AutoSys Global Variables: 3 Patterns That Work (and 1 That Breaks)

Q: What are global variables in AutoSys?

Global variables are named values stored in the AutoSys Event Server that can be read and written by any job at runtime. They're used to pass information between jobs in a pipeline — record counts, file paths, status flags, and dates. Key properties: persist until explicitly cleared, survive system restarts, accessible via `sendevent SET_GLOBAL`, `autostatus -G`, and `variable()` in JIL conditions.

Q: How do I set a global variable in AutoSys?

Use the sendevent command: `sendevent -E SET_GLOBAL -G "VARIABLE_NAME=value"`. This can be called from within a job's shell script, from the command line, or from another AutoSys job. Example inside a script: ```bash COUNT=$(wc -l < /data/file.txt) sendevent -E SET_GLOBAL -G "RECORD_COUNT=${COUNT}" ``` No spaces around the equals sign. To clear a variable: `sendevent -E SET_GLOBAL -G "VARIABLE_NAME="`.

Q: How do I check the value of an AutoSys global variable?

Use `autostatus -G VARIABLE_NAME`. This returns the current value stored in the Event Server. If the variable doesn't exist, it returns an empty string. To list all global variables: `autostatus -G %`. To filter: `autostatus -G % | grep TRADING`.

Q: Are global variables shared across all AutoSys jobs?

Yes. Global variables are instance-wide — they're accessible to all jobs in the AutoSys instance. This is why naming conventions are critical. Use workflow-specific prefixes (e.g., `TRADING_COUNT` not `COUNT`) to avoid collisions between different teams' jobs. There's no namespace isolation. One workflow's `STATUS` variable will overwrite another workflow's `STATUS` variable.

Q: Do global variables persist between runs?

Yes. Global variable values persist in the Event Server until explicitly changed or cleared. They survive Event Processor restarts, system reboots, and days of calendar time. If you use a global as a flag that should reset each day, make sure your workflow includes a step to reset it at the START of each run (not the end). Better: use date-stamped variable names like `TRADING_FLAG_20260319` so each run has its own unique variable.

Q: What happens if I reference a global variable that doesn't exist in a condition?

`variable(MISSING_VAR)` returns an empty string ''. AutoSys does NOT raise an error. In numeric comparisons, '' is treated as 0. So `variable(MISSING_VAR) >= 0` evaluates as TRUE. Missing variable accidentally passes the condition. Always check existence first: `condition: variable(COUNT) != '' AND variable(COUNT) >= 100`. This pattern ensures the condition only passes when the variable actually exists AND meets the threshold.

Global Variable Lifecycle

Autosys Global Variables

✦ Plain-English analogy ✦ Real code with output ✦ Interview questions

⚡Quick Answer

Global variables are name-value pairs stored in the Event Server — any job can read or write them
Set from a job: sendevent -E SET_GLOBAL -G "COUNT=5432" inside your script
Read in JIL conditions: variable(TRADING_COUNT) >= 1 — data-driven scheduling
Read from command line: autostatus -G TRADING_COUNT
Production killer: globals persist between runs. Monday's COMPLETE flag is still COMPLETE on Tuesday. Reset at workflow start, not end.
Naming convention: TRADING_RECORD_COUNT, not COUNT. Instance-wide — collisions cause silent failures.

AssumptionThe team assumed global variables reset between daily runs. They didn't know globals persist forever unless explicitly cleared or overwritten.

Root causeThe workflow pattern was: 1. Check FLAG at start. If DONE, exit. 2. Process data. 3. Set FLAG='DONE' at end. Monday: FLAG was empty → processed → set FLAG='DONE'. Tuesday: FLAG was still 'DONE' → exited at step 1. The flag was never reset. The workflow checked a condition that persisted from the previous day. No one had documented that globals don't auto-reset.

Fix1. Change pattern: reset at START, not at end. - First job in box: sendevent -E SET_GLOBAL -G "DAILY_FLAG=" (clear it) - Then run main processing - No need to set DONE at end — the next day's reset handles it 2. Add date stamp to flag: FLAG_20260319='DONE' — each run has unique name 3. Monitor: script that alerts if flag is > 24 hours old without a matching run 4. Document: 'Global variables persist until overwritten. Reset at start of each workflow.'

