missing something or if there is some problem that needs work-around but if you know the answer or guesses of answer please let me know.

    Hi Aleksandr,
    since this question is about a product in the Cisco Small Business / Linksys range, I suggest you move it to the community, where you will have a better chance of getting expert advice.

  • I am trying to setup time limits in airport 5.6

    I am trying to setup time limits for internet usage in airport 5.6—
    but i don't get a timed access control "option. Tried on both imac and macbook pro.

    What are you setting it up as.. join wireless network .. the very worst setup, it will disappear.. reboot the whole network in order modem. router TC.. clients and it will likely reappear.
    Tell us what network setup you are using..
    If you setup with cable to a computer completely isolated from the network with TC also isolated.. finish the setup of everything you want. .before update.. then plug it into the network. .then restart everything in correct order.. it will work most of the time.

  • Setup cocoon with 9ias 9.0.2 under windows NT

    Setup Cocoon with 9ias OC4J (9.0.2) under Windows NT
    This was a painful process for me. I finally made it work. Thought my story might help someone else. If anyone sees anything that could cause problems down the line, please let me know.
    NOTE: This took me a week to get right, so the restarts I suggest may not be appropriate, just guesses on my part.
    A. FIRST SECTION (Based off of steps 9 - 11 of Metalink note 148497.1) - This deploys the cocoon.war file
    1. Copy cocoon.war file to oracle 9ias home in the j2ee/home/applications directory. (NOT cocoon_jvm14. I tried to use the cocoon with jvm1.4. The version of 9ias I use wanted 1.3, so that is what I ended up using.)
    NOTE: I followed the 9-11 steps from the above note the first time and manually changed the files below, but when I had to reboot my machine a couple of days later it lost the changes. So I went in thru OEM and did it there and have had no problems. These steps are detailed below.
    2. Log into Oracle Enterprise Manager. Click on 9ias instance. Click OC4J_home.
    3. Go to Advanced Properties. Edit the default-web-site.xml file. Look for the statement <default-web-app application="default" name="defaultWebApp" root="/j2ee"/>. After that statement, add the following: <web-app application="default" name="cocoon" root="/cocoon"/>
    4. Go back to OC4J_home. Click on default link near the top of the page. (It has a Path underneath is that says application.xml) Then click on Advanced Properties. Edit the application.xml file. Look for the statement <web-module id="defaultWebApp" path="../../home/default-web-app"/>. After that statement, add the following: <web-module id="cocoon" path="../../home/applications/cocoon.war"/>.
    5. Go back to 9ias instance and do a "Restart All".
    B. SECOND SECTION ( Based off of Metalink note 184826.1)
    1. Go to the Apache/Apache/conf/mod_oc4j.conf file underneath your 9ias home. Add the following line at the bottom of the file: Oc4jMount /cocoon/* home
    Either "Restart All" from OEM again, or follow step 3 from the note. WARNING: I read somewhere that if you try to do the dos dcm/opmn stuff with the OEM at the same time, that you have corruption problems? So close the OEM if you do the dos commands just in case.
    C. THIRD SECTION (This is what I did with the Cocoon jars to make 9ias/oc4J find them and use them. I am by no means saying this is the correct way. Just a way. If anyone has a different way, I would appreciate hearing it.)
    1. Go to 9ias home and in the j2ee/home directory make a new folder. (I called mine xerces.) Copy the following jar files, found in the j2ee/home/applications/cocoon/web-inf/lib directory (this dir will show up after cocoon.war is deployed with the A. FIRST SECTION restart), into your new folder:
    a. batik-all-1.5b2.jar
    b. xalan-2.3.1.jar
    c. xercesImpl-2.0.0.jar
    d. xml-apis.jar
    2. Log into the Oracle Enterprise Manager. Click on OC4J_home. Click on Server Properties. Scroll down to the bottom and type the following into Java Options: -Djava.ext.dirs=xerces. (If you named your new folder xerces.)
    D. LAST SECTION
    1. I rebooted my machine and said a prayer. From the url "http://myhost:7777/cocoon/" I got the cocoon welcome page!

    I've heard rumors its about a month away. We were waiting for it, but then
    decided to go to Linux, as it probably performs better, and the release for
    Linux is already out. 9.0.2 is certified on Linux:
    - SuSe SLES7
    - Red Hat Advanced Server 2.1
    Waiting for Oracle to release a software product seems almost like waiting
    for a sunny day in Seattle -- you eventaly get it, but its unpredicatable
    as to when it will actually be at best...

  • Is it possible to get 2-ch signals from TDS2012 oscilloscope at the same time with LabVIEW "7.0"?

