I am not seeing goldengate's "replication statistics" on AWR report - gg and oracle version is 19. Does anything need to be done to be able to see gg replication stats on awr report?

I have updated my windows and R cannot run, and hence neither can R studio. When I run R GUI it just freezes and is unresponsive. I have allowed chromium exemption to the firewall
I am on Windows Insider program and has just updated to
Windows 10 Home, Insider Preview
Evaluation Copy.Build 20190.rs_prerelease.200807-1609
Note that R GUI freezes and then shuts down on its own, so maybe the problem is R GUI and not R Studio.
I get the following errors on R studio.
This site can’t be reached
127.0.0.1 refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
Cannot Connect to R
RStudio can't establish a connection to R. This usually indicates one of the following:
The R session is taking an unusually long time to start, perhaps because of slow operations in startup scripts or slow network drive access.
RStudio is unable to communicate with R over a local network port, possibly because of firewall restrictions or anti-virus software.
Please try the following:
If you've customized R session creation by creating an R profile (e.g. located at ~/.Rprofile), consider temporarily removing it.
If you are using a firewall or antivirus software which guards access to local network ports, add an exclusion for the RStudio and rsession executables.
Run RGui, R.app, or R in a terminal to ensure that R itself starts up correctly.

Troubleshooting RStudio Startup
This has been fixed with Windows 10 Insider Preview Build 20201 (released on August 26, 2020 in the Dev channel).The previous two builds were missing 64-bit APIs required by the prebuilt version of R.
Same issue.
Rollback to the previous version solves the problem.
I think it is about the update of the graphic features of Windows.
Here is what Microsoft said in the build 20190 changelog:
Improved Graphics Settings experience
While this isn’t a new feature all together, we have made significant changes based on customer feedback that will benefit our customers’ Graphics Settings experience. We have made the following improvements:
We’ve updated the Graphics Settings to allow users to specify a default high performance GPU.
We’ve updated the Graphics Settings to allow users to pick a specific GPU on a per application basis.
I am trying to connect R to Bigquery using bigrquery package and dplyr. Below is the sample code:
library(bigrquery)
project <- "fantastic-voyage-389" # put your project ID here
sql <- "SELECT year, month, day, weight_pounds FROM [publicdata:samples.natality] LIMIT 5"
query_exec(sql, project = project)
R asks me to cache OAuth between sessions, and it brings me to the browser session where it asks me the permission for view and manage my data in bigquery. Once I clicked yes, the browser says 'authentication completed'. In the meantime, however, the Rstudio crashs and says R has a fatal error.
my bigrquery package version is 0.1.0, and Rstudio 0.99.486
Does anyone have same experience before?
The solution was to delete tokens cached on disk by the httr library's OAuth2.0 functionality.
If this issue continues to occur (ie. reset_access_cred() doesn't work), a manual fix like this is clearly undesirable, and an issue should be opened with the maintainers of httr or bigrquery, depending on what's likely at fault.
While trying to integrate R Studio with SQL Server 2016 I am getting following error:
Unable to launch runtime for 'R' script. Please check the configuration of the 'R' runtime.
As suggested on different sites it is advised to install "%programfiles%\RRO\RRO-3.2.2-for-RRE-7.5.0\R-3.2.2\library\RevoScaleR\rxLibs\x64\RegisterRExt.exe" /install.
But I have already installed R studio and not able to find the path specified.
R Services for SQL 2016 is a new offering from Microsoft - who purchased Revolution Analytics about a year ago. This is the first major result of that.
SQL Server 2016 is in (CTP - community technical preview), so not really finished (although you can download and use a version that will expire after about 6 months). Also a lot of the docs are incomplete and there are probably a fair amount of bugs. However it has been long announced that it will include "R Services for SQL 2016", which is based on the Revolution R Engine. In order to use that you have to
Install SQL Server 2016 CTP as usual.
Install the "Advanced Analytics Extensions" from the setup.exe program (see https://msdn.microsoft.com/en-us/library/mt590808.aspx)
Obtain the appropriate RevoScaleR packages (there are two) and install them, one your client, and one on the machine running SQL 2016. They are described here: https://msdn.microsoft.com/en-us/library/mt604883.aspx
Then to test it you can follow the instructions here: https://msdn.microsoft.com/en-us/library/mt590808.aspx
Good luck with it, but remember it is still in pre-release development and testing, so problems are to be expected.
Does anybody knows if it's possible to interface Hadoop with R / Rstudio ? If yes, HOW?
I have some hive's table and I'd like to accès them with R / Rstudio and within 'shiny' make a visual restitution (graphs etc...).
I would appreciate any help (ideas, code examples ...).
Try the package dplyr.hive.spark. The docs are still a bit more geared towards spark, but I tested it against Hive with the latest HDP sandbox and things were going smoothly. If you give it a try please report any problems.
If you just want to access hive tables on HDFS, you can use the RJDBC package and a JDBC connection (explained here: https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-JDBC). Then you can use RJDBC just like you would for a relational database except that it might launch some map/reduce jobs on your cluster to execute.
I am working on Cognos 10.2 and while working on Framework Manager I've successfully created a Data model using MS SQL Server, I deploy the package successfully but when I check the same on IBM Cognos Business Intelligence it does not show me anything inside the Package (No Data Source and No Query Object).
Requesting to help me.
You likely didn't include anything within the Package in Framework Manager.
Right click on package, choose "Edit Definition". You will see all of the layers of the model; ensure that the final (presentation) layer has a green check next to it and not a red X.
