    Abstract: The present invention is related to a method for routing requests among a plurality of database servers. A device intermediary to a client and a plurality of database servers receives a request to access a database provided by the plurality of database servers. The plurality of database servers can include a first database server configured to process write requests and one or more second database servers configured to process read requests. The device determines that the request to access the database is a read request. The device identifies, responsive to determining that the request is a read request, one of the one or more second database servers to send the request instead of the first database server. The device then transmits the request to the identified second database server.

    Abstract: The present disclosure is directed to systems and methods for performing load balancing and message routing by a device intermediary to a plurality of short message peer to peer (SMPP) clients and a plurality of SMPP servers. The device can receive a request from an SMPP client to establish an SMPP session, replace a first sequence identifier in the request with a second sequence identifier generated by the device, and store a mapping of the second sequence identifier to the first sequence identifier. The device can select an SMPP server to forward the request with the second sequence identifier and receive a response from the SMPP server with the second sequence identifier. The device can identify, from the mapping, the first sequence identifier and the connection to the SMPP client using the second sequence identifier to forward the SMPP response with the first sequence identifier.

    Abstract: The present disclosure is directed towards systems and methods for monitoring application level flow for database applications served by a cluster of servers. An application flow monitor may receive and distribute write requests of a client to at least one master server and read requests of the client to one or more slave servers, based on load balancing or similar policies. The application flow monitor may receive responses from the recipient server and may aggregate the requests and responses into Internet Protocol Flow Information Export (IPFIX) messages that may describe the entire communication flow for the application. Accordingly, application flow statistics may be monitored, regardless of which server was involved in any particular request/response exchange, allowing scalability without impairment of administrative processes.

    Abstract: The present disclosure is directed towards systems and methods for application performance measurement. A device may receive a first document for transmission to a client, comprising instructions for the client to transmit a request for an embedded object. A flow monitor executed the device may generate a unique identification associated with the first document, the unique identification identifying a first access of the first document, and transmit the first document and unique identification to the client. The device may receive, from the client, a request for the embedded object comprising the unique identification, and transmit, to a server, the request for the embedded object at a transmit time. The device may receive, from the server, the embedded object at a receipt time, and may transmit a performance record comprising an identification of the object, the server, the transmit time, the receipt time, and the unique identification to a data collector.

    Abstract: Disclosed herein includes a system, a method, and a device for disabling services in a cluster. A master node of a plurality of nodes of a cluster can receive a disable instruction for a service of the cluster. The master node can transmit to the plurality of nodes a transition instruction to instruct the other nodes to stop accepting requests from one or more client devices for the service. The master node can receive, from each of the plurality of nodes, a client count value indicative of a number of current client connections from the one or more client devices to one or more respective nodes of the plurality of nodes. The master node can determine that the client count value is a zero value for each node of the plurality of nodes. The master node can transmit an out of service instruction to each node of the plurality of nodes to disable the service on the cluster.

    Abstract: The present invention is related to a method for load balancing and connection multiplexing structured query language (SQL) queries among a plurality of database servers. A device intermediary to a plurality of clients and a plurality of database servers receives an SQL query to access a database provided by the plurality of database servers from a client via a first connection established between the device and the client. The device identifies for the SQL query a policy for selecting among the plurality of servers. The policy includes an expression to identify predetermined data from content of the SQL query. The device may select a server from the plurality of servers based on applying the expression of the policy to content of the SQL query and forward the SQL query to the selected server via a second connection established between the device and the selected server.

    Abstract: Systems and methods of the present disclosure provide for caching, by a device intermediary to a client and a database, a result of a structured query language (SQL) query request. In some embodiments, the device intermediary to a plurality of clients and a database receives a SQL response from the database to a first SQL query request of a client of the plurality of clients. The device may maintain a cache of SQL responses from the database. The device may identify that the first SQL query request matches a rule of a policy for caching SQL responses from the database. The policy may include a cache action to take when the rule is matched. The device may perform, responsive to the policy, on the SQL response the cache action identified by the policy.
