Getting "Unable to invoke Oracle HTTP Server Details" message for Request throughput and server response time.
Solution:
Check if the OHS(Oracle HTTP Server) server is running. If not, start the OHS using the following steps :
1.To start all OHS components in an Oracle instance, using opmnctl, use :
- $ORACLE_INSTANCE/bin/opmnctl startproc process-type=OHS
2.To start a specific OHS component, using opmnctl, use :
- $ORACLE_INSTANCE/bin/opmnctl startproc ias-component=<component_name>
3.To get detailed information about the start process, include the verbose option with the command as follows :
- $ORACLE_INSTANCE/bin/opmnctl verbose startproc ias-component=<ohs_name>
After starting the OHS, check whether data collection is happening, from the host where Applications Manager is installed, by launching the following URL in the browser :
http://<hostname_or_IP_of_the_OHS>:<port>/dmsoc4j/AggreSpy?format=metrictable&cache=false&interval=6400000&table=ohs_server&orderby=Name
