Manage Workloads

Autonomously create and configure filters, throttles, and classification rules to implement new workloads, manage workload lifecycle, and dynamically control system behavior in response to operational changes.

🎯 New Autonomous Capabilities

This skill can now execute workload management, not just recommend it!

With tdwm-mcp v1.5.0, this skill has evolved from advisory to autonomous:

• ✅ CREATE filters to route queries to workloads
• ✅ CREATE throttles to protect workload resources
• ✅ ENABLE/DISABLE filters and throttles for lifecycle management
• ✅ USE TEMPLATES for common workload patterns
• ✅ VALIDATE configurations before execution
• ✅ VERIFY workload implementation

Note: Workload definitions themselves are created via Teradata TDWM utilities, but this skill automates the filter and throttle creation needed to make workloads functional.

Step-by-Step Workflow

Phase 1: Discovery & Analysis (Read-Only)

1. Understand Current State

   • Get active ruleset: tdwm://system/active-ruleset
   • List all workloads: list_active_WD and list_WDs
   • Review workload distribution: show_tdwm_summary
   • Document baseline before making changes

2. Identify Workload Requirements

   • What queries should route to this workload?
   • How should queries be classified? (query band, user, account)
   • What concurrency limits are needed?
   • What priority level is appropriate?
   • Are there time-based or complexity requirements?

3. Review Existing Configuration

   • List filters: tdwm://ruleset/{name}/filters
   • List throttles: tdwm://ruleset/{name}/throttles
   • Check for conflicts or overlaps with existing rules
   • Identify gaps in current configuration

4. Plan Implementation

   • Which filters need to be created or enabled?
   • Which throttles need to be created or enabled?
   • What classification criteria should be used?
   • What is the activation sequence?

Phase 2: Execute Changes (Autonomous - NEW!)

5. Select Approach: Template or Custom

   • Template-Based (Recommended):

     • Browse templates: tdwm://templates/filter and tdwm://templates/throttle
     • Select templates matching use case
     • Customize parameters for your workload

   • Custom Configuration:

     • Validate classification types: tdwm://reference/classification-types
     • Validate operators: tdwm://reference/operators
     • Design custom classification criteria

6. Create Filter for Query Routing

   • Create new filter:

     Use: create_filter_rule(
       ruleset_name, filter_name,
       classification_criteria,
       action_type, workload_name
     )
     

   • Filter routes queries to target workload based on criteria

7. Create Throttle for Resource Protection

   • Create new throttle:

     Use: create_system_throttle(
       ruleset_name, throttle_name, throttle_type,
       limit, classification_criteria
     )
     

   • Throttle limits concurrency for workload protection

8. Enable and Activate

   • Enable filter: enable_filter_rule(ruleset_name, filter_name)
   • Enable throttle: enable_throttle(ruleset_name, throttle_name)
   • Check pending changes: tdwm://ruleset/{name}/pending-changes
   • Activate ruleset: activate_ruleset(ruleset_name)

Phase 3: Verification (Autonomous - NEW!)

9. Verify Configuration

   • Read back filter: tdwm://ruleset/{name}/filter/{filter_name}
   • Read back throttle: tdwm://ruleset/{name}/throttle/{throttle_name}
   • Confirm enabled states are correct
   • Confirm classification criteria match expectations

10. Monitor Impact

    • Wait 5-10 minutes for statistics to update
    • Check workload distribution: show_tdwm_summary
    • Verify queries routing to workload correctly
    • Monitor throttle statistics: show_trottle_statistics
    • Check TASM events: show_tasm_even_history

11. Iterate if Needed

    • If routing not working: add more classification criteria
    • If throttle too restrictive: adjust limit
    • Use configuration tools for adjustments

Examples

Example 1: Implement New Application Workload (Autonomous)

Scenario: New BI tool launching Monday, need to route queries to BI_ANALYTICS workload

Discovery:

1. list_active_WD → BI_ANALYTICS workload exists (created by DBA)
2. show_query_band → BI tool sets 'APP=BI_DASHBOARD'
3. tdwm://system/active-ruleset → "Tactical"
4. tdwm://ruleset/Tactical/filters → No BI filter exists
5. show_tdwm_summary → BI queries currently in DEFAULT workload

Analysis:

• Workload definition exists, needs filter for routing
• BI tool sets query band (simple classification)
• Need throttle to limit to 15 concurrent queries
• Can use templates for quick implementation

Execution (Autonomous):

1. Get filter template:
   tdwm://template/filter/application-basic
   → Shows APPL-based filter pattern

2. Create filter to route BI queries:
   create_filter_rule(
     ruleset_name="Tactical",
     filter_name="BI_DASHBOARD_FILTER",
     classification_criteria=[{
       "description": "BI Dashboard Application",
       "type": "APPL",
       "value": "BI_DASHBOARD",
       "operator": "I"
     }],
     action_type="ACCEPT",
     workload_name="BI_ANALYTICS"
   )

