If you see the Webcenter Space app (Webcenter.ear) from the WebLogic console, the session timeout (3,600 seconds) session timout is misleading and is not applicable in the case of webcenter space applications. If you update the value from the console, it does not affect the session time-out of the Webcenter space application. Then, the question is how can I change the Webcenter space app session timeout? The default session timeout in Web. XML is set to 45 minutes. There are two ways to change t

Each operating Oracle database corresponds to an Oracle instance (or routine). Each instance allocates its own memory structure and process structure when it starts; 3.

L Preface The management of Oracle memory, up to 9ir2, is a very important aspect, mismanagement, will likely cause serious performance problems to the database. We'll take a step-by-step approach to all aspects of memory management. L Overview Oracle memory can be divided into the system global zone and the process global area in terms of shared and private, that is, the SGA and the PGA (process global area or private global areas). For memory

Similarly, the PGA can be judged.Summarize:11G later introduced the memory_max_target and memory_target parameters for automatic memory management (Automatic memories Management), In fact, the allocation of SGA and PGA is determined by the respective parameters, such as Sga_target, Sga_max_size, Pge_aggregate_target. The PGA and SGA default values are actually

when we are doing database connection operations. Let's take a look at Oracle's instance memory structure Third, instance memory structure and process structure ( because the memory structure and the process structure are closely related, the process will affect the corresponding memory region, such as the database writer acting in the database buffer cache, the log writer will act on the log buffer, so the memory structure and process structure will be described in conjunction with each other)
