OrientDB Studio looked to be a promising tool to explore the product for use as an object store replacement for db4o, but I unfortunately I have not been able to get to first base with it.
I am running OSX 10.6.8. The behavior described below was observed with both the 1.7.10 Mac and the 1.7.9 "all platforms" binaries:
1) I am not able to create a database with Studio. I edited the root password and restarted the server but any attempt to create a new database using Studio yields the same result: 401 Unauthorized.
And there is not much information in the logs:
2014-11-20 12:12:32:420 CONF Remote client connected from: OClientConnection [id=1, source=?, since=1416503552420] [OClientConnectionManager]
2014-11-20 12:12:32:431 FINE [ONetworkProtocolHttpAbstract.execute] Requested: POST /database/invoices/local/document [ONetworkProtocolHttpDb]
2014-11-20 12:12:32:438 FINE Disconnecting connection with id=1 [OClientConnectionManager]
2014-11-20 12:12:32:438 FINE Disconnected connection with id=1, no other active channels found [OClientConnectionManager]
2014-11-20 12:12:32:438 FINE Connection shutdowned [ONetworkProtocolHttpDb]
I had to resort to creating the new database using the console. Having to resort to using the console steepens the learning curve and is a barrier to adoption.
2) I would like to use Studio to create indexes and explore index behavior, but I do not seem to be able to open any database, even the demo GratefulDeadConcerts, as writer or admin.
Studio displays the mode (reader) at the top right of the page, and I have to believe I have no write privileges because I am not able to create any indexes on my new object database.
Any help would be Gratefully (pun intended) appreciated.
The problem is apparently not with either OrientDB or Studio.
1) I continued to test with OSX 1.7.10. Logging in as admin/admin, I noticed that Safari would open the databases as (admin) but Firefox would open the databases as (reader). After upgrading to Firefox 33.1.1 the mode now shows as (admin) and I am now able to create databases using Studio.
I just deleted localhost cookies in Safari 5.1.10 and was able to create a database using that browser as well. It's possible that step may required after changing the root password and restarting the server.
2) My problem with index creation was due to lack of understanding of how indexes work. Indexes can only be created on objects with schema-defined properties.
After opening the database and requesting schema generation using the API, Studio displayed class properties and I was able to create indexes on those properties in Studio.
db2 = new OObjectDatabaseTx("remote:localhost/invoices").open("admin", "admin");
// Tell OrientDB to automatically generate schema during class registration, this saves us some code.
db2.setAutomaticSchemaGeneration(true);
// Now register our classes...
db.getEntityManager().registerEntityClasses("your.entity.package.goes.here");
// Save the schema of our new database...
db2.getMetadata().getSchema().save();

I am using Google's Datastore (which is Firestore's support for the GCP) and the emulator to handle storage locally. Everything works fine as far as storing data. But there does not appear to be any way of actually viewing the data in the browser. I have a feeling that this is not yet implemented because the emulator is still in beta. Has anyone been able to view data in their browser? It should be stressed that this is the emulator provided by the Google Cloud Platform SDK and not the one that Firebase uses for its products. The emulator is started with:
gcloud beta emulators datastore start
As of January 2022
Debugging
Setting up Firebase Datastore Emulator (FDE)
The Firebase Datastore Emulator (FDE) emulates the Google Datastore in App Engine. This is meant to run on Java 8 platforms. When correctly setup, any Datastore operations are done locally and stored to a file called local_db.bin.
The documentation for using the Firebase Datastore Emulator can be found at:
https://cloud.google.com/datastore/docs/tools/datastore-emulator
It should be noted that this documentaton contains errors and is missing some important settings. To use Firebase Datastore Emulator, install the emulator by running the following command from a terminal:
gcloud components install cloud-datastore-emulator
Start the emulator in a terminal:
gcloud beta emulators datastore start --data-dir=fbdatastore --host-port=localhost:8100
The official documentation does not indicate to use the --host-port flag. If you leave this flag out, a random port will be selected. But experience has shown that letting the port be randomly selected can result in exceptions generated by the client library used to access the local datastore - even when the port is correctly set in the environment variables.
The --data-dir flag indicates the directory where the local database file is stored. Here, it is specified as fbdatastore but you can use any folder located anywhere. You should make sure that the folder already exists before you start the emulator. In the example shown here, no path is included. This means that when you start the emulator, the directory specified by --data-dir should be in the same folder where you are launching the emulator.
