The oninit command (with no flags) initializes shared memory and leaves the database server in on-line mode.
A blank space and a single hyphen ( - ) must follow the oninit keyword if one or more flags are specified. If more than one flag is specified, their effects are additive, and they must be listed without blank separators.
The following oninit flags are used to initialize shared memory only:
| Flag | Effect |
|---|---|
| p | Initializes shared memory but does not delete temporary tables |
| s | Initializes shared memory and leaves the server in quiescent mode |
| X | Initializes the coserver whose coserver number follows the X flag |
| y | Database server or coserver automatically responds yes to all prompts |
These additional flags ofoninit are used to initialize both shared memory and disk space of the server or coserver:
| Flag | Effect |
|---|---|
| i | Initializes disk space and shared memory, leaving the server in on-line mode |
| j | Same as -i, but leaves the server in single-user mode |
| m | Brings up server in microkernel mode, in preparation for a cold restore |
| s | Can be used with -i to leave the server in quiescent mode after disk initialization |
Except for the -j option, which this document describes in Switching to or Starting the Server in Single-User Mode, all the options above are documented in Chapter 7 of the IBM Informix Dynamic Server Administrator's Reference.
The administrator can use the xctl utility to execute these oninit commands across coservers, as described in Chapter 13 of the IBM Informix Dynamic Server Administrator's Reference.
