Proper care of SUN/ORACLE servers is important to keep them secure, functional and long-lasting. An effective maintenance plan can minimize system outages, boost operational productivity and protect information. Please see the overall list below for completing SUN/ORACLE server maintenance. 

 

Consistent System Auditing 

• Periodic System auditing of your SUN/ORACLE servers system health is important to accomplish in order to avoid any catastrophic failures. Some of the important steps include: 
• Real-time monitoring using Oracle Enterprise Manager (OEM). 
• Tracking the extent of utilization of CPU, memory, and disk resources.
• Systematically scanning error messages in the system logs (var/adm/messages dmesg syslog). 
• Tracking the processes that are actively running with tools like prstat. 

 

Software & Firmware Revisions

• These steps greatly mitigate the security risks or system malfunctioning. Always include the following steps while revising your business strategy: 
• Patching a defect by applying Oracle Solaris OS updates. 
• Patched firmware and new enhanced drivers deployed to improve the systems where new features are delivered. 
• Patch Maintenance using the Oracle OPatch utility. 
• Applying Oracle Recommended Patches periodically. 

 

Backup & Disaster Recovery Planning

 

• This, along with preventative measures, helps ensure the protection from system failure. Always follow these tips: 
• Regularly scheduled back-up maintenance with tools such as Oracle RMAN or ZFS snapshots. 
• Backup tree restoration drills to validate the integrity of the backups. 
• Backup contents stored in different media such as offsite or cloud storage. 
• Write down a document outlining the strategies for attaining goals in case of a disaster (DR) and conduct frequent examinations.

 

Storage and Disk Optimization 

• Effective storage management facilitates the avoidance of disk failures as well as data losses.  
• Monitor ZFS pool health with ‘zpool status’.  
• Keep tracking RAID structures for redundancy.  
• Resolve performance bottlenecks by freeing up disk space.  
• Swap failing disks before they result in system downtime. 

 

Security and Cyber Access

• Taking steps to maintain system security is one way in which one can thwart malicious attempts and unauthorized access.   
• Establish role based access control (RBAC).  
• Restrict access by securing SSH configurations (/etc/ssh/sshd_config).  
• Revise security policies periodically and enable firewall rules.  
• Establish Multi-factor authentication (MFA) for critical systems.  

 

Network and Connectivity Administration 

• To ensure strong and uninterrupted network performance without any connectivity issues, there is a need to prevent any possible downtime.  
• Monitor the network interfaces with dladm show-link command.  
• Network redundancy can be achieved using IPMP (IP Multipathing) mode.   
• Use netstat and ping tools to analyze latency and bandwidth.  
• Have an up to date network topology map for easy troubleshooting.  

 

Performance Maximization 

• To ensure efficient workload management, server performance should be optimized.  
• Monitor resource usage with prstat and vmstat commands.  
• Set kernel variables to achieve the desired efficiency.  
• Use AWR (Automatic Workload Repository) for Tuning Oracle Database performance.  
• Optimize application workload distribution across the system to manage resources effectively.  

 

Maintenance of Hardware and Other Components  

• When properly maintained, SUN/ORACLE servers can have an extended lifespan.
• Check that the power supplies and cooling fans are operating properly to avert overheating.  
• Replace malfunctioning hardware components when applicable.  
• Verify correct hardware functioning by running the computer’s Power-On Self-Test (POST) diagnostics.  
• Ensure that dust and other pollutants do not accumulate around the server components critical for its operation.  

 

Log Management & Troubleshooting  

• Efficiently managed logs can be useful in enhancing problem diagnosis and resolution time.  
• Perform periodic examination of system logs (/var/adm/messages, dmesg, syslog).  
• For detailed diagnosis, use the Oracle Explorer Data Collector.  
• Use Oracle ILOM logs to diagnose hardware components problems.  
• Program alerts to go off for vital errors and failures.  

 

Support & Documentation  

• Proper support with corresponding documentation greatly reduces the time of issue resolution.  
• Have accurate documents covering the server configuration, servers’ patches, and updates.  
• Get Oracle Premier Support to be provided within the organization for patches and help.  
• Access the MOS to guides for troubleshooting and get system updates.  
• Create a Guide Designed for Intended Use for the internal staff to collect information for ease in their future reference.
