BW Upgrade and in parallel development

hi ,
I have some doubts abt in parallel development with bi upgrade.hope someone could clear my doubts on this.
Currently, I'm working on a development request that involves ODS/Cube/Infoobject change.All this are done in dev 3.5x.
Parallely, there is another bi team that's working on the upgrade activity which will upgrade this bw 3.5x to Bi7.0. Issue is that no freeze on development done during this upgrade activity. both development and upgrade is being carried out in parallel by 2 teams.
questions :
1.can anyone highlight the impact of this parallel activity
2.if i choose to stop the development work now temporarily, can i use the same transport request number which was generated in BW 3.5 dev and transport to new BI 7.0 production? or should i choose to recollect the objects again in BI 7.0 environment and continue development after the upgrade activity completed?
3.will i face any compatibility issue later if i stop the development work half way now?
4.Is there any other risk of in parallel dev and upgrade?
Hope someone could advice me on this.
Thank you.
Regards,
Maili

Infoproviders are version independent. While BW 7.x has different names for ODS (DSO) and additional features, there is no 'conversion' process per se at the infoprovider level. BW 7.x does provide new data transformation and data flow methodologies, but the BW 3.x methods are still functional in the BW 7.x environment.
However.. you will need to release and migrate your 3.x development transports before you perform the BASIS level conversion programs. You will not be able to 'keep them open'. So based on this factor alone, you will need to either
A) create and manage a dual development environment.
B) establish a development "Freeze" schedule that follows your overall development program.
When we converted from BW 3.5 to 7.0, we established a freeze.

Versioning and parallel development streams for worldwide SAP roll-out

Hi SDN folks,
My customer is in the process of a worldwide roll-out of SAP. They have a transport environment for ECC that looks like this:
D -
>    QA -
> R   -
>   P
We have SAP Charm installed and running in solution manager - to manage the creation of transports in the D system.
The problem we are facing is how to manage parallel development changes and configuration changes.
For example - if we have developers working on a change that is in test in the QA environment - and we hit a production emergency in P - we then need to make an emergency change to the P version (which would only be available in P and R) - and transport this change through to P - in the process - overwriting the changes that our developers are working on in the D and QA environments.
We also have the issue of objects for multiple countries being developed and configured in parallel - and so there will be version conflicts up the to the QA system as well.
Is there any kind of solution for the management of parallel development streams - and versioning - for all custom code / development objects and for configuration changes(other than introducing a second development system)?
Is there any kind of 3rd party product for SAP that helps to solve this issue?
Currently we are considering development freezes, manually renaming objects with versioning identifiers (will only work for some objects), manual backups of versions. - none of these seem to be a tidy universal solution, is there one?
Any help / directions you can offer will be appreciated,
many thanks,
Julian

Hi Julian,
Thanks for the clarification!
Managing production support and new development after go live is always a challenge. It can be addressed in many ways, but it is most important to create a set of rules and stick to the procedure. If you do not want a "second" landscape, you are going to have objects "overwritten" in the D and Q systems when you need to make a production fix -- as you must revert the object in D to the P version to make the fix. Even with a second landscape, objects will have to be merged somehow when a fix is promoted to production.
As I said above, what you can do is have your developers save their current development in released transports before making the production fix. This saves a version that must be merged with the fix, anyway. That is:
Object A is the produciton version and must be fixed.
Object A' is the current development version (unfinished) and is saved into a released transport request.
In D, Object A' is reverted to the A version and corrected for the production error, creating object A'' that is promoted to production.
Object A' and A'' are manually "merged" into A''' as the new current development version.
Yes, objects are overwritten with this method. However, you can always retrieve what has been overwritten since it has been saved in a released transport.
Another option is to bypass Q for production fixes. I.e. D -> R -> P. However, this invalidates the objects in Q until the merged version is created in D and transported to Q.
In any method you choose to do this -- dual development landscapes or not -- discipline and managment are a must.
Best Regards,
Matt

