I'm using R/RStudio on CentOS platform. I need to see if the binary log file (/var/log/messages) contains further information regarding a graphics device plotting issue, but I cannot read it from within RStudio.
I cannot find any information on the community support troubleshooting pages. The Help Menu -> Diagnostics -> ... does not indicate a 'Show Log Files' option. Can someone advise how this file can be accessed, preferably from within RStudio?
By default /var/log/messages is not readable by all users, so the first thing you need to do is make it accessible to whatever user you're logged in as in RStudio. This question has details and ideas:
https://serverfault.com/questions/258827/what-is-the-most-secure-way-to-allow-a-user-read-access-to-a-log-file
Once your user account has permissions to /var/log/messages, you can use something like the following to show it in RStudio:
> readLines("/var/log/messages")
(You could also try file.edit("/var/log/messages") to open it in an editor buffer, but that is less likely to succeed.)

I need to upload a file to OneDrive, via the command line. This will be done through a batch file which is distributed to end users.
From searching on Stack Overflow, I find questions like this one which say that you need to register an app and create an app password, using Azure. I don't have the necessary permissions to do this in the organization where I work, nor can I do anything that requires an admin account. So I can't any install software - I have to use what comes with Windows 10. I can't use VBA either as that's blocked.
I've managed to download files from OneDrive without anything like that, using the process described here:
Open the URL in either of the browser.
Open Developer options using Ctrl+Shift+I.
Go to Network tab.
Now click on download. Saving file isn’t required. We only need the network activity while browser requests the file from the server.
A new entry will appear which would look like “download.aspx?…”.
Right click on that and Copy → Copy as cURL.
Paste the copied content directly in the terminal and append ‘--output file.extension’ to save the content in file.extension since
terminal isn’t capable of showing binary data.
Example:
curl https://xyz.sharepoint.com/personal/someting/_layouts/15/download.aspx?UniqueId=cefb6082%2D696e%2D4f23%2D8c7a%2
…. some long text ….

cucg=1’ --compressed --output file.extension
I tried to do something similar after clicking 'upload' on the browser, but didn't find anything useful when trying to filter the requests.
I found these two questions but there is no keyboard shortcut to upload, AFAICT. Also the end user will be uploading a file to a folder I've shared with them from my OneDrive. Opening Chrome or Edge as a minimised window is fine, but I can't just shove a window in their face which automatically clicks on things - they won't like that.
It's just occurred to me that I might be able to use an office application to Save As the file to the necessary onedrive folder, where the keyboard shortcuts are pretty stable, but have no idea how to achieve that via the command line.
The best and more secure way to accomplish this goal I think is going to be with the Rest API for OneDrive.

