Change Date Original in EXIF?

I'm scanning some historical 35mm slides & negatives.
After importing into LR3, I used Edit Metadata Capture Time to change the date the original photos were taken. In EXIF Metadata I now have Date Time Original, Date Time Digitised & Date Time all the same = the original date I input. Clearly that isn't what I need! Any ideas how to change the dates "correctly" so that Original = date photo taken, Digitised = my scanning date. Presumeably the simple Date Time entry is the date & time last modified - or is it?
If LR3 wont change the dates, any suggestions on suitable Windows software to change Metadata info?

  • PSE 10 editor changing date taken in EXIF data

    Hello. I have just joined the forum after recently buying PSE 10 Editor for Mac. I had no trouble at first but now after I have saved an edit I  find that the date taken has been changed to the same as the date modified & imported.
    I can change it back manually through iPhotos menu but this is a bit of a nuisance when a lot of photos are involved, I don't know why it has happened but how do I reset it to give the correct date ?

    I hate to be the bearer of bad news, but it didn't help.  I lost another photo today and had to retrieve it
    for the Organizer from my Windows files.  Instead of placing it next to the original photo (or in the same area), it placed it in a file called Adobe/Photoshop.com.  I made sure again that the line you referred to isn't checked.  In addition, when the photo doesn't get lost, the Exif date for the photo does get lost and the photo is dated today.  These two problems seem to be connected, although I can never predict which one will occur.  Anybody have more ideas?  Could it be a Windows 7 issue rather than a Photoshop issue?

  • Batch Change "Date Modified" to match Exif Data After iPhoto Export

    Among several other posts about similar situations, I have found none that directly and simply resolve this issue.
    My wife imported a bunch of photos into iPhoto directly, but I wanted them in a folder on the hard drive.
    I pulled them out of iPhoto into a folder, then deleted the ones in iPhoto so that I could sort them and reimport.
    I then realized that the photos all now showed the date they were imported into iPhoto as their created/modified dates, which makes it impossible to easily sort them by the date of the pictures.
    I checked the Exif data, and it has preserved the correct creation date event though checking "info" on the pictures shows create date the same as modified the same as iPhoto import.
    Is there an easy way to batch change an entire folder of pictures to change the Created/Modified dates to match the Created date from the Exif data?
    The only other similar posts had answers that reccomend a piece of software that does not seem to actually do this, and one that suggests some sort of confusing script that I don't really understand.
    Please help - I have a bunch of family photos that I really need to fix.

    shootShifter helps to redate and rename complete folders of images based on the EXIF data or Finder dates.
    So it will do batches.
    I also believe that exporting the Original (File -> Export: Kind Original) will make all of this unnecessary.
    I don't like having them only in iPhoto so I organize the originals into folders by choronological event then import them so I have copies outside the iPhoto library to put elsewhere.
    You understand that you're using twice the disk space there, right? And that it's quite unnecessary. All iPhoto does is to put them in folders too. Have you looked inside the iPhoto Library ever?
    Go to your Pictures Folder and find the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed. Your photos are in the Masters folder.
    Standard warning: Don't change anything in the iPhoto Library Folder via the Finder or any other application. iPhoto depends on the structure as well as the contents of this folder. Moving things, renaming things,, deleting them or otherwise making changes will prevent iPhoto from working and could even cause you to damage or lose your photos.

  • In iPhoto 11 changing the Date and Time EXIF becomes Garbage?

    Hi- the new photo date I choose for a photo (say 1946) turns into garbage after saving - like 1165 or 1492- ( and Columbus would be suprised).
    Detail: About 5 years ago in Windows PC in  XP folders  I scanned old family pics into folder for 1946 and all was well= until few months back in 2011 I crossed over to Mac Book Air and  iPhoto 11.
    However iphoto  doesnt care for file name- Its sorts all in event date based on scan date- exif date-  embedded by the scanner when I did it. OK. Smarter.
    So to change its date I select each photo in iphoto11- then  select "change date" and changed the date what I want it to say (like   06/06/1946) - and saved .
    Problem. Now it has two dates against it - one date in year 1492 and the other in 1765- .
    I have tried changing the date differently using  the little Up or Down arrows, and its scrolls (eventually!) to 1946 -I  do a save..... and another crazy date turns up-
    Am guessing so its got to be a trick related to the " day counter"- mind you I dont see the pint of telling me that my photo is having its date changed by some quantity of thousands of days- Doh that sounds very Windows like.
    I must be doing it wrong.
    Any experts please?
    Thanks in advance !

