OWB Upgrade to 11g Pros and Cons

Hi,
we have our source,stage,target, databases and OWB currently on 10gR2. we are upgrading the databases to 11g. i am looking for the advantages/disadvantages of upgrading OWB also. is there a comparison document between OWB 10gR2 and OWB11g?

The major differences between OWB 10.2 and 11.1 are:
* simplified installation
* new option for connecting to Siebel
* new option for integrating OWB with Oracle MDM
* bug fixes
Unless you need any of the new options or bug fixes, I'd recommend sticking with OWB 10.2 on Oracle 11.1. We have numerous customers doing this. And, when OWB 11.2 comes out, you will be able to directly upgrade to it from OWB 10.2.
More info regarding new features at http://download.oracle.com/docs/cd/B28359_01/owb.111/b31278/whatsnew.htm#CHDIBHGJ

Oracle 11g Pros and Cons

Hi Experts,
We are planning to upgrade oracle from 10.2.0.2 to 11g, could any one please let us know the pros and cons of 11g over 10g
Thanks,
Ravi

Sure:
PRO: it's the only Oracle version currenly in general support.
PRO: it provides many new features, e.g. compression for tables, indexes, backups
CONTRA: it means you have to learn new stuff and implement something you're not used to.
Generally, the support argument just makes other considerations superflous.
As a SAP customer you basically have to follow the upgrade plans.
regards,
Lars

IntelliJ IDEA 7 vs JDeveloper 11g Pros and Cons

Here is a thread we can discuss what we like or dislike as a comparision between IDEA 7 and JDeveloper.
Surya De mentioned in the other thread that IDEA has exceptionally strong code editing and code analysis features. In my experience I don't find IDEA's code analysis any more useful than JDeveloper's. And it's details about the code editing that I like in JDeveloper and dislike in IDEA.
Some of the details I find annoying in IDEA:
Code Folding - IDEA seems to unfold when I don't want it to; IDEA requires a multi-step menu choice whereas in JDeveloper I just right click on the folding area and select the option I want.
Java Doc generate - I prefer the way JDeveloper lets me generate the JavaDoc stub for a method.
Light bulb - I'm not sure how to describe it but in IDEA a statement may be underlined and flagged as wrong or might have an option to change it or improve it, in JDeveloper there is a nice simple light bulb I can click on to access these choices, in IDEA that "light bulb" seems to be very elusive and I can't figure out how to get it to stay there so I can click on it (most of the time I end up just manually putting in the code rather than using JDeveloper's wonderful assistance).
In what way is IDEA's Ctrl+N different from JDeveloper's Ctrl+-? They both work equivalently as far as I can see (JDeveloper is a little too aggressive in trying to guess what class you wanted)
IDEA forces me to manually set the run target instead of intelligently trying to run the class I am working on. This could be a pro or a con, but I'm used to JDeveloper's style and thus I always catch myself running the wrong thing in IDEA.
IDEA is slow compared to JDeveloper.
IDEA is terrible for building a standard client application JAR file (JDeveloper does this very nicely with it's deploy profiles).
IDEA lacks "status icons" for version control, I find the slight color change of file names to be inferior.
IDEA's non-standard usage of the term "project" is confusing.
IDEA lacks the nice little "X" close icon for closing a file you are editing.
"History" comparison I find nicer in JDeveloper.
In IDEA if I have folded code I have to hover over the code itself (making for a lot of mouse movement) to quickly view the folded code (without unfolding it), in JDeveloper I can just run my mouse up and down the left edge where the fold icons are.

