cache size

If you specify a maximum cache size less than 8 Mb, you will not be able to run Java applications.

The initial cache size is always less than 1. 1 Times the total database size.

Start with a fixed buffer cache size, and adjust the cache larger or smaller (example, 2% at a time).

Therefore, when tuning the cache size for your environment, allocate sufficient in-memory and disk space for the cache entries.

Check that the cache size is sufficiently large and that the cache hit ratio is high for each of the dynamic SQL statements being executed.

Thus, performance is best if the cache size is set to the maximum number of active instances expected during a typical workload.

On startup, the database allocates the specified maximum cache size from the system resources.

If you specify a maximum cache size greater than the available system resources, the server exits with a Not Enough Memory error.

It loads some of this into memory (the initial cache size) and keeps the remainder as swap space.

If the cache size is less than the set value, Lotus Quickr does not recycle the cache.

The formula for the default maximum cache size is an heuristic that attempts to achieve this balance.

If you specify a maximum cache size greater than the available memory, the server warns of performance degradation, but does not exit.

The hit ratio is a function of the cache size, the amount of underlying data, and the data access pattern.

To avoid cache size oscillations , the database server increases the cache size incrementally .

Benchmark tests are not perfect, but are a better indicator of microprocessor speed than clock rate or cache size specifications.

The cache size specifies the maximum number of entries that the cache can hold.

Note that if this variable is set too large, the Lotus Quickr server spends more resources to handle the larger cache size.

If the -c option is specified, the minimum cache size is the same as the initial cache size.

If the cache size is greater than the setting, the Lotus Quickr server recycles the cache size to the set value.

For information about UNIX initial cache size, see Dynamic cache sizing (UNIX).

By default, the minimum cache size is the same as the initial cache size.

Statistics such as the cache size, used entries, cache hits and misses, and many more provide a good overview of their usage patterns.

The most important characteristics are the cache size, default timeout values for cache entries, and the sharing policy.

The target cache size is never smaller than the specified or implicit minimum cache size.

The size you specify for the statement cache size should be relatively large. Typically this is in the range of 100-200.

Monitor the cache effectiveness and, based on cache usage, configure the cache size accordingly.

If you use larger page sizes, remember to increase your cache size.

By default, the initial cache size is assigned using an heuristic based on the available system resources.

This option improves slapindex performance when the database size exceeds the BDB cache size.

The maximum allowed cache size, in kilobytes.

The minimum allowed cache size, in kilobytes.

Once you've set the initial options and configured the directory and cache size you want, there's no need to change anything.

The chart in Figure 13 shows there were no statement discards after tuning the cache size.

You can use the -cl server option to adjust the minimum cache size.

Although ReadyBoost can use NTFS, it limits the maximum cache size to 4GB to accommodate FAT32 limitations.

There is no overflow to disk, so 1000is also the maximum cache size.

For information on the default cache size, see -c server option.

You should specify a cache size of about 50MB to ensure that there is enough space for all the classes.

If no -c option is specified, the minimum cache size on UNIX is 8 Mb.

You can change the initial cache size using the -c option.

Therefore, there is a limit to cache size.

The following statements set the cache size to 128 kb.

You would then be notified if the cache size grew to 5 MB again.

Exchange Server 2000 uses a maximum cache size of 858 MB.

The data source statement cache size can be tuned using a few different methods.

The percentage of file cache size against the true memory size

The current maximum theoretical cache size is 2GB. The cache size is limited by the following factors
