I noticed this problem with straight SQL too (insert / update) ... If I open connection with autocommit(false), and then try to commit / rollback; I get the same error

However, I'm using straight SQL. I'm not sure this is the issue, but I am using the N+1 technique to add child records to the master.

We're using connection pooling and so far so good. So now I'm trying to use the same connection pools for batch applications that are scheduled to run via a chron type function from the same webserver. Those jobs run fine on our development boxes without connection pooling (i.e., as Junit processes). But when I try to run them from the webserver, I get a few of these errors and then all the connections become useless quickly and I have to restart the webserver. The errors start with the message: Unable to set AutoCommit property.SET CHAINED command not allowed within multi-statement transaction. Then as the connections become useless, the following messages start coming out. This message I would expect after the pool is exhausted. Error in allocating a connection. Cause: In-use connections equal max-pool-size and expired max-wait-time. Cannot allocate more connections What's really perplexing me is that this happens on SELECT statements, and not just INSERT or UPDATE statements. I've Googled this error and am not getting anywhere. I've also reviewed the connection pool settings and no amount of tweaking improves the situation. Any help would be most appreciated. Our environment consists of: Java 1.6 Spring 2.5 Ibatis Glassfish/ Sun Java System Application Server 9.1 (build b58g-fcs) (webserver) Sybase 12.5 ________________________________ This email is confidential and subject to important disclaimers and conditions including on offers for the purchase or sale of securities, accuracy and completeness of information, viruses, confidentiality, legal privilege, and legal entity disclaimers, available at http://www.jpmorgan.com/pages/disclosures/email.
