About configuring Grid for Infor Process Automation

Some Infor Process Automation configuration properties are set in the Infor Process Automation (IPA) section of Grid properties. For general information about how to access and use Grid, refer to the Grid administration section of the document Infor Landmark Technology Runtime Server Setup and Maintenance Guide which is available in the Landmark help.

General properties

The following properties are for specifying .jar files to be added to the classpath and data areas to be used for process execution.


Parameter	Description
grid.app.classpath	Copy any external .jar files, for example, JDBC, that you want to use in a process to this location: `$LACFGDIR/LPS/jars`
grid.app.dataareas	Specify the data area for the IPA to use. It is recommended that each IPA grid node be assigned to only one data area, so that each grid node can have its resources adjusted to the needs of that data area. Example: `grid.app.dataareas=PROD`

Connection pooling properties for Infor Lawson

Separate connection pools are maintained for each "data source", which is a combination of Infor Lawson host and Infor Lawson port. This means each "Infor Lawson server" has its own connection pool.

Enabling connection pooling can significantly improve the performance of processes with multiple nodes that connect to Infor Lawson applications. Within each connection pool, subpools are created for each user + Infor Lawson program, which prevents an unused connection for a user to be reused by a different user or a different Infor Lawson program.

Requests to borrow a connection from the pool will be honored as long as the subpool for the user + Infor Lawson program has not reached the limit of active connections (pfi.pooling.s3MaxActiveConnections).

If the limit is reached, pfi.pooling.s3MaxConnectionWaitSec determines if a failure happens immediately, a wait happens for a period of time then fails, or an indefinite wait happens.

When a connection is returned to the pool, if the limit for idle connections has been reached then the connection is closed, otherwise it goes to the pool. An "eviction" process can be configured (pfi.pooling.s3TimeBetweenEvictionRunsSec) which will scan for unused connections that can be removed. Any connection that has been in the pool for 30+ mins (currently not configurable) will be closed.

Validation of unused connections can be performed before the pool hands out a connection. If a connection is "invalid", it is removed and a new connection is created before being handed out by the pool.

Connection validation for Infor Lawson pooling properties

When connection validation is enabled, unused connections in the pool are first validated before being given out. An invalid connection will be closed and a new connection created before it is handed out.

Note:

The Infor Lawson server has a configuration option that automatically closes any idle connections. The default is 10 minutes. Care should be taken to configure this correctly in relation to the Infor Lawson connection pool setup.


Parameter	Description
pfi.pooling.s3UsePooledConnections	Enables or disables Infor Lawson connection pooling Default = false
pfi.pooling.s3MaxTotalConnections	Maximum number of active connections for ALL users + Infor Lawson programs. A negative number means no limit. Default = -1
pfi.pooling.s3MaxActiveConnections	Maximum number of active connections for a user + Infor Lawson program. A negative number means no limit. Default = 10
pfi.pooling.s3MaxIdleConnections	Max number of idle connections for a user + Infor Lawson program. A negative number means no limit. The pool will have at least this many connections for the user + Infor Lawson program. Note: Zero (0) means all returned connections are closed which results in no pooling. Default = 2
pfi.pooling.s3MaxConnectionWaitSec	Time (seconds) to wait for an available connection, if pool is full for the user + Infor Lawson program. Options are: 0 = immediate failure -1 = indefinite wait >0 = wait for specified time, then fail Default = 300
pfi.pooling.s3TimeBetweenEvictionRunsSec	Determines how often the eviction process is run. (It should be configured to run infrequently.) -1 turns off the eviction process. When enabled, connections idle for the configured duration are closed. Default = 900
pfi.pooling.s3EnableConnectionValidation	Enables or disables the verification of connections. Default = false
pfi.pooling.s3ValidationQuery	Defines a query used to verify that the S3 connection is still valid. Defaults to a lightweight query that can be used for verification. `/sso/SSOServlet?_action=PING&_updateSession=true`
pfi.pooling.s3ValidationTimeSec	Determines how often the validation is performed, instead of every time the connection is used. If 300 is specified, the connection validation is performed at least after 5 minutes when the connection is being used. This is specific to each connection. Default = 0 If the specified validation time is 0, validation occurs every time a connection is used.

Connection pooling properties for File Access using Amazon S3

The properties in this section needs to be added in configuration properties in the gen data area by the cloud administrators when setting up an Amazon S3 connection using the File Access configuration.


Parameter	Description
amazonS3.fileSizeLimit.`<tenant gen dataarea>`.`<dataarea>`	File size limit Sets up the single read file size limit per connection (in MB) Default = 500 MB
amazonS3.isMultiPartTransferEnabled.`<tenant gen dataarea>`.`<dataarea>`	Multi-part enabled States whether the users are able to transfer files in multiple parts. True/False, Default = false
amazonS3.connectionLimit.`<tenant gen dataarea>`.`<dataarea>`	Connection limit Specifies the number of connections allowed for Amazon S3 Default = 1
amazonS3.multiPartThreadsPerConnection.`<tenant gen dataarea>`.`<dataarea>`	Multi-part threads per connection Number of threads per connection for multi-part transfers for the data area Default = 4

Custom Activity node properties

The properties in this section apply only if you use the Custom Activity node.


Parameter	Description
pfi.customActivity.beans	Class names for .jar files needed for custom activities. List them in this property separated by commas or semicolons. IPA must be stopped and restarted in order for these activities to be available.
pfi.customActivity.beansToRunSeparate	It is a good idea to isolate custom adapters in a separate process to ensure that they do not interfere with IPA general operation. This true / false flag indicates that custom adapters will run in their own process, separate from IPA.
pfi.customActivity.beansToRunSeparateOptions	This parameter lets you specify your own runtime options for custom activities. These options are available only for custom activities that run in a separate process.
