Diagnostics database archiving guide

statistical information correctly. . These updated values from the meta table are used by the archiving mechanism to clean up the disk space.

However, calling VACUUM FULL operation is not suggested from the product binaries as it takes exclusive locks on the tables.Therefore, it is often observed that in a heavily accessed system, the disk size eventually grows as archiving is not able to fetch the updated data related to pages and rows in the absence of VACUUM FULL operation.

Configurable parameters of DBConfig.xml

The DBConfig.xml is configuration file for databases used by SysFaultMgmt. This file contains the parameters for configurations of both LOGDB and evweb DB. These configurations together will decide when the archival activity should be triggered. The administrator can modify this file but should not modify any of the XML tags. The administrator should modify only the values of the tags as and when required.

Note: the page size for all databases mentioned here is 8 kB.

The in-depth explanation of each of the fields can be found below:

1.MaxNumPagesAllowed (LOGDB) - Argument is NUMBER OF PAGES: It indicates the maximum number of pages that the current database can hold.

2.DBRecordLifeTime (LOGDB) - Argument is NUMBER OF DAYS: As the max threshold time is 7 days, 10 days would be sufficient for this parameter. If any of the conditions hit, then the records will be moved to Archive DB.

3.ArchedRecordLifetime (LOGARCHDB) - Argument is NUMBER OF DAYS: It includes number of days, which is spent in CURRENT DB also. It will be desirable to have records of one year.

4.ArchDBSize (LOGARCHDB) - Argument is NUMBER OF PAGES: A value of 340 would be sufficient for this parameter.

Following are the Archival parameters for evweb & evweb_history:

5.MaxNumPagesAllowed (evweb DB) - Argument is NUMBER OF PAGES: It indicates the maximum number of pages that the current database size can grow before history management can move the events to history

UX 11i WBEM Software specifications

HP-UX 11i WBEM Software is a powerful tool designed to improve systems management in enterprise environments by utilizing the Web-Based Enterprise Management (WBEM) standard. This software is part of the HP-UX operating system, which is HP's proprietary Unix variant, and it offers a robust set of features designed to enhance the performance, reliability, and security of enterprise systems.

One of the main features of HP-UX 11i WBEM Software is its ability to provide a standardized interface for system management. WBEM is a protocol that allows for the management of networked hardware and software components in a consistent, interoperable manner. This feature is particularly beneficial for organizations that rely on a diverse range of hardware and applications, as it simplifies the integration of various system management tools into a unified framework.

Another important characteristic is the software’s support for CIM (Common Information Model). CIM is a standard designed to facilitate information exchange about the management of systems, networks, and services. HP-UX 11i WBEM Software uses CIM to enable administrators to gain a comprehensive view of their IT infrastructure, facilitating better decision-making and more effective resource management.

The adaptability of HP-UX 11i WBEM Software is noteworthy. It is designed to be extensible, allowing developers to create custom extensions and models that cater to specific business needs. This extensibility ensures that organizations can tailor the software to their unique environments, optimizing performance and enhancing operational efficiency.

Security is also a critical focus of HP-UX 11i WBEM Software. The architecture includes strong authentication mechanisms and access controls to safeguard sensitive data and management operations. This focus on security helps organizations maintain compliance with industry regulations and protects against unauthorized access.

Integration with existing management tools is another significant advantage. HP-UX 11i WBEM Software can be used alongside other system management solutions and protocols, allowing for seamless interoperability in diverse IT environments. This characteristic encourages organizations to leverage their current investments in management solutions while enhancing their capabilities through the use of WBEM.

In summary, HP-UX 11i WBEM Software is an integral part of HP's commitment to providing innovative solutions for enterprise systems management. Its standardized management interface, CIM support, extensibility, robust security features, and integration capabilities make it a valuable asset for organizations aiming to streamline their IT operations and improve overall system performance.
