Oracle Database Socket Read Timed Out
closed the session due to some sort "inactivity" java.sql.SQException: Io exception: Socket read timed out : This is a case where the connection was made successfully but for some reason the socket/data was empty and eventually it timed-out because no data was available. Is it possible to replicate the above errors in a local Oracle DB env ? What are the steps ? I appreciate you taking the time to respond. Thanks. java sql oracle exception jdbc share|improve this question edited May 21 '13 at 20:46 Konstantin Yovkov 45.2k54296 asked May 21 '13 at 20:40 kart0624 45116 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote I have just started working with the java.sql.* package, but here is what I understand. A closed connection is an error that occurs and the DB session closes, but no error handling is done so that is the end of it. With java.SQException you can manage this error (use a throws clause) and print it out or do other error handling methods. Here is a link from Oracle about Exceptions and how t

Action: Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name.

may have devices such as a digitizing tablet, function button box, or dial box that are connected via normal asynchronous serial interfaces; good user interface style requires responding immediately to input on any device. Another example is a program that acts as a server to several other processes via pipes or sockets. You cannot normally use read for this purpose, because this blocks the program until input is available on one particular file descriptor; input on other channels won’t wake it up. You could set nonblocking mode and poll each file descriptor in turn, but this is very inefficient. A better solution is to use the select function. This blocks the program until input or output is ready on a specified set of file descriptors, or until a timer expires, whichever comes first. This facility is declared in the header file sys/types.h. In the case of a server socket (see Listening), we say that “input” is available when there are pending connections that could be accepted (see Accepting Connections). accept for server sockets blocks and interacts with select just as read does for normal input. The file descriptor sets for the select function are specified as fd_set objects. Here is the description of the data type and some macros for manipulating these objects. Data Type: fd_set The fd_set data type represents file descriptor sets for the select function. It is actually a bit array. Macro: int FD_SETSIZE The value of this macro is the maximum number of file descriptors that a fd_set object can hold information about. On systems with a fixed maximum number, FD_SETSIZE is at least that number. On some systems, including GNU, there is no absolute limit on the number of descriptors open, but this macro still has a constant value which controls the number of bits in an fd_set; if you get a file descriptor with a value as high as FD_SETSIZE, you cannot put that descriptor into an fd_set. Macro: void FD_ZERO (fd_set *set) Preliminary: | MT-Safe race:set | AS-Safe | AC-Safe | See POSIX Safety Concepts. This mac