    Thanks AppleMan1958, you're right.
    My view was set to Favorites and Unmarked so when I imported the video, rejected parts of it, and THEN changed the date I was unable to see that I wasn't changing the date on the rejected portion. I changed the view to All Clips (in the View menu) and then I could plainly see that the rejected clips still had the current date.

  • IPhoto changes the original creation date to 12/31/1969

    Hi folks, this is a problem I have been trying to resolve for a very long time.
    I have a large collection of pictures that I took with a Palm Zire 71 and Zire 72 going back to 2003. Every time I import the files with iPhoto (File > Import to Library), iPhoto changes the original creation dates of the jpgs to 12/31/1969. I have tried many different things... most recently I burned the files to a CD, confirmed that the original creation dates were still in tact, and tried importing with iPhoto right from the CD. I got the same result... all photos with the date 12/31/1969. All photos completely disorganized because of Palm's less than great file naming structure. I need to keep the creation dates intact for the iPhoto books I want to make with them, so changing the file names won't work as a solution. Even changing the files names to the creation dates plus a counter would be very difficult because it is over 1500 pictures. Does anyone else know of this problem and perhaps have a solution for it? Thanks!

    Thank you for the suggestion TD. But the Batch doesn't help in this case because so many of the photos were created on different days. I would still have to manually go into each of the creation dates and change them back to the original.
    That's just not feasible for 1500 files. iPhoto shouldn't be stripping the files of the creation dates at import to begin with. I'm hoping to find a way to get the import process to work properly for these files. The weird thing is that iPhoto doesn't seem to do this to files create on a more typical point and shoot camera,
    but only on these Palm files.

  • Changing date/time ...

    I have a question about changing date and time ... thanks a lot in advance.
    I have .CR2 files and I want to change the "date time original" info ... I want to change this info in the raw file, so I clicked on the "write date or time changes to into proprietary raw files" check box in the catalog settings window ... and then, after changing date/time with the "edit capture time", Lightroom wants to save changes and after clicking the arrow on the thumbnail, it creates a sidecar file. If date/time changes is to write directly into raw file (because of catalog settings indicated above), why does Lightroom create sidecar .xmp file?

    There are two things going on here.
    1. When you change the capture date/time (Date Time Original), the change is immediately reflected in the EXIF portion of the Metadata panel in the Library module. Because this is a metadata change, the warning arrow appears on the thumbnail (if you have that set to show in the View Options)....and clicking on that arrow brings up the "Metadata changed, do you want to save to disk" dialog. Note that this happens when you do any kind of metadata change, not just changing the date/time. At that point you can either decide to write the metadata to disk, or not.....if you typically write your metadata changes to XMP I guess you'd say "Save", but if you don't then just ignore it. Of course if you say "Save" then Lightroom will do as requested and write the Metadata, if it's a DNG,JPEG,TIFF etc, the Metadata is written to the XMP section of the file header....but if it's a proprietary RAW then it's written to an XMP sidecar.
    2. The second thing is that if you have the option set in the Catalog Settings to write date/time changes into proprietary raw files, then the change that you make is reflected in the Raw file.....this is a different change to the XMP update.

