Summary
This PR adds configurable Oracle Thick mode support to the SecretsManagerRDSOracleRotationSingleUser template.
Changes
Oracle Thick Mode Toggle
Adds module-level initialization that checks the ORACLE_THICK_MODE environment variable. When enabled, calls oracledb.init_oracle_client() before any connection is created. This is required for customers whose Oracle databases enforce Native Network Encryption (NNE), checksumming, or Kerberos authentication, features that only work in python-oracledb's Thick mode.
New environment variables:
When enabled, Oracle Instant Client libraries must be available via LD_LIBRARY_PATH (e.g., via a Lambda Layer).
Backward compatible, default behavior (thin mode) is unchanged.
Testing
Tested against Oracle Database Free (26ai) running on EC2 with Native Network Encryption set to REQUIRED:
Note
The same change should be applied to SecretsManagerRDSOracleRotationMultiUser as well.
