Sybase recommends that you use the startup utility, start_asiq or Sybase Central to start servers. This command-line utility runs on all platforms, and ensures that all required parameters are set correctly, except in special situations described later in this chapter.
The general form for the startup utility is as follows:
start_asiq [ server-options ] [ database-file [ database-options ], ...]
The elements of this command line are as follows:
server-options include the database server name and other options that control the behavior of the server, for all databases that are running on that server.
database-file is the file name of the Catalog Store. You can omit this option, or enter one or more database file names on the command line. Each of these databases is loaded and available for applications. If the starting directory contains the database file, you do not need to specify the path; otherwise, you must specify the path. You need not specify the .db file extension.
database-options are options that you can specify for each database file you start, that control certain aspects of its behavior.
In examples throughout this chapter where there are several command-line options, we show them for clarity on separate lines, as they could be written in a configuration file. If you enter them directly on a command line, you must enter them all on one line (that is, without any carriage returns).
See “Using command-line switches” for a descriptions of configuration files and commonly used options.
You can choose from many command-line switches to specify such features as permissions required to start a database or stop the server, and the network protocols to use. The command-line options are one means of tuning Sybase IQ behavior and performance.
For ease of use, start the database
and server together, by specifying the database name when you start
the server. The server takes its name from the database name by
default, or you can specify a different name for the server. See “Naming the server and databases” for more information
on server and database names.
To start the server without starting any database, omit the database file from the start_asiq command and specify a servername. If you omit the database name, you must name the server explicitly using the -n server switch. Use this method when you create or restore a database, or when you only want to control starting and stopping the server, leaving database use to client software.
Starting the server using the startup utility
Change to a writable directory.
Run the start_asiq utility at the system prompt. The simple form of this command is:
start_asiq servername [ database ]
This command starts the named server as a background process, starts the named database if you specify it, and sets all required startup options. Once the server starts, it sends a message to the window or console where you started the server indicating that the server is running. It also displays other information about your server environment, as well as “possible problems” messages on failure to start. For an example of the version string and other startup messages, see “Message logging” in Chapter 1, “Overview of Sybase IQ System Administration.”
All server messages go to the server log. By default, is $ASLOGDIR is defined, the server log is in $ASLOGDIR/servername.nnn.srvlog, where nnn is the number of times the server has been started. You can also name the server log using the -o startup option.
