UNSECURE_ONSTAT 1
# Security
# DBCREATE_PERMISSION:
# By default any user can create a database. Uncomment DBCREATE_PERMISSON to
# limit database creation to a specific user. Add a new DBCREATE_PERMISSION
# line for each permitted user.
#DBCREATE_PERMISSION informix
# DB_LIBRARY_PATH:
# When loading a (C or C++) shared object (for a UDR or UDT), IDS checks that
# the user-specified path starts with one of the directory prefixes listed in
# the comma-separated list of prefixes in DB_LIBRARY_PATH. The string
# "$INFORMIXDIR/extend" must be included in DB_LIBRARY_PATH in order for
# extensibility and IBM supplied blades to work correctly.
# DB_LIBRARY_PATH $INFORMIXDIR/extend
# IFX_EXTEND_ROLE:
# 0 (or off) => Disable use of EXTEND role to control who can register
# external routines.
# 1 (or on) => Enable use of EXTEND role to control who can register
# external routines. This is the default behaviour.
#
IFX_EXTEND_ROLE 1 # To control the usage of EXTEND role.
# EILSEQ_COMPAT_MODE:
# When processing characters, IDS checks if the characters are valid
# for the locale and returns error -202 if they are not. This causes
# problems in some applications. This parameter preserves the old
# behavior and permits these characters.
# 0 => Disallow illegal characters. This is the default behavior.
# 1 => Allow illegal characters.

# Dynamic Logging
# DYNAMIC_LOGS:
# 2 : server automatically add a new logical log when necessary. (ON)
# 1 : notify DBA to add new logical logs when necessary. (ON)
# 0 : cannot add logical log on the fly. (OFF)
#
# When dynamic logging is on, we can have higher values for LTXHWM/LTXEHWM,
# because the server can add new logical logs during long transaction rollback.
# However, to limit the number of new logical logs being added, LTXHWM/LTXEHWM
# can be set to smaller values.
#
# If dynamic logging is off, LTXHWM/LTXEHWM need to be set to smaller values
# to avoid long transaction rollback hanging the server due to lack of logical
# log space, i.e. 50/60 or lower.
#
# In case of system configured with CDR, the difference between LTXHWM and
# LTXEHWM should be atleast 30% so that we could minimize log overrun issue.
