UMP, MCC, etc.) and data providers (e.g.,
MDBcells, wvcell, EventCell , etc.)
- Master Knowledge Base (MKB) contains the list of
all UKB and is responsible for zone management
as defined in ukrule.xms

DIA Setup Cleanup
- Review NSM r11.0 “DIA Tips and Troubleshooting”
document (available from SupportConnect) for
description of cleanup procedures
- DNA config directory include some key files. If any
of these files are deleted, it will prevent the DNA
cells from functioning correctly. For example if
skf12aes.dia file is deleted, it will require DNA cells
to be re-registered. So, only delete files listed in
the above document

Ingres user ID creation
In this example the “ateam” user ID was created with
full privileges. Command must be executed with
Ingres install user ID. In this case, NSM r11 was
installed from administrator user ID and the current
login ID is administrator as well

Ingres Startup
I manually started Ingres using
ingstart command.
Now Agent Technology is unable
to update MDB.
Why?
CA Confidential – Covered by NDA
Development Buddy Summit 2006
Copyright ©2006 CA. All rights reserved. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
WorldView Severity Propagation
Service
- Severity Propagation is dependent on Ingres
service for Ingres MDB
- Agent Technology is dependent on Severity
propagation registration
- If Ingres was started by ingstart command without
using –service option, Ingres service will not start
and this will prevent Severity Propagation from
starting
- Agent Technology will continue to wait for Severity
propagation registration
CA Confidential – Covered by NDA
Development Buddy Summit 2006
Copyright ©2006 CA. All rights reserved. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
Resolution
- Use ingstart –service option to start the Ingres
service as well
- If the Severity Propagation service is not started,
then start the service after starting Ingres Service

Installing from a Remote Session
If I want to install Unicenter
NSM from a Remote session
what considerations do I have
to keep in mind?
CA Confidential – Covered by NDA
Development Buddy Summit 2006
Copyright ©2006 CA. All rights reserved. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
Installing from a Unicenter Remote
Control Session
- You can not install Unicenter NSM from a
Unicenter Remote Control session if the host on
which you are installing is a Unicenter Remote
Control "managed host“
- This is because Unicenter Remote Control
"managed hosts“ use the CA Message Queuing
Service (CAM) and the install process shuts this
down during NSM install

Installing from Terminal Services
Session
- Installing from a mapped drive while in a Terminal
Services session on Windows 2000 is not
supported
- If installing on Windows 2000, install from a local
logon session or use the full universal naming
convention (UNC) path instead of a mapped drive
- This is due to a Microsoft bug. Review Microsoft
MSDN Knowledge Base article Q255582 for more
information.

Missing AIS Catalog
I have installed MDB on a
dedicated server with just
WorldView Manager but the AIS
local catalog is missing. Why?
CA Confidential – Covered by NDA
Development Buddy Summit 2006
Copyright ©2006 CA. All rights reserved. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
Missing AIS Catalog
- You must select at least one provider for the local
catalog to be created.
- If no providers are selected, the install process
determines that there is no requirement for a local
catalog.

Copyright ©2006 CA. All rights reserved. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
MCC Considerations
- If you install MCC without any providers, it will
create an AIS catalog but there will be no DNA
cells available
- As a result, MCC will not launch correctly.

PathSize
NSM install process will compute the
estimated size of the System Path
Entry based on the components
selected.
If this exceeds the maximum size, the
install process will not continue. What
options are available when multiple
products are installed?
CA Confidential – Covered by NDA
Development Buddy Summit 2006
Copyright ©2006 CA. All rights reserved. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
System Path Length
- Install process verifies the system path length will
not exceed 1024 bytes once the path is updated to
include the selected NSM r11 components
- If the length is likely to exceed the maximum
allowed, the install process will insist on
shortening the length or revising list of selected
components.

