IBM 000-8697 User Manual

Utilities

Use the -u option to print a profile of user activity. The output described in
this paragraph is provided for each user process.

At a minimum, two user processes always appear in -u output: tbinit always
occupies the first entry and tbundo always occupies the second entry. If you
have configured OnLine for additional page cleaners (specified as

CLEANERS

in the configuration file), each page-cleaner daemon, tbpgcl, is listed as well.

You can interpret output from this option as follows:

address

is the shared-memory address of the user process (in the user
table). Compare this address with the addresses displayed in
the -s output (latches), the -b, -B, and -X output (buffers), and
the -k output (locks) to learn what resources this process is
holding or waiting for.

flags

position 1 indicate if the process is waiting for a resource:
