Multiple projects on a single BI environment

Hi,
We are using for our project a BI environment that is already used by 2 projects.
For sure, I need now a datasource (re vendor survey flow) that is already in use by another project (I want to use the BC flow already used 'as is' by the project).
I replicated the DS from my source system to BI. Now, in BI, I can see the same flow (from DS to cube) for my source system and their source system.
1 - if I load master data and transactional data from my system using this flow; what would be the impacts on <u>their</u> flow? They should be impacted and values overwritten. Correct?
2 - what are the options of sharing the same DS (same object names) with different projects?
3 - Do we have any solutions of "mass renaming" during object copy??
Thanks for your insights.

Hi Chris,
normally you need to make sure that your master data is unique in all systems --> that means loading a vendor from system a with no. 0815 is Mr. Smith in 5th Avenue No. 5 in 99999 Somewhere is exactly the same coming from system b ... If you cannot ensure that a vendor with no. 0815 is the same you need to somehow harmonize the data or make it possible to identify them coming from different systems --> check this: https://websmp105.sap-ag.de/~form/handler?_APP=01100107900000000342&_EVENT=REDIR&_NNUM=184948&_NLANG=EN
For your transactional data it is a lot easier. Here you can just add 0logsys or 0soursystem as a characteristic to your cube, fill it from the update rules and you can separate the data by filtering on that object in the query or having different authorizations on that objects.
But anyway, getting the master data updated correctly is the toughest part in that project and there is not only one solution.
kind regards

How to compile multiple RH projects in a single go ?

I have more than 100 Projects to be compiled. Is there any option in RH 8 to compile multiple projects in a single go.
Please Help .
Thanks
Neeraj Malik

Welcome to our community Neeroj
If all the projects are simply variants of a single project you open in RoboHelp, you could use the Batch Generate feature. But I'm very doubtful that's the case here.
I suppose you might investigate using the command line compile feature. Perhaps you could accomplish it that way.
Click this link to read about Command Line opertations
Or crack open the help system for RoboHelp and look at what it says about Command Line compiling.

Issues with multiple Files with multiple subdbs on a single environment.

I'm having an issue with Berkeley DB 4.2 on 32-bit platforms, regarding multiple physical files with multiple subdatabases in a single database environment. Specifically, when I open a subdatabase for a physical file, Berkeley DB thinks that it is using the same subdatabase in a different physical file.
I'm doing the following:
1. Create and open a db enviornment.
2. Move file1 to the common area.
3. Open, get and close the subdatabases in file1.
4. Move file2 to the common area.
5. Open, get and close the subdatabases in file2.
6. remove file2 from the common area
7. Move file3 to the common area.
8. Open a subdatabase from file3. About 1/2 the time, the fetches
return data from file2, not from file3.
It's possible that at some earlier time (i.e. before step 1 of this
test case), file1, file2 and file3 were the same file. I noticed
that there is something called env->fileid_reset, but that is not
in 4.2.52.
Any ideas?

Looks like I've resolved the issue

The Apple Configurator tool robbed my school of @ 60×4 apps.
Here's my mistake. I bought all the apps needed for the whole school in one lump sum. i.e. 350 copies of Pages. Then happily went to Configurator and loaded the spreadsheet. Installed on all the student iPads. Then need the remaining licenses to gift to the teachers and @ 30 for the cart. NOPE! Once they are loaded in to Configurator you can never get them back. Apple said, “sorry”.
I did this for the iWorks suite, iPhoto, & neu.Annotate before I realized what was happening.
This is what to do, in short. From the VPP account, buy the number needed for exactly what you need, just make sure, it's over 20, even if you only need 11, 20 copies is cheaper than 11 because they are half off at 20 or more. Get the spreadsheet generated by the VPP site for the 20 then buy for the next cart or site, it will generate a new spreadsheet of 20 you can give to the computer and its copy of Configurator.

