Best practices for dealing with Exceptions on members of storage

• Best practices for JTables.

  Hello
  
  
  
  I'm programming in Java since 5 months ago. Now I am developing an application that uses charts to present information to a database. This is my first time manipulation of tables in Java. I read the tutorial Swing of the Sun on JTable and more information on other sites, but they are limited to the syntax of the table and not in best practices.
  
  
  
  So I decided what I think is a good way to manage data in a table, but I don't know which is the best way. Let me tell you the General steps that I'm going through:
  
  
  
  (1) I query the data from the employee of Java DB (with EclipseLink JPA) and load it into an ArrayList.
  
  (2) I use this list to create the JTable, prior transformation to an Object [] [] and it fuels a custom TableModel.
  
  (3) thereafter, if I need to get something on the table, I search on the list and then with the index resulting from it, I get it from the table. This is possible because I keep the same order of the rows on the table and on the list.
  
  (4) if I need to put something on the table, I do also on my list, and so on if I need to remove or edit an item.
  
  
  
  Is the technique that I use a best practice? I'm not sure that duty always synchronized table with the list is the best way to handle this, but I don't know how I would deal with comes with the table, for example to effectively find an item or to sort the array, without first on a list.
  
  
  
  Are there best practices in dealing with tables?
  
  
  
  Thank you!
  
  Francisco.

  You should never list directly update, wait for when you first create the list and add it to the TableModel. All future updates must be performed on the TableModel directly.

  See the [http://www.camick.com/java/blog.html?name=row-table-model url] Table of line by a model example of this approach. Also, follow the link BeanTableModel for a more complete example.

• Best practices for managing exceptions and success messages.

  Hey people,

  These days I've been shooting packages to clean my application. And question came to my mind, ' should I treat my exceptions the right way?

  
  So I want to ask you met guys, what is the best practice for this? (I want to learn it until it's too late )

  Currently I have a function that returns "OK" if all goes well.

  
  

  return('OK');  

  Can I manage my exceptions like this

    EXCEPTION
      WHEN OTHERS THEN
        ROLLBACK;
        RETURN (SQLERRM);
  
  

  At THE SUMMIT, I have a process that calls the function and then checks if the function returned "OK".

       IF cRet not LIKE 'OK%' THEN
        RAISE_APPLICATION_ERROR(-20000,cRet);
       END IF;
  
  

  And in 'process Error Message' I put "#SQLERRM_TEXT #" so that I can see what error occurred.

  Question aside, how do you manage your messages of success?

  Currently in 'process success Message' put something along the lines "Action completed successfully". What to do about all the processes.

  Do you want to do differently?

  I really want to hear what you have to say since I'm tired of feeling like this is a terrible way to manage these things.

  Hi Para,

  Para wrote:

  I don't know of situations where my service throw exceptions like no_data_found.

  and I need to know that the process is not so I can get to see my # #SQLERRM_TEXT.

  I got this by increasing the error in the application (which I think is a bad way to go) if the return is anything other than 'OK '. I get my application error in the process of the apex, and not in my service.
  And I want to show the inline error in the notification. (Which I am currently with my approach).

  You can use APEX_ERROR. ADD_ERROR in your PL/SQL process to throw exceptions in Oracle APEX.

• Best practices for network configuration of vSphere with two subnets?

  Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

  Install the most common iSCSI would be traffic between hosts and

  the storage is not being routed, because a router it could reduce performance.

  If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

  MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

  vMotion a deployment scenario might be something like:

  NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

  standby

  NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

  NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

  NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

  VMK (192.168.4.10) active

  You would place you on VLAN 10 storage with an IP address of something like target

  192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

  gateway configured in ESXi would be the router the VLAN 20 with an ip address of

  something like 192.168.2.1. I hope that scenario help set some options.

• I would like to know the "best practices" for unplugging my computer permanently to the internet and other updates.

  Thank you for taking the time to read this. I would like to know the "best practices" for unplugging my computer permanently to the internet and other updates. I thought I would do a clean install of Windows XP, install my Microsoft Works again and nothing else. I would like to effectively transforming my computer into a word processor. He continues more and more slow. I get blue screen errors, once again. I received excellent Microsoft Support when it happened before, but since my computer is around 13 years, I think it is not worth the headache to try to remedy. I ran the Windows 7 Upgrade Advisor, and my computer would not be able to upgrade. Please, can someone tell me how to make it only a word processor without updates or internet connection? (I already have a new computer with Microsoft Windows 7 Home Premium, it's the computer that I use. The old computer is just sitting there and once a week or so I updates.) I appreciate your time, thank you!

