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.

Pros and cons for using single/multiple database

hi
could anyone tell me in which senario we can use multiple databases and advantages and disadvantages using multiple databases over single database (with different tablespace)
thaks in advance
hari

depending on your situation you can probably think of different answers. You ask for a 'general' rule of thumb... well, some things that pop into my mind:
- different usage by applications. e.g. you have a transactional application storing and modifying data and you also want to do analytics. You might want to build a seperate database/datawarehouse that you can use for analytics. by splitting it up you can tune both databases to work best with the application using it.
- sensitive data and many different users. e.g. the marketing department does not need to have access to the finance department's data (salaries, etc). give each department a separate database and only load the data needed/give access to the data needed.
Just some thoughts, you can think of more when confronted with a certain situation.

Pros and cons of EPM and Classic Application.

Hi All Experts,
can any one tell me what are the pros and cons if create EPM Application
and pros and cons if we create Classic Planning Application
this is really urgent we have to submit this to our client as soon as possible

Hi,
The main difference between using of classic and EPMA is I think hidden in the first letter of EPMA. EPMA is for Enterprises where multiple performance management applications are considered applicable. When you have an HFM application, a planning application, a performance scorecard application, a couple of essbase cubes around and lots of reports pulling data from all these, sharing data and metadata becomes crucially important. And no mistake, classic planning is as good as EPMA planning and easier to handle, however, if your company or client is thinking of having a total EPM solution in place, then EPMA is the right choice. However, since you can always convert your classic app to EPMA but you've got only one bullet to fire, it might be wise to stick with classic application until your client/company starts imagining that sort of ambitious goal.

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.

Siddharth.

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!

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,
Adren

Hi 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 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.

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

Neptune for UI development Pros and Cons

Hi ,
we are evaluating neptune for UI development for what are the pros and cons of using neptune.
i see only that webdynpro abap developer can be easily moved to neptune , some javascript knowledge is still required.
some question
1) can neptune make calls to odata services ? do that requires code in javascript or ABAP
2) any accelerators provided by neptune like for workflow scenarios , list and details .
3) can sap standard fiori apps extensibility or modification is possible through neptune
4) security if its accessing business functionality directly
regards
Yashpal

Hi Yashpal,
I will give you my view, but as Robbe says I work for the company and other SAP developers like DJ Adams has other development tool preferences than me ( I call his Sublime Text development spaghetti coding and he sees Neptune as a crutch that restricts a developer's freedom but this is just a friendly point-of-view discussion and I have promised him a beer in Walldorf next time our paths cross there)
So the important message is that SAP has opened up their platform for different development tools and it is now a choice for the individual developer or SAP customer. This is a fantastic move by SAP and I think a bit overlooked by the community, Look at the new Xamarin partnership as an example (and yes they are a competitor, but I did mention them )
Now the pros of Neptune are in my opinion:
ABAP developer friendly development (removed 90% of JavaScripting needed)
Connected to the SAP transport System (Software Logistics as is)
Drag Drop designer that gives structured code (easy for a new developer to take over code, compared to the spaghetti provided by DJ <- I'll need to buy a few extra beers for that remark)
Native json communication provided by the Neptune Server (you can argue all you want about Odata, our solution is more flexible gives incredible performance and superb and easy to use offline capabilities)
Integration with Adobe build, use an SAP program to generate hybrid apps (The average ABAP developer does not install cordova and build hybrid apps - with Neptune he/she does)
Integration with SMP. Automatic connection with the REST API's of SMP both on-premise and in the Cloud
Reduced time to market. One of the largest SAP implementation partners in the Nordics stated that Neptune reduced development time by 80%
Free templates (Advanced templates such as fully functional PM, HCM, SD templates are available Experience | Neptune Software <- sorry for the marketing but you did ask)
UI5, all of the other third-party tools (Not SAP tools like App Builder, Eclipse etc) uses non UI5 frameworks. I personally believe that SAPUI5 (UI5) is the future of SAP UX and thus it only makes sense to keep a common and future-proof framework.
Network crunching. We optimize all networking. Which makes sense for mobility.
no extra infrastructure needed - it is a certified add-on and takes 15 mins to install.
Works with most versions of SAP. We even have alot of customers using 4.7 (we need the ICF so nothing lower). This is something the community often forgets. Yes it is cool to play with the latest Netweaver release, but do our customers have that installed?
Cons (woot!)
Cost, even if Neptune is very affordable it still requires license for productive usage (free for developers though - and hey we need to live as well ) So custom coding is cheaper in respect to license (but not in TCO in my opinion)
Generated code, even if we have added as much freedom to code custom JavaScript as possible there will always be restrictions in generated code compared to notepad. (But I haven't met an issue that couldn't be solved by custom coding in the Neptune Application Designer yet)
Other backend systems. Neptune is based on ABAP and as such it obviosly works best with an ABAP backend.
.... (Add stuff from other non Neptune ppl )
Regarding your questions:
1. Yes you can use Odata, best way is to consume it on the ABAP level, but you can of course consume it through JavaScript as well (Not recomended by me)
2. Yes see above (free templates and also premium templates by our partners)
3. No you can't modify a fiori app with Neptune, but the two solutions work perfectly together (You can add Neptune apps in the Fiori launchpad) One of our partners have created an RDS solution based on both Fiori and Neptune.
4. Neptune is an add-on to Netweaver and as such has no extra security in itself beyond that (And we seek not to do that). But we support any security you wish to add on top. I strongly advice having a look at the SAP Secure offering (App protection and MDM) as well as SMP (also the new Cloud edition which gives easy affordable protection for your backend)
So that was my very biased answer

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,
Gana

Hi,
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,
Amit

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 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
Prasad

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

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.
