Abstract: In one embodiment, a monitoring device ingests a plurality of data records sequentially from a data stream, each having an associated timestamp, and builds a cluster pattern for a plurality of time periods by placing each data record into a corresponding cluster of a particular time period based on the associated timestamp of each data record. The monitoring device then establishes connection between clusters of different time periods by assigning each data record of each particular time period to both an adjacent preceding and succeeding time period. The monitoring device may detect cluster transitions based on the established connections between clusters of different time periods, and can compute cluster migration metrics based on the cluster transitions. The monitoring device then predicts future cluster migration metrics based on computed cluster migration metrics, detects an anomaly about the predicted future cluster migration metrics, and reacts to the anomaly, accordingly.

Abstract: Techniques are provided for managing cached data objects in a mixed workload environment. In an embodiment, a system, log data is stored in one or more buffers. In response to receiving a request to perform a logical write, a first process writes a first portion of the log data to a log file in persistent storage. While the first portion of the log data is being written to the log file, a second process writes a second portion of the log data in the one or more buffers to the log file in persistent storage. In another embodiment, a request to perform a second logical write may be received before the first logical write completes. While the first log data is being written to the log file, one or more processes write second log data for the second logical write to the log file.

Abstract: An agent manager manages and configures a plurality of agents suitable for execution on different types of applications and server platforms. The agent manager may receive a collection of rules for determining how to deploy, manage and maintain different agents. The agent manager may collect data about the agents and a local machine, communicate with and configure the agents, and communicate with remote machines such as a controller. The agent manager may configure the agents based on one or more rules the agent receives, such as for example a set of rules provided by a controller. The agent manager may parse the received rules, identify any agents that need to be installed or uninstalled, installed agents that need to be turned on, off, or restarted, or agents that should be otherwise modified, for example with an update, a plug-in, a feature enabled or disabled, or some other update.

Abstract: Embodiment provide that each pluggable database (PDB) in a container database is associated with a distinct distributed lock manager (DLM) domain. Thus, in order to access a PDB, a database server instance joins the DLM domain for the PDB. To perform actions on the PDB, the instance secures locks that belong to the DLM domain for the particular PDB. As such, buffers storing data for the PDB may be managed separately from buffers storing data for other PDBs using the PDB-specific DLM domains. An instance forcefully closing a particular PDB marks the DLM domain of the PDB as invalid, which allows detection of the forceful closure by a recovery instance. Detection of an invalid DLM domain by an instance causes the instance to automatically recover the PDB by accessing pertinent ranges of redo logs and replaying changes made to data blocks for the PDB indicated in the logs.

Abstract: A container database stores redo records and logical timestamps for multiple pluggable databases. When it is detected that a first read-write instance of the pluggable database is opened and no other read-write instances of the pluggable database are open, offline range data associated with the pluggable database is updated. When it is detected that a second read-write instance of the pluggable database is closed, and the second read-write instance is the last open read-write instance, the offline range data associated with the pluggable database is updated. The pluggable database is restored to a logical timestamp associated with a restore request based on the offline range data.

Abstract: A method, system, and computer program product for adaptive high-performance database redo log synchronization. The method commences upon performing a write operation of a redo log entry, the write operation concluding with an indication of completion of the write operation of the redo log entry. Any number of committing processes may be waiting for the indication of completion, and upon indication of completion, then (using a first synchronization mode) the processes or proxy measures the waiting time as experienced by the committing processes (e.g., while waiting for the indication of completion of the write operation of the redo log entry). In some cases a second synchronization mode would introduce less latency than the first synchronization mode, so the system changes to a second synchronization mode. The system can also change mode when a predicted second mode waiting time is smaller than the measured waiting time.