Multiple Applications in a single Project

I currently have a Flex project that has multiple Applications created within it.
The first application opens the second application via code as follows:
var str:String="event_home.html";
var link:URLRequest = new URLRequest(str);
var v_selectedEventIDCode:String;
this globalEventId = dg_event_listing.selectedItem.ID;
navigateToURL( link, "_blank" );
My 1st question is, can the 2nd application that I open grab values of variables declared
within the application that opened it?
2nd question is, if I have a project with only 1 application defined within it, how can I
open a 2nd Internet Explorer window with some other Flex page in my project without creating a 2nd
application in this project? for example I may have a single Application in this project, and then another
file in this project that is a Canvas component, the app starts up with the Application page, how do I open
a 2nd Internet Explorer page with that Canvas component within it?
Thanks in advance,
Wes

> Is it possible to package multiple applications into a single .air file?
No, Flash Builder (and AIR) does not support that.

Need help to create a login for maintenance of a single database in a multiple databases, single instance environment

Hi,
We are in the process of consolidating several databases on a single instance of SQL Server 2012.
Databases are developed by outside vendors; they have to be able to install and support their databases but they shouldn't be able to do any thing with the other databases.
When I tried to migrate the first database, the vendor told me that on the former server he used the sa account in some batch.
On a previous thread
https://social.technet.microsoft.com/Forums/sqlserver/en-US/dc1f802f-d8de-4e2b-87e5-ccb289593fb7/security-for-multiple-applications-on-a-single-sql-server-2012-instance?forum=sqlsecurity
it was suggested to me that I create a login for each vendor and that this login should map a user in their respective databases.
To test, I simulated the process in a test database:
1 - I create the login and I scripted the command:
USE [master]
GO
/* For security reasons the login is created disabled and with a random password. */
/****** Object: Login [M02_Test] Script Date: 2014-12-02 16:23:58 ******/
CREATE LOGIN [M02_Test] WITH PASSWORD=N'ÈS^y¡¶=Å€"+y¤j|úªhÖféÎÐ•œEu
c', DEFAULT_DATABASE=[M02], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO
ALTER LOGIN [M02_Test] DISABLE
GO
2 - I create the user and scripted it
USE [M02]
GO
/****** Object: User [M02_Test] Script Date: 2014-12-02 16:29:41 ******/
CREATE USER [M02_Test] FOR LOGIN [M02_Test] WITH DEFAULT_SCHEMA=[dbo]
GO
Questions:
What should we do with te scrambled password: is it saved as it was entered and should it be kept somewhere in a safe place?
Would that do the job for the vendor who used sa before?
Thanks for your advice

I'm not sure why you would save the script. Why not create the login, in one way or another give the vendor the password. Keep the login disabled until needed.
I don't recall exactly what we said last time, but it occurs to me that the application setup things on server level. Jobs is the prime thing that comes to mind, but there could be other things.
Now, here is an important observation. As long as the vendor's application was alone on the server, that was OK, and it was OK to give the vendor sysadmin rights. In this situation this is less OK, and as we said, you should only give the vendor db_owner
in the database.
But the vendor will need to tell you what they do on server-level. They should know this - unless they sell their app as a "alone-on-a-server application". (And there are indeed such applications out there, even from Microsoft.) But there is a
risk that they will bill you extra if you make their installation more difficult.
Maybe you will have to give some vendors sysadmin for the installation, but in such case, you should ask them why they need it. If they don't, give them db_owner, and they will have to find out their hard way. (And you don't pay them for learning
their own application.)

Multiple BPEL Process Managers in one environment?

Hi,
I'm quite new to the Oracle SOA product line, so please be gentle when my question doesn't make sense.
I’m in the process of designing a new enterprise architecture based on service orientation. I’m looking at the Oracle SOA Suite software to get a better understanding of what things will look like when getting to the actual implementation.
Some internal projects are moving fast, so I’m trying to get an understanding on how things will work out in the future. One case has my current attention, related to the BPEL Process Manager.
A 3rd party vender is offering a specific solution which is using or based on the BPEL Process Manager. This solution can be purchased as a black-box. From the perspective of my new architecture I would like to purchase the SOA suite as a whole. New developments will most likely be using the BPEL Process Manager for orchestration. But when purchasing the black-box application, the environment will be extended with an extra BPEL Process Manager. My first thought is to try and incorporate the BPEL processes from the 3rd party vendor onto one single BPEL Process Manager. But I also think two BPEL Process Managers can have advantages.
I’m not sure how to go forward with this. How should I handle this? Is it common to have multiple BPEL Process Managers in one environment or should I pursue maximum integration and only go for one BPEL Process Manager?

