Checking Your Current Configuration
Using the INFO Command
You can use the NSKCOM INFO command to display static configuration information
and file attributes for swap files or processors. Example 3-7 shows the INFO command
display for all swap files for CPU 1 on a system running an H-series RVU.
In the example above, the user has issued the STOP command against the configured
swap file, $DATA.KERSWAP.CPU01B, to disable the swap file for future use.
Consequently, new processes swap to the configured swap file,
$SWAP.KERSWAP.CPU01A, and the default swap file, $SYSTEM.ZSYSSWAP.SWAP01.
Using the ENV Command
The ENV command displays various environmental information for NSKCOM,
including:
•
The NSKCOM version
•
Currently assumed swap file attributes
•
Current and default subvolume names
•
Whether logging is enabled and the LOG file name, if any
•
Processor page size (the number of bytes per memory page)
