The SAS OnDemand Decision Engine does not start after a rule deployment. When this problem occurs, the following error is displayed in the SAS log:

The same error condition can occur for the SAS OnDemand Scoring Engine server on the mainframe.

One situation where this SAS error occurs is when a string longer than 65534 characters is assigned to the RPT_HASFIRED_VARNAMES_INIT macro variable. The problem can happen when a rule calls one of the following macros many times:  

• %hasAnyAuthorizationRuleFired
• %hasAnyQueueRuleFired
• %hasAnyVariableRuleFired

Each of these macros calls the %hasRuleFired macro once for each rule of the respective rule types: Authorization, Queue, or Variable.

The macro variable RPT_HASFIRED_VARNAMES_INIT is first set to empty. When the %hasRuleFired macro is called, two values for each rule ID are appended to the variable. The length of the RPT_HASFIRED_VARNAMES_INIT macro variable can grow to exceed the maximum length when many rules are defined on the system and when the %hasAnyrule-typeRuleFired macro is called multiple times in a rule.

The SAS log section below shows the value of the RPT_HASFIRED_VARNAMES_INIT variable after 16 rule IDs in the multi-organizational node A are appended to it:

To work around this issue, you can adjust the rule code to call %hasAnyAuthorizationRuleFired, the %hasAnyQueueRuleFired, or %hasAnyVariableRuleFired a single time at the beginning of the rule code and to store that result to a local variable. Then, throughout the rest of the rule code, you can check the local variable value instead of calling the macro again.

Example:

Note: This issue can occur also in earlier releases of SAS^® Fraud Management.
