INITIATORS

SolveWare subject INITIATORS is designed to maximize initiator utilization by Control-M. It adjusts IOA resources to reflect the actual state of initiators at your site.

Solution Provided

SolveWare subject INITIATORS contains the Quantitative Resource Handling solution. This solution updates the IOA Conditions file and the Control-M Resources file according to events that affect initiator availability, such as a job start, or START, STOP, and SET commands.

Quantitative Resource Handling

This SolveWare solution uses Quantitative resources to track initiator availability. A Quantitative resource is created for each class monitored by Control-M and these resources are updated whenever changes to initiator availability are detected. If, for example, a job in Control-M is started in a specific class, Control-M does not submit the job unless the relevant Quantitative resource indicates that an initiator that serves the appropriate class is available.

Normally (that is, without this SolveWare solution), Quantitative resources can determine resource availability based only on values defined within the IOA environment. Changes to initiators that were manually started, manually stopped, manually halted, or to initiators serving a manually submitted job (that is, a job not submitted by Control-M) are not reflected in Quantitative resources.

The rules for this SolveWare solution monitor changes outside the IOA environment to initiators in the JES2 environment and adjust (that is, increase or decrease) relevant resource quantities accordingly.

Global variables that indicate initiator name, classes served by the initiator, counters and names of relevant Quantitative resources, are defined in rules INITFRST and INITCRT in this solution (see following sections). In multisystem configurations, CPU configuration is described using Global variables defined during SolveWare initialization by rule JES2GLBL in table INITSLV2. For more information, see SolveWare Initialization.

Rules Structure

The following tables describe the structures of the Quantitative Resource Handling solution rules.

Table 155 Initialize Environment, Start Monitoring Initiators Rule Structure

Item	Description
Title	Initialize Environment, Start Monitoring Initiators
Name	INITFRST
Table	INITJES2
Event	INITFRST
Event Description	This Event rule initializes SolveWare solution INITIATORS. Global variables defined by this rule are necessary for the implementation of other rules in this solution.
Basic Scheduling Parameters	Always schedule this rule.
Runtime Scheduling Parameters	No special considerations.
Global Variables	%%CTM_CLASS_index Class to be monitored by Control-M, indexed by a sequence number. For more information on this variable, see Customization in this table. %%CTM Character used by Control-M as a system identifier in a multisystem environment (AutoEdit variable %%$SIGN). %%ID_smfid Global variables are set by rule JES2GLBL in SolveWare subject STARTSYS. This rule determines the value for the %%ID_smfid variable for the current system and stores it in Global variable %%CTM. If the SMFID of the current system is SYS1 and %%$SIGN=A was specified in the Control-M installation on this machine, the following values are specified: %%ID_SYS1=A in rule JES2GLBL %%CTM=A in rule INITFRST %%INIT_NUMBER Total number of initiators in the system. %%INIT_NUMBER=15. %%PROC_index Internal indicator of the status of Quantitative resources for classes served by a specific initiator. Valid values are NO Quantitative resources relevant to the initiator are under construction. This value is specified at the beginning of the rule before variables relevant to the initiator have been reset. %%PROC_1=NO YES Quantitative resources relevant to the initiator reflect real initiator state. This value is specified when the variables relevant to this initiator have been reset . %%PROC_1=YES
Rule Logic	This rule issues command $DI in command-response mode to generate a list of all initiators in the system. Each line of the response (message $HASP605) describes one initiator. AutoEdit variable %%INIT_NUMBER is set according to the number of lines in the command-response. This rule also sets Global variables that are used by other rules in this solution.
Rule Actions	Clears the environment from the previous run of this SolveWare solution. Defines classes monitored by Control-M. Counts initiators in the system. Initiates the environment for the solution.
Activating the Rule	The rule is triggered immediately once it has been ordered.
Recommended Mode or Category	During the testing period, activate the rule in LOG mode. When you are satisfied with the results of the rule and the log messages are no longer necessary, change the mode of this rule to PROD. The SolveWare category for this rule is 3—the rule is provided as an example. Implementation of the rule requires some customization.
Customization	Adapt the rule by changing the Global Variable list to reflect the real environment. Ensure that the appropriate number of %%CTM_CLASS_index variables are specified to define the classes to be monitored at your site. To avoid conflict with variables set by previous usage of this SolveWare, a variable with an index of one more than the number of classes must be specified with the value %%$UNDEF. If classes A and B are monitored by Control-M, the following must be specified: %%CTM_CLASS_1=A, %%CTM_CLASS_2=B, %%CTM_CLASS_3=%%$UNDEF In multisystem configurations, this rule uses Global variables defined by rule JES2GLBL. For customization information about these variables, see SolveWare Initialization.

