Changing library location - rmysql

So I'm relatively new to using r-studio and I'm having a problem installing RMySQL.
I'm running RStudio 0.98.501 and R 3.0.2 and trying to connect R to a database. However, whenever I try to install RMySQL I get the error message "package ‘RMySQL’ is not available (for R version 3.0.2)". When I searched I found this thread: http://r.789695.n4.nabble.com/RMySQL-with-Windows-7-td4684805.html which explains how I could be downloading packages to Program Files. I checked using the .libPaths() function and this was confirmed ("C:/Program Files/R/R-3.0.2/library"). I guess my question is how do I change the library path so that I can install RMySQL? Or am I going about this all wrong?

Try to follow the instructions here posted here.
Basically what you have to do is:
install MySQL from the Oracle homepage
install RTools
change your system variable "MYSQL_HOME" to match your MySQL installation
(in some cases ibmysql.dll which is part of your MySQL installation had to be copied from lib folder to bin folder so it could be found)
That should (hopefully) do the trick although I did not stumble upon any remark stating RMySQL installation (especially under Windows) is easy.

requested datatype filelists not available in yum update

In order to patch RedHat 7 machines to version 7.9, I've created an RPM repository with RPMs extracted from a DVD.iso file of the patch (example source guide), and updated said machines using yum.
The patch has succeeded with many of the machines (RHEL 7.7 only), but the rest (7.0, 7.2 and some 7.7 as well) have failed the with the following error:
Error: requested datatype filelists not available
I've also tried to gradualize the process and patch the 7.0 and 7.2 ones to 7.7 first by the same process, but yielded the same result. I've made sure I got each and every file in the Packages folder.
It is rather puzzling for me that some succeed and some fail, especially those with the same version. But I'm assuming they were created differently as I don't have the information to say otherwise. So my best direction would be to go by the error.
In this github post, lr1980 says:
https://blog.packagecloud.io/eng/2015/07/20/yum-repository-internals/
this means the "filelists.xml.gz" is missing on repo => it's a packager.io problem
Indeed, browsing my repository's repodata folder reveals only other.xml.gz and primary.xml.gz files, which are also the only files pointed to in the repomd.xml.
I've tried uploading the filelists.xml.gz file from the dvd.iso and reindexing, but it gets removed (admittedly am not familiar with this area of knowledge.. at all). What does "it's a packager.io problem" mean?
How can I force the repo to have such a file, assuming that's what I need? Or what can I do to solve this issue otherwise?
Many thanks

nodeclipse editbox plugin - unable to install

I have updated eclipse to 4.10 (2018-12/R), the cpp package
Running under ubuntu 18.04.
I tried to add nodeclipse editbox using the marketplace, but it cannot find the plugin.
Then tried the option help-install New Software, adding the repository provided in the github site (https://github.com/Nodeclipse/EditBox), as
http://nodeclipse.github.io/dev.updates/editbox-1.0.0/
But I always get this error:
An error occurred while collecting items to be installed
session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Unable to read repository at http://nodeclipse.github.io/dev.updates/editbox-1.0.0/plugins/pm.eclipse.editbox_1.0.0.201804021412.jar.
Connection reset
I have searched for the whole morning, and cannot find any reference to the possible cause of this error.
Any pointer will be appreciated
OK, looks like I solved it. Recording it here in case others come looking.
The problem was in the server that cut the file download midway.
So using the information in the error message, I was able to download and install directly the plugin. I did:
cd /opt/eclipse/plugins - To get the download directly into the plugin folder
Then used wget to download the folder directly:
wget http://nodeclipse.github.io/dev.updates/editbox-1.0.0/plugins/pm.eclipse.editbox_1.0.0.201804021412.jar
Restarted eclipse, and voila! It was working.
Simpler than I thougth.

Why the installing process of R package "RODBC" in "R CMD INSTALL" can't find ODBC driver manager?

