Best practices or design framework for designing processes in OSB(11g)

Hi all,
We have been working in oracle 10g, now in the new project we are going to use Soa suite 11g.For 10g we designed our services very similar to AIA framework. But in 11g since OSB is introduced we are not able to exactly fit the AIA framework here because OSB has a structure different than ESB.
Can anybody suggest best practices or some design framework for designing processes in OSB or 11g SOA Suite ?

Best practices to reduce downtime for Database releases(rolling changes)

Hi,
What are best practices to reduce downtime for database releases on 10.2.0.3? What DB changes can be rolling and what can't?
Thanks in advance.
Regards,
RJiv.

I would be very dubious about any sort of universal "best practices" here. Realistically, your practices need to be tailored to the application and the environment.
You can invest a lot of time, energy, and resources into minimizing downtime if that is the only goal. But you'll generally pay for that goal in terms of developer and admin time and effort, environmental complexity, etc. And you generally need to architect your application with rolling upgrades in mind, which necessitates potentially large amounts of redesign to existing applications. It may be perfectly acceptable to go full-bore into minimizing downtime if you are running Amazon.com and any downtime is unacceptable. Most organizations, however, need to balance downtime against other needs.
For example, you could radically minimize downtime by having a second active database, configuring Streams to replicate changes between the two master databases, and configure the middle tier environment so that you can point different middle tier servers against one or the other database. When you want to upgrade, you point all the middle tier servers against database A other than 1 that lives on a special URL. You upgrade database B (making sure to deal with the Streams replication environment properly depending on requirements) and do the smoke test against the special URL. When you determine that everything works, you configure all the app servers to point at B and have Streams replication process configured to replicate changes from the old data model to the new data model), upgrade B, repeat the smoke test, and then return the middle tier environment to the normal state of balancing between databases.
This lets you upgrade with 0 downtime. But you've got to license another primary database. And configure Streams. And write the replication code to propagate the changes on B during the time you're smoke testing A. And you need the middle tier infrastructure in place. And you're obviously going to be involving more admins than you would for a simpler deploy where you take things down, reboot, and bring things up. The test plan becomes more complicated as well since you need to practice this sort of thing in lower environments.

Best practice to define length for varchar field of table in sql server

What is best practice to define length for a varchar field in table
where field suppose Remarks By Person varchar(max) or varchar(4000)
Could it affect on optimization in future????
experts Reply Must ...
Dilip Patil..

Hi Dilip,
Varchar(n/max) is a variable-length, non-unicode character data. N defines the string length and can be a value from 1 through 8,000. Max indicates that the maximum storage size is 2^31-1 bytes (2 GB). The storage size is the actual length of the data entered
+ 2 bytes. We always use varchar when the sizes of the column data entries vary considerably. While if the filed data size might exceed 8,000 bytes in some way, we should use varchar(max).
So the conclusion is just like Uri said, use varchar(max) or varchar(4000) is depends on how much characters we are going to store.
The following document about varchar in SQL Server is for your reference:

Framework for parallel processing

Hello,
Can anyone help me by giving some links or examples as to how to use the framework for parallel processing ?? (FPP)
My scenario is that I have a report that handles huge volumes of data and process it. But at present my report is not able to handle huge volume and it either dumps or hangs. So I would want to use the parallel processing framework which would then can handle huge volumes and also reduce the time for execution.

Best practice in dreamweaver based web design

Hi DW Gurus
I have been learning dreamweaver at work and at home for a while now and I am very interested in getting some details about best practices.
I am aware that my designs are still quite simple and don't expand dreamweaver anyway near its abilities, however as a novice I am sticking with DW CS4 and trying to developing foundation skills before trying to move on to greater adventures in web design. My dream is to eventually leave my employer and start my own freelance design business that I can manage while I am travelling in SE Asia (yeah I know - dream on .....). I am saving for my CS4 master suite license - my current one belongs to my employer.
In particular I have just started to do some free design a community organisation - I am trying to develop a portfolio of sites that I can show new clients (with money) what they could expect for their investments.
I am interested in getting some ideas about work flows - design standards - whether designers use the dreamweaver layouts - whether to code or to use the WYSIWYG.
Anyone care to share how they plan and go about their design work.
In my past life I was a SQL developer and a C#.net programmer - in those feilds there are standards for code and applications . Are there industry standards that would point to good or better designing?
Thanks for your time and interest in my topic,
Respect,
Doug

The first thing you need to learn is html and css, without knowing the programming language will only make DW a hard tool to use. You need to learn coding to WC3 standards.