Code Folding - Simple you can set it up in the Settings -> Editor -> Appearance tab an select which ones to collapse by default. All you do is mouse over the folded area in the editor and it will show you without expanding, the contents inside it...until you click that then it will explode the folded area.
Javadoc generation - Never tried it. But writing comments is easy and you dont need to know any syntax since it gives you suggestions. You will see them in yellow or red in the error stripe bar on the right just like Jdeveloper.
Light bulb - Intellij has light bults also and its context sensitive. Sometimes if you write bad code it will highlight and make it show as yellow on the stripe bar on the right and if you click then you will see a light bult on the left with a suggestion to rewrite the code and it rewrites the code for you. You can set a profile as to what the editor should look for in terms of non-optimal coding. A quick example is if you have code like (Long[]) zoneIds.toArray(new Long[0]) Intellij would rewrite it as (Long[]) zoneIds.toArray(new Long[zoneIds.size()]) and give an explanation about how the previous would be using reflection and how this one would not. This is just a small example. There are literally 100s of settings for the code analysis tool.
Speed - I dont see any difference. I am running Intellij on Mustang the latest build. And so is my JDeveloper at home.
As for the other stuff you mentioned with the project and jar file etc I dont bother because we are using Ant. I can set up the ant build file into Intellij and just right click on the target I want. But most of all I like using command line better.
IDEA does lack the little x close icon on the tab for the file you are editing but seriously hit Ctrl F4 or just middle click. Thats a bit ridiculous for mentioning that.
Local History/ CVS History - I do like JDevelopers a bit better. But Intellij has more details. As in if you fired up debug mode and made some changes in your code it will mention that as an event in your local history and that makes it easier which JDeveloper doe not have.
'In IDEA if I have folded code I have to hover over the code itself (making for a lot of mouse movement) to quickly view the folded code (without unfolding it), in JDeveloper I can just run my mouse up and down the left edge where the fold icons are. '
Dont even know how to reply to that...I dont count mouse movement as one of my criteria...
You can right click on a file in Intellij, hit Analyze code and it will show you a list of things in the code that can be cleaned up/fixed/etc based on profiles you select. They can be anything from performance fixes to too complex if statements. Pretty much as if you are doing code review. There are tons of options. And you can see all the items that Intellij is suggesting to fix, right click and just Apply Fix and they all get cleaned up in one shot. You can do this to your modules as well.
DSM - Go to Intellij's website and look this one up. Really useful for analyzing your overall codebase and finding circular dependencies etc etc.
Also the code completion in the editor in Intellij is a lot smarter. I can use Ctrl Space for the regular thing that JDeveloper does. But Ctrl SHift Space does smart code completion which I find extremely useful when writing stuff like say...uh...SomeObject obj = new SomeObject(). I can just type SomeObject obj = n and hit Ctrl Shift Space and it will write the rest of of it for me. Also if the constructor requires some parameters and you have those parameters initialized it smartly sticks those in there for me.
Also when you are naming objects or variables with Ctrl Space it can put a Java Coding Convention compliant name for your object or variable so you dont have to think of one and its pretty cool. A lot of nifty little things in there.
Lets see Alt Insert shorcut is awesome for constructor, getter/setter generation and a few others.
Also Ctrl J is an awesome feature to have where there are code templates already in place and you can just have boiler plate code for iterating over array, writing for loops etc so you just select what you want and based on what variables are in place it will automatically write your loop structures, your try catch blocks etc for you.
Also Ctrl H is another feature I like that shows in a window on the side the hierarchy of the class you are looking at.
Theres lots of little gems in there that I cant thing of writing about right now.
I still dont understand 'IDEA's non-standard usage of the term "project" is confusing.' If that is a complaint it seems you are reaching!
Like I said. Intellij is superior in terms of usability with keyboard and its editor and code analysis. You dont need findbugs or PMD for that. Its better actually than them.
But thats it. I think JDeveloper in terms of the wizards and all that I like that. Thats why I use JDeveloper when using SOA, or doing quick prototyping. And it works seamlessly if you have a full Oracle stack. But if you are using Apache or other web servers Intellij makes it easy since you jsut configure the server in your IDE and it does the rest.
Also it comes with Hibernate, Spring, support and now Flex (Intellij 8) out of the box. Thats pretty cool. Very useful.

Upgrade Service Pack (pros and cons)

Hi,
We need to upgrade the PI 7.0 from SP16 to SP17, could you please guide with the positive & negative aspects of it.
Regards
Prathibha

Hi,
Upgrading Service pack in PI environment is a common task,
The new service pack always offers some new benefits like (SAP solves some bugs in current version SP), so chance of getting bug/error will be less. Some times it offers new features.
Negatives some times java mapping programs, if you used any external jar files, it may create some problems (few times).

Pros and Cons af Oracle 10g upgrade to 11g

Hi Basis Expert,
We have an requirement of SAP upgrade which includes BW 3.5, CRM and R/3 (4.7).
These components needs to be upgraded to the latest version
BW 3.5 to BI 7.0
R/3 (4.7) to ECC 6.0
and also CRM upgrade to the new version
The OS used is AIX and DB used is oracle 10g.
Can anybody share the pros and cons of oracle DB upgrade from 10g to 11g after SAP upgrade.
Regards,
Anil.

Hi DatabaseSAP and others,
Thanks for your reply
I started with the Oracle 11g software installer. But it gave an error during 71%. Error is

11g upgrade pros and cons

Folks,
If there's already a similar thread, apologies in advance.
I wanted to gather some information on the pros and cons of upgrading to 11g from 9i and from 10g (Enterprise Editio) rdbms on Solaris.
What are the challenges you have faced (especially if you have tweak SQLs/optimizer etc.) post upgrade?
Any issues DURING the upgrade?
If I missed anything obvious that worth bringing up, please do so.
Thanks for your time!
Regards..

