For those that have Oracle Reports running, be aware. Updating the latest RedHat 6 or 7 updates will break the Oracle Reports execution.
For example upgrading to the latest RedHat 6.9 caused all the reports to be failing with signal 11 or signal 6.
This is a known issue (referring to Oracle technical note 2280616.1).
For fixing edit the reports.sh file
Reports 11.1.2.x:
File: INSTANCE_HOME/config/reports/bin/reports.sh
Add in the last line:
REPORTS_JVM_OPTIONS="-Xss2M"; export REPORTS_JVM_OPTIONS
Reports 12.2.1.x:
File: DOMAIN_HOME/reports/bin/reports.sh
Add in the last line:REPORTS_JVM_OPTIONS="-Xss2M"; export REPORTS_JVM_OPTIONS
After modifying, restart the Reports server.
