Re^2: DBI connect to IPv6

[daphnaw]

I've upgraded the sqlplus libraries we have been using from 10.2.0.3 to 11.2 (oracle-instantclient11.2-basic-11.2.0.1.0-1.x86_64.zip & oracle-instantclient11.2-sqlplus-11.2.0.1.0-1.x86_64.zip), so, yes I'm aware only 11.2 supports IPv6.

Connecting directly to sqlplus does work:

sqlplus system/manager@"[2001:db8:c18:3:214:4fff:fef2:30c1]:1521/anadb
+"

Any other ideas?

Any other ideas?

1. Use TNSNAMES.ORA
2. Use TNSNAMES.ORA. Really. Don't hardcode database connections, use the standard configuration file TNSNAMES.ORA.
3. Configure the machine running perl to resolve some arbitary hostname to the desired IPv6 address, e.g. by editing /etc/hosts / %windir%\system32\drivers\etc\hosts or by adding an AAAA record to your local DNS server, and use that hostname instead of the IPv6 address.
4. Look at the DBD::Oracle documentation, especially "the usual suspects" README*.*, CHANGES, NOTES, TODO.
5. Look at the source of DBD::Oracle to find out how the connect parameters are handled. Especially trace the way of the host parameter, watch out for calls to routines that can't handle IPv6 addresses.
6. Write a patch for DBD::Oracle, including tests, and send it to the DBD::Oracle maintainer.

I was able to resolve the issue by re-compliling the following dependent modules :

Clone

Params-Util

SQL-Statement