    Hi, everyone.
    I've been trying to get the signals from 2-ch of Tektronix TDS2012 oscilloscope at the same time using IVI connection with LabVIEW "7.0"
    I've already searched this developer zone for the answer.
    I've tried the famous example: "IviScope - Acq Dual Wfm Edge Triggered.vi"
    and it gave me the error message like:
    Error -1074110451 occurred at IviScope Initialize With Options.vi
    Possible reason(s):
    Driver Status:  (Hex 0xBFFA600D) Primary Error: (Hex 0xBFFA600D) The Config Server module is not present on the system.
    I think I've installed all~ the required softwares for IVI. For example, ICP 2.2, IVI engine 2.0.46, and tktds1k2k ivi (instrument driver for tds2012, in fact this one is for LabVIEW "7.1"... :-P)
    TDS2012 and my computer is connected through HPIB(GPIB) and it is shown on the MAX (a GPIB instrument as well as an IVI hardware asset)
    I've tried GPIB connection but it gives me asynchronous signals...
    Is it possible to get 2 signals at the same time with LabVIEW 7.0(not 7.1 or higher) by any means?
    What in the earth is the "Config Server" in this case?
    I don't need to sticking to IVI and any method to achieve my goal will be welcome.
    Could anyone give me the hint for this problem, plz?

    I think your problem is that the instrument specific driver is version 7.1 and you are using the class driver with 7.0. You can create your own 7.0 driver by downloading the LabWindows driver and using the Import CVI Instrument Driver under the Tools>Instrumentation menu.
    Since you don't seem to have a good reason to use IVI, why don't you try the native LabVIEW driver at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9139659CE034080020E748.... I believe you have all of the functions to setup each channel and then when you trigger the scope, both channels will be captured. You would then transfer each waveform separately. The data is always read sequentially but that's not important as long as both channels are triggered at the same time.

  • SWP works half the time with Vista 64, plus two installs

    Hey all,
     I understand now that SWP only works fully with vista 32 but I do have it working most of the time with vista 64.(only crashed once) My questions are
    1) For some reason on my uninstall folder it shows SWP twice.
    2) When I tried to uninstall one of them its said I was uninstalling part of windows, so I canceled it.
    3) Since its just for vista 32, will running it on vista 64 cause my computers security to be lower than normaL? I mean can a hacker take advantage of the fact that I'm running SWP on vista 64 even though its only made for vista 32.
    Thanks

    Hi Katrina, I am back again.
    Got my Vista-64Bit PC 2 days back. It has been a long 2 days. Today I am trying to get iTunes and my iPod setup, but I am not sure where to go from here.
    I did download iTunes-for Vista 64Bit and installed. Right away it updated to 8.1. No problems. I then copied my entire collection of songs (the same ones from my OLD PC, and managed by iTunes) from the external drive to the NEW C: Drive and to the exactly same named folder.
    Now I don't know how to proceed.
    In the NEW Vista environment, I don't find the same folder structure that was in the old XP PC. The new Vista PC has the following four places with any reference to iTunes and iPOD.
    1. Muisc/iTunes - has 4 files (iTunes Library. iTunes Library Extras, iTunes Library Genius, iTunes Music Library) and i folder (iTunes Music)
    2. C/PKM/iTUnes/iTUnes Music -- this is my creation, and this is where I have all muisc files/tracks etc, was and to be managed by iTunes from this location.
    3. C:/Program Files (X86)/ Apple Software - has 4 files and 3 folders
    4. C:/Program Files (X86)/ iTunes -- has 4 folders and 9 files.
    5. C:/Program Files (X86)/ iPod -- has 1 folder (bin) and 1 file.
    I do NOT see any files with *.itl type extensions.
    I had also exported my Playlists (the file name was music.xml)
    Katrina, where do I go from here? -- need to be able to use the librayr from my old PC, all Ratings from my OLD PC, and my playlists form Old PC, and of course the total libary from the old PC.
    I do have the complete file structures for the OLD PC where iTunes and Apple had saved files and folders - there were three places in addition to my own creation of the location where I ahd saved all the music files. Please let me know if you would like to see the folder structures.
    Thanks.

  • Routing setup Time based on material length

    Hi All,
    I have a situation where i have to write an Object Dependency to change the setup time of an operation based on the length of the material selected by the customer.
    For the first 5 inches, the Setup time should be 4Hrs, for each additional 5 inches the Setup time should be increased by 1Hr. there is no limit on the length they can select.
    I have created a Reference Characteristics SETUP_TIME, and have a Characteristic called LENGTH. I could use some help with writing the dependency.
    Thanks for the help.
    Raj

    Hello Raj,
    Please review the link . You can create a procedure as defined in this link.
    http://help.sap.com/saphelp_47x200/helpdata/EN/92/58c3a1417011d189ec0000e81ddfac/frameset.htm
    Eg ,
    $SELF.SETUP_TIME = MDATA $SELF.SETUP_TIME + 30 IF COLOR = 'FL'
    OR $SELF.SETUP_TIME = $SELF.SETUP_TIME + 30 IF METALLICEFFECT = u2018Yesu2019
    You should only usee MDATA if you reading the value from master data ,for a changed value you do not need to use MDATA.
    You can also achieve this by usingVariant functions in a procedure. You can write a code to do a calculation based on the values you are sending. Assign this FM (OD) to the reference characteristic. You can find more information on this on the following link.

