We only use put.
We do call to the cache in a synchronised method. This is how we call the
cache.
public synchronized Object put(String fqn, Object key, Object value)
throws CacheImplementationException {
| if (isCacheActive()) {
| try {
| StringBuffer buffer = new StringBuffer();
| buffer.append(fqn);
| buffer.append(FORWARD_SLASH);
| buffer.append(key.toString());
|
| HashMap<String, MarshalledValue> map = new
HashMap<String, MarshalledValue>(1, 1.0f);
| map.put(key.toString(), new
MarshalledValue(value));
|
| return server.invoke(cacheService, "put",
| new Object[] {
buffer.toString(), map },
| new String[] {
String.class.getName(), Map.class.getName() });
| } catch (Exception e) {
| e.printStackTrace();
| throw new CacheImplementationException(e);
| }
| }
| else {
| return null;
| }
| }
Do we need to have this synchronised? In our TreeCache setup we set the
SyncReplTimeout to 10000ms.
The first dump we posted looks like it is blocking in
org.jgroups.blocks.GroupRequest.doExecute(GroupRequest.java:492) which is
jgroups itself. Are we reading this right?
