Best practice: Retrieving data using DI server

Hello experts,
We are going to build a web shop using DI server. We are not going to use B1WS, because it is not supported and it seems like a lot of people can't get it to work (and so can't we).
DI Server supports some Data Retrieve Messages, but most of them have a very restricted use. GetItemList for example only returns the item codes and item names. I can't limit the amount of returned values and I can't add columns to the results (if I'm mistaken about this, please tell me so!)
What are best practices for this?
Do I use the ExecuteSQL Data Retrieve Message in those cases (like 90-95% of the time) or do I use combinations of Data Retrieve Messages?
Thanks for your time!
Vincent

Hi Vincent,
What you mentioned are actual problems with current DI API and DI Server. You can't set the amount when using GetItemList both in DI API and DI Server. The design maybe just consider the common requirements in mid/small size companies. So I think it's better to use ExecuteSQL if you have special requirement.

SAP Best Practices for Data Migration :repositories only on MS SQL Server ?

Hi,
I'm implementing the "SAP Best Practices for Data Migration" (see https://websmp109.sap-ag.de/bp-datamigration).
As part of the installation you have to install MS SQL Server Express Edition. The installation guide contains detailed steps to do this. All repositories for Data Services should be running on SQL Server, according to the installation guide.
The customer I'm working for now does not want to use SQL Server, but DB2, as company standard.
So I use DB2 for the local and profiler repositories.
I notice however that the web application http://localhost:8080/MigrationServices does not support DB2.The only database type you can select in the configuration area is MS SQL Server.
Is this a limitation, a by design ?

Hans,
The current release of SAP Best Practices for Data Migration, v1.32, supports only MS SQL Server. The intent when developing the DM content was to quickly set up a temporary, standardized data migration environment, using tools that are available to everyone. SQL Server Express was chosen to host the repositories, because it is easy to set up and can be downloaded for free. Sone users have successfully deployed the content on Oracle XE, but as you have found, the MigrationServices web application works only with SQL Server.
The next release, including the web app, will support SQL Server and Oracle, but not DB2.

The best practice for data archiving

Hi
My client has been using OnDemand for almost 2 years, there are around 2M records in the system(Activities), so just want to know what is the best practice of data archiving, we dont care much about the data in the 6 month ago.

Hi Erik,
Archival is nothing but deletion.
Create a backup cube in BW. Copy the data from your planning cube to the backup cube, and then delete that data region from your planning cube.
Archival will definitely improve the performance of your templates, scripts, etc; since the system will now search from a smaller dataset.
Hope this helps.

Microsoft best practices for patching a Cluster server

Good morning! I was wondering if you had any web resources (Webcasts) or whitepapers on Microsoft best practices for patching a Cluster server? I will list what I seen online; the third one was very good:
Failover Cluster Step-by-Step Guide: Configuring a Two-Node File Server Failover Cluster

Patching Windows Server Failover Clusters
http://support.microsoft.com/kb/174799/i

Hi Vincent!
I assume this step-by-step guide can also be used if you have more then 2 nodes, as long as you make sure majority of nodes are up (and quorum disk is available).
I just had a strange experience during maintenance of 2 nodes (node nr 7 and nr 8) in a 8 node hyper-v cluster R2 SP1 with CSV. I used SCVMM2012 to put the nodes in maintenance mode. (live migrating all resources to other nodes.) I then look in "Failover cluster
manager" to check that the nodes had been "Paused". And yes everything was just fine. I then did windows update and restartet, no problem. But after restart I wanted to run PSP (HP's update utility) to update some more drivers,software etc. During this PSP
update, node nr 02 suddenly failed. This node is not even a HP Blade, so I'm not sure how, but I know network NIC drivers and software where updated from PSP. So my question is:
Does changes in "Network Connections" on nodes in "Pause" mode affect other nodes in the cluster?
The network are listed as "Up" during Pause mode, so the only thing I could think of is that during PSPs driver/software update, NICs on node 07 and 08 were going down and up differently somehow making Node 02 fail.
So now during maintenance (Vendor driver/software/firmware updates, not MS Patches) I first put the node in "Pause" mode then I stop cluster service, (and change it to disabled) making sure nothing can affect the cluster.

Is it possible to retrieve data using RFC alone with out using BAPI ?

Hi ,
Is it possible to connect SAP to Non-SAP systems to retrieve data using RFC alone with out using BAPI ?

Hello Nelson,
Could you please explain how this can be done. Because my understanding is that only BAPI can be used to connect Non SAP and SAP system not RFC function module.

