Description
Description:
This articles describes the impact of "/dev/random" file in resolving JDBC error: (SQLState = 08006) - java.sql.SQLRecoverableException: IO Error: Connection reset.
Symptoms:
When starting numerous applications simultaneously the following error may be encountered :
"JDBC error reported: (SQLState = 08006) - java.sql.SQLRecoverableException: IO Error: Connection reset".

caused by: java.sql.SQLRecoverableException: IO Error: Connection reset
at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:421)
Cause:
This error is seen because the JDBC thin clients uses /dev/random for security purposes and the amount of activity determines how fast /dev/random can deliver random numbers. By default, JDBC uses /dev/random and could cause the JDBC connection creation to hang when /dev/random cannot generate random numbers fast enough.

Issue/Introduction
JDBC error "(SQLState = 08006) - java.sql.SQLRecoverableException: IO Error: Connection reset" and "/dev/random" file
Resolution
JDBC could be made to use /dev/urandom by specifying it as a system property (triple "/" is needed). Add the following property in the application tra file and restart the application:
java.extended.properties -Djava.security.egd=file:///dev/urandom
java.extended.properties -Djava.security.egd=file:///dev/urandom
