Status Codes

 You may have attempted to open a file with two different

Workgroup engines that are mapped to the files using different

share names. The MicroKernel attempts to correct this, but

cannot do so in all cases. Make sure each computer is mapping

to the same share name.

120: Maximum number of B-Tree index levels reached

This status code may result if you use a large key size for an index and

small page sizes. Index keys can fill the B-Tree to the allowable depth

even though the B-Tree is not completely full.

To prevent this status code, try one or both of the following:

 Rebuild the data file with a larger page size to increase the

number of keys stored per page.

 Turn on index balancing to maintain a better distribution of

index keys (performance decreases somewhat with index

balancing on). See Index Balancing in Advanced Operations

Guide.

130: The MicroKernel ran out of system locks

This status code is obsolete in MicroKernel versions 6.15 and later.

This status code can indicate a temporary condition in which no

system locks are currently available. The following are example cases:

 A single client is performing a very large transaction, in which

thousands of records are being modified.

 Many clients are performing large transactions concurrently.

A client can receive this status code whether or not it is in a

transaction. In some cases, a client can simply retry the failed

operation. If other clients have released system locks in the interim,

the retried operation may succeed. If a client in a transaction receives

this status code, end or abort the transaction. If the transaction is

very large, consider breaking it into multiple, smaller transactions.

You can also use the Setup utility to lower the number of system locks

devoted to explicit locking. To do so, lower the values assigned to the

Number of Locks and/or Number of Sessions configuration options.
