Check the following settings on the database server:\n\n 1. The Oracle database and the Oracle Listener\n are up and running (check Windows services).\n\n 2. Confirm that there is a tns entry with the name SID.\n The file tnsnames.ora is under\n\n %ORACLE_HOME%\\network\\admin\n\n 3. Verify tns entry is valid by running:\n\n %ORACLE_HOME%\\bin\\tnsping \u003cSID\u003e\n\n2. Check if the log mode is set to Archive Log mode:\n\n sql\u003e archive log list\n\n If the database is in no-archive log mode, then return it to archive log mode:\n **Note:** This will take down the database. \n\n sql\u003e shutdown immediate;\n sql\u003e startup mount;\n sql\u003e alter database archivelog;\n sql\u003e alter database open;\n\n3. Enable database change block tracking. With database BCT off,\n incremental backup time is impacted. Change block tracking feature\n is available in Oracle Enterprise Edition. Run a SQL query to\n check that change block tracking is enabled. Run the query:\n\n sqlplus / as sysdba\n sql\u003e select * from v$block_change_tracking;\n\nTo enable change block tracking: \n\n sql\u003e alter database enable block change tracking\n using file '\u003cOracle home directory\u003e\\orcl.bct';\n\nBack up an Oracle database in a Windows environment\n---------------------------------------------------\n\n| **Note:** Database authentication is not supported for Oracle in a Windows environment. OS authentication is fully supported.\n\nTo back up an Oracle database in a Windows environment, follow these steps:\n\n1. Set the [Application Details \\& Settings for Oracle Databases](/backup-disaster-recovery/docs/backup/app-details-settings-oracle).\n\n2. Apply a backup plan to protect the database.\n\n**Known issue**\n\nOracle 19c SQL*Plus (sqlplus.exe) occasionally hangs on Windows when executing exit command (Doc ID 2820655.1).\nThis bug is specific to Windows. Oracle has confirmed that this issue occurs in SQL*Plus versions 19.10, 19.11 and 19.12. Oracle provided these solutions:\n\n- Use SQL\\*Plus 21.1 or later (or)\n- Apply patch:31466370. This patch is available for 19.11 and 19.13.\n\nRecover Oracle databases in a Windows environment manually using RMAN to a scheduled backup point if the archivelog is not protected through Backup and DR\n----------------------------------------------------------------------------------------------------------------------------------------------------------\n\nTo recover an entire Oracle database in a Windows environment:\n\n1. Mount the database backup snapshot from Backup and DR\n back to the Oracle server as detailed in [Mount an Oracle database as a standard mount](/backup-disaster-recovery/docs/access-data/mount-oracle).\n\n2. Set the database environment and start the database in no-mount state\n using the parameter file from the Backup and DR mounted volume\n (for example for a mounted database volume to E:):\n\n sqlplus / as sysdba\n sql\u003e startup nomount pfile='E:\\\u003csid\u003e___backup.ora';\n\n3. Create spfile from pfile:\n\n sql\u003e create spfile='%ORACLE_HOME%\\database\\spfile\u003csid\u003e.ora'\n from pfile='E:\\\u003csid\u003e___backup.ora';\n\n4. Start the database with spfile in the `nomount` state:\n\n sql\u003e shutdown immediate;\n sql\u003e startup nomount;\n\n5. Restore the control file using RMAN from the Backup and DR mounted volume:\n\n rman target /\n rman\u003e restore controlfile from 'E:\\cf-D_\u003csid\u003e-id_\u003cid\u003e.ctl';\n\n6. Mount the database:\n\n rman\u003e alter database mount;\n\n7. Catalog the datafile and the archive file folder\n from the Backup and DR mounted volume to RMAN:\n\n rman\u003e run\n {\n catalog start with 'E:\\datafile' noprompt;\n catalog start with 'E:\\archivelog' noprompt;\n }\n\n8. Restore and recover the database:\n\n rman\u003e run\n {\n restore database;\n recover database;\n }\n\n9. Open the database with reset