Hi,
We have similar situation at my current client site and we are going with two seperate BPEL PM installs for various reasons. One of the main driver in our case is conflicting in timelines of two seperate projects.
But my suggestion is to go with single enterprise install if that's not breaking the 3rd-party vendor supporting contracts. This has obviously benefits of redecued infrastructure/administrative and other related costs. How many processes does the vendor has as part of their solution? If they are handful you know it doesn't justify having seperate environments.
On the otherhand having two seperate installs isn't bad either depending on how big or small your SOA service/process orchestration footprint is. We don't have complete handle on the performance/scalability aspects of BPEL PM based on number of processes deployed. But as you can see that may be one of drivers to have redundancy in BPEL PM servers.
End of the day there is no clear cut answer. If you have funding and resources, go with two seperate instances. But from architectural perspective better to have single install with clustering for better performance/scalability.

Multiple projects and their promotion from Develop to Test to Production

A customer has an interConnect infrastructure running about 5 projects. Each project has a Development, a Test, an Acceptance and a Production environment.
This basically works, but is really cumbersome to maintain.
They want to reduce the number of Interconnect installations as much as possible to ease maintenance. The iConnect version is 10gR1.
As far as I can see there are two options:
1) Put all projects into a single repository. You'd end up with only 4 InterConnect environments (Development, Test, Acceptance and Production)
2) Put all hub schemas into a single DB
The first one is obviously our favourite, but can you promote a single project to a new environment (say, from Development to Test) without affecting the other projects in the same repository? How difficult (if possible) is this? What are the possibilities and risks?
What are the possibilities for option number 2?
I hope anybody can give me some advice.
Arjan

Its slightly confusing about having multiple projects, the reason being the way Interconnect works is that it has a single database repository and when you create a project it is just a view on that repository. Therefore a project and a repository are essentially one and the same.
Therefore it would imply that if you have 5 separate projects then you also have 5 separate repository instances.
In terms of your options:
1) is the general way that most projects work. Lets say you have DEV, SYS, UAT, PROD. Therefore you'd generally have a repository instance for each env, therefore 4 repository instances, HUBDEV - for DEV env, HUBSYS for SYS env etc... These repositories would usually be in separate Oracle Instances although they could be on the same servers. Therefore the Hub schema for all, would be the normal one installed by the product, OAIHUB904. Then you would also have a single project for each repository. This repository would hold all the metadata for all your interfaces that go though this HUB instance.
As interfaces move through the various phases then you migrate between the different repositories, to move stuff from DEV to SYS etc...
2) From my understanding, this is not much differnet to the above except you want to hold all the Hub schemas in a single database instance. This is possible by creating each schema with a differnet name, OAIHUB904DEV, OAIHUB904SYS etc... and you would need to change the necessary infrastructure ini files to use these new names. With this setup you would still have 1 project per repository but it would just point to the relevant schema.
Let me know if you have any more queries.

Stuart.

How to manage multiple resources in multiple project?

Hello,
We are a very small company that has migrated from an in-house TFS solution to using VSO to manage our projects. One issue we are having is being able to look at outstanding tasks and resources allocated across multiple projects. What I'm looking
for is one place where I can see how many hours a person is allocated for a given week for all projects.
Thank you for your help!
Curt

Hi Curtis,
You can create a single team project and create teams for each of you project. Then you would be able to monitor all team progress etc using root team project and each team progress can be separately monitor. If you use parallel iterations across all teams
this would be more effective.
For team capacity you can set full capacity to root level and divided capacity levels to each team.
Scaled Agile Framework is explaining similar concept here for more complex situations in below article. But you can use a simplified version of it.