  Clean install XP sites
  You can choose which site to reinstall XP.

  Once it is installed, then you do not have to connect what anyone, however, some updates may be required to perform the work, test this by installing work and see if you get an error msg. Except that you should be fine.

• AF best practices for video

  I'm using an EOS 7 d for 1080 p HD video shooting. New to SLR camera and digital video. I have watched several tutorials but do not yet have a good understanding of what the best practices for the development.

  If I put the camera in AI Servo it will auto focus if the subject is moving away or toward me with depress me back AF-ON or the shutter button? Or should I press one of these buttons to make the camera continues to focus?

  You know tutorials or video lessons that cross using update with the video?

  Thanks in advance!

  I don't know any tutorials, but more serious videographers say it is best to use only the manual focus.

  Trial and error is a good teacher, when it comes to video DSLR. You'll quickly learn that video Auto Focus is really bad with the 7 d and most of the people do not use it all together.

  The method that works for me is to use AF before the filming of the video and then adjust manually if you want to you to shoot the video. With the help of f/8 or f/11 to keep everything in short without having to keep the setting.

  More recent Canon DSLR's like the T4i, T5i, 70 d and SL1 have a "hybrid AF" that does a much better job of AF during video, but it is not yet as good as a camcorder

• HP stream 11-d008tu: best practices for migrating to Windows 10?

  Hey there, I have a HP flow 11-d0008tu and received the notification I can upgrade to Windows 10. I want to do a clean install with a downloaded ISO but knowledge first of all, it is better to upgrade so that you get the activation done.

  Can someone give me some ideas on best practices for the upgrade? The stream has only 30GB HD so I have no recovery disk, I'll just do a recovery later on USB or SD card. When I do the upgrade can deselect recovery option or delete?

  Also, any other suggestions appreciated, especially which helps make effective for small HD

  See you soon

  Hi, I posted an installation procedure for Windows 10 fresh for the Tablet HP Stream here.  Also, I have a laptop 11 flow but do not have that yet. I think it must be the same because they both the same drive of mem 32 GB Hynix. A change would you probably want to use the 64-bit instead of 32-bit Windows 10 ISO file, the Tablet has only 1 GB of RAM.

• Just improved m tips on best practices for sharing files on a Server 2008 std.

  The field contains about 15 machines with two domain controllers, one's data is the app files / print etc...  I just upgraded from 2003 to 2008 and want to get advice on best practices for the establishment of a group of file sharing. Basically I want each user to have their their own records, but also a staff; folder. Since I am usually accustomed to using windows Explorer, I would like to know if these actions can be done in the best conditions. Also I noticed on 2008 there is a feature of contacts. How can it be used? I would like to message or send an email to users their file locations. Also, I want to implement an admin at a lower level to handle the actions without making them far in on the server, not sure.

  I read a certain bbut I don't like test direct more because it can cause problems. So basically a way short and neat to manage shares using the MMC, as well as the way that I approach their mail from the server of their actions. Maybe what kind of access cintrol or permissions are suitable also for documents. Also how can I have them use office templates without changing the format of the model.

• Best practices for vsphere 5.1

  where can I find the doc more up-to-date about berries EQL configuration / best practices with vmware vsphere 5.1

  Hello

  Here is a link to a PDF file that covers best practices for ESXi and EQL.

  Best EqualLogic practices ESX

  en.Community.Dell.com/.../20434601.aspx

  This doc mentions specifically that the storage Heartbeat VMKernel port is no longer necessary with ESXi v5.1.  VMware has corrected the problem that made it necessary.

  If you add it to a 5.1 system it will not hurt.  It will take an IP address for each node.

  If you upgrade 5.0 to 5.1, you can delete it later.

  Here is a link to VMware which addresses this issue and has links to other Dell documents which confirm also that it is fixed in 5.1.

• Best practices for color use in Adobe CC?

  Hi all

  Is there an article that describes the best practices for use of color in Adobe CC?

  I produce a mixture of viewing online (PDF, for the most part) and real world print projects - often with the obligation for both. I recently updated my PANTONE + bridge books for the first time in ages and I am suddenly confused by the use of Lab colors in the Adobe Suite (Illustrator and InDesign).

  Everything I found online, looks like Lab color mode preferred to use because it is device independent. And perceptual (on screen), it looks much closer to the color, it is trying to represent. But when I mark a Spot color Illustrator rectangle using laboratory coordinates, to the sides of a rectangle using PANTONE + bridge CP and then export it to PDF, the version of CP to mix CMYK color corresponds exactly to my Pantone book - while the version of laboratory (after converted to CMYK using the ink Manager) is far away.