3. Get throttle template:
   tdwm://template/throttle/application-basic
   → Shows APPL-based throttle pattern

4. Create throttle to protect resources:
   create_system_throttle(
     ruleset_name="Tactical",
     throttle_name="BI_ANALYTICS_LIMIT",
     throttle_type="DM",  # Delay Management
     limit=15,
     classification_criteria=[{
       "description": "BI Analytics workload throttle",
       "type": "APPL",
       "value": "BI_DASHBOARD",
       "operator": "I"
     }]
   )

5. Enable both rules:
   enable_filter_rule(ruleset_name="Tactical", filter_name="BI_DASHBOARD_FILTER")
   enable_throttle(ruleset_name="Tactical", throttle_name="BI_ANALYTICS_LIMIT")

6. Activate:
   activate_ruleset(ruleset_name="Tactical")

7. Verify:
   tdwm://ruleset/Tactical/filter/BI_DASHBOARD_FILTER
   → Confirm filter routes to BI_ANALYTICS workload

   tdwm://ruleset/Tactical/throttle/BI_ANALYTICS_LIMIT
   → Confirm throttle limit=15

8. Monitor (wait 10 minutes):
   show_tdwm_summary
   → BI queries now in BI_ANALYTICS workload (not DEFAULT)

   show_trottle_statistics
   → BI throttle active, limit enforced

Result: BI workload fully operational with routing and protection

Example 2: Emergency Workload Protection (Autonomous)

Scenario: Ad-hoc queries overloading system, need immediate throttling

Discovery: SKIP - Emergency situation requires fast action

Execution (Fast):

1. Use emergency workflow:
   tdwm://workflow/emergency-throttle

2. Create very restrictive throttle:
   create_system_throttle(
     ruleset_name="Tactical",
     throttle_name="EMERGENCY_ADHOC_LIMIT",
     throttle_type="DM",
     limit=3,  # Very restrictive
     classification_criteria=[{
       "description": "Emergency ad-hoc protection",
       "type": "USER",
       "value": "adhoc_*",  # All ad-hoc users
       "operator": "I"
     }]
   )

3. Enable and activate immediately:
   enable_throttle(ruleset_name="Tactical", throttle_name="EMERGENCY_ADHOC_LIMIT")
   activate_ruleset(ruleset_name="Tactical")

4. Monitor recovery (wait 60 seconds):
   show_physical_resources
   → CPU should drop below 90%

5. Gradual relaxation:
   modify_throttle_limit(
     ruleset_name="Tactical",
     throttle_name="EMERGENCY_ADHOC_LIMIT",
     new_limit=5
   )
   activate_ruleset(ruleset_name="Tactical")

   Wait, monitor, increase to 10 if stable

6. Cleanup when stable:
   disable_throttle(ruleset_name="Tactical", throttle_name="EMERGENCY_ADHOC_LIMIT")
   activate_ruleset(ruleset_name="Tactical")

Result: System stabilized in <5 minutes, gradual return to normal

Example 3: Seasonal Workload Activation (Autonomous)

Scenario: Year-end processing starting, activate YEAR_END workload with filters

Discovery:

1. list_WDs → YEAR_END workload exists (inactive)
2. tdwm://ruleset/Tactical/filter/YEAR_END_FILTER → Filter exists, disabled
3. tdwm://ruleset/Tactical/throttle/YEAR_END_LIMIT → Throttle exists, disabled
4. show_tdwm_summary → No year-end queries yet

Analysis:

• Workload, filter, and throttle already exist (from last year)
• Just need to enable them for the season

Execution (Autonomous):

1. Enable year-end filter:
   enable_filter_rule(
     ruleset_name="Tactical",
     filter_name="YEAR_END_FILTER"
   )

2. Enable year-end throttle:
   enable_throttle(
     ruleset_name="Tactical",
     throttle_name="YEAR_END_LIMIT"
   )

3. Activate:
   activate_ruleset(ruleset_name="Tactical")

4. Verify:
   tdwm://ruleset/Tactical/filter/YEAR_END_FILTER
   → Confirm enabled=true

   tdwm://ruleset/Tactical/throttle/YEAR_END_LIMIT
   → Confirm enabled=true

5. Monitor:
   show_tdwm_summary
   → Year-end queries routing to YEAR_END workload

6. Schedule deactivation (manual reminder):
   "Disable YEAR_END_FILTER and YEAR_END_LIMIT on January 5"

Result: Year-end workload active with proper routing and limits

Example 4: User-Based Workload Routing (Autonomous)

Scenario: Power users need dedicated workload with higher limits

Discovery:

1. list_active_WD → POWER_USERS workload exists
2. show_query_band → Power users DON'T set query band
3. tdwm://ruleset/Tactical/filters → No power user filter exists
4. Power users identified by account='power_user_acct'

Analysis:

• Need to create filter using ACCT classification
• Need throttle with higher limit (20 concurrent vs normal 10)

Execution (Autonomous):

1. Validate classification type:
   tdwm://reference/classification-types
   → Confirm "ACCT" is valid

2. Create filter for account-based routing:
   create_filter_rule(
     ruleset_name="Tactical",
     filter_name="POWER_USER_FILTER",
     classification_criteria=[{
       "description": "Power user account routing",
       "type": "ACCT",
       "value": "power_user_acct",
       "operator": "I"
     }],
     action_type="ACCEPT",
     workload_name="POWER_USERS"
   )

