Constants

Declared in: EDBMMHttp

Public constants exported by the library. All timeout values are in milliseconds and apply to the HTTP layer shared by TMMConnection, TMMScript, and TMMUpdater.

HTTP Timeout Constants

const
  HTTP_TIMEOUT_PING    = 10000;    // 10 s  -- ping only
  HTTP_TIMEOUT_DEFAULT = 30000;    // 30 s  -- one-shot actions
  HTTP_TIMEOUT_UPLOAD  = 60000;    // 60 s  -- per upload chunk
  HTTP_TIMEOUT_QUERY   = 120000;   // 2 min -- server-side DDL/DML
  HTTP_TIMEOUT_RUN     = 300000;   // 5 min -- script execution
  HTTP_TIMEOUT_BLOB    = 1800000;  // 30 min -- BLOB/CLOB and result pages

Constant	Value	Used for
HTTP_TIMEOUT_PING	10 s	TMMConnection.Ping
HTTP_TIMEOUT_DEFAULT	30 s	TestConnection, GetColumnInfo, GetTableColumns
HTTP_TIMEOUT_UPLOAD	60 s	Each upload chunk during TMMScript.Execute
HTTP_TIMEOUT_QUERY	2 min	Server-side DDL/DML execution
HTTP_TIMEOUT_RUN	5 min	Script execution phase of TMMScript.Execute
HTTP_TIMEOUT_BLOB	30 min	BLOB/CLOB transfer, result page fetches, TMMUpdater.Execute chunks

All timeouts are fixed at compile time and cannot be changed at run time, with one exception: TMMConnection.TimeoutMs, when non-zero, overrides HTTP_TIMEOUT_PING and HTTP_TIMEOUT_DEFAULT for Ping and TestConnection on that connection.
