Hello good friends,
I am having a problem backing up my archivelogs. I have research everything posting here but non seems to help. I have try backing up using RMAN & Grid Control but still end up with the same issue. I am able to do a full back but not the archivelog. My archive destinations are:
Node 1 - /u02/oracle/admin/prod/arch/prod1
Node 2 - /u02/oracle/admin/prod/arch/prod2

Terminal window – If I cd into prod2 from node 1 I don’t see archive log listed and vise-versa. Everytime I attempt to backup from a node—I always receive the error message: expected archived log not found at the other node archivelog directory. For example:

RMAN> connected to target database: PROD (DBID=35109652)
using target database controlfile instead of recovery catalog
RMAN> echo set on
RMAN> set command id to 'BACKUP_PROD.WORLD__101907094924';

I am thinking that the node are not seeing the archivelogs for each other. My specifications are:

Let me know if you need any other info to help.

If there is an expert that willing to spend time on the phone with me tonight I will also appreciate that.

Godd bless

How are you allocating your channels? You should allocate your channels as such:

ALLOCATE CHANNEL c1 DEVICE TYPE DISK CONNECT 'SYS/oracle@prod1';
ALLOCATE CHANNEL c2 DEVICE TYPE DISK CONNECT 'SYS/oracle@prod2';

Hello and thanks for the response. Below is the error I got after allocating channels as you suggested