PAC and SOR Environment Variables

All enterprise server instances that are part of a PAC need to have the following environment variable set:

ES_PAC=pacname

Each SOR within a PAC needs a specific environment variable set:

ES_SCALE_OUT_REPOS_n=sorName=sorType,connectionDetails##[TMP#][models]

where:

n

This is the SOR number and can be a value 1 to 9.

sorName

This is the name of the SOR and must not contain spaces.

In the context of using Redis, the sorName is used to retrieve the Redis master from Redis.

sorType

This is the type of data store being used and can be:

• redis
• redis_TLS
• coherence [6]

Use redis_TLS for TLS enabled connections to a Redis data store. See Redis Requirements and Configuration as a Scale-Out Repository for more information.

connectionDetails

For Redis this is the host name and port number of the scale out repository, in the form host:port. For example, localhost:6379. You can specify multiple connections by using a comma as a delimiter between each connection.

For Oracle Coherence the connection string is limited to 1024 characters and takes the form: [6]

[userid@][configfile][,property=[value]]…

where:

userid

This is the optional user to use when Oracle Coherence security is enabled.

configfile

This is the name, location, URL of the cache configuration file. If this is omitted it defaults to mfes-cache-config.xml.

property

This is the name of a Java property to set to the value or is clear if value is unspecified.

value

This is the value of the Java property to set.

The configuration used by the Enterprise Server clients should match the server configuration. So where for a Redis you might have:

ES_SCALE_OUT_REPOS_1=MySOR=redis,127.0.0.1:6379##TMP#

For Oracle Coherence you might have:

ES_SCALE_OUT_REPOS_1=MySOR=coherence,mfes-cache-config.xml,coherence.cluster=MyPAC_cluster,mfescache.wka.MyPAC_cluster=127.0.0.1:7574##TMP#

If you are using the default mfes-cache-config.xml filename you can omit its name and just specify the properties. For example:

ES_SCALE_OUT_REPOS_1=MySOR=coherence,,coherence.cluster=MyPAC_cluster,mfescache.wka.MyPAC_cluster=127.0.0.1##TMP#

Note: There are two adjacent comma characters where the configuration file name is missing.

The configuration file mfescache.cfg is used to specify options when Enterprise Server is starting the Java Virtual Machine (JVM). This file can be modified to specify properties in addition to the connection string properties, if specified in both, then the connection string property will override the configuration file value.

TMP

Indicates that this is a PSOR that stores active resources.

Note: You must specify exactly one PSOR for each enterprise server instance within a PAC and each enterprise server instance in the PAC must use the same PSOR.

models

Take the form:

=ResourceType=model[:model][#ResourceType=model[:model]]

where:

#

Delimits the set of models for a model type.

ResourceType

The resource type can be Temporary Storage (TS) or Transient Data (TD). Permitted values are TS and TD.

model

Specified as a string between 0-16 bytes long. TD names can only be four characters long. TS names can be up to 16 characters long. The string names support the use of the following wildcards:

*

Matches any string of characters.

+

Matches any one character.

Note: Trailing + wildcards are used to pad missing characters appropriate for the resource type. For example, if you are specifying a model for a TD resource type and only specify a single letter "A" then it is treated as "A+++".

:

Delimits between each model.

x'hex string'

A hexadecimal prefix can be specified in a SOR model by enclosing the hex string in quotes and preceding it with an x, for example, x'ABAB' or x'AABBCC'.

You can use 2B as a generic matching character, for example, x'AA2BAA' would match queues that begin with x'AAAAAA', x'AABBAA', and x'AACCAA' and so on.
