Initialisation failure



I’m trying to get SciDB up and running on a RedHat64 VM. I think that I’ve got almost everything installed and configured but at the end, when, as user scidb, I run the command

I get the response

[code]checking (server 0 (localhost) local instance 0) …
Found 0 scidb processes
This will delete all data and reinitialize storage [n]|y: y

Listing the contents of /home/scidb/DB-SingleInstance/000/0/scidb.log the log ends with the information

2013-06-14 11:47:05,828 [0x7fe5575b9840] [DEBUG]: Created temp directory /home/scidb/DB-SingleInstance/000/0/tmp/ 2013-06-14 11:47:05,843 [0x7fe5575b9840] [ERROR]: System catalog connection failed: SystemException in file: src/system/catalog/SystemCatalog.cpp function: connect line: 1966 Error id: scidb::SCIDB_SE_SYSCAT::SCIDB_LE_CANT_CONNECT_PG Error description: System catalog error. Cannot connect to PostgreSQL catalog: 'FATAL: Ident authentication failed for user "postgres"

but the same log earlier reports

which gives the correct username/password.

I’m completely stumped, not even sure if this is a Postgres issue or a SciDB issue. Any pointers or suggestions would be very welcome at this stage …


Hi Mark,

Sorry about the trouble. Take a look at the User Guide section 2.5.3 - System Catalog Setup. There is a sample pg_hba.conf file provided. It could be that your network/subnet addresses are different. Also consider changing ‘md5’ in the example to ‘trust’ as that sometimes resolves issues. Let me know if that helps.

Thanks Alix

Your answer pointed me in the right direction, I now seem to have a SciDB up and running.
