Pros and cons of changing DNS servers?

Hello guys, First of all I am a non technical person related to DNS servers. So I want to know what are the pros and cons if you change your DNS servers?
I wanted to access Netflix but its not yet available in my country so I came across http://unotelly.com/ . They provide a method to access but by changing DNS. Can someone guide should I do it? What are the pros and cons? Thank you

The DNS is what translates in and outgoing URLs to your local domain server. Changing it may have no adverse effect. It could result in faster or slower translations, but you may not even notice either. However, if it does not work properly, then you will not get web sites in your browser until you revert back to a DNS that you know works or delete all added DNS entries which returns to the system default.

Pros and Cons Between UNIX and Windows Servers

Hi,
Currently the business I work for runs SAP on UNIX, but there is talk of moving to Windows servers as there are more skills available in SQL.
It is our belief however, that UNIX servers are more 'stable' than Windows. We believe it would cost more in staff time if there was a transfer to Windows because of more system downtime, due to a larger amount of server updates.
I would like to know the experiences and opinions of' anyone who has made the switch from UNIX to Windows, or vice versa.
Has anyone considered moving to Windows and decided against it? What were the pros and cons?
II'm sure this is an issue that has been considered by many experts. I look forward to reading your responses.
Regards,
Luke

Thanks Michael, that thread is really useful and gives me some good information for my report.
I'm still interested in hearing more opinions on this. Is there anyone that has successfully fought off a proposed change to Windows from UNIX based on pros and cons, or vice versa? I want to hear both sides of the argument and have a really interesting, opinionated discussion in this thread.
Regards,
Luke

Same SID for QA & Prd systems - pros and cons?

We have the foll systems:
1. Enterprise Portal 7.0
2. NWDI 7.0
3. NW 7.0 (with XECO - Ecommerce)
4. TREX 7.1
5. Content Server 6.40
6. ECC 6.0
Currently the QA and Prd systems have the same SID and system/instance no, although they are on different hosts.
We would like to know what are the long term pros and cons for keeping the QA and Prd SIDs the same for all systems.
We are already making a list, so thought we might as well get more inputs from the community too.
We already have this arrangement for the past 3 months and have not faced any major issues.
A couple of cons though:
1. Cannot use solman as it cannot distinguish between the diff servers with same SID
2. ABAP transports from QA to Prd have to be manually done (cannot use STMS)
Thanks

Hi Manoj,
Changing the SID of java systems is a very tedious procedure. Hom sys copy is just a part of the SID change...there are a whole lot of configs to be done after that...the task is eq to a new setup of systems
For once, the efforts put in are huge..you can see there are 5 systems..besides, it will involve coordination from all teams - basis, development, functional, project management.
Here are a few advantages that we know of:
1. No efforts reqd to change back to original SID
2. During disaster recovery, we just have to restore the production database on QA and change the hostname, whereas its not so in case of having diff SIDs
3. For end-users this will be transparent because they will be using the hostname in the URL which is anyways different
We have the same SIDs for the past 3 months and have not seen major issues, but we also would like to know from the long term perspective if there are any risks that we have not foreseen...hence we seek help from the community.
Hope its clear now
Thanks for your response

What are the pros and cons of installing java+abap stack for portal?

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

Pros and cons of creating a table with key

Hi Folks
I have some tables where there is no key defined in the source system. What is the best way to build such tables. In my case the source system is Teradata.
I have 25-30 columns in dimension and what is the best way to load this data where there is no.
What will be the Pros and Cons if I have a table without a key or if I create a table with 25-30 keys.

I recently purchased a Mac Mini and am using it with my TV. Here's what I found:
Using the HDMI connection on the Mac Mini, the image on the TV is very harsh. It's very bright, high contrast and garish colors. I did a lot of testing and am convinced this is due to the HDMI Display Profile in OS X Yosemite. I could not find any way to change the display profile in the Mac Mini as long as HDMI was the connection.
Using the miniDisplayport/Thunderbolt connection on the Mac Mini, with the Apple miniDisplayPort-DVI adapter and a DVI-HDMI cable the picture is perfect. (Note, however, that this connection only carries video; if you want audio you will have to use a separate cable to connect the Mac Mini audio line out port to your TV's audio line in port.)
That said, the larger the TV the less quality you will have displaying text. I suggest using a 21" or smaller TV as a monitor if you will be doing text work.
My setup is with a 40" Sony Bravia 1080p HDTV and the primary use is for video (concerts, movies, Skype, etc), not office apps. As I said earlier, the picture is perfect - brightness, contrast, colors, resolution are as nice as I could ask for.

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.

Pros and cons in setting AD domain trust into my AD domain for more than 10+ AD domain and some with same FQDN or label ?