Parallel development with ClearCase and Jdev

I am looking for information on "best practices", howtos, etc for configuring a ClearCase VOB repository to support parallel development of J2EE applications/components using JDeveloper in a large development team.
In particular, I am not sure how to set up the code repository (AND JDeveloper) to deal with JDeveloper's project file structure and the various metadata that are created for each developer at the same time as you need to work transparently with an exisiting repository of Java components which have already been developed and are managed outside of JDeveloper and ADF.
Unless I have missed it...documentation seems to be a bit thin in this area so...
TIA for any help/advice/pointers

I'm searching for other peoples experience developing an application that could run with either postgres 8 or Oracle 10g.
The reason of course is that many of our customers don't have the money for Oracle, but we do want to use and RDBMS.
The logical thought is that as long as the database objects are the same, the application isn't going to be that different.The other logical thought is that if you don't use any Oracle specific features then customers who have paid money for Oracle will have just wasted that investment when it comes to running such an application.
So why bother with Oracle.
The simplest way to have a single code base is to develop for a single database, the cheapest lowest common denominator and just give the customer the database with the application.
If that is true that it would greatly help the development team since they would not have to have separate teams for each type of database.But it will not be a great help to the development team if they can only use functionality that is available on both databases and works the same way on both databases. It will be a really big hindrance to the development team, increase development time and lead to more code that needs to be written.
>
But before we start down that path we are trying to find out if anyone else is doing something similar, and what the overall experience has been.
I have seen several applications developed using this single code base for multiple database approach and they have all been inefficient when running on Oracle to the extent that you wish they had used a flat file and hadn't bothered with a database at all.

Best Practice of Parallel Development Lifecycles

Dear all,
Looking for some best practice information regarding the Parallel Development Lifecycles used either for the system upgrade or phased implementation. I need to understand the way how to change the object ownership while merge the two lifecycles into one production system.
Any help and/or direction is appreciated.

Is parallel development possible?

Hi,
Is parallel development possible using Policy Studio?
Assume that there is a team of 5 developers working on multiple policies at the same time and perform deployments at frequent intervals - is this scenario possible?
Asking this as me and my team met with deployment issues as listed below:
1) My copy of a specific container would be different from the one on a team mate's one - as I started creating policies after the team mate started with his work
2) Once a team mate deployed his/her artefacts, I would lose my artefacts (which the team mate was not having) which I was having on my container

Hi,
The short answer is no and in my opinion the biggest flaw with the API Server at the moment. I know for a fact this is something that is being worked for future releases but no idea when or exactly how it will work but it is a major update.
I work in a similar environment as you are describing and this is how I have implemented our process.
In our Dev environment we have one instance per developer, so each developer can work 100% independently. When the development is done and somewhat tested we export that sub-set of policies and check in to our version control system. We have one person responsible to deploy the exported policies into Test, which usually include updating some specific environment settings (updating URL's etc) and after this we do some regression testing.
One challenge is to be clear of what to export and not, for example LDAP connections. We have the LDAP connection already in test and we make sure this is not included in the Export but still there is a soft reference to this LDAP connection and this will work fine as long the connection is identical between the environments. This is best achieved if a "standard configuration" is made (including all settings for common flows as for example LDAP etc.) and that is being used as a base for the development environments. If there is a need to add common items, for example a new Root CA this should be done centrally and make sure all dev instances get the exact same update.

Libros y Audiolibros en Español--cannot upgrade, and cannot purchase audiobooks.

Two major problems with this App.
One, I cannot successfully purchase an audiobook through the app. I can download a free text-only book, but there are no free audiobooks that I've found. When I try to purchase an audiobook, it goes through the BlackBerry World sign in, I put in my password, it verifies my account, and then says "content not available". I have tried several different book. I have no problem at all purchasing apps through BB World, and there is no problem with my PAyPAl or credit card accounts.
Two, I have version 1.0.xxx of this app. In BB World it says version 2.1 is available for upgrade, and when I click upgrade it gives the install bar, but doesn't upgrade. If I go into BB World on the Internet and choose to download this app, it says it is giveing me version 2.1, but after it has downloaded and installed on the BB Z10, it still is version 1.0.xxx and says there is an upgrade to 2.1 available. I have tried first deleting version 1.0.xxx, hard rebooting the Z10, reinstalling what is said to be v 2.1, but no luck.
I have emailed the developer in Spain (in Spanish) and received no response from them.
My Z10 OS is 10.1.0.2354, an offical release, and is working well.
Any ideas, anyone?

