WARNING: aio_wait: errno = nn.

Cause:

While the database server was waiting for an I/O request to complete, it generated error number nn on an operation that it was attempting to execute.

Action:

Contact Technical Support for assistance.

WARNING: Buffer pool size may cause database server to get into a locked state. Recommended minimum buffer pool size is num times maximum concurrent user threads.

Cause:

There are not enough buffers in the buffer pool. The database server could use all available buffers and cause a deadlock to occur.

Action:

Change the buffers field in the BUFFERPOOL parameter in the ONCONFIG file to the number that this message recommends. For more information on the BUFFERPOOL parameter, see BUFFERPOOL..

warning: Chunk time stamps are invalid.

Cause:

A sanity check is performed on chunks when they are first opened at system initialization. The chunk specified did not pass the check and will be brought offline.

Action:

Restore the chunk from a dbspace backup or its mirror.

Warning: name_old is a deprecated onconfig parameter. Use name_new instead. See the release notes and the Informix Administrator's Reference for more information.

Cause:

A deprecated ONCONFIG parameter was used. This message displays the first time that you use a deprecated parameter. The shorter form of the message displays thereafter.

Action:

Use the suggested alternative ONCONFIG parameter.

Warning: name_old is a deprecated onconfig parameter. Use name_new instead.

Cause:

A deprecated ONCONFIG parameter was used.

Action:

Use the suggested alternative ONCONFIG parameter.

Warning: Unable to allocate requested big buffer of size nn.

Cause:

The internal memory allocation for a big buffer failed.

Action:

Increase either virtual memory size (SHMVIRTSIZE), the size of the added segments (SHMADD), or your total shared-memory size (SHMTOTAL).

You are turning off smart large object logging.

Cause:

These changes will become the new sbspace default values. Changes have been made to the sbspace. The onspaces utility will read and update 100 smart large objects at a time and commit each block of 100 smart large objects as a single transaction. This utility might take a long time to complete.

Action:

This informational message occurs when you issue the following command:

onspaces -ch sbspace -Df "LOGGING=OFF" -y

For more information, see Change Sbspace Default Specifications.
