New Features Technical Discussion
 DNS name resolution
 NT print management (SpoolSS)
 Member server
 Licensing
 Potpourri
Compaq Enterprise Technical
Symposium 2001
16
DNS Support
 DNS name resolution by clients supported as
of PW V6.0C and AS V7.3
 Client DNS name resolution required for
dynamic cluster load balancing
– See Advanced Server Administrators Guide
for more information on dynamic balancing
Compaq Enterprise Technical
Symposium 2001
17
Tech Tips: NETBIOS Name Resolution
 If Enabling Dynamic Alias Resolution…
– Remove static entries for cluster alias!
– NETBIOS names are resolved with LMHOSTS or
WINS before DNS
 Added ability for Advanced Server to use DNS for
name resolution
– Enabled via PWRK$CONFIG/Transports
– V6.1, V7.3
– DNS used as last resort
 After LMHOSTS, broadcast, WINS
Compaq Enterprise Technical
Symposium 2001
18
NT Print Management Support (V7.3)
 New optional functionality in V7.3
 NT style management of printer resources
– Specifically, added the SPOOLSS pipe
 Use NT Print Manager to manage OpenVMS
printer resources
– ADMIN CLI will have minimal print management
support
 Allows print drivers to be stored on Advanced
Server for downloading to the client
Compaq Enterprise Technical
Symposium 2001
19
Upgrading Existing Printers
 Existing Printers = Printer Shares defined on AS at time
NT Style Printing is enabled
 Automatically upgraded when choosing “Enable NT Style
Printing”
 Upgraded printers will have restricted manageability &
functionality
– Print Manager won’t work
– No drivers
 Upgraded printers will need to be deleted and re-added
via NT Print Manager to gain full management
functionality
Compaq Enterprise Technical
Symposium 2001
20
Adding New Printers
 “Add Printer” in Printers Folder on AS system
 Select Port will show available Execution Queues
on OpenVMS
 Specify Printer Name
 Provide Printer Driver
– From CD-ROM, or other location
– Stored on Advanced Server for downloading to
clients
Compaq Enterprise Technical
Symposium 2001
21
What about generic queues?
 OpenVMS generic queues point to multiple
execution queues (one to many relationship)
 Prior to NT Style Printing, it was possible to share
generic queues to the network
 NT Print Manager will display Execution Queues
as Printer Ports
– Generic Queues will not show up as a ‘port’
– In other words, they can’t be shared with NT Style
management as they were previously
Compaq Enterprise Technical
Symposium 2001
22
Printer Pooling
 Problem: How do I retain the one-to-many
functionality of generic queues?
 Solution: Printer Pooling
– Enable “Printer Pooling” in the Add Printer applet
– Select the Printers to be shared
– Let Advanced Server handle the one-to-many
relationship!!!
Compaq Enterprise Technical
Symposium 2001
23
Printer Pooling (2)
 Select Printer Pooling
 Select all the execution
queues that will be used
by this Printer
 Continue with the Wizard
Compaq Enterprise Technical
Symposium 2001
24
Restrictions
 Upgraded Printers don’t have full capabilities
 Once you choose NT Style Printing, it is difficult
to go back
– Will require restore from backup
 Limited support from the ADMIN CLI
Compaq Enterprise Technical
Symposium 2001
25
CAUTION!
 Performance Issue with NT Print Management
 More than 100 printers – not recommended at this
time
– Larger systems can support more
– No firm benchmarks available
 Improvements, to be delivered in a future release:
– TBD
Compaq Enterprise Technical
Symposium 2001
26
Member Server Role (V7.3, V6.1)
 Adding support for the member server role
– Previously, PW/AS servers only supported PDC
& BDC roles
 Behavior when using member server role:
– Server does not participate in SAM replication
– Domain NETLogon requests not processed
– User authentication for connecting clients passed
through to a domain controller
 Allows PW/AS to participate in a pure Windows
2000 domain
Compaq Enterprise Technical
Symposium 2001
27
Member Server Local vs Global SAM
Databases
 Member Servers have a SAM!!!