Pros/cons depends on the database type and activities ( no. of user/ data/ transaction etc).
but i would suggest upgrade your database (9i is history).
you will get many new features in database which are not available in 9i.
1. upgrade on test server
2. check the performance
3. everything goes well
4. upgrade on live server

Too worried to upgrade software. The pros and cons

From a NOkia lover to others,
I am all for making improvements and fully understand that we can't always get it right first time every time but atm I am too concerned with the fact that updating my software will create problems that are non-existent in my eyes.
My girlfriend updated her (my old) N70 software last week and now her phone is in the repair shop. This could just be a coincidence but....
I had an N95 (on orange) and was stung when the "unlucky for some" version 13 was installed on the handset. See the epic thread here "N95 firmware upgrade affects battery life" (couldn't post link)
I carried out the full back up to my card as instructed but the games I purchased would no longer work so had to re-buy them. The battery life was killed in eight hours due to the wlan making a connection attempt as long as the battery would allow it to happen. The point is... all of this was not happening before the update.
It was that bad that in the end I was forced to upgrade / get a new contract before I was entitled to one from Orange and had to fork out for two contracts to get the handset spec I needed.
I now have an N95 8GB and have no qualms with it what so ever. It has version 20 atm and pc suite informs me there is an update every time I boot the program up. So far.. I have declined to update.
So what are the pros and cons and is it more of a risk to chance losing the licenses I have paid for and update if nothing is wrong?
Best Regards
SgtTrojan
The swordsman that goes to war thinking of saving himself had better not go to war at all.

I myself am also worried. A friend of mine told me if there is no porblem with your current version of firmware for your phone then why update? It is not a assurance that after updating there would be no problems/bugs with the new version.My friend has a point. Why would we update if there is no problem with your current firmware version? Some would say it would be faster, there would be more improvements to the music ( which I know would be depending with your hardware and not the software).
I am thinking of updating my firmware with a Nokia Service Center here in my country (Philippines). It is for free at the moment because my phone ins under 1 year Warranty. But I am thinking twice after what my friend told me.
I hope my opinion helps you all out here.

Pros and Cons of upgrading GT60 RAID0 to SSD and HDD

I purchased a GT60-0NCR-002US from Amazon last fall and am thinking of upgrading the HD set up.
Currently it has 2 500gb drives arranged in a RAID0.
I'm considering upgrading this to a 256GB SSD and a 1TB HDD and am curious to get some feedback about the pros and cons of doing this.
I'm assuming this setup would be considerably faster than the current one since I'd have the OS and all program files on the SSD. I'm not sure whether the 7200rpm 32gb cache HDD would be faster or slower than the current RAID0 but since this would only contain my documents and media, I don't think it's of that much concern.
Another question I have is how I'd go about getting Windows back on the system after replacing the hard drives. Could I reinstall an image of the current OS or would the fact that I'm changing the hard drive set up make that impossible?
Any advice would be appreciated.

Quote from: joshsayers on 23-May-13, 09:18:47
I just noticed on the original Amazon page where I bought the computer that the rpm of each 500GB disk is 7200. Considering they are in a RAID0 format, wouldn't I then be sacrificing speed going to one 1TB 7200rpm drive?
Maybe the decrease in speed for the data/media HDD would be more than compensated by having the OS and all software run off an SSD drive, though...
Regarding the re-installation of Windows: yes, I have the backup disk here. So it would just be a matter of re-installing on the SSD drive before the regular HD was installed? I called MSI help and asked them about this and the guy told me that because I would be going from RAID0 to two separate HDDs that this would affect the BIOS and thus the original Windows backup disk would be obsolete. Any truth to this?
The SSD + HDD will be much better overall. For media, does it really MATTER how fast it is? In all honesty, not really. The SSD makes everything else snappy, so what if you have to wait an extra 10 seconds when you copy a movie over and stuff? I wouldn't care, overall the laptop will FEEL much faster, and it generally will be.
There is SOME truth to what he said. You will have to change the bios to go from a RAID to AHCI or IDE (AHCI is preferred, but it may not work....I'm not sure). THAT much is true. The restore disk should work as usual though. It doesn't care WHERE it gets installed at, just that it gets installed. Atleast, it didn't matter for me.

