DigiCert has announced that it will stop trusting G1 root certificates, effective April 15, 2026. This change impacts Oracle Integration customers using Oracle Autonomous Database (ATP / ADW), Oracle Advanced Queuing (AQ/ AQ JMS), Oracle DB, and Oracle DBaaS connections configured with wallet-based mutual TLS (mTLS) authentication. See DigiCert Announcement.
mTLS wallets generated for Oracle Autonomous Transaction Processing (ATP), Oracle Autonomous Data Warehouse (ADW), and related services up until January 28, 2026 used DigiCert G1 root certificates. As a result, wallets generated before January 28, 2026 will stop working after April 15, 2026. See Important Announcement for Autonomous AI Database Customers.
Who needs to take action?
This applies to Oracle Integration customers who are using wallet-based mutual TLS (mTLS) authentication with wallets generated before January 28, 2026 for the following adapters:
- Oracle ATP and ADW Adapters
- Oracle AQ / AQ JMS Adapters configured with ATP / ADW
- Oracle DB / DBaaS Adapters connecting to ATP / ADW using database wallets
Impact
Connections configured using mTLS wallets generated before January 28, 2026 will fail after April 15, 2026.
This may result in loss of connectivity between Oracle Integration and ATP, ADW, or AQ services until updated wallets are configured in your connections.
Required action
To avoid any disruption, complete the following steps before April 14, 2026:
- Re-download the wallet zip file from your ATP or ADW database instances.
- Update your Oracle ATP, ADW, AQ, AQ JMS, DB, and DBaaS adapter connections (which use ATP or ADW wallets) in Oracle Integration to use the newly downloaded wallet.
- Retest your connections and activate your integrations.
- Ensure all affected connections are updated on or before April 14, 2026.