Key Lesson

Global variables persist in the Event Server until explicitly changed.Reset at workflow START, not end. A stale flag from yesterday kills today's run.Use date-stamped global names for per-run state: TRADING_COUNT_20260319.Audit global variables weekly with autostatus -G % to catch stale values.

Production Debug Guide

If your workflow is skipping or behaving strangely, check your globals first

Workflow runs but does no work — completes in seconds. Expected data missing.→Check global flags that control early exit. autostatus -G WORKFLOW_FLAG. If flag is 'DONE' or 'SKIP', your start-of-run reset job likely failed or never ran.

Job condition with variable(COUNT) >= 1 never triggers even though COUNT is high→Check COUNT value: autostatus -G TRADING_COUNT. If COUNT is 0, the setting job may have failed. If COUNT is from yesterday, your reset logic is clearing it too late (at end instead of start).

Different workflows interfering with each other's globals→List ALL globals: autostatus -G %. Look for naming collisions. Fix: rename with workflow prefix. TEAM1_COUNT and TEAM2_COUNT don't collide. COUNT does.

Global variable set in job doesn't persist to next job in box→Check if the setting job succeeded (autorep -J JOB). If it failed, no SET_GLOBAL event was sent. Also check order: setting job must complete before reading job starts — use condition dependencies.

AutoSys global variables live in the Event Server. Any job can read them. Any job can write them. They persist until explicitly changed.

That last sentence is where teams get burned.

A flag set to 'COMPLETE' on Monday is still 'COMPLETE' on Tuesday. A counter that reached 5000 yesterday is still 5000 today unless you reset it. This article covers the patterns that work — and the one stale-value trap that breaks workflows silently.

Setting a global variable from a job

Jobs set global variables using the sendevent command with the SET_GLOBAL event. This can be done from within the job's script or from the command line.

The syntax is: sendevent -E SET_GLOBAL -G "VARNAME=value". No spaces around the equals sign.

Critical: SET_GLOBAL events are processed asynchronously. There's a small delay (typically <1 second) between the command and the value being readable by other jobs. If your downstream job starts immediately after setting a variable, it might not see the value yet. Use condition dependencies to enforce order if timing matters.

set_global.sh · BASH

1234567891011121314

#!/bin/bash
# Script that processes records and sets the count as a global variable

RECORD_COUNT=$(wc -l < /data/processed_trades.csv)

# Set the global variable in AutoSys
sendevent -E SET_GLOBAL -G "TRADE_COUNT=${RECORD_COUNT}"

# For workflows with date-stamped globals (recommended for daily runs)
DATE=$(date +%Y%m%d)
sendevent -E SET_GLOBAL -G "TRADE_COUNT_${DATE}=${RECORD_COUNT}"

echo "Processed ${RECORD_COUNT} trades, set TRADE_COUNT global variable"
exit 0

▶ Output

Processed 5432 trades, set TRADE_COUNT global variable
/* AutoSys: Global variable TRADE_COUNT set to 5432 */
/* AutoSys: Global variable TRADE_COUNT_20260319 set to 5432 */

Mental Model

The Shared Whiteboard Model

The whiteboard doesn't erase itself overnight. If you don't explicitly clear a value, it's still there tomorrow.

Write: sendevent -E SET_GLOBAL -G "NAME=VALUE" — from any job or command line
Read: autostatus -G NAME — returns current value
Clear: sendevent -E SET_GLOBAL -G "NAME=" — empty string removes it
The board persists across days, weeks, restarts. No automatic expiry.

📊 Production Insight

A job set a global variable for downstream consumption. The downstream job had a condition variable(DATA_READY) = 1. The setting job succeeded. The downstream job didn't start.

The issue: The downstream job started at the exact same second as the SET_GLOBAL event was sent. AutoSys processes events sequentially, but condition re-evaluation happens after the event queue settles. The downstream job's check ran before the global was written.

Fix: Add a 5-second sleep in the setting job after the sendevent, or use an intermediate job that does nothing but wait 10 seconds.

Diagnosis: Check job start timestamps in autorep -d. If they're within the same second, you have a race condition.

Rule: SET_GLOBAL is asynchronous. Don't assume the value is readable immediately.

🎯 Key Takeaway

SET_GLOBAL writes to Event Server — asynchronous, not instant.

Use condition dependencies to order setting and reading jobs.

Date-stamped globals (COUNT_20260319) prevent stale-value bugs.

Clear with empty string: sendevent -E SET_GLOBAL -G "NAME=".