Multiple Products Install
- If Multiple Products are installed on the same server, path
length is likely to exceed 1024 bytes.
- If USD, DSM and NSM components are installed on the same
server, it will exceed the path length
- Options include:
- Shortening directory path name. Default NSM location is
- \Program Files\CA\Shared Components\CCS\WVEM
- Reduce number of components selected
- See “Path Length Considerations for Unicenter NSM r11.x”
document on Implementation Best Practices page for more
details and a tool for estimating path length

System Path Entry
- If you are uninstalling NSM, it is important to take a backup
of Path entry.
- path >mypath_backup.txt
- Unicenter NSM includes the CA Dylan Socket Adapter, which
adds a directory to the system PATH similar to
"C:\PROGRA~1\CA\SHARED~1\Dylan\bin."
- If any PATH entries are appended after this entry, when the
Dylan uninstall runs it will be unable to remove its PATH
entry. Intermittently, it may drop non-NSM entries, which
may result in some Windows Path entries being dropped as
well.
- This is an InstallShield issue

Conclusion
- 2495 events per second for local node MRA processing with
exception of Forward, Alert or command
- On average, 220 events per second can be forwarded from
each node without any significant delay
- Message storm of 50,000 events caused no significant delay
- 250,000 events storm is handled with latency of approx 74
seconds.
- 500,000 message storm is handled with latency of approx 2
mins on the last event

MDB Performance
Considerations
Performance Considerations
- Given adequate CPUs, memory, and disks, a dedicated
server is not required for installing Microsoft SQL Server
- Network latency between the application and a separate SQL
server may, in fact, degrade application performance
- It is best practice to always run SQL Server on the same box
as a mid-tier manager (e.g., Desktop Management Domain
manager should run on the same box as its MDB, and a midtier NSM local Core/MDB will often be faster)
- For the enterprise tier you may wish to run the MDB on a
dedicated SQL Server box – depending on the number of
enterprise components and the peak load

Manage Memory – see Notes
- Set Reserve Physical Memory for SQL server and
specify an amount. For a 4GB box we suggest
reserving at least 2GB (monitor memory usage to
determine if more memory can be reserved for SQL)

Manage Memory – see Notes
- Set minimum memory for SQL 2005 – on a 4GB box
we suggest reserving at least 2GB (monitor memory
usage to determine if more memory can be reserved
for SQL)

Performance Considerations
- Store MDB data and log directories on separate disk drives
for improved performance (keeping logs on a separate disk
can be a significant tuning benefit)
- The same applies to TEMPDB (TEMPDB on a separate disk
can be a significant tuning benefit)
- SQL data on striped disks is a major tuning benefit – if you
have limited drives available and must chose between
separate log/data disks or one striped drive, the striped drive
is usually best option – the more drives in a stripe set the
better (see notes)
- RAID 0 or RAID 10 offer the best performance – RAID 5 is
not generally the best performance option

TEMPDB
TEMPDB
- SQL Server uses the tempdb database as a scratch area for
MDB temporary tables, sorting, subqueries, ...
- TEMPDB should be on its own drive away from other DBs
whenever possible (default is SQL install disk)
- Increase the size of the TEMPDB database based on available
disk space and expected usage
- SQL Server adjusts the size incrementally over time, but
each adjustment causes a performance hit
- You may need to set the original size of the TEMPDB
database files to a reasonable size to avoid constant growth

Logging Considerations
Logging Considerations
- Install SQL Server on a disk with sufficient
available space – this is the default log location
- SQL Server allows transaction log files to exist on
multiple devices - this improves logging system
performance by allowing it to write to multiple
disks
- MDB Transaction Log automatically grows by 10%
and its growth is unrestricted
- Monitor log space – growth can occur even with
auto shrink

Logging Considerations
- In some situations the Transaction Log may become very
large, leading to the following situations:
- Run out of space
- Transactions may fail and may start to roll back
- Transactions may take a long time to complete
- When that happens, shrink it with DBCC SHRINKFILE: DBCC
SHRINKFILE(mdb_log, TRUNCATEONLY)
- For recovery purposes, immediately execute BACKUP
DATABASE
- IMPORTANT: shrinking the transaction log every day may
impact the performance of your database!
