Oracle ORION: A Storage System Performance Testing Tool

Oracle ORION: Storage System Performance Testing Tool (I) defines ORION (Oracle I/O Calibration Tool) as an Oracle Tool for testing storage system performance bottlenecks because ORION is an independent Tool, it is very easy for users to create and run Oracle Database ORION. You can simply decompress the downloaded package from the official website. http://www.oracle.com/technetwork/cn/topics/index-088165-zhs.html Decompress: # gunzip orion_linux_x86.gz (advantage) ● you do not need to run Load Runner or configure a large number of virtual users ● you do not need to run the Oracle database or prepare a large amount of test data. ● the test results are more representative, for example, in random I/O testing, the software can make the storage hit rate close to 0, and simulate the real IOPS of the disk, which is hard for the load runner to achieve, the final disk IOPS needs to be converted to ● you can customize a certain proportion of write operations as needed (no write operation by default). However, note that if there is data on the disk, be careful when data is overwritten (3) the output file ORION will output 5 files after execution: ● <testname> _summary.txt-Summary of the input parameters along with min. small latency, max large MBPS and/or max. small IOPS. ● <testname> _mbps.csv-Performanceresults of large IOs in MBPS (throughput) ● <testname> _iops.csv-Performanceresults of small IOs in IOPS (IO times per second) ● <testname> _lat.csv-Latency of smallIOs (Response Time) ● <testname> _tradeoff.csv-Shows largeMBPS/small IOPS combinations that can be achieved at certain small latencies ● <testname> _trace.txt-Extended, unprocessed output (trace information, most detailed data) (4) three mandatory parameters for running ORAION must contain run, testname, and num_disks. ● run Type of workload to run (simple, normal, advanced) simple-tests random 8 K small IOs at various loads, then random 1 M largeIOs at various loads. normal-tests combinations of random8K small IOs and random 1 M large IOs advanced-run theworkload specified by the user using optional parameters ● testname Name of the test run ● num_disks Number of disks (physicalspindles) (v) A parameter file is required for the execution of a simple test ORION to specify the disk for testing # cat/dev/sda1> rocky # cat/dev/sda2> rocky #. /orion_linux_x86-run simple-testname rocky-num_disks 1 test result will generate the above five files
