FSE process clean-up may be noticed when working with FSE commands. After an FSE command completes its task, it returns control to the command prompt after a short delay. This is because the command, after termination, leaves its connection open until the omniORB thread terminates it. omniORB scans for idle connections at regular intervals. A shorter interval will result in a shorter delay after the FSE command termination.

To shorten this interval, add the following line to the file omniORB.cfg. This will set the scanning interval to 1 second:

scanGranularity = 1

If omniORB.cfg is not yet present in its directory, copy its template to this directory and add the above line to it.

Linux specific

omniORB.cfg is located in the directory /etc/opt/fse, and its template is located in the directory /opt/fse/newconfig.

Windows specific

omniORB.cfg is located in the directory %InstallPath%\etc. Its template can be found in the directory %InstallPath%\newconfig.

CAUTION: Note that the FSE host does not need to be restarted for changes in omniORB.cfg to take effect, and that its reconfiguration affects all local FSE processes, not only FSE commands.

If you configure the file omniORB.cfg only to shorten the termination delay for FSE commands as specified above, you need to consider that omniORB.cfg affects the configuration of the FSE interprocess communication. For more information, see the FSE User’s Guide, chapter ”Configuring FSE”, section ”Reconfiguring FSE interprocess communication”.

Preventing exhaustion of CORBA sockets

As described in section ”Shortening the termination delay for FSE commands” on page 15, CORBA technology and its omniORB implementation is used for internal interprocess communication in the FSE implementation. Each CORBA connection reserves one socket from a pool of available CORBA sockets. If there are too many concurrent FSE processes running in the FSE implementation, the pool of available CORBA sockets gets exhausted. This happens when numerous brief FSE operations, especially recalls of small files, are being triggered for a long period of time.

This problem generally occurs because each FSE process, after termination, leaves its connection open and the belonging CORBA socket in waiting state, until the omniORB thread terminates it. A solution to the problem is reconfiguration of omniORB so that it scans for idle connections and terminates them more frequently.

To prevent CORBA from exhausting all sockets, proceed as follows:

1.Shut down the FSE implementation: fse --stop

2.On the consolidated FSE system or FSE server, stop the omniORB/CORBA naming service: omniNames --stop

3.Remove temporary files created by omniNames: Linux specific

#rm -r /var/opt/fse/omniorb/*

Windows specific

%InstallPath%\var\omniorb>del *.*

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