The emulator will only create the local_db.bin file when you initially write data to it. If you don't write any data, it will not be created. Even it isn't created, the client APIs will still work correctly when reading from it, typically returning null values for any entities that you attempt to access. No exception will be thrown if the database file does not exist.
If the --data-dir is set to fbdatastore as used here, the local_db.bin file will be created under:
fbdatastore/WEB-INF/appengine-generated/local_db.bin
After the emulator has started, you can verify that it is running but opening a browser window and navigating to the url:
http://localhost:8100
This will only display the text "ok".
Before you can start debugging the app, several environment variables need to be set. You need to open a new terminal window and execute the following commands to set several variables:
export DATASTORE_DATASET=[project-id]
export DATASTORE_EMULATOR_HOST=localhost:8100
export DATASTORE_EMULATOR_HOST_PATH=localhost:8100/datastore
export DATASTORE_HOST=http://localhost:8100
export DATASTORE_PROJECT_ID=[project-id]
export DATASTORE_USE_PROJECT_ID_AS_APP_ID=true
The client libraries for the Datastore expect the app id to be used. But it was found that using only the app id didn't work. The environment variable DATASTORE_USE_PROJECT_ID_AS_APP_ID needs to be set as well. This is not specified in the documentation.
It should be noted that the official docs show the following:
export DATASTORE_DATASET=my-project-id
export DATASTORE_EMULATOR_HOST=::1:8432
export DATASTORE_EMULATOR_HOST_PATH=::1:8432/datastore
export DATASTORE_HOST=http://::1:8432
export DATASTORE_PROJECT_ID=my-project-id
For MacOS, this is wrong. The variables with values set to ::1 is wrong. Using this will cause exceptions and probably prevent the emulator from even loading. The ::1 needs to be replaced with localhost, as shown above.
You can just copy the 6 lines shown above and paste them into a terminal and hit Enter. But it is easier to just place these into a bash file and execute it. These need to be set before the local development server is started. The following bash file will set the environment variables and then start the development server:
export DATASTORE_DATASET=[project-id]
export DATASTORE_EMULATOR_HOST=localhost:8100
export DATASTORE_EMULATOR_HOST_PATH=localhost:8100/datastore
export DATASTORE_HOST=http://localhost:8100
export DATASTORE_PROJECT_ID=[project-id]
export DATASTORE_USE_PROJECT_ID_AS_APP_ID=true
java_dev_appserver.sh --address=0.0.0.0 --port=8080 --disable_update_check --jvm_flag=-Xdebug --jvm_flag=-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000 build/exploded-website
Replace [project-id] with the project id shown in your Googel Cloud Platform console (don't include the square brackets).
The address parameter for java_dev_appserver.sh is set here to 8000. You will need to set this in your IDE. Also, the port for java_dev_appserver.sh is set to 8080. You can set this to whatever works on your system and doesn't conflict with any existing ports used elsewhere. The last parameter for java_dev_appserver.sh is the location of your war files, which is the compiled app. Here, it is located at build/web-site. Replace this with the location of your own build files.
To view the datastore locally in your browser, navigate to:
http://localhost:8080/_ah/admin/datastore
Details on the command parameters used to start the emulator can be found at:
https://cloud.google.com/sdk/gcloud/reference/beta/emulators/datastore/start
As far as I can understand what you want to do is to add data in the Datastore emulator running on your console and be able to see this data in the UI right?
Vieweing the data in the UI actually incurs in expenses for you because Datastore have to query the data to be able to display it on the UI.
I can still recommend you to create a Feature Request if you want to be able to see the entries form the Datastore emulator for free in the UI
Situation:
Have created today a new Compose for MongoDB Service instance in Bluemix
Need:
I have to access this MongoDB DIRECTLY with tools (eg. Mongo Managemant Studio Pro, mongo.exe, etc.) for bulkloading, testing, ad-hoc data fix, etc.
Problem:
I have not found any docs, samples nor a CLEAR statement that
a) gives me some confirmation that THIS is possible
b) gives me COMPLETE information (not just some technical fragments that might have worked year ago) how to do it.
Maybe I am looking to the wrong places or do not know the right people. However I am stuck on this, and before quitting Bluemix MongoDB maybe somebody has a copy/past solution or handson step by step manual.
Any help welcome. Thanks!
