Issue/Introduction

The spectrumgtw stopped syncing alarms to Spectrum, and after a restart of the probe, the sync failed again after about 1 hour.

Environment

Release : 20.30

Component : spectrumgtw 8.68HF1

Cause

- udm_manager configuration needed adjustment

Resolution

1. Deactivate spectrumgtw.

2. Rename the spectrumgtw cache in the spectrumgtw folder.

3. Activate it.

We also noticed that the udm_manager values were set to the defaults which are too low.

4. Under setup section of the urm_manager configuration file, we set the following parameter->values:

memory_index_max = 516m
memory_index_threshold = 64m
object_cache_max = 256m
heartbeat_interval_msec = 30000

and under startup->opt

java_mem_init = -Xms1024m
java_mem_max = -Xmx2048m

5. Stop discovery_server and udm_manager

6. Drop the datomic_kvs table:

DROP TABLE DATOMIC_KVS;

7. Activate discovery_server
8. Activate udm_manager

Checked to make sure alarms were syncing up with Spectrum and it was back to normal.
