I am a beginner user of neo4j. I am trying to export a simple graph in .graphml format in order to be able to visualize it in Gephi. Even though the apoc procedures seem to be successfully installed, a command like CALL apoc.export.graphml.all("C:/path/to/folder/file.graphml",{}) generates the following error:
apoc.export.graphml.all is not available due to having restricted
access rights, check configuration*.
I tried to modify the neo4j.conf file (which I copied and pasted into the conf folder of the default graph database folder in Documents) adding dbms.security.procedures.unrestricted=apoc, shutting down and restarting neo4j with no success.
I am using Windows 10 and I have installed the NEO4J 3.2.1 Community Edition version (installer version). Any help appreciated.
I tried to modify the "neo4j.conf" file (which I copied and pasted
into the conf folder of the default graph database folder in
Documents) adding "dbms.security.procedures.unrestricted=apoc.*",
shutting down and restarting neo4j with no success.
According the documentation, the correct file location of neo4j.conf file for Windows installations is %APPDATA%\Neo4j Community Edition\neo4j.conf.
So edit the above file and put into it the line dbms.security.procedures.unrestricted=apoc.*".

I have Microsoft Office Professional Plus 2019 and Access database engine both 64-bit installed on my machine and was trying to import a CSV file to Analysis Services Tabular project. However keep getting the error message shown below.
"Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: The Microsoft Access database engine cannot open or write to the file 'BatchInfo.csv'. It is already opened exclusively by another user, or you need permission to view and write its data.; 3051."
Any help is appreciated please.
Either you or someone else has the file open. Sometimes you have to completely close out of the program that created the file, or the last program used to read, write, or save the file.
If it's something on your computer, you may be able to find what has it opened with the Process Explorer tool. Install it, and then use Find > Find Handle or DLL... and search on "BatchInfo.csv".
I am trying to set up a Qgis server on debian that uses a Qgis project file stored in a Postgres db.
To get started I followed the official Qgis Training Module Lesson 12.1.
When using a project file stored locally on the server, it works fine.
Now I tried to change the "default qgis project" in the qgis.demo.conf file and indicate my project file stored in the postgres database according to this template : postgresql://localhost:5432?sslmode=disable&dbname=mydb&schema=myschema&project=myproject which I found in the QGIS User Guide.
My edited line in the qgis.demo.conf looks like this:
SetEnv QGIS_PROJECT_FILE postgresql://localhost:5432?sslmode=disable&dbname=Test&schema=public&project=world
When doing a GetCapabilities request I now get:
"WMS configuration error" There was an error reading the project file or the SLD configuration.
I looked in the qgis.server.log to understand what is going wrong.
"Error, configuration file 'postgresql://localhost:5432?(...)' does not exist"
I am able to access the stored project file with qgis and with pgadmin 4 I can see that it is stored in the database.
Do I indicate the project file wrong?
you should complete the connectionstring with user and password
SetEnv QGIS_PROJECT_FILE postgresql://user:password#localhost:5432?sslmode=disable&dbname=Test&schema=public&project=world
I am facing issue while creating oracle_fdw.
I have copied oracle_fdw.dll to postgres lib folder *
both .sql file and control file to shrared/extension
now when I connect to psql with superadmin user & make an query
create extension oracle_fdw;
I am getting response
ERROR: could not load library "D:/postgresdb/lib/oracle_fdw.dll": The specified procedure could not be found.
From the error it seems that the oracle_fdw library is not available in the lib folder of postGreSQL installation directory.
You may download the Oracle fdw extension/or library file from https://github.com/laurenz/oracle_fdw/releases/ - please download the one suitable to your system environment(eg : 32bit windows/64bit).
Extract the downloaded .zip file.
copy the oracle_fdw.dll from \oracle_fdw-1.4.0-pg95-win64\lib folder to \Program Files\PostgreSQL\9.5\lib dir
&
2.copy all the files from oracle_fdw-1.4.0-pg95-win64\share\extension to \Program Files\PostgreSQL\9.5\share\extension
Now restart postGreSQL server and try.
Note : Always download and use compatible version of library; e.g.: PostgreSQL 9.5 version you should download same version of oracle_fdw zip.
Just had the same problem so this is what i did to resolve it. Not sure if all steps are needed since i was trying untill it worked.
Downloaded:
Instant Client Package
Instant Client Package - SQL*Plus
Instant Client Package - ODBC
From oracle (http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html)
Unzipped everything to one folder (c:\oracle)
Ran odbc_install in that folder
Added folder to PATH variable (System properties - Environment variables)
Restarted postgresql server
After that it worked. Also notice that you need the same version as your server (x86, x64).
Hope this helps.
I've added a custom application to my installer project and use it as recovery tool if something went wrong during update or if the new application data contains any bugs.
So far so good, restoring files and database works, but I can't figure out how to restore the version number. How can I implement this?
You would have to restore the file .install4j/i4jparams.conf in the installation directory. It contains the version number, also the file .install4j/response.varfile if you query installer variables in your code.
i am new to zend framework. i am trying to create a zend framework project in netbeans 6.9. but the ide shows some error, i couldn't understand. the following are the screenshots that could illustrate my problem.
the following are the error message shown in the ide log:
***************************** ZF ERROR ********************************
In order to run the zf command, you need to ensure that Zend Framework
is inside your include_path. There are a variety of ways that you can
ensure that this zf command line tool knows where the Zend Framework
library is on your system, but not all of them can be described here.
The easiest way to get the zf command running is to give it the include
path via an environment variable ZEND_TOOL_INCLUDE_PATH or
ZEND_TOOL_INCLUDE_PATH_PREPEND with the proper include path to use,
then run the command "zf --setup". This command is designed to create
a storage location for your user, as well as create the zf.ini file
that the zf command will consult in order to run properly on your
system.
Example you would run:
$ ZEND_TOOL_INCLUDE_PATH=/path/to/library zf --setup
Your are encourged to read more in the link that follows.
Zend_Tool & CLI Setup Information
(available via the command line "zf --info")
* Home directory found in environment variable HOMEPATH with value \Documents and Settings\oandz
* Storage directory assumed in home directory at location \Documents and Settings\oandz/.zf/
* Storage directory does not exist at \Documents and Settings\oandz/.zf/
* Config file assumed in home directory at location \Documents and Settings\oandz/.zf.ini
* Config file does not exist at \Documents and Settings\oandz/.zf.ini
To change the setup of this tool, run: "zf --setup"
can any one give the procedure to set-up zend framework and to configure it with netbeans 6.9 starting from scratch.
thanks in advance.
It looks like the cli Zend_Tool isn't being called. I'm not a windows man so the best I can provide is a link Using the CLI Tool there's a section on setting up in Windows.
The images are quite small so I'm guessing a bit but it looks like you pointed netbeans at the zf.bat file, are the permissions correct?
i resolved the problem. the problem is with zend framework 1.10.x itself. i just downloaded the latest version of the zend frame work and it just worked fine.
