So for the past couple of days, I've been trying to establish a connection between SAP BW and Microsoft PowerBI. I'm establishing the connection between the two systems using the driver (HDBODBC) provided in the HANA Suit.
Using the connection provided in PowerBI I was able to establish a connection between the two systems. The user used to create the connection was a DB level user created by our BASIS consultant. This use has sa access to the DB.
I want to stress on the fact that application level users couldn't connect to this so we had to create a DB level user and connect tot he DB Server of HANA instead of the Application Server of SAP BW.
The problem occurs when I try to browse and view data available in HANA queries, Composite Providers and Cubes.
I want to know if there is a configuration/authorization that has to be assigned in the application level to rectify this error?
Thanks in Advance

I'm struggling to connect my shiny application to one of the database we use in our company. I've succesfully connected to Azure / Mongo / SQL Server databases but now I've got a SAP SQL Anywhere 17 database to connect to.
Not surprisingly there's no specific connection to that database provided in the R Drivers (https://www.rstudio.com/products/drivers/).
Now I can solve this in two ways I believe, our IT department is convinced that a generic ODBC connection should work, or I have to get the specific SQL Anywhere drivers installed on my shiny app somehow.
For both solutions I can't find much online. If I search for generic ODBC connection the recommendations go to FreeTDS which is in the RODBC package, which then might not work together with Pool (according to what I've read).
Searching how to install specific drivers on a shiny application is also not bringing me much.
Try using
options(java.parameters="-Xmx8g")
library(RJDBC)
drv <- JDBC("com.microsoft.sqlserver.jdbc.SQLServerDriver", "drivers/jdbc/mssql-jdbc-8.4.1.jre8.jar", identifier.quote="`")
processingStart = Sys.time()
conn <- dbConnect(drv,
"jdbc:sqlserver://SERVER_NAME;databaseName=DATABASE_NAME",
user = "USER_NAME",
"PASSWORD"
)
I'm trying to connect to a SQL Server 2016 database in RStudio. I'm using RStudio on my laptop. I could remote in to the server and install RStudio there if it were absolutely necessary, but working locally has massive advantages so I would really prefer that if it were possible. Connection with the server goes through a VPN (FortiClient) that I have running on my laptop.
On this server, there are two SQL Server instances. One is a SQL Server 2012 edition, which is the default instance and hence not named - it used to be the only instance on this server. The other one is the 2016 edition. This instance was set up more recently in order to use the R integration capabilities new to SQL Server 2016. Because the server already had a default instance, this instance had to be named and it hence is called DEVR.
When I access the instances in SSMS and click 'Properties', the name of the default instance is DWH-ACC and the 2016 instance is called DWH-ACC\DEVR.
This is the code I'm running in RStudio to test my connection:
server <- "[IP-ADDRESS]\\DWH-ACC\\DEVR"
databaseName <- "Database"
user <- "user"
pwd <- "password"
sqlShareDir <- "C:\\Dir"
sqlWait <- TRUE
sqlConsoleOutput <- FALSE
sampleDataQuery <- "SELECT TOP 10 FROM [dbo].[Table]"
cc <- RxInSqlServer(server = server, databaseName = databaseName, user = user, password = pwd, shareDir = sqlShareDir, wait = sqlWait, consoleOutput = sqlConsoleOutput)
rxSetComputeContext(cc)
inDataSource <- RxSqlServerData(sqlQuery = sampleDataQuery, server=server, databaseName=databaseName, user=user, password=pwd, stringsAsFactors=TRUE, rowsPerRead=500)
rxGetVarInfo(data = inDataSource)
I've tried several options for the server specification, among which [IP-ADDRESS]\\DEVR and [IP-ADDRESS]/DEVR, which both do not work either. This is the error I get when I run the code:
[Microsoft][ODBC SQL Server Driver][DBNETLIB]The SQL-Server does not exist or permission has been denied.
Could not open data source.
