Systems and methods for allocating computing resources for a multi-tiered application are disclosed. A computer-implemented method includes: determining, by a computing device, a topology of a multi-tiered application; determining, by the computing device, a modeled setting of a computing resource for the multi-tiered application based on the determined topology; determining, by the computing device, an actual usage of the computing resource by the multi-tiered application; and adjusting, by the computing device, an allocation of the computing resource to the multi-tiered application based on the actual usage and the modeled setting.

Assessment and dynamic provisioning of computing resources for multi-tiered application

The invention is an improved integrated development environment (IDE). In particular, the improved IDE comprises a text editor, a source code analyzer, a rule database, and a solution database. The rule database stores source code patterns that represent classes of bugs, while the solution database stores source code patterns that represent corresponding alternative source code that corrects the bugs. The source code analyzer dynamically evaluates source code as a programmer develops the source code in the text editor, periodically comparing source code with the patterns in the rule database. If the source code analyzer matches a pattern with any source code, the source code analyzer displays the corresponding source code pattern from the solution database. The source code analyzer further gives the programmer the option to select the source code pattern from the solution database, at which time the editor changes the source code to conform to the appropriate pattern.

A log manager for tracing a user or process in a data processing system is provided. A user inputs various criteria in the log manager, indicating exactly what is to be traced. A tracer key is created based on this information. The tracer key is then transmitted to the appropriate applications in the system, which then gather the relevant information. The applications then forward this information to a log receiver. The receiver stores the information. The log receiver can then produce a trace report for the user at any time the user wishes.

Efficient, centralized management of application log configuration settings

A hijack avoidance technique avoids presenting an access to more than one of a chain of authentication objects, such as a chain of Lightweight Directory Access Protocol (LDAP) authenticators. A pre-filter determines whether an authentication object should be presented with the access by comparing either all or a portion of a domain suffix, an IP address, or other identification other than the user ID with predetermined values. If the filter criterion is met, the associated authentication object accepts or rejects the access. Otherwise, the access is passed to the next authentication object in the chain. The first authentication object may be associated with a hosting entity and successive authentication objects each associated with different customers of the hosting entity. By virtue of the filtering, each authentication object is presented only with a particular subset of all of the possible access identifiers, which avoids presenting all of the previously unauthenticated accesses to each authentication object in the chain.

Pass-through hijack avoidance technique for cascaded authentication

A tracer object for tracing a user or process in a data processing system is provided. An application receives a tracer key containing a request for information to be traced. The received tracer key is checked against all tracer keys that the application has stored. If a match between two tracer keys is found, the stored tracer key maps the tracer key containing the request to the stored tracer key's associated tracer object and applies the conditions and modifiers contained in the tracer key containing the request to the tracer object. The tracer object then gathers the required information as requested.

User/process runtime system trace

An automated method for creating only the necessary joins in a SQL query. The present invention comprises a Query Program (QP), a Query Generation Program (QGP), and a Clause Generation Program (CGP). The QP accepts the query fields, filters, and sort criteria from the user, generates the query, sends the query to the database, and displays the query results. The QGP creates the query clause strings and inserts the strings into the SQL template. The QGP generates the SELECT, (filter) WHERE, and ORDER BY clauses. The QGP analyzes each parameter in a parameter list to determine if the parameter is on the added aliases list. If the parameter is not on the added aliases list, the QGP runs the CGP for the parameter. The CGP generates the FROM, JOIN, and (join) WHERE clauses and adds the clauses to the appropriate clause strings.

Method and system for generating SQL joins to optimize performance

A method for implementing a front-end user sort request includes receiving a list request, decomposing the list request and creating a sort entry object using a list of column values initially retrieved from a data storage medium. A sort routine is performed on at least a first column of the list of column values in the sort entry object, wherein a compare function of the sort routine is dependent upon information obtained from decomposing the list request. The list request is rebuilt in accordance with the completion of the sort routine.

Multi-column multi-data type internationalized sort extension for web applications

A method for implementing a web-based, front-end user request includes receiving a list request from a front-end user, and receiving user characteristics associated with the list request. Data corresponding to the list request is retrieved from a data storage medium, and the retrieved data is configured in accordance with the user characteristics. The configured data is returned to the front-end user in accordance with the user characteristics.

Multi-column multi-data type internationalized sort extension method for web applications

The present invention provides a method, computer program product, and a data processing system for validating and configuring a database transaction request. A first transaction criteria of a plurality of transaction criteria is identified in a singleton in-memory object by reading a client identifier element value specified in a database transaction request. Each of the plurality of transaction criteria is associated with a respective client. Default data for a database path is determined based on the client identifier element value. A database command is generated that includes the default data.

Method and apparatus for validating and configuring database transaction requests from multiple clients

A method in a data processing system for generating return data responsive to a database request is provided. A response from a data store is detected. A merge reference section in a singleton in-memory object is located. A merge reference of the merge reference section is identified. A reference column from the merge reference is determined and data is merged with the reference column to form a merged value according to an order. The merged value is then placed in the response.

Method and apparatus for splitting and merging request and response data at runtime

A method, apparatus, and computer instructions of generating SQL statements at run time from generic and abstract XML request and response messages is provided. A set of generic and abstract XML schemas are provided for a client to send request XML messages for performing actions on information of objects in a data store. An adaptor processes the request XML messages and generates the SQL statements to submit to the data store. Upon receiving results, the adaptor sends response XML messages that adhere to the generic and abstract XML schemas to the client, which then obtains values of results from response XML message.
