EC Properties
This section describes the different properties that you can use to configure ECs.
- For Private Cloud and AWS, the properties are stored in the
values.yaml
file, where you define the systemProperties or in the EC Deployment web interface to configure ECs.
Aggregation Properties
You can set the properties listed in the Advanced tab of the Aggregation profile in your EC. This will override the values that were originally set in the profile, including the default values.
The following properties are applicable when using file storage for aggregation.
Property | Description |
---|---|
mz.aggregation.storage.maxneedssync | Default value: This property defines when updated aggregation sessions shall be moved from cache to the file system. When the number of cached aggregation sessions reaches this value, the sessions are written to disk. This property shall be set to a value lower than "Max Cached Sessions", configured in the Aggregation agent. If the property is set to a higher value, the used value will be "Max Cached Sessions" minus 1. For example, if "Max Cached Sessions" is "6000" and this property is set to "6500", the value "5999" will be used instead. For performance reasons, this property should be given a reasonably high value, but consider the risk of a server restart. If this happens, the cached data might be lost. |
mz.aggregation.storage.profile_session_cache | Default value: This property is used to speed up the start of workflows that run on the EC. Set the property to true to keep aggregation cache in memory for up to 10 minutes after a workflow has stopped. |
mz.aggregation.timeout.threads | Default value: This property is used to enable Multithreading in Aggregation workflows, that is, to use a thread pool for the timeout function block in the Aggregation agent. Use a value larger than 0, for example, 4 to use four threads in the thread pool. |
For more information about how to use these properties to tune the performance of the Aggregation agent, see Aggregation Agent (2.3).
EC Specific Properties
Property | Description |
---|---|
ec.webserver.port | Default value: This property specifies the listening port for the platform to determine the status of the EC. |
Couchbase Properties
Property | Description |
---|---|
mz.cb.statistics.flush.period.in.seconds | Default value: If you have enabled the log to file functionality in the Advanced tab of the Couchbase profile, you can determine how often in seconds you want to flush this file by modifying the value. |
Database Properties
Property | Description |
---|---|
max.cached.prepared.statements | Default value: If you want to change the number of preparedStatements that are cached between connections, you can use this property to specify a different number than the default. Note! If you are using SAP HANA as a database type in a Database profile, used by Database agents, this value has to be set to 0. |
connectionpool.strict.pool.size | Default value: false If you enable this property, the database pool enables the Blocking Queue implementation where there is a strict restriction to the maximum number of connections. Note! When the property is set to false, then the database connection pool will create additional temporary connections. When the pool is full, these connections are closed as soon as the workflow thread returns the connection to the pool. This property is general for all supported databases. It is enabled per each EC separately. If enabled the connection pool for the particular EC have a strict maximum limit. The maximum limit can be set in the Database profile agents "Properties tab" explained here: Database (2.3). |
connectionpool.wait.timeout.milliseconds | Default value: 5000 Note! This property can only be used if the connectionpool.strict.pool.size property is set to This property is used to configure the amount of time a thread should remain in the blocked queue until it tries for a new connection. If a connection is made available before this time, the thread's waiting time is interrupted. |
Diameter Properties
Property | Description |
---|---|
mz.diameter.tls.accept_all | Default value: If the property is set to false (default), the Diameter Stack agent does not accept any non-trusted certificates. If it is set to true, the Diameter Stack agent accepts any certificate. In either case, any unrecognized certificate will be logged in an entry in the System Log (in PEM format). |
mz.workflow.decoderqueue.max_threads | Default value: This property specifies the maximum number of threads used by the Diameter Stack agent for decoding messages. Setting a lower value than the default may enhance performance if the host machine has a low number of CPU cores and the active workflows are complex. On the other hand, the decoding may constitute a bottleneck when performing simple processing on a host machine with a high number of CPU cores. In this case, setting a higher value may provide better performance. |
Inter Workflow Properties
Property | Description |
---|---|
mz.iwf.max_size_block | Default value: By setting this property (in Bytes) on the EC that runs the Inter Workflow storage, it is possible to restrict memory consumption. If the agent wants to allocate more memory than the given property value during collection, the collection will abort instead of suffering a possible "out of memory". Note that the minimum value is 32000 bytes, and even if a lower value is configured, 32000 will be used. |
Table Lookup Service Properties
mz.inmemory_table.table_strategy | Default value: This property defines how shared tables are kept in memory. The possible values are:
|
mz.inmemory_table.index_strategy | Default value: This property defines how the index for shared tables are kept in memory. The possible values are:
|
mz.inmemory_table.fixed_width | Default value: This property defines if the varchar data fields are stored with a fixed or variable width. The possible values are:
|
Additional Properties
ec.backlog.dir | Default value: This property is applicable for ECs and determines whether you want events and error messages occurring when the contact is lost to be logged in a backlog or not. If the property is not present, events and messages will not be logged. The value of this property specifies where the backlog resides. |
ec.shutdown.time | Default value: This property specifies the maximum time (in milliseconds) the EC will wait before a real-time workflow stops after a shutdown has been initiated. This is to enable the workflow to stop all input and drain all UDRs in the workflow before shutting down. The wait time is initially set to 60 seconds. If this value is set to 0 all draining is ignored and the workflow will stop immediately. |
pico.bootstrapclass | Default value: This property specifies the bootstrap classes that are required by some components. |
pico.ec.do_graceful_shutdown | Default value: true This property determines the behavior of the mzsh command shutdown. When you have set the value of this property to |
pico.rcp.server.port | Default value: This property specifies the port that is used for EC to EC communication. If no port is set, a dynamic port will be used and the port number will change each time an EC is restarted. |
mz.use.drdateformat | Default value: The date syntax used in the APL functions Even though the syntax conforms to You can enable date format handling based on the |
mz.use.date.timezone | Default value: Setting this property to In most cases, the property should be set in the pico configuration of ECs . However, in case of audit processing, the property should also be set in the pico configuration of the Platform. Note! If the |
pico.type | Default value: "" This property specifies the type of pico instance used for the EC. You can only define the value EC. |