Pros and cons of Quad Ram upgrade

Hi everyone -
I've checked the PPC G5 Memory Specs and Requirements for a Quad.
What are the pros and cons of installing a 4GB ram upgrade (if I'm going to upgrade why not get a lot, I plan to use all of the available slots)? Are there any brands to watch out for or avoid?
Thanks in advance for your responses.

Hi-
Pros are better peformance and ability to maintain more open applications. Current prices are lowest in history.
Cons, none that I can think of.
+Avoid any memory that isn't specifically guaranteed to be Mac compatible.+
*Your spec is PC2-4200 (DDR2-533) 240-pin SDRAM DIMMS.
*The RAM expansion slots accept 240-pin DDR2 SDRAM DIMMs that are 1.8 volt, unbuffered, 8-byte, ECC and non-ECC, and DDR2 533 MHz (PC2-4200) compliant.
*Additional DIMMs must be installed in the bank slots in pairs of the same size and type; ECC and non-ECC cannot be paired in a single bank.

Hi all,
1.What are the pros and cons of installing java+abap stack for portal?
2.what effect it does on the ume options to be choosen??
3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
regards
Rajendra

Hi Rajendra,
The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
In a nutshell:
ABAP+JAVA
Pros
- Decrease # of servers required to administer the portal
- Less costly
Cons
- Upgrades could be dependent on ABAP and Java release level
- Additional load on the server due to ABAP stack
- Limited scalability
JAVA and ABAP on separate server
Pros
- Improved performance
- Allows each system to be single-use purpose therefore downtime does not affect other components
- More scalable
Cons
- Adds complexity to landscape
- Additional costs

What are the pros and cons re using an intel iMac vs MacPro with LP8?

I'm considering getting a new intel Mac in the near future (presuming a new MacPro will be released in the near future - maybe at the same time as Leopard). I compose largely for film and television and I am composing largely using a combination of loops, software instruments and some recorded live performance. I usually sync to a low res quicktime movie.
I do like the idea of a simple and uncluttered work environment with an iMac, added to which there's also a degree of portability with the iMac however the MacPro is obviously more powerful. I'm not sure how much the difference in power between the two computers would affect me.
Would I be compromising myself much if I went for the iMac over the MacPro? What are the pros and cons of the iMac vs the MacPro in relation to Logic Pro 8?

In the world large-scale music composition using samples, loops, etc (especially for film) your two biggest needs are RAM and HD speed/access. The imac looses big time in this department (as a single computer at least) as it can only be upgraded to 4gb ram, and only holds one internal HD, and also lacks any PCI expansion for DSP cards, audio interfaces, etc.
In generalyou want to separate your data vs applications as much as possible, to ensure both can be accessed quickly and easily by the computer. So its best to have your system software / applications on one internal HD, and your logic data (samples, audio recordings, loops) on another drive(s). You can do this with an iMac via USB, FW800, & FW400, but depending on how big your projects get, how many USB and FW drives / interfaces you use, and how much data you need to stream, you could overload the buss on the imac (not sure if it has multiple busses or not). Plus speed wise, internal SATA are much faster than external drives, and the mac pro with its 4 internal slots seems like a great choice for speed and flexibility.
However, if you dont find yourself doing large scale projects, then you might be better off going with an imac. We just purchased one for my father and it runs great! It blows the socks off of my Dual 2.5 G5 tower in terms of CPU speed! If you run into problems running things from the imac, you could always add a mac-mini down the road to stream sample libs, as a Logic node, etc, which seems to be a much more cost effective solution.
I hope this was helpful, but I probably just made the decision harder . In fact, if I were to start over today, I dont know if I'd go with a MacPro, or an iMac / mac mini combination. they both seem to have their advantages / disadvantages.
Best of luck!

Pros and Cons of putting jspx pages under WEB-INF

Greetings All,
I have been using JHeadstart release 10.1.3 Prod for a while now and was generating pages in various subdirectories under WEB-INF/pages/ and things are working fine.
However, recently I came across a post in jDeveloper forum Re: Access JSF Pages within WEB-INF directory where Frank Nimphius has mentioned that there is no sense in putting JSP files that are used with JSF into WEB-INF.
I know that in struts world it makes sense to put the jsp files under WEB-INF to prevent the users from directly accessing them and force them to access them only via struts actions/navigation rules; but in JSF world we anyway expose the jspx names to the user and in-fact if we keep the pages under WEB-INF the url to access the pages also contains 'faces/WEB-INF/...'
Thus, I would like to get opinion from various experienced professionals participating in this forum and more so from JHeadStart team members on Pros and Cons of putting jspx pages under WEB-INF
regards - rutwik

