transaction application continuity

cptkirksh

I thought I might put this out here while I work through my little problem. I am trying to test TAC on an Oracle 19 2 node RAC. I have followed the steps from this link

https://www.oracle.com/technetwork/database/options/clustering/applicationcontinuity/applicationcontinuityformaa-6348196.pdf

Here is the config for the service for the TAC.

[[email protected] ~]$ srvctl config service pdb_tac database -db orcl

When I run the connection string like this it times out on the connection.

(DESCRIPTION = (CONNECT_TIMEOUT=120) (RETRY_COUNT=20)(RETRY_DELAY=3)(TRANSPORT_CONNECT_TIMEOUT=3)(ADDRESS_LIST =(LOAD_BALANCE=on)(ADDRESS = (PROTOCOL = TCP)(HOST=rac-scan)(PORT=1521))) (CONNECT_DATA=(SERVICE_NAME = pdb_tac.localdomain)))

if I remove the (CONNECT_TIMEOUT=120) (RETRY_COUNT=20)(RETRY_DELAY=3)(TRANSPORT_CONNECT_TIMEOUT=3) it will connect.

My question is why does that cause my connection to not connect? Thanks in advance