Hi,
Can someone please share what is the pros and Cons of trusting AD domain for more than 10 different AD sites into my existing single domain forest let say ParentCompany.com ?
At the moment I only have one single forest AD domain with the Domain and Forest functionality Windows Server 2003. The main domain controller FSMO role holder is in the Data Center spread across three different VMs running on Windows Server 2008 R2.
The main/parent company has acquired smaller business chain of 15+ offices in which they have their own Domain Controller and also their own domain, sometimes they also got the same AD domain between them (no trust or whatsoever in those 15+ AD domain).
Sounds crazy but yes, there is no standardization in them or whoever manage their IT infrastructure previously.
I'm now considering what are the benefits of creating the AD domain and trust versus importing those AD objects into my domain and then decommission them.
No need to worry about Exchange Server since all of the user in those sites connecting to the RDS to my ParentCompany.com terminal servers.
My requirements or goal are as follows:
1. Simplify the AD domain structure & maintenance
2. Try to avoid the disruptions of the user in terms of downtime and selecting multiple different domain everytime they login to their PC or SharePoint sites.
any kind of help and suggestion would be greatly appreciated.
Thanks.

Can someone please share what is the pros and Cons of trusting AD domain for more than 10 different
AD sites into my existing single domain forest let say ParentCompany.com ?
I think you mean 10 AD domains.
Managing multiple domains can be difficult for administration. I usually recommend using a single domain in a single forest with OUs to separate resources whenever it is possible.
However, if you can't do that then you can simply create trust relationships between your domains. The advantage is that you can enable access to resources to different domains. I do not see cons here.

I would recommend consolidating your domains into a single one. ADMT is a migration tool that you can use. The advantage would be the ease of administration. Also, by having multiple DCs for the same domain across sites, you will take benefit of High Availability
of your and DRP.

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 for single sales organization and multiple sales organization

Hi!
Does anybody have a good data of Pros and Cons for Single Sales Organization vs. Multiple Sales Organization.
Thank you!

Hi,
Actuall it all depends on the business process.
I will explain the answer to you through a practical example
like Ford, it has sales and services all across globe.
It is not advisable to manage all of its activities under only one sales organization, say Ford Inc.
So what it does is de-centralises the whole process according to the country, region so that the whole process is divided and hence can be managed more effeciently.
Hope this helps you in understanding the basics.
One sales org always provides you with very less data to update and maintain, while many sales org makes the scenario more complex.
One sales org always gives you the flexibility to bring any changes to the current scenario, while in multiple sales org to bring a change its a tiresome job.
These are some of the advantages and disadvantages of one to many sales org.
regards,
Siddharth.

Pros and Cons of Application Isolation/Multiple server instances?

Hi. I'm setting a new server using ColdFusion Enterprise with Apache to migrate several web application from and old server with ColdFusion 7 server. I'm currently doing research regarding multiple server instances in order to have a separate server for production apps and another for development apps (see http://help.adobe.com/en_US/ColdFusion/10.0/Admin/WSc3ff6d0ea77859461172e0811cbf363c31-7ff 5.html and https://wikidocs.adobe.com/wiki/display/coldfusionen/Using+Multiple+Server+Instanceshttp:/ /). In addition, I'm also doing research regarding application isolation to have separate production application in separate servers. I'm trying to identify all pros and cons for both "Application Isolation" and "Multiple Server Instances" to make a decision on whether I will proceed in applying these techniques. I have found several links that talk about some of the advantages but have not been able to find anything regarding possible disadvantages. Have anyone in this forum has used any of the techniques, and can provide more information/experiences regarding the pros and cons?

Hi Ricardo_Lorenzo,
Whether to go for Multiserver instances or Single server, is totally a user requirement based decison. If a user has Single website, or multiple websites (of the same nature, in terms of functionality), usually the part of same domain, then they would go for Single sever installation. One single instance will handle the requests from all the websites (if there are multiple). There would not be a clustering/failover setup within ColdFusion and can use the ColdFusion Standard or Enterprise version.
On the other hand, if a user has multiple websites, all with different functionality and have multiple applications (may or may not) running, then they can go for Multiserver installation. Each website can be configured with individual instances. Clustering can be done within ColdFusion if needed. One would need an Enterprise license of ColdFusion for the same.
Hope this helps.

Anit Kumar

Can someone please help me... i'm about to buy a new macbook pro and i need some pros and cons of SSD

hi.. i'm about to buy a new macbook pro and i need some pros and cons of SSD.... i'm not sure which is really better, the regular hard drive or the SSD... because if i buy the mac with SSD it would be the 128GB, so i want to know how would that affect the overall performance of the computer...
Thanks!

I would suggest that you purchase the SSD through a third party source. You will save money that way.
Regarding the performance, go to the OWC web site. They have bench tested their SSD vs conventional HDD and have published the results for anyone to see,
The difference between the 128GB and the 256GB drives is capacity, no practical change to performance.
Ciao.

Dataguard in 9i ----Pros and cons

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

Error code text file or Error ring, pros and cons of each

I'm looking for some community input on the pros and cons of using either the Error Code Text file, or the Error Ring for creating custom errors in an application. My question comes about as a result of this post.
I've used the Error Rings exclusively in the past to avoid the extra maintenance steps of bringing the text file along with the LV project and source control. I assumed the error information was simply converted to ring constant. But with my linked post above, I'm wondering how deep my mistakes may cut me.
Please weight in on this with pros/cons, , and any past experiences that may be helpful.

Actually Hooovahh and Jeff are right. As you can see in that way you can prioritize the error that you need to read or in other case ignore. In the same time you can create the error that you want.
In this link in the last interaction they upload some pictures where you can see the way for make.