Hopefully you use Firefox, and if you do, the web developer toolbar is essential:

Yes, you can rely somewhat on DW's layout mode (or what features are left of it), but this will only lead to problems when it comes time to troubleshoot any problem pages that do not render correctly across the various browsers.
A paying client will expect a well designed, fully functional website and you need to have the programming skills to accomplish this for them.
Not sure how far advanced you are but the Adobe site has quite a few CSS based tutorials - and I would strongly urge you to go through the series listed below - to get up to speed on the correct way to lay out a page.

Best Practices or Project Template for Rep/Version

I have installed the Repository 6i (3) and created the users successfully, even though it has taken a lot of effort to make sure each step is correct.
However, on setting up the workareas and importing the project files, I have been trying back and force to figure out where things go, and who has what access.
Is there something like a best practice or a project template for setting up a basic repository/version control system, that provides
1. the repository structure,
2. corresponding file system structure (for different developers, build manager, etc)
3. access grants, and
4. work scenarios, etc.
The Technet demos and white papaers are either too high-level (basic), or too individual function oriented. I can't get a clear picture of the whole thing, since there are so many concepts and elements that don't easily go together.
Considering that I am a decent DBA and developer, it has taken me 2 weeks, and I am still not ready to sign up other developers to use this thing. How do you expect any small development teams to ever use it? It's one thing to design it to be scalable and all-possible, it's another to make it easily usable. I have been suggested to use MS VSS. The only reason I am still trying Ora-Rep is its promise to directly support Designer and Oracle objects.

Andy,
I have worked extensively with the Repository over the last year and a half. I have collected some of my experiences and the derived guidelines on using the Repository in real life in a number of papers that I will be presenting at ODTUG 2001, next week in San Diego. If you happen to be there (see www.odtug.com), come and see me and we could talk through your specific situation. If you are not and you are interested in those papers, drop me an Email and I could send them to you (they probably will also become available on OTN right after the ODTUG conference).
best regards,
Lucas

Best Practice Advice - Using ARD for Inventorying System Resources Info

Hello All,
I hope this is the place I can post a question like this. If not please direct me if there is another location for a topic of this nature.
We are in the process of utilizing ARD reporting for all the Macs in our district (3500 +/- a few here and there). I am looking for advice and would like some best practices ideas for a project like this. ANY and ALL advice is welcome. Scheduling reports, utilizing a task server as opposed to the Admin workstation, etc. I figured I could always learn from those with experience rather than trying to reinvent the wheel. Thanks for your time.

hey, i am also intrested in any tips. we are gearing up to use ARD for all of our macs current and future.
i am having a hard time with entering the user/pass for each machine, is there and eaiser way to do so? we dont have nearly as many macs running as you do but its still a pain to do each one over and over. any hints? or am i doing it wrong?
thanks

Best practices with LDIF Development for RBAC?

I'm currently working on enforcing RBAC (Role Based Access controls) in OID that may be subject to change every few months. What I've currently been doing is writing LDIF files to make changes to the existing RBAC once the changes have been finalized.
Unfortunately, now we have ended up with a growing list of LDIF files that must be run in sequential order if we were to build a new environment. Any defects or development errors that slip through developer unit testing must be handled in the same manner.
What is the best practice process for performing this type of development? Would it make more sense to have one LDIF file that removes all of the RBAC enforcement (via ldapmodify -c), and then a separate file that will install the latest and most up to date version? I've also considered just using one LDIF file, appending any updates to the end of it and using the ldapmodify command with the -c parameter

With regard to the 29.97/30 thing, you'll find that video people are idiosyncratically imprecise about that. We say 60 when we mean 59.94, we say 30 when we mean 29.97 and we say 24 when we mean 23.976.
We're quirky.
Whenever somebody says one of those nice, round numbers, you can assume they're really talking about the corresponding ugly fraction.
Unless they're film people, in which case +24 means 24, dangit.+

Best practice on calling an Oracle Bpel process

Trying to find the best practice calling an Oracle Bpel process. I know that I can call the process via database, app server, anothe bpel process, from an application, cron job, etc... I can do any of these but want some feed back on what others do and what method is the best.
Thanks

Your right there are a lot of different ways to call the BPEL WS. I guess what I'm asking is if you had several of these options at your disposal what way would you choose?
I have an asych bpel process that needs to be called once a day to move some data from one db to another. What do you think is the best way to perform this: from the db cron or Oracle job scheduler, the bpel manager on a timer, etc. I'm leaning towards calling it from the db via a cron or an oracle job. Want to know if there is a best practice for something like this.
Thanks

