oracle switches temporary table spaces, creates indexes, creates temporary tables, and creates large and small table spaces

1. The temporary table space of the switched database is temp1/the undo table space of the switched database is undotbs01 1. View the table space of the current database select tablespace_name from dba_tablespaces; It was found that there are no above two table spaces. 2. Create temp1 temporary table space and undotbs01 table space #Create […]

[Docker] Linux routing connects two different network segment namespaces, connecting the namespace and the host

If the two namespaces are in different subnets, they cannot be connected through the bridge. Instead, they need to perform Layer 3 forwarding through the router. However, Linux does not provide a virtual router device like a virtual bridge because Linux itself has a router function. The working principle of the router is this: there […]

kspaceSecondOrder mock function

Overview kspaceSecondOrder simulates the time-domain propagation of linear compression waves in a one-, two-, or three-dimensional homogeneous acoustic medium, given four input structures: kgrid, medium, source, and sensor. The calculations are based on an accurate second-order k-space model of the medium with power-law absorption. At each time step (defined by kgrid.dt and kgrid.Nt or kgrid.t_array), […]
