Error Messages

This appendix describes the error messages that you may encounter using Oracle Database Cache.

## Message Formats

To help you find and fix errors, Oracle Database Cache embeds object names, numbers, and character strings in some messages. In this appendix, these embedded variables are represented by string, number, date, or character.

All messages displayed by Oracle software are prefixed by text that indicates which program issued the message. Oracle Database Cache uses the prefix WTE. For lists of the prefixes used by other Oracle products, see Oracle8i Error Messages.

Note that directory specifications in the error messages usually use the UNIX convention. Unless otherwise noted, the path of the directory specification is the same for other platforms. Only the directory and file delimiters, such as slashes, may be different.

## Oracle Database Cache Error Messages

  Action: Check that the user who started Oracle Database Cache has write access to the directory. Check that there is available disk space on the cache node.

WTE-03504 Error updating list of users: Failed to drop users already deleted from origin database

  Cause: Oracle Database Cache could not drop one or more users from the cache when the list of users was updated. The user or users were already dropped from the origin database. However, the users could not be dropped from the cache because they were connected to the cache.

  Action: When the users disconnect from the cache, use Cache Manager to update the list of users.

WTE-03506 Error altering the size of data file string

  Cause: The size of the data file could not be altered. If you tried to decrease the size of the file and doing so would result in loss of data, Oracle Database Cache prevented the decrease in size. If you tried to increase the size of the data file but there was insufficient disk space, Oracle Database Cache prevented the operation.

  Action: Use Cache Manager to check the amount of unused space in each file before decreasing the size of the file. If insufficient disk space prevents increasing the size of an existing file, add a new data file to a different disk (one that has sufficient disk space).

WTE-03507 Error adding the new data file string

  Cause: Oracle Database Cache could not add a new data file. Possible causes are: the directory does not exist, the Cache Manager user does not have appropriate privileges to create a file in the directory, the file already exists, or there is insufficient disk space.

  Action: If the directory does not exist, create the directory. If the user does not have the appropriate privileges to create a file in the directory, grant the user the appropriate operating system privileges. If the file already exists, specify a different file name. If there is insufficient disk space, specify a directory on a different disk or delete unneeded files from the current disk.

WTE-03508 Error getting cache information: Failed to get number of blocks from init.ora file

  Cause: The parameter db_block_buffers was not found in the init.ora file.

  Action: Check the init.ora file to verify that it contains the parameter db_block_buffers.