Reading a global variable in a JIL condition

You can reference global variables in JIL conditions using the variable() function. This lets you create data-driven conditions.

Syntax: condition: success(job_a) AND variable(TRADE_COUNT) >= 1000 The comparison operators work: =, !=, <, >, <=, >=. String comparison works too: variable(STATUS) = 'COMPLETE'

Critical: variable() returns an empty string if the global doesn't exist. In numerical comparisons, empty string compares as 0. That can cause false positives — a missing variable might silently pass a >=1 check.

/* String comparison with global */
insert_job: check_status

/* Dangerous: missing global passes >= 0 check */
/* If TRADE_COUNT never set, this condition is TRUE */
condition: variable(TRADE_COUNT) >= 0

/* Safer: check existence and value */
condition: variable(TRADE_COUNT) != '' AND variable(TRADE_COUNT) >= 100

/* Set a global variable via sendevent from command line */
# sendevent -E SET_GLOBAL -G "PROCESS_DATE=20260319"

/* Check current value of a global variable */
# autostatus -G TRADE_COUNT

▶ Output

TRADE_COUNT = 5432

⚠ Missing global variables evaluate as empty string — not an error

variable(MISSING_GLOBAL) returns ''. In a numeric comparison like >= 0, '' is treated as 0. Your condition will pass even though the variable was never set. Always check for existence first: variable(COUNT) != '' AND variable(COUNT) >= 100.

📊 Production Insight

A downstream job had condition: variable(FILE_COUNT) >= 5. The upstream job that set FILE_COUNT failed silently. FILE_COUNT never got set. variable(FILE_COUNT) returned '' which AutoSys treated as 0. 0 >= 5 is false, so the condition didn't fire. The workflow stopped. No error. No alert.

The team assumed the condition would error if the variable was missing. It doesn't.

Fix: Change condition to: variable(FILE_COUNT) != '' AND variable(FILE_COUNT) >= 5. Now missing variable fails the condition and can trigger alarms.

Better: Add a validation job that explicitly checks that expected globals are set before downstream runs.

Rule: variable() never errors. It returns ''. Build explicit existence checks into your conditions.

🎯 Key Takeaway

variable(NAME) returns '' if NAME doesn't exist — no error.

Always check existence: variable(NAME) != '' before comparing values.

String comparisons work: variable(STATUS) = 'READY'

Numerical comparisons treat '' as 0 — use existence check to avoid false positives.

Global variable naming, lifecycle, and best practices

Global variables persist in the Event Server until explicitly changed or cleared. They do not reset between daily runs — a value set yesterday is still there today unless something overwrites it. This is both powerful and dangerous.

Lifecycle: Created on first SET_GLOBAL. Persists indefinitely. Cleared by SET_GLOBAL with empty value (or by database cleanup). Survives Event Processor restarts, failovers, and system reboots.

Best practices that separate senior engineers from beginners: 1. Always use a naming convention with a workflow prefix (e.g., TRADING_RECORD_COUNT not just COUNT) 2. Reset flags and counters at the start of each workflow run, not the end 3. For per-run state, include the date in the variable name (e.g., TRADING_COUNT_20260319) 4. Document every global variable your workflow uses — undocumented globals become tribal knowledge 5. Audit global variables monthly with autostatus -G % to catch stale or orphaned ones 6. Never assume a global exists. Check before reading.

Total globals: 12

⚠ Globals do not reset between daily runs — this is the #1 bug

Set a flag to 'COMPLETE' on Monday. Tuesday morning, it's still 'COMPLETE'. Your check at the start of Tuesday's workflow will see 'COMPLETE' and exit early. Always reset globals at the START of each run, not at the end. The reset job is the first job in your box, unconditionally.

📊 Production Insight

A team had 47 global variables in their instance after 3 years of batch workflows. 31 of them were stale — values from workflows that no longer existed, or from runs months ago. No one knew what they were for. Some were still being read by active workflows, causing intermittent bugs when stale values collided with new runs.

The audit: autostatus -G % showed all variables. The team exported them to a spreadsheet. For each variable, they asked: 'What workflow sets this? What workflow reads this? When was it last updated?'

If no one could answer, they cleared it.

After cleanup, 12 variables remained — all documented in a shared wiki with owners, reset patterns, and expected values.

Fix: Add a monthly audit job that lists all globals and flags any last-updated > 30 days ago (requires custom tracking — AutoSys doesn't store timestamps natively, but you can write a wrapper script that logs SET_GLOBAL events).