– But, its not the domain SAM, it is a local SAM
– Known only to that member server
 Local SAM:
– Represented by user or group name
 Administrator, Administrators
– Local groups only, global groups have no meaning
 Global SAM:
– Represented by user or group name, but, qualified with
domain name
 \\DOMAIN1\Domain Admins
 Reference KB article: Q126436
Compaq Enterprise Technical
Symposium 2001
28
More local vs global SAM
 Access to resources: Local SAM checked first
– Be careful of same names in Local and Global
SAMs
 Recommend not using Local SAM database
– Or, be sure you know why you are using Local
SAM and why.
Compaq Enterprise Technical
Symposium 2001
29
ADMIN and Local/Global SAMs
 ADMIN defaults to managing the Global SAM
 To manage a local SAM:
– Use \\ServerName instead of a domain name.
– For Example:
LOGIN/DOMAIN=\\memberserver
SET ADMINISTRATION/DOMAIN=\\memberserver
COMMAND/DOMAIN=\\memberserver
 ADMIN prompt becomes \\memserv\\memserv>
– When logged in or Set ADMIN to local database
Compaq Enterprise Technical
Symposium 2001
30
Member Server and ADMIN
 Not Allowed on Member Servers:
SET COMPUTER/ACCOUNT_SYNCHRONIZE
SET COMPUTER/ROLE=xxx
SHOW COMPUTER (except to specific comp)
ADD COMPUTER
REMOVE COMPUTER
ADD|SHOW GROUP/GLOBAL
SHOW GROUPS/GLOBAL
ADD|COPY|MODIFY USER/PRIMARY_GROUP=xxx
ADD|REMOVE|SHOW TRUST
Compaq Enterprise Technical
Symposium 2001
31
Member Server and ADMIN (2)
 ADMIN behavior on LOCAL SAM
 ADD/COPY/MODIFY/REMOVE/SHOW GROUP commands
will only manage local groups.
– Global Groups may exist but, they are ignored on
Member Servers
 ADD USER adds to the "Users" local group.
– Also added to Domain Users global group but not
seen by users
 SHOW USER will only show memberships in local groups.
– Won't show primary group
 ADD/COPY/MODIFY USER will only manage
memberships in local groups.
Enterprise Technical
32
– Primary group isCompaq
not supported.
Symposium 2001
Member Server and ADMIN (3)
 DEBUG SET /FLAGS=BYPASS_MEMSRVCHKS
– Bypasses Member Server specific checks on
USER and GROUP commands
– Allows you to really see what’s in the Local
database
 Not familiar with ADMIN DEBUG?
– $ ADMIN DEBUG HELP
Compaq Enterprise Technical
Symposium 2001
33
Member Server Tech Tip #1 (V7.3 only)
 Recommend joining a domain by specifying
username/password of administrator account
– Alternative is to add server to domain prior to
running config
– Some sites may not have access to administrator
account
 If you don’t join domain via specifing
username/password, only local accounts can
manage the local server
 Not a problem in V6.1
Compaq Enterprise Technical
Symposium 2001
34
Member Server Tech Tip #2
 Problem:
– Same username in global domain and local member
server user database
– Attempt to connect to member server resources from
global account
– Member Server attempts to validate access against local
account – Access fails
 Solution:
– If local accounts match global accounts, user “Connect As”
and specify domain with user name:
 \\domain\user
Compaq Enterprise Technical
Symposium 2001
35
Member Server Tech Tip #3
 Explicit Hostmaps are lost on role change to/from
member server
 When changing roles, the hostmap database (LSA) is
recreated.
– Previously existing hostmaps lost
 Recommend using ADMIN SHO HOSTMAP before role
change and ADMIN ADD HOSTMAP after role change to
restore.
– Do not attempt to use old LSA database
– Old LSA has old ServerObject – Not good for new config
Compaq Enterprise Technical
Symposium 2001
36
Member Server Role: Upgrading from
PATHWORKS V5
 Issue:
– How do I upgrade from V5 to V6 Member
Server?
