Re: Problem in resultMap:Cause: java.sql.SQLException: Invalid state, the ResultSet object is closed
I noticed there are only two tables involved, could you try with some different database engine ? If you still get similar exception, one should start inspecting your code/iBatis code, if not, definitely it's a driver/db server problem (try different driver)...
Re: iBATIS querying pattern for web applications
Can your query raise exception that's handled elsewhere, so that
session.close() is not called? Try this:
SqlMapSession session = sqlMap.openSession();
List list = null;
try {
list = (List) session.queryForList(queryId);
}
catch (Exception e)
{
log.
}
finally {
session.close();
}

Re: iBATIS querying pattern for web applications
Can you look from another side, i.e. check database sessions when the the
exception occurs. I'd look at last sql executed in those sessions to find
if there's same sql that's stuck or long running. It could tell you which
part of your code to check... Last time I've seen that exception it was pure
JDBC where a guy forgot to close a statement and most of sleeping database
connections showed that statement was the last one.

So, the possibility of leaving sessions open is strange, as there are no
more than 1 request at a time, as the queries are very simple and with small
result sets, so the life period of sessions should be very short, less than
a few seconds maybe.

Inserting lists
/* I apologize for re-posting this, but I think my previous post ended in junk folders because I was using all-numeric mailbox */ Recently I found that I'm writing loops to insert lists of objects way too often. I think it makes sense implementing methods like: insertList(insertSingleSomeObject,ListSomeObject)(with insertSingleSomeObject beeing sqlmap entry for inserting single object, which I have to use in loops) batchInsert(insertSingleSomeObject,ListSomeObject) (with batch size configurable like row prefetch is) updateList(updateSingleSomeObject,ListSomeObject) batchUpdate(updateSingleSomeObject,ListSomeObject) Think it will make iBatis more consistent: we have queryForList, i.e. getting list of objects in a single line of code, so it's quite natural to expect that one should be able to persist the list in a single call. Wonder what others think about it. Nicholoz Koka Kiknadze
Re: Inserting lists
Jeff, Just for an argument ;) -- you are understating powers of iBatis ;) iBatis can return list of objects running multiple susbselects for each row (property column= select= / ) - something you'd have to do manually in pure JDBC. In fact, I'd go further allowing inserting object with list properties in a single sqlmap method using somethimg similar to subselects, but thats another story. I understand you philosophy, but I'm trying to look from practical point of view - the less boilerplate code in my app, the happier I am, quite a selfish approach ;)
Re: Help with what commitRequired=true param means
Here's extract from iBatis docs:
*Normally iBATIS will not commit transactions unless an insert, update, or
delete operation has been
performed. This is true even if you explicitly call the commitTransaction()
method. This behavior
creates problems in some cases. If you want iBATIS to always commit
transactions, even if no insert,
update, or delete operation has been performed, then set the value of the
commitRequired attribute to true.
Examples of where this attribute is useful include:
1. If you call a stored procedures that updates data as well as
returning rows. In that case you would
call the procedure with the queryForList() operation – so iBATIS
would not normally commit the
transaction. But then the updates would be rolled back.
2. In a WebSphere environment when you are using connection pooling
and you use the JNDI
dataSource and the JDBC or JTA transaction manager. WebSphere
requires all transactions on
pooled connections to be committed or the connection will not be
returned to the pool.
Note that the commitRequired attribute has no effect when using the EXTERNAL
transaction manager.
*
So it does not explain why your transactions are not commited with
commitRequired=false if you do call commitTransactio() after
insert/update/delete (and I think you do not care about commiting after
selects).
Could you provide sample transaction code from your app which you suspect
does not commit ?

First of all I'd add catch block to log errors to your try/finally. In your code you do multiple inserts, so if any of them fails your whole transaction will roll back. I can see no other possible scenario :(

Re: IBatis 2.3 lazy loading issue for return null instead of an list
AFAIK the root of the problem is that when iBatis handles resultset of left
joining master table with child table the child table columns may be all
NULL and it's not quite clear whether child table indeed contained
corresponding row with NULL elements or there was no result found in the
child table. Hence it adds a single element (with NULL values) to the list.
So i think it's not lazy loading issue at all.
Hence in such situations I add a check in my DAO layer and discard the child
list if it contains single element with all NULL values. Wish iBatis could
handle this for me through, say, some boolean flag 'discardNullChildLists'.

