I created a worksheet yesterday. I have not made any changes to the configurations but today my graph is not being displayed.
However, if I hover over the worksheet name it shows me a preview of the graph I have created.
How do I make it show in the main window?
This is what solved the problemm, after speaking to Tableau support:
ODBC drivers (what I was using to connect to my database) are possible to use but not supported by Tableau.
Changing to a Microsoft SQL Server Driver solved the problem. Drivers can be found here:
https://www.tableau.com/support/drivers
Please check if your data is still available.. The Preview is coming from a cache of the workbook..
I have just experienced this behavior. The problem, in my case, was that I had built a "Set" that required a connection to the Tableau Server, and that connection had not been made when I opened the workbook.
Check to make sure that you are signed in to your Tableau Server from your workbook.
If that is not the problem, check each of your filters. Remove them and add them back, one by one. After the problem filter is removed, the worksheet will render normally. Then it is just a matter of fixing the filter.

Unfortunately, I made a change to the Jupyter Lab settings recently. Jupyter had never been able to access the remote R help server. Usually this was never an issue because most help files are displayed in Jupyter. The way help is called on a function or method is typing: ?question. The "question" being the name of an R function or method. Ex. ?plot
Infrequently one of the R packages will not list its help in Jupyter and instead try to open the remote R help server. This has never worked in the past. The tab for a remote server never opened. This has never really been an issue until recently. Recently I decided to "fix" this issue and spent a good deal of time looking up the solution. I made this "fix" and Jupyter began working properly to open the remote R help server. But the fix is a problem that is way too obnoxious.
Each time I type the question mark in Jupyter, Jupyter causes the browser to open a new tab for the remote R help server. It is impossible to type fast enough after typing typing the ?. Once the ? is typed, the typing is interupted while the browser opens a new R server help website. As soon as returning to the typing, another browser tab opens and interrupts the typing .
It is impossible to finish typing the name of a function after the ? without having multiple interruptions to the typing while multiple new windows are opened in the browser at the R help server website. By the time I've finished typing: ?ppp, there will the 5 interruptions and new browser tabs opened. If I typed slowly, there may be 10 - 12 interruptions and 10 new tabs opened at the R help server.
How to prevent Jupyter from trying to access the remote R help server every time the ? is typed when looking up a description of a function? How to get back to that happy place I had before I'd made whatever change that caused this nightmare to happen?
Solved my own question.
This issue had nothing to do with R. I assumed I had changed a configuration in R, but that was not the case. This was an issue I had caused when I had changed a setting in Jupyter lab.
I can say with certainty this issue was definitely caused when I changed the "Contextual Help" setting under the Commands tab in Jupyter. This setting is related to the Contextual Help selection found under the Help tab. And this setting was causing multiple R help server tabs to open in the browser after I typed: ?
Upon rediscovering this Jupyter setting today I recalling that I had been down this path before. I selected "Contextual Help". Jupyter auto restarted and the issue went away. I can gladly say that I can perform search again for the description of an R function: Ex ?plot ,and receive the description of this function within Jupyter the same as before. I no longer have the issue of the browser opening or multiple new tabs at the remote R help server after typing ?
Finally I need to change my current smartphone with firefox OS on it, due to some problems with the speaker.
Anyway I would like to backup not only the contacts, but also the messages (sms).
I found this great tutorial and the work of laenion http://digitalimagecorp.de/flatpress/?x=cat:8? and was able to retrieve the sqlite database of the messages.
Anyway laenion Exporter http://digitalimagecorp.de/software/firefox-os-data-exporter/ffosexporter.html? is only exporting the last messages from each thread, but I want to have a full backup.
Now I started reading in the file with his recommendation of the Firefox Storage Manager. Now it happens, that I can read out 2351 entries and then the conversion stops. However, if I delete some rows and do a restart it loads additional entries up to 2351 again.
Now I am wondering, is there a value in the about:config on how to extend the keys to be converted? Or is there anything else I am doing wrong? Why is the storage manager not reading in the complete database?
Thanks for any hint on how to solve it. Unfortunately I was not able to open the database in a readable style with any other program.
I am using SQL Developer 4.0.0.13 to connect to Oracle 11g DB. Now I have a package that I need to update its body, I open the package body in the editor, do my change then
1) right click compile
2) right click compile for debug
3) save (ctrl+s)
For all the above the new changes are not saved... When I close the package body editor and open it again I don't find my changes. I tried closing the app and opening it again but nothing helped... Any ideas??? It seems it caches or something like that.
Update
I tried updating it from a peer's machine, which worked fine... It seems the problem is in my version... By the way it was working well before.
Update
Same happens if try to edit any database entity (function/procedure/...).
I figured out the reason, I just needed to put the schema name as a prefix to the package body ....... but the weird thing is that the SQL developer didn't complain, It just printed a message 'compiled'
I've been using meteorjs for quite a while now on linux. But when I installed using the relatively new windows installer, I saw that the most basic example doesn't work on properly on my computer - win7.
The example is at: https://www.meteor.com/try/4
which runs perfectly on my ububtu, but on my windows - I see that no information is inserted into the db and all changes I make (add new "tasks") are only local to that page, and other tabs I opened were also local, and there was no "reactivity" (no information was shared between different pages).
I tried to troubleshoot it in some ways:
I made sure that MONGO_URL is not set, and then I set MONGO_URL to another db, and saw that even though that db reported "connection accepted", the oplog nor the collection updated (tasks) have any new information.
Tried different kinds of browsers (chrome, firefox). Both are latest in version.
See no errors in chrome console.
I am assuming that all writes are made to minimongo, which doesn't pass them on.
Is this somehow a known issue?
Any suggestions?
A few things you can try:
uninstall meteor & any separate instance of mongo (including cmd aliases). download a fresh copy & install. Create a new project in a new folder. If the DB had some weird bugged lock on it, this is sure to fix it.
download robomongo (or use meteor mongo) to insert a new doc & see if it sticks. If it does, you know mongo isn't the problem.
Check that autopublish and insecure are installed. If they are, when you complete step 2 you should see a new doc in the app. If you do, then the DB can communicate to the app, so the problem has to be with the client-side saving to DB. Try a meteor method instead of a direct insert. If you don't see a new doc, then the data from the DB can't reach your client, which means your firewall (yes, it can screw up localhost requests, too) is to blame. Turn it off, make sure ports 3000 & 3001 (mongo) are allowed full access & that it doesn't do anything wonky with websockets.
I would try re-installing Visual Studio 2012 and Python 2.6/2.7, then re-installing Node and then Meteor.
I have been given an ad hoc reporting tool from another individual that has successfully deployed it to the field. He uses Web Logic servers and an Oracle database.
I tried to deploy the same application in my local environment (WAS 7 and Oracle). The first report runs flawlessly. However, when I run the second (or third or fourth) report, I get a very strange error: the second report is appended to the first report.
There is nothing in the code to account for this. This problem can be temporarily solved by stopping and starting the servers every time a report is run (obviously not a real solution). I think this has something to do with data sources and cached information. I then took a step back and tried to deploy it to a Tomcat server. It works perfectly, just like it does in the field. So my question is: are there any known issues between WAS 7 and Oracle 11g that could be causing this kind of problem? Any information would be very helpful.
Please ask about any specifics you may want to know and I will do my best to provide that information.
Thank you for your time.
EDIT: For anyone else looking into this, the problem was due to an incompatibility with the proprietary Oracle calls and Websphere. Once the application was edited to use only JDBC calls, everything works perfectly. Thanks.
This ended up being a incompatibility with using proprietary Oracle calls and Websphere. It was fixed by changing all of proprietary call to normal JDBC calls.
