IBM Tivoli Directory Server Tuning

The following table shows the tuning values used for the directory servers.

How-to-Set:These values are in the file /opt/IBM/ldap/V6.0/etc/SchemaV6.0/ibmslapd.conf. You must restart the LDAP server after changing these values.

Table 28: IDS Tuning in Vertical Cluster

Parameter	Setting Used
Ibm-slapdACLCacheSize	250000

Ibm-slapdEntryCacheSize	250000

Ibm-slapdFilterCacheSize	250000

Ibm-slapdFilterCacheBypassLimit	7500

The IBM Tivoli Directory Server uses IBM DB2 as the database server. The database instance and alias are named IDSLDAP. We applied the following tuning to this database:

db2 “update db config for idsldap using dbheap 4800”

db2 “update db config for idsldap using num_iocleaners 5” db2 “update db config for idsldap using num_ioservers 10” db2 alter bufferpool IBMDEFAULTBP size 88500

db2 alter bufferpool LDAPBP size 3690
