OutOfMemoryError - through weblogic server

How to resolve OutOfMemoryError in weblogic server

Increase Heap size - -Xmx10G, -Xms10G implemented SFTP instead of FTP

byte[] fileArr = null; ByteArrayOutputStream out;

    StringBuilder strBuild = new StringBuilder();

    strBuild.append(path);

    strBuild.append(fileName);
InputStream inputStr = null;

    BufferedInputStream bis = null;

    ByteBuffer buffer = null;

    ReadableByteChannel inputChannel = null;
            WritableByteChannel outputChannel = null;


    try {

        inputStr = this.sftpClient.getInputStream(strBuild.toString());

                if(READ_BUFFER_SIZE <= 0){          

                    buffer = ByteBuffer.allocateDirect(DEFAULT_BUFFER_SIZE);
                }

                else{
                    buffer = ByteBuffer.allocateDirect(READ_BUFFER_SIZE);

                }

                bis = new BufferedInputStream(inputStr);

                out = new ByteArrayOutputStream();

                inputChannel = Channels.newChannel(bis);

                outputChannel = Channels.newChannel(out);

                while (inputChannel.read(buffer) > 0) {
                    buffer.flip();

                    outputChannel.write(buffer);

                    buffer.compact();
                }

Need response in ByteArray of input file

In your coude I don't see where you close your Streams. Probably server keeps your open buffers.

Insert a try-with-resource (https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html) or close your streams in your code
