Runtime connection load balancing of work across connections to a clustered computing system involves the routing of requests for a service, based on the current operational performance of each of the instances that offer the service. A connection is selected from an identified connection pool, to connect to an instance that provides the service for routing a work request. The operational performance of the instances may be represented by performance information that characterizes the response time and/or the throughput of the service that is provided by a particular instance on a respective node of the system, and is relative to other instances that offer the same service.

Techniques for fast recovery and/or balancing of connections to a clustered computing system provide management of such connections by determining a number of connections to load balance across nodes and by triggering creation of such connections. In one aspect, a notification of an event regarding the clustered computing system is received by a connection pool manager, a pool of connections to the system is identified based on the notification, and one or more connections from the pool are processed in response to the event. According to an embodiment, the notification comprises the identities of the service, database, server instance and machine that correspond to the event.

A system provides cloud-based identity and access management. The system receives a request from a client for an identity management service, authenticates the request, and accesses a microservice based on the request. The system determines, based on the request, a tenancy of the client, a tenancy of a user, and a tenancy of a resource. The system retrieves data from the determined tenancies as required to process the request, where the data is retrieved by the microservice using a connection pool that provides connections to the database. The system then performs the identity management service by the appropriate microservice responsible for processing the received request.

When an application server prepares the connection made to the database server, an identifier for definitely identifying the database server of connection destination is allotted to the connection. When a fault occurs in a database system, the database identifier of the connection is specified and only a connection allotted with the same identifier as the specified identification is discarded from a connection pool. When a request is received from a client computer, a connection is acquired from the connection pool. The acquired connection is decided as to whether to be faulty and if the acquired connection is determined as being faulty, a database server to be coupled to the faulty connection is specified by consulting connection management information. All connections made or coupled to the specified database server are discarded from the connection pool and a new connection is prepared.

An interface can serve as a client-mainframe interface, enabling clients to develop applications without a need to understand mainframe processes and screen flows. Extended Tool Command Language (Tcl) can define services that can include a series of interactions with a mainframe system and service definitions can be added or updated on the interface during operation of the interface without disrupting processing. The service definitions can enable the interface to receive XML requests from a client, parse the XML requests, execute the service scripts to interact with the mainframe systems, generate the result in a XML format and send the XML file back to the client. Fundamental Mainframe Interactions (FMI) commands can interact with the mainframe systems and enable the specification of the XML structure of the request and response. The interface can provide efficient connection pooling management and connection life cycle control to improve the performance of the mainframe system interactions.

Provided are systems and methods of auditing database end user activity. The methods include extending a web application in order to tie a user of the web application to the user's web application login operation where the web application is coupled to a web application server that employs a connection pool for accessing a database. Extending the web application is carried out without modifying the web applications code. Existing application programming interfaces may be leveraged in carrying out the audit of database end user activity. All user database activity is monitored and associated with an individual user's login operation and an audit trail of the user's activity within the database is created.

The invention provides a method and a system for multiplex and connection management of a load balancer. The method for multiplex and connection management of the load balancer comprises that the load balancer receives a user request from one application or a plurality of applications and puts the user request into a queue and records connection information of the user request; a connection manager makes sure whether a free connection exists in a connection pool or in a plurality of connection pool, wherein the connection pools are provided with a maximum number of connections and a minimum number of connections; if no free connection exists, the connection manager creates a new connection and allocates the newly-created connection to the load balancer, and if a free connection exists, the connection manager allocates the free connection to the load balancer. The load balancer transmits the user requests to a corresponding server through the allocated connection and forwards response data from the corresponding server to a user.

The invention discloses a multiplexing method based on transmission control protocol (TCP) connection. The method is implemented by multiplexing a channel between a proxy server and a server through a plurality of clients. A Client tries to communicate with the server, a SOCKET connecting request is required to be established between the Client and the proxy server, a TCP connection pool management program is installed in the proxy server, a unique ID is distributed to the Client after the connection request is legal, the ID and the SOCKET are used as a key value pair and stored in a forwarding table, the communication request of the Client is agreed, the distributed ID is carried back, and equivalently, a virtual channel for bidirectional communication is established between the Client and the Server. By the method, the frequency of creating and destroying the SOCKET in the server is reduced, and the resources of the server are saved. Meanwhile, multiplexing is realized by establishing the virtual channel between the server and numerous clients.

The method further includes, in response to the number of the metablock update candidates satisfying the relinking pool threshold, updating the linking of the blocks of the metablock update candidates to form updated metablocks.

The invention provides a control method of a database connection pool. The control method includes: normalizing thread priority; judging whether the current connection pool is empty or not, if not, taking out first data connection, setting the current state to be busy, and returning to the data connection; if yes, judging whether number of unreturned data connection in a current external program reaches maximum number of connection in the connection pool or not, if not, increasing the data connection prior to adding the same to the current database connection pool, and returning to the first data connection of the database connection pool; if the number of the unreturned data connection used in the current external program reaches the maximum number of the connection, setting the priority of the current thread, acquiring first time as current time, circularly judging whether the current connection pool is empty or not, and allowing the database connection pool to enter a waiting state. Data access performance can be effectively improved under the condition of high concurrency and multi-data source environment.
