Re: DB changes not reflected in CMP bean.
Thanks! It works great now. Made the changes in orion-ejb-jar.xml and any updates to the db by other sources is pretty much updated instantly. Does anyone knows if this feature is stated in the EJB standards?

RE: DB changes not reflected in CMP bean.
This is a very interesting question. A lot of sources claim that the update of beans should be automatic. Otherwise how would you connect the application to any legacy database system which can be updated bypassing the beans. We've just only started with Orion so I don't know the answer yet but will do some research. Also a kind request: could you tell us what needs to be done to connect Oracle to Orion (we run 8.1.5 on NT)?

RE: DB changes not reflected in CMP bean.
You need to set "exclusive-write-access" to "true" (this slows the CMP down because it checks the DB before every operation for a write). -mike -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jarek Skreta Sent: Friday, November 24, 2000 8:49 PM To: Orion-Interest Subject: RE: DB changes not reflected in CMP bean.

RE: DB changes not reflected in CMP bean.
Winston, The good news is that the beans do get updated automatically in the CMP model on Orion. At least when we run the CMP Primer example. Not quite sure why your set up does not work. Is it possible that they get updated after a long delay? In that case it could be something to do with setting transactions.

RE: DB changes not reflected in CMP bean.
Hi, We are using Oracle 8.1.5 with NT 4. It all runs on the same box. Maybe by chance but we managed to connect first time. Here are some settings which may be of help: 1. We use ODBC with Oracle ODBC driver. 2. tnsnames.ora entry for the service used by ODBC: ORASERV1 = (DESCRIPTION = (SOURCE_ROUTE = OFF) (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(Key = oraserv1)) (ADDRESS = (PROTOCOL = TCP)(HOST = compserv01)(PORT = 1521)) (ADDRESS = (PROTOCOL = NMP)(Server = compserv01)(Pipe = ORAPIPE)) ) (CONNECT_DATA = (SID = oraserv1) (SRVR = DEDICATED) ) ) where: 'oraserv1' is the database SID, 'compserv01' is server's name Your listener should be configured to use any of these protocols. Possibly all of them. 3. Settings used in data-sources.xml data-source class="com.evermind.sql.ConnectionDataSource" name="Oracle" location="jdbc/DefaultCoreDS" xa-location="jdbc/xa/DefaultXADS" ejb-location="jdbc/DefaultDS" connection-driver="sun.jdbc.odbc.JdbcOdbcDriver" username="danny" password="murphy" url="jdbc:odbc:yourdsn" inactivity-timeout="30" / where 'yourdsn' is the ODBC DSN name. Hope this is of help. Jarek -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John N. Alegre Sent: 24 November 2000 19:40 To: Orion-Interest Subject: Re: DB changes not reflected in CMP bean. We have got this to work on Oracle running on Solaris and Linux. All attempts to use Oracle 8.1.5 on NT are failing. The error returned by Orion shows a failure in TNS lookup. However, we can write straight Java JDBC code and connect just fine. sqlnet also connects just fine using the same URL and driver. The failure only occurs on NT Oracle with Orion. I would be glad to elaborate with error codes and sample Java source files if desired. Is anyone using Oracle on NT with Orion?
