Update ROracle
Hola, ¿alguien sabe como actualizar un campo de oracle desde R con el paquete ROracle? Aquí el problema es el tipo de dato de la tabla, el cual no puede cambiar, es clob. Tampoco el paquete de R puede ser otro. Necesito poner un texto muy grande.
He buscado en google he intentado con stored procedure y no funciona. Se trata de un proceso que debe quedar automatizado.
Muchas gracias

CLOB handling in ActiveRecord 1.14.2
We recently switched to Rails 1.1.2, which includes the latest version
of ActiveRecord.
This version seems to have introduced an error with the handling of
non-binary large objects.
The OCI adapter in 1.13.2 seemed to have treated CLOB and BLOB
identically. The new Oracle adapter distinguishes between the two types
and gives CLOB a type of :text, where as BLOB are :binary

ROracle/DBI problem with dbExecStatement on RH Linux
Hi,
first thanks to Sunny Ho (and David James for the pointer) for resolving
the problem of the empty rows returned from ROracle.
However, I have a problem still:

> ora <- dbDriver("Oracle")
> con <- dbConnect(ora, user = USER, password = PWD, dbname = DBNAME)
> rs <- dbExecStatement(con, "select * from USER_TABLES")

OCFS supporting CLOB & XML data type
Hello,
I have been searching for it but could not find anything on Oracle different
servers.
Maybe someone here will be able to answer this question :
Are CLOB and SYS.XML data type supported by OCFS?
We need to migrate a 9.2.0.4 Windows Database having these data types to a
9.2.0.4 Linux Real Application Cluster with OCFS. This could cause an issue.
Thanks in advance

DBI/ROracle for remote database connection ?
Hello,
I have installed the ROracle and DBI packages, and I want to
access an Oracle database that is not on the same machine
as the one I am running R on.
I can access the database remotely with perl DBI and Java JDBC.
Does anyone know if this is possible using R DBI/ROracle ? I
have looked through the documentation and also tried to guess
at things which might work, but with no success.

What's the trick for using CLOB values (Oracle)?
I''ve got a bunch of fairly large values (30kb each) I''m trying to insert
into a CLOB column in my Oracle(10g) model. Since Rails is trying to
create a typical insert statement with the entire value, this is causing
a problem. Is there a trick I need to know to make this work, or am I
out of luck?
Thanks!

Core dump using DBI/ROracle

Has anyone seen this problem before, and does anyone have a solution?

[PATCH] ia64/pv_ops: paravirtualized istruction checker.
This patch implements a checker to detect instructions which
should be paravirtualized instead of direct writing raw instruction.
This patch does rough check so that it doesn't fully cover all cases,
but it can detects most cases of paravirtualization breakage of hand
written assembly codes.
