Restrictions and Known Problems
The following is a summary of currently known restrictions and potential problems.



Restrictions, Know Problems and Cautions


VAXC2DECC.EXE shareable library is 
required

The Enterprise Capacity and Performance suite requires that the 
DEC C Libraries be installed. These libraries may not be present 
on some older VMS systems. If the following message is received 
during installation:

ECP-E-NEEDS  Sharable Library  VAXC2DECC.EXE required

Install the C/C++ Runtime Components kit.

Link warnings 
All link warnings on OpenVMS should be ignored.

Ignore ECP$DRIVER error messages
The execution of ECP$STARTUP will result in the installation of 
the ECP Collecter driver for the pseudo device cpa0:. The IO 
CONNECT of the driver may result in an informational error 
message. This message is innocuous and may be ignored.

PLAN COLLECT=/VERSION
On OpenVMS Alpha, the PLAN COLLECT=POLL/VERSION and 
PLAN COLLECT=SAMPLE /VERSION options do not currently 
work.

Caution when using /INTERVAL
The /INTERVAL qualifier does not enforce a minimum value. The 
Minimum value should be 60. Values lower than this are not 
recommended.
Computer Associates' TNG UNICENTER
 
V2.1.5 Data not supported
ECP Analyzer will not work with the PSPA$READ.EXE provided 
with CA TNG UNICENTER version 2.1.5. Older versions of 
PSPA$READ.EXE with older versions of data will work if the 
license is still valid.

Workload Analysis/Process 
Classification
All changes made to the process classifications and process 
transaction counts are immediately applied to the data structures 
and the Cancel pushbutton does not reverse changes. Exiting and 
re-entering this screen will cause edited transaction counts to be 
lost.

Unknown Disk Types from ECP/Collect
Disk types are not collected by ECP Collector for OpenVMS. They 
are picked up by .EVM. EVM will only collect disk types for disks 
which had I/O.


RAID Disk Configurations 
Currently none of the data sources provide accurate information 
on RAID disk set membership. In the case of host-based RAID 
sets, all disks should appear in the reduced file. In the case of 
controller-based RAID sets, the entire diskset may be represented 
as one disk. In either case, the user must correct the configuration 
prior to model build.


.EVM Required for OpenVMS models
ECP Reducer requires the .EVM data be present for data 
reduction. This is produced with the PLAN COLLECT=EVENT 
option. CPC files from PLAN COLLECT=POLL or =SAMPLE are 
not sufficient to build a model, although they are adequate for 
ECP Analyzer. BOTH collections need to be run when building a 
OpemVMS model.
