Insufficient key column information for updating
For additional system variable information, see these sections: Some system variables control the size of buffers or caches.
For a given buffer, the server might need to allocate internal data structures.
Additionally, the formula should probably be extended: total = innodb_buffer_pool_size key_buffer_size innodb_additional_mem_pool_size innodb_log_buffer_size max_connections * (sort_buffer_size read_buffer_size binlog_cache_size maximum_thread_stack_size); Noting that "key_buffer_size" is a My ISAM parameter there is abug in My SQL server that treat open_files_limit and open-files-limit differently also the limit for open-files-limit mentioned on this page is not entirely true appears that the "read_buffer_size" setting is used by the MEMORY table engine as the allocation increment size (minus a few bytes).
This means that a MEMORY table with *one row* will take up, essentially, "read_buffer_size" bytes.
I've been working on xterm since early 1996 (see my changelog for details). A lot of people, cited at the bottom of the manual page wrote the original xterm program, maintained by the X Consortium (later part of The Open Group – I'm well aware of the distinction, but am citing when the work was done, not who the current owner may be).
There is no changelog, and it is not clear who did what.
At runtime, setting the global value of a system variable normally requires the This section provides a description of each system variable.Email from Jim Gettys (September 1998) provides some background: Cast of thousands... It was originally written as a stand-alone terminal emulator for the VS100 by Mark Vandevoorde, as my coop student the summer that X started.Part way through the summer, it became clear that X was more useful than trying to do a stand alone program, so I had him retarget it to X.Error output can be directed to a file or the console in addition to or instead of the system log as desired.
