Reply from LCC352 on Jun 19 at 3:31 PM Hi, Luis - The company I worked for had UNIX/Oracle for 16 years. The decision was to move off both platforms to fall in line with the rest of the company, which was Windows/SQL Server. I headed up the project to move the ECC 6.0 instance. It went very well, coming in on time and slightly under budget.
There have been NO issues with Windows/SQL Server 2008 R2. The database size was greatly reduced due to the compression factor built into SQL Server, and the response time was still sub-second for normal transaction processing as it was with UNIX/Oracle.
With respect to DBA services, one can say that you don't "need" to have a DBA with SAP knowledge; the question is do you "want" to have that situation? Our DBA was an Oracle DBA. We sent the person to SQL classes to understand the new database, retrieval engine info, etc. We also made the investment to take a couple of SAP classes geared towards DBA's. I did not regret that small expense in the overall scheme of things.
We never used SAP's support for those items you mention as we always had our DBA functions in-house so I can't comment on that per se. The only thing is I'm not sure it's actually covered under licensing agreements. It might be something separate that we did not opt to pay for due to having the skills in-house. What I CAN comment on is SAP support in general, which in nearly 18 years working with the product, I've not had an incident where I needed top level support and couldn't get it. I've had situations where we were dead in the water and SAP worked with us 24 hours/day until it was fixed. I've also used their Custom Development teams, which were also very good in all aspects.
For your last question, again, I can't comment.
Good luck!
- Lou

Subject: Advice On Selecting SAP Database
Dear all,
I need your help to resolve some doubts and shed more light on SAP. As background I'm system administrator working in an Oil&Petroleum company which soon will be implementing SAP ECC ver 6. Currently our ERP is Oracle (ex-PeopleSoft) JD Edwards. Almost 99% of our systems run on Windows and Microsoft SQL databases (Including JDEdwards) as well many other Microsoft Applications, we also have an Enterprise Agreement in place with Microsoft. Our business doesn't require High-Performance transactional database like banking or telecom would normally require, also our SLA is flexible so we don't need Clustering at all.
With that in mind, I get involved in the IT Team's that is evaluating which database we would choose for SAP. We directly discard HANNA and Oracle due to they're expensive and as I say before, our business don't have the needs of such features and performance, so our alternatives are Microsoft SQL Server or SAP Sybase AES. In regarding of costs, Sybase Licensing Is 5K more cheaply than Microsoft, this small margin forces us to look for other aspects to fundament our decision.
I been talking with local SAP partners, and as expected they recommend implementing SAP with Sybase. However the strange part (at least for me) comes with the technical support, this is where I have some doubts that I would like to clarify:
1. - We been told that we don't need a highly experience DBA for SAP Database, in fact our DBA doesn't need to know anything of the SAP Database's, due to we won't touch nothing directly at database, all the configuration/chances related tasks are made only and exclusively through the SAP console, i.e.: installing patches/service pack to database, defragmenting/indexing database, and so... Am I misunderstanding anything or in your experience this statement true?
2. - We also been told that the "SAP Support" that comes with our maintenance will be in charge of almost everything, this would cover basics tasks such as defragmenting database, changing operating system configuration, installing patch to operating system, restoring databases, and so on… Am I misunderstanding or in your experience this statement is true?
3. – Thinking in my question two, what are the Tech supports level's that SAP provides to customers? And if possible some examples about what tasks I'm allowed to do and what task I should do with SAP Support?
4. – What other aspects should I consider if we chose Sybase as database?
5.- If you are using Sybase, approximately how much do you pay to SAP for support this database?
That's all I have doubts, I would be enormously glad for your time invested in help me.
Thanks in advance,
Luis Fernando. |
