+++ This bug was initially created as a clone of Bug #1110277 +++

JON 3.1.2 and JON 3.2.0

org/​ rhq/​ core/​ domain/​ event/​ Event.java

126     @Column(name = "DETAIL", length = 4000, nullable = false)
127     private String detail;

so the detail string is trimming the text to 4000 UTF8 characters.


org/​ rhq/​ enterprise/​ server/​ event/​ EventManagerBean.java 

is responsible to insert the event into the database:

112     public void addEventData(Map<EventSource, Set<Event>> events) {
...
167             // Then insert the "values" (i.e. the Events).
168             ps = conn.prepareStatement(statementSql);
169             try {
170                 for (EventSource eventSource : events.keySet()) {
171                     Set<Event> eventData = events.get(eventSource);
172                     for (Event event : eventData) {
....
181                         ps.setString(paramIndex++, event.getDetail());

However, then the database (oracle in our case) has not been setup to use UTF-8, but only a standard 8-bit character set then trying to insert a "detail" which has international (e.g. 16 bit) characters in it will break the 4000 limit with:

ORA-01461: can bind a LONG value only for insert into a LONG column

because the number of bytes form the "detail" will be bigger then 4000.

Solution:

- make the database being UTF-8 a requirement (JON installer to check)

or modify the above code:

  byte[] detailBytes = event.getDetail().getBytes();
  ps.setBytes(paramIndex++,Arrays.copyOf(detailBytes, 4000));
