Oracle: Io exception: Got minus one from a read call

[shruti]

Hi,

I am trying to connect to a oracle database which is load balanced but unable to connect due to the below error:


Connection details:

Driver: oracle.jdbc.OracleDriver ( v1.0)
Driver URL: jdbcracle:thin:@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xx.x.xxx)(PORT = 1523))(ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xx.x.xxy)(PORT = 1523))(LOAD_BALANCE = yes)(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = test)(FAILOVER_MODE =(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))

User Name: test
Password: xxxxxxxxxxx



Error:

Can anyone please tell me how to connect to such databases?

Hi shruti,

There seems to be a bit of information concerning the Oracle thin JDBC driver and load balancing at OTN Discussion Forums : Thin Driver and Load Balancing .... Maybe that will help.

To determine if it is a driver issue, you might try downloading a trial of Actuate BIRT Report designer which includes the DataDirect Oracle driver which is supposed to support a load balanced oracle connection. Load Balancing
