Maintenance Tasks Overview

To run server-side tests in ALM, the lab system must be up and functioning correctly. Scheduled automated maintenance tasks provide constant monitoring of the system's key components in order to detect system failures. You use the Maintenance Tasks module to check the status of the system.

The following table describes the maintenance tasks:

UI Elements (A - Z)

Description

Check Host Task

Verifies the host installation, and updates the host status to either Operational or Non-Operational.

Default frequency: Every 24 hours

Data Processor Task

Sets and updates a data processing queue for any of the following actions: Analyzing a test run, recalculating the SLA, or adding test runs to a trend report.

Default frequency: Every minute

Handle Non Polling Functional Hosts Checks the Last Poll Time field of all registered Functional testing hosts. If a testing host has not been active for a long time, this task changes the status of the testing host to Idle or Non-Operational.
OFW Status Update Task

Updates the real status (Operational or Non-Operational) of a host that is located over a firewall.

Default frequency: Every 15 minutes

Orphan Run Task

Identifies orphan test runs during and outside of the active timeslot.

Default frequency: Every 15 minutes

Resource Recovery Task

Performs predefined validation tests on Controllers and load generators that are in the Non-Operational state. If the host passes the test, its status changes to Operational.

  • Controller validation tests. Tests the OTA connection, ability to run, and available disk space.

  • Load Generator validation tests. Tests the connection to the agent.

The task parameters should be within the following guidelines:

  • MIN_APPLICATION_DIR_DISK_SPACE: Between 10 and 1000

  • CHECK_LG_TIMEOUT: Between 1 and 15

  • MAX_RETRIES: Between 1 and 1000

Default frequency: Every 15 minutes

Note: For load generators over a firewall, this is performed by the OFW Status Update task (see above).

Result Cleaning Task

Cleans test run results from Controllers or load generators in the following instances:

  • If the results have already been collated.

  • There are old performance tests whose results were not collated.

  • If the performance test was deleted.

The RESULT_EXPIRY_DAYS task parameter should be between 1 and 1000.

Default frequency: Every 6 hours

Synchronize Lab and SA times Finds the time difference between Lab Management and Site Administrator and enters it into the parameter SA_LAB_TIME_DIFF_MILLIS in the DATACONST table.