log option:\n\n rman\u003e alter database open resetlogs;\n\nRecover Oracle databases in a Windows environment manually using RMAN to a scheduled backup point with roll-forward of Backup and DR-protected archivelog\n---------------------------------------------------------------------------------------------------------------------------------------------------------\n\n1. Mount the image from the source database server\n to recover. Mount the backup snapshot from Backup and DR back to the Oracle\n server as detailed in [Mount an Oracle database as a standard mount](/backup-disaster-recovery/docs/access-data/mount-oracle).\n\n2. Set the database environment and start the database\n in no-mount state using the parameter file from the Backup and DR mounted volume.\n In this example, the database backup image is mounted at: E:\\\\ and\n the protected archive log is mounted at: Z:.\n\n sqlplus / as sysdba\n\n startup nomount pfile='E:\\\u003csid\u003e___backup.ora';\n\n3. Create spfile from pfile:\n\n sql\u003e create spfile='%ORACLE_HOME%\\database\\spfile\u003csid\u003e.ora' from\n pfile='E:\\\u003csid\u003e___backup.ora';\n\n4. Start the database with spfile in the nomount state:\n\n ```sql\n shutdown immediate;\n startup nomount;\n ```\n\n5. Restore the control file using RMAN from the Backup and DR mounted\n archive log image:\n\n ```rman\n rman target /\n rman\u003e restore controlfile from 'Z:\\cf-D_\u003csid\u003e-id_\u003cid\u003e.ctl';\n ```\n\n6. Mount the database:\n\n ```rman\n rman\u003e alter database mount;\n ```\n\n7. Catalog the datafile and archivelog folder from Backup and DR mounted\n database image and archive log image to RMAN:\n\n ```rman\n rman\u003e run\n {\n catalog start with 'E:\\datafile' noprompt;\n catalog start with 'E:\\archivelog' noprompt;\n catalog start with 'Z:\\archivelog' noprompt;\n }\n ```\n\n8. Restore and recover the database:\n\n ```rman\n rman\u003e run\n {\n restore database;\n recover database;\n }\n ```\n\n For a specific point in time recovery run the recover command as follows: \n\n ```rman\n rman\u003e run\n {\n restore database;\n recover database until time \"to_date('\u003ctime stamp\u003e','yyyymmddhh24mi')\";\n }\n ```\n\n9. Open the database with reset log option:\n\n ```rman\n rman\u003e alter database open resetlogs;\n ```\n\n The database is available for read and write.\n\n### Watch script to watch for database volumes being mounted\n\nIf you create an application-aware mount, then you can use a watch script to\nshow the volumes being mounted from Backup and DR, and the Oracle\nprocesses running. Application-aware mounts are described in\n[Mounting an Oracle Database as a Virtual Application](/backup-disaster-recovery/docs/access-data/mount-oracle-virtualdb).\n\nWhen performing an application-aware mount, you can use this watch script.\nThe script location must be: C:\\\\Program Files\\\\Backup and DR\\\\scripts.\nScripts run on Windows hosts must be .bat or .vbs files. \n\n ```Windows\n @echo off\n :loop\n echo. \u003e watchtemp\n echo ------------------ \u003e\u003e watchtemp\n echo Oracle Processes \u003e\u003e watchtemp\n echo ------------------ \u003e\u003e watchtemp\n tasklist /svc | findstr oracle \u003e\u003e watchtemp\n echo. \u003e\u003e watchtemp\n echo ------------------ \u003e\u003e watchtemp\n echo Backup and DR Mounts \u003e\u003e watchtemp\n echo ------------------ \u003e\u003e watchtemp\n wmic volume get label, name | findstr Backup and DR \u003e\u003e watchtemp\n echo. \u003e\u003e watchtemp\n cls\n type watchtemp\n timeout 2 \u003e null\n goto loop\n ```\n\nWhich produces output like this: \n\n Oracle Processes\n ------------------\n oracle.exe 1492 OracleServiceORCL\n oracle.exe 3768 OracleServiceTestDB\n oracle.exe 872 OracleServiceTestDB2\n ------------------\n Backup and DR Mounts\n ------------------\n Backup and DR-Backup-ORCL D:\\mount_1"]]
