After you utilize the Develop DATABASE assertion, you need to finish additional actions before you have an operational database.
For instance, duplicate the text initialization parameter file from /u01/prod1/oracle/dbs to /u03/clone1/oracle/dbs. The title and site with the file ought to match the identify and site specified in the STARTUP NOMOUNT command during the modified SQL script.
Employing built-in, shared, and concurrently mounted storage, for example Oracle ASM and Oracle ACFS for database files and also for unstructured details, permits Oracle Grid Infrastructure to restart an Oracle Database on the failover node considerably quicker than any cluster Answer that depends on failing about and remounting volumes and file techniques.
When an Oracle occasion starts, it reads an initialization parameter file. This file could be a textual content file, which may be designed and modified having a textual content editor, or even a binary file, which is produced and dynamically modified because of the database.
Transform any initialization parameter that is specific towards the CloneDB database environment, like parameters that control SGA dimensions, PGA focus on, the quantity of CPUs, and so forth. The CLONEDB parameter has to be set to TRUE, and the initialization parameter file includes this parameter.
Despite the fact that you are able to open up the binary server parameter file which has a textual content editor and look at its text, will not manually edit it. Doing this will corrupt the file. You will not be able to start out your instance, and In case the instance is running, it could fall short. After you challenge a STARTUP command with no PFILE clause, the Oracle instance lookups an running procedure–unique default area for the server parameter file from which to read initialization parameter options.

Single-occasion would not necessarily mean that just one Oracle occasion can reside on a single host Pc. In actual fact, various Oracle occasions (and their associated databases) can run on just one host computer. Only one-occasion database is actually a database that's accessed by just one Oracle occasion at any given time, instead of an Oracle RAC database, that is accessed concurrently by a number of Oracle scenarios on a number of nodes.
See your operating procedure documentation for Guidelines. Such as, on Windows, use the subsequent command to configure the database services to get started on the instance on Pc restart:
