• What is the best way to transfer pictures from an old computer to a flash drive or a drive back then to a new computer?

  What is the best way to transfer pictures from an old computer to a flash drive or a drive back then to a new computer?

  The easiest and most reliable I've found is to make the direct drag-and-drop method.

  (1) on the old computer, open your Windows Explorer and go to your photos.

  (2) open another Windows Explorer window and access your 'Computer' folder and in your flash drive

  (3) drag the photos to the flash drive.

  (4) take the flash drive on the new computer and drag them into your images folder

• What is the best way to store the RCS for an insert/update in this rec

  Oracle on Win 64 non-conteneur 12.1.0.2

  When a record in one table is inserted or updated, what would be the best way to store the RCS for this record in this folder.

  I thought of a line after trigger, but did not know if this trigger to store the current_scn would still fire that trigger again (recursive trigger).

  Someone at - he a good idea of what the best way is to do?  The devs don't want to store the pk and the SNA in yet another table...

  Yes, row_dependencies would be the best way to go.  But mgmt doesn't recreate all tables for this.

  3rd party applications retrieve data from tables (all data).  We are looking for a way for them to just pull what is new or updated updated since their last sweater.

  I suggest that you try again and give all OF THE REQUIREMENTS.

  You have rejected ANY answer given and he justified using 'hidden' on what knowledge management or the devs want or do not want to. Stop making us guess what are the requirements and constraints. If you want a real answer then tell us ALL the news.

  When a record in one table is inserted or updated, what would be the best way to store the RCS for this record in this folder.

  Solomon answered repeatedly. If you want to add a column to a table to store the then "best" SNA is to let the Oracle to do this for you automatically by using the DEPENDENCY LINE.

  As he says also re-create the table to add this clause will be MUCH MORE EFFECTIVE that everything THAT you can do it manually. It will be also more accurate because Oracle will fill the value ORA_ROWSCN with the SNA at the time the line was committed. You, as long as user, can't fill a column in function when a line is engaged since real VALIDATION belongs to a transaction, not the line or the trigger that you use.

  Yes - there are two drawbacks to this method:

  1. you need to re-create the table

  2. you cannot add an index to this "hidden" column

  The devs don't want to store the pk and the SNA in yet another table...

  Then? Who cares what the devs want to do? You want the BEST solution? Next, you will need to put aside personal preferences and determine what is the 'best' solution. Why it is important that certain dev wants to do this or not?

  OK, the problem of biz is now, 3rd party external users are an all-wheel drive large number of tables in the database via the API that we wrote.  That was obviously interrupted OLTP during the day.  To reduce to the minimum, we want for them just to extract data that has been inserted/updated since their last sweater.

  It is the definition of a "replica" DB Then why don't you consider a real replicated DB? You can use DataGuard and have replicated DB which is read only that can be used to generate reports. Oracle does ALL the work to keep ALL the tables in sync. You and your developers do NOTHING!

  We thought that store the RCS higher their last sweater would allow the API to extract only data with YVERT higher than their last data pull CHN.

  OK - except you keep rejecting solutions actually do. Ask you questions about the SNA stored in the same table, but then reject the solution that does this. And then you add your "devs" don't want to store the info in a new table either.

  Then your solutions must ONLY use the replication or Log Miner. The REDO logs have all changes, if you want to extract yourself. Replication (e.g., DataGuard) will use these logs for you to maintain a replicated database.

  We thought about it, but recreate all tables in production with ROWDEPENDENCIES as well as dealing with CF and other dependencies idea this was shot.

  Well you NEVER mentioned you "thought that" and rejected it. And you NEVER mentioned anything about FKs and other dependencies. What is FKs and other dependencies which prevents this working solution? Tell us! Give us ALL the information.

  Wouldn't a trigger AFTER LINE capture the commit YVERT?  Or is after really not after validation?

  No - a trigger has NOT one commit. A trigger runs as a step in a transaction. Validation applies to the entire transaction. Until you, or Oracle, issues a commit, there is NO "committed SNA" to be stored as ORA_ROWSCN.

  You can easily see that for yourself. Create a simple table with dependencies of the line and then update two different sessions.

  create the table emp_scn rowdependencies in select * from emp where rownum<>

  Select empno, emp_scn ora_rowscn

  Update emp_scn set work = 'b' where empno = 7499

  commit;

  The first SELECT statement will show you that each row has the same SNA.