Hi,
I use the feature Lazy loading for IBatis2.3, I have a domain class like:
public class Role(){
private String id;
private String name ;
private ListPrivilege privilegeList ;
}
the problem is:
when the privilegeList is not null, I mean a Role object has more than
one Privilege, ok, everything goes well.
But when the Role doesn't has any Privilege, I hope my Dao could return
null for the property privilegeList. When I debug my program, I found
it's stranger, the privilegeList is not null, it is a List with one
element, the only one element is Privilege Object but doesn't have values.
I try to google the issue and find this:

Re: Question on iBatis Implicit Transactions ?
2b) Scenario: copy/pasting from manual: __ The transactionManager element also allows an optional attribute * commitRequired* that can be *true* or *false*. Normally iBATIS will not commit transactions unless an insert, update, or delete operation has been performed. *This is true even if you explicitly call the commitTransaction() method*. This behavior creates problems in some cases. If you want iBATIS to always commit transactions, even if no insert, update, or delete operation has been performed, then set the value of the *commitRequired* attribute to *true*. Examples of where this attribute is useful include: 1. If you call a stored procedures that updates data as well as returning rows. In that case you would call the procedure with the queryForList() operation – so iBATIS would not normally commit the transaction. But then the updates would be rolled back. _ So yes, iBatis will rollback. 2a scenario: if you forget to call endTransaction iBatis will do nothing and sooner or later your connection pool will get exhausted. Copy/pasting again: ___ Notice how endTransaction() is called regardless of an error. This is an important step to ensure cleanup. The rule is: if you call startTransaction() be absolutely certain to call endTransaction() (whether you commit or not). ___ 1a: Again some little copy/paste ;) ___ Although using explicit transactions is very highly recommended, there is a simplified semantic that can be used for simple requirements (generally read-only). If you do not explicitly demarcate transactions using the startTransaction(), commitTransaction() and endTransaction() methods, they will all be called automatically for you whenever you execute a statement outside of a transactional block Not sure, but think COMMIT_REQUIRED applies here also, i.e. iBatis will rollback after any SELECT statement unless COMMIT_REQUIRED=true Try to use docs from SVN, nowadays they contain far more info than they used to couple of years ago ;) On Tue, Nov 25, 2008 at 10:43 PM, mfs [EMAIL PROTECTED] wrote: Hello Guys, I have got a couple of questions relating to iBatis starting out implicit trasactions..Let me add that i am using iBatis JDBC TransactionManager.

If that is true would iBatis commit the transaction in the end (given we never started one mistakenly or otherwise and hence not committing/rolling-back) ? 2a) Second Scenario. We do start a transaction but don't explicitly do a commit in the end.

if i don't set the setter method of the keyword-column property in a
javabean,then i can't delete it using this property?
for example:
the javabean:
public class JobPosting implements Serializable {
private int jobPostingId;
//missing other properties...
...
public int getJobPostingId() {
return jobPostingId;
}//only the getter method
//missing other getter/setter methods
...
}
the xml:
delete id=deleteJobPosting parameterClass=JobPosting
delete from jobPosting where jobPostingId=#jobPostingId#
/delete
the java code:
public void deleteJobPosting(JobPosting j) {
getSqlMapClientTemplate().delete(deleteJobPosting, j);
}
i have tested it can't be deleted in this case,there is also no error
messages,but i can insert with the same model, anyone knows why?
thanks in advance

Re: [SURVEY] How many connections are in your pool?
Hi Sundar, I am not an hardware expert, but I suspect that even with modern dma access etc if you ask your CPU to process N database transactions (initiated by different users) in parallel it may take longer compared to when you ask it to do them consequently. So quite possible that pools with connection number CPU number induce performence penalties. In other words the time your pool waits for a connection to get available in the pool is just caused by your hardware (CPU) beeing busy, so why add extra latency with extra pool code... Again, of course the logic can not applyed to long running transactions when CPU is idling in the midst of transaction waiting for e.g. extra user input.

