A SocketTimeoutException can occur when performing a variety of different tasks in WebSphere, such as when attempting to synchronize a node to a dmgr, running a wsadmin script, or configuring the IHS web server plugin, just to name a few.
[SOAPException: faultCode=SOAP-ENV:Client; msg=Read timed out;
targetException=java.net.SocketTimeoutException: Read timed out]
A socket timeout exception is almost always associated with a SOAP connection. The socket timeout period is set in the ${was_install_root}/profiles/your_profile/properties/soap.client.props file. By default, the timeout is set to 180 seconds (3 minutes).
com.ibm.SOAP.requestTimeout=180
If the task you are performing is indeed taking longer than 3 minutes, you can increase the SOAP timeout, and then restart the cell for the change to take effect. If you continue to get a socket timeout exception, then there are other things that may be causing the socket timeout exception. Following are some things to consider.
