Starting the server

To start the server, change to a directory where you have write privileges and run the start_asiq utility at the command prompt, using the following command format:

start_asiq @configuration_filename.cfg dbname.db

This command starts the database and sets parameters named in the (optional) configuration (.cfg) file.

NoteIf Adaptive Server Anywhere is installed on the same subnet as Sybase IQ, you must change the default port number for IQ; both products use the default port of 2638. First, set a new port number in the $ASDIR\scripts\default.cfg file. Then update each IQ database configuration file (for example, ASDIR\demo\asiqdemo.cfg) by changing the port number in the following line:

-x tcpip{port=2638}

Change to an unused number, for example, 4444:

-x tcpip{port=4444}

You can use a configuration file to specify options that you want to set whenever you start your server. A configuration file for the sample database is installed in the $ASDIR/demo directory as an example. For details about configuration files, see “Setting server configurations”.

NoteThe directory where the server is started becomes the default directory for all server files created by Sybase IQ.

For example, to start the sample database installed with the product, you could use these commands:

% cd $ASDIR/demo
% start_asiq @asiqdemo.cfg asiqdemo.db

NoteThe server name may not start with a number.

Startup information, which includes the version of Open Client Libraries in use, is saved in the stderr log. Output from start_asiq ends with this line:

Server started successfully

For more information, see Sybase IQ System Administration Guide.

NoteIf you run the start_asiqutility from $ASDIR/bin, the script changes directory to “./..” to avoid creating database files in the /bin directory.

Using defaults in $ASDIR/scripts/default.cfg, the start_asiq utility sets any required environment variables that have not been set and sets parameters that govern Sybase IQ to the recommended defaults. If you start your server using any command other than start_asiq, or if your configuration file is encrypted, you must specify the following parameters:

Table 1-6: Parameters set by start_asiq

Parameter

-gm

Client time-out set to 72 hours

For a complete list and description of parameters, see “The database server” in Chapter 2 of Sybase IQ Reference Manual.

NoteDo not discard this document after installing Sybase IQ. You may need these required parameters later.

If you have Sybase Central, you may use the Start Database Server wizard, as documented in Introduction to Sybase IQ, instead of start_asiq.

NoteOn UNIX systems, always run Sybase Central Java and dbisql using the default colors of the Common Desktop Environment. Running these products under Open Windows or changing the default colors may cause display problems.

The server process runs in the background. It sends output to a server log file, $ASLOGDIR/servername.NNN.srvlog where NNN is the number of times the server has been started. For example, $ASLOGDIR/fiona.123.srvlog.

NoteOn the start_asiq command line, the last option specified takes precedence, so if you want to override your configuration file, list any options you want to change after the configuration file name. For example:

start_asiq @asiqdemo.cfg -x 'tcpip{port=1870}' asiqdemo.db

The –x parameter here overrides connection information in the asiqdemo.cfg file.
