Well, I can help with part of your question:
All CLI packages start with SQLL, the dynamic packages have a format of SQLLyzxx
y = Size and cursor hold:
F - small with hold
C - small no hold
D - big with hold
E - big no hold
z = Isolation level:
0 - Cursor Stability
1 - No Commit (as/400 only)
2 - uncommitted read
3 - read stability
4 - repeatable read
xx = copy number in hex
Have you checked to see if this package is actually missing? Sometimes, it is there but the user doesn't have execute privilege.
