Using ACN Connection Pool

Question

I use JSCH to download sftp files ever. In this current state, each thread opens and closes the connection when necessary.

If you can use the connection pool with AOX to avoid the overhead caused by a large number of open and close connections?

Here is an example of a function called from within a thread

public static void file_upload(String filename) throws IOException { JSch jsch = new JSch(); Session session = null; try { session = jsch.getSession("user", "server_name", 22); session.setConfig("StrictHostKeyChecking", "no"); session.setPassword("super_secre_password"); session.connect(); Channel channel = session.openChannel("sftp"); channel.connect(); ChannelSftp sftpChannel = (ChannelSftp) channel; FileInputStream inputSrr = new FileInputStream(filename); try { sftpChannel.put(inputSrr, "/var/temp/"+filename); } catch (SftpException e) { e.printStackTrace(); } finally { if (inputSrr != null) { inputSrr.close(); } } sftpChannel.exit(); session.disconnect(); } catch (JSchException e) { e.printStackTrace(); } catch (SftpException e) { e.printStackTrace(); } } 

Answer 1

For this, I would prefer a shared pool .;)

Answer 2

Here's the implementation of the Ssh connection pool http://www.javacodegeeks.com/2013/02/pool-of-ssh-connections-using-apache-keyedobjectpool.html

you can use grep4j to use this pool https://code.google.com/p/grep4j/source/browse/trunk/src/main/java/org/grep4j/core/command/linux/SessionFactory.java?r= 354

Also make sure that you can access the server from the runtime device. For example, if the target server is unavailable. This will cause a connection timeout.
