System configuration [VC 21.3 GEN]

Indexing configuration

The indexing configuration contains the parameters that relate to search and indexing.

• Where Vidispine can reach Solr or ZooKeeper.

• When to commit or soft commit.

• The Solr query request parameters.

• The default field settings.

This configuration replaces the configuration properties listed under Search and indexing.

Example

Full text indexing could be disabled for all fields, unless explicitly specified for a field, using:

<IndexingConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <solrPath>http://localhost:8088/solr</solrPath>
  <fieldDefault>
    <name>*</name>
    <fullText>false</fullText>
  </fieldDefault>
</IndexingConfigurationDocument>

Metrics configuration

See StatsD on how to configure how metrics are sent to StatsD. The configuration resource is described at Metrics settings.

FTP pool configuration

By default jobs that need to read or write to an FTP server will establish, use and end separate connections to the server. By configuring a FTP connection pool you can change so that the jobs share and reuse FTP connections. This can reduce the time it takes to transfer files over high latency connections.

For example, to create a connection pool with the default settings:

PUT /configuration/ftp-pool
Content-Type: application/xml

<FtpPoolConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <pool/>
<FtpPoolConfigurationDocument/>

If no pool is specified then pooling will be disabled. Unless overridden, the pool will be unbounded, and connections will expire after 1 minute. That is, the above configuration is identical to:

PUT /configuration/ftp-pool
Content-Type: application/xml

<FtpPoolConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <pool>
    <minSize>0</minSize>
    <maxSize>-1</maxSize>
    <evictionInterval>30000</evictionInterval>
    <minIdleTime>60000</minIdleTime>
  </pool>
</FtpPoolConfigurationDocument>

The FTP pool configuration resource is described at FTP pool configuration.

Database purging

Vidispine supports mechanisms for purging old information in database tables. Especially four tables can grow quite large without purging enabled.

Updated method for purging configuration

The preferred way of updating the database purging configuration is by create a DatabasePurgingConfigurationDocument, see Database purging configuration.

Change-log table

The change-log table holds information about data that should be sent to other sites. If multi-site is disabled (disableSiteCrunching), this table grows forever.

To enable purging of the table, two configuration properties are used: changeLogPurgingTime and changeLogForcePurgingTime. The first one controls deletion of entries that have been processed, the other one controls deletion of entries regardless of state.

Sensible values are 43200 and 86400, corresponding to one and two months, respectively.

Configuration can also be controlled via DatabasePurgingConfigurationDocument. For example:

<DatabasePurgingConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <changeLog>
    <age>43200</age>
    <forceAge>86400</forceAge>
  </changeLog>
</DatabasePurgingConfigurationDocument>

Audit trail table

The audit trail table contains all API requests, see Audit trails.

To enable purging of the table, two configuration properties are used: auditTrailPurgingTime and auditTrailPurgingDirectory. Both must be set in order for purging to take place.

When purging is enabled, entries that are older than auditTrailPurgingTime minutes will be removed and put in a file inside the auditTrailPurgingDirectory folder.

A sensible value is 43200 or higher, corresponding to one month.

Configuration can also be controlled via DatabasePurgingConfigurationDocument. For example:

<DatabasePurgingConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <auditTrail>
    <age>43200</age>
    <uri>s3://key:secret@archival-bucket/requests/</uri>
  </auditTrail>
</DatabasePurgingConfigurationDocument>

By setting the compress element in the configuration document, entries will be stored using gzip compression. The default value is true.

The entries are stored in batches. The number of entries per batch is controlled by the batch element in the configuration document. The default value is 10000 entries. If there are less than 10000 entries that fulfill the time criteria, the purging of the audit trail table will pause.

By setting the body element in the configuration document, entries will also include the request bodies and response codes. The default value is false.

The directory can be a full URI, such as a S3 or FTP location.

Job table

To enable purging of the table, two configuration properties are used: jobPurgingTime and jobPurgingDirectory. Both must be set in order for purging to take place.

When purging is enabled, entries that are older than jobPurgingTime minutes will be removed and put in a file inside the jobPurgingDirectory folder.

Configuration can also be controlled via DatabasePurgingConfigurationDocument. For example:

<DatabasePurgingConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <job>
    <age>43200</age>
    <uri>s3://key:secret@archival-bucket/job/</uri>
  </job>
</DatabasePurgingConfigurationDocument>

By setting the compress element in the configuration document, entries will be stored using gzip compression. The default value is true.

The directory can be a full URI, such as a S3 or FTP location.

Transfer log table

Configuration is controlled via DatabasePurgingConfigurationDocument. For example:

<DatabasePurgingConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <transferLog>
    <age>1440</age>
    <uri>s3://key:secret@archival-bucket/transfers/</uri>
  </transferLog>
</DatabasePurgingConfigurationDocument>

Both the age and uri element has to be set. Entries than represents a finished transfer older than age minutes are exported to the destination.

