Increasing Connector Worker Threads

By default each Directory Server and Active Directory connector uses four worker threads to apply changes. This value is increased in the Global Telco deployment to improve the connector performance, especially during idsync resync operations. The number of connector threads is stored in the configuration directory in the pswNumOutboundConnectorThreads attribute, present in the pswSunDirectoryGlobals and in the pswActiveDirectoryGlobals entries. Before manually editing the configuration, all Identity Synchronization for Windows consoles must be closed.

To find the pswSunDirectoryGlobals entry, the following command is used:

bash-2.05# ./ldapsearch -b "ou=identitysynchronization,ou=services, dc=gt,dc=com" 
-D "cn=Directory Manager" -w <omitted password\> "(&(objectclass=pswSunDirectoryGlobals)
(pswversion\>=0))"  pswNumOutboundConnectorThreads

dn: cn=136,ou=Sun,ou=Globals,cn=active[13],ou=GlobalConfig,ou=1.1, 
ou=IdentityS ynchronization,ou=Services,dc=gt,dc=com
pswNumOutboundConnectorThreads: 4

The entry that must be modified is:

cn=136,ou=Sun,ou=Globals,cn=active[13],ou=GlobalConfig,ou=1.1,
ou=IdentitySynchronization,ou=Services,dc=gt,dc=com.

To find the pswActiveDirectoryGlobals entry, the following command is used:

bash-2.05# ./ldapsearch -b "ou=identitysynchronization,ou=services, 
dc=gt,dc=com" -D "cn=Directory Manager" -w <omittied password\> 
"(&(objectclass=pswActiveDirectoryGlobals)(pswversion\>=0))"  
pswNumOutboundConnectorThreads dn: cn=110,ou=ActiveDirectory,ou=Globals,cn=active[13],
ou=GlobalConfig, ou=1.1, 
ou=IdentitySynchronization,ou=Services,dc=gt,dc=com
pswNumOutboundConnectorThreads: 4

      

The entry that must be modified is:

cn=110,ou=ActiveDirectory,ou=Globals, cn=active[13],ou=GlobalConfig,ou=1.1,
ou=IdentitySynchronization,ou=Services,dc=gt,dc=com.

These two entries are modified to increase the number of threads to a maximum of 20:

bash-2.05# ./ldapmodify -D "cn=Directory Manager" -w <omitted password\>
dn: cn=136,ou=Sun,ou=Globals,cn=active[13],ou=GlobalConfig,ou=1.1, 
ou=IdentitySynchronization,
ou=Services,dc=gt,dc=com
changetype: modify
replace: pswNumOutboundConnectorThreads
pswNumOutboundConnectorThreads: 20

modifying entry cn=136,ou=Sun,ou=Globals,cn=active[13],ou=GlobalConfig, ou=1.1,
ou=IdentitySynchronization,ou=Services,dc=gt,dc=com
dn: cn=110,ou=ActiveDirectory,ou=Globals,cn=active[13],ou=GlobalConfig, ou=1.1,
ou=IdentitySynchronization,ou=Services,dc=gt,dc=com
changetype: modify
replace: pswNumOutboundConnectorThreads
pswNumOutboundConnectorThreads: 20
modifying entry cn=110,ou=ActiveDirectory,ou=Globals,cn=active[13], 
ou=GlobalConfig,ou=1.1,ou=IdentitySynchronization,ou=Services,dc=gt,dc=com

      

After these values are changed, the Identity Synchronization for Windows daemon on the Core machine is restarted to notify the System Manager to pick up the new configuration.
