Inventory troubleshooting

See the following information to troubleshoot Inventory service issues.

Inventory not reachable after upgrade

When upgrading from Agile Service Manager Version 1.1.17 (which introduced the inventory service) to either version 1.1.18 or 1.1.19, the Resource Manager displays an error message: Inventory service is not reachable

The inventory log displays the following entry:
org.flywaydb.core.api.exception.FlywayValidateException: Validate failed: Migrations have failed validation
Migration checksum mismatch for migration version 1.0
Workaround
  1. Open the $ASM_HOME/etc/nasm-inventory.yml file.
  2. Change the FLYWAY_VALIDATE_MIGRATE parameter to false.
  3. Restart Agile Service Manager using the asm_stop.sh and asm_start.sh commands.
Note: This error does not occur when upgrading to Agile Service Manager Version 1.1.20, because the Flyway validation parameter for v1.1.20 is set to 'false' by default.

Repopulating Inventory

If data in the PostgreSQL database is out of sync with data in the Cassandra database, rebroadcast the data. This triggers the rebroadcast of all known resources on Kafka, and the Inventory service will then store those resources in PostgreSQL.
UI workaround
To resynchronize data using the UI, run the Rebroadcast administration routine from the Topology configuration page, as described in the Running data administration routines topic.
Manual workaround
To resynchronize data manually, call the rebroadcast API of the topology service, specifying a tenantId:
