HADR and Type 4 Driver

[Mark A]

Does anyone have some java code for automatic client reroute using the Type
4 client with HADR? The Type 2 client supports this automatically with parms
in the database configuration, but it has to be done in the code for the
type 4 driver.

Mark,

DB2 UDB's V8.2 automatic client reroute is supported for both type-2 and
type-4 drivers. See

There are some slight differences, but it basically works the same way.

Thanks Larry. Seems like the HADR/TSA No Shared Disk on Linux document might
need to be clarified a bit to point to the documentation. Here is what it
says:

"If using jcc type 4 clients, client reroute information will not be picked
up from the local db directory; applications need to be designed to store
and recover the alternate server information in a text file."

That is one of the "slight differences" :-).