  • Can you help me about change data captures in 10.2.0.3

    Hi,
    I made research about Change Data Capture and I try to implement it between two databases for two small tables in 10g release 2.MY CDC implementation uses archive logs to replicate data.
    Change Data Capture Mode Asynchronous autolog archive mode..It works correctly( except for ddl).Now I have some questions about CDC implementation for large tables.
    I have one senario to implement but I do not find exactly how can I do it correctly.
    I have one table (name test) that consists of 100 000 000 rows , everyday 1 000 000 transections occurs on this table and I archive the old
    data more than one year manually.This table is in the source db.I want to replicate this table by using Change Data Capture to other stage database.
    There are some questions about my senario in the following.
    1.How can I make the first load operations? (test table has 100 000 000 rows in the source db)
    2.In CDC, it uses change table (name test_ch) it consists of extra rows related to opearations for stage table.But, I need the orjinal table (name test) for applicaton works in stage database.How can I move the data from change table (test_ch) to orjinal table (name test) in stage database? (I don't prefer to use view for test table)
    3.How can I remove some data from change table(name test_ch) in stage db?It cause problem or not?
    4.There is a way to replicate ddl operations between two database?
    5. How can I find the last applied log on stage db in CDC?How can I find archive gap between source db and stage db?
    6.How can I make the maintanence of change tables in stage db?

    Asynchronous CDC uses Streams to generate the change records. Basically, it is a pre-packaged DML Handler that converts the changes into inserts into the change table. You indicated that you want the changes to be written to the original table, which is the default behavior of Streams replication. That is why I recommended that you use Streams directly.
    <p>
    Yes, it is possible to capture changes from a production redo/archive log at another database. This capability is called "downstream" capture in the Streams manuals. You can configure this capability using the MAINTAIN_* procedures in DBMS_STREAMS_ADM package (where * is one of TABLES, SCHEMAS, or GLOBAL depending on the granularity of change capture).
    <p>
    A couple of tips for using these procedures for downstream capture:
    <br>1) Don't forget to set up log shipping to the downstream capture database. Log shipping is setup exactly the same way for Streams as for Data Guard. Instructions can be found in the Streams Replication Administrator's Guide. This configuration has probably already been done as part of your initial CDC setup.
    <br>2) Run the command at the database that will perform the downstream capture. This database can also be the destination (or target) database where the changes are to be applied.
    <br>3) Explicitly define the parameters capture_queue_name and apply_queue_name to be the same queue name. Example:
    <br>capture_queue_name=>'STRMADMIN.STREAMS_QUEUE'
    <br>apply_queue_name=>'STRMADMIN.STREAMS_QUEUE'

  • Identifying Changed Dates on Documents in SAP B1

    Greetingsu2026I have an unusual request that is somewhat long, very serious, and hope folks can help. 
    A headquarters customer believes a subsidiary company has u2018made upu2019 dates on invoices for previous billings.  They describe the date changes as u2018radicalu2019 but I have not personally seen these invoices as of yet and am waiting a FAX.  They requested I go into SAP B1 to see if someone has fabricated or made up or changed invoice dates and who it was.  They have some specific large-dollar invoices identified to research.  The person under suspect (who is no longer there) was considered an expert in SAP B1, so maybe she knew all of the different ways to change dates around.  Being an expert means also she might have used some unusual ways to change dates to the ones she wanted.
    Here are some of my ideas to discover this situation, but I hope someone can suggest even more steps because I would like to know every way that this situation can be discovered.
    1. Open the AR Invoices and use Data > Change Log and concentrate on dates.
    2. Run some SQL to validate document dates and system dates.  SELECT T0.DocNum, T0.DocDate, T0.CreateDate, T0.TaxDate, T0.UpdateDate FROM OINV T0 WHERE (T0.DocDate does not equal T0.CreateDate OR T0.TaxDate does not equal T0.CreateDate).  The results would show invoices that maybe had their dates changed.
    3.Run a Document Journal in the Financial Module.  Finance > Financial Reports > Accounting > Document Journal with the u2018Expanded Selectionu2019 of AR Invoices and a date range covering the invoices in question.  Then see if the Transaction Numbers are out of sequence.
    4. Run a Transaction Journal Report Financials > Financial Reports > Accounting > Transaction Journal Report with AR Invoices.  Compare this report to Document Journal.
    5. Run the Utilities functions of Utilities > Check Document Numbering to see if there any anomalies there in the document numbers.
    6. Run the Administration > System Initialization > Document Numbering function to see if a special series has been set up.
    7. Check out the AR Invoice numbering order by running another simple SQL covering a range of the invoices in question. SELECT T0.DocNum, T0.TaxDate, T0.CreateDate, T0.UpdateDate FROM OINV T0 WHERE T0.DocNum > 1583 AND T0.DocNum < 3251 ORDER BY T0.CreateDate.  Then see if the AR Invoice Numbering Sequence is not consistent.
    8. Check out those documents that are connected to each suspect AR Invoice and their associated dates by using the Target and Base Document icons.  For example, if a Deliver Document has dates of January 2007 but the AR Invoice date is September 2006, then someone has played around with dates on at least one of the documents.
    9. Get copies of the complete company database before the alleged changes were made and a company database as of today and compare the two contents.  Only good if the backups are maintained for a long time.
    Here come the questions on the ways I BELIEVE dates can be changed but not sure how to find and need to work on them:
    QUESTION 1 u2013 If a person DTWs invoices up into SAP B1, how can I tell that DTW was used to change the dates, the date of the DTW run, and the dates that were changed?
    QUESTION 2 u2013 If a person uses SQL to update dates on SAP B1, how can I find out that SQL has been used, the date of the SQL run, and the dates that were changed?
    QUESTION 3 u2013 If a person goes out and changes the workstation and/or server Date and Timestamp Properties, how can I find that they did that and the date changes?  You can do this on your PC by just changing the month, date, and year in Microsoftu2019s Date and Timestamp Properties.
    QUESTION 4 u2013 I know SAP has a policy that no SQL can be used to update databases and/or tables and have been told some customers lost support because they did this.  What does SAP do to discover this in their lab?
    QUESTION 5 u2013 Are there any notes in the portals to help me find changed dates?
    QUESTION 6 u2013 Are there any logs SAP B1 produces that can help identify such changes and how do I find and use them?
    QUESTION 7 (and this is big) u2013 Are the other ways dates can be changed on AR Invoices and how would I uncover the way it was done and the needed information of Original Date and Changed Date?
    Many, many thanks for any help provided since this is a serious situation.  If you can make any suggestions it would be greatly appreciatedu2026

