Execute the oninit utility from the command line to initialize database server shared memory and bring the database server online. If you use oninit options, you can also initialize disk space.
On UNIX, you must be logged in as root or user informix to execute oninit. On Windows NT, you must be a member of the Informix-Admin group.
Before you initialize the database server, set the INFORMIXSERVER environment variable to the dbservername that you chose when you set the configuration parameter DBSERVERNAME. INFORMIXSERVER is not required for initialization. However, if INFORMIXSERVER is not set, the database server does not build the sysmaster tables. Also, the DB-Access utility requires INFORMIXSERVER to be set.
For information about what happens during initialization, see the chapter on initializing the database server in the IBM Informix: Administrator's Guide.
On Extended Parallel Server, you can perform oninit operations on specific coservers. Use oninit with xctl to initialize multiple coservers or to initialize a coserver on a node that is different from your login node. You can also bring up the database server or coserver in microkernel mode (oninit -m).
