This screen provides summary I/O information for all processes activated to collect global statistics using the Process Monitoring facility. The processes displayed on this screen have previously activated their global statistics collection. Process global statistic collection can be either implicitly activated by the database monitor, or explicitly activated by the RMU Show Statistic utility. This screen provides the following information: o Process.ID The process ID for the current process, assigned by the operating system, and the stream ID, assigned by the database. If "G" is appended to the process ID, the process had been activated for global statistics collection; this is the normal case. Server processes will be designated with the "s" tag. o Sync.Reads This field gives the number of synchronous read QIOs (queued I/O requests) issued to the database storage area for single-file and multifile databases and snapshot files. This operation reads database pages synchronously from the database. o SyncWrites This field gives the number of synchronous write QIOs (queued I/O requests) issued to the database storage area for single- file and multifile databases (.RDA) and snapshot files (.SNP). This operation writes modified database pages synchronously back to the database. o Read.Stall This field gives the time in hundredths of a second spent reading database pages from the database rootfile (.RDB), storage area (.RDA) files and snapshot (.SNP) files. An excessively high number often indicates disk contention that might be alleviated by moving some files to other disks. This statistic field includes both synchronous and asynchronous I/O read stall durations. o WriteStall This field gives the time in hundredths of a second spent writing database pages to the database rootfile (.RDB), storage area (.RDA) and snapshot (.SNP) files. An excessively high number often indicates disk contention that might be alleviated by moving some files to other disks. This statistic field includes both synchronous and asynchronous I/O read stall durations. o AsyncReads This field gives the number of asynchronous read QIOs (queued I/O requests) issued to the database storage area for single- file and multifile databases (.RDA) and snapshot (.SNP) files. This operation reads database pages asynchronously from the database. o AsyncWrits This field gives the number of asynchronous write QIOs (queued I/O requests) issued to the database storage area for single- file and multifile databases (.RDA) and snapshot files (.SNP). This operation writes modified database pages asynchronously back to the database.
