I have just upgraded myself to new version and started development in 9.0.1 Revision 20131022.0932 ( release 9.0.1). I have couple of small queries.
1) Am I using the right version for development or need to upgrade by implementing patches etc?. This is stable for development?
2) Previously I was developing applications on 8.5.2 but my clients were on 8.5.x and 9.x.
This migration is safe for existing applications? no crashes? no code mismatch? Is their any guideline for developer? Co-Existence of clients is possible?
Please guide me and thanks in advance
Best Regards,
Qaiser
In general, upgrading to the latest Designer version is ideal, especially with (as Per recommends) the latest fix packs, as well as on the server.
For non-XPage design elements, there should be no incompatibilities with 8.5.x through 9.0.1, so you're good there.
If you do XPages intended to be rendered by older versions (either older servers or XPiNC in older clients), you could run into trouble there, using properties and controls that don't exist there. You can mitigate that a bit by going to the app's "Xsp Properties" in Designer and changing the "Minimum Supported Release". That won't help you avoid trouble with third-party plugins not installed everywhere, but it helps with the core runtime controls.

Domino API is not available to be checked in the xpage properties of my databases
I am trying to use domino api to help with some of the recycling problems that we've had with xpages. I've spent days watching the various videos that have been made over the years. I have tried to get this working in both my work environment (9.0.1) and my home dev server (10). In both cases the result is the same - I have installed the extension library and domino api on the server via updatesite and it seems to be fine there. In my designer I can see that both extension library and domino api are installed (by looking in Application Management) but only extension library is available in the databases.
Need to be able to select the org.opentf library in the datbases.
We've tried to clarify in the release page. 4.2.x is for 9.0.1 FP9. Since 10 we've moved to updated version numbering, although Tycho doesn't make it straightforward. So 10.0.0 covers V10. The version in Notes needs to match the Notes version, not the Domino version. It's referenced for compiling only, not pulled into the design. So on the server, the version needs to match the Domino server version. So you may have different versions if DDE and the server are different. That's to do with how OSGi works.
We have SAP Hybris Commerce version 5.1.1 with custom extensions installed. Now we need to upgrade it to newest version 6.2.
My question is: Can we upgrade it to 6.2 and skip all versions between 5.1 and 6.2? Or must it be done by upgrading to 5.2, then to 5.3 and so on?
Yep - 5.1.1 to 6.2 ought to work (I've been working on a project that's done exactly this).
You will probably have to make some changes - watch out for any customisations you've made - it might be worth reading through the release docs to have an idea of what's changed - off the top of my head the structure of add ons is one area that's a bit different between 5.1 and 6.2, but otherwise things should work OK in theory.
Yes you can directly update to 6.2.
It's important to regulary update your hybris version. You should not have so much gap with current version. Indeed it become tougher to migrate your custom code.
Upgrading each minor version in a row is totally useless most of the time. Only do this if you have issues you can't solve while migrating to the target version.
You should take a look at this migration documentation and this guide (it can be used even if it doesn't match your version).
Note that some stuff like promotion are totally different in hybris 6 so you can expect some trouble to migrate everything. Take care of your extensions generated with old template also.
5.5.1 introduces JDK8 and Spring 4, I would not underestimate this change! Depending on the size of your project I would first go for 5.5.1. Also notice the MySQL change for 6.2 (5.6). Don't forget to declare deployment tables in your items.xml. Search for "third-party compatibility" and "release notes" on the wiki. Also try shifting to the backoffice since the hMC is marked as deprecated.
Yes you can migrate directly 6.2.
The time and difficulty depends on your custom code (and how much it respects good practices : naming conventions, usage of service, architecture respect...etc)
You might also consider that HMC is deprecated in 6.2
I would like to ask a question about wether or not I should do the migration to Liferay 6.2.
Me and my team are working since 4 month on a portal quite big developed with Liferay 6.1 (CE edition) and now, since the project publication date is still 4-5 month ahead (so I do have time), I was wondering if doing the migration to 6.2 now is a good choice.
I already tried the new version and I must say I am impressed about the new features and since now I haven't find any bugs.
Anyone had any experience on developing portlet/themes on Liferay 6.2? Is is worth it to do the migration now or shall I wait for the next ga2 release?
Any suggestion is very welcome.