  EMPNO, ORA_ROWSCN

  7369,70622201

  7499,70622201

  7521,70622201

  Now, do the update (but no commit), then SELECT it

  EMPNO, ORA_ROWSCN

  7369,70622201

  7499,

  7521,70622201

  Where is the value of 7499? This session will NOT see a value for the changed lines in the current transaction. Other sessions will still see the old value.

  Now do the validation, then SELECT

  EMPNO, ORA_ROWSCN

  7369,70622201

  7499,70622301

  7521,70622201

  7499 now has a new and different value than the other lines. It will not be this new value until the validation occurs.

  Yes, row_dependencies would be the best way to go.  But mgmt doesn't recreate all tables for this.

  Well, you got the answer you want. You ask the best way. Now, you say that you were told the best way. But now you don't like the answer.

  How is it our fault? Your question has been answered wasn't she?

  Here are the facts:

  1 oracle creates a history of changes - the REDO log files

  2. you can use Log Miner to extract these changes

  3. you can create your own change log by adding a log file of MV to your table.

  4. you can then write a custom code to use this MV log file to determine which rows to "reproduce".

  So far reject you all THE POSSIBLE solutions.

  Accept it or change the requirements to allow one of the solutions proposed to be used.

  Personally, if I HAD to use a customized solution, I would use a MV journal to record the ROWID of the lines that have changed (for tables ROWID cannot be changed). I would then extract the appropriate lines by pulling on the lines corresponding to these row ID.

  Even that has problems since a line can be changed several times and children lines can also be amended several times - these questions FK you mentioned.

  I suggest you read this entire thread on AskTom a dozen years ago. It addresses ALL these issues.

• Best way to migrate the Apex in Production applications - how users are affected?

  
  Hello

  We have been migrating our apex in production applications after the opening hours to try to minimize the impact on users. Can the affected users if they use the application while migration is taken?

  It's how we migrate:

  -We export enforcement apex of the development environment. This creates a SQL file.

  -Then the SQL file is imported into the Production by using the option 'reuse application ID export file XX'

  Please let me know if there is a better way to move the application in production, and if the user isn't be affected if we during opening hours.

  Thank you

  Yes for sure users will be get affected when you replace the current with a new app, if they use it at the same time.

  Another best way to move the application to the production (keeping the same URL of deployment) is to use the Application Alias for your URL of the App Production.

  In this way, you can import the application while users are using the old application. And then after opening hours all you have to do is delete the alias from the application of the old app and assign this alias to your new application.

  Refer to the following response: Re: versioning in Apex (the thread is on version control, but, in this reply, I have explained the deployment of Application Alias method).

  I hope this helps!

  Kind regards

• What is the best way to move the data from the app and Server data structures?

  Hi guys,.
  
  I developed my application locally with Apex 4.2 and Oracle 11 g XE on Windows 7. Not far away, it is time to move the application to a server Oracle Apex. I guess that Exim is the way to go app. But what about the APA tables and data (tables/as 'customer' and 'account' created specially for the application)? I've been using a modeling tool, so I can run a DDL script to create the database server data structures. What is the best way to move the application data on the server? Is it possible to move the structures and data in a single process?
  
  Thank you

  There is probably another way to get here, but in Developer SQL, on the navigation tree, expand objects until your table, right-click, and then click EXPORT... you will see all the options. It is a tedious process and it sucks IMO, but yes, it works. This is zero especially because 1) it's a table at a time, 2) If your data model is robust and has constraints and sequences and triggers, then you will need to disable all for the insert and we hope you can re-enable constraints, etc. without hitch (good luck, unless you have only a handful of tables)

  I prefer to use the oracle EXP command-line to export an entire schema, then the server target, I use IMP to import the schema. In this way, it is almost true. This makes the dirty life if you develop multiple applications in a single schema, and I felt pain - however - it is much easier to drop the tables and other objects is to create them! (thus, even if the process of EXP/IMP moved more than you wanted to "move".. blow everything you don't want on the target after the fact...)

  You can use method datapump oracle too.

  If not, what can be done, IF you have access to both servers of your instance of SQL developer (or if you can tnsping both already from the command line, you can use SQL * MORE), is to run a script that will identify the objects of your applications apex (usually by the prefix for the names of objects, such as % EBA_PROJ_ etc.) and do all the manual work for you. I've created a script that does just that so that I can pass data from dev to prod servers on a dblink. It is difficult because of the order that must be executed to disable constraints and then turn it back on and of course, more complicated if don't always precede you ALL your "objects demand '... (tables, views, triggers, sequences, functions, procs, indexes, etc.)