ODBC Error in SQLDisconnect
(Message translated from Dutch, by the way - this may not be the exact error text in the English version of the software)
When I try simply the IP address as my server connection string, I get a different error that seems to indicate it is able to find the instance (the 2012 one, i.e. the wrong one) but not able to process the query.
[Microsoft][ODBC-stuurprogrammabeheer] Fout in functievolgorde
I'm not sure how to translate this one, but it seems to be related to ODBC-drivers and says "error in function order". Anyway, this error is unrelated and I don't need it solved or explained, it simply goes to show that R does seem to be able to connect to the default instance but not to the newer, named one.
Enable Implied Authentication for Launchpad Accounts
Specifically navigate to the User Account from the Control Panel and you'll see the SQLR UserGroup with 20 accounts.
Permission these on the Server and DB Table with write access.
That should see you right. Good luck
You could create a ODBC connection in your local instance. A tutorial on creating ODBC connections can be found here. Background about the different types of SQL Server ODBC connections can be found here.
The ODBC connection should be able to distinguish between the the different SQL Server instances.
For me the main advantage in using ODBC connections is that I don't have to store database passwords inside/near my R scripts.
In R/Rstudio you can connect to the SQL Server instance via the ODBC channel. A tutorial on ODBC channels and RevoScaleR: link.
Other packages in R also provide possibilities to connect to ODBC connections, for instance: RODBC, dplyr.
Hi Oracle DB guys out there, Is there a way to propagate DML changes in database to some MQ server(Kafka in my case). I have read about following but coulnt find any concrete implementation
oracle streams:- which are for database to database replication
oracle strams AQ:- for integration with MQ clients
GoldenGate: which we cannot use because of cost
I want to monitor oracle ebs(11i) & oracle db(11g) simultaneously during load test through dynatrace.
Oracle EBS architecture
I know we can monitor oracle db using dynatrace but did not find how to Identify what areas or modules (e.g. Order Management, Sales, Finance, Shipping) a particular work flow/user request touches during the load test?
I found that using DC RUM we can capture the metrics for Form Server. Apart from this I also want to monitor Concurrent processing server. Is it possible using dynatrace or not?
With Dynatrace DC RUM you may choose one of two approaches of monitoring EBS performance.
First - DC RUM using agentless technology, captures network traffic between all servers and clients and as result provides you with information on performance, usage and availability details. Additionally for most popular network protocols including the ones used during communication with Oracle database, Oracle Forms servers and web servers it’s possible to use analyzers, that provides deeper performance insights. For example with Oracle Forms analyzer applied for EBS monitoring DC RUM is decoding all interactions between user and oracle forms reporting user names, form names, control names and identifying EBS module name. For Oracle Database traffic it reports performance down to single query execution including SQL, database schema and user name. Answering your question it allows monitoring of Oracle EBS and Oracle DB simultaneously.
Second one – Enterprise Synthetic allows you to create synthetic tests for key transactions in EBS. This way for example you may track the performance of whole creating sales order transaction.
DC RUM is intended to constant, systematic application performance monitoring. However if you have it in your company it’s also perfect tool to evaluate the results of the load tests performed on EBS.
Working on Progress 9.1E on a Windows box. We've got a standard 4GL GUI application up and running which connects to a series of personal databases running on the same box. It's sort of like a big graphical catalogue application with ordering capabilities.
Anyhow, we're looking to run a .Net application on the same box and Progress supplies a Merant ODBC driver along with it's runtime.
My question is, can I have the 4GL GUI client application up and running and connected to the Progress databases while at the same time connecting and running the .Net application which connects via an OBDC System DSN to the same databases?
These "personal" databases are traditionally single user, but I'm wondering (or have heard through rumours) that you can actually run an ODBC client in addition to a 4GL client on the same box at the same time.
Truth to this?
You can run both a 4GL client and an ODBC client, but you can't run them both single user at the same time. You'll need to start a server for each of the DBs you want concurrent access to. You can run the server process on the same machine, if you have the licence, if that helps.