  • How to move a database that is part of the replication setup

    Hi,
    We run bi-directional replication, setup as a "hub-spoke" , currently there is two active spoke databases, database version is 10.2.0.4
    The hub database needs to be moved to another server with another OS.
    How can we achieve this without having to re-instatiate the spokes?
    I can think of:
    exp/imp - probably not possible?
    Copy database files - the move is between servers with different endien, but RMAN convert can solve this?
    Can we create a a physical DG on the hub database, and even make the move more or less "online"?
    Please advice on the best way to move the hub database.
    regrds Curt

    Hi Curt,
    For RMAN convert, you need to have the same endian format for both the OS. Lets say if you are trying to move from Solaris 64bit (SPARC) to Linux 32bit/64bit then you can not use RMAN Convert since Solaris SPARC 64bit uses BIG Endian format while Linux (32/64bit) uses LITTLE Endian.
    I had a similat situation with Advanced Replication (not with streams) where we ended up in re-creating the Advanced Replication Setup. The export/import did not work since export/import will re-create the objects with a different object identifiers in the new database while the metadata refers to the old object identifiers.
    So the best option I see would be to move the hub and re-instantiate (just about setting the instantiation scn).
    Thanks,
    Rijesh

  • How to measure the Data setup time

    I want to do a SPI timing AC characteristics.
    I use labview capture a frame of SPI data package from a oscilloscope and display in a waveform Graph.
    Lead time, Data setup time, data hold time... should be measured.
    So, what is the next  step should i do?
    Thanks

    Thank you, asastet.
    I test the SPI module of a MCU. I have download a code to init the SPI and transfer a data package continuously.
    The 4 channels of oscilloscope connected with SS, CLK, MOSI, MISO.
    In labview, I capture a frame of SPI data package from oscilloscope and display in waveform graph control.
    My project will automatically measure the data setup time and data hold time according CLK vs. MOSI.
    Thanks.

  • VC - Dependency for routing setup time

    Hi all,
    During dependency editor programming, I had this difficulty with creating a procedure for summing up the setup time in the routing.
    We have 3 components A,B,C as multiple selection in a characteristic with variable BOM quantities.
    Based on the selection of these components, we have characteristics called QA,QB and QC to obtain the quantity of the respective components and pass it on to STPO-MENGE of the specific components.
    We have another procedure which sums up the total of QA, QB and QC and multiplies this to the setup time in the routing for a particular operation.
    The code for this dependency is:
    $SELF.SETUP_TIME = MDATA $SELF.SETUP_TIME * (QA + QB + QC).
    The issue we have here is the code calculates the setup time only if all the 3 characteristics QA,QB and QC is filled.
    We want the QA,QB and QC characteristics to be displayed only if that particular component is selected. Can anybody suggest how to code the procedure to output a sum even if one of the characteristics is not SPECIFIED.

    $SELF.SETUP_TIME = 0,
    $SELF.SETUP_TIME = $SELF.SETUP_TIME + QA
       IF QA SPECIFIED,
    $SELF.SETUP_TIME = $SELF.SETUP_TIME + QB
       IF QB SPECIFIED,
    $SELF.SETUP_TIME = $SELF.SETUP_TIME + QC
       IF QC SPECIFIED.

  • View Setup time in the DS planning board

    Hello Everyone. I maintained setup time for a resource but it is not displaying in DS planning board. What could have I missed? Thanks.
    Michelle

    hello,
    first check the operations of the order.
    right click on the produce operation and navigate to Order Processing.
    In the order tree open all nodes for operations.
    Is the set up activity visible there?
    If yes doble click on the activity.
    does the set up activity have a duration?
    If yes check the status of the set up activity.
    go back to the planning board.
    in the menue select extras-> Legend
    a pop-up with the graphical objects is displayed.
    Check the graphic objects for the activity status you read before.
    did you change the customizing settings for the graphic object?
    If yes check them again or reset them to the default SAP settings.
    I had a similar problem with a set up activity when I wanted to change the color of the activity according to the set up group. I  changed the settings in the customizing Maintain Planning Board Profiles.
    It is very difficult to maintain the decision table for graphical objects.
    If you did this recheck the decision table.
    Go back to the SAP default settings and check the planning board again.
    Are the set up acitvities displayed now?
    Then the porblem is with the decision table.
    rethink every step again.