Multiple databases in a single query

I need to query multiple databases in a single query.
e.g.
Database d1 contains table t1 with column id
Database d2 contains table t2 with column id
I need a query like
SELECT * FROM t1, t2 WHERE t1.id = t2.id;
is this possible in jdbc? if yes can anyone help with some sample code?
thanks,
Ashish Saraf

It is not possible using the JDBC API to query tables in two or more databases using a single query. The reason is that a JDBC Connection is made to a single data source.
However, some databases support the idea of federations or linked tables. What you do is inside the database manager link or federate a table that is present in another DBMS. Then, pose a single JDBC query to the one DBMS which will have its own table and links to the external tables.
Another approach is to use a special JDBC driver with a built-in integration engine that will perform a query across multiple databases. In effect, the system poses separate queries to the different databases and integrates and joins the data together for you automatically on the client-side. That is much easier than doing it yourself in code, but that is also possible for simple queries.
As part of my research program, we have released a shareware version of the UnityJDBC driver that can query multiple databases using a single SQL query. For more information, see:

Multiple OUs using a single common WIP?

Multiple OUs using a single common WIP?
We have a manufacturing facility that contains tools and personnel that belong to multiple operating units (OU). Of course, the manufacturing part should work as if it is one site. Since all equipment and personnel work on all jobs there is no distinction between the higher level operating units and legal entities and books at the low level manufacturing point of view. However, costing must be costed appropriately by OU and the GL books of the seperate legal entities must be kept correctly and seperately.
How can Oracle Applications manufacturing modules be setup to handle a common manufacturing area used by personnel and equipment that is owned and costed by seperate OUs? I am unable to locate an example or reference to this type of situation in any manufacturing manuals.
Thanks

Not sure that you will be able to find your example. You explain an interesting problem that is very unique. I do not think that you will find a standard system set up to meet your need. The work around solutions, that come to mind quickly, would require a standard cost environment and involve changing the period close process for manufacturing.

Multiple iPads on a single account?

I am a school teacher, and my principal asked me if I wanted to use iPads for a small group of students to try creating a class with alternate assignments and activities. I would like to, but how do I get multiple iPads on a single account so they can be preloaded with apps, and students can't add or remove apps?
Or, and even better scenario would be that there is a main setting with certain apps that are added and cannot be changed by the individual students, but they could create a sub-account that they could use with their own iTunes account while they have use of the iPad. When they are done with it, and we use it for a different student, it would be good to be able to wipe out the sub accounts and still have them set to the school's requirements.
Any way that is possible? If not, there is no way I would use the iPad for a class. I need to be able to control what they have at a basic level, but I don't want them tied to my personal iTunes either.

Visit the iPad Educators Ning or the EdTech listserv to talk to teachers who are using the iPad in the classroom. As VT said you can't create sub-accounts or limit their controls in the manner you're describing, but you may find other options.
The real question is what kind of "alternate assignments and activities" are you planning? Ones that require or take advantage of the unique form factor of the iPad? Ones that require apps? Or ones that can be done on a laptop/desktop computer just as easily? The project should drive the equipment, ideally, not the other way around - although I do understand that when trying out a new tool one wants to look for scenarios to use it. :-)

How to add multiple databases for a single frontend

We have a project based on distributed databases and we have to workout on .Net framework.I want to know some information of connecting multiple databases for a single frontend and how can we access them.
If so we have connected 2 databases for a single frontend in future if I want add one more database to it how it will be possible to do it without disturbing the current connectivity.
Please help me in resolving this problem.
Thanks......

hi,
what do you mean by connecting 2 databases? can you explain further?
using entityframework you can connect to different databases
public class CustomerContext : DbContext
public ReportContext()
: base("DefaultConnection")
public DbSet<Customers> Customers { get; set; }
and your connectionstring (config file)
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=D:\\Database\Project.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
you can add more connection strings on it.
