Stree Testing(压力测试)检查被测系统在恶劣环境下的表现,比如内存不足,CPU高负荷,网速慢,等等。在这种情况下,被测系统往往运行缓慢,能暴露许多在高速运行时不易发生的问题,例如线程不同步。 压力测试是测试系统在非正常的、超负荷的条件下的运行情况 ,用来评估在超越最大负载的情况下系统将如何运行,考验系统在正常...
/etc/sysconfig/nfs– It defines the ports needed during the running of RPC services. NFS Server and Client Setup To set upNFSshares, we’ll need at least twoLinux/Unixmachines. Here in this tutorial, I’ll be using two servers. NFS Server–RHEL 9with IP10.128.15.213 NFS Client–RHEL 9...
Random Write:This test measures the performance of writing a file with accesses being made to random locations within the file. Again the performance of a system under this type of activity can be impacted by several factors such as: Size of operating system’s cache, number of disks, seek ...
From time to times, c++ computing tools reported config file not found. Or another result validation tool reported data integrated error. Everything was fine on manually checking. It is caused by cache consistency of NFS. After generating config files, NFS volume mounted on other may be see th...
To cut costs, this articles uses one of the RAC nodes as the source of the shared storage. Obviously, this means if that node goes down the whole database is lost, so it's not a sensible idea to do this if you are testing high availability. If you have access to a NAS or a thi...
The umount command supports the -V option to allow for testing. You might also use the -a option to unmount several file systems at one time. If mount-points are included with the -a option, those file systems are unmounted. If no mount points are included, an attempt is made to ...
Run a memory test using the Windows Memory Diagnostic tool or a third-party memory testing tool to check for RAM problems. Check for Application Conflicts: Certain applications or services running on your system might be conflicting with NFS services. Try disabling or uninstalling third-party ...
The system monitor for these servers is Solstice™ SyMON™, a system performance tool that you can use to: • Monitor the performance of a large server with multiple processors, I/O, and disks. • Optimize the configuration and throughput of the server. • Identify hardware and ...
Functionality testing was similar to work done in the previous versions of the solution (4). A 64 node HPC cluster was used to provide I/O workload to test the performance of the NSS-HA. The performances of the 144TB and 288TB solutions were measured against this test bed for both ...