Rule: Orphaned globals are technical debt. Audit quarterly. Clear what you can't explain.

🎯 Key Takeaway

Globals persist forever — reset at workflow START, not end.

Date-stamped names prevent stale-value bugs entirely.

Audit globals quarterly. autostatus -G % shows everything.

Document naming convention: WORKFLOW_PURPOSE (e.g., TRADING_RECORD_COUNT).

⚠ Common Mistakes to Avoid

✕Using short, generic variable names without workflow prefix

Symptom

Two teams use COUNT in different workflows. One workflow sets COUNT=100. The other reads COUNT and expects a different value. Silent data corruption — jobs run with wrong thresholds.

Fix

Use workflow prefix: TRADING_COUNT, PAYMENT_COUNT, REPORTING_COUNT. Globals are instance-wide. Prefixes are mandatory in production.

✕Not resetting globals between runs — resetting at end instead of start

Symptom

Monday: workflow sets FLAG='DONE' after processing. Tuesday: FLAG still 'DONE' at start. Workflow checks FLAG, sees 'DONE', exits immediately. No data processed. No error. Empty dashboard.

Fix

Reset at START. First job in your workflow clears all globals it will use. Reset job runs unconditionally as the first step.

✕Not checking existence before reading globals in conditions

Symptom

Condition: variable(TRADE_COUNT) >= 100. Upstream job that sets TRADE_COUNT fails silently. variable() returns '' which compares as 0. Condition fails (0 >= 100 is false). Workflow stops. No alert — condition just didn't fire.

Fix

Always check existence: condition: variable(TRADE_COUNT) != '' AND variable(TRADE_COUNT) >= 100.

✕Assuming SET_GLOBAL is instantly readable by downstream jobs

Symptom

Job A sets COUNT=100 then finishes. Job B with condition: variable(COUNT) >= 1 starts immediately and sees COUNT='' because the SET_GLOBAL event hasn't been fully processed yet. Race condition.

Fix

Add explicit ordering: Job A completes, then an intermediate wait job (sleep 5 seconds), then Job B. Or use condition: success(Job A) AND variable(COUNT) >= 1 — AutoSys re-evaluates after the event finishes.

✕Not documenting globals — undocumented globals become tribal knowledge

Symptom

Senior engineer leaves. No one knows what GLOBAL_STATUS_FLAG controls. Workflow breaks. Team spends days reverse-engineering the flag's purpose. Eventually rebuilds it incorrectly.

Fix

Document every global variable in a shared wiki: owner, purpose, expected values, when it's set, when it's read, reset pattern. Audit quarterly.