If there are no warnings about unsupported data types, then my best
guess is that the column got added to a table that is not in the

I'd recommend attaching the Abator source and debugging - put a
breakpoint in the getColumns method of

be able to see if the column is returned to Abator from the JDBC

Re: mysql default value
I do not like idea of keeping defaults both in database and application.
If I have a not nullable database field with some default value, besides
setting default value in database I use 'before insert' table trigger that
checks if supplied value is NULL and sets it to the desired value.
Well, I believe database vendors should treat not-null fields with default
values in that way saving me from writing those tedious triggers ;)

Re: Cannot serialize session attribute ...
I have never used tomcat clustering, but it sounds to me reasonable that disabling persisting sessions upon tomcat exit has nothing to do with clustering. However, in order to replicate session object in clustered environment the session object *has to be* serializable. So, imho, any reference to singleton objects in your session can be and must be marked with 'transient'.

Re: How to Compare database record before UPDATE using iBatis?
No I think. iBatis is not aware whether your VO-s have changed and can not decide whther to run updates or not. Why don't you override the Object.hashcode() method on your VO and call it and save the value when you retrieve the record. Call it again when the user submits their changes. If the values are different, the a change was made. Hm, I usually override equals. Any advantages with hashCode? But most of the time (being lazy) I execute updates without checking if there were atual changes. You know modern hardware and database software are so fast.

When I push the code out to my test server (more powerful hardware, etc.), the method takes 10 or 11 seconds. So, I'm trying to figure out if the extra time is occurring on the database server or on the application server. So, I turned up all the logging and I looked at what it is spitting out at me. Of course, takes a bit longer with logging turned on, but not hugely so. I looked at the times of the different statements, and the 'About to execute SQL' log statement shows up at second 0. The next line of the log file is each row of the result set. This is logged in the same 'second' as the line of the 'About to execute'. The next 2000 rows in the log are each of the lines of the result set and it takes 9 or 10 seconds for this to occur. My question is, is this an indication of the database slowly returning the data, or does iBatis really get all of the data back to the application server by the time that first result set record is logged and it really is taking iBatis 10 seconds to go through data on my review server that takes 2 seconds to go through on my dev server. This is a 'hierarchical' query (if that makes sense). The data is in the form of product information and product attribute information. I am using the iBatis 'groupBy' clause in the resultMap to tell iBatis which columns constitute the objects lower down on the hierarchy. Does it makes sense that iBatis would take this long to process the data? Should I look at writing a RowHandler to process this data?

Re: Identify the record that caused unique constraint violation
It may be database dependent. Here's extract from oracle docs http://download.oracle.com/docs/cd/B10501_01/java.920/a96654/oraperf.htm After a batch exception, the update counts array can be retrieved using the getUpdateCounts() method of the BatchUpdateException object. This returns an int array of update counts, just as the executeBatch() method does. In the Oracle implementation of standard update batching, contents of the update counts array are as follows after a batch exception: - For a prepared statement batch, it is not possible to know which operation failed. The array has one element for each operation in the batch, and each element has a value of -3. According to the JDBC 2.0 specification, a value of -3 indicates that an operation did not complete successfully. In this case, it was presumably just one operation that actually failed, but because the JDBC driver does not know which operation that was, it labels all the batched operations as failures. You should always perform a ROLLBACK operation in this situation.
Re: date doesn't include hours, minutes, seconds
IBatis creates this select:
to_date('2009-05-15 23.59.59', '-mm-dd hh24.mi.ss')
Well, there's no to_date function in your XML, so iBatis can not create it.
It only prepares statement (ps) with
AND b.ins_time = ?
AND b.ins_time = ?
and calls ps.setDate
Could you re-check your xml files and re-check iBatis logs, I'm sure iBatis
is not 'smart' enough to add Oracle-specific to_date functions to generated
sql.

Re: FW: Connection Closing Problem
I think what happens to open (pooled) connection upon JVM exit depends on JDBC driver. IMO if you were using SimpleDataSource of iBatis, you'd have to call forceCloseAll() to close all pooled connections at the end of execution of your app (I think I have even used that years ago). Not sure about DBCP, but I bet calling basicDataSource.close() must help. GL On Wed, Jun 3, 2009 at 12:18 AM, Nathan Modrzewski nmodrzew...@eaglexm.comwrote: Not yet…getting ready too.

