PERFORMANCE
You also specify the location of the Domino Change Control database (DOMCHANGE.NSF). By default, Activity Trends automatically selects a server. However, you must specify the Domino Change manager server in the Configuration Settings document. Use the default unless you want to use a local replica or are working remotely and want to use a server that has a replica of the Domino Change Control database.
Resource balancing distributes database activity across three bins:
Balancing according to the bins, ensures that the spread of heavily used and lightly used databases are evenly distributed across the servers. This results in more predictable usage patterns, increased availability, and more efficient use of resources.
Deciding the exact percentages for each of the bins depends on how your organization uses its databases and the type of server being balanced (mail server versus application server). For mail servers in most organizations you may want to increase the size of the light bin and decrease the size of your heavy bin, while for application servers the mix may be different.
You can view profile charts on bin activity and weigh percentages to improve load balancing.
You also specify how Activity Trends analyzes the server resource capacities. By default, server capacities are determined relative to other servers in the list. For example a server that has a capacity of x1 transactions has half the transactional capability (CPU) of a server at x2. You could, however balance resources based on actual values (such as the number of transactions per day, or the total amount of disk space available). Using the example above, you would specify the servers as having a capacity of 10,000 and 20,000 transactions. However, if you choose to balance resources based on actual values, you have to know that the servers involved can actually handle the capacities specified.
Another way in which you indicate server resource capabilities, is to specify how the server volume is determined. You can either use server volume and file system information when resource balancing, or ignore volume information and treat all space as flat. The default is to use the volume information, which uses the different physical volumes and their sizes that comprise the space available to Domino, rather than just the total amount of space on the server. Volume balancing is recommended. This may produce plans in which a database moves to a different server and has a different destination path because of space requirements on a particular volume on the destination server.
