Valid values:

The default values are SDB/REALM.ACL

The path specified is relative to the run directory of each FioranoMQ profile.

DeletedThresholdPercent

A cache stores and manages the list of all the tables pertaining to group based information in the file-storage based ACL. After repeated modification of the ACL, old entries in the table are marked as deleted. This value provides a threshold percentage of deleted entries after which the Cache Compaction Process is started. At the end of the Cache Compaction Process the table will not have any deleted entries. Since cache compaction involves CPU intensive File Operations, this flag is to be used along with DeletedThresholdCount to ensure it is not invoked too often.

Valid values:

The default value of this parameter is 50. This indicates that if the ratio of deleted entries to total entries is equal to or greater than 0.5 then the Cache Compaction Process will be invoked.

The range of integer values in java that are considered valid by the DeletedThresholdPercent parameter are -2^32 to 2^32 -1.

All values less than or equal to zero provide the same result. All values greater than or equal to 100 provide the same result.

Example:

Use the example of the ratio of deleted entries/total entries in the table. If there a chance that many entries will be marked deleted often, a higher number should be entered as the parameter value.

DeletedThresholdCount

A cache stores and manages the list of all tables pertaining to group based information in the file-storage based ACL. After repeated modification of the ACL, old entries in the table are marked as deleted. This value provides a threshold count of deleted Entries for starting the Cache Compaction Process. At the end of the Cache CompactionProcess the table will not have any deleted entries. Since cache compaction involves CPU intensive File Operations, this flag is to be used along with DeletedThresholdPercent to ensure it is not invoked too often.

Valid values:

The default value of this parameter is 10.

The range of integer values in java that are considered valid by the DeletedThresholdCount parameter are -2^32 to 2^32 -1.

All values less than or equal to zero provide the same result.

Example:

Although the DeleteThresholdPercent provides a ratio based method of ensuring that the Cache Compaction Process does not occur too often, it does not provide an absolute lower limit of the number of deleted entries needed to trigger a Cache Compaction. It is best to choose a value that is high so as to enable triggering a Cache Compaction.

DbTableNamePrefix

The database table names are usually prefixed with a string that can be modified by the DbTableNamePrefix parameter.

Valid value:

The default value of the DbTableNamePrefix is #

Any String value is a valid parameter.

MaxPasswordLength

Each principal is allotted a password and the MaxPasswordLength parameter enables the  configuration of the maximum allowable password length.

Valid value:

The default value of the MaxWordLength is 50.

The range of integer values in java that are considered valid by the MaxPasswordLength parameter are -2^32 to 2^32 -1.

All values less than or equal to zero provide the same result.

MaxMemberCount

UserClassInetOrgPerson store the four object classes used to assign various attributes to any user information stored in an LDAP-provider. These objectClasses are used to assign almost any attributes of the user and are defined by default in the schema of the LDAP-provider. Please note that - When creating a new LDAP entry, you must always specify all of the object classes to which the new entry belongs. Because many directories do not support object class subclassing, you also should always include all of the superclasses of the entry.

DeletedThresholdPercent

A cache stores and manages the list of all tables pertaining to principal as well as all related information in the file-storage table. After repeated modification of the table, old entries in the table are marked as deleted. This value provides a threshold percentage of deleted entries after which the Cache Compaction Process is invoked. At the end of the Cache Compact Process the table will not have any deleted entries. Since cache compaction involves CPU intensive File Operations, this flag is to be used along with DeletedThresholdCount to ensure it is not invoked too often.

Valid value:

The default value of the DeletedThresholdPercent is 50.  This indicates that if the ratio of deleted entries to total entries is equal to or greater than 0.5 the Cache compaction process is invoked.

Note:

  • The range of integer values in java considered valid by the DeletedThresholdPercentage value are -2^32 to 2^32 -1.
  • All values less than or equal to zero provide the same result.
  • All values greater than or equal to 100 provide the same result.

Example:

Use an example ratio of deleted entries/total entries in the table. If there is good chance that many entries will be marked as deleted then it is best to choose a higher number.

DeletedThresholdCount

A cache stores and manages the list of all tables pertaining to the principal as well as all related information in the file-storage table. After repeated modification of the table, old entries in the table are marked as deleted. This value provides a threshold count of deleted entries for starting the Cache Compaction Process. At the end of the Cache Compact Process the table will not have any deleted entries. Since cache compaction involves CPU intensive File Operations, this flag is to be used along with DeletedThresholdPercent to ensure it is not invoked too often.

Valid value:

The default value of the DeletedThresholdCount is 10.

The range of integer values considered valid for the DeletedThresholdCount parameter in java are -2^32 to 2^32 -1.

All values less than or equal to zero provide the same result.

Example:

Although the DeleteThresholdPercent provides a ratio based method of ensuring that the Cache Compaction Process does not occur too often, it does not provide an absolute lower limit of the number of deleted entries needed to trigger a Cache Compaction. A value high enough to trigger a Cache Compaction should be chosen.

Valid value:

The default value of the DbTableNamePrefix is #.

Any String value is a valid parameter.

Example:

If  the database table is to be saved in its current state and the the current state is to be saved to be used in the future, modify the prefix to another relevant string and change it back to the original string when the saved state of the database table is to be used.