• What is the best way to check the data

  What is the best way to check the actual changes in the data, i.e., to be able to see each insert, update, delete on a given line, when it happened, who did it, and what looked like to the front row and after the change?
  
  Currently, we have implemented our own audit infrastructure where we generate standard triggers and an audit table to store the OLD (values at the beginning of the Timekeeping point row before) and NEW (values at the beginning of the point of timing after line) values for each change.
  
  I put this strategy due to the performance impact there (important say least) and because it's something that a developer (confession, I'm the developer) came with, rather than something is a database administrator came with. I looked in the audit of the Oracle, but it doesn't seem like we would be able to go back and see what a line looked like at some point in time. I also watched flashbacks, but this seems like it would take a monumental amount of storage just to be able to go back a week, much less the years currently keep us these data.

  You can either:
  1. set up your own audit custom (as you do now)
  2 flashback Data Archive (11 g). Application for licence.
  3 version check your tables with Workspace Manager.

  Unfortunately, the audit of data always takes a lot of space. You should also consider the performance, as custom triggers and Workspace Manager will perform much slower than the FDA if there is heavy DML on the table.

• Need help: best way to exchange the Ipads?

  Dear all,

  Need help a genre:

  I use Ipad Air2 and my father is using retina Ipad Mini... I gifted him before 2 years...!

  We thought to share the Ipads because he loved the biggest... Can someone guide what is the best way to swap the parameters of the iPad?

  It is by taking backup and restore from Icloud? There will be data loss? or anything else that needs attention (something that he needed to be reconfigured)?

  Any help is very appreciated!

• What is the best way to use the Y50-70 battery please?

  and the best way to recharge.

  NOTE *.

  IAM always use the cable and I gave the battery except a few times.

  Thank you very much..

  Best way to use the battery, if your laptop should ALWAYS be connected in-

  Go to eat energy Lenovo - should be a RED icon in the system tray - and choose the mode for a better health of the battery (or battery Protection or health of battery optimized mode).

  I don't know what the energy Manager version you have, but the option must seem similar. What it does is, it will keep your battery charged ONLY up to 60 percent and will increase its service life.

• Photon: Best way to snap the back cover in place?

  What is the best way to put the cover back on? What sequence I use, it seems that one of the plastic snaps is not committed.

  There are instructions inside the battery cover. You start at the bottom and work your way up to the left and the right. That being said, check the clips on your lid and make sure that one of them is not folded. This happened to me the first day I bought the phone. I had to get a new one from the Sprint Store. Do not force the clip if it is wrong. I think that's how mine has folded.

• Best way to update the individual rows of a Table?

  I took a quick glance at a few examples, but did not get a clarification on this.  I am looking to have something close to a listbox control or the table to where I can update just one column of values to line a 1 time per second pace.  I'm looking to display our acquisition of data values in a table or a listbox control.  The single list box seemed to work well for that, but I couldn't use the row headers to list the names of channel beside the channel values.  I thought to link the values of cursor in two areas of list to do this, but did not find any info on it for the single list box.

  I have a few questions:

  (1) I have a 1 d table to where I want to use this data to constantly update the first column (with a multitude of lines) of a table.  I'm looking for the best route to not take too much time for treatment by doing this.

  What is the best way to update the individual rows of a table?   Invoke the node "Value of the cell value"... or is there another method?

  (2) why is that, after each iteration else, row values are deleted?

  Also, for adding additional channels originally arrray... it is better to use the 'Array' subset then the function "Construct the table" or function "Subset of the table" and "insert table"?

  See the attached example.

  Thank you.

  Jeff· Þ· Bohrer says:

  (2) why is that, after each iteration else, row values are deleted?

  Classic race condition.  dump the loop and node-p and just wire the 2D table on the terminal Board. !

  I don't see the race condition.  What I see is the table once the last element has been written for it all run the oil.  I saw looked it with point culminating performance on.

  But I agree entirely with writing to the Terminal.  It is a 1 d array, so you will need to use an array of generation and convert a 2D array in order so that he could write correctly.

  What is the best way to improve the performance of this all-in-one PC?

  Thanks in advance.

  Here are a few methods:

  • Run msconfig.exe, and then uncheck the startup tasks that you don't need. No matter what you disable, Windows always starts.
  • Use a light virus scanner, for example Microsoft Security Essentials.
  • Replace your magnetic drive with a Solid State Disk (SSD)
