I have some new servers I am setting, DB2 V10 on AIX. We will be using STMM for the most part, however, at the instance level we will be setting a max amount of memory for the instance. Has anyone come with a recommendation on how much memory to allocate for an instance at the server level? Normally we go with 75% for servers that only have the database running on them (application is on other servers). If anybody knows of a document with best practices for this that would be helpful.
