c-treeACE V10.0 Update Guide

General File I/O Improvements

The File I/O subsystem has a number of other improvements:

• Create directories - We can now automatically create directories that do not exist when creating data and index files.
• External processes - On Windows, we now prevent external processes from accessing open files.
• ctREADFIL - Improve ctREADFIL sharing modes and introduce new read/write access mode with read-only sharing.
• File block check - Improve speed of c-treeACE Server opening files by skipping file block check when no file blocks are active.
• Shared Reopen - Permit Shared Reopen after a Transaction Controlled Header is updated.
• Unlock request - Ignore the persistent transaction lock state when an unlock request is made outside a transaction.
