Want to set up server side TAF. Not a whhole lot of documentation out thre that is very specific. created a service and added TAf entries to it.

/home/oracle> srvctl modify service -d CDRTST -s POSTST -m basic -e select

checking the service shows:

/home/oracle> srvctl config service -d CDRTST -s POSTST
Service name: POSTST
Service is enabled
Server pool: CDRTST_POSTST
Cardinality: 2
Disconnect: false
Service role: PRIMARY
Management policy: AUTOMATIC
DTP transaction: false
AQ HA notifications: false
Failover type: SELECT
Failover method: BASIC
TAF failover retries: 0
TAF failover delay: 0
Connection Load Balancing Goal: LONG
Runtime Load Balancing Goal: NONE
TAF policy specification: NONE
Preferred instances: CDRTST1,CDRTST2
Available instances:

Yet when I test the failover, I get:

SQL> select * from v$instance;
select * from v$instance
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Process ID: 27737
Session ID: 4 Serial number: 19

SQL> select * from v$instance;
ORA-03114: not connected to ORACLE


Client side setup works perfectly....but just CANNOT seem to get server side setup and working....

Any suggestions?

What is the connect string you are using?

sqlplus system/password@MYTEST.BTRUCK.COM

LDAP resolves that to scan_listener, and service_name for the service.
Can;t get copy/paste to work here and do not wish to type the whole string....

connection to service works fine, and I am able to get the failover to work 1 time but subsequent connections will fail when instance is shut down under it instead of failing over to surviving instance.
