IST154I |
Indicates that expansion failed for
one of the fixed-length buffer pools in ECSA subpool 231. The error
code displayed in the message provides additional information. |
IST561I |
Indicates that SLOWPT has occurred
in one of the fixed-length buffer pools in ECSA subpool 231. - If this message occurs only occasionally, you might need to do
some tuning in this area.
- If the console is flooded with this message, you might have a
CSA problem.
|
IST562I |
Indicates that a storage request
has failed because of one of the following reasons: - CSALIMIT start option or MODIFY CSALIMIT is not specified and
total CSA plus ECSA allocations have reached 90% of the total CSA
plus ECSA defined in the system.
- CSALIMIT start option or MODIFY CSALIMIT is specified and total
CSA plus ECSA allocations have reached 75% of the total amount of
CSA plus ECSA defined in the system.
- CSALIMIT start option or MODIFY CSALIMIT is specified with the
,F command modifier and the total CSA plus ECSA VTAM usage has reached this value.
|
IST564I |
Indicates that a GETMAIN failed for
the CSA subpool specified in the message. The specified subpool might
be the sources of the CSA problem or the problem might be caused by
another CSA subpool that is affecting the subpool displayed in the
message. Further investigation into the contents of storage is required. |
IST1832I |
Indicates that the value coded on
the CSALIMIT start option or a MODIFY CSALIMIT command is less than
25 megabytes, which may be too small. This might result in IST562I
messages (only if the ,F command modifier is specified). Use the DISPLAY
BFRUSE command output to monitor CSA usage and modify the CSALIMIT
value if maximum CSA usage approaches the CSALIMIT value (this is
necessary only if the ,F command modifier is specified). |
IST1833I |
This message will be issued only
if the CSALIMIT start option or MODIFY CSALIMIT command is issued
without the ,F modifier. Issue a DISPLAY BFRUSE,SUMMARY=* command
and compare the MAXIMUM value in the first IST449I message to the
value in IST1667I. If the first value is close to 75% of the second
value, it means that VTAM is
using a large proportion of system CSA storage. If so, an analysis
of VTAM's storage use is indicated. If VTAM is
not a large user of system storage but message IST1831I
indicates close to only 25% of system CSA plus ECSA storage remains
available for use, allocation of additional CSA or ECSA storage, or
both, may be needed. A determination of which process is potentially
using an inordinate amount of CSA or ECSA storage, or both, may also
be needed. |
