Oracle redirected restore: bug from Netbackup version 8.3 still affecting version 10?
Hi folks. I'm not a Netbackup admin/engineer but a member of the database team trying to understand the issue. Platform and setup: Netbackup ver. 10 Oracle 19c, RAC with Dataguard. Netbackup-managed backup. Multiple databases in RAC Background: We are attempting a redirected restore via RMAN. The source client is the production RAC database, referred to in the RMAN command using the appropriate Netbackup host catalog name (NB_ORA_CLIENT=<DBNAME>_<DBID>). We are aware of the redirected restore procedure and are following it correctly, as far as we know. We would get errors in the restore where RMAN would abort with this message: ORA-19507: failed to retrieve sequential file, handle="bk_dBLAHPROD_u9g217066_s6448_p1_t1142128838", parms="" ORA-27029: skgfrtrv: sbtrestore returned error ORA-19511: non RMAN, but media manager or vendor specific failure, error text: Failed to open backup file for restore. We've enabled debugging information in Netbackup and we saw these messages in the dbclient logs: 00:47:07.541 [765266] <4> sendRequest: sending buf = 1689256954 1689256954 /bk_dBLAHPROD_u9g217066_s6448_p1_t1142128838 00:47:07.541 [765266] <4> sendRequest: Date range: <-s 07/14/23 2:02:34>, <-e 07/14/23 02:02:34> 00:47:07.541 [765266] <4> serverResponse: entering serverResponse. 00:47:07.541 [765266] <4> serverResponse: initial client_read_timeout = <900> 00:47:07.541 [765266] <4> readCommMessages: Entering readCommMessages 00:47:09.541 [765266] <4> serverResponse: read comm file:<00:47:08 INF - Server status = 227> 00:47:09.541 [765266] <16> serverResponse: ERR - server exited with status 227: no entity was found 00:47:09.541 [765266] <16> RestoreFileObjects: ERR - serverResponse() failed 00:47:09.541 [765266] <4> closeApi: entering closeApi. 00:47:09.541 [765266] <4> closeApi: INF - EXIT STATUS 5: the restore failed to recover the requested files 00:47:09.541 [765266] <8> VxBSAGetObject: WRN - RestoreFileObject was not able to find the object.

A bplist of the oracle images will show that the image is actually present. This can occur on RAC clusters that have more than one database. In verifying the conditions relating to this bug, we indeed see the required backup piece via bplist: -rw-rw---- oracle asmadmin 700448768 Jul 14 02:00 /bk_dBLAHPROD_u9g217066_s6448_p1_t1142128838 But, as mentioned in the KB document: NetBackup will look for all possible images needed for the restore across all possible RAC catalog names associated with the client.The failure occurs when the last catalog name does not have any backup images in the requested time range and an error is returned. If you notice in the bplist output above, the timestamp for the backup piece is 02:00, but the time range it's being searched from the Netbackup catalog when doing the restore attempt is (as shown in the debug log): 00:47:07.541 [765266] <4> sendRequest: sending buf = 1689256954 1689256954 /bk_dBLAHPROD_u9g217066_s6448_p1_t1142128838 00:47:07.541 [765266] <4> sendRequest: Date range: <-s 07/14/23 2:02:34>, <-e 07/14/23 02:02:34> ... which obviously would preclude the backup piece it is interested in. Questions: is it possible that we are hitting this bug despite being in a different version than what is mentioned in the KB article? I'm aware that the KB document mentions:This issue has been seen in all present versions - just wanted to confirm it as the KB article doesn't clearly indicate that the bug has been resolved in versions post 8.3. the KB article refers to resorting to an EEB to workaround this issue - do we have any other options? Thank you all in advance.

Oracle RMAN job starts another job (copied)
Hi, We have an Oracle job (Archive log, Full) set with an RMAN script which works fine and now we'd like to have another copy of this job in another storage. So I simply created a job from the original one and changed the storage destination to the new place. So, the Original job is : policy name: job1, RMAN script : mysc.sh, storage: site1_stg I create a copy : Second job : policy name : job2, RMAN script : mysc.sh, storage: site2_stg What happens is strange! When I run Job1, Job1 is also automatically launched and run. I looked into the script and there is nothing related to the job policy name which may cause this. I also used a different script (with the same content of course) but the result was the same. As this is not the case in other jobs I doubt the script or Oracle Linux OS or Netbackup settings on the OS should be the cause. Any help would be appreciated. Thanks

Oracle Backup: large files parallel backup into many tape drives
Hello, community. Is there any way to backup Oracle DB in parallel in many tape drives (balanced well and independent of datafile sizes)? The only one i found is script-based backupwithRMAN parameter SECTION SIZE included in script. Which is not as convenient as Oracle Intelligent Policies unfortunately.

How can I do redirected RMAN restore to client with backup IP/hostname
Hello, In trying to do a redirected restore of an RMAN backup using NetBackup, I am getting the following error: 05/02/2017 11:32:47 - Error bpbrm (pid=14098) bpcd on fooz exited with status 48: client hostname could not be found 05/02/2017 11:32:48 - restored from image db-backup-source_1493623320; restore time: 0:00:08 05/02/2017 11:32:48 - Info tar (pid=0) done. status: 48: client hostname could not be found 05/02/2017 11:32:48 - Error bpbrm (pid=14098) client restore EXIT STATUS 48: client hostname could not be found 05/02/2017 11:32:52 - end Restore; elapsed time 0:00:15 Oracle policy restore error (2801) My guess is the the "hostname" in question is the destination client, which is known to Netbackup as: fooz-bkp (since we back it up using a backup network). Normally not an issue on a normal redirected restore, but I'm not sure how to specify the destination client within the RMAN commands, which are being run from fooz. This is a 7.6.0.4 NB env. restore source Client is linux, and restore destination is a linux media server . Thanks

Can we limit Oracle backup retries in Netbackup 7.7.3?
Hi, Good day! Just wondering if we can limit or forego with automatic oracle backup retries? As experienced, everytime an oracle backup encounters errors, as long as it is still within the backup window, it will continue to rerun the job. Netbackup version: 7.7.3 Master server OS: AIX 6.1 Oracle version: 11G Thanks in advance! - alain
