BPM Studio-Issue with Creating External Resources - Oracle Database RAC

Question

Hi All,
This must be an easy fix and hope you guys have an answer to it. I was having no issues connecting to a single instance database as the parameter Host = "xxx.111.200.10" for a SQL Database Oracle 10,11 driver is pointing to a single instance and the SID = "yyyyy". TNS Name entry is as below...
xyz =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxx.111.200.10)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = yyyyy)
However we have upgrade our oracle database and it is in a RAC with load balancing hence the TNS Name entry looks like this.
xyz =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abcdh-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = abcdi-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = yyyy.abcd.com)
Any combination using "xyz", "abcdh-vip" , "abcdi-vip" etc is erroring and I am getting the following error:
[BEA][Oracle JDBC Driver]Error establishing socket. Unknown host: abcdh-vip
java.sql.SQLException: [BEA][Oracle JDBC Driver]Error establishing socket. Unknown host: abcdh-vip

Any help would be highly appreciated.

Hi,
Sure you've probably tried this but here goes...
Use the Oracle Driver that comes with Oracle BPM to integrate with RAC.
To integrate to Oracle RAC, you're typically given something like this by the DBA.
jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = atwood-vip.int.westgroup.com)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = kenwood-vip.int.westgroup.com)(PORT = 1521)) ) (CONNECT_DATA = (Service_name = bpms_pot_dev.int.westgroup.com) (SERVER = DEDICATED) ) )
When defining the External Resource for Oracle RAC check the “Advanced” checkbox (not the tab) and insert this text into the “Database” field:
//atwood-vip.int.westgroup.com:1521;ServiceName=bpms_pot_dev.int.westgroup.com;LoadBalancing=true;AlternateServers=(kenwood-vip.int.westgroup.com:1521)
Hope this helps,
Dan
