    JDBCCacheLoader with Oracle 10g problem

    xuetao niu Newbie

      Hi,

      I am using JBossPojo Cache 3.0.0.GA and evicting cache to oracle 10g using JDBCCacheLoader shipped with JBoss. But when I run it with 1 thread, I always see such exception:

      Caused by: java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column

      If I run it with multiple threads, I get this exception, which looks like jboss is trying to recreate the same table for twice:

      I didn't manually create the table in Oracle at all. Has anyone encountered this before?

          Can you please take a look at the created table in Oracle and post its structure/DDL (IIRC you can use DESC <table_name> for that).

          • 2. Re: JDBCCacheLoader with Oracle 10g problem
            xuetao niu Newbie

            Thanks Mircea,

            Here is the table description:

            DESC cached_events
            Name Null Type
            ------------------------------ -------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
            FQN NOT NULL VARCHAR2(255)
            NODE BLOB()
            PARENT VARCHAR2(255)
            
            3 rows selected
            


            And there is another table automatically created, called 'cached_events_d' which is not described in the jboss doc as far as I can find. And if I change the cache table's name to something else, say XXX, the automatically created table will be named as XXX_Y where Y looks a random character.

            Do you know what this is for?

            The description of this table is as below:
            DESC cached_events_d
            Name Null Type
            ------------------------------ -------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
            I CHAR(1)
            
            1 rows selected

              The table looks okay.
              Can you please take a look(post) in the logs for the debug statement right before the failure. Should look like this: "executing sql: INSERT INTO...". Also try execute that from the console, perhaps we can narrow down the problem this way.

              JBossCache does not generate such a table, most likely it is generated by RDBMS

                Hi Mircea,

                Thanks for the hints, I looked at the debug log, the sql statement being logged right before the exception is not a "INSERT INTO, but a select":

                
                DEBUG JDBCCacheLoader - executing sql: select fqn from Cached_Events where parent=? (/)
                
                


                I tries to execute the statement: select fqn from Cached_Events where parent='/', it finds something in the table.

                The 1st insert into statement is logged far after the exception is logged. This is the log msg for it, and it is surprisingly involving the automatically created table 'cached_events_d':
                DEBUG JDBCCacheLoader - executing sql: INSERT INTO Cached_Events (fqn, node, parent) SELECT ?, ?, ? FROM Cached_Events_D WHERE NOT EXISTS (SELECT fqn FROM Cached_Events WHERE fqn = ?) (/RTDE/time-distance-analysis-gps/0)
                


                I don't know how to execute this in the console (Oracle SQL Developer)

                Any idea?

                  Btw, I was testing with 5 threads when seeing the DEBUG logs above.

                  I also tested with 1 thread, bug with DEBUG level on "org.jboss", I cannot recreate any exceptions. However, with WARN debug level for "org.jboss" I still can reproduce it as described on my original post. Weird...

                    No, sorry, I managed to reproduce the problem with one thread on DEBUG level. Here is the log:

                    [2009-07-01 16:11:48,367] [Detection1] DEBUG JDBCCacheLoader - executing sql: INSERT INTO Cached_Events (fqn, node, parent) SELECT ?, ?, ?

                    Still don't know how to fill in the question marks to run it...

                      And the error log from JDBCCacheLoader right after this debug log is this:

                      [2009-07-01 16:11:48,367] [Detection1] ERROR JDBCCacheLoader - Failed to insert node :ORA-01461: can bind a LONG value only for insert into a LONG column
                      

                      And the error stack trace is the same as I posted on the top floor of this thread.

                        yep, I've just noticed that the cache loader was modified to create a new table postfixed with "_D", so Cached_Events_D is indeed created by jbosscache. This was a changed made for following JIRA JBCACHE-1410. Guess the query (which looks a bit odd to me) doesn't work on oracle. Is this happening from the start, when you firt try to add something to the cache, or only after a while?

                          Hi Mircea,

                          Thanks for the response.

                          Do you mean the version I am using does not work for Oracle?

                          I actually have two problems:

                          1. Running with 1 thread, as pasted above, there are 3 exception traces logged by JBossCache at both WARN and ERROR level, they are not thrown by JbossCache as runtime exception. But these logs contain the exception stack trace which seems internally handled by JbossCache, but I am not sure what JbossCache does except for logging only.

                          These log messages happen a short while after I put something into pojo cache, and not to each put I do.

                          These messages are related to transactions. They are pasted below:

                            The 2nd problem I have occurs when running with multiple threads. This is a runtime exception being thrown, not a log message. (besides the 1-thread problem still arises in multiple thread environment)

                            This problem appears differently in JSE environment (where only DummyTransactionManager is used), and in Websphere6.1.

                            The exception stack in JSE environment was pasted on the 1st floor of this thread. The stack trace of running in Websphere6.1 is pasted below:

                            I checked the Javadoc of GenericTransactionManagerLookup class, it does not say Websphere6.1 is supported, could this be the problem? I will try to run it on Glassfish2 to see what happens.

                              as the stack trace shows, both exceptions originate within the JDBCCacheLoader, and are most likely related to a change that was made to it, regarding https://jira.jboss.org/jira/browse/JBCACHE-1410. I've reopened the JIRA to test Oracle 10g integration.

                                Thanks Mircea, can we expect any forseeable date of this issue being tested and solved if it is really a bug?

                                  Btw, can I use the GenericTransactionManagerLookup in Websphere6.1?

                                    It should do.
