[JBoss JIRA] (TEIID-4205) send results proactively under a cursor as it looks like the ODBC client requires a transaction.
by Steven Hawkins (JIRA)
[ https://issues.jboss.org/browse/TEIID-4205?page=com.atlassian.jira.plugin... ]
Steven Hawkins commented on TEIID-4205:
---------------------------------------
Now my approach will be to disable the implicit use of transaction wrapping around an odbc cursor.
This is much simpler as we'll look for "BEGIN;declare " and strip off the BEGIN. I would like to make this default behavior given that we are also ignoring the associated savepoint/release. We can also add a switch to allow the transaction to be honored.
[~rareddy] or others have thoughts on this?

[JBoss JIRA] (TEIID-4205) send results proactively under a cursor as it looks like the ODBC client requires a transaction.
by Steven Hawkins (JIRA)
[ https://issues.jboss.org/browse/TEIID-4205?page=com.atlassian.jira.plugin... ]
Steven Hawkins commented on TEIID-4205:
---------------------------------------
The change to allow results to flow under a transaction are easy but reverted due to:
* lob values cannot be read concurrently with the usage of their underlying connection, which is easy to workaround by copying the lob, or alternatively we can move the processing onto the main workitem
* there isn't a good notion of statement completeness. from the spec there are competing definitions of when a statement is complete - either when the result set has been fully read or when the result set has been closed. In our case "when the result set is closed" is somewhat inconsistent as we are proactively producing some number of rows (although this could be explained as an extension of the fetch size). The current behavior of completing processing ensures statement completeness in a way that does not depend on how much of result set the client reads. In the xa/local case we may also need to account for commits that happen concurrently with processing - which doesn't happen now either.

[JBoss JIRA] (TEIID-2132) Teiid 8.0 API does not expose boundport in Mbean attribute for Teiid-JDBC

> In above line if I set the value as 25 then that should be added to the default socket port values and exposed as bound port value in MBean server. But in case of teiid the "teiid-jdbc" 's boundPort value is not exposed by the jboss.

> All other boundPorts values are correctly shown in Mbean, except teiid-jdbc

Summary: Limit pushdown is incorrect for simpldb

Project: Teiid
Issue Type: Bug
Components: Misc. Connectors
Affects Versions: 8.7

Fix For: 9.0, 8.12.5, 8.13.5
The limit clause for simpledb sets a page size rather than fully limiting results, thus our pushdown is incorrect.

[JBoss JIRA] (TEIID-4130) Prevent blocked exceptions from being thrown in AccessNode open
by RH Bugzilla Integration (JIRA)
[ https://issues.jboss.org/browse/TEIID-4130?page=com.atlassian.jira.plugin... ]
RH Bugzilla Integration commented on TEIID-4130:
------------------------------------------------
Juraj Duráni <jdurani(a)redhat.com> changed the Status of [bug 1326832|https://bugzilla.redhat.com/show_bug.cgi?id=1326832] from ON_QA to VERIFIED
> Prevent blocked exceptions from being thrown in AccessNode open
> ---------------------------------------------------------------
>
> Key: TEIID-4130
> URL: https://issues.jboss.org/browse/TEIID-4130
> Project: Teiid
> Issue Type: Bug
> Components: Query Engine
> Affects Versions: 8.7
> Reporter: Steven Hawkins
> Assignee: Steven Hawkins
> Fix For: 9.0, 8.12.5, 8.7.6.6_2, 8.13.4
>
>
> Having the access node block in open can lead to unintended consequences in parent nodes. For example with tuplesource caching it can create additional tuplesource instances such the cached source is closed prematurely (as it thinks that all readers have been satisfied). This results in exceptions similar to:
> TEIID30019 Unexpected exception for request 2TLgULsEBZvO.8: java.lang.AssertionError: ASSERTION FAILED: expected reference to be not null
