I added this to the tranql wrapper and pushed a new snapshot to the
codehaus snapshot repo.
http://snapshots.repository.codehaus.org/org/tranql/tranql-connector-informix-xa/1.2-SNAPSHOT/
Can you verify that this works, that the time unit is seconds, and
look around to see if there are other properties we should allow
setting on the XADatasource?
many thanks

Hello everyone, We are using Geronimo 2.1.4 with informix XA driver
version 3.0.0 JC3. The application we build has a process which runs
in the geronimo containner every 2 minutes and updates lots of
tables. in foreground we a web application where users can access
screen and update and retrieve from the same tables. Our
architecture is like this JSP/Struts 2 --> EJB 3.0 with CMT--> DAO
using hibernate uses data source configured in geronimo server-->
informix DB We have configured the data source using the informix
provided drivers and the informix Tran QL connectors. We are
currently facing a problem where we are getting locking issues
frequently when the user and batch process collides. The error is
"Could not do a physical-order read to fetch next row.SQL Error:
-107, SQLState: IX000" The solution provided was to increase the
IFX_LOCK_MODE_WAIT to some reasonable time so that the process waits
for the predefined time before it throws the error. Default value
for this is configured as zero in IFXDatasource. By default data
source configured using the informix XA option does not have any
option to configure this parameter. Neither the hibernate has any
configuration for this, as it is using the data source created in
application server. On analyzing the source code we noticed that
there is a component org.tranql.connector.informix.XAMCF part of
tran QL adapter which creates and configures the data source, public
XAMCF() { super(new IfxXADataSource(), new
NoExceptionsAreFatalSorter()); password = ""; ds =
(IfxXADataSource)xaDataSource; } This IFXData source doesn not have
the option of lock mode wait setup, which can be done using the
method "setIfxIFX_LOCK_MODE_WAIT". My questions are: 1. Is there any
option where in we can configure the IFX_LOCK_MODE_WAIT parameter?
2. If not is there any patch with this enhancement done. Thanks in
advance Best Regards Shanmu