The forceAge element controls exports of non-finished transfers - transfers that have disappeared for some reason. The default value of forceAge is the value of the age element.

By setting the compress element in the configuration document, entries will be stored using gzip compression. The default value is true.

The entries are stored in batches. The number of entries per batch is controlled by the batch element in the configuration document. The default value is 10000 entries. If there are less than 10000 entries that fulfill the time criteria, the purging of the transfer log table will pause.

Default job priority

The default job priorities are configurable by type. For example, the following configuration document will make IMPORT jobs default to MEDIUM priority and EXPORT jobs default to HIGH priority:

<JobPriorityConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <job type="IMPORT">MEDIUM</job>
  <job type="EXPORT">HIGH</job>
</JobPriorityConfigurationDocument>

If no default priority has been specified for a given job type, the job will default to MEDIUM priority.

CORS configuration

Vidispine can be configured to emit Cross-Origin Resource Sharing (CORS) headers.

The CORS configuration is set using the CORS configuration resource. The configuration document consists of a number of entries, each of them are checked for CORS evaluation. If an entry condition matches the incoming request, the CORS headers set in the entry are outputted, and no other entries are matched. For example:

PUT /configuration/cors

<CORSConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <entry>
    <request/>
    <response>
      <allowOrigin>*</allowOrigin>
    </response>
  </entry>
</CORSConfigurationDocument>

The conditions in each entry can match HTTP method, the request path, the CORS origin, or any other header. For example:

<CORSConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <entry>
    <request>
      <pathRegex>API.*/item/.*</pathRegex>
      <headerRegex>
        <key>connection</key>
        <value>.*aliv.*</value>
      </headerRegex>
    </request>
    <response>
      <allowOrigin>*</allowOrigin>
      <allowMaxAge>86400</allowMaxAge>
    </response>
  </entry>
</CORSConfigurationDocument>

Semantics are as follows.

• Multiple methods can be set per entry. If one entry method matches the request method, the entry matches as far as for method. If no methods are set on the entry, the entry matches.

• Origins can be specified both exact or via regular expressions. If one entry origin matches the request origin, the entry matches as far as for origin. If no origins are set on the entry, the entry matches.

• Request paths can be specified via regular expressions. If one entry path matches the request path, the entry matches as far as for path. If no paths are set on the entry, the entry matches.

• Request headers can be specified via regular expressions. All specified headers for the entry must match the request. If the HTTP request does not contain a value for a specified header, the entry does not match. If the HTTP request contains multiple values for a specified header, it is sufficient that only one value matched the entry header condition.

When the entry matches, the entry may contain which origin that is allowed, the max age for the access, which methods that are allowed, which HTTP headers. The entry can also contain other, arbitrary, headers. If methods are not specified, the methods are automatically deduced from the API methods.

Configuration properties

Configuration properties are used in Vidispine to control system-wide parameters.

If set to true, Vidispine agent will be used to compute the hash of the files.

Default:

false

useVxaMimeType

If set to true, Vidispine agent will be used to detect the mime type of the files.

Default:

false

Deletion lock

autoRemoveExpiredDeletionLocks

It set to true, expired deletion locks on collections and items will be removed automatically

Since:	4.15
Default:	false

deletionLockCleanUpBatchSzie

Number of “to be removed” or “expired” deletion locks that will cleaned up in one batch.

Default:	100

System properties

System properties are set as argument to the JVM. See Setting JVM options.

The following properties are used in Vidispine:

com.vidispine.site

The site id prefix for the current site.

Default:

VX

com.vidispine.license.dir

The directory containing the Vidispine license or slave license file.

Default:

${com.sun.aas.instanceRoot}

com.vidispine.license.tmpdir

The directory where temporary license files may be stored.

Default:

${com.sun.aas.instanceRoot}

com.vidispine.credentials.dir

The directory containing credentials files such as the AwsCredentials.properties file used with Amazon S3 and Glacier.

Default:

${com.sun.aas.instanceRoot}

com.vidispine.log.dir

The directory containing the server log files.

Default:

${com.sun.aas.instanceRoot}/logs

vidispine.identifier.format

If full, output Long identifiers.

Default:

Normal, short identifiers.

com.vidispine.xml.prefix

Controls namespace prefix mapping of XML written by Vidispine that is _not_ part of API output, e.g. XML written to files. Comma-separated list of {namespace}={prefix} assignments. Namespaces without assignment get a ns# prefix.

Default:	Only ns# prefixes.
Example:	http://www.smpte-ra.org/schemas/2067-2/2016=cc

infi.sleep_after_start

The number of seconds to sleep after starting Infinispan, before VidiCore going on starting other services.

This should prevent “split-brain” issue during startup in some cases.

Default:

-1 (No delay)

com.vidispine.asyncpool.coresize

Controls the size of the internal async pool in VidiCore (New in 5.3.1.). It’s also available as a configuration property.

