Best practices to handle AWS DMS tasks during PostgreSQL upgrades

The AWS Database Migration Service (AWS DMS) provides a managed solution for migrating and replicating databases to AWS, supporting both homogeneous and heterogeneous migrations. It allows seamless data migration from PostgreSQL databases to any supported target and vice versa. Open-source PostgreSQL regularly releases new versions, and Amazon RDS aims to support these within five months. Upgrading PostgreSQL instances is essential for security and compliance. Minor version upgrades focus on security and bug fixes without adding new functionalities, while major upgrades can change system tables and data formats. AWS DMS tasks require careful management during PostgreSQL upgrades. For minor upgrades, ongoing DMS tasks should be stopped and then resumed post-upgrade. For major upgrades, replication slots must be dropped before the upgrade, which will invalidate ongoing DMS tasks. After the upgrade, a new CDC-only task should be created to resume data migration. Minor version upgrades of the target PostgreSQL database do not affect AWS DMS CDC tasks, but major upgrades require stopping the DMS task, performing the upgrade, and ensuring compatibility with the replication instance before resuming the task.

Data Doctors: What’s behind Windows blue screen errors

The blue screen of death (BSOD) indicates a critical system issue in Windows. Common causes include: - Faulty or outdated drivers, often related to hardware changes. - Hardware problems, such as failures in RAM, hard drives, or motherboards. - Overheating due to dust, poor ventilation, or malfunctioning fans. - Corrupt system files from improper shutdowns, power surges, or software bugs. - Software conflicts, particularly with incompatible applications. - Issues from problematic Windows updates. - Viruses or malware that corrupt system files or disrupt functionality. - BIOS or firmware issues that introduce instability. - Defective external devices like USB sticks or hard drives. Resolving BSOD issues requires a systematic approach and understanding of error codes.

It must be a day with a ‘y’ in it – there’s a problematic Windows 11 update causing blue screens

Microsoft is addressing issues stemming from the KB5055523 update for Windows 11, which has caused Blue Screen of Death (BSoD) errors with the 0x18B error code. This update was automatically installed on most devices and is linked to the earlier KB5053656 preview update. Microsoft is implementing a Known Issue Rollback (KIR) to mitigate the problem, although it may take up to 24 hours for the fix to propagate to consumer and non-managed business devices. For enterprise-managed devices, IT administrators must manually resolve the issue by configuring the necessary Group Policy.

Microsoft Has a Fix for Windows’ Latest Blue Screen Problem

Unexpected crashes on Windows 11 version 24H2 have been reported, resulting in a secure kernel fatal error with the blue screen exception error code 0x18B. Microsoft has introduced a Known Issue Rollback (KIR) to address this issue by rolling back specific updates. For personal or non-managed computers, the fix will be automatically deployed via Windows Update, and users are advised to restart their PCs. For enterprise devices, IT departments must install the KIR Group Policy, found under Computer Configuration > Administrative Templates, and a restart of affected devices is required. The blue screen bug appeared after a Patch Tuesday update that addressed 134 security vulnerabilities, including a zero-day flaw.

Windows Server 2025 may lose DC connectivity after restart

Microsoft has warned about potential accessibility issues with Windows Server 2025 domain controllers after a restart, where affected servers revert to the default firewall profile, disrupting applications and services. A temporary workaround involves manually restarting the network adapter on the impacted servers using the PowerShell command: Restart-NetAdapter *. This workaround needs to be reapplied after each restart of the domain controller, and Microsoft recommends setting up a scheduled task to automate this process. Windows Server 2025, launched earlier this year, introduced new features and security enhancements but has faced previous issues, including freezing Remote Desktop sessions and accidental upgrades from Windows Server 2022. Developers are currently working on a permanent solution for the domain controller issue.

Windows Server 2025 Restart Bug Breaks Connection with Active Directory Domain Controller

Microsoft has warned IT administrators about a significant issue affecting Windows Server 2025 domain controllers, which may struggle to manage network traffic after a system restart. This problem arises because the domain controllers revert to the standard firewall profile instead of the required domain firewall profile, leading to potential inaccessibility on the domain network, application failures, and open ports that could pose security risks. The issue specifically affects Windows Server 2025 systems with the Active Directory Domain Services role, while client systems and earlier server versions remain unaffected. To address this, Microsoft recommends a temporary workaround: manually restarting the network adapter using PowerShell with the command Restart-NetAdapter * after each reboot. Administrators are advised to create a scheduled task for automation, monitor domain controllers for disruptions, and minimize unnecessary restarts. Microsoft is working on a permanent fix, with an update expected in the future.

Microsoft: Windows Server 2025 restarts break connectivity on some DCs

Microsoft has warned IT administrators about a potential issue with Windows Server 2025 domain controllers (DCs) becoming inaccessible after a restart, due to defaulting to the standard firewall profile instead of domain-specific settings. This mismanagement can lead to DCs being unreachable on the domain network or improperly accessible through restricted ports and protocols. A workaround involves manually restarting the network adapter on affected servers after each reboot, and Microsoft recommends setting up a scheduled task for this. The company is working on a permanent solution for a future update. Additionally, Microsoft has alerted users to another issue with Windows Hello logins related to the KB5055523 April 2025 security update and has implemented a fix for authentication issues with Credential Guard and the Kerberos PKINIT pre-auth security protocol.
