Table 7 Sybase ASE attributes (continued)
DescriptionSybase ASE Attributes
Name of the Sybase ASE instance set during installation or configuration of the ASE.
This uniquely identifies an ASE instance
ASE_SERVER
Sends an e-mail message to the specified e-mail address when packages fail. This e-mail
is generated only when packages fail, and not when a package is halted by the operator.
ALERT_MAIL ID
To send this e-mail message to multiple recipients, a group e-mail ID must be created
and specified for this parameter. When an e-mail ID is not specified for this parameter,
the script does not send out this e-mail
ASE Login with system administrator capabilitySALOGIN
ASE Password for Login with system administrator capability.SAPASSWD
NOTE: Along with other package attributes, the ASE password is also stored in the
Cluster Database. If users are not restricted access based on their roles, this password
can be viewed by unauthorized users using the cmviewcl command. It is highly
recommended to grant access to users based only on their roles in managing the cluster
and packages. See “Configuring Access Roles” (page 67) in this chapter for more
details on configuring Role Based Access (RBA).
Path of the script to start ASE instance.ASE_RUNSCRIPT
This parameter is used to specify the instance shutdown mode only when a shutdown
is initiated by the user and not due to a failure of a service. This parameter can take
USER_SHUTDOWN_MODE
values "wait" or "nowait". If "wait" is specified, the instance is shutdown using the wait
option, which will be a clean shutdown. If "nowait" is specified, the instance is shutdown
using the nowait option. The default value is "wait".
The interval of time, in seconds, which this script should wait between checks to ensure
of the Sybase database running. Default value is 30 seconds.
MONITOR_INTERVAL
The interval of time, in seconds, to wait for Sybase abort to complete before killing the
Sybase processes defined in MONITOR_PROCESSES. The TIME_OUT variable is used
TIME_OUT
to protect against a worst case scenario where a hung database prevents the halt script
from completing, therefore preventing the standby node from starting the database. The
value of TIME_OUT must be less than the time-out set in the package configuration file.
TIME_OUT variable has no effect on package failover times. Default value is 30 seconds.
The maximum amount of time in seconds to wait for an ASE to complete recovery before
determining that the server has failed to start up. This value must be set to allow enough
time for all the databases to recover and come online.
RECOVERY_TIMEOUT
The names of all processes that must be executing to ensure this instance is up and
running.
MONITOR_PROCESSES
Maintenance flag will enable or disable the maintenance mode for the Sybase package.
By default this is set to "yes". In order to disable this feature, MAINTENANCE_FLAG
MAINTENANCE_FLAG
should be set to "no". If the Sybase ASE instance needs to be maintained, a file
$TKIT_DIR/sybase.debug needs to be touched. During this maintenance period
the Sybase ASE instance's monitoring is paused. Even if the ASE instance is brought
down, the package will not be failed over to the standby node. To continue monitoring
and come back from the maintenance mode, the sybase.debug file should be removed.
It is the user's responsibility to ensure that the ASE instance is running properly after the
maintenance phase.
• Module Script (tkit_module.sh)
This script contains a list of internally used variables and functions that support the starting
and stopping of an Sybase ASE database instance. This script is called by the Master Control
Script to perform the following:
