After a successful upgrade of the primary SpectroSERVER to 10.02.00 in a Fault Tolerant environment, the primary SpectroSERVER crashes soon after starting. 


The following is an example of what is seen in the stack trace of the dmp/core file

Upgrading to Spectrum 10.02.00 on Windows or Linux


The Primary SpectroSERVER has a new snooze alarm functionality that is conflicting with the secondary SpectroSERVER that does not yet have this new functionality.









 The Spectrum 10.02.00.PTF_10.2.003 patch is available to prevent the crash from occurring. The following is from the Spectrum 10.02.00.PTF_10.2.003 patch release notes:

Symptom: Spectrum 10.2 crashed with AlarmSnoozeService in the stack trace. 

Resolution: The SpectoSERVER will no longer crash.


Please contact CA Spectrum Support for a copy of the Spectrum 10.02.00.PTF_10.2.003 patch.

This issue has been fixed in CA Spectrum 10.2.1 release:
Symptom: Spectrum 10.2 crashed with AlarmSnoozeService.
Resolution: The SpectoSERVER will no longer crash with AlarmSnoozeService.
(10.2.1, DE265177, 00633417)

Additional Information

Recover from possible database corruption.


If the patch is installed after the SpectroSERVER has crashed, you will need to recover from possible database corruption prior to starting the SpectroSERVER process. During the installation of Spectrum 10.02.00, there will be three new database files created in the $SPECROOT/SS directory:


legacy.SSdb - This database file is a catalog only database containing a clean catalog from the installation. A new legacy.SSdb file is created every time a Spectrum installation is run. The version of the legacy.SSdb file will be the version of Spectrum installed at that time.


There will be a file date/time stamped with the word "after" in the file name. For example, "db_20170111,1.after.SSdb". This is commonly referred to as the ".after" database file. This is also a catalog only database containing a clean catalog from the installation.  The version of the .after file will be the version of Spectrum installed at that time. 



There will be a file date/time stamped that will contain the models and catalog of the previous version of Spectrum installed. For example, "db_20170111,1.SSdb". If installing Spectrum 10.02.00 over the top of Spectrum 10.01.01, this database will be version 10.01.00, 

Please do the following to recover from possible database corruption after the crash and after installing the PTF_10.02.003 patch:


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

2. On Windows, open a bash shell by running "bash -login"

3. cd to the $SPECROOT/SS directory

4. Remove the $SPECROOT/SS/.VNMDB.LOCK file

5. Run the following command to initialize the database to the legacy catalog:



../SS-Tools/SSdbload -il legacy.SSdb


6. Run the following command to load the models only from the models and catalog save from before the upgrade was done: 

../SS-Tools/SSdbload -m <models and catalog database save from the previous version of Spectrum>

                Example: ../SS-Tools/SSdbload -m db_20170111,1.SSdb



7. Start the SpectroSERVER as normal.

It is highly recommended to make a new full database save that will now be of a database having 10.02.00 and PTF_10.02.003 installed.