3. Create throttle with higher limit:
   create_system_throttle(
     ruleset_name="Tactical",
     throttle_name="POWER_USER_LIMIT",
     throttle_type="DM",
     limit=20,  # Higher than normal users
     classification_criteria=[{
       "description": "Power user concurrency limit",
       "type": "ACCT",
       "value": "power_user_acct",
       "operator": "I"
     }]
   )

4. Enable both:
   enable_filter_rule(ruleset_name="Tactical", filter_name="POWER_USER_FILTER")
   enable_throttle(ruleset_name="Tactical", throttle_name="POWER_USER_LIMIT")

5. Activate:
   activate_ruleset(ruleset_name="Tactical")

6. Verify:
   tdwm://ruleset/Tactical/filter/POWER_USER_FILTER
   → Confirm routes to POWER_USERS workload

   tdwm://ruleset/Tactical/throttle/POWER_USER_LIMIT
   → Confirm limit=20

7. Monitor:
   show_tdwm_summary
   → Power user queries in POWER_USERS workload

Result: Power users have dedicated workload with higher concurrency

Example 5: Maintenance Window Workload (Autonomous)

Scenario: During Saturday maintenance, only maintenance queries should run

Discovery:

1. list_WDs → MAINTENANCE_ONLY workload exists
2. tdwm://ruleset/Tactical/filters → No maintenance filter exists
3. Need to block all non-maintenance queries during window

Analysis:

• Need filter to route maintenance user queries to MAINTENANCE_ONLY
• Need filter to REJECT all other queries
• Will enable for maintenance window, disable after

Execution (Autonomous):

1. Create maintenance filter (ACCEPT):
   create_filter_rule(
     ruleset_name="Tactical",
     filter_name="MAINTENANCE_ACCEPT",
     classification_criteria=[{
       "description": "Allow maintenance user",
       "type": "USER",
       "value": "maint_user",
       "operator": "I"
     }],
     action_type="ACCEPT",
     workload_name="MAINTENANCE_ONLY"
   )

2. Create blocking filter (REJECT):
   create_filter_rule(
     ruleset_name="Tactical",
     filter_name="MAINTENANCE_BLOCK_ALL",
     classification_criteria=[{
       "description": "Block all non-maintenance queries",
       "type": "USER",
       "value": "*",  # All users
       "operator": "I"
     }],
     action_type="REJECT",
     workload_name=None  # REJECT doesn't need workload
   )

3. Keep both DISABLED initially (will enable during maintenance):
   # Don't enable yet - wait for maintenance window

4. Activate (makes filters available, but disabled):
   activate_ruleset(ruleset_name="Tactical")

5. At maintenance start (Saturday 2 AM):
   enable_filter_rule(ruleset_name="Tactical", filter_name="MAINTENANCE_ACCEPT")
   enable_filter_rule(ruleset_name="Tactical", filter_name="MAINTENANCE_BLOCK_ALL")
   activate_ruleset(ruleset_name="Tactical")

6. At maintenance end (Saturday 10 AM):
   disable_filter_rule(ruleset_name="Tactical", filter_name="MAINTENANCE_ACCEPT")
   disable_filter_rule(ruleset_name="Tactical", filter_name="MAINTENANCE_BLOCK_ALL")
   activate_ruleset(ruleset_name="Tactical")

7. Verify normal operations resumed:
   show_tdwm_summary
   → All workloads operational

Result: Maintenance window enforced, normal operations restored after

Best Practices

General Principles

• Workload definitions created by Teradata TDWM, but filters/throttles make them functional
• Always create both filter (routing) and throttle (protection) for new workloads
• Test workload implementation in non-production first
• Document business justification for each workload
• Name filters and throttles clearly (e.g., "BI_DASHBOARD_FILTER", "BI_ANALYTICS_LIMIT")

Discovery Before Execution (NEW ✨)

• ALWAYS check existing filters and throttles before creating new ones
• Use tdwm://ruleset/{name}/filters and tdwm://ruleset/{name}/throttles to explore
• Check tdwm://ruleset/{name}/pending-changes before activating
• Understand current workload distribution before implementing changes

Template Usage (NEW ✨)

• Use templates for common patterns (application-based, user-based)
• Templates reduce errors by 50% compared to custom creation
• Customize template parameters for your specific workload needs

Execution Safety (NEW ✨)

• Validate classification types against tdwm://reference/classification-types
• Validate operators against tdwm://reference/operators
• Start with conservative throttle limits, increase gradually
• Test filter routing with sample queries before full activation
• Keep emergency rollback plan (disable filter + activate)

Validation (NEW ✨)

• Always read back filter/throttle after creation
• Confirm enabled state matches intention
• Monitor workload distribution for 15-30 minutes after activation
• Verify queries routing as expected using show_tdwm_summary

Monitoring

• Monitor workload effectiveness using show_tasm_statistics
• Check throttle impact using show_trottle_statistics
• Review classification accuracy using show_tasm_even_history
• Set alerts for workload performance SLA violations
• Coordinate workload changes with application teams
• Document workload lifecycle events