Re: help to reduce db round-trip
I think the only reliable way to check whether connection is valid is to execute something using the connection (so it requires roundtrip to db). However a) this execution happens only once for your transaction (which may include numbers of CRUD operations etc) b) Validation query is chosen to be simple (like select 1 from dual for oracle), so that performance penalty is minimal. So IMO unless you are designing some realtime application you can stop worrying about additional roundtrip stealing maybe a dozen of milliseconds...

Which means that I receive rubbish.
What can I do to handle it?

Re: Prepared Statement cache
Maybe I'm totally wrong, but I'm almost sure it must be possible to force database server to RE-generate execution plans even for cached statements. I've never used DB2 but googling a little I found: http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=/com.ibm.db29.doc.ugref/db2z_invalidatestatementscache.htm HTH
Re: PL/SQL package level variables
You are quite right. Your problem is that calls to those two procedures are not in a single transaction. Include them in a single transaction and proc2 will see package level variables set in proc1. Note that executing those procs on a single connection object is not enough (i.e. you need transaction). hth On Tue, Aug 4, 2009 at 8:48 AM, CuriousMind yogeshcjad...@hotmail.comwrote: Hi, I am having 3 procedures which i want to call using IBatis framework. These procedure are using package level variables and hence when I try to call them, it ends up throwing error as the package variable value is not found. Consider following scenario for more details Package level variable = varPK Procedure 1 sets varPK (Package level variable) to SomeValue Procedure 2 tries to check value of varPK and finds that it is empty. I know this could be resolved by writing wrapper procedure which will call above listed procedure in sequence but I am looking for better solution. The problem is that I am migrating existing application to Ibatis framework and hence it is not possible to find out where such scenarios would come. The error that I am facing is probably due to for every call to iBatis API gets different connection object (I am using connection pool and spring integration with ibatis.). I think this can be resolved only if current thread will get same connection instance. Is there any way to ensure that the current thread will always receive same connection instance? -- View this message in context: http://www.nabble.com/PL-SQL-package-level-variables-tp24802267p24802267.html Sent from the iBATIS - User - Java mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-java-unsubscr...@ibatis.apache.org For additional commands, e-mail: user-java-h...@ibatis.apache.org
Re: PL/SQL package level variables
Hm, but I have used package variables at Oracle 9 times (with JDBC though, but iBatis just wraps JDBC) and it worked fine. May I ask how do you handle transactions, and may I look at the code snippet calling those procedures?

Separate iBATIS3 mailing list
I've enjoyed much using iBatis and the mailing list was always very helpful. Well, now and then I have to search for answers in the mailing list and usually find the answer ;) So far so good. But... I've used mailing list for another framework - Tapestry for three major versions (3/4/5) and always found it very annoying not to be able to filter for which version I needed to search. Now, as questions about iBatis3 start to pore in I wondered maybe in long run it may be better to have separate mailing list for it. I don't mind subscribing to two lists - my gmail inbox will handle both ;) Wonder what others think...
Re: PL/SQL package level variables
Honestly, I don't quite understand your config. You have tx:annotation-driven transaction-manager=txManager / So I guess you use annotations to mark transactions. In that case you all that advice/pointcut stuff seems redundant. Now as you do not set proxy-target-class=true dont forget that you need to put Transactional annotations at the interface level.

Re: Separate iBATIS3 mailing list
#3 - I think I'm the only person who does moderation on the ibatis lists and don't want another one to manage. (NOTE: If someone wants to do that with me, let me know, it's easy, but when I'm out of the office the please subscribe emails pile up). I'll be out of the office till September 6 (hehe, don't worry I have autoreply off). Meanwhile as I watch this list almost on the daily basis I could help in handling those out-of-the-office-please-unsubscribe-enlarge-something things after that. Or what else does moderation mean?
Re: Problem calling Stored function in Oracle
Though I've never used oraclecursor with iBatis, I'll dare to note that
from the image attached I see that parametermap property for the
ORALECURSOR is the last one in the map.
But it must be the first one (order parameter map properties must match
order of ?,?... ).
