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.

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.

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

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

Pros and cons of using email sending package in oracle 8.1.6

hi ,
i would like to know the advantages /disadvantages of using email sending package from oracle 8.1.6
compared to sending the same using say perl or php.
iam developing a site in php/oracle8.1.6 , in which iam supposed to create a payement module.whenever a user
register(for free trial or subscribing the site) i'll have to send him a welcoming mail.In addition to this iam also supposed to find out wether subscribers are paying cash at right time and if not send them reminder mails and other for related scenarios . i can do the same in Perl or PHP.but if iam not gaining much(say based on server performance or load) then i think i can go ahead with oracle package. when i tested it i found that its slow . what about the load that it may cause for the server (ours is linux ).
please do give inputs on this

Hi Ravi,
Thanks for your reply.
But I am specifically looking at pros and cons for web services. So the thread which you passed to me won't help.

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

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.

Oracle 11G database and Application Server installed on same server

What are the pros and cons installing Oracle 11G database and Oracle Application Server (Forms and Reports) on the same server?
Thank you in advance, Sonya

Some may want their data in a separate network zone for security reasons.
It also depends if it is the same people that do maintenance on db and appserver.
It is lower cost with one server, and only 1 Os to set up.

What are the pros and cons using Active Data Guard vs Data Guard?

My understanding is that Active Data Guard is an additional database option for Oracle 11gR2 Enterprise Edition. I need to know the pros and cons using Active Data Guard vs Data Guard in order to decide whether to get pay extra for the Active Data Guard.
Thanks for any help.

Hemant K Chitale wrote:
Before jumping in to Active Data Guard, one needs to evaluate :
a. Is there really a need to run queries on the Standby ? The Standby could / should be at a remote site so queries are "across the network". Depending on the nature of the queries and the volume of output, the "performance" of the queries may not seem to be the same.
b. If the database is not in Maximum Protection mode, the data "seen" at the standby may not be in "real-time" synch
c. Not all applications are truely read-only when querying. Some applications use "jobs" that write to tables when querying. Such would not work with Active DataGuard. (example : EBusiness Suite). There are very complicated ways of handling this -- and one needs to consider if the complications can be introduced and supported.
Over the network accessing standby read only is really not an good idea, I think no one will compare performance with primary and standby,
But some of them they want to validate data which are very critical, as it is matching with primary or not, Its an added advantage with ACTIVE DATAGUARD
Prior to that until unless stop MRP, open database and then we need to validate, So there is an interruption of recovery, I can say its also an advantage where there is no interruption of recovery.

Pros and cons of using disksets for SUNW.HAStoragePlus

Hi,
untill now we were usign disksets for SUNW.HAStoragePlus for installing HA Oracle on both Sun Cluster 3.1 and 3.2.
On the article ( http://www.sun.com/bigadmin/features/articles/cluster3.1_oracle10g.pdf ) with the title "Installing and Configuring Sun Cluster 3.1 Software for Oracle Database 10g HA" the author prefers using just the disk devices for SUNW.HAStoragePlus.
What are the pros and cons of using disksets for disks you'll use for SUNW.HAStoragePlus?
I think that if you do not need to add more than one disk to a diskset there's no need to to use disksets. So, you can eliminate a problematic layer such as SDS. What do you thnik and which option do you prefer?
Murat BALKAS

some more details :
On " Chapter 4 . Configuring SolarisVolume Manager Software" of "Sun Cluster Data Service 16 for Oracle Guide for Solaris OS"
(http://docs.sun.com/app/docs/doc/819-2980?l=en&q=Sun+CLuster+3.2 ) SDS disksets we use for HA-Oracle installations is explained in detail.
     Our procedure to create diskset to locate Oracle files is attached.
     After reading the article, I realized that using disksets is not a
must for filesystems to be mounted as SUNW.HAStoragePlus. If yes, I
would prefer using the disk devices directly instead of putting them
on disksets so that I can eliminate one for layer which is the problematic SDS layer.
     Our disk devices ( below /dev/did/rdsk/d9 and /dev/did/rdsk/d12 ) are
disk partitions from a RAID-5 logical drive on the storage.

Pros and cons of using DB LINK

Hi
I am planning to use dblink in my current project to acess external database .But is there any other alternative to this ? What are the pros and cons of using Oracle DB Links ? Can anybody help me on this ?
Thanks in advance .
Pradipta

Well, it depends on where you want to access the other database from. If you want to access tables in database B from a stored procedure in database A, then you have to use a dblink to do it. If your front-end application sometimes needs data from database A and sometimes needs data from database B, then you could establish two connections, one to each database, in your front-end, and use the appropriate connection for the different queries.