– V5 to V6 Upgrade Utility only allows upgrade to
Backup Domain controller
 Solution:
– Upgrade to Backup Domain Controller, and then
use PWRK$CONFIG to change role to Member
Server
Compaq Enterprise Technical
Symposium 2001
37
License policy
 All client access to PW V6 & AS V7 must be licensed
 All client access requires a “Client-Access” license
– PWLMXXXCA06.00 - PW-V6.0
– PWLMXXXCA07.02 - AS-V7.2
– PWLMXXXCA07.03 - AS-V7.3, PW-V6.1
 May be used as a client-based or server-based license
– Per seat (replaces FPA)
– Per server (replaces FPS)
Compaq Enterprise Technical
Symposium 2001
38
V73/V6.1 Potpourri:
 Registry Incompatibilities
 MOD USER /PWDEXP
 SAM corruption
 Dir Cache
 Pulse Message/Inactive Daemon
 SHO USERS has new fields
 Disable License Ping
 RestrictAnonymous
 Manual Synchronization
Compaq Enterprise Technical
Symposium 2001
39
Tech Tip: OpenVMS Registry
Incompatibilities
 OpenVMS V7.3 & OpenVMS V7.2-1 registries incompatible
– Must upgrade OpenVMS on all cluster nodes which will run
the registry
– Registry must be running on all Advanced Server nodes
 All cluster nodes which will run Advanced Server must
upgrade OpenVMS simultaneously
– Registries on OpenVMS V7.2-1/OpenVMS V7.3 will not work
together in a cluster
 OpenVMS V7.2-2 is compatible with OpenVMS V7.3
– Problem doesn’t exist with OpenVMS V7.2-2/V7.3
Compaq Enterprise Technical
Symposium 2001
40
MOD USER /PWDEXP (V7.2A – ECO3/4)
$ ADMIN MODIFY USER user-name/PASSWO="passwd"
$ ADMIN MODIFY USER user-name/PASSWO="passwd"/FLAGS=PWDEXP
 These commands do not expire the password
– Workaround: Issue separate expire command
$ ADMIN MODIFY USER user-name /PASSWO="passwd"
$ ADMIN MODIFY USER user-name /FLAGS=PWDEXP
 Fixed in V7.3
– Was never a problem in V6
Compaq Enterprise Technical
Symposium 2001
41
SAM Corruption
 V7.3, V7.2A-ECO4, V6.0C-ECO2 fix SAM
corruption
 No need for modified PWRK$SHUTDOWN
– The “interlock shutdown with NetLogon” fix
– Only use PWRK$SHUTDOWN provided with kit
 Uncontrolled shutdowns can cause corruption
 Report reproducible SAM corruption to Customer
Support Center
Compaq Enterprise Technical
Symposium 2001
42
Directory Cache
 Clients sees empty or partial directories
 Fixed in V7.3, V7.2A-ECO4, V6.0C-ECO2
 Make sure XQP patches are current
– Should always do this
 If you still see this – update to latest ECO, notify
Customer Support
Compaq Enterprise Technical
Symposium 2001
43
SAM Replication Pulse Message Inactive Daemon
 Problem: PW/AS cluster is BDC, PDC needed to
resolve alias to “active” daemon node of cluster
– If alias resolved to “inactive” daemon node,
replication pulse messages would go to wrong
node.
– Partial synchs of SAM didn’t occur
– WAN only (LAN uses broadcasts)
 Resolution: If “inactive” daemon gets a pulse, it
passes it on to the “active daemon”
– Active Daemon will respond to Pulse Message
– In V6.0C-ECO2, V6.1, V7.3
Compaq Enterprise Technical
Symposium 2001
44
SHOW USER – new fields
 ADMIN SHOW USER /FULL, /ACCOUNTS or
/PROFILE now includes:
– Last Log On: 08/23/00 05:07 PM
– Password Last Set: 06/30/00 11:03 AM
– Password Changeable: 06/30/00 11:03 AM
– Password Expires: 09/11/00 11:03 AM
 In V7.3, V6.1
Compaq Enterprise Technical
Symposium 2001
45
Disable Client License Ping
 If using only server based licensing, define
PWRK$LR_DISABLE_CLIENT_PING, to bypass
client license check on client request
– When clients connect, PW/AS first attempts to
validate a license on the client
– If not using any client based licenses, you might
as well skip that step.
