# 1. Cannot set the pager_ota_mode flag on a WAL mode database.

# 2. Or if there is an open read transaction.
|

|
|
# 3. Cannot start a transaction with pager_ota_mode set if there
|
|
# is a WAL file in the file-system.
|
|
#
|
|
# 4. Or if the wal-mode flag is set in the database file header.
|
|
#
|
|
# 5. Cannot open a transaction with pager_ota_mode set if the database
|
|
# file has been modified by a rollback mode client since the *-oal
|
|
# file was started.