Interview Questions on This Topic

QWhat is a global variable in AutoSys?JuniorReveal
A global variable is a name-value pair stored in the Event Server that can be read and written by any job in the AutoSys instance at runtime. Key characteristics: - Persists until explicitly cleared or overwritten - Survives Event Processor restarts and system reboots - Accessible via sendevent SET_GLOBAL (write), autostatus (read), and variable() in JIL conditions - Instance-wide — no isolation between different workflows or teams Use cases: Passing record counts, file paths, status flags, or control parameters between jobs in a pipeline.
QHow do you set a global variable from an AutoSys job's script?JuniorReveal
From within a job's shell script, use the sendevent command: ``bash sendevent -E SET_GLOBAL -G "VARIABLE_NAME=value"`Example:`bash COUNT=$(wc -l < /data/file.txt) sendevent -E SET_GLOBAL -G "RECORD_COUNT=${COUNT}"`Critical notes: - No spaces around the equals sign - SET_GLOBAL events are processed asynchronously — there may be a slight delay before the value is readable - The variable persists until explicitly cleared or overwritten - To clear a variable:sendevent -E SET_GLOBAL -G "VARIABLE_NAME="`
QHow do you read the current value of an AutoSys global variable?JuniorReveal
Two ways: 1. From command line: autostatus -G VARIABLE_NAME Returns the current value or empty string if not set. 2. In JIL conditions: condition: variable(TRADE_COUNT) >= 1000 For debugging: - List all globals: autostatus -G % - Pipe to grep for specific prefixes: autostatus -G % | grep TRADING Important: variable() returns empty string for missing variables, not an error. Always check existence in conditions when the variable is critical.
QWhat naming convention would you use for AutoSys global variables?Mid-levelReveal
I use a three-part naming convention: WORKFLOW_PREFIX_PURPOSE Examples: - TRADING_RECORD_COUNT — not just COUNT - PAYMENT_VALIDATION_STATUS — not just STATUS - REPORTING_PROCESS_DATE — not just DATE Why: Global variables are instance-wide. Two teams using COUNT will collide — one workflow's value overwrites the other's. Prefixes prevent collisions and make autostatus -G % output scannable. For per-run state (values that change daily), I add a date stamp: TRADING_COUNT_20260319. This eliminates stale-value bugs entirely because each day's variable has a unique name.
QWhat event type is used to set a global variable in AutoSys?JuniorReveal
SET_GLOBAL with the sendevent command. Full syntax: sendevent -E SET_GLOBAL -G "VARIABLE_NAME=value" The event is written to the Event Server and processed asynchronously. The change becomes visible to other jobs after the event is processed (typically <1 second). To clear a variable: sendevent -E SET_GLOBAL -G "VARIABLE_NAME=" (empty value). You can also set from JIL? No — only from command line or within job scripts. JIL defines job structure, not runtime state.
QHow do you prevent stale global variables from breaking workflows between runs?SeniorReveal
Three patterns: 1. Reset at START, not end: Add a reset job as the first job in your workflow. It runs unconditionally and clears all globals the workflow uses. Example: sendevent -E SET_GLOBAL -G "WORKFLOW_FLAG=" 2. Date-stamped variables: Include the run date in the variable name: TRADING_COUNT_20260319. Each day's run uses a unique variable name. No stale values possible. Downstream jobs read ${VARNAME}_${DATE}. 3. Audit and monitor: Run autostatus -G % weekly. Look for variables older than the expected run window. Alert if a flag is still 'RUNNING' after 24 hours — it means a previous workflow didn't complete or reset correctly. Most robust: Date-stamped names. They eliminate the stale-value problem entirely at the cost of slightly more complex naming.

Frequently Asked Questions

What are global variables in AutoSys?

Global variables are named values stored in the AutoSys Event Server that can be read and written by any job at runtime. They're used to pass information between jobs in a pipeline — record counts, file paths, status flags, and dates.

Key properties: persist until explicitly cleared, survive system restarts, accessible via sendevent SET_GLOBAL, autostatus -G, and variable() in JIL conditions.

How do I set a global variable in AutoSys?

Use the sendevent command: sendevent -E SET_GLOBAL -G "VARIABLE_NAME=value". This can be called from within a job's shell script, from the command line, or from another AutoSys job.

Example inside a script: ``bash COUNT=$(wc -l < /data/file.txt) sendevent -E SET_GLOBAL -G "RECORD_COUNT=${COUNT}" ``

No spaces around the equals sign. To clear a variable: sendevent -E SET_GLOBAL -G "VARIABLE_NAME=".

How do I check the value of an AutoSys global variable?

Use autostatus -G VARIABLE_NAME. This returns the current value stored in the Event Server. If the variable doesn't exist, it returns an empty string.

To list all global variables: autostatus -G %. To filter: autostatus -G % | grep TRADING.

Are global variables shared across all AutoSys jobs?

Yes. Global variables are instance-wide — they're accessible to all jobs in the AutoSys instance. This is why naming conventions are critical. Use workflow-specific prefixes (e.g., TRADING_COUNT not COUNT) to avoid collisions between different teams' jobs.

There's no namespace isolation. One workflow's STATUS variable will overwrite another workflow's STATUS variable.

Do global variables persist between runs?

Yes. Global variable values persist in the Event Server until explicitly changed or cleared. They survive Event Processor restarts, system reboots, and days of calendar time.

If you use a global as a flag that should reset each day, make sure your workflow includes a step to reset it at the START of each run (not the end). Better: use date-stamped variable names like TRADING_FLAG_20260319 so each run has its own unique variable.

What happens if I reference a global variable that doesn't exist in a condition?

variable(MISSING_VAR) returns an empty string ''. AutoSys does NOT raise an error.

In numeric comparisons, '' is treated as 0. So variable(MISSING_VAR) >= 0 evaluates as TRUE. Missing variable accidentally passes the condition.

Always check existence first: condition: variable(COUNT) != '' AND variable(COUNT) >= 100. This pattern ensures the condition only passes when the variable actually exists AND meets the threshold.