Default:

5

com.vidispine.service.quorum

The VidiCore background services (i.e. IndexCruncher, JobCruncher, etc.) would only be started/stopped if the quorum is reached. This is to prevent “non-clustered” services from being started on multiple nodes in a cluster with a “split-brain” issue.

The quorum value should be set to > N/2, where N is the total instance count in the cluster.

For Example: The quorum should be set to 2 for a two-node-cluster as well as a three-node-cluster.

(New in 5.3.5.).

Default:

1

Since 5.3, some system properties can be overridden by configuration properties. The properties that can be overridden are:

• com.vidispine.site

• vidispine.identifier.format

• com.vidispine.xml.prefix

Also in 5.3, is is possible to change the log levels of components using configuration properties. The configuration properties used for this is:

• loglevel. followed by the component name. (e.g. loglevel.com.vidispine.filemgmt.storagesupervisor)

It is now also possible to override the com.vidispine.service.quorum system property using a configuration property as above.

While it is possible to change these values on a system in production, it is adviced that changing these values are done on an idle system, as the update in a cluster is asynchronous.

Bulky metadata storage

By default, the values of bulky metadata are stored in the database. In a large system, this can occupy a large portion of the database. In version 5.3, there is the possibility to store bulky metadata on file system (or cloud storage).

To change the configuration the bulky metadata configuration resource is used. The configuration document contains two parameters, a base URI for where the bulky metadata should be stored, and an option to disable that storage. An explanation on how these to parameters interact follows below.

Transferring bulky metadata from database to file system

To move bulky metadata entries from database to the file system pointed out by the URI, use a configuration document like this:

PUT /configuration/bulkymetadata
Content-Type: application/xml

<BulkyMetadataConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <uri>file:///mnt/srv/bulkystorage/</uri>
</BulkyMetadataConfigurationDocument>

When this configuration is set, all bulky metadata is written to the file storage. Reading metadata is also done from file storage, but if the file storage does not contain the metadata, the database is read instead.

The path that is used to store the bulky metadata looks like this:

• Item id, with the id split in thousands

• Shape id, with the id split in thousands

• Key, channel, stream, and timecode, delimited by -.

In order to migrate all metadata to the storage, a reindex command is used:

PUT /reindex/bulkymetadata

When the reindex process has finished, all metadata is on the storage. This can be verified by retrieving the bulky metadata configuration, which also returns status information.

GET /configuration/bulkymetadata
Accept: application/xml

<BulkyMetadataConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <uri>file:///mnt/srv/bulkystorage/</uri>
  <status>
    <metadataInDatabase>0</metadataInDatabase>
    <metadataOnStorage>45033</metadataOnStorage>
    <storageStatus>OK</storageStatus>
  </status>
</BulkyMetadataConfigurationDocument>

Transferring bulky metadata from file system to database

To move bulky metadata entries back from the file system to database, use a configuration document like this:

PUT /configuration/bulkymetadata
Content-Type: application/xml

<BulkyMetadataConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <uri>file:///mnt/srv/bulkystorage/</uri>
  <storageDisabled>true</storageDisabled>
</BulkyMetadataConfigurationDocument>

Note the URI is still present, but the storageDisabled is set to true. It is vital that the URI remains set, and unchanged, as metadata will be read from the storage if it is not present in the database.

To migrate all metadata, use again:

PUT /reindex/bulkymetadata

GET /configuration/bulkymetadata
Accept: application/xml

<BulkyMetadataConfigurationDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <uri>file:///mnt/srv/bulkystorage/</uri>
  <storageDisabled>true</storageDisabled>
  <status>
    <metadataInDatabase>45033</metadataInDatabase>
    <metadataOnStorage>0</metadataOnStorage>
    <storageStatus>OK</storageStatus>
  </status>
</BulkyMetadataConfigurationDocument>

Once everything has been migrated, the URI can be removed from the configuration, if preferred.

Transferring bulky metadata from one storage to another

There are two ways of moving bulky metadata from one storage to another.

1. Move metadata from storage to database, ensure every metadata is moved, then move metadata to new storage.

2. Stop/pause Vidispine, copy or move files from the old storage to the new storage. Start Vidispine and change URI.

If the second option is chosen, tools like rsync or aws s3 sync can be used to do a first synchronization while the system is in use.

Important notes

Advanced configuration/tweaking

Methods in this section should only be used after recommendation by Vidispine Support.

SQL Query rewriting

SQL queries sent by Vidispine can be modified by creating a file sqltranslations.txt in the /etc/vidispine/ directory. The format of the file are pairs of lines, where the first line of each pair is a regular expression, and the second line of the pair is a replace pattern, e.g.:

(?i)^(select .*)$
/* comment inserted */ $1
(?i)^(delete .*)$
/* another comment inserted */ $1
