Steven Hawkins resolved TEIID-4477.
-----------------------------------
Fix Version/s: 9.1
9.0.5
Resolution: Done
Updated the isAlive method so that the pool can properly remove stale connections when the
validate-on-match or background-validation is configured. Also allowed the context
factory to be set and added null checks to prevent the npe on close when execute fails.
LDAP connector disconnects intermittently with error
"TEIID12002"
-----------------------------------------------------------------
Key: TEIID-4477
URL: https://issues.jboss.org/browse/TEIID-4477
Project: Teiid
Issue Type: Bug
Components: LDAP Connector
Affects Versions: 8.12.5
Environment: Red Hat JBoss Data Virtualization - Version 6.3.0
Reporter: Rafael Coutinho
Assignee: Steven Hawkins
Fix For: 9.1, 9.0.5
We are using LDAP connector for virtualizing the ldap employee directory data. For some
reason every 3 to 4 hours we get a connection error between JDV and LDAP.
The exception says it could not find the context name, but after restarting it it works
again.
Here is the exception:
11:21:12,868 WARN [org.teiid.CONNECTOR] (Worker62_QueryProcessorQueue108177) Connector
worker process failed for atomic-request=6S71mw5pkfvo.106.3.19906:
org.teiid.translator.TranslatorException: TEIID12002 Failed to create LDAP search context
from the specified context name ou=users,dc=redhat,dc=com. Check the table/group name in
source to ensure the context exists.
