My company is running an R-Studio Server Pro on a Red Hat Linix 6 platform (64bit) and a Teradata 14 RDBMS. When trying to connect via RJDBC, I get an error that seems to be well known in the forums, but the standard recipes for resolving the issues don't help. Here is how I connect to the Teradata DB:
drv = JDBC("com.teradata.jdbc.TeraDriver", classPath = "<path>/terajdbc4.jar:<path>/tdgssconfig.jar", identifier.quote = "'")
con = dbConnect(drv=drv,"jdbc:teradata://<DSN>/CHARSET=U
TF8,TMODE=TERA,SESSIONS=1", "<user>", "<pwd")
ret = dbGetQuery(con, "sel * from <table>")
I have searched the forums, and found several posts on such an error (e.g. https://forums.teradata.com/forum/analytics/connec
As you can see, this is not my case. The jars are in the proper place, and the Java class TdgssManager is present in the terajdbc4.jar. The R-function .classPath() also list them properly.
Some background information:
Can you please give me a hint what still could be wrong?
can you try to run the two classpath statements two times. I get sometimes the missing classpath message also. But usually it disapears after I run the class path statements a second time.
also I am using a different connection for the tdConnect
tdf <- td.data.frame("calendar")
my.stats <- td.stats(tdf,"year_of_calendar", c("cnt","min","max","mean"))
the system is the dsn name found in /etc/hosts not the full jdbc connection string.
I tested this with teradata studio and Teradata R15.0
I don't have R studio server available...
Just to revalidate - the classpath is refering the server path to the jdbc driver, not the local client path. correct?
I'm having the exact same problem, and adding the .jaddClassPath's twice does not help.
I'm using RJDBC 0.2-5, Teradata driver 15, and Java 1.6 on Ubuntu linux.
I do not want to use teradataR, as it is no longer supported.
