You might encounter the following issues while performing backups.
Backups fail when credentials include a backslash character (\)
When you enter credentials that include a backslash character (\) for an application agent in the
PowerProtect Data Manager UI, the backups fail.
For example, when you enter a password for the operating system or database user that includes the backslash character, subsequent backups fail with the following error message:
systemErr: Unable to log in.
This error might occur when updating the password for a storage unit.
To resolve this issue, type \\ (double backslash) instead of \ (single backslash) when you enter the credentials for an application agent in the
PowerProtect Data Manager user interface.
Oracle configuration or backups might fail in a multi-user Oracle environment
In a multi-user Oracle environment where a protection policy is configured with the assets of multiple users, the Oracle configuration or backup operations might fail.
To resolve the configuration and backup issues, ensure that the multi-user Oracle environment meets the following requirements:
All the Oracle users are members of the same Oracle group.
All the Oracle users have group read and write access permissions to the
$RMAN_AGENT_HOME directory.
The Oracle RMAN agent installation pathname has the 750 permission setting.
Oracle Incremental Merge backup error occurs after multiple switches between BoostFS and NFS protocols
When you switch multiple times between the BoostFS and NFS protocols during Oracle Incremental Merge backups of Oracle ASM RAC assets, a backup might fail with the error codes ORA-17503, ORA-17500, and ORA-19504.
As a workaround, run the following commands as the Oracle user:
cd $ORACLE_HOME/rdbms/lib
run >> make -f ins_rdbms.mk dnfs_off
Oracle Incremental Merge backup might fail in RAC environment with database or wallet authentication
When you use database authentication or Oracle wallet authentication in a RAC environment, an Oracle Incremental Merge backup might fail with the following error message:
RMAN-03009: failure of backup command on <channel_name> channel at <data_and_time>
ORA-19504: failed to create file <file_name>
As a workaround, perform the appropriate steps, depending on whether you use database or wallet authentication:
For database authentication, specify the service name in the
Net Service Name field in the
PowerProtect Data Manager UI.
For example, orcl.lab.emc.com is the service name in the
tnsnames.ora file as follows:
To enable the Oracle Incremental Merge backups with database authentication in the RAC environment, specify orcl.lab.emc.com as the net service name in the
PowerProtect Data Manager UI:
Select
Infrastructure > Assets, and then click the
Oracle tab.
Select the assets by clicking the check box next to each required asset name.
Select
More Actions > Set Credential.
In the
Set Credential dialog box, specify the required values for
Database Credentials:
Select
Database User or
Wallet, and select the credentials from the menu.
Type
orcl.lab.emc.com in the
Net Service Name text box.
For wallet authentication, run the
mkstore command for each node in the RAC, to save the required credentials including the service name in the wallet.
For example, orcl.lab.emc.com is the service name in the
tnsnames.ora file as follows:
To enable the Oracle Incremental Merge backups with wallet authentication in the RAC environment, run the following type of
mkstore command to add the required credentials for each RAC node:
You can run the following
mkstore command to list the credentials from the wallet:
mkstore -wrl <wallet_location> -listCredential
Oracle Incremental Merge self-service script fails when not run in $RMAN_AGENT_HOME directory
An Oracle Incremental Merge self-service script fails when you run the script outside of the $RMAN_AGENT_HOME directory, which is the Oracle RMAN agent installation directory. This type of self-service script includes one or more
ddbmoim commands as described in the latest version of the
PowerProtect Oracle RMAN Agent Administration Guide (for the stand-alone Oracle RMAN agent).
As a workaround, run the Oracle Incremental Merge self-service script or the
ddbmoim commands from the $RMAN_AGENT_HOME directory. For example:
Go to the $RMAN_AGENT_HOME directory:
cd /home/oracle/opt/dpsapps/rmanagent
Run one of the following
ddbmoim commands to perform an Oracle Incremental Merge self-service backup:
Oracle backup progress remains at 0% until completion
In the
Protection Jobs window in the
PowerProtect Data Manager UI, the progress of an Oracle backup is reported as 0% in the
Status column. The progress status remains at 0% until the backup completes.
Self-service backup error occurs for an unmanaged asset
When two assets on a host have the same DBID and only one asset is managed by
PowerProtect Data Manager, a backup of the asset that is not managed by
PowerProtect Data Manager might fail with the following error message:
sbtbackup: Unable to find the asset in the settings file. for a dataguard instance, make sure to specify DBUNIQUE_NAME parameter in rman script.
