Archive Manager is down in OneClick Connection Status - validating database

Products

• CA Spectrum

Issue/Introduction

Recently the SpectroServer and OneClick server have been restarted.

After starting in Spectrum OneClick console, events are not shown, with error as "Achieve Manager is not available."

In spectrum control panel, Archive Manager is in start state.

Note: If you have Secondary ArchiveManager configured the status may show Switched. 

Cause

The Archive Manager is validating the DDMdb database.

When reviewing the $SPECROOT/SS/DDM/ARCHMGR.OUT file it contains just a couple of lines:

Apr 30 09:35:06 : ArchMgr started as user 'user'
Apr 30 09:35:06 : ArchMgr validating database.

Environment

Release: 20.2.x

Component: SPCAEM - Events and Alarms

Resolution

If either the previous Archive Manager shutdown was not successful or the Archive Manager database (DDMdb) was repaired, the next time the Archive Manager is started, it will validate the DDMdb database.

This validation operation will take time depending on the DDMdb database size. Check the size of the $SPECROOT/mysql/data/ddmdb/event.MYD file.

Follow the steps below to query the MySQL server to list what threads are running:

1. Log into the system as the user that owns the Spectrum installation

2. If on Windows, start a bash shell by running "bash -login"

3. cd to the $SPECROOT/mysql/bin directory

4. Enter the following command to log into mysql:
    
    Linux: ./mysql --defaults-file=../my-spectrum.cnf -uroot -proot ddmdb
    Windows: ./mysql -uroot -proot ddmdb

5. Run the following command at the mysql prompt:

    show full processlist\G


In the example below the MySQL server is checking the event table:

Once the validation is completed successfully, you will be able to access the Archive Manager database.