 See Advanced Server for OpenVMS Guide to
Configuring Licenses for more information
 V7.3 & V6.1

47
Domains with RestrictAnonymous set
 PW/AS cannot join a domain if the PDC has
RestrictAnonymous set
 Check this registry location:
Key:
Value Name:
Data Type:
Value:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA
RestrictAnonymous
REG_DWORD
1
 Workaround: Set value to 0 while joining domain
– Can be reset to non-zero value immediately after
joining the domain.
Compaq Enterprise Technical
Symposium 2001
48
More RestrictAnonymous Issues
 Secure Channels can not be created to Win2K servers
with RestrictAnonymous=2
– Trusts, External authentication, are affected
 ADMIN LOGON, ADMIN SET PASSWORD do work.
 Per MS KB articles value of 2 is for pure Win2K configs
only – no down level clients or servers
 KB articles:

Manual Synchronization Failures
 From Server Manager/Synchronize with PDC,
always choose the cluster Alias, not individual
nodes.
 Since SP5, choosing a node results in machine
account secret passwords out of synch
– Can no longer establish secure channel
 Recovery: Select the cluster alias and then
“Synch With Primary Domain Controller”

 Share lock used a parent/child mechanism, will be
simple locking
2. Threadlocks instead of VMS Locks
 Threadlocks are 12 times faster
 Use threadlocks for non-shared resources
 When a resource becomes shared, promote to
VMS lock
Compaq Enterprise Technical
Symposium 2001
54
Performance Improvements
Examples
 Focus on reducing BUFIO
– Improve FID and directory cache hit rates
– Improve file lookup algorithms
 Directory cache is now write through
 Fix cross-cluster invalidation of the directory
cache
– Improved local node too!
 Increase FID cache capacity from 8K to 16K files
– Increases hit rate
Compaq Enterprise Technical
Symposium 2001
55
File Lookup description
 File Lookup: Any attempt to access a file header
– Optimized thru the FID cache
 Lookups can be by name or by FID (File ID)
 The flow is as follows:
–
–
–
–
First try to ‘hit’ the fid cache
If alias (short) name, convert to FID, try to hit again.
Do a wildcard lookup against the XQP to get the FID.
Do a XQP lookup to get the file header contents, and
store the results in the FID cache.
Compaq Enterprise Technical
Symposium 2001
56
File Lookup optimizations in V7.3A
 If we have a filename but not a FID, lookup in the
directory cache to get the FID.
– Very likely to succeed, unless its a short name.
 Alias short name processing improved.
 Fixed several problems which could result in
unnecessary ‘misses’ in the FID cache
 Results: 20-25% higher hit-rates in the FID cache,
much less Buffered I/O’s against the XQP
Compaq Enterprise Technical
Symposium 2001
57
Performance Improvements
1
Observations
 Directory Enumeration of 5000-file directory
– FID cache sized for 8K files
– Elapse time went from 52 seconds to 13 seconds
– I/Os went from 21,000 to 300 (100% hit rate on
caches)
 UNZIPing large .ZIP file (2500 files)
– Elapse time went from 70 minutes to 6 minutes
1
Laboratory observations, actual results will vary
Compaq Enterprise Technical
Symposium 2001
58
Performance Improvements
1
Observations
 Cross-cluster activity
– Create/delete files in same directory from multiple
cluster nodes
– Before – 50% hit rate single node, 13% cross
cluster
– After – 87% hit rate single node, 80% cross
cluster
1
Laboratory observations, actual results will vary
Compaq Enterprise Technical
Symposium 2001
59
Opportunistic Locking (OpLocks)
 3 types of Locks
– Exclusive (Level 1)
 Client opens file for exclusive access, free to do arbitrary
buffering and caching on the client, free to write
 Server breaks the OpLock when another client requests access
 Can break to Level II or None
– Level II
 Multiple readers, no writers
 Client doesn’t request level II, server converts Exclusive or
Batch to level II
 Must be broken to none to write.
Compaq Enterprise Technical
Symposium 2001
60
Opportunistic Locking (OpLocks)
 3 types of locks (continued)
– Batch
 Client keeps file open on the server, even though
its closed from the client application perspective
– Typical of batch file processing: Open file, read a line,
close file, process line, etc until done
 Similar to Exclusive, server will break to Level II or
none
