Server Configuration Parameters
| Name | Type | Default | Range | Description |
|---|---|---|---|---|
| acl.default.jobs.leader | string | VIEW,EXISTS,CHOWN | Default ACL for FlowTracer jobs assigned to the leader role. | |
| alerts.max | integer | 50 | [5--1000] | Maximum number of alerts. If more alerts are created, the oldest with the lowest level is archived. |
| allowcoredump | boolean | 0 | 0,1 | If nonzero, request the vovserver to dump core even if it was started from a
shell where limitcoredumpsize was zero. |
| allowForeignJobsOnUserTaskers | boolean | 0 | 0,1 | When set to 1, allows foreign users to submit jobs that run on a non-root tasker that is owned by a different user. When set to 0, foreign user-submitted jobs will not be scheduled on a non-root tasker. |
| allowUidForSecurityFile | integer | 0 | [0---2147483647] | Additional UID that can own the security.tcl file |
| alm.enable | boolean | 0 | 0/1 | Enable Altair Licensing. |
| autoForgetFailed | time spec | 2 days | [5m,infinity] | If the autoForget bit is set on a job, the job will be
forgotten automatically upon failure after the specified time. |
| autoForgetOthers | time spec | 2 days | [5m,infinity] | If the autoForget bit is set on a job, the job will be
forgotten automatically if it is not scheduled after the specified time. |
| autoForgetRemoveLogs | boolean | 0 | 0/1 | Try to remove the log files associated with auto-forgotten jobs. |
| autoForgetValid | time spec | 1 hour | [5m,infinity] | If the autoForget bit is set on a job, the job will be
forgotten automatically upon successful termination after the specified time. |
| autoLogout | time spec | 4 hours | [10m,infinity] | The period of inactivity after which the system automatically logs a user out of the browser interface. The minimum value for this parameter is 10 minutes. |
| autoRescheduleCount | integer | 4 | 0-10 | Specifies the maximum number of reschedule attempts per job. |
| autoRescheduleOnNewHost | boolean | 1 | 0/1 | Controls whether auto-rescheduling will avoid the same host (default) or just the tasker, allowing the job to run on a different tasker on the same host. Does not apply to auto-rescheduling based on exit status (see exit-status docs). |
| autoRescheduleThreshold | time spec | 0s | 0s-60s | This parameter deals with jobs that fail quickly. If the failure time is less or equal to the specified value, the job is automatically resubmitted at high priority, with the name of the failing host as a negated resource, so that the job will be placed on a different host (or tasker, configurable) for the next run. If the autoRescheduleThreshold is 0, automatic resubmission is disabled. A maximum of 4 auto-reschedules are permitted by default. This maximum can be controlled via the autoRescheduleCount parameter. Host/tasker behavior can be controlled via the autoRescheduleOnNewHost parameter. Does not apply to auto-rescheduling based on exit status (see exit-status docs). |
| autostop.timeout | 60s | This parameter provides a timeout for the execution of all scripts installed in
the SWD/autostop directory. The autostop function is called
automatically upon shutdown of the vovserver and all scripts
have up to the timeout to executed and exit. This time period is provided to allow
autostop scripts to communicate with the vovserver before
exiting, while protecting against a problematic script that fails to exit. Once the
timeout has been reached, the vovserver continues with its exit
procedure, and any autostop scripts that have opened a connection to the vovserver will likely fail. Default can be specified in
policy.tcl. Example: This parameter can also be set using the VTK API. Example:
|
||

| disablefileaccess | boolean | 0 |
If this parameter is greater than 0 (zero), the server will not access
any file that is not under $VOVDIR or $VNCSWD.
By 'access' we mean any operation on the file like stat(), open(), access().
This is a protection to
prevent a possible server freeze if
it tries to access files on an dead NFS server.
If this parameter is greater than 1 (one), then not only the server
disables access to files, but also the CGI clients that could possibly
show file information will disable such functionality.

in the resources.tcl file. A negative value of this parameter
is interpreted as "unlimited", |
| resMapToolDefault | integer | -1 (unlimited) | This parameter sets the default value for the resource map "Tool:toolname" for
a new tool. This resource map limits concurrent number of jobs using the tool. For
each individual tool, you can control the value of the map with a
vtk_resourcemap_set Tool:toolname number statement in the
resources.tcl file. A negative value of this parameter is
interpreted as "unlimited". |
|
| resMapUserDefault | integer | 50 | -1 (unlimited) | This parameter sets the default value for the resource map "User:username" for
a new user. This resource map limits the maximum number of jobs that the user can
run at the same time. For each individual user, you can control the value of the map
with a vtk_resourcemap_set User:username number statement in the

| sched.megapoll.threshold | integer | 100 | [5--10000000] | Threshold that defines how many clients are needed to declare that we are in a 'mega-poll' situation. |
| sched.taskerstats.enable | boolean | 0 | 0/1 | Enable scheduler statistics for taskers (used in unusedhw.cgi). |
| schedMaxEffort | integer | 20 | 5 90 | If the scheduler becomes expensive, i.e. if it takes more than 0.02 seconds to dispatch jobs, the vovserver adaptively skips some scheduling cycle to give time to the clients to interact with the vovserver. In this way, the scheduler effectively changes from a pure event-driven behavior to a cycle-based behavior. The cycle is controlled by the schedMaxEffort variable, which sets the ratio between the effort spent in the scheduler and the effort spend elsewhere. Example: If the schedMaxEffort is 20 (meaning 20% of time should be spent in the scheduler) and the scheduler time is 0.1s, then the scheduler will be called no more frequently than once every 0.5 seconds (0.1*100/20=0.5). |

| timeTolerance | time spec | 0 | [0,600] | Control the time tolerance of the server. The default value of 0 may be too strict for some networks. You will usually need to have ntp running to synchronize the clocks to use zero, but this is the best practice. Values up to about 3 seconds will not impose much performance penalty. |
