I need to install both RTC and Rational Insight in my local machine but I am confuse that should I install Data base first for it. Even i don't know which database is right with Insight & RTC.
I don't know how to set up Dataware House?
The choice of database is important when combining RTC and Insight. With RTC by itself, especially with a small team, you can use Derby (included) for both the repository database (basically, the operational database for the product) and for the data warehouse (a separate database used for reporting). However, if you want to use Rational Insight, or RRDI (both of which include Cognos-based reporting), your must have a data warehouse on a database other than Derby. Typically, Oracle, SQL Server and DB2 are your choices, but please consult the platform requirements list for your version of Rational Insight to ensure you're using a supported configuration.
Regarding setting up the data warehouse, if you're using RTC with Insight, often you will share a warehouse between the two applications (that is, RTC can use the warehouse for its internal BIRT-based reporting, and Insight can use the warehouse for its Cognos-based reporting). In that case, you would set up the data warehouse as part of your RTC setup (the JTS setup wizard configures the data warehouse), and then point Insight at that warehouse when you set Insight up.
I hope this helps.

From my understanding, Informatica Cloud, Boomi, Talend, JitterBit are all integration tools which have "Connectors" to connect to servers (and I believe these Connectors in turn call APIs to access the required data). I saw many others but none of them are free although some are open source.
Are there any tools that help you visualize the integration process for free? If not, why not?
Tools like Informatica, Boomi provide drag and drop which show the entire flow.
Talend Open Studio is one such tool. not completely visual but almost there.
There are not many free tools as data storage technologies are constantly changing. It would be expensive for developers to keep up with constantly changing technologies without a source of income.
Developing data integration tools are resource intensive. Why would anybody(any enterprise company) spend so much of their effort and give away for free. Also the provider of the tools have to provide support for enterprise level . P1 means 4 hour response which means building the capability of the support team on par with the developer. All of these cost money and time. The only way to recoup is to sell the finished product and provide services.
I want to create table automatically using new table option in oracle SQL developer,but that option is disabled in my tool.
Can any one please help me out in this issue.
Please find the below image highlighted with red mark for your better understanding.
Thanks in advance.
To quote Jeff Smitth:
SQL Developer is built by Oracle, for Oracle. It’s the database IDE.
...
But, SQL Developer is also ... a 3rd party database migration platform.
...
Since we support migrations from these other database platforms, wouldn’t it be neat if SQL Developer could connect and query those 3rd party databases too? Surprise, surprise – that’s exactly what we DO do today.
What ‘Support’ means
You can connect to, browse, and query (SELECTs only) SQL Server, DB2, Access, MySQL, and Teradata.
What ‘Support’ does NOT mean
providing debuggers
delivering database administration features
write access to the database
Sound a little harsh or spartan? Going much further in any of these areas would just open a big ole can of worms, and we’re committed to providing an optimal experience for the Oracle database. But, since we already support these limited features, there’s no real reason to hide it.
That post is from 2012, but as far as I'm aware is still mostly true.
Since creating tables would count as write access and a DBA feature, it isn't a matter of enabling the option for your MySQL database, it isn't supported. This is an area of functionality that only applies to Oracle databases. (Even though Oracle Corp. owns MySQL... this means the Oracle RDBMS).
I am planning a large project that is going to use Neo4j as main storage to model the data, but I was wondering if I should additionally use something like MySQL as a parallel structure to back the user administration subsystem. It would have the advantage that I could use something with which I have much more experience (18 Years) to do the very tedious job of login and account administration. The disadvantage would be the overhead of keeping two databases in sync, since I do plan to have the users also represented as nodes in Neo4j with a small subset of the user information. I know that it depends a lot on the details of the project, but if anybody has experience in the field with a similar set up it would be very appreciated.
Rather than building replication, stick to your chosen database & build administration tools and UI. Replication is complex & difficult, admin tools hopefully less so.
If you can't get the data out at least in CSV for reporting, maybe reconsider choice of DB.
I am looking for some software to manage configuration data within an organisation.
The end result is to be able to answer the question "what breaks when I remove xyz component?"
We could write this ourselves but I am sure someone has done it already.
The software should answer questions such as:
- What software / systems access this data?
- Which server does this system reside on?
- What external data does this system require?
This is related to development in that to replace an existing system we must understand the interdependences and ensure that the solution does not unintentionally break other systems.
Is there a tool that shows a hierarchical tree of dependencies for a single piece of software or data repository and allows drill down?
There are a number of tools that seem to focus on hardware / OS / infrastructure configuration management using automated sniffing.
- CFEngine
- easycmdb
Any suggested CMS / CMDB?
Thank you
Yes, if you have the money, HP uCMDB is for you.
It allows you to discover hardware and processes on your infrastructure as well as the relationships between those based on TCP traffic. UNIX, Linux, Windows, z/OS, NonStop, Oracle, WebSphere, it gathers everything.
Based on the CI's collected it's possible (in uCMDB) to make models showing you those CI's you want to show plus related objects.
Also it's possible to federate/replicate external data, completing the CMS with non-discoverable items.
Afterwards it becomes possible to connect with Service Manager and roll up CMS objects into business services and processes.
I am developing a small web application,Its data size is constant.
i.e data dosent grow with date/user.
I would like to know if I can use Oracle Express for this application.
http://www.oracle.com/technology/software/htdocs/xe_lic_prod.html
Any use of the Oracle Database Express Edition is subject to the following limitations;
1. Express Edition is limited to a single instance on any server;
2. Express Edition may be installed on a multiple CPU server,
but may only be executed on one processor in any server;
3. Express Edition may only be used to support up to 4GB of user data
(not including Express Edition system data);
4. Express Edition may use up to 1 GB RAM of available memory.
So I would say, yes.
Does Oracle enforce these limits themselves? If not, how to limit the instance to run on only one CPU?
I think the limitations of Oracle are pretty deep. My experience with Oracle shows that they make money selling consultancy, and to do this they don't document their products. Expect to have a really though time if you want to do a non-default install or some fancy configuring.
Why not choose:
MySql, MS SQL Express or Postgre SQL ?
They are all free and have less limitations. If you develop your site using ASP.NET or Java or PHP all of these make sense. Postgre SQL is probably one of the strongest free database engines out there.
If you want to be really cool and flexible, use an ORM like (N)Hibernate or Linq. This will abstract the database you use, so you can easily change databases later on.
Without knowing the details of all the things you require my response will reflect that.
To name a few:
1. How many users will be connecting into this database?
2. Will it be CPU or IO bound system?
3. What DB features do you need?
Oracle Express will most likely handle your vague CURRENT needs. The issue you will most likely run into first is if your data grows beyond 4GB. I wouldn't assume your data will stay constant, few things stay constant. The pain of dealing with purging data every time you hit the 4GB data limit or having to move data to a new database is not worth the FREE marketing hook that got you to use it in the first place. If you don't plan to ever pay for an Oracle license you might be better off using an open source database such as PostgreSQL or even MySQL that won't have artificial limits placed on the software and who's license will always be free. Personally I would go with PostgreSQL.
I find Oracle Express a nice tool to get a quick install of Oracle on my laptop to learn with. I wouldn't use it for anything in production though many people probably do.
Those are my thoughts without knowing all your requirements.
And yes Oracle enforces the limitations stated previously by Thilo in the software.
