Sun Java System Identity Synchronization for Windows 6.0 Deployment Planning Guide

Increasing Connector Worker Threads

By default each Directory Server and Active Directory connector uses four worker threads to apply changes. This number is increased in the Global Telco deployment to improve connector performance, especially during idsync resync operations. The number of connector threads is stored in the configuration directory in the pswNumOutboundConnectorThreads attribute, which is in the pswSunDirectoryGlobals entry and the pswActiveDirectoryGlobals entry. 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 shown here:
```
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 shown here:
```
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 system with the Identity Synchronization for Windows Core, is restarted to notify the System Manager to pick up the new configuration.

Note –

Increasing the number of connector threads also increases the maximum number of LDAP connections that the connector will keep open to the directory.
