got it ,thank you.

@luigidellaquila

wait please... db.command(String query, Object... args) throw the exception too.

OrientDB Version: 3.2.0

Java Version: 8

maven dependency: orientdb-client 3.2.0

i want to drop class named "zzz"

can work:

        ODatabaseSession session = pool.acquire();
        OResultSet rs = session.query("drop class zzz");
        rs.close();

not work:

        ODatabaseSession session = pool.acquire();
        OResultSet rs = session.query("drop class ?" ,"zzz");
        rs.close();

is it unsupported ?

OrientDB Version: <3.2.0>

Java Version: <1.8>

OS: <mac os 11.3.1>

Expected behavior

Am pushing batch of vertex through REST API from java via Thread.It results in Socket java.net.SocketTimeoutException: Read timed out .Am i missing any configuration here ?I've tried configuring NETWORK_SOCKET_TIMEOUT,still same exists.Kindly help me on this.

It all depends on how big is each vertex. How many properties? Do you have binary or long strings? If you can compute that amount in terms of total Kb sent it would be helpful.

Generally speaking, if you're sending big packets concurrently, OrientDB's web socket could having hard time to process the requests.

Try reducing the parallel threads from 10 to 3 and see how it goes. Also from 1000 vertices, try with 300.

Try to play around those numbers to see a good configuration based on your data and hw/sw available.

I am inserting 1000 vertices as JSON through rest API from java.

1,000 operations or 1,000 bytes? How big is the packet in Kb/Mb?

The size of the packet is 1000 and parallely running 10 threads.

3.1.7 also works. I cant go beyond this.

OrientDB Version: 3.2.0

Java Version: openjdk version "11.0.11"

OS: Ubuntu 21.04

Expected behavior

To run a batch script with lot of inserts or updates without consuming all available connections.

Actual behavior

When running a batch script through the console, it seems like each insert or update is consuming one "connection", so the limit is reached and no new connections can be made (although the script is still executing fine). The server logs Reached maximum number of concurrent connections (max=1000, current=213837), reject incoming connection from /127.0.0.1:52756 [OServerNetworkListener].

Steps to reproduce

I can reproduce it with a fresh install of 3.2.0. Unzip zip and start server.

Create a script with thousand lines like this: create vertex V set num = 1; ...

In console:

orientdb> connect remote:localhost/demodb admin admin;

Connecting to database [remote:localhost/demodb] with user 'admin'...OK

orientdb {db=demodb}> load script script.sql;

Try to connect to server (i.e. opening Studio) while the script is executing, the connection is rejected and logs:

Reached maximum number of concurrent connections (max=1000, current=3779), reject incoming connection from /127.0.0.1:57932 [OServerNetworkListener] ("current" is an increasing number).

OrientDB Version: 3.2.0 (docker)

Errors are produced when executing custom JS functions that call documented "built-in" functions such as orient.getDatabase().

Setting script.polyglot.useGraal = false does not make a difference.

Errors

The following error is seen in Studio:

Error on parsing script at position #0: Error on execution of the script Script: test ------^

org.graalvm.polyglot.PolyglotException: TypeError: invokeMember (getDatabase) on com.orientechnologies.orient.core.command.script.OScriptOrientWrapper@2db24b13 failed due to: Unknown identifier: getDatabase

Executing a similar function from a SQL batch script causes the same error:

Error on parsing script at position #0: Error on execution of the script

... as well as this stack trace:

Steps to reproduce

Create a JS function containing the following line, and execute it.

var db = orient.getDatabase();

@KirubakaranSP Yep, just pushed a fix. Now with SCRIPT_POLYGLOT_USE_GRAAL = false everything works. Note: Nashorn returns ClassNotFoundException instead of ScriptException in case the Java class cannot be accessed.

@koiralo I would be very happy if you can do that ;-)
