如果要让超时功能失效, 在DSN设置查询超时为disabled:
Windows Control Panel > Administrative Tools > Data Sources (ODBC) > System DSN configuration
如果勾选了Disable query timeout , 超时就会失效.
如果想在应用侧修改，你可以在ODBC API 层设置：在连接数据源之前，调用ODBC SQLSetStmtAttr功能设置SQL_ATTR_QUERY_TIMEOUT 属性

InterSystems 产品里数据 (表、对象、实例数据) 是存在global 变量里的。
每个global 的数据大小可以从管理门户中中点击属性查看Management Portal > System > Configuration > Local Database > Globals page, 然后在global 属性页点击计算大小Calculate Size 按钮。
你可以在终端上调用^%GSIZE 来在命名空间里显示数据大小，方法如下.
USER>do ^%GSIZE
Directory name: c:\intersystems\ensemble\mgr\user\ =>
All Globals? No => Yes
^DeepSee.ActiveTasks contains no data
Include it anyway? No => Y
Include any other similar globals without asking again? Yes =>

// set transfer mode to BINARY
do ftp.Binary()
// Move to the directory to upload
do ftp.SetDirectory("/temp/upload")
// Prepare a stream of files to upload
set file=##class(%File).%New(tmpfile)
do file.Open("UK\BIN\")
// upload file
// 1st argument: File name to create at upload destination
// 2nd argument: File stream to upload
do ftp.Store("test.jpg",file)
// Logout from ftp server
do ftp.Logout()
// close the file
do file.Close()
// (Optional) Delete the uploaded file

2. 从FTP服务器下载
set ftp=##class(%Net.FtpSession).%New() // Connect to ftp server
do ftp.Connect("","<username>","<password>") // Set the transfer mode to BINARY
do ftp.Binary() // Prepare a file stream to download and store
set stream=##class(%FileBinaryStream).%New()
do stream.LinkToFile("c:\temp\testdownload.jpg")
// Go to the download directory
do ftp.SetDirectory("/temp/download") // Download the file and close the stream
