Bug#1016992: libdbd-oracle-perl: Built against unsupported Oracle Instant Client 12.1

[Alex Muntada]

Hi Daniel,

> libdbd-oracle-perl has been built against OIC 12.1
> since version 1.66-1 (Aug 30, 2013).
> 
> Oracle's "Release Schedule of Current Database Releases":
>   https://support.oracle.com/knowledge/Oracle%20Database%20Products/742060_1.html
> says "Patching End Dates" are:
>   * 12.1 - Jul 31, 2022
>   * 19c  - Apr 30, 2024
>   * 21c  - Apr 30, 2024

Thanks for sharing that URL above. After reading it, let me
expand on the support details for the record of this bug:

* 12.1.0.2 (Terminal Release) "Patching End Dates":
  - Jul 31, 2022 with paid ES, ULA, or EBS waiver
  - Dec 31, 2023 (with a Custom Market Driven Support Contract)
* 19c (Long Term Release)
  - April 30, 2025 with no ES/ULA
    (see that you wrote **2024** here!)
  - April 30, 2027 with ES/ULA
* 21c (Innovation Release)
  - April 30, 2024

> Upstream DBD::Oracle 1.81 introduced support for OIC 21.
> 
> Could the following two changes be made?
>   1) Import upstream version 1.83
>   2) Build against OIC 19c (Version 19.16) or 21c (Version 21.7)
>
> However, two problems remain:
>   1) Bookworm will be supported well beyond Apr 30, 2024
>   2) Oracle may release higher 19.xx and 21.x versions

Seeing the above end dates, my bet is on 19c right now for two
reasons: 1) is the longest supported version right now, and 2)
is a Long Term Release, which means that they may extend its
support longer as they did with 12.1.

Cheers,
Alex