Thanks
Depends mostly on the kind of work you've done on that portal. Even slight upgrades in Liferay, can have major differences in the source code. If this affects the work you've done, it will affect the upgrade too. For example, things will get difficult to update if :
You have developed custom portlets, as they will need recompilation for the new runtime
Developed Portlets that use ServiceBuilder might need more work than just a recompilation
Using Hooks (even simple jsp hooks) might need re-writing. ext hooks will almost certainly need to, and it can become a major pain
On, the other hand, if most of your work had to do with light theming and content management, it could become an relatively easy and painless upgrade.
In any case, make sure to keep a backup of your Liferay Database, because once you upgrade, there is no way to downgrade back to the initial version.
As you're using CE, my recommendation is to upgrade as soon as possible. Reason is that there are no more updates for 6.1, now that 6.2 is out. If you're going live in 5 months, you'd be on a version that's unsupported for half a year at the date of publication.
The alternative is to go to EE, which is supported for ~5 years from release, e.g. you'll have several years of support in front of you. However, as Liferay is paying my salary, note that I might be biased...
Of course, being unsupported "by Liferay" does not mean that you won't be able to fix any bugs or issues, but you'll have to do this on your own, and sooner or later you should upgrade anyway... If you're not yet live, I'm recommending to do it sooner.
Liferay 6.2 does not (yet) support as many marketplace apps as Liferay 6.1. Also Liferay 6.2 CE has bugs, and patches are available only to EE subscribers; this forced us to use Liferay 6.1 CE instead of 6.2 CE.
You will have issues if you are using the Vaadin framework under Liferay.
Liferay 6.2 CE does not support Vaadin out of the box ... it is delivered with Vaadin 6.8, but it is broken - your portlet code will break.
You would have to consider moving to Vaadin 7.1 at best ... and that is a non-trivial code migration as many items have been deprecated between 6.8 and 7.
I went that route and the learning curve was unexpectedly steep.
One of our customers have Lotus Notes version 5.0.9. They wanted to check if it's possible to create an android mobile application to connect to the backend for documents workflow.
Couldn't find much resources about this scenario for this version. I believe Domino is already available on that version - so is Xpages a viable solution for that scenario? Thanks.
XPages requires at least Domino 8.5.x (and preferably Domino 9.0 which is the latest IBM Domino release). So you need to upgrade the Domino server if you want to use XPages.
FYI: Notes 5 was released in 1999 (see the history of IBM Notes on wikipedia).
XPages are available since IBM Notes Version 8.5. The term "Domino" stands for the IBM Notes server. So if your customer has Notes version 5.0.9 they probably have Domino version 5.0.9 too (although one can mix Notes and Domino versions).
Therefore XPages are no option for your, apart from the fact you could install a second Domino sever with version 9.0 just to host the xpages.
If they are on R5 what are they using for a workflow engine? If they are using a database designed from Approval.ntf (I think R5 was the last time it was shipped with the product) then it is a very old and very difficult to maintain &/or modify. If so then they probably need to take a deep breath and upgrade and re-design. Can probably cobble something together to make it work but really question the wisdom of doing that.
I am wondering what level of support the latest MonoTouch has for using SQLite. The closest information I can find is this article here which referes to limited support in v1.2 however it concedes that you may run into run time errors while using this.
This is what I found on the Xamarin website: http://docs.xamarin.com/ios/Guides/Advanced_Topics/System.Data
This really scares me. Is there any documentation out there indicating what current level of support Xamarin has for SQLite?
I can't speak about the changes in System.Data support past that article, but I think it's quite common for folks to use csharp-sqlite, or better yet sqlite-net instead. Csharp-sqlite is an independent port of SQLite. And sqlite-net is "better yet" in the sense that its a minimal library where you can drop a single file in your project and use it to support sqlite on the various mono platforms. Yet it has nice features still such as "strongly typed queries" due to reflection-based ORM. So if you don't need a full Sqlite driver its a good option.
Greg Shackles did a nice seminar on x-platform dev with Monotouch/droid back in April where he covers these and other libraries: http://blog.xamarin.com/2012/04/25/cross-platform-mobile-development-seminar/
This link is outdated, it's about MonoTouch 1.2 and the latest MonoTouch's version is 6.0.
I'm using Sqlite with Vici CoolStorage in two apps on App Store: easy and no problems at all. I've never see any runtime errors using Sqlite.
