Hello, all Is it possible to receive 08001 error for any other reason that network problems? We know that the server is running and sometimes users get this error: ERROR [08001] [Sybase][ODBC Driver][SQL Anywhere]Database server not found It goes on for a few seconds and then comes back as if there was never a problem. So, could it be anything else other than network issues? The IT dep tells us (what a shock...) that there are no network problems. Thank you Arcady |

The v16 docs list many such errors, for example: Error constant SQLE_UNABLE_TO_CONNECT ODBC 2 state 08001 ODBC 3 state 08001 Parameter 1 Reason that database cannot be started. Severity 11 SQLCODE -105 SQLSTATE 08001 Sybase error code 4001 The specified database cannot be started. Either it does not exist, it is not a database, it is corrupt, or it is an older, unsupported format. Therefore please check the SQLCODE or SQLSTATE error codes of the error you receive, they should be more specific... For the error message "Database server not found" aka SQLCODE -100 you get:
Using the LOG connection parameter on your client connection string seems worthwhile. I read the manuals, thank you. I as asking if this particular error with this particular description can be returned on any event other than network error.

Ah, I see. While I cannot answer that, I still suggest to use the LOG parameter (and possibly the -z database server option to log on that side, as well).

So, "not being able to find it" can be for any other reason other than network error, providing that the DB service is up and running and servicing other connections?

OK, I managed to recreate the problem with the log file I am not sure it brought me closer to understanding the source of the problem. Why does it say "verification of server name failed"? Both machine and db server name are correct. Will setting verify=no help in this case? These are the contents of the log: //------------------------------------ Attempting to connect using: UID=MetaSearch;PWD=********;DBN=g4_center_astral;ServerName=g4_center_astral;CON=PricesInternalService;LOG=C:\Temp\center_astral_20190226_11.txt;Host=vm-g4-db-05:2639 12:23:05 Attempting to connect to a running server... 12:23:05 Attempting TCPIP connection (address 10.10.100.65:2639 found in sasrv.ini cache) 12:23:05 Looking for server with name g4_center_astral 12:23:05 Trying to find server at cached address 10.10.100.65:2639 without broadcasting 12:23:08 Verification of server name failed 12:23:08 A HOST value was specified, skipping LDAP check 12:23:08 Failed to connect over TCPIP 12:23:08 Removing failed address from sasrv.ini cache 12:23:08 Not attempting to autostart server //-----------------------------------

Is the contents of the sasrv.ini file correct, i.e. has the dababase server "g4_center_astral" the address "10.10.100.65:2639"? Otherwise it seems that the cache routes the connection attempt to a wrong address and therefore fails. If so, try omitting the .ini cache... As the .ini file is stored locally, that could explain why different clients can resp. cannot reach the database server, even if they you exactly the same connection string.
