I should mention that I've had a much more stable experience with 8.1.6.

Rolling something into production tomorrow. Unfortunately, our production volume is so high I can't generate a realistic test on my development machine, but I _think_ it will work. I'll post a real answer on Friday after we've had a few days to observe. Following up my prior post, though, I was...

Okay, this is just strange. I did my own pooling and I've been testing it on my desk for the last week. Today I needed to get the window out of the way and I minimized. My memory charge dropped like a stone; well below the initial launch. Then it started creeping back up. Restoring had no...

I did my own benchmarks to make sure they were relevant to what I was doing. Comparing a recent build of DOA to BDE 5.something, I found that ... - Connections were established about 0.25s faster with DOA. (Down from 250ms to about 10ms.) - The overhead of calling a stored procedure dropped by...

I'll be looking forward to hearing how that turns out. Anything I can do in the meantime to facilitate investigation? Alternatively, any thoughts on a workaround that might at least slow the leak? G

Distinctly not okay. I've got, for the moment, an evaluation copy of MemorySleuth and it's flagging calls to TOracleSession.Logon. Additionally I put a new build out yesterday that uses DOA's internal pooling - and no other changes - and my leakage has doubled.

Have an app processing tens of thousands of transactions daily. Each transaction is processed by a newly-spawned thread that creates a data module containing a session and multiple queries. Any given transaction will use 1-3 of the query objects. Sessions are not pooled. Had been having AVs and...

Upgraded to OCI 8.1.7 yesterday. Put back the DOA-based client program today and things are worse. Access Violation in orageneric8.dll as soon as transactions start flowing in. I see a few other posts related to that kind of behavior in threaded apps, but nothing for quite some time. Any pdate...

Haven't tried on Net8 yet. Read the referenced bug topic. It happened again today, after about a 22-hour uptime. Seems to have occured on TOracleSession.Commit, because I've got an exception handler like: try myQuery.Execute; mySession.Commit; except // dumps SQL and argument list end; The...

Threaded program, with each transaction spawning a thread and each thread creating a data module with a dedicated OracleSession and multiple OracleQuery objects (some subset of which will actually be used). 19 hours post-launch, I get ORA-03115: unsupported network datatype or representation...

Just added the code to do that. Hopefully I'll have a rollout scheduled for this week. G

Platform = NT4SP6a DOA version = 3.4.6 Tool chain = Delphi 4 Update 3 The application is threaded, with transaction spawning a thread which instantiates a data module containing a session and several query objects. Most of the queries are set up design time, but I keep one around for more...

Happened twice last Friday (with a reboot in between). The first time, every message referenced address 0FA09FE7. The second time, they were at 10019FE7. As I go back through the logs, it seems to always end in 9FE7 and it's always consistent within one run of AV's.