Upgrade from SQL server developer 2008 R2 to SQL Server developer 2012

Hi,
We have bought 5 licenses of SQL server developer 2012.
This licenses provided us an option to use SQL server 2008 R2. And we have been using 2008 R2 till now.
But now we want to upgrade to SQL server developer 2012 edition
I want to know the process for up-gradation. When I looked at the licensing portal, it says "This product does not require a product key"
My questions are:
1) Should I download the 2012 version from licensing center and pass the downloaded copy to respective team members?
2) Can the team member download the SQL server 2012 developer edition from Microsoft site and install it on their machines?
3) Do we need to first un-install 2008 R2?
4) How the licensing can be managed in cases of products which say "This product does not require a product key.", i.e. how can I make sure that no more than 5 installations are done by the team
Thanks

1. Developer edition has license associated with it .And yes you can download it if you have subscription.But please be informed that you cannot use Developer edition in production,its not allowed and illegal.
2.You can upgarde from SQL server 2008 R2 to 2012 developer edition by Inplace upgrade method ,you can also follow side by side approach.For side by side approach you have to get new box ,intall OS,then install SQL server 2012 ,move logins and jobs and move
databases by backup restore.You must see supported upgrades
http://technet.microsoft.com/en-us/library/ms143393(v=sql.110).aspx
3.No not ins any case ,please dont do that
4.Licensing question should best be asked with Microsoft licensing expert.
reg process of upgarde first run upgrade advisor and look for error if any.Then run SQL server 2012 setup and in maintenance section select edition upgrade,other process is same as SQL Server installtion

How to upgrade AND move between platforms with different Endians...?

Hi, all,
I have two databases - one of 500Gb and one of 50Gb - that are currently running on 10.2.0.4 on AIX 64-bit. They are Production systems.
I have to move them to a brand new Linux (RHEL 5.6 - 64-bit) server that will be running 11.2.0.2.
For test, I'm OK with this being done with Data Pump. But for the eventual move to 'New Prod', this will result in hours' worth of downtime and it's a business-critical system, so I'm trying to mitigate that as much as I can.
I was, naively, hoping to use RMAN to both move the databases from one box to the other, but also to upgrade them. I figure I would do the following (as per Metalink 369644.1) as I have a Recovery Catalog, etc, etc:
Install the binaries on the New Prod server
Connect to the RCAT and restore the database and recovery to a PiT
Manually upgrade the database by putting the DB into STARTUP UPGRADE and running the catupgrd.sql
Unfortunately, I didn't realise the Endian was different between AIX and RHEL (as per 1079563.1). Oops.
It doesn't look like I'll be able to use Transportable Tablespaces (as per 243304.1) either without first having to migrate the data across as a 10g DB and then upgrading.
So my options appear to be:
a) Data Pump and suck the outage up
b) Move the data using Transportable Tablespaces to 10.2.0.4 and then upgrade to 11.2.0.2.
Are there any other options? I have hopes that a logical standby would work in this instance a la rolling upgrade, but suspect that the different O/S AND the different Endian would scupper that idea...

Perhaps, I have more experience using concurrent exports/imports using the traditional exp/imp utility than using the parallel option on expdp/impdp. One thing you can do with exp/imp that you cannot do with expdp/impdp is export into a named pipe, start a remove copy of the named pipe to the new server, and then start importing from the named pipe on the new server so that you are importing while still exporting the same objects. We use tables= exports when we did this back when the tables= parameter could only handle 99 tables. We had a separate export for every large table and then a set of exports for 99 tables for each of the other tasks ran 6 to 12 concurrent processes.
One thing to look at is historic data. Potentially some tables can be moved in advance of the majority of the application objects and replaced with synonym to remote objects.
Truely static tables could also potentially be moved in advance even if only a day or two before to reduce the number of objects to be moved.
Build the new database in noarchive log mode to save some processing and switch it over and immediately back it up when you migrate.
And Yes, if the two platforms appear in the view name I gave you then you can use transportable tablespaces with the rman conversion step. Instructions for using rman to do the conversion are in the rman manual.

