I created a database in Neo4j via eclipse. How to view this database on neoclipse? I've seen some tutorials but I don't understand. Can someone help me?
You would point neoclipse to the data directory on disk or to the server http URL that hosts your data.
Probably easier to copy your database directory contents to a neo4j-server's /path/to/neo/data/graph.db

I am using Azure PostgreSQL, in my web project, I save files(such as images,.csv) in table as bytea data type.
Now I can get files from Azure PostgreSQL successfully, but the performance is not so good. it will take more than 20s to retrieve files if I request for multiple files, even sometimes I got timeout error from my web server. So is there anyone could give me some advice to solve this? Any suggestion is appreciated.
As #eshirvana said, saving files in databases is not a good idea. As we know,the performance that querying blobs or files in SQL is awful and it also greatly cost DB server memory. Saving URLs in DB only is recommended.
If you are using Azure Cloud, you can save your files in Azure blob storage. And you can save your file storage blob URL in your DB table.
Your client could get the file URL from the webserver by SQL query and access files in Azure storage by the file URL. This way could ease the IO and memory pressure of your web server and greatly improve the query performance.
What's more, creating your SQL service in the region that you are in or near could also reduce network latency. You can see all the Azure datacenter regions here.
as some of you might aware about the shutting down of parse service in about a year, i am following the migration process as per their tutorials. However, i am not able to migrate these data from parse to local database(i.e. mongodb).
I've started the mongodb instanse locally on 27017, and also created an admin user as part of migration based on these tutorials. Reference-1 & Reference-2.
But when i try to migrate the data from parse developer console, i get No Reachable Servers or Network Error & i don't understand why. I have doubt in the Connection string that i use for this but i am not sure, please find the following image.
I am new to mongodb so don't have much idea about this, your little help would be greatly appreciated.
Since the migration tool runs at parse.com, the tool needs to be able to access your MongoDB instance over the Internet.
Since you're using a local IP (192.168.1.101), parse.com cannot connect to your IP and the transfer will time out.
Either you need to make your MongoDB reachable from the Internet, or you can - as they do in their guide - use an existing MongoDB service.
I am facing a problem with mongo DB connection.
I have succefully imported tMongo components it to my Talend Open Studio 5.1.1 and by copying the mongo 1.3.jar file to lib/java folder, my Mongo DB jobs are running successfully, but the problem is even if I provide some fake server path(IP) and fake port for mongoDB, my job is running without an error and it is giving me 1 row with no data. and same goes with right IP and port.
How do I resolve it.
I think the connection is not working. As you must be knowing, mongoDB checks that the connection is actually working or not when you perform a query on it.
(Yeah, it doesn't check for a successful connection when you just connect to it ).
I would suggest to instead add the mongoDB components present in Talend for Big Data by following the steps below:
Components provided for MongoDB are :
tMongoDBInput, tMongoDBOutput, tMongoDBConnection etc.
Or you can Download the components from http://www.talendforge.org/exchange/ and search for Mongo instead of using Talend Big Data. But I would suggest use Talend for big Data for it.
The components will be zipped format , Unzip the same. In Talend Big data you will find the components in Component folder.
Copy these Unzipped Components to the installation Path of TOS.
C:TalendTOS_DI-Win32-r84309V5.1.1pluginsorg.talend.designer.components.localprovider_5.1.1.r84309components
Copy the mongo-1.3.jar file in the component folder into the C:TalendTOS_DI-Win32-r84309-V5.1.1libjava
In many systems you might not be able to see this file then go with ADMINISTRATOR priviliges.
optional for few systems——>>> Inside index.xml add
save index.xml
Restart TOS
Then you will be able to use them as normal components.
Cheers!
The reason for the Job running without any error could be due to the connection / meta-data you have used for the Mongo Connector. It doesn't is not possible for the job to run without any error even after giving fakepath.
I guess you might configured (re-modified) the repository connection but using a built-in meta data for component.
I know this is a very basic question.I am new to web programming.Im working with a CMS.My client has asked me to 'FTP' the site that i am manipulating on my local machine, so that he can view the changes too.He also gave a link on cliking which, the site pops up in its original form.I understand that its hosted on a server and i am suposed to make it look like the one i have modified on local.How do i do this?using an FTP client.What about the database?
And also what if something goes wrong during the process?Is it undoable?
I would have done much more research before asking this question, but i have got so little time to figure this out.Thnks
Encourage your client to use scp or sftp instead. It'll encrypt the login and traffic.
Get an FTP program like WSFTP.
What about the database? You need a copy of the database on the server (which is presumably where the link goes).
Get the login/pass from the client.
It's un-doable if you have a copy or backup of the original.
FTP copies files from one machine to another. Sounds like you need to install the CMS on the server.
Need more information: what CMS, is it already on the server, what database?
I've wrote the code that creates full backups of my ESENT database, using JetBeginExternalBackup API.
Following the MSDN guidelines, I backed up every file returned by JetGetAttachInfo and JetGetLogInfo.
I've made the backup, erased old database, and copied the backup data to the database folder.
The DB engine was unable to start, the JetInit error code is "JET_errMissingLogFile".
I've checked the backup, it only contains the database file, and "<inst>XXXXX.log" log files. It lacks the current log file (I'm using circular logging, BTW).
Is there any way to restore such backup?
I don't want to use JetExternalRestore API because it's too complex: I don't need to restore to another location, I don't understand why there're 3 input folders not 2, and I don't know the values to supply in genLow and genHigh arguments.
I do need external backups: the ESENT database is used by ASP.NET on a remote server, and I'm backing it up over the Internet.
Or, maybe there's a way to retrieve the name of the current log file, and I should just add it to the backup?
Thanks in advance!
P.S. I've got no permissions to span processes on my web server, so using eseutil.exe is not an option.
Unpack all backed up files to a single folder.
Take the name of your main database file. Replace extension to .pat. Create zero-length file with that name, e.g. database.pat.
After this simple step, call JetRestoreInstance API, it will restore the backup from that folder.
