Folks Even though log_buffer is set to 1M, on Database Startup it is automatically getting reset to 14MB (shown below) Qs 1 - Is there a Patch for this Bug? Qs 2 - Alternatively, Can _ksmg_granule_size be manually set to a small Value e.g. 1M? Is it safe to do so? Oracle 10.2.0.3 HP-UX 11.31 Cheers & Thanks indeed P.S. Metalink Note:351857.1 posting:- This is already explained in bug 4592994.<https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_id=4592994&p_database_id=BUG> In 10.2 the log buffer is rounded up to use the rest of the granule. The granule size can be found from the hidden parameter "_ksmg_granule_size" and in your case is probably 16Mb. The calculation for the granule size is a little convoluted but it depends on the number of datafiles etc.. **************** CAUTION - Disclaimer ***************** This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).