I am trying to connect to an Vertica DB from R using "RODBC" package. Also, the machine I am using is an remote server which doesn't have direct internet access so I basically "transfer" all source files from my local to the remote server to build the system. So, in order to give you an clear context, I am listing all my steps in attending of installing "RODBC" package below:
Step1 - I downloaded the RODBC_1.3-13.tar.gz source file for RODBC and then tried to directly install it with "R CMD INSTALL". However, I encountered error as "ODBC headers sql.h and sqlext.h not found".
Step2 - After a few researches, I found that the installation of "unixodbc-dev" would potentially solve this issue. Therefore, I downloaded all needed dependencies for "unixodbc-dev" and transferred them to the server. As you can see the list:
Therefore, I also successfully installed "unixodbc-dev":
However, another error message appears when I tried to re-install the "RODBC" using "sudo R CMD INSTALL /home/mli/RODBC_1.3-13.tar.gz" in which it returns error "no ODBC driver manager found":
As the message indicates, the installation program can't locate my ODBC driver manager. So, I downloaded "vertica-client-7.2.3-0.x86_64.tar.gz" and unzipped it on the server:
So, now my question is how can I customize the "R CMD INSTALL" command say, using some parameter handles to direct the installation program to locate the driver manager? Or am I trying this in a right direction? Please let me know. Any help would be really appreciated!!! :)
ADDITION:
I have also tried it with JDBC in which the I successfully loaded the "RJDBC" package in R and used the JDBC driver from vertica-client-7.2.3-0.x86_64.tar.gz. Also, I have already had "rJava" installed. However, I have still got an error when I tried to make the connection. I am listing my result below:
I successfully installed the "RJDBC" with "$R CMD INSTALL RJDBC_0.2-5.tar.gz --library=/usr/local/lib/R/site-library/" and then I tried the following scripts in R. All the lines are successfully executed except on the line 16:
Based on the error message, I assumed the version of the JDBC driver that I was using is too new for the Vertica server. So, I was trying to use an older version JDBC driver instead, like the "vertica-jdk5-6.1.0-0.jar" which I have downloaded from this link:http://www.java2s.com/Code/Jar/v/Downloadverticajdk56100jar.htm
So, I moved the file "vertica-jdk5-6.1.0-0.jar" to my home directory on the server and then changed the JDBC driver path in the R script:
As you can see, it still returns error "FATAL: Unsupported frontend protocol 3.6: server supports 3.0 to 3.5". Am I doing it right? Or is there an issue with the new driver that I downloaded? How can make it works? Please, any help will be really appreciated! Thanks!!!
A few things:
First, just do sudo apt-get install r-cran-rodbc. The package was created (by yours truly) in no small part because dealing with unixODBC or iODBC is not fun. But even once you have that, you still need the ODBC driver for Linux from Vertica. And that part is filly.
Second, I just did something similar the other day but just used JDBC, which worked. You do of course need sudo apt-get install r-cran-rjava which has its own can of worms (but I already mentioned Java...) Still, maybe try that instead?
Third, you can cheat and just use psql pointed to the Vertica port (usually one above the PostgreSQL port).

SQLDeveloper not starting

When i try to start SQLDeveloper, it is giving me the following error in command prompt:
Error: This product requires a Java(TM) Platform 5.0 runtime.
You are using 1.4.2-b28 from C:\j2sdk1.4.2\jre
But my JAVA_HOME is set to java 6
JAVA_HOME=C:\Program Files\Java\jdk1.6.0_32
Can anyone explain what exactly to do to resolve this?
Oracle SQL Developer uses a configuration file named products.conf which is situated at your roaming directory.
If you are using Windows 7 then the directory path will be:
C:\Users\\AppData\Roaming\sqldeveloper\1.0.0.0.0
Delete whole sqldeveloper directory from C:\Users\\AppData\Roaming\
Re run sqldeveloper executable, this will prompt for jdk home
Select jdk home. i.e C:\Program Files\Java\jdk1.7.0_55
Enjoy!
In my case i had 2 folders under C:\Users\username\AppData\Roaming\
sqldeveloper
SQL developer
after removing both of them and launching installation dir\sqldeveloper\sqldeveloper\bin\sqldeveloper64.exe it worked.
True acknowledgement / attribution belongs to Vishal at the following URL:
http://vishalorcl.blogspot.com/2012/12/sql-developer-from-11201-client-software.html. It describes in detail how to resolve this problem. From the page:
I am running Oracle 11g version of SQLDeveloper. I have same problem
noted above, after fresh install of Oracle. The summary is that
SQLDeveloper seems to require the Java 32-bit JDK.
Install 32-bit jdk V7 from Oracle:
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
There is a sqldeveloper.conf file located in
C:\app\UserName\product\11.2.0\dbhome_1\sqldeveloper\sqldeveloper\bin
In the file change pathname within the line at end of file:
SetJavaHome C:\app\admin\product\11.2.0\client_1\jdk
To point to pathname of the jdk install directory; also sometimes
known as JAVA_HOME.
I had this problem too!
you should go to: C:\Users-your user name-\AppData\Roaming\sqldeveloper-version of your sql developer-
there is a file named product.conf there. Right click on it and edit it with notepad in the document change the address of java home and save it.
Done!
In my case, none of the other suggestions worked. Instead, I moved the installation directory from
c:\sqldeveloper
to
anything else
And things worked again. Perhaps, some Windows registry value got broken in an unfixable way...
I don't think SQLDeveloper uses the environment variable. There should be a .conf file that contains a reference to the JDK directory.
I solved this by deleting the folder /home/USERNAME/.sqldeveloper
After that, I started SQLDeveloper and without typing anything, it found the right java-version and started without complaining :-)
So, if you don't want to delete the whole folder, maybe search there for the file which defines the java-version :-)
edit: just found that:
"Type the full pathname of a J2SE installation (or Ctrl-C to quit), the path
will be stored in ~/.sqldeveloper/jdk"
check the version of java that you are installing to you Pc the error show that you are using 4 so uninstall the java that you have then install a new one that is version higher than 5
Removing the instances from the registry worked for me.

