logintimeout - Set or get time allowed to establish database connection

Syntax

timeout = logintimeout('driver', time) timeout = logintimeout(time) timeout = logintimeout('driver') timeout = logintimeout

Description

timeout = logintimeout('driver', time) sets the amount of time, in seconds, for a MATLAB software session to connect to a database via a given JDBC driver. Use logintimeout before running the database function. If the MATLAB software session cannot connect to the database within the specified time, it stops trying.
timeout = logintimeout(time) sets the amount of time, in seconds, allowed for a MATLAB software session to try to connect to a database via an ODBC connection. Use logintimeout before running the database function. If the MATLAB software session cannot connect within the allowed time, it stops trying.
timeout = logintimeout('driver') returns the time, in seconds, that was previously specified for the JDBC driver. A returned value of 0 means that the timeout value was not previously set. The MATLAB software session stops trying to connect to the database if it is not immediately successful.
timeout = logintimeout returns the time, in seconds, that you previously specified for an ODBC connection. A returned value of 0 means that the timeout value was not previously set ; the MATLAB software session stops trying to make a connection if it is not immediately successful.

Note If you do not specify a value for logintimeout and the MATLAB software session cannot establish a database connection, your MATLAB software session may freeze.

Note Apple^® Mac OS^® platforms do not support logintimeout.

Examples

Example 1 — Get Timeout Value for ODBC Connection

View the current connection timeout value.

 logintimeout
 ans =
     0

This indicates that you have not specified a timeout value.

Example 2 — Set Timeout Value for ODBC Connection

Set the timeout value to 5 seconds.

logintimeout(5)
ans =
     5

Example 3 — Get and Set Timeout Value for JDBC Connection

Check the timeout value for a database connection that is established using an Oracle JDBC driver.
```
logintimeout('oracle.jdbc.driver.OracleDriver')
ans =
     0
```
This indicates that the timeout value is currently 0.

Set the timeout to 5 seconds.

timeout = ...
logintimeout('oracle.jdbc.driver.OracleDriver', 5)
timeout =
     5

Verify the timeout value.

logintimeout('oracle.jdbc.driver.OracleDriver')
ans =
     5
