This chapter explains how to use the ISM Resource Management Setup panels to specify the global CMCC management options for the ISM program. Pertinent information is in the following sections:
The options on the ISM Resource Management Setup panels apply to all routers that ISM manages. You can override the global setup options by defining router-specific CMCC options. For more information, see the "Specifying Administration Options for a CMCC Using the Standard Interface" section .
To enable ISM to monitor status and performance statistics for the CMCCs it discovers, use the ISM Resource Management Setup panel (Figure 6-3). CMCC management is disabled by default in ISM setup when ISM is first initialized.
 |
Note You must have ISM enable authority to enable CMCC monitoring or to modify other ISM rules. |
To enable ISM to monitor CMCCs, complete the following steps:
The ISM Administration menu panel (Figure 6-2) is displayed.
Step 2 Press Enter. The ISM Resource Management Setup—First Panel (Figure 6-3) is displayed.
Step 3 In the CMCC Management option, type Y in the Update column. YES appears in the Update column beside the CMCC Management option.
ISM uses the CPU Utilization and Free Memory thresholds that you enable on the ISM Resource Management Setup—Third Panel to determine the acceptable performance levels for discovered CMCCs on all routers. When these thresholds are exceeded, ISM issues a PERF alert if alert generation is enabled.
To enable CMCC alert generation for performance and memory thresholds and CMCC recovery, complete the following steps:
Step 2 In the CMCC Perf/Memory option, under Generic Alert Generation, type Yes.
Step 3 In the ISM CMCC Recovery option, type Yes.
To enable default CMCC monitoring thresholds for all routers, complete the following steps:
Step 2 To specify the maximum allowable CPU utilization percentage, type a value in the CPU Utilization option.
ISM issues a PERF alert for the CMCC when the CPU utilization exceeds the specified percentage.
ISM issues a generic alert in NetView's NPDA hardware monitor application if the CMCC Perf/Memory alert option on the ISM Management Rules Setup panel is enabled.
Step 3 To specify the minimum allowable percentage of free memory, type a value in the Free Memory option.
ISM issues a PERF alert for the CMCC when the free memory percentage is below the specified percentage.
ISM issues a generic alert in NetView's NPDA hardware monitor application if the CMCC Perf/Memory alert option on the ISM Management Rules Setup panel is enabled.
To enable channel interface monitoring, complete the following steps:
Step 2 In the Channel option, type Y.
If you have not initialized ISM for the first time and want to change the CMCC history database ID, or if you want to change the number of records in the database for new resources, complete the following steps:
The default record counts allow for approximately 24 hours before the database record will wrap for a resource.
Step 2 When you have completed specifying the options, press PF4 (UPDATE).

To view the channels that are on a specific router, position the cursor on the Channel option and press Enter. The channels that are known are displayed. Figure 6-18 shows sample output for router CWBCO1, a router with multiple CMCCs.
The Administration option appears on the CMCC Detail Display panel (Figure 6-10) if the operator is authorized to make changes. Position the cursor on the Administration option and press Enter. The ISM CMCC Administration panel (Figure 6-19) is displayed.
To override the established global thresholds for a particular router's CMCCs, specify individual thresholds on a per-router basis using the ISM CMCC Administration panel. To enable or disable CMCC monitoring and data archiving for a specific router, complete the following steps:
The notation C= with the specified percentage is displayed in the Overrides field. ISM will issue a PERF alert for the CMCCs on the selected router when the CPU utilization exceeds the specified percentage.
Step 2 To specify the minimum allowable percentage of free memory for the CMCCs on the selected router, enter a value (1% to 99%) in the Memory Threshold option.
The notation M= with the percentage that you specified is displayed in the Overrides field. ISM will issue a PERF alert for the CMCCs on the selected router when the free memory percentage is below the specified percentage.
Step 3 To enable or disable archiving of CMCC data, enter Yes or No in the Archive option.
Step 4 To enable or disable CMCC monitoring for the selected router, enter Yes or No in the Monitor Mode option.
Step 5 To remove history and performance records from the VSAM database for a specific router, enter Yes in the Delete history and performance records field.
Step 6 Press PF4 to save your changes.
After you have enabled CMCC management for the routers, you can use one of the following procedures to monitor the status for discovered CMCCs on all routers:
There are several ways to monitor the status of channel interfaces for routers. You can monitor the channel interface status either for all routers from the ISM main menu panel using the INT option (for a specific type of interface), or summarized with all other resources (for all interface types) from the ISM Status Summary panel. You can also monitor channels for a specific router by listing the CMCCs, selecting a router, and displaying that router's channel interfaces.
To monitor channel interfaces, on the ISM main menu (Figure 6-1), position the cursor on the Type field on the INT line, enter C, and press Enter. The Interfaces Type panel for channels (Figure 6-20) is displayed for all resources.
To display CMCC status for a specific router, tab to the resource and press PF12. The Cisco Mainframe Channel Connections panel (Figure 6-9) is displayed.
The CMCC hardware and software versions are displayed on several ISM panels:
The first dotted-decimal number is the hardware version, and the second-dotted decimal number is the software version. In the following example, 4.3 is the hardware version and 22.19 is the software version:
CIP 4.3 22.19
While there are many ways to access ISM's Router Command Interface, some ISM applications provide direct access to the command interface, and list the commands specific to the router currently being managed. When you use the CMCC Management application panels in ISM, you can access panels that provide router commands specific to managing CMCCs.
If a router supports the RUNCMD, you can use the CMCC and Channel Show Commands panel to run router show commands. To do so, complete the following steps:
Step 2 Position the cursor on Show Commands and press Enter. The CMCC and Channel Show Commands panel (Figure 6-21) is displayed, including the router control name and channel.
Step 3 To run a command, type the number that corresponds to the show command that you want to execute at the ISM command prompt, and press Enter.
To get command help from the router, type the number that corresponds to the show command followed by a ?, and press Enter.
You can access the Cisco Mainframe Channel Connections page from the ISM main menu or the ISM Status Summary page. To access the Cisco Mainframe Channel Connections page, complete the following steps:
