UTL_HTTP Fails with "ORA-44102: Unknown or Unsupported Algorithm" After Upgrading Database to 12.1.0.2 (Doc ID 2472051.1)

Last updated on FEBRUARY 19, 2019

Applies to:

PL/SQL - Version 12.1.0.2 to 12.1.0.2 [Release 12.1]
Information in this document applies to any platform.

Symptoms

The call to a remote web service using UTL_HTTP fails with "ORA-44102: Unknown or Unsupported Algorithm" after upgrading the database from 11.2.0.4 to 12.1.0.2. The same call works fine when invoked from 11.2.0.4 database.

As can be seen above, the response contains an empty "Content-Encoding" header, which is illegal as per the HTTP specification documented at the following URL

https://tools.ietf.org/html/rfc2616#section-14.11

Changes

The invocation of the web service is successful in RDBMS version 11.2.0.4 and other 12c versions as well e.g. 12.1.0.1, 12.2.0.1 and onwards. The UTL_HTTP package fails with "ORA-44102" only in version 12.1.0.2.