Connecting to MongoDB service in Bluemix from an application is possible. For this answer I have used the application "Robo3T" and here are the steps:
Access your MongoDB Service on you Bluemix account. Usually under
"Cloud Foundry Services"
Open section "Manage", from "Connection Settings" copy from "HTTPS" the connection address and port. In this example "sl-eu-lon-2-portal.5.dblayer.com" and "20651"
In Robo3T create a new connection with the connection address from previous step
In tab Authentication configure database name, username and password
. The credentials are found as in step 1
From "Connection Settings" copy the SSL Certificate into a text file and save locally.
In Robo3T Add the certificate to the connection in the "SSL" tab
Test the connection and save the settings
Answer
YES, Bluemix hosted Compose for MongoDB instances can be connected from the mongo Shell and some updated DB Managment tools.
However, you have to make sure, that in case you are running the newest DB versions, that your tools (shell and DB management GUIs) comply with the newest DB features such as encryption etc.
Origin of the Problem
My problem was due to older and therefore incompatible versions of the mongo shell and DB-managment tools running against the newest MongoDB versions with their specialities on encription and multiple servers to be handled in the URI.
At least two DB managment tools are not compatible with the newest DB version and will take their time to get fixed. The problem is, that both will not tell you about this. They just do not not connect. No logs on either side. Period.
So my advise here: look for tool providers who express dedicated compliance with the specific version of your DB.
Advise to the Bluemix Team
It might not take much time to provide some sample connection strings for the most common tools like the mongo shell, MongoBooster, etc. to take the hassle and guesswork out of interpreting the Environment variables and figuring out what is needed for specific connection strings and what is not.
For instance MongoDB Atlas hosting provides for every cluster readymade connection strings for many tools you can just copy/past and done!
Connecting to Atlas took me 5 Minutes. For Bluemix I have lost hours! Not because it is complex, but because the documentation and the generated Info is somehow incomplete and messy - at least for the ones who do not connection strings for their living!
So I've started a SQL Server database project inside VS 2012. I have done this for other databases already but not related to Service Broker.
For testing I had already created db, queues, etc through a T-SQL script including Message Types which was in an XML format. i.e.
[//blah.com/Items/RequestItem]
When I try to do something like this in the DB Project it's not allowing me too due to special chars.
Anyone done this? Gotten around it?
Is there a way to simply put my already created T-SQL file in the database project and have it use it?
See my comment above. I was able to import the script by Right clicking on the database Project.
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.
ASP.NET Membership is just great as there are a ton of functionality right there to be used, and we don't need to change nothing at all.
We can even create our own Provider based on Membership database, and that give us infinite possibilities, like as I don't like the Question/Answer I just use an email that is sent with a reset link.
But this is all done with SQLEXPRESS .mdf file and I wanted to use my own Database for this so I can use SQL Server Enterprise as we have in the Office and not the Express Edition.
How can I easily use the ASP.NET Membership tables in my own Database?
I rememebered some years ago that we needed to use aspnet_reg (something) to create the correct tables, but I can't find that info anymore.
I also tried to use other Membership Providers, namely Altairis.Web.Security from CodePlex and saw the Chris Pels Video on creating a new Membership Provider
On Altairis solution, the Model is not complete and lack several points such as Several Applications as it's made to be used with only one, and Chris Pels contains to much Store Procedures that I need to create by hand.
I'm for given Chris code a go but I just wanted to know if there would be available something easier.
All this is to be integrated in ASP.NET MVC 2 Web Application.
Thanks
You have 3 options:
Do it by running aspnet_regsql.exe: Just open "Start Menu>All Programs>Microsoft Visual Studio 2010>Visual Studio Tools>Visual Studio Command Prompt(2010)" and then type aspnet_regsql. A wizard appears and let you select your desired database.
Do it via API: Use System.Web.Management.SqlServices class and its Install and Uninstall methods. This will programmatically install/uninstall database artifacts.
Do it manually: Go to C:\Windows\Microsoft.NET\Framework\v4.0.30319 or something like. You will find 9 .sql files that begins with Install and 9 .sql files that begins with uninstall. You can run them manually in your database to create needed tables/store procedures/etc. But consider changing database name in sql scripts. Default db name is aspnetdb.
It's aspnet_regsql
Under the following path:
C:\windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regsql
You need to open up the Visual Studio Command Prompt, navigate to C:\WINDOWS\Microsoft.NET\Framework\\aspnet_regsql.exe . Some example are located in the MSDN documentation.
Example: aspnet_regsql.exe -E -S localhost -A mr - installs the database elements for membership and role management on the local computer running SQL Server using Windows authentication.
