I have had the wonderful task of learning how to backup and restore Oracle on Linux.
Experience with Linux - 2 weeks
Experience with Oracle - 1 week
I am reading a Linux for Dummies Book and purchased RMAN Backup & Recovery. I am still a dope when it comes to both technologies so please be aware when providing insight for my questions.
I was able to backup the Oracle DB using the hot_database_backup script and it seems to have completed successfully. But I have no idea how to restore the DB. I edited the restore_database script and ran it and it completed successfully with 0 zero byte count. I realized that I have no idea how I can select a backup from a specific day. Is using the hot_database_backup script going to limit me? For testing our company is fine doing only Full backups I figure I will try to learn how to do differential backups later. I tried opening the java applet using XQuartz but that proved an epic failure and spend days trying to fix the problem. Is there an advantage to using the Java Applet when using SSH to the Linux Server?
Lastly I have been reading about configuring a Recovery Catalog, I understand this is optional so wondering if this is something I should try to do or is it ok can I hold off on trying to accomplish this.
Now I understand why Oracle DBA make big money, it is complicated, and I am just hoping for some insight on what I should be doing. I read the Symantec Documentation and it was very helpful with performing the backup but completely useless in doing a restore and support will not help in performing the restore.
