Hi All,
Attaching a new set of patches rebased atop the latest master head and includes
the following changes:
1. Enabling ALTER SYSTEM READ { ONLY | WRITE } support for the single-user,
discussed here [1]
2. Now skipping the startup checkpoint if the system is read-only mode, as
discussed [2].
3. While changing the system state to READ-WRITE, a new checkpoint request will
be made.
All these changes are part of the v2-0004 patch and the rest of the patches will
be the same as the v1.
Regards,
Amul