Combined Upgrade and Unicode Conversion

Hello, I'm planning to implement an Upgrade from I386/ORA8/46C TO I386/ORA10/ECC6 using CUUC method.
According to the guide, I better build up a sperate Sandbox Server for ABAP Program Modification and Testing. Since the customed ABAP Reports used to be related with the customed table, I suppose the best way for the Sandbox Server is to upgrade it to higher version.
I'm running the Prepare and stuck on the Transport Request import. The sandbox server is not ready yet in a few days.
My question is, can I just ignore the ABAP Program Import at the current phase and import it at the end of 'Prepare' and before the 'Upgrade'.
If yes, how? mannually import the TR for Abap Program changes to 46c after the 'Prepare' finished? Any steps that I should pay attention to spcially?
Any experience is welcome.
Thanks in advance and BR, Sam

This would depend on whether your quality and production are consistent in terms of modifications along with your development server. If all changes to quality and production has happened through changes in development and then transporting those changes to qas and prd, then i would suggest when you run your development system upgrade (sandbox in this case) ideally you should do the changes and modifications and record them in transport request using the option "select for transport". Later when you upgrade another sandbox (copy of qas or prd) you should select the transport request to be imported during the prepare.
But as you are now running PREPARE for copy of development, the prompt for importing transport request into this system is irrelevant and you should say " no" and complete the upgrade, and then the process outlined above..
Hope this helps.
Cheers,
Chetan

Windows 7 Upgrade Disc in Parallels?

Is it possible to start a VM in parallels using the windows seven upgrade, and not have a previous windows OS installed?

fsck! -- pretty much covered the deal right there. The reason it's priced cheaper and is sold as an "upgrade" is under the pretense that you have previously purchased a legally licensed version of their lovely OS. If your drive is blank, you clearly aren't upgrading the version of Windows that isn't there... or you just screwed yourself by formatting the hard drive that once actually did have Windows on it.
He is also correct about there being a couple different ways to get around it, but again, EULA violation since you should "legally" as a normal everyday user buy the retail full version. Then there wouldn't be any issue. Your issue now, though, is (lucky you) as of Vista or 7, they actually started checking if you had the stuff installed. You used to be able to just simply like put an old Windows 95 CD in the drive for a second and I think that "counted" and not many questions were asked. Then people started buying OEM licenses and using them at home and taking advantage of the upgrade "loophole discount" and they (Microsoft) made it not as easy for them. That's all.

XIR3: Can Designer merge changes following a parallel development phase?

Can BO XIR3 merge designer changes in parallel development?
If I have a baseline universe ("Baseline") and then two seperate projects run concurrently (Project X and Project Y, both making changes to baseline) is it possible to then converge the changes of Project X and Project Y when it comes to releasing them?
In my scenario Project X will be released with "Baseline + Project X changes" in February, but then Project Y will need to go live in March. Project X and Project Y both start at the same time. I would like to merge "Project Y" changes into "Baseline + Project X changes" when Project Y development is complete.
Can this be done (ignoring manually making the changes all over again)?

Hi
I am afraid that the answer is no. You have to merge manually.

Free upgrade to Adobe Dreamweaver Developer Toolbox

I was sent an email stating that former ImpAKT customers will be receiving a free upgrade to Adobe Dreamweaver Developer Toolbox. I have did as the email requested and registered with Adobe. I was suppose to get some kind of a response but I have not. I then contacted Adobe by phone and was told to email ImpAKT which I have done. Still I have had no response, so now I am trying your forum. I would like to now where I am suppose to go to receive my free up grade to Adobe Dreamweaver Developer Toolbox.
Thank you for your time.
Gary

Same here. Telephone support was useless. The gal on the other end of the line didn't even know English well enough to remote understand what I was asking about. The best she could come up with was that I was "having a problem with Dreamweaver". That was after 5 minutes of trying to explain this upgrade process.