    Hi Zal
    If this person was an "Expert" on SAP Business One then the only way they would have changed dates would probably be directly in SQL itself. The best way to determine this would be to hope that they slipped up somewhere and forgot to change a particular date in let's say one specific table.
    For invoices, start with the post date, doc date & create date. Then check each of these to the OJDT/JDT1 tables for any discrepancies. Next check the ADOC/ADO1 table for multiple instances on the invoice. If only 1 instance then check the create date, time & user as well as the aforementioned dates between OINV/INV1 & ADOC/ADO1. If multiple instances, check the dates from 1 instance to the next (This will indicate dates being changed in the system).
    Next check the same dates against OINM table. If any of the dates do not tally then the SQL was changed directly.
    Hope this helps. Let me know if you need further assistance.
    Kind regards

    Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
    This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
    Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
    When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
    If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
    Fixes people have used in the past included:
    Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
    Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
    Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
    Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
    HDD Fan Control
    HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.
    It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating
    Instead of HDDFan Control, get the free SSDFan Control

  • Approaches to transfer changed data from a table to another table

    Hello expert,
    will you please show me all approaches to automatically detect and transfer changed data from a table to another table ? I don't need detail information, but a little comment for those approaches are more welcome.
    Many Thanks,
    Edited by: 843178 on 19-Dec-2011 2:04 PM

    You will want to review information on replication and similar methods
    In a nutshell:
    Replication allowed data to exist at more than one site and take the Master / original table data and clone it at a different site
    As tranporting all of the table data to a remote / clone site got more and more expensive we developed a method
    to identify just the 'diffs' and only send those from the master to the clone which needed only the diffs to become a clone of the master table
    This has many methods and options, but looking under key words such as
    - distributed transations
    - materialized views
    - replication
    ... are a few categories that will get you started

  • Path problem during  Change of Original

    Hello,
    I am facing path problem while changing the Original file in a DIR.
    let say i created a DIR x and attached file a.txt from c:\ and  saved the DIR.
    Now if i use cv02 and select a original for change the popup window comes with data carrier and original file path  the path is shown as c:\a.txt which is actual original path.
    if i click on continue it is opening the c:\a.txt files and  changes are done on the original file on my pc.
    This way my original file is changed on pc and in DIR also.
    I want to know how to avoid this?.
    Regards
    Shiv

    That is why they call it document "Management".  The Original File is in the "Vault" where it can be managed, not on the desktop.  If you want to protect/save the file on your desktop, set the flag in the config of the workstation application to not allow "rename" of the temporary file.  You are just attempting to circumvent the intended design of the system. What you should really do is set the flag to "delete" the file after check-in.

