Pros and Cons: OS X Server vs Linux

Maybe some of you using OS X Server can assist me with your experience.
I am running a multiplatform network consisting of Linux clients and OS X G4s and G5s. I am considering purchasing a Linux-based server. Are there any known compatibility issues that may arise using a Linux-based server with the Apple systems?

you can configure a linux or bsd or other *nix server to do whatever you want, and the macs should work just fine.
what do you need to do?
the "compatibility" question is too vague. yes, macs are compatible, but it depends on your needs.
post details, please.

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 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.

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

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

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.

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

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.

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.

SAPSPRINT vs Local Printers (Pro and Cons)

Hi guys.
Anyone can help me out citing pro and cons by installing a SAPSPRINT over windows vs having printers installed directy over the Iseries Server.
Its planned to install productive printers which are very critical, so we would like to devise the best approach.
By installing the SAPSPRINT would avoid the bottlenecks if the printers are installed locally?
Thanks!

Hi Markus, nice to see you.
I agree with the fact that a central print server you can have a better administration of your printers.
My concern is that based on Note 19706 - Tuning the Spooler, productive printers must never be defined with access type U or S, and all printers created on that print server are type U, which is the recommended access method for remote printers.
Group 1 (Productive printer):
All printers with the shortest possible response time.
For example: Goods receipt/issue sheets, delivery notes, patient entry sheets,...
Printers with a fast response (Group 1):
Devices with short response times must NEVER be defined with access type 'U' or 'S'. When a problem occurs (e.g. network problems, PC is switched off etc.), a single printer linked to a work process by access type 'U' disturbs all the connected printers. All printers in this group MUST be linked with access type 'L' or 'C' (depending on the operating system). If they are not linked to the server, they must be defined in the host spooler as "remote printers" and forwarded via the the host spooler.
So why this note recommends to put printers locally in order avoid network issues and so on, but SAP also recommends a SAPSPRINT as printing solution?
Does SAPSPRINT overrule any recommendation to local printers and is a definite solution way better than local printing?
Thanks Markus again

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

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
null

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

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

PROS and CONS of ArchLinux

This is a try to summarize the pros and cons of archlinux in one place, to have an overview.

[+] means "PRO", [-] means "CONTRA" and [0] means "only note"
Summary:
[+]: optimized i686-distro
[+]: free
[+]:[pacman]: Systemupgrade is one command 'pacman -Suy'
[+]:[pacman]: Dependency-control
[+]:[pacman]: no X needed
[+]:[abs]: need to write the building-function only once ... building another version of a package is extremly easy
[+]:[abs]: you can build the packages on your machine with one command
[+]: up-to-date packages
[+]: fully customizable
[+]: newbies have to learn some basics to use the power behind a real linux-station ([-] this takes some time :-) )
[+]: lilo or grub as bootmanager
[+]: the people behind are gentle, motivated and able
[+]: big package-repository; slowly but steadily growing --- separated in official, unofficial and unstable
[+]: 51 games :-)
[+]: newest kde, gnome, OpenOffice, Abiword, wine ...
[+] It takes less than 20 minutes to get a fully functional system rather than 5+ days like some other distros
[+] no internet requied during CD-Installation / no CD-Drive requied during FTP-Installation
[+] perfect to learn linux on it
[0]:[pacman]: needs fast internet-connection to stay always up-to-date easily
[0]: not really popular, because not known
[0]: Documentation in developement --- usable

Well put, dp. I fell in love with Arch for this very reason. After spending a couple of weeks on a variety of distros (Redhats 7.3, 8.0, Mandrake 8.1, Libranet 2.2), I found Arch and it ALLOWED me to learn so much more than these other distros. Arch IS very user-friendly.
hmm this would be contrary to your concept of "user-friendly", no?
[cutcutcut]
i know alot of people don't want to have to learn anything about their computer or their OS but that is just plain stupid i think. you need to know a little something about most other tools you use in order to use them properly and safely. point and click is like a self hammering hammer .... a waste.
EDIT: i used to be very opposite of this opinion before i used arch. but being "forced" to learn more has been very helpful for me and others.
Against my concept of "user-friendly"? No. I think that Arch Linux is extremely user-friendly, but not so newbie-friendly. Arch, as you say, has "forced" me to learn alot, and enabled me to do so by being simple and transparent; things work as they say they do, without to many surprises, but they are not self-explanatory, which is what a newbie requires.
Now, let me clarify: I wasn't suggesting an actual GUI install. I think Arch's current install (while imperfect) is much better than, say, Redhat's. Any user should be able to navigate the menus easily and make the choices that need to be made. I am against a GUI installer for the forseeable future as well. I was referring to including an option for HWD (which you say will be included in the future, so scratch that) and an option to install GUIs for sysadmin (like one for pacman, etc.).
It seems your against this on the basis that it would impede learning a bit...well...Is the Arch Linux goal to educate about Linux? I mean, I think that it's possible that a better goal might be to spread the USE of Linux, which might be facilitated by including some admin tools. Only as an option. People who want to learn will, and people who don't will only become frustrated and abandon ship.
I would worry more about impeding the spread of what I consider to be an incredibly powerful, flexible computing platform, one that is quite user-friendly and potentially quite newbie-friendly...
Okokok...all that being said, I understand exactly what you're saying and can appreciate your view and desire to preserve Arch as "unspoiled" in a certain sense. Definitely a valid point.
So, before any of this newbie stuff is truly considered, I think we can all agree that the Docs should be polished to a healthy glow.
P.S. Sarah, I though you had retired from the AL team, but I'm glad to see you around the forums just as much as ever!
