From everything that you have shown us, you are now happy that access to ZFS filesystems will be slower than they were before. Before you limited ZFS's use of free memory, it was using lots of free memory as a disk cache. Now, you have lots of free memory that is free, but can't be used by ZFS.
Before you made this change and when the databases were running, you had less free memory. Why is that a problem? Was it causing a lot of swapping?
Why buy 64GB of memory if your goal is to keep 49GB free (i.e., unused)?

SYNOPSIS
install-solaris
install-solaris invokes the Solaris Install program. Depending on graphical capability and available memory at the time of invocation,
install-solaris invokes either a text-based installer or a graphical installer.

For SPARC machines:
128 MB
Minimum physical memory for all installation types
128 MB
Minimum physical memory required for windowing system
384 MB
Minimum physical memory required for graphical-based installation
For x86 machines:
256 MB
Minimum physical memory for all installation types
256 MB
Minimum physical memory required for windowing system
512 MB
Minimum physical memory required for graphical-based installation
In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number of fea-
tures available.
install-solaris exists only on the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the for more
