Re: dataguard connection question

Thanks Dick,
Do you mean the second host to xythdb-02? How about SERVICE_NAME? is always XYTHT1? 

Thanks, --joan

 jdbc:oracle:thin:@(DESCRIPTION=(

 ADDRESS=(PROTOCOL=tcp)(HOST=test-xythdb-01.uit.tufts.edu)(PORT=11003)
> address=(protocol=tcp)(host=test-xythdb-02.uit.tuft.sedu)  PORT=11003)) ?

Joan,

        Your biggest difficulty here is JDBC because it does not use the
Oracle SQL*Net layer thereby making this a touch difficult.   The
following is something I pulled (in spirit only) from another project I
worked on that had a requirement for a standby database & no manual
intervention on the app side:

jdbc:oracle:thin:@(DESCRIPTION=(
ADDRESS=(PROTOCOL=tcp)(HOST=test-xythdb-01.uit.tufts.edu)(PORT=11003) address=(protocol=tcp)(host=test-xythdb-01.uit.tufts.edu)(PORT=11003)) 
     (CONNECT_DATA=(SERVICE_NAME=XYTHT1))) JDBCConnectionPool:395

It helped in that setup and did work flawlessly, but yours may be
different.  Alternatively you might consider setting up a connection
manager somewhere in your infrastructure.  It can handle just this type
of problem, but it's another layer of indirection.

Subject: dataguard connection question

Hi List,

I have question regarding dataguard, the primary database is xytht1, the

standby is xytht2. the oracle is 11.1.0.7. Our client is using jdbc thin

client to connect the primary database. the connection string is

jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=test-xythdb-
01.uit.tufts.edu)(PORT=11003))(CONNECT_DATA=(SERVICE_NAME=XYTHT1))) JDBCConnectionPool:395
After I tested switchover, the client lost connection, and have to manually reconfigure to change the HOST and service name. This is not acceptable to our client. I have no knowledge on how to automatically switchover/failover for the client jdbc connection. Do you have any ideas on this? Thank you for any helps. 

Joan
