A shared SQL area is always in the shared pool. Oracle allocates memory from the shared pool when a SQL statement is parsed; the size of this memory depends on the complexity of the statement. If a SQL statement requires a new shared SQL area and the entire shared pool has already been...

String usage in a shared object can be investigated using strings(1). The following example generates a sorted list of the data strings within the file libfoo.so.1. Each entry in the list is prefixed with the number of occurrences of the string....

In order to create a resource and to bind it to the given loop, just do the following:auto tcp = loop->resource<uvw::tcp_handle>();The line above creates and initializes a tcp handle, then a shared pointer to that resource is returned. Users should check if pointers have been ...
