Status Codes

 An application that calls the MicroKernel can return this status

code if the DBNAMES.CFG file contains a named database

definition specifying a data location on a different server.

97: The data buffer is too small

The application either tried to read or write a record that is longer

than the current allowed settings for the MicroKernel or the Btrieve

Requester, as follows:

 For an Update, Insert, or Create operation, the application

receives this status code if the data buffer length it specifies for

the record exceeds the message buffer length.

 For a Get, Step, or Stat operation, the application receives this

status code if the message buffer is shorter than the length of the

data the MicroKernel would return, regardless of the data buffer

length specified in the application.

 For a Get Chunk or Update Chunk operation, the total size of the

retrieved or updated chunk exceeds the message buffer length.

 DOS Requesters only: Reload the Btrieve Requester and specify a

higher value for the message buffer size. This is done using the

/D parameter which is documented in Getting Started With

Pervasive PSQL.

 For Windows servers, verify that the Maximum Packet Size

registry setting is 576 decimal or 240h. The path to the

MaxPktSize registry setting is

HKEY_LOCAL_MACHINE\System\currentControlSet\

Services\NwInkIPX\NetConfig\MaxPktSize.

100: No cache buffers are available

This indicates that the MicroKernel has used all the cache buffers it

allocated at load time.

You may encounter this status code if your application uses a large

number of write operations (insert, update, and delete) in a user

transaction. The current implementation of the MKDE requires all

modified pages to reside in cache until the transaction completes.

NOTE: On a machine with limited available memory, you may not

be able to successfully complete very large transactions with

thousands of write operations.
