Users permitted to change modes

UNIX only

Users who are logged in as root or informix and members of the DBSA group can change the operating mode of the database server.

If you want users with the DBSA group to connect to the database server in administration mode, set the ADMIN_USER_MODE_WITH_DBSA configuration parameter to 1. If this parameter is set to zero, then access is restricted to user informix only. If the parameter is missing from $ONCONFIG, it is treated as 0.

User informix or a DBSA can dynamically give one or more specific users the ability to connect to the database server in administration mode, using the onmode utility, the oninit utility, or the ADMIN_MODE_USERS configuration parameter.
Note: For a member of the DBSA group, the permissions on $INFORMIXDIR/bin/oninit must be changed to allow public execute permission - root:informix:6755 in a standard HCL Informix® installation.

Windows only

Table 1 shows which users can change the operating mode of the database server in Windows. Apache as user informix. The Apache server runs as a member of the Informix-Admin group.
