This is from DB2 Manual

Depending on the type of statement you are executing, DB2 will use a
particular package on the server. By default DB2 creates three packages
for each type of package. In this case NULLID.SYSLH2yy is reserved for
statements with CURSORHOLD on and isolation level Cursor Stability. You
can create more packages on the server by connecting to the database
and issuing the following bind command from the /sqllib/bnd directory:

db2 bind @db2cli.lst blocking all grant public sqlerror continue CLIPKG
5
Note: CLIPKG 5 will create 5 large packages, and will give you the
package that your application is looking for, as well as one more in
this case.

You can go all the way upto CLIPKG 30
