# Root Dbspace Configuration
ROOTNAME rootdbs # Root dbspace name

ROOTOFFSET 0 # Offset of root dbspace into device (Kbytes)
# On some UNIX platforms, it is an error to set ROOTOFFSET to 0.
# When this parameter is incorrectly set, you might have to
# reinitialize the disk space and reload the data before
# resuming proper operation of the database server.
# Always check the machine notes to get machine-specific information
# before setting your configuration parameters.

# see the last line of output from the command: 'onstat -b'.
# Recovery Variables
# OFF_RECVRY_THREADS:
# Number of parallel worker threads during fast recovery or an offline restore.
# ON_RECVRY_THREADS:
# Number of parallel worker threads during an online restore operation
OFF_RECVRY_THREADS 10 # Default number of offline worker threads

RA_THRESHOLD # Number of pages left before next group
IDX_RA_PAGES # Number of index pages to attempt to read ahead
IDX_RA_THRESHOLD # Number of index pages left before next group
# DBSPACETEMP:
# This is the list of dbspaces
# that the SQL Engine will use to create temp tables, etc.
# The list can be specified using various preset "sets" that are
# ALL - all dbspaces can be used for temp files
# TEMP - use only temporary dbspaces for temp files
# NOTCRITICAL - use only noncritical dbspaces for temp files
# Critical dbspaces are the root dbspaces and dbspaces containing
# log files.
# The list can also be specified as an explicit list of dbspaces/dbslices
# that exist when the database server is brought online. If not specified,
# or if all dbspaces specified are invalid, various ad hoc queries will create
# temporary files in /tmp instead. If a dbspace in this list is
# added to the system at a later point in time, it is automatically added
# to the list of dbspaces that can be used for temp purposes.
DBSPACETEMP NOTCRITICAL # Default temp dbspaces
# DUMP*:
# The following parameters control the type of diagnostics information which
# is preserved when an unanticipated error condition (assertion failure) occurs
# during database server operations.
# For DUMPSHMEM, DUMPGCORE, and DUMPCORE 1 means Yes, 0 means No.
DUMPDIR /tmp # Preserve diagnostics in this directory
DUMPSHMEM 1 # Dump a copy of shared memory
DUMPGCORE 0 # Dump a core image using 'gcore'
DUMPCORE 0 # Dump a core image (Warning: aborts XPS)
DUMPCNT 1 # Number of shared memory or gcore dumps for
# a single user's session
FILLFACTOR 90 # Fill factor for building indexes
# method for the database server to use when determining current time
USEOSTIME 0 # 0: use internal time (fast), 1: get time from OS (slow)
# Parallel Database Queries (pdq)
PDQPRIORITY 0 # Degree of parallelism: 0 => OFF, 1 => LOW,
# -2 => HIGH, max of 100.
MAX_PDQPRIORITY 100 # Maximum allowed pdqpriority
DS_ADM_POLICY FAIR # Decision-support admission and allocation policy
# FAIR: service queries based on scheduling level
# but preferring lower pdqpriority queries,
# STRICT: service queries based on scheduling level
# (highest before lowest) and FCFS within each level
DS_MAX_QUERIES # Maximum number of decision-support queries
DS_TOTAL_MEMORY # Decision-support memory (Kbytes)

# To leave Plan Monitoring inactive, set it to 0.
# Backup/Restore Variables
BAR_ACT_LOG /tmp/bar_act.log # File for errors, warnings, and messages
BAR_BOOT_DIR /usr/informix/etc

BAR_PROGRESS_FREQ 0 # ON-Bar progress output interval
ISM_DATA_POOL ISMData # Default volume pool for spaces
ISM_LOG_POOL ISMLogs # Default volume pool for logical log files
LOG_BACKUP_MODE MANUAL # When to back up logical log files:
# CONT - backup as soon as the file fills
# MANUAL - user must perform log backups
# NONE - do not back up logs and re-use them
# as soon as they fill. Use of NONE is not
# recommended as data will be lost if the
# database server must be restored.
