Techniques for updating an application using a non-servicing state are disclosed. One or more embodiments include executing an application, in a state which does not provide services, to avoid the application being restarted by a watchdog process. The non-servicing state may not perform any function other than to continue executing at least one proxy service process which avoids the application being restarted by a watchdog process. Responsive to determining that the application process is executing, the watchdog process does not detect any issue with the application, and therefore does not restart the application. The watchdog process may verify the continuing execution of the application process by, for example, determining that the application process is included in a list of executing processes managed by an operating system. The watchdog process may verify the continuing execution of the application process by, for example, communicating with the application process.

Application modification with proxy service process

A system includes a transmitting agent configured to select a transport mechanism for transmitting a data item, and a receiving agent configured to select one or more data repositories and a storage process for storing the data item. One storage process includes storing the data item temporarily in the second data repository, and subsequently transferring the data item from the second data repository into the first data repository. Another storage process includes storing the data item into a first data repository without temporarily storing the data item in the second data repository.

Method and system for selecting a transport mechanism and a storage process

A method includes extending an interface, to a device outside a firewall, for requesting a service performed by a device inside the firewall. The interface is extended using a software component, executing outside the firewall, which executes a separate interface to accept requests for services from devices outside the firewall. The separate interface, exposed outside the firewall, is configured for accepting a subset of the services available inside the firewall.

Exposing an interface to devices outside a network for requesting a subset of services provided by devices inside the network

A system of remote nodes may be divided into sets of partner nodes. One remote node becomes a partner of another remote node. As partners, the nodes agree to monitor each other's health and report anomalies, such as a failure of one of the nodes, to a monitoring server. The nodes do so using a persistent communication link, such as an open socket. Using the described techniques, the monitoring load of a system is distributed in part away from the monitoring server and to the nodes themselves. This may reduce the resources required of the monitoring server. At the same time, since nodes are now being monitored by partner nodes that are likely to be closer than the monitoring server, and/or on account of the monitoring being performed via a persistent communication link, certain failures can be detected in real-time or near real-time.

Detect process health remotely in a realtime fashion

A method for generating instructions for a monitoring facility. The method includes obtaining a signal from a data server, where the data server is monitored by the monitoring facility using a task, identifying a signal characteristic of the signal, and determining a first category for the signal based on the signal characteristic. The method further includes identifying a first signal processing tool for the signal based on the task and the first category and instructing the monitoring facility to perform the task by applying the first signal processing tool to the signal.

Method and system for signal categorization for monitoring and detecting health changes in a database system

A method for processing signals from a data server system including generating, by a monitoring module on a monitoring facility, a plurality of frequency data items, where the monitoring facility comprises a central processing unit, obtaining, by the monitoring module, a first signal value from the data server system, where the signal value is a measurement of an element of the data server system, and calculating a plurality of fit errors for the plurality of frequency data items using the first signal value. The method further includes selecting a frequency data item of the plurality of frequency data items with a lowest fit error to obtain a selected frequency data item, removing a cyclic component of the first signal value using the selected frequency data item to obtain a first processed signal value, and displaying the first processed signal value on a graph.

Method and system for key performance indicators elicitation with incremental data decycling for database management system

In general the invention relates to a method for processing signals from a data server. The method includes obtaining, by a monitoring facility, a measured signal from the data server, wherein the monitoring facility comprises a central processing unit, generating a first probing characteristic from the measured signal, and determining that the first probing characteristic is measureless. The method further includes decomposing, by the central processing unit in response to the determination, the first probing characteristic into a plurality of component parts, constructing a reconstructed signal using a first one of the plurality of component parts, generating a second probing characteristic using the reconstructed signal, wherein the second probing characteristic is not measureless, and processing the reconstructed signal by the monitoring facility.

Diagnostics information extraction from the database signals with measureless parameters

Techniques are described for upgrading systems that include a first set of agents for collecting target data from a plurality of targets and sending the target data to a first management server. In an embodiment, a second set of agents is pre-deployed. Each pre-deployed agent is configured to, upon activation, collect target data from a respective target of the plurality of targets and send the target data to a second management server. While the pre-deployed agent remains inactive, an agent from the first set of agents collects and sends the target data to the first management server. When a first batch of one or more pre-deployed agents is activated, each activated agent begins collecting target data and sending the target data to the second management server. For agents not in the first batch, the first set of agents continues to collect and send the target data.

Upgrading enterprise managers

A method and apparatus for capturing database system workload and replaying that workload in a database system is provided. According to one aspect, in order to subject a test database system to the same workload to which the production database system actually would be subjected, a database server in the production system captures and records workload that the database server receives from external entities. This captured workload is processed. Processes external to a database server in the test database system send the processed workload to that database server. As a result, the test database system is subjected to the same workload to which the production database system originally was subjected. The foregoing technique permits a database administrator to determine how the production database system will fare if the difference that is present in the test database system is introduced into the production database system.

Filtering workload for database replay

Techniques that enable a user or customer at a system site to review and, if desired, modify data identified at the system site for transmission to a diagnosis site prior to the transmission. The identified diagnostic data may be modified such that data that the user does not want to be sent to the diagnosis site (e.g., sensitive data) is excluded from the data communicated to the diagnosis site. The data may be modified by removing or excluding the sensitive data from the data that is communicated to the diagnosis site or replacing the sensitive data with non-sensitive data. The modified data may then be communicated from the system site to the diagnosis site in the form of a package.

Scrubbing and editing of diagnostic data

A method and mechanism for identifying one or more transactions that have modified or created an object in a database system. Also disclosed is a method and mechanism to compensate for the effects of a transaction in a database system is disclosed. The disclosed approach can be applied to perform auditing for changes and/or transactions in a database system and for identifying the scope of changes and data accesses made by a transaction in the system.

Method and mechanism for identifying transaction on a row of data

An infrastructure is provided for gathering diagnostic data that is relevant to an error or other conditions detected in a monitored system. A diagnosability framework is provided that automates the gathering of relevant diagnostic data upon occurrence of the condition in the monitored system. In one embodiment, context data is determined for the condition detected in the monitored system. A rule-based engine is provided that is configured to automatically determine one or more actions to be performed for the condition detected in the monitored system based on the determined context data. The actions may include performing tasks that gather diagnostic data that is relevant to the detected condition, store the gathered diagnostic data in a repository, recommend one or more diagnostic actions to a user, and other diagnostic related actions.

User-triggered diagnostic data gathering

A method, apparatus, and computer readable medium for preserving data dependency during replay of database commands without strictly preserving a global ordering of the database commands is provided. A capture process captures a workload of database commands executed by a production system. The captured workload includes object identifiers that identify database objects that were referenced directly or indirectly during execution of the database commands by the production system. The captured workload also includes an indication of whether the database objects were potentially read or written during execution of the commands. The workload is processed to determine that an object accessed during execution of a command was previously modified during execution of one or more other commands. A replay process on a test database system prevents the command from being replayed until after the one or more other commands have been replayed to modify the object.