Retrieving data from OBIEE server using ODBC

Hello.
I am having difficulty retrieving data from OBIEE 11g using the ODBC connection. My intention is to read OBIEE Server data via a SQL statement issued from an Oracle database using gateways.
I have read and followed the material here:
http://download.oracle.com/docs/cd/E14571_01/bi.1111/e16364/odbc_data_source.htm#CACBFCJA
I have also tried this from Excel 2007, but have not succeeded:
http://gerardnico.com/wiki/dat/obiee/import_data_from_obiee_to_excel
I have setup a gateway in Oracle and a database link. Iknow it is connecting because when I change the password to something invalid, I get a message about not being able to connect due to username/password.
I have taken a query from Answers (the advanced tab) and tried running it from Sql Developer. The nsqserver.log file ends up with the following Notification:
[nQSError: 13013] Init block, 'DUAL Num (=3)', has more variables than the query select list.
As an experiment, I am using the SampleApp, and have generated the following query in Answers:
SELECT s_0, s_1, s_2, s_3 FROM (
SELECT
0 s_0,
"A - Sample Sales"."Products"."P3 LOB" s_1,
DESCRIPTOR_IDOF("A - Sample Sales"."Products"."P3 LOB") s_2,
"A - Sample Sales"."Base Facts"."1- Revenue" s_3
FROM "A - Sample Sales"
) djm ORDER BY 1, 2 ASC NULLS LAST
Is there a way to issue this query from a database client like SQL Developer? I have setup a database link called obiee via gateways to the ODBC connection, and add @obiee after the table name in the above query, but get the nqs error above.
Thanks for any help. I can provide addl info if such would be useful.
Ari

That would explain my difficulty. I went to the link:
http://download.oracle.com/docs/cd/E14571_01/relnotes.1111/e10132/biee.htm#CHDIFHEE
that describes the deprecated client. I am confused by the statement there:
"one of the many widely available third-party ODBC/JDBC tools to satisfy previous NQClient functionality"
My understanding of ODBC is not very strong, so please bear with me. The statement above is talking about a client tool, but there also needs to be an ODBC driver available for BI Server. I may be a bit confused between driver and client, and what piece nq handles. I don't understand the comment about third-party ODBC when it comes to the driver piece, as that must be coded for BI Server. When I go to create a new DSN, the only driver that makes sense for me to select is:
Oracle BI Server 11g_OH<id>
That all works fine to setup a DSN. But I am unable to connect from Excel, etc., using this DSN.
Put more simply, should I be able to connect to BI Server via ODBC - not using the deprecated BI ODBC client, but using other clients? Is there ODBC connectivity at all in OBIEE 11g?
Thanks,
Ari

Best Practices for Data Access

Good morning!
I was wondering if someone might give me some advice on some best practices for retrieving data from a SQL server in the cloud via a desktop application?
I'm curious if I embed into my desktop application the server address (IP, or Domain or whatever) and allow the users to provide their own usernames and passwords when using the application, if there was anything "wrong" with that? Where-in my
application collects the username and password from the user, connects to a server with that username and password, retrieves the data and uses it in-app.
I'm petrified of security issues and I would hate to start using a SQL database with this setup only to find out that anyone could download x, y or z and connect to the database and see everything.
Assuming I secure all of the users with limited permissions, is there anything wrong with exposing a SQL server to the web for my application to use? If so, what and what would be a reasonable alternative?
I really appreciate any help and feedback!

There are two options, none of them very palatable:
1) One is to create a domain, and add the VM and your local box to it.
2) Stick to a workgroup, but have the same user name and password on both machines.
In practice, a better option is to create an SQL login that is member of sysadmin - or who have rights to impersonate an account that is member of sysadmin. And for that matter, you could use the built-in sa account - but you rename it to something else.
The other day I was looking at the error log from a server that apparently had been exposed on the net. The log was full with failed login attempts for sa, with occasional attempts for names like usera and so on. The server is in Sweden - the IP address
for the login attempts were in China.
Just so know what you can expect.

ASM BEST PRACTICES FOR 'DATA' DISKGROUP(S)

In our quest to reduce operating costs we are consolidating databases and eliminating RAC in favor of standalone servers. This is a business decision that is a certainty. Our SAN has been upgraded, and the new database servers are newer, faster, etc.
Our database version is 11.2.0.4 with Grid Infrastructure 12.1.0.1. Our data diskgroup is RAID-5 and our fra is RAID-1+0. ASM has external redundancy. All disks are of equal size with equal storage performance and availability.
Previously our databases were on separate clusters by function: OLTP, REPORTING and ENTERPRISE CONTENT MANAGEMENT. Development/Acceptance shared a cluster, while production was separate.
The new architecture combines different functions onto one server for dev/acc, and another for production. This means they will all be using the same ASM instance. Typically we followed Oracle’s recommendation to have two disk groups, one for data and the other for FRA. That followed well when the database was the only one using the data diskgroup. Now that we are coming databases, is the best practice still to have one data diskgroup and one FRA diskgroup? For example, production will house 3 databases. OLTP is 500 GB, Reporting is 1.3 TB, and Enterprise Content Management is 6 TB and growing.
My consideration is that if all 3 databases accessing the same data diskgroup, the smaller OLTP must traverse through the 6 TB of content management. Or is this thinking flawed?
Does this warrant separate diskgroups? Are there pros and cons to this?
Any insights are appreciated.
Best Regards,
Sherrie

