HTTP Session Cache (httpSessionCache)

Controls how HTTP sessions are persisted using JCache.

NameTypeDefaultDescription

libraryRef

A reference to top level library element (string).

Identifies JCache provider files.

uri

A file, directory or url.

Vendor specific JCache configuration URI, which is passed to the JCache provider when obtaining the CacheManager.

Performance

scheduleInvalidationFirstHour

int
Min: 0

Max: 23

Enable this option to reduce the number of cache updates required to remove invalidated HTTP sessions. Specify an hour of the day when there is the least activity. When this option is disabled, the invalidator process runs every few minutes to remove invalidated HTTP sessions.

scheduleInvalidationSecondHour

int
Min: 0

Max: 23

Enable this option to reduce the number of cache updates required to remove invalidated HTTP sessions. Specify an hour of the day when there is the least activity. When this option is disabled, the invalidator process runs every few minutes to remove invalidated HTTP sessions.

writeContents

  • ALL_SESSION_ATTRIBUTES

  • GET_AND_SET_ATTRIBUTES

  • ONLY_SET_ATTRIBUTES

ONLY_SET_ATTRIBUTES

Specifies which session data is written to the persistent store.
ALL_SESSION_ATTRIBUTES
All attributes are written to the persistent store regardless of whether getAttribute or setAttribute are invoked.
GET_AND_SET_ATTRIBUTES
Attributes for which getAttribute or setAttribute is invoked are written to the persistent store. This can be useful for applications that use getAttribute to obtain and mutate attribute values without using setAttribute to explicitly request that they be written to the persistent store.
ONLY_SET_ATTRIBUTES
Only attributes for which setAttribute is invoked are written to the persistent store.

writeFrequency

  • END_OF_SERVLET_SERVICE

  • MANUAL_UPDATE

  • TIME_BASED_WRITE

END_OF_SERVLET_SERVICE

Specifies when session data is written to the persistent store.
END_OF_SERVLET_SERVICE
Session data is written to the persistent store after the servlet completes execution.
MANUAL_UPDATE
Session data is written to the persistent store upon programmatic sync of the IBMSession object.
TIME_BASED_WRITE
Session data is written to the persistent store according to the write interval.

writeInterval

A period of time with second precision

2m

Specifies how often to write session data to the persistent store. This value is used when a time-based write frequency is enabled. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.

library

Identifies JCache provider files.

NameTypeDefaultDescription

apiTypeVisibility

string

spec,ibm-api,api,stable

description

string

Description of shared library for administrators

filesetRef

List of references to top level fileset elements (comma-separated string).

Id of referenced Fileset

name

string

Name of shared library for administrators

library > file

Id of referenced File

NameTypeDefaultDescription

id

string

A unique configuration ID.

name

Path to a file

Fully qualified filename

library > fileset

NameTypeDefaultDescription

caseSensitive

boolean

true

Boolean to indicate whether or not the search should be case sensitive (default: true).

dir

Path to a directory

${server.config.dir}

The base directory to search for files.

excludes

string

The comma or space separated list of file name patterns to exclude from the search results, by default no files are excluded.

id

string

A unique configuration ID.

includes

string

*

The comma or space separated list of file name patterns to include in the search results (default: *).

scanInterval

A period of time with millisecond precision

0

Scanning interval to check the fileset for changes as a long with a time unit suffix h-hour, m-minute, s-second, ms-millisecond (e.g. 2ms or 5s). Disabled (scanInterval=0) by default. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), seconds (s), or milliseconds (ms). For example, specify 500 milliseconds as 500ms. You can include multiple values in a single entry. For example, 1s500ms is equivalent to 1.5 seconds.