Table 156 Set Up Initiator Global Variables Rule Structure

Item	Description
Title	Set Up Initiator Global Variables
Name	INITCRT
Table	INITJES2
DO RULE	INITCRT
DO RULE Description	This rule sets values of Global variables referenced by other rules in this solution.
Basic Scheduling Parameters	Always schedule this rule.
Runtime Scheduling Parameters	No special considerations.
Global Variables	%%CLASS_class_T Total number of initiators in the system serving a specific class. %%CLASS_A_T=25. %%CLASS_class_O Total number of available initiators in the system (that is,inINACTIVE status) serving a specific class. For example: %%CLASS_A_O=15 %%PROC_index Internal indicator of the status of Quantitative resources for classes served by a specific initiator. Valid values are NO Quantitative resources relevant to the initiator are under construction. This value is specified at the beginning of the rule before variables relevant to the initiator have been reset. %%PROC_1=NO YES Quantitative resources relevant to the initiator reflect real initiator state. This value is specified when the variables relevant to this initiator have been reset. %%PROC_1=YES %%IN_PROCESS Internal indicator of the status of all Quantitative resources describing initiators. Valid values are YES Quantitative resources relevant to all initiators are under construction. NO Quantitative resources relevant to all initiators reflect actual initiator status. %%INIT_index Initiator name, indexed by sequence number. For example: %%INIT_1=1, %%INIT_10=A %%JOB_index JOB ID of the job being processed by each initiator, indexed by sequence number. If an initiator is inactive, the %%JOB_index variable for that initiator has a value of NONE. For example: %%JOB_1=NONE %%JOB_10=JOB01384 %%CLS_index List of classes served by a specific initiator, indexed by sequence number. If the first initiator serves classes A, B and I and the second initiator serves only class A, the following is specified: – %%CLS_1=ABI – %%CLS_2=A %%CLS_#_index Number of classes served by a specific initiator, indexed by sequence number. If the first initiator serves classes A, B and I and the second initiator serves only class A, the following is specified: – %%CLS_#_1=3 – %%CLS_#_2=1 %%STC_index STC number of a specific initiator, indexed by sequence number. The value of this variable for initiators that are unavailable (for example, initiators in HALTED or DRAINED status) is (NONE). – %%STC_1=(NONE) – %%STC_10=STC32261).
Rule Logic	This rule is triggered by other rules in this solution: At the start of processing. Whenever certain JES2 commands are detected. This rule defines a Quantitative resource for each class monitored by Control-M. This rule dynamically defines Global variables that describe Control-M classes and initiator status. These variables are used by other rules in this solution to update Quantitative resources according to the number of available initiators serving each class.
Rule Actions	Initializes Global AutoEdit variables that describe initiators serving monitored classes. Sets all %%PROC_index Global variables to NO to prevent other rules in the solution from interrupting processing of this rule. Sets Global variable %%IN_PROCESS to YES to prevent other rules in this solution from interrupting processing of this rule. Issues command $DI in command-response mode to generate a list of all initiators in the system. Each initiator is described by three lines of the response message ($HASP605). AutoEdit variables %%INIT_index, %%JOB_index, %%CLS_#_index, %%CLS_index, %%STC_index, %%CLASS_class_T and %%CLASS_class_O are set according to information extracted from this message. When all response message lines for an initiator have been analyzed, the corresponding %%PROC_index Global variable is set to YES to re-enable update of relevant Quantitative resources. Sets Global variable %%IN_PROCESS to NO to again allow other rules in this solution to update Quantitative resources and Global variables relevant to JES2 initiator status. Calls rule STRS to update Quantitative resources.
Activating the Rule	Once ordered, the rule remains active until deleted from Control-O.
Recommended Mode or Category	During the testing period, activate the rule in LOG mode. When you are satisfied with the results of the rule, change the mode to PROD to avoid log messages for the rule. The SolveWare category for this rule is 3—this rule is provided as an example. Implementation of the rule requires some customization.
Customization	The rule uses Global variables defined by rule INITFRST in this solution. For customization information, see Table 155.

Rule Logic	The quantity specified for an Quantitative resource must be four digits in length. This rule determines the number of digits in the quantity to be specified and adds the appropriate number of leading zeroes to the quantity in the DO RESOURCE statement before updating the Quantitative resource.
Rule Actions	Builds the name of the Quantitative resource to be updated. The value stored in Global variable %%CTM is added as a suffix to this resource name to ensure that the resource name is unique. Builds a 4-digit quantity for the Quantitative resource name from a received parameter. Performs a DO RESOURCE action.
Activating the Rule	Once ordered, the rule remains active until deleted from Control-O.
Recommended Mode or Category	During the testing period, activate the rule in LOG mode. When you are satisfied with the results of the rule, change the mode to PROD to avoid log messages for the rule.
