Control of the Type of Data Received Through ISR

For AOM, PPO, and Network Error Warning System (NEWS) (a component of CA NetMaster NM for SNA), you can control data exchange though the use of AOMPROC, PPOPROC, and CNMPROC respectively. For NTS, control is through the region and class parameter settings that request the type of data that NTS is to collect.

Note: For more information about the interaction of NEWS and NTS with ISR, see the CA NetMaster NM for SNA Administration Guide.

However, in the case of AOM, PPO, and CA NetMaster NM for SNA, there are important parallels that provide a general understanding of ISR operation in these environments.

The following functionality is common to AOMPROC, PPOPROC, and CNMPROC:

• Each of the environments in which each of the procedures resides has an ISR capability. This capability exists irrespective of whether an actual procedure is running in the environment at any time.
• The ISR command controls the data exchange between the environments. Internal or programmatic control is possible in a procedure by operands on the &xxxCONT and &xxxDEL NCL statements.

  Note: For the purposes of this topic, xxx refers to PPO, AOM, and CNM.

• All the environments have an &xxxREAD, &xxxCONT, &xxxDEL, or &xxxREPL that can be used to assist with the reading and distribution of the data they receive.

  A procedure reads the data it receives, processes the input, then repeats the process. If no &xxxCONT, &xxxDEL or &xxxREPL statements are issued during processing then by definition an implied &xxxCONT is performed.

  Note: For more information about &xxxREAD, &xxxCONT, &xxxDEL, and &xxxREPL, see the Network Control Language Reference Guide.

• Delivery of data to other regions through ISR can be handled as follows:

  Implicit delivery

  No specific destination information is specified for the data.

  For example, if there are no ISR connections enabled, no ISR delivery takes place. However, if there are links enabled for outbound messages, then a copy of the data is sent over every link. Where &xxxCONT is used, the NCL return code and feedback information indicate the result of the request.

  Explicit delivery

  Specific destination operands are specified on the &xxxCONT and &xxxDEL statements. These operands are LINK, DOMAIN, and SSCPNAME.

  Note: Only one of these operands can be specified at any one time. Not all components support the use of all these operands. For example, if you want to send the data from AOMPROC to only one of your two remote regions, identify this region on the &AOMCONT statement.
