WEBSPHERE PORTAL V6.1 TUNING GUIDE
com.lotus.cs.services.directory.ldap.BasicLDAPDirectoryService.user
Default size: 2000, default lifetime: 10780, usage pattern: regular.
This cache stores user-specific information read from the LDAP. It scales with the
number of users working with DEPP portlets. The cache is accessed during rendering a
DEPP portlet, whenever those need user information. This could be multiple times per
page reload. In addition the cache is accessed whenever a mail server is accessed.
Creating a cache entry is fairly expensive and can involve multiple LDAP lookups. An
entry into the cache is medium-sized.
com.lotus.cs.services.directory.wmm.WMMDirectoryService
Default size: 4000, default lifetime: 10980, usage pattern: regular.
This cache stores user-specific information read from the LDAP and WMM. Entries in
this cache represent a more complete set of data stored in the LDAP than is available in
other parts of WebSphere Portal. The cache scales with the number of users working
with DEPP portlets. The cache is accessed during rendering a DEPP portlet, whenever
those need user information. This could be multiple times per page reload. In addition
the cache is accessed whenever a mail server is accessed. Creating a cache entry is
fairly expensive and can involve multiple LDAP lookups. An entry into the cache is
medium-sized.
com.lotus.cs.services.UserEnvironment
Default size: 2000, default lifetime: 10880, usage pattern: regular.
This cache stores user-specific information. Entries represent a compilation of credential
information for one user to different LDAP directories and details which data on the given
user can be found in which directory. For example, the general info may be stored in one
directory, but the mail server and file may be in another. The cache scales with the
number of users working with DEPP portlets. The cache is accessed whenever a DEPP
portlet is accessed. Creating a cache entry can be fairly expensive since multiple
resources might be queried. An entry to the cache is medium-sized.
com.lotus.cs.services.domino.DominoService
Default size: 2000, default lifetime: 11080, usage pattern: regular.
This cache stores user-specific Domino information. It is used for awareness functions. It
scales with the number of users working with the corresponding function. The cache is
accessed whenever awareness functions are requested during page rendering. Creating
a cache entry is cheap and simply involves creating a new Domino session. An entry to
the cache is medium-sized.