Rutwik,
From your reply it seems that, for now, there should not be any impact on us as long as we don't upgrade to JDeveloper 10.1.3.1, as anyway the current JHS version is not certified against it.
Correct.
However, to be compatible with future releases of JHS and JDeveloper, will it be good to change the location of pages in our JHeadStart definitions to move them a directories above the WEB-INF etc and re-run the JHeadStart generators?
Yes.
Or, will the patch take care of modifying the current JHeadStart definations?
No, Service Update 1 has a different default value for the pages dir , it is now /pages/ instead of /WEB-INF/page/, that's all.
Also, with this patch, will we be able to upgrade to jDeveloper 10.1.3.1, which we would like to do once we have a production release?
Yes, Service Update 1 is compatible with JDev 10.1.3.1

Using CLOB data type - Pros and Cons

Dear Gurus,
We are designing a database that will be receiving comments from external data source. These comments are stored as CLOB in the external database. We found that only 1% of incoming data will be larger than 4000 characters and are now evaluating the Pros and Cons of storing only 4000 characters of incoming comments in VARCHAR2 data type or using CLOB data type.
Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;
- bind variables cannot be assigned CLOB value;
- dynamic SQL cannot use CLOBs;
- temp tables don't work very well with CLOBs;
- fuzzy logic search on CLOBs is ineffective;
- not all ODBC drivers support Oracle CLOBs
- UNION, MINUS, INTERSECT don't work with CLOBs
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?

Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;They can be stored inline too. Depends on requirements.
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;Toad is a developer tool so that shouldn't matter. What should matter is how you display the data to end users etc. but that will depend on the interface. Some can handle CLOBs and others not. Again, it depends on the requirements.
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;Why would they struggle? 18,000 characters is only around 18k in file size, that's not that big to a web page.
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;Who's caching them in memory? What are you planning on doing with these CLOBs? There's no real reason they should impact performance any more than anything else, but it depends on your requirements as to how you plan to use them.
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;You can manipulate CLOBs in SQL too, using the DBMS_LOB package.
- bind variables cannot be assigned CLOB value;Are you sure?
- dynamic SQL cannot use CLOBs;Yes it can. 11g supports CLOBs for EXECUTE IMMEDIATE statements and pre 11g you can use the DBMS_SQL package with CLOB's split into a VARCHAR2S structure.
- temp tables don't work very well with CLOBs;What do you mean "don't work well"?
- fuzzy logic search on CLOBs is ineffective;Seems like you're pulling information from various sources without context. Again, it depends on your requirements as to how you are going to use the CLOB's
- not all ODBC drivers support Oracle CLOBs not all, but there are some. Again, it depends what you want to achieve.
- UNION, MINUS, INTERSECT don't work with CLOBsTrue.
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?You may have more hassle if you "need" to accept more than 4000 characters and you are splitting it into seperate columns or rows, when a CLOB would do it easily.
It seems as though you are trying to find all the negative aspects of CLOBs and ignoring all the positive aspects, and also ignoring the negative aspects of not using CLOB's.
Without context you're assumptions are just that, assumptions, so nobody can tell you if it will be right or wrong to use them. CLOB's do have their uses, just as XMLTYPE's have their uses etc. If you're using them for the right reasons then great, but if you're ignoring them for the wrong reasons then you'll suffer.

What are the pros and cons of running iTunes from an SD card with a Retina MBP?

Hello,
I'm thinking about getting a Retina MBP, but I think the default storage of 256GB is way to small to be used as a main computer and the upgrade to 512GB is very expensive. I was thinking of ways to reduce bulky files and was considering running iTunes from an SD card. Does anybody have any experience with doing this, what pros and cons did you discover?

I wouldn't even try storing multiple iTunes libraries on SD cards. Better idea - what I do - is store the majority of my music on an external hard drive and just my 'must have' tunes on my internal SSD. I have a 512GB SSD and use around 170GB for iTunes. On my external drive, I had about 440GB in tunes (last time I checked).
You can 'switch' libraries by holding down the option key when you launch iTunes. It's the best of both worlds - storage for on-the-go, must-haves, and an entire library of "all" of my music.
256GB should be plenty of space - I just store so much music on my internal SSD because I can!

Pros and Cons to Jobs vs Positions

I have a client with 120Employees.
They have plans to grow to 600 and cap at 800.
Every year they go before a Board to request for budget and approval for FTE and Jobs or positions new positions.
Each position has a budget tied to it
What are the pros and con for budgeting on the job level versus the position level?
What functionality will be lost if i go with budgeting at the job?
