Hi,

I cannot check on the 10.7 release docs right now, I get 'Service
Unavailable' on wiki access, but I suspect I last did anything in this
area. As far as I remember, it was a manual approach of loading up some
randomly created database, kick off some process (I might have started one
of the system tests for this), then crashing the jvm (killing the jvm), and
then using ij, check the database (likely I just did some simple operations
(create, delete, select, update), and probably consistency checker).

Unless someone knows another approach that was done under this heading...

Myrna

We do have a crash recovery test for encrypted databases (CryptoCrashRecove=

<br>
I have some questions for the Store experts:<br>
<br>
1) Does &quot;Recovery after crashing engine&quot; mean running CryptoCrash=
Recovery on the debug distribution of 10.11.1.1?<br>
<br>
2) Does it entail some other, formal tests?<br>
<br>
3) Or is it meant to cover some other ad-hoc tests which are run by hand an=
d are not checked in under subversion?<br>