I have many issues to deal with in this 'consolidation', but budget reduction is happening in state and regional government. Our SAN storage is for our enterprise infrastructure and not part of my money-savings directive. We are also migrating to UCS blades for the infrastructure, also not part of my budget reduction contribution. Oracle licensing is our biggest software cost, this is where my directive lies. We've always been conservative and done more with less, now we will do with less, but different because the storage and hardware are awesome.
We've been consolidating databases onto RAC clusters and standalones since we started doing Oracle. For the last 7 years we've supported ASM, 6 databases and 2 passive standby instances (with Data Guard) on a 2-node cluster totalling 64gb of memory. The new UCS blades have 256gb of memory. I get that each database must support its background processes. If I add up the sga, pga allocated, background processes they take up about 130gb of memory, but also consider that there is an overhead to RAC. In all the years we've had Oracle, most of our failures, outages or downtime was because of RAC. On the plus side of that, the seamless failover saved us most times (not all times), but required administrative time for troubleshooting.
I would love to go the Oracle 12c and use its multitenant architecture, but I have 3rd party applications that don't yet support it. 11.2 might be our last release unless I can reduce costs. Consolidation is real and much needed, I believe why Oracle responded to the market with multitenancy.
But back to my first question about how many diskgroups to service a group of databases. What I hearing, and think I agree to, is that one data group will suffice because the ASM instance knows where to retrieve the data and waste will be reduced, as well as management.
I still need to do some ciphering and by no means have a final plan, but thank you all for your insights and contributions.

Best practice for development using REST API - OData

Hi All, I am new to REST. I am a developer who works mostly in server-side code using Visual Studio. Now that Microsoft is advocating to write code using REST API instead of server-side code or client side object model, I am trying to use REST API.
I googled and most of the example shows to write a code and put it on Content Editor/Script Editor. How to organize code and deploy to the staging/production in this scenario? Is there any Best Practice or example around this?
Regards,
Khushi

If you are writing code in aspx or cs it does not mean that you need to deploy it in the SharePoint server, it could be any other application running from your remote server. What I mean it you can use C# & Rest API to connect to SharePoint server.
REST API in SharePoint 2013 provides the developers with a simple standardized method of retrieving information from SharePoint and it can be used from any technology that is capable of sending standard HTTP requests.
Refer to the following blog that provide your more details about comparison of the major features of these programming choices/

Best practices for data entry online system

Hi all
I am(with a team of 4 members) going to build an online data entry system which may have approximately 30 screens. I am going to use Spring BlazeDS remoting to connect middleware.
Anyone could please suggest me some good practices to follow in flex side to do such a "DATA ENTRY" application.
The below points are some very few common best practices we need to follow while doing coding .But i am not sure how to achive them in flex side.
User experience (Probably i can get little info regarding this from my client)
Code maintanability
Code extendibility
memory and CPU optimization
Able to work with team members(Multiple checkouts)
Best framework
So i am looking for valueble suggestion from great minds.

There are two options, none of them very palatable:
1) One is to create a domain, and add the VM and your local box to it.
2) Stick to a workgroup, but have the same user name and password on both machines.

Best Practice for CTS_Project use in a Non-ChARM ECC6.0 System

We are on ECC6.0 and do not leverage Solution Manager to any extent. Over the years we have performed multiple technical upgrades but in many ways we are running our ECC6.0 solution using the same tools and approaches as we did back in R/3 3.1.
The future vision for us is to utilize CHARM to manage our ITIL-centric change process but we have to walk before we can run and are not yet ready to make that leap. Currently we are just beginning to leverage CTS_Projects in ECC as a grouping tool for transports but are still heavily tied to Excel-based "implementation plans". We would appreciate references or advice on best practices to follow with respect to the creation and use of the CTS_Projects in ECC.
Some specific questions:
#1 Is there merit in creating new CTS Projects for support activities each year? For example, we classify our support system changes as "Normal", "Emergency", and "Standard". These correspond to changes deployed on a periodic schedule, priority one changes deployed as soon as they are ready, and changes that are deemed to be "pre-approved" as they are low risk. Is there a benefit to create a new CTS_Project each year e.g. "2012 Emergencies", "2013 Emergencies" etc. or should we just create a CTS_Project "Emergencies" which stays open forever and then use the export time stamp as a selection criteria when we want to see what was moved in which year?
#2 We experienced significant system performance issues on export when we left the project intersections check on. There are many OSS notes about performance of this tool but in the end we opted to turn off this check. Does anyone use this functionality? Any reocmmendations?
Any other advice would be greatly appreciated.

