Hi @SanjulaGanepola
For the newly added SQL Packages, the "Get Authorities" action is super duper slow performer.

Could you please change:

SELECT authorization_name "User profile name", object_authority "Object authority",
owner "Object owner", authorization_list "Authorization list", primary_group "Primary group",
authorization_list_management "Authorization list management",
object_owner "User is object owner", object_operational "Object operational authority",
object_management "Object management authority",
object_existence "Object existence authority", object_alter "Object alter authority",
object_reference "Object reference authority", data_read "Data read authority",
data_add "Data add authority", data_update "Data update authority",
data_delete "Data delete authority", data_execute "Data execute authority",
text_description "Description"
FROM qsys2.object_privileges
WHERE object_schema = 'QSYS' AND object_name = 'QSQLPKG2' AND sql_object_type = 'PACKAGE'

To

SELECT authorization_name "User profile name", object_authority "Object authority",
owner "Object owner", authorization_list "Authorization list", primary_group "Primary group",
authorization_list_management "Authorization list management",
object_owner "User is object owner", object_operational "Object operational authority",
object_management "Object management authority",
object_existence "Object existence authority", object_alter "Object alter authority",
object_reference "Object reference authority", data_read "Data read authority",
data_add "Data add authority", data_update "Data update authority",
data_delete "Data delete authority", data_execute "Data execute authority",
text_description "Description"
FROM qsys2.object_privileges
*WHERE system_object_schema = 'QSYS' AND system_object_name = 'QSQLPKG2' AND object_type = 'SQLPKG'

The predicate approach is a game-changer for performance.

Also, same comment on object locks for the "Get Object Locks" action.
The current predication is super slow.
SELECT system_table_member "Member", member_lock_type "Member Lock Type", lock_state "Lock State",
lock_status "Lock Status", lock_scope "Scope",
SUBSTR(job_name, LOCATE_IN_STRING(job_name, '/', -1) + 1) "Job Name",
SUBSTR(
job_name, LOCATE_IN_STRING(job_name, '/', 1) + 1, LOCATE_IN_STRING(job_name, '/', -1) -
LOCATE_IN_STRING(job_name, '/', 1) - 1) "Job User",
SUBSTR(job_name, 1, LOCATE_IN_STRING(job_name, '/', 1) - 1) "Job Number", thread_id "Thread",
lock_space_id "Lock Space", lock_count "Lock Count", program_library_name "Program Library",
program_name "Program Name", module_library_name "Module Library", module_name "Module Name",
procedure_name "Procedure Name", statement_id "Statement ID",
machine_instruction "Instruction"
FROM qsys2.object_lock_info
WHERE object_schema = ? AND object_name = ? AND sql_object_type = ?

If you change these to use system_object_schema , system_object_name, and object_type... the performance improvement will be amazing.

Please change the predication of actions as noted in the comments that I posted.
