Frequently Asked Questions

What is hosting?

Frequently Asked Questions
Once you have a website and a domain name you will then need to make it accessible to the internet. This can be achieved by housing your site on a computer that is permanently connected to the internet (a server). Using a hosting service lets many users share the cost of a fast Internet connection for serving websites on a machine that has been optimized solely for the purpose. The prices of hosting vary tremendously as does the service provided.

What applications can be clustered?

Almost all "server-based" applications that allows users to connect via an IP address can be clustered. Successful examples include Apache, Samba, Mysql, and PostgresQL. Other uses might include mail servers or NFS servers. For best results the applications that are clustered should support client connectivity via TCP connections. This protocol is more reliable and will are more likely to handle network fail-overs or even fail-overs of the application to the other host, in a more robust manner.

What if I have clustered servers?

SQL Backup - Frequently asked questions
SQL Backup Pro contains a cluster-aware installation mechanism that will automatically detect cluster installations while installing SQL Backup. You can also do this by running SQBServerSetup.exe on one node and installing SQL Backup manually. Alternatively, this can also be done via the Install/Upgrade menu in the GUI. SQL Backup can then be activated by running LicenseActivation.exe on any node in the clusters.

What are Clustered Indexes?

SELECTservices | 9017 - Using Clustered Indexes
A Clustered Index is an index on a table or view that reorganizes the physical data of a table or view into sequentially ordered rows. The danger with using Clustered Indexes is that since the data is sequentially ordered, inserts into the table will take a slight performance hit due to the reordering of the data.

Can GNU/Linux machines be clustered?

The linux-kernel mailing list FAQ
REG) Different people mean different things when they talk about clustering. Some people want transparent fault tolerance and load balancing of general applications, others want parallel processing of a single job. Most people who talk about fault tolerance expect hardware and OS support of this (if a node goes down, the OS will automatically migrate the application to another node). This is not (yet) available for Linux.

Can I deploy a Mainsoft application on a clustered environment?

Frequently asked Questions about Mainsoft for Java EE
Yes. Applications developed with the Enterprise or Portal Editions can be deployed in a clustered environment. If you are using Grasshopper, you can deploy to Tomcat only in a single CPU, non-clustered server. The Mainsoft for Java EE runtime libraries consist of JAR files that are compliant with the Java specification. These files can either be added to the classpath of the Java EE application server, or they can be included in the WAR file of the application being deployed.

Are expatriates clustered in certain areas?

For those with families, particularly if they attend the American School, SIS or some other foreign schools, then the Pudong New Area and Hongqiao Area are popular, where most of the villa properties are located.

How do you implement Clustered Indexes?

Please Note: For issues setting up Clustered Indexes, please consult your internal Database Administrator. The following information is for background and reference purposes.

What is the basic difference between clustered and a non-clustered index?

Frequently Asked Questions about MS-SQl server
The difference is that, Clustered index is unique for any given table and we can have only one clustered index on a table. The leaf level of a clustered index is the actual data and the data is resorted in case of clustered index. Whereas in case of non-clustered index the leaf level is actually a pointer to the data in rows so we can have as many non-clustered indexes as we can on the db.

Is it required that I take all of the classes that are clustered in my LC?

FAQ
Yes. Students must take all courses that are offered with their community. The only exception is for those courses in which a student has AP or SEOP credit.

What is the difference between Clustered Tables and Pooled Tables?

SAP ABAP interview questions
Ans A pooled table is used to combine several logical tables in the ABAP/4 dictionary. Pooled tables are logical tables that must be assigned to a table pool when they are defined. Cluster table are logical tables that must be assigned to a table cluster when they are defined. Cluster table can be used to store control data. They can also used to store temporary data or text such as documentation.