You still need a Azure AD App Registration (which your admin should be able to configure for you), to provide API access to services in Azure. Coding with the API is going to be far easier and less complicated, not to mention more versatile.
As we have below command to extract all the projects/reports from obiee12c analytics
exportServiceInstance( '/oraclehome/user_projects/domains/bi','mycompany.facility', '/workDir', '/scratch/exportDir')
This command provided extracts all metadata information of every projects and folders and report present in analytics as a archived bar file.Is there any other way were I can get metadata information of particular report or project which I need and not all the projects as a bar file or any?
OBIEE comes with several client tool with the "Catalog Manager" being the admin tool of choice for handling catalog-related tasks like yours. It exists as a GU and a command line both so you can also automate/script repetitive tasks like reporting on your reporting objects.
Have a look at the official documentation as it's too much text to just post into an answer here and you may come across things you want or need in there which go beyond your initial question here:
https://docs.oracle.com/middleware/12211/biee/BIESG/GUID-E804B1AF-B792-4929-BE47-33CA0F668715.htm#BIESG340
I you only need the reports you can export your reports folder directly from the catalog in OBI web interface or using "Catalog Manager" as suggested by #Chris.
For the repository you can connect Online to your server then from file -> Copy As
Note : exporting the service instance is used for environment migration, it's easier to move all what you need with one bar file (for example having DEV PROD environments).
I would like to add a link to a local file in confluence. Obviously this link would only work if the file is locally on the users computer. I understand that.
If I add the address like this :
file:///D:/dev/ngs-frontend/src/pages/myPage.html
The browser sends me to :
about:blank
If I try to add it with quotes like so :
"file:///D:/dev/ngs-frontend/src/pages/myPage.html"
..confluence crashes!
How is it possible in confluence?
As you mentioned when adding the web link in Confluence specifying the file using the file protocol (file:///) you might face the issue that it doesn't work.
Obviously this link would only work if the file is locally on the users computer.
This is not entirely true. If you open the developer tools you most likely will be getting the error "Not allowed to load local resource"
As measure of security the browser won't let you access files from a different origin, specially from the users computer (this would be a serious security risk). Only imagine if you could access the files in the Windows directory from the browser, you could break apart the operating system in no time (or steal user data).
This is explained in here
If you put the file in the same server Confluence is running, then this should work just fine. However I believe you can save time just adding the page as an attachment and loading it (Confluence is pretty decent at version controlling in case you want to modify the html file).
Hope this helps!
I want to know if this is doable and get some hints about how to achieve this.
I guess at least it would need a confirmation dialog to run the (possibly evil) macro.
I want to produce an OpenOffice document that will upload itself on save to a hardcoded URL.
Is it possible?
What are the rough steps to achieve this?
My guess is:
bind a macro to the save event
have that macro get the current file binary data
have it post this data to a URL
but before researching about how to do this I need to know if this can be done in the first place.
I don't believe you need a macro to do this, instead depending on your OS you can map a FTP or other type of protocol remotely.
For example in windows you can "Map" a FTP as a drive and this would do exactly the same thing as your describing, you open the file from the FTP and upon saving it will then be written to the remote server. FTP is just an example here, there are other platforms you can use.
If you are at all interested in this method then following the instructions below, otherwise disregard.
Mapping a Network Drive in Windows Vista and 7.
Click on Windows start orb and then click on "computer".
Click on map a network drive.
Map a network drive will then open a new dialog box where you can click "connect to a website"
Simply follow that easy to use wizard and click add a new network location (Choose a custom network location)
Type in your FTP address, including username and password.
Finally name your network location to whatever you want.
Just a suggestion, I really don't think you need any macro unless you plan on distributing these files to other people then yes, but they would need to install that macro/plugin on their open office since there is no way to encode the document itself with such features as far as I know.
I'm writing a script using Perl and Net::FTP, which is trying to upload a rather large file to the mainframe and I can't seem to get the primary/secondary allocations right.
I try to change them but it appears that, because the data sets are SMS-managed, they go to a different volume each time.
So I went looking the the quote site option which would (hopefully) lock the upload to a specific volume.
The current options I have are:
$ftp->site ("bl=10204 lr=170 rec=vb cy pri=100 sec=100")
and space is pretty tight on most volumes. However, I've located a volume with the required space but don't know how to specify that in the FTP options.
Is there a document somewhere detailing them? I couldn't find anything in the CommServer stuff nor did a Google search for ftp zos quote site turn up anything useful.
Alternatively, does anyone know the option to specify a fixed volume? Obviously I'd prefer the former since there may be other useful things in there but, at this point, I'd take the latter gratefully - I've darn near pulled out all my hair :-)
Log onto your mainframe's FTP using an interactive FTP program (e.g. FTP). Then type "quote help site" and you should get a good list of the options.
Just a little explanation... "site" is a command for the mainframe's FTP server. Typing "help" in front of it gets you help on the function. However, just typing "help site" will look for help on your FTP client (which probably never heard of the site command), so you have to pump the command to the server, which is what the "quote" command does.
BTW, your site command is asking for 100 primary and 100 secondary cylinders. That's a hefty chunk of DASD. Do you really need all that?
Good luck... let me know if you have any questions. I practically live on FTP on the mainframe and have written dozens (maybe hundreds) of Perl scripts to make things easier.
As a general FTP reference for z/os try Z/OS V1R7.0 Comm Svr: IP User's Guide and Commands.
Site commands can be found here.
Why not let SMS find the appropriate volume by using a DataClass appropriate for the file size?
How much hair did you start out with? Some can't afford to pull too much!
