Restoring functionality in Adaptive Server

72
To reset or enable options or functionality you had to change before the
upgrade:
1 Reset the configuration parameters.
If you changed any configuration parameters before upgrading, use
to set them back to their previous values.
sp_configure
2 Use
sp_dboption
upgrading.
3 After you complete the upgrade, but before you use the upgraded Adaptive
Server, verify that all scripts developed at your site point to Adaptive
Server 15.0.2.
4 Verify procedure cache allocation after upgrading.
This section is for information only. Adaptive Server ensures that
procedure cache size
the original size was less than the default value.
If you are upgrading from a version of Adaptive Server that is earlier than
version 12.5.x,
procedure cache percent
. Adaptive Server now allocates memory dynamically and
cache size
determines the size of the procedure and data caches in terms of
megabytes. During the upgrade process, Adaptive Server converts the
procedure cache percent
based on this value.
For example, if
procedure cache percent
200MB of memory, then the absolute value of
40MB. During the upgrade process, Adaptive Server converts
at 20 percent to
cache percent
for
procedure cache size
procedure cache size
is set to 10 percent in the example above, and the absolute value
percent
of 10 percent is less than the default value of
procedure cache size
With the introduction of dynamically reconfigured memory configuration
parameters in Adaptive Server 12.5.x, an increase in Adaptive Server's
memory use does not decrease the size of the procedure cache or the data
cache. That is, if your default data cache is set to 40MB, and you increase
your procedure cache, the default data cache is still 40MB.
For more information about
to reset any database options you disabled before
after upgrade is the same as before upgrade, unless
to an absolute value and sets
procedure cache size
is less than the default value, Adaptive Server sets
to the default value. For example, if
is set to the default value.
sp_configure
has been changed to
procedure
procedure cache size
is configured as 20 percent of
procedure cache percent
at 40MB. If the value
