Hi Chris, The appropriate sections of the my.cnf (or my.ini on windows) file to edit are
# # Set the innodb engine parameters # innodb_data_home_dir = /u01/app/dmc/db/dmcpdb innodb_data_file_path = ibdata1:10M:autoextend innodb_log_group_home_dir = /u01/app/dmc/db/dmcpdb innodb_log_arch_dir = /u01/app/dmc/db/dmcpdb innodb_buffer_pool_size = 32M innodb_additional_mem_pool_size = 20M innodb_log_file_size = 5M innodb_log_buffer_size = 8M innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 50 As you can see, the log file size is probably not the same as you had in the previous my.cnf. Your previous my.cnf must have been overwritten along with all the appropriate parameters. To get past the error message you are seeing, either change the innodb_log_file_size parameter or delete the log file and let innodb create it itself. All of this is described in the manual in chapter 16, the paragraph you need is probably 16.4 HTH and you get things going soon.

I'm having a Very Bad Day trying to upgrade a MySQL server from 4.0.18 to 4.1.5. After several problems resolved, I'm almost there--got the new engine to recognize the old dbs, etc. But now, after what I thought would be an ordinary removal/reinstall of the daemon (most of the problems related to the new daemon picking up defaults from an install into another location), the Win service won't start. Here's the relevant section of the error log: InnoDB: Error: log file .\ib_logfile0 is of different size 0 19922944 bytes InnoDB: than specified in the .cnf file 0 5242880 bytes! 041014 18:20:37 [ERROR] Can't init databases 041014 18:20:37 [ERROR] Aborting 041014 18:20:37 [NOTE] MySQL: Shutdown complete (Trying to start the service from Windows gives Error 1037) Can I edit the cnf file? Clear the InnoDB logfile? I'm getting pretty desperate--site's been down a long time. Any help much appreciated. --Chris -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