To resolve this issue, set the
ALLOW_BACKUP parameter in the
$RMAN_AGENT_HOME/config/rman_agent.cfg file to the SID of the asset that is not managed by
PowerProtect Data Manager. For example:
ALLOW_BACKUP = orcl2
Self-service backup error related to top-level pathname
If a self-service backup fails with the following type of error, you must complete the required top-level directory changes:
Reason for failure: orcl failed due to error message: The backup operation failed for the instance 'orcl' with dbid '1585115093' due to the following error: RMAN-03009: failure of Control File and SPFILE Autobackup command on CH0 channel at 12/09/2020 13:16:52
ORA-19502: write error on file "c-1585115093-20201209-06", block number 1 (block size=16384)
ORA-27030: skgfwrt: sbtwrite2 returned error
ORA-19511: non RMAN, but media manager or vendor specific failure, error text:
sbtwrite2:The top-level pathname must be specified in backup piece format for assets configured with PowerProtect Data Manager.
Recovery Manager complete.
Self-service operations with data-in-flight encryption
PowerProtect Data Manager supports in-flight encryption for both centralized and self-service Oracle backup and restore operations. The
/opt/dpsapps/agentsvc/Addons/global_config.json file on the Oracle client contains option settings that affect the in-flight encryption during self-service operations.
NOTE:
The
/opt/dpsapps/agentsvc/Addons/global_config.json file is created automatically. You cannot edit the contents of the file.
Centralized settings take precedence over settings in the
/opt/dpsapps/agentsvc/Addons/global_config.json file. Stand-alone self-service operations without
PowerProtect Data Manager do not support in-flight encryption.
The status of in-flight encryption during self-service operations depends on the following settings:
If the
encryptionOverTheWire option setting in the
/opt/dpsapps/agentsvc/Addons/global_config.json file is TRUE, then in-flight encryption is enabled.
If the
encryptionOverTheWire option setting in the
/opt/dpsapps/agentsvc/Addons/global_config.json file is FALSE, then in-flight encryption is disabled.
If the
/opt/dpsapps/agentsvc/Addons/global_config.json file does not exist or is corrupted, then in-flight encryption is disabled. Applicable information is recorded in the operational logs.
Data-in-flight encryption provides more information about the
PowerProtect Data Manager support of in-flight encryption.
Oracle self-service jobs that run indefinitely
When you perform an Oracle self-service backup or restore, the backup or restore job continues to run indefinitely and the job status appears as In Progress in the
PowerProtect Data Manager UI.
As a workaround, always exit from the RMAN session after each backup or restore job. Then the job status changes to Successful or Failed in the
PowerProtect Data Manager UI, depending on the RMAN session output.
Incorrect self-service backup report for different backup types in same session
When you perform different types of self-service data backups such as full and incremental backups with archive log backups in the same RMAN session, the backups job can be reported incorrectly in the
PowerProtect Data Manager UI.
For example, you might run the following backup command to perform the full and incremental backups with archive log backups in the same RMAN session:
backup incremental level=0 database plus archivelog delete input tag='oracle-L0'
In this case, the Oracle self-service backups job name and subtype can be reported as LOG instead of FULL or INCREMENTAL in the
PowerProtect Data Manager UI.
To prevent this issue, perform a self-service data backup and archived log backup by using separate backup commands.
Performing self-service backups of Oracle databases provides examples of RMAN backup scripts that perform a full backup of a database and its archive logs in separate statements.
Missing duration value for centralized backup
A centralized Oracle backup succeeds, but the backup job duration at the asset level appears as 0 ms on the
Step Log tab and
Details tab in the
PowerProtect Data Manager UI.
The
Step Log tab and
Details tab appear in the
Job ID Summary window, which you can access by selecting
Jobs > Protection Jobs and clicking the job ID next to the job name.
As a workaround, view the correct backup duration in the
Duration column in the left pane that has a grid format.
Issue with onboarded backup copies
You might encounter an issue with onboarded Oracle backup copies.
PowerProtect Data Manager does not delete any Oracle backup copies that are onboarded but not associated with a protection policy, even when the backup copies are expired.
