Using Messaging Server 64-bit Edition
Beginning with the release of Messaging Server 6.3, on Solaris OS, you have had the choice to install the 64-bit version of Messaging Server. The Communications Suite Product team now recommends that you install 64-bit Edition for new installations on Solaris OS, and upgrade your existing Solaris OS 32-bit Messaging Server deployments to the 64-bit version as time permits. You should no longer be installing the 32-bit version of Messaging Server on Solaris OS.
Reasons to use or switch to Messaging Server 64-bit Edition include:
- Solves the problems with large
store.idxfiles (described in Large store.idx Files Issue). - Ability to run a reasonable number of
imapdprocesses instead of running dozens of them. - Better LDAP cache utilization (see also LDAP Cache Tuning in Messaging Server).