Best Practice setting up NICs for Hyper V 2008 r2

I am looking at some suggestions for best practice for setting up a hyper V 2008 r2 at a remote location with 5 nics, one for managment vlan and other 4 on the data vlan. This server will host 2 virtual machines, one is a DC and the other
is a member local DHCP server. The server is setup now with one nic on the management Vlan and the other nic's set to get there ip from the local dhcp server on on the host. We have the virtual networks setup in Hyper V to
point to each of the nics using the "external connection". The virtual servers 'DHCP and AD" have there own ip set within them. Issues we are seeing, when the site looses external connections for a while they cannot get ip
addresses from the local dhcp server anymore.
1. NIC on management Vlan -- IP Static -- Physical host
2. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- virtual server DHCP
3. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- Virtual server domain controller
4. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- extra
5. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- extra
Thanks in advance

Looks like you may be over complicating things here. More and more of the recommendations from Microsoft at this point would be to create a Logical Switch and then layer on Logical Networks for your management layers, but here is what I would do for
you simple remote office.
Management NIC: Looks good (Teaming would be better, but only if you had 2 different switching to protect against link failures at the switch level. Doesn't seem relevant in this case however.
NIC for Data Network VLAN: I would use one NIC in your case if you can have the ability to Trunk multiple VLANs at the switch level to the NIC. That way you are setting the VLAN on the VMs NIC that you want to access and your
Virtual Switch configuration is very simple. On this virtual switch however, I would uncheck IPv4 and IPv6. There is no need to give this NIC an address as you are just passing traffic through them from the VMs that are marked with VLAN tags. Again,
if you have multiple physical switches in the building teaming could be an option, but probably adds more complexity than is necessary for a small office.
Even if you keep your Virtual Switches linked to separate NICs unchecking IPv4 and IPv6 makes sense.
Disable all the other NICs
Beyond that, check your routing. Can you ping between all hosts when there is not interruption? What DHCP server are they getting there addresses on normally? Where are your name resolution servers (DNS, WINS)?
No silver bullet here, but maybe a step in the right direction.

Best Practice : Creating Custom Renderer for Standard Component

I've been reading the docs and a few threads about Custom Renderers. The best practice seems to be to create a Custom Component where you need a Custom Renderer. Is this the case?
See [this post|http://forums.sun.com/thread.jspa?forumID=427&threadID=520422]
I've created several Custom Renderers to override the HTML provided by the Standard Components, however I can't see the benefit in also creating a Custom Component when the behaviour of the standard component is just fine.
Thanks,
Damian.

It all depends on what you are trying to accomplish. Generally speaking if all you need is for the user interface output to be changed then a renderer will work just fine. A new component is usually made in order to provide some fundamental change in server side functionality not related to the user interface. - Ponderator

Best Practices: iPad/MacBookPro synching for video production in education

My organization just bought 14 Macbook Pros and 14 iPads Minis. Our goal is to have students in single-day classes use the iPads to film something, then synch/export the video to a MacBook Pro where they can then edit that video in iMovies. Once that single-day class is over, all of the video will (likely) be deleted and new students come in a couple days later and start fresh. I'm trying to figure out the best practices for this to make it as painless as possible for all involved.
So, matching AppleIDs for each pair? One AppleID for all devices and manual synch through iTunes? Dropbox/cloud synching instead of iTunes?
All of these devices are brand new. I have already started prepping the MacBook Pros, but have not even turned on the iPads since I'm not sure which AppleID I should attach to the iPads -- I assume the first AppleID on an iPad will accept the iLife apps much the same way they do on the MacBook Pros.
Any help is appreciated.
Thanks
Jack

well the most important fact to accept is that ALL DRIVES WILL FAIL. It's just a matter of when. I can tell you about a nightmare situation with g-drives (before Hitachi bought them). What format are you shooting? If you shoot on tape, you can always recapture as long as you captured with abort clips on dropped frames on make new clip on timecode break are enabled. But that's gonna take "real time." If you shot on a chip based format, backing up the chips in multiple places (and I mean multiple) can provide a sense of security. But if you need to be able to get back to work immediately if you have a drive fail, having a back up of your media or if you've stored it on a redundant raid is crucial. I also seriously recommended having a clone of your startup drive so if your startup (boot) drive fails, you can get back to work quickly.