  • Drop the Rules of one table from existing bi directional replication setup

    Hi All,
    I have one small question on bi directional replication setup, Its regarding table add in existing replication setup.
    What happened ,When we add a new table to existing replication setup if any reason table is not replicating between two database even we are not getting
    any error in dba_apply_error ,then we have to remove the rules for that particular table and setup again. Some time what happened we got error "queue has
    errors" i dont know the ORA number. But in that case what happened Apply process ABORETED and when we try to start the process it gives same error
    ("Queue has errors" ) and ABORTED again.
    then on metalink for doc id 203225.1 .we have remove the whole replication Manually and setup again. It's horriable....
    Could you please help that before drop the rules for particular table from exisitng bi directional replication setup then wht should we do ?
    Do we need to unscheduled the propagation process and then drop the rules becuase i read on metalink that reason behind the error ,queue has errors
    "negative rules drops while propagation process using the same rule set" .
    Please Suggest!!!!!!!!!!
    Many Thanks

    How huge those tables?. If those are small tables use Oracle MINUS function to get the defference records.

  • NI8451 SPI data transfer speed and SCLK setup time adjustment

    I'm using NI USB-8451 SPI bus to do communication. I can not reach the speed of communication 4MHz (NI USB-8451 module advertises speeds up to 12MHz). Actrually the data transfer speed is much slower than 4/8 Mb/s. The 16k*16bit data cost around 800ms while it should be 128ms if the data transfer achieves 4Mhz speed. In the manual there is a SPI timing clock figure like this:
     In the 4Mhz communication case,  the t2 should be 0.25us. I wonder whether the low data transfer speed is due to t1,t3 and t4 since they occupy too much "dead time". If my guess is right, is there any method to reduce the t1,t3 or t4, espetially t3? I know that in the advanced API there is a way to add delay while I did not figure out how to reduce delay(t3).  If my guess is wrong, what is the exactly maximum data transfer speed NI8451 can support? (not the clock rate)
     Thanks for help.

    Hi everyone. Im using the SPI communication with 8451 and Im having the same situation., since the serial flash memory I need to program is big enough, t3 (SCLK Setup time) and other "dead time" which I think is the time when buffer on the 8451 needs to be re-filled those are killing my expectation on the final results. I can't see a way to decrease t3 (~10uSec) and in the same way Im seeing something like buffering up to 100~110 bytes then, a ~1.5mSec delay appears on the signal waveforms. Did somebody have good results trying to avoid this?
    Thank you.

  • Setup time

    Hi, During confirmation with co11n, if the yield qty is more than 1, observed that the setup time is proposed as the setup time req for 1 qty only. it is not multiplied by operation qty. please advise what need to be done to get the total set time required for total yield qty. please advise.

    Dear ,
    What is the Setup Formula are u assining to your work centre -CR02-Capacity Tab /Scheduling -Execution Tab .
    I hope the standard one is  Set up Formula : SAP001 =SAP_01  , Here SAP_01 is a Time dimenstion with Min as Unit .There is no multiplication of Qty .You can chek the same in OP55 and then OP52
    Now , if you want to consider the operation qty which will be multiplied  , then you should go ahead with (OP55/OP52)
    SAP003 = SAP_03 * SAP_09 / SAP_08 / SAP_11    where SAP_03 --Lbr Hrs
                                                                                    SAP_09 -Operation Qty                                                                               
    SAP_08 -Base Qty ,  SAP_11-Operation Split timin
    Hope this is clear to u

  • Windows XP Setup Issues with MS-6368

    Hi,
    Today I purchased a new MSI-6368 motherboard.
    I decided to format my hard drive and start with a fresh install of Windows XP (something I've done dozens of times with many computers). The only thing I have replaced is the motherboard.
    The problem is, the system shuts down on its own everytime I run the Windows XP setup.
    The Windows XP Setup will spend a few minutes copying its necessary files to the hard drive. After that, it brings up a screen that tells me to hit ENTER to install, or R if I am doing a System Recovery. That screen stays up for about 3 seconds, then the entire system shuts down... even if I choose an option fast enough.
    I can do anything else with the computer without a problem. I did a full surface scan of my hard disk with Scandisk (which took well over an hour) with no problem. Its just the Windows XP Setup that shuts down the computer.
    Everything is up and running properly (fans, hard drives, disk drives, etc.) and everything else runs fine.
    I've tried changing everything I could think of in the BIOS (and even flashed the BIOS to the newest version), but nothing has made any difference.
    I know this may seem like a difficult problem, but I would really appreciate any help.
    Thanks,
    Kevin

    I've got the same board with no problems installing Windows XP, the only problem I have with the board is the very bad onboard video. I would check to make shure you have your BIOS options set correctly and your jumpers are set correctly on all of your drives.
