The file name specified for server logs can contain %p and %d, which are replaced at startup with the server Process Identifier and the current date, respectively. For example: dbms_%d_%p.log. This prevents the server from writing to the wrong log.

Such file names can be specified on the variables II_DBMS_LOG, II_GCA_LOG, II_GCD_LOG, II_GCN_LOG, II_ODBC_LOG, and II_API_LOG.
