LED Displays - pros and cons
I have a fairly new Macbook Pro and my display is pretty good. I only have one red pin head sized pixel that is stuck. My question is simple - what are the pros and cons to the upcoming release of LED monitors.
It will, yes, but current LCDs that use florissant bulbs do last a long time. I used a 6 year old Powerbook G3 and its LCD was just as bright as the iBook G4 I replaced it with two years ago (although neither were as bright as my MBP).
That is why energy saver by default dims the display after a short time of inactivity. Its also for power saving, but it also helps lengthen the life of the florissant bulb. It would only go down fast if you used it at 100% all the time. Just adjust your screen brightness based upon lighting conditions is my recommendation.

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.
regards
PoonamI 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. -
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?848428 wrote:

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. -
KM Cache and iView Cache - Pros and Cons
Hi All,
Can anyone tell me which Caching mechanism is better - KM Caching or iView Caching ?
What are the Pros and Cons of KM Caching and iView Caching ? Which type of caching is recommended ?
Any kind of help is appreciated.
Regards,
AdrenHi Adren,
As to my understanding, with Portal Cache, we can achieve the following:
1. Significant improvement in the interface response time
2. Unnecessary, additional page generation (re-rendering) is avoided when you call a portal page
3. Web browser-like caching for server-based, dynamic pages in the Web (such as the BW Application Web)
Cache monitor to monitor the current status of all active caches in your system landscape. The data displayed in the cache monitor can be used for evaluations
KM cache might eb better than Iview cache.
Please check the below links we might get soem info about the type of cache which is preferable.

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.

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
nullRavi, 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 -
All is in the title, so I repeat it below with a better identation.
What are the pros and cons of
1) choosing to use the SAME
Apple ID for iCloud services on one side, and
purchases on the iTunes Store, App Store, and iBookstore, on the other side; or
2) to have and use two separate Apple Ids for these "two sides"?
P.S.
I have loads and loads of free podcasts in iTunes in my iMac, that are certainly more thant the 5 gigas the iCloud provides for free, so I don't want those to go to the cloud. But this is perhaps a different question...
Also need to mention that I have itunes on a mac, a pc and an iphone.
Sorry to look so silly with this question, but I don't get the "big picture".You need to create a user account for your wife (or yourself depending on who has the current user account). When syncing, each of you should sign in as a separate user, login to iTunes and then sync. I had this problem when my sister got an iPhone. When we did her initial sync, everything on my iPhone showed up on hers. Apple gave me this solution.

What are the Pros and Cons while joining tables at DF and Universe level
Hi Experts,
I am new to Data federator designer. I need help on the below.
Could you please let me know the Pros and Cons while joining the source tables in data federator
And While joining the DF target tables in universe designer.
Regards,
GanaHi,
1. I have created target tables based on source tables with one to one mapping and then join all target tables in universe.
Ex: Source tables: Infocube text tables, fact tables and 3rd party data base table
Target tables:Target tables are same as source tables
--- Yes this is the way to create target Tables and join them in the universe.These target Tables gives you the flexibility like in future your requirement is to add one more object based on some calculation which is not possible in the universe so that time you can create one more column in the target table and do the calculation. at the same time if you are using source table you can not do anything.
2. Created single target table with all objects of source tables and merged all sources tables data.
Ex: Source tables: Infocube text tables, fact tables and 3rd party data base table
Target table: Single table.
--- This is bit complex structure to merge all tables data in the one target table.in this situation you have to put more efforts and it is more complex.basically this type of target table is useful when you are merging data by multiple source into single or creating one target table based on the union of tables by adding two mapping rules or more and you can not join tables in universe.
Better approach is first 1. create target tables based on the source tables and join them in the universe.
Thanks,

Pros and Cons not determining / having a Delivery Plant in Sales Order?
Hi Mates
Here I have come-up with one more (weired?) requirement from my client.
We have two plants manufacturing same product and supplying to all customers (some time in same sales order with two different line items).
At the timeof creating a sales order, marketing does't know from which plant the material will move and hence they don't want to fill the Delivering Plant field (VBRP-BUKRS at Shipping tab) for each Item.
They are insisting me to map it as above though I had explained about various pros and cons for not determining a mandatory delivery plant
in sales order like the requirements and shipping stuff.
Yet, yet they want this.
Has anyone come across this kind of requirement before? What best you had done for that?
Can I ask you what are the Pros and cons on not having a Delivery Plant at Sales Order level?
what if I could determine it Delivery level?
Any comments, suggestions, replies and advices are taken humbly.
Cheers
Ajay Kumar VeerankiDear Mahulenka
Thanks a lot for the reply. It do have helped me.
Yest it is VBAP-WERKS (typo error ).
Infact I had given the same solution for the issue.
Interstingly, they are insisting on a better solution fit for their requirement. Anyway shall 'highlight' the points again to them try to get it solved
Just wondering has anyone faced the same situation before.
Thanks again for the reply and good luck

What are the Pros and Cons of Using Batch Numbers over Serialization
Dear SAP Gurus:
Will someone please give me the benefits of using Batch Management over serial numbers in this case scenerio, or vice versa:
Client wants to trace all the components of an assembly in a BOM. Even the Raw material. The client sends the material out today and has the vendor assign serial numbers to the individual pieces, the client gives the range of serial numbers to use. We are looking at using batch numbers to accomplish this and issue one material and batch number to a production order. Then use MB56 batch where used functionality to view history. I am wanting to understand the benefits of this. Please advise and points will be awarded as always.
Also, in this scenerio, can you issue multiple material/batch numbers to one vendor op that has its own production order?Yes it is a subcontract.
Example: This is the solution but need the pros and cons of doing this scenerio
Sheet of metal sent to vendor to make lets say 1800 peices of material number nas5703-01. All 1800 pieces come back and issued to a production work order using one bacth number for one material item so that batch number can be traced in history in MB56 and a fit up report. -
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
RajendraHi 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 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. -
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
PrasadHi 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

My PROs And CONs Opinion of This New Forum
Hello,
Since I've only been a member for a short time; my exposure has been limited; however, my opinions follow:
PROs
This forum has excellent support from "volunteer moderators" and Lenovo Staff. They are literally "all over the place" trying to assist in any way they can.
I like the forum layout; in that, it is categorized by "machine types" rather than desktop, laptop, hardware, software, audio, etc.
CONs
Some of the threads have grown to such an enormous size (I saw one with 517 replies) they have become almost useless. These enormous threads signal one of two things in my opinion. First, either the problem, presented by the original poster, has existed for quite some time without resolution and many keep reporting the same problem or the thread has just become a "me too" dumping ground. In any event, I would recommend that this forum's support group get together and evaluate the pros and cons of keeping super-large threads open for continued response by members of the community.
BTW, I'm marking this thread as an accepted solution because it is my opinion.