  I have this fantasy to manage only a single Illustrator or InDesign file for both worlds (PDF) printed and online. Is not possible in practice?

  Any info describing the basic definitions of the color modes - or even a book tracing more than use them in the real world - would be much appreciated!

  Thank you

  Bob

  Here are a few best practices you can already do.

  1 make sure that your color settings are synchronized on all applications.

  2. use a CMYK profile appropriate for your print output. Lab spot colors convert to CMYK values based on the CMYK icc profile.

  3. include icc profiles when save or export pdf files

  In theory, your imagination is possible today. It requires color management and the use of icc profiles. You can place RGB images in InDesign and use Pantone colors in your objects. The problem lies in the printers. If a printer uses a RIP with built in Pantone library, the colors will match when printing. Unfortunately, this kind of CUT is more expensive and not enough printers use them. Most of them is always manually approximate CMYK values composition given Pantone colors.

• What are the best practices for creating only time data types, and not the Date

  Hi gurus,

  We use 12 c DB and we have a requirement to create the column with datatype of time only, if someone please describe what are the best practices for the creation of this.

  I would strongly appreciate ideas and suggestions.

  Kind regards
  Ranjan

  Hello

  How do you intend to use the time?

  If you are going to combine with DATEs or timestamps from a other source, then an INTERVAL DAY TO SECOND or NUMBER may be better.

  Will you need to perform arithmetic operations on time, for example, increase the time to 20%, or take an average?   If so, the NUMBER would be preferable.

  You are just going to display it?  In this case, DAY INTERVAL in SECONDS, DATE or VARCHAR2 would work.

  As Blushadow said, it depends.

• the best way to deal with the changed values maskMode?

  Hi people

  I just found out that the values listed for maskModes have changed between CC14 and CC15 who broke most of my scripts of masking.

  IE MaskMode.ADD in CC14 has the value 6413 but CC15 is 6813.

  What is the best way to deal with this? is there a simple solution or what I need to check the version of AE which is used and adjust from there?

  is there a direct way to access the name ie "MaskMode.ADD" instead of the value?

  Thanks... /JL

  To get the string maskMode by the current mask, you can loop through all the values possible maskmodes and stop when you click on:

  for (var k in MaskMode){
      if (myMask.maskMode === MaskMode[k]) break;
      };
  // at this stage k is the maskMode string (eg: "ADD")

• What are the best practices for a new employee to learn inside the instance of their business of Eloqua as efficiently as possible?

  We have companies everything changed at some point in our lives. And we all go through the process in the first weeks, where you feel new and are just trying to figure out how not to get lost on your way in the mornings.

  On top of that, trying to familiarize yourself with your new company Eloqua instance can be a daunting task, especially if it's a large organization.

  What are the best practices for new employees to learn as efficiently and effectively as possible?

  I am in this situation right now. Moved to a much larger organization. It is a huge task trying to understand all the ins and outs not only society, but also of the eloqua instance, especially when she is complex with many points of integration. I find that most of the learning happens when I really go do the work. I spent a ton of time going through the programs, documentation, integrations, etc., but after awhile, it's all just words on a page and not absorbed.

  The biggest thing that I recommend is to learn how and why things are made the way they are currently, ask lots of questions, don't assume not that things work the same as they did with your previous employer.

  Download some base in place level benchmarks to demonstrate additional improvement.

  Make a list of tasks in the long term. As a new pair of eyes, make a list of things you'd like to improve.

• Best practices for building an infrastructure of APEX for 12 c

  Thank you

  I agree with Scott's response '' it depends. '' It starts with the appropriate choice of a web listening port.

  You should discourage use EPG facility based in Production environments in accordance with the recommendation of the Oracle.

  Reference: See security considerations when you use the Embedded PL/SQL Gateway section.

  ADR (APEX Listener) + Oracle Weblogic Server sounds good, if you already have tried and have appropriate expertise to manage it.

  Also, you might consider what other facilities ADR based ADR + Apache Tomcat with Apache HTTP Server reverse proxy as described here:

  But it depends on Apache skills, you have within your organization.

• HTML and CSS best practices for Eloqua?

  Hello Topliners community,

  My name is Ben and I am a Web Designer. Currently looking for guidance on best practices in HTML and CSS when you work with Eloqua. I am interested in best practices for email and landing pages.

  Thank you

  Ben

  For landing pages, you can use a bit of HTML, CSS, and Javascript like on any other page. For example, we use the Bootstrap on a couple of our Eloqua landing pages.

  Support for HTML and CSS is much more limited. It is one of the best resources I've seen for CSS support:
