If you run the opmnctl status command following the successful execution of the opmnctl startall or opmnctl startproc command, the status output indicates Log Loader status as down.īy default, the Log Loader element in the opmn.xml file is not configured to start when you execute the opmnctl startall or opmnctl startproc command. This technique ultimately does not eliminate the problem, because there is the possibility that OPMN will not find a port that works in the number of port connection attempts that you have specified in the opmn.xml file. If you have identical port ranges in two Oracle homes and increase the number of times OPMN attempts to restart a process, OPMN will eventually select a port that works. It is also recommended that you increase the maximum number of retries for starting OC4J instances. The OPMN process in one Oracle home and the OPMN in a different Oracle home will not attempt to use the same port numbers when assigning OC4J ports, and will not attempt to bind to the same port. To coordinate port usage, assign unique port ranges to each Oracle home. However, when two OPMN processes on a host start at the same time, there is no coordination between them on port usage. An OC4J instance in one Oracle home is trying to use the same port as an OC4J instance in a different Oracle home.Port allocation for all OC4J instances within Oracle Application Server is controlled by OPMN there can be overlapping port ranges within a single opmn.xml file. This may occur when two Oracle homes on the same host use the same port ranges for RMI, JMS, and AJP ports. "failed to restart a managed process after the maximum retry limit" You may receive an error message such as: If you have multiple Oracle Application Server installations on one host and you start them at the same time (for example, to start a cluster), OPMN may become unresponsive. Increase the log level in the file to obtain additional information. For example, ORACLE_HOME /discoverer/logs.Įxamine the ORACLE_HOME /opmn/logs/ipm.log for any indication of problems. Review the component-specific log file for the Oracle Application Server component that is not starting. Look at the ORACLE_HOME /opmn/logs/ for the Oracle Application Server process that is not starting. This functionality is available with the startproc command which will start all the relevant processes configured in opmn.xml.Ĭheck the start element in the opmn.xml file and change the retry attribute to a higher increment of time. Set the timeout in the opmn.xml file at a level that will allow OPMN to wait for process to come up. Increase the start element timeout attribute for the component that is not starting. To verify successful execution of the opmnctl command, try the following: If an OC4J process does not start-up after an opmnctl command, OPMN will wait approximately an hour before timing out and aborting the request. The default start time out for OC4J is approximately five minutes. Because of this the time it takes to execute an opmnctl command may not be readily apparent. The time it takes to execute an opmnctl command is dependent on the type of Oracle Application Server process and available computer hardware.
