I would like to use complex connect strings similar to JDBC thin driver, e.g.
(DESCRIPTION=(CONNECTTIMEOUT=5)(TRANSPORTCONNECTTIMEOUT=3)(RETRYCOUNT=5)
(ADDRESSLIST=(LOADBALANCE=OFF)(FAILOVER=ON)
(ADDRESS=(PROTOCOL=tcp)(HOST=xyz1.abc.def.loc)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=xyz2.abc.def.loc)(PORT=1521)))
(CONNECTDATA=(SERVICENAME=ABCD_GCSTANDBY)))

It is similar to the entries you can put into the TNSNAMES.ORA file.

It looks like ODAC.net does support something similar,
I would like to have it in the VCL version.

To us, the most important thing is Connect Time Failover