Hi,
I created a project (JDeveloper) with local xsd-files and tried to delete and recreate them in the structure pane with references to a version on the application server. After reopening the project I deployed it successfully to the bpel server. The process is working fine, but in the structure pane there is no information about any of the xsds anymore and the payload in the variables there is an exception (problem building schema).
How does bpel know where to look for the xsd-files and how does the mapping still work?
This cannot be the way to do it correctly. Do I have a chance to rework an existing project or do I have to rebuild it from scratch in order to have all the references right?
Thanks for any clue.

Best practice for data persistance for monitoring without BAM

Greetings,
We are modeling a business process in a large organization using BPEL Process Manager. The key point is that business people needs to monitor the execution of the business process in several key sectors of the process execution as well as they need to get report information of the process.
To model this in our project, we decided to create a new Oracle Database Schema that is going to hold the information about the business process execution (we decided that because for this initial offering the customer is not buying BAM). In this context, the BPEL process is going to be sending this key information to the repository so business people can then view real time information about the process execution as well as historical information in form of reports.
The important issue here is, if there is a best practice to send the information to the Database Schema ? it could be just using single database adapters ? maybe using sensors sending the data using topics connections ?
Any help will be highly appreciated.
Thanks in advance.

hi..yes this suggestion is nice...first configure the sensors(activity or variable) ..then configure the sensor action as a JMS Topic which will in turn insert the data into a DB..Or when u configure the sensor action as a DB..then the data goes to Oracle Reports schema..if there is any chance of altering the DB..i mean if there is any chance by changing config files so that the data doesnt go to that Reports schema and goes to a custom schema created by any User....i dont know if it can b done...my problem is wen i m configuring the jms Topic for sensor actions..i see blank data coming..for sm reason or the other the data is not getting posted ...i have used a esb ..a routing service based on the schema which i am monitoring...can any1 help?

2K8 - Best practice for setting the DNS server list on a DC/DNS server for an interface

We have been referencing the article
"DNS: DNS servers on <adapter name> should include their own IP addresses on their interface lists of DNS servers"
http://technet.microsoft.com/en-us/library/dd378900%28WS.10%29.aspx but there are some parts that are a bit confusing. In particular is this statement
"The inclusion of its own IP address in the list of DNS servers improves performance and increases availability of DNS servers. However, if the DNS server is also a domain
controller and it points only to itself for name resolution, it can become an island and fail to replicate with other domain controllers. For this reason, use caution when configuring the loopback address on an adapter if the server is also a domain controller.
The loopback address should be configured only as a secondary or tertiary DNS server on a domain controller.”
The paragraph switches from using the term "its own IP address" to "loopback" address. This is confusing becasuse technically they are not the same. Loppback addresses are 127.0.0.1 through 127.255.255.255. The resolution section then
goes on and adds the "loopback address" 127.0.0.1 to the list of DNS servers for each interface.
In the past we always setup DCs to use their own IP address as the primary DNS server, not 127.0.0.1. Based on my experience and reading the article I am under the impression we could use the following setup.
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: 127.0.0.1
I guess the secondary and tertiary addresses could be swapped based on the article. Is there a document that provides clearer guidance on how to setup the DNS server list properly on Windows 2008 R2 DC/DNS servers? I have seen some other discussions
that talk about the pros and cons of using another DC/DNS as the Primary. MS should have clear guidance on this somewhere.

Actually, my suggestion, which seems to be the mostly agreed method, is:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
The tertiary more than likely won't be hit, (besides it being superfluous and the list will reset back to the first one) due to the client side resolver algorithm time out process, as I mentioned earlier. Here's a full explanation on how
it works and why:
This article discusses:
WINS NetBIOS, Browser Service, Disabling NetBIOS, & Direct Hosted SMB (DirectSMB).
The DNS Client Side Resolver algorithm.
If one DC or DNS goes down, does a client logon to another DC?

I agree with this proposed solution as well:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
One thing to note, in this configuration the Best Practice Analyzer will throw the error:
The network adapter Local Area Connection 2 does not list the loopback IP address as a DNS server, or it is configured as the first entry.
Even if you add the loopback address as a Tertiary DNS address the error will still appear. The only way I've seen this error eliminated is to add the loopback address as the second entry in DNS, so:
Primary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Secondary DNS: 127.0.0.1
Tertiary DNS: empty
I'm not comfortable not having the local DC/DNS address listed so I'm going with the solution Ace offers.
Opinion?
