DB Block Size (KB): The size in KB of one database block on disk.
Database Cache Information
Current Size (KB): The current size in KB of the specified cache.
Items Cached: The number of items in the specified cache.
Old Versions Cached: The number of old versions in the specified cache. Old versions of cache items are kept to maintain the consistency of read transactions in the database. If one thread is in a read transaction and another is in a write transaction, old versions of blocks modified by the writer are maintained on behalf of the reader so that the reader's results are guaranteed to produce a consistent view during the life of its transaction even though modifications are taking place during that time.
Hits: The number of times an item was successfully accessed from the specified cache.
Hit Looks: The number of items looked at in the cache before an item was successfully accessed from the specified cache. The Hit Look to Hit Ratio is a measure of cache lookup efficiency. Normally, the ratio should be quite close to 1:1.
Faults: The number of times an item was not found in the specified cache and had to be obtained in a lower-level cache or from the disk.
Fault Looks: The number of items looked at in the cache before it was determined that the desired item was not in the specified cache. The Fault Look to Fault Ratio is a measure of cache lookup efficiency. Normally, the ratio should be quite close to 1:1
Database Cache Configuration
Cache Adjust Percentage: The percentage of available memory allowed to be used for the record and block caches combined.
Cache Size Constraints: While dynamically adjusting the cache configuration, you should follow the specified constraints. Namely, use no less than the specified amount of memory for the cache and no more than the total amount of available memory minus the specified amount.
Hard Limit: Allows you to specify the exact amount of system memory to be used for the cache.
Cache Maximum Size: The size in KB of the record and block caches combined.
Block Cache Percentage: The percentage of the system memory available for caching that should be allocated to the block cache. The remaining percentage is allocated to the record cache.
Cache Adjust Interval: Interval that only applies when Dynamic Adjust is set. It controls how often the cache size is adjusted based on the specified percentage and constraints.
Cache Cleanup Interval: Controls how often unused old versions are removed from the cache.
Cache Settings Permanent: When checked, overwrites any previously saved settings or system defaults with any changes submitted via iMonitor.
