Diagnostics database archiving guide

All the events that qualifies the age limits in the configuration are moved from current DB to archive DB. All the events in archive DB that qualifies the age limit gets purged from archive database.

Space policy

The space policy triggers when the actual size of the db (in pages) exceeds the configured size. When actual size of archive DB exceeds the configured size, it gets pruned.

NOTE:

The diagnostics products with Postgres 8.4.8 are fine tuned to call the autovacuum on each of the databases. The autovacuum daemon is tuned to run after every 30 minutes to ensure all the dead pages and tuples are flushed and space is made available. The vacuum operation can also be initiated by restarting the Postgres services.

What happens on archiving?

In case of LOGDB,

1.The events from tables namely rawlog/rawlogdetails are moved to the corresponding tables of the LOGARCHDB if the size of the current DB exceeds the configured size

2.Also the LOGARCHDB is checked for the pages it occupies on the disk. If the pages exceeds configured limits, events are pruned from the LOGARCHDB.

In case of evweb db,

1.The events from tables namely evt_summary_t, evt_prop_t etc. tables are moved to the corresponding tables of the evweb_history db.

2.The evweb_history DB is then checked for the space condition. If the number of pages occupied by the evweb_history DB exceeds configured limits then archiving deletes certain events from the evweb_history DB.

How to trigger Archiving in the Product

To Trigger Archiving in SysFaultMgmt

In SysFaultMgmt, the archiving is triggered periodically by means of the archiving job.

Archiving in evweb/evweb_history database

The archiving in evweb/evweb_history database can be triggered by starting the products by using the following command:

cimprovider -dm SFMProviderModule

(disabling the SFM)

cimprovider -em SFMProviderModule

(enabling the SFM)

 

OR

 

cimserver –s

(stopping the cimserver)

 

cimserver

(starting the cimserver)

 

Once the product is restarted, the job responsible for triggering the archiving in evweb/evweb_history, registers itself as repetitive job, as soon as the first event is inserted in the database. Thereafter, the archiving job is called every 6 hours to check the need of archiving on the evweb/evweb_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.