  • PSE 8 - Changing Dates - Serious problem

    I have been using PSE for many years and have built up a library of almost 14,000 images, which are carefully tagged and dated, however I recently upgraded from PSE7 to PSE8 and, as recommended, I regenerated the thumbnails. I now find that PSE has changed the dates on about 4,000 of my photos and videos to the date of installation of PSE8 or of regeneration of thumbnails. The import date has remained unchanged but the date created and the date modified have both been changed on the file properties. The Exif Date as also been changed and mow matches the PSE Installation date as well.
    I am running Windows 7 and first installed the trial version of PSE8 while I waited for the boxed version to come.
    Since I am also experiencing some of the other bugs described in this forum, such as duplicated tags and the crashes when using people tagging etc. I am seriously thinking of going back to PSE7 and asking for a refund.
    Has anyone else experienced this problem?
    I did a backup of the catalog just before upgrading and I assume that I could restore that, and then import all the new pictures since the PSE8 upgrade.
    Does anyone have any recommendations for fixing this situation? I suppose I could deinstall PSE8 and PRE8, do a fresh install from the official disks, restore my PSE7 backup and reimport the recent photos. I have to say this sounds like a lot of work though.
    Peter

    Thanks for the reply, John.  After I wrote my post I found your comprehensive listing of resolved and unresolved problems with the PSE Organizer in 7 and 8 and saw that you had already found an unresolved issue with both 7 and 8 changing dates and times.
    I have not consciously changed anything at Photoshop.com.  I'm only using the on-line backup/synchronization as one form of back up.  I also back up to an external hard drive and DVDs.  But now that the main files are corrupted, later backups will be corrupted, too.
    I did have the advanced option to "Resolve backup/sync conflicts automatically" checked by mistake for awhile and I believe the date problem occurred while I had that option selected.  Now that I've de-selected that option, however, the improper dates/times keep regenerating themselves.
    This program is a quite disappointing upgrade, all in all.  As you note, it is a lot slower in several ways than PSE 7 was.  The program size may itself account for that since it is more than three times larger than 7 was.  What kind of programmer allows an automatic backup function to override dates and times which the user has specified in response to a dialog box which specifically asks you to specify dates and times?  And what kind of programmer hides the selection of file types for backup under "Advanced Backup/sync Options"?  Out of the box, PSE 8 has no files selected for backup.  The Backup/sync icon indicates that it's operating normally even when nothing at all is being backed up because you haven't clicked on any file types under "Advanced Backup/sync Options.
    I saw someone asking about other organizer programs for electronic photos and other files.  One which was not mentioned, which has a basically bulletproof organizer function, is Creative Memories Memory Manager 3 for about $40.  Editing features are quite limited, but functional with no glitches.  Organizing is the main thing here; editing is secondary, as you'd expect from a program aimed primarily at the digital scrapbooking market.  The entire program is very easy to learn and use and backups work without a hitch.  You could always edit in PSE and then use another program like Memory Manager 3 to organize your files as long as you don't save the edited files as .psd files.  See:  http://www.creativememories.com/MainMenu/Our-products-and-services/Digital-Scrapbooking/Me mory-Manager%c2%ae  The reason my wife and I moved to PSE from Memory Manager was the more sophisticated editing functions available in PSE, but by comparison PSE's Organizer is second rate, to be kind.
    >>> "John R. Ellis" <[email protected]> 12/29/2009 10:39 PM >>>
    Interesting, this is another symptom of a known bug: Photoshop.com doesn't handle unknown month, day, or time fields. (This is ironic, given that Adobe has been pushing a revision to its XMP standard specifically for handling unknown date/time fields.)  See this post for other issues wth Photoshop.com:
    http://forums.adobe.com/message/2306550#2306550
    After you first sync with Photoshop.com, you can see that the thumbnails on Photoshop.com have incorrect date/times.  But for me to reproduce your bug, I need to then change the tags or captions of the thumbnails on Photoshop.com.  Then when I sync again, the incorrect date/times get copied back into the PSE catalog. If I don't add a tag or caption on Photoshop.com, the incorrect date/times don't get copied back.
    Are you making any changes to the tags or captions of the photos on Photoshop.com?

