General System Properties

General System Properties

General system properties determine
Data Integration Hub
behavior, such as authentication mode and document store location.
The following table describes general system properties:
System Property
Description
dih.automap.instances.parameter.precision
The precision of the publication instance parameters
DXPublicationInstanceId
,
DXPublicationInstanceDates
, and
DXPublicationInstanceDatesSQL
in subscription mapping. By default 90,000.
Precision is calculated at 60 characters for each publication. For aggregated subscriptions that consume more than 1,500 publications increase the precision accordingly.
dih.events.api.max.results
The maximum number of events the
events API
returns. The number includes the parent and the child events.
Default is 2000.
For more information about Events API, see
Developer Guide
.
dih.event.details.input.file.hide
Hides the content of the file of any File Event in the Event Details page.
You can set the following values:
  • True. The file content is not displayed in the Event Details page.
  • False. The file content is displayed in the Event Details page.
Default is False.
dih.file.publication.aggregation.delay
For file publication, the wait time in minutes before the publication file events are aggregated. The events are aggregated and triggered after this delay period. The wait time is applicable to all the file events that exist when aggregation is evaluated.
Not applicable for publications with the scheduling option
When the file is ready to be published
.
dih.filetransfer.allpatterns.wait.timeout
For file transfer publications, time in minutes to wait from the time when the oldest event was created until all the files in the publication arrive. If all files do not arrive within the defined time,
Data Integration Hub
discards the File events that are related to the Publication event and changes the status of the Publication event to Error. By default 10 minutes.
dih.filetransfer.publication.aggregation.delay
For file transfer publications, time in seconds to wait until releasing Delayed file events for processing. By default 30 seconds.
Do not set a value that is lower than 30 seconds.
Not applicable for publications with the scheduling option
When the file is ready to be published
.
dih.filetransfer.publication.poll.interval
For file transfer publications, time interval in minutes for
Data Integration Hub
to scan remote sources. If this property does not exist or is empty,
Data Integration Hub
scans remote sources every five minutes. The value of this property must be from 3 to 30 minutes.
dih.flatfile.publication.aggregation.batch.delay
For single-pattern flat file publications, time in seconds to wait from the first event until publication file events are aggregated. The value of this property must be from 0 to 86400 seconds.
dih.flatfile.publication.evaluation.interval
For single-pattern flat file publications, time interval in seconds for aggregation rule evaluation. The value of this property must be one of the following values: 10, 20, 30.
dih.help.hosted
Connects to hosted help. When set to False,
Data Integration Hub
connects to bundled help.
dih.hadoop.column.delimiter
Column delimiter in files that
Data Integration Hub
writes to and reads from a Hadoop publication repository.
If you change the value of this property you must open all publications that write to a topic with a Hadoop publication repository and all subscriptions that read from topic with a Hadoop publication repository in the publication or the subscription wizard, correspondingly, and run the wizard for each publication and subscription.
dih.hadoop.service.url
URL for the service that manages write and read activity for the
Data Integration Hub
Hadoop publication repository.
dih.home.hide.at.startup
Determines the display of the Operation Console Home page when users log in to
Data Integration Hub
. You can set the following values:
  • False. The Home page shows the
    Data Integration Hub
    Overview diagram.
  • True. The Home page shows a Welcome page.
Default is False.
dih.realtime.time.window
For real-time publications, defines the buffer time that
Data Integration Hub
waits before the written publications are published.
The default value is 1, which has no impact on the publication time.
Change the buffer time when you have multiple tables in a topic and you want to ensure that the records for all tables are included in the same publication.
dih.splash.message
Define a splash message to display to all users. You can announce features, write a message on downtime or alerts, and so on. The maximum character length is 200.
dih.staging.lifetime.maximum
Maximum number of days to store published data in the publication repository. After the lifetime period for a publication instance expires, the publication repository cleanup process deletes the data from the publication repository, regardless of whether the data was consumed or not.
Default is 90 days.
The value of
dih.staging.lifetime.maximum
must be larger than the value of
dx.retention.period.default.days
and larger than the values of the publication data retention period of any of the existing topics.
dih.subscription.skip.staging.check
Based on the instance ID, a check is run on the publication repository for the number of rows published to the mapped tables of the topic.
You can set the following values:
  • True. A check is not run on the publication repository for the number of rows published to the mapped tables of the topic.
  • False. A check is run on the publication repository for the number of rows published to the mapped tables of the topic.
Default is False.
  • The dih.subscription.skip.staging.check system property is applicable for the following subscription types:
    • Automatic Relational Subscription
    • Automatic Flat File Subscription
    • Automatic Pass-Through Subscription
  • The dih.subscription.skip.staging.check system property is not applicable if the Join tables are mapped in Field Mapping.
dx.authentication.groups
Names of the Informatica domain security groups to synchronize. If you do not specify a value, the Informatica domain security domain synchronizes only the administrator user account that you define when you install
Data Integration Hub
. You can define multiple security groups separated by semicolons.
You must enter the authentication group name and domain name in the following format:
<group>@<InformaticaSecurityDomain>[;<group>@<InformaticaSecurityDomain>]*
For example: B2B@Native
dx.authentication.mode
Active authentication mode.
dx.retention.period.default.days
Default value for the number of days to store published data in the publication repository after the published data is consumed. After the data retention period for a publication instance expires, the publication repository cleanup process deletes the published data set from the publication repository.
The default value is seven days. The
Data Integration Hub
operator can change the data retention period in the
Data Retention
page of the
Topic
wizard.
The value of
dx.retention.period.default.days
must be smaller than the value of
dih.staging.lifetime.maximum
.
dx.retention.period.running.time
The time of day on which to run the publication repository cleanup. When the cleanup starts,
Data Integration Hub
checks the retention period for all published data sets in the publication repository and deletes published data sets for which the retention period expired before the cleanup started.
Default is 23:00.