Installing Orafce.sql 3.0 in Windows 7

As mention in Orafce Install.orafunc:
..install Orafce functions in the database, either run the orafce.sql script using the pgAdmin SQL tool..
I tried running the orafce--3.0.sql in pgAdmin sql editor. This give me error
ERROR: could not access file "MODULE_PATHNAME": No such file or directory.
What do you mean by module path?
Installed program:
strawberry perl with DBD::Oracle
postgresql 9.3
pgAdmin III
Not fully installed:
ora2pg
I tried installing ora2pg...with a problem.
H:\PostgreSQL\ora2pg-12.1>perl makefile.pl
Unparsable version '' for prerequisite DBD::Oracle at makefile.pl line 553
Generating a dmake-style Makefile
Writing Makefile for Ora2Pg
Writing MYMETA.yml and MYMETA.json
Done...
H:\PostgreSQL\ora2pg-12.1>dmake && dmake install

Appending installation info to C:\strawberry\perl\lib/perllocal.pod
dmake: Warning: -- Target [install] was made but the time stamp has not been up
dated.
Suggested Solution:
I downloaded a copy of orafce from okbob github
Unzip the file to folder D:/Postgresql/orafce-master
I copy only the following files
orafce--unpackaged--3.0.6.sql
orafce--3.0.6.sql
orafce.control
to folder C:\Program Files\PostgreSQL\9.3\share\extension
Then I try running this command in pgAdmin III sql tools.
CREATE EXTENSION orafce;
I received this Warning and Error.
[WARNING ] CREATE EXTENSION orafce
ERROR: syntax error in file "C:/Program Files/PostgreSQL/9.3/share/extension/orafce.control" line 1, near end of line
I checked orafce.control content. It has this config.
# intarray extension
comment = 'Functions and operators that emulate a subset of functions and packages from the Oracle RDBMS'
default_version = '3.0.6'
module_pathname = '$libdir/orafunc'
relocatable = false`
I can't pass to this wall. What seems the problem?
So, you are working with source raw files. You should to compile these files first - and later you can use it. It is relative simply on Unix like platforms, where C compiler is usually available, and pretty hard on MS Windows, where you have to install C compiler first.
I afraid so we lost pgFoundry archive, where was orafce precompiled and packed.
Almost all Linux distributions support orafce directly - and you can install it without compilation from repositories.
see http://wiki.postgresql.org/wiki/Building_and_Installing_PostgreSQL_Extension_Modules
$libdir is symbol, that is used for PostgreSQL extensions directory. It can be different for any platform - and it is replaced inside compilation stage by actual value. MODULE_PATHNAME has similar meaning. In compilation stage is replaced by valid actual path to library with compiled code.
I am sorry - we don't provide a compiled files - mainly due high risk for MS Windows. We have no forces, and tools to maintain all Win safely. In this moment, you can:
try to contact someone who use orafce for windows for backup of orafce installers
try to compile this extension by self (Microsoft Visual Studio Express edition is free and downloadable on internet).
other possibility is migrate database server to Linux - almost all database maintenance and usage is more simply and more robust there (due missing viruses, antiviruses and less resource requests). The Linux is primary platform for Oracle too.
