Starting the server on UNIX

Note the server
starting directory

Note what directory you are in when you start the server. The server startup
directory determines the location of any database files you create with relative
pathnames. If you start the server in a different directory, Adaptive Server IQ
cannot find those database files.

Any server startup scripts should change directory to a known location before
issuing the server startup command.

Using the startup utility

For most situations, the easiest way to start a database server on UNIX is by
using the startup script that Sybase provides. Using this script ensures that all
required parameters are set correctly, except in special situations described
later in this chapter.

❖

To start the server on UNIX 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 ]

You can also include server switches or database switches, as discussed in the
next section.

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 the version of the
Open Client communications library that is in use, and “possible problems”
messages on failure to start. This message is saved in the stderr log. After that,
all server messages go to the server log. The server log is in
$ASLOGDIR/servername.nnn.svrlog, where nnn is the number of times the
server has been started. See Chapter 1, “Environment Variables and Registry
Entries” in Adaptive Server IQ Reference Manual for a description of
$ASLOGDIR and other environment variables you may need to set.

The

start_asiq

command displays messages as to whether the server started or

not, and

The

start_asiq

utility also adds the appropriate library path to the environment

and sets parameters that govern Adaptive Server IQ. Parameter settings vary
by platform. See your Adaptive Server IQ Installation and Configuration
Guide for a list of parameter settings for your platform.