  • Data, Original and Modified folders?

    sorry, this may be a dumb question, but what's the difference between Data, Original and Modified folders? when I do a search for a specific folder, i find that I will find all the folders and there looks like duplicates but they are filed in Data, Original and sometimes additionally under Modified.
    thanks!

    A Note about the iPhoto Library Folder:
    In this folder there are various files, which are the Library itself and some ancillary files. Then you have three folders
    Originals are the photos as they were downloaded from your camera or scanner.
    (ii) Modified contains edited pics, shots that you have cropped, rotated or changed in any way.
    (iii) Data holds the thumbnails the the app needs to show you the photos in the iPhoto Window.
    Please remember that Finder searches do not really understand your iPhoto Library. If you use iPhoto the correct way to search for photos is via the iPhoto Window.

Change Data Capture change sources, change sets, change tables, and subscriptions are exported and imported by the Oracle Data Pump expdp and impdp commands with the following restrictions:
    After a Data Pump full database import operation completes for a database containing AutoLog Change Data Capture objects, the following steps must be performed to restore these objects:
    1. The publisher must manually drop the change tables with the SQL DROP TABLE command. This is needed because the tables are imported without the accompanying Change Data Capture metadata.
    2. The publisher must re-create the AutoLog change sources, change sets, and change tables using the appropriate DBMS_CDC_PUBLISH procedures.
    3. Subscribers must re-create their subscriptions to the AutoLog change sets.

    Hello,
    I opened SR with Oracle Support, they are suggesting to perform full database import/export
    Change Data Capture change sources, change sets, change tables, and subscriptions are exported and imported by the Oracle Data Pump expdp and impdp commands with the following restrictions.
    Change Data Capture objects are exported and imported only as part of full database export and import operations (those in which the expdp and impdb commands specify the FULL=y parameter). Schema-level import and export operations include some underlying objects (for example, the table underlying a change table), but not the Change Data Capture metadata needed for change data capture to occur."
    CDC has different implementation methods:
    You may use the below query to determine-
    select SOURCE_NAME, SOURCE_DESCRIPTION, CREATED, SOURCE_TYPE, SOURCE_DATABASE, SOURCE_ENABLED from change_sources;
    – Synchronous CDC: with this implementation method you capture changes
    synchronously on the source database into change tables. This method uses
    internal database triggers to enable CDC. Capturing the change is part of the
    original transaction that introduces the change thus impacting the performance
    of the transaction.
    – Asynchronous Autolog CDC: this implementation method requires a staging
    database separate from the source database. Asynchronous Autolog CDC uses
    the database's redo transport services to transport redo log information from
    the source database to the staging database1. Changes are captured at the
    staging database. The impact to the source system is minimal, but there is some
    latency between the original transaction and the change being captured.
    As suggested in the document-
    Change Data Capture objects are exported and imported only as part of full database export and import operations (those in which the expdp and impdb commands specify the FULL=y parameter). Schema-level import and export
    operations include some underlying objects (for example, the table underlying a change table), but not the Change Data Capture metadata needed for change data capture to occur.
    ■ AutoLog change sources, change sets, and change tables are not supported.

    Re-Creating AutoLog Change Data Capture Objects After an Import Operation
    http://docs.oracle.com/cd/B19306_01/server.102/b14223/cdc.htm#i1027532
    After a Data Pump full database import operation completes for a database containing AutoLog Change Data Capture objects, the following steps must be performed to restore these objects:
    a. The publisher must manually drop the database objects underlying AutoLog Change Data Capture objects.
    b. The publisher must re-create the AutoLog change sources, change sets, and change tables using the appropriate DBMS_CDC_PUBLISH procedures.
    c. Subscribers must re-create their subscriptions to the AutoLog change sets.