Pros and cons between the large log buffer and small log buffer?

pros and cons between the large log buffer and small log buffer?
Many people suggest that small log buffer (1-3MB) is better because we can avoid the waiting events from users. But I think that we can also have advantage with the bigger on...it's because we can reduce the redo log file I/O...
What is the optimal size of the log buffer? should I consider OLTP vs DSS as well?

Hi,
It's interesting to note that some very large shops find that a > 10m log buffer provides better throughput. Also, check-out this new world-record benchmark, with a 60m log_buffer. The TPC notes that they chose it based on the cpu_count:
log_buffer = 67108864 # 1048576x cpuhttp://www.dba-oracle.com/t_tpc_ibm_oracle_benchmark_terabyte.htm

Dataguard in 9i ----Pros and cons

I need to setup dataguard on the client side
IBM AIX 5.3, ora 9.2.0.6
Whats are the Pros and Cons in Oracle Dataguard 9i
share your Experinece please

I manage the setup Dataguard environment on Windows
One more question
IF the Primary database goes down how can i bring the Secondary UP?
in this case i assume it is a failover...
Since STBY has a different database name how does the end user connects to the standby?
Do i need to change the APPserver configurations and tnsnames.ora or ORacle will handle it
Thanks to Syed Jaffar hussain(The Human Fly) for the documents he has provided
whihc he sent almost 6 months back on Dataguard
What happens when a DDL happen on a Primary database
Does the redogenerated on the primary gets applied to the standby..?
Should get applied isnt it

Approach for O365 mails (pros and cons of both)

Hi Team - What is the right approach to access seamless, flawless emails of O365 in our laptops having Mavericks OS and MailMail . Is Office 2011 for MAC the right choice or should we stick to native MailMail for O365 mails (pros and cons of both).
We attempted with native messaging client but are facing lots of issues related to synchronization, delay, missouts etc... & we are not sure if we shift our users to Office 2011 for MAC, that will fix up the issues.
Please advise..
Best regards,

Database Register in two way :
1.) Static Instance Registration
2.) Dynamic Instance Registration
** Static Instance Registration:
add the entries in $ORACLE_HOME\NETWORK\ADMIN\listener.ora file or by using the GUI
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = xx.xx.xx.xx)(PORT = 1521))
)When you check Listener status --> unknown because no mechanism to guarantee that the specified status even exists.
**Dynamic Instance Registration
or service registration , registration is performed by the PMON process an instance background process of each database and doesn't need any configuration in the listener.ora

Pros and cons of using iFS

HAI ALL,
assuming that i have stored all of my data(both RDBMS and no-relational data html files,xml files)in an iFS.the first thing i want to ask u is
1)if i want to read the iFS and display only the RDBMS data from the iFS ,how fast it can be done compared to traditionally storing the RDBMS data in a table in oracle8i ?
2)if i want to use indexing,how fast is iFS compared to doing indexing in oracle8i ?
3)if i want to search for a particular record how fast is it compared to doing the same in an RDBMS table in oracle8i ?
4)say i want to mirror the contents of the iFS from one oracle8i server to another oracle8i server,what are the pros and cons ?
throw some light on the above points which is crutial for us to either go for iFS or not?
awaiting reply

Ravi, I sorry, but I don't understand your questions. My comments are preceded with >>.
Assuming that I have stored all of my data--both RDBMS and non-relational data, namely html files and xml files--in iFS, the first thing I want to ask you is:
I don't know what you mean, "store your RDBMS data in iFS". You store RDBMS data in the Oracle database directly. 1) if i want to read the iFS and display only the RDBMS data from the iFS, how fast it can be done compared to traditionally storing the RDBMS data in a table in oracle8i?
You don't store RDBMS data in iFS.2) if i want to use indexing, how fast is iFS compared to doing indexing in oracle8i ?
It's the same. Under the covers, iFS uses both the normal RDBMS indexing for its metadata, and the normal interMedia Text indexing for the non-relational data.3) if i want to search for a particular record how fast is it compared to doing the same in an RDBMS table in oracle8i?
It's the same. iFS uses the normal RDBMS searching capabilities under the covers.4) say i want to mirror the contents of the iFS from one oracle8i server to another oracle8i server,what are the pros and cons?
I'm not sure what you mean by "mirror". Are you referring to replicating?null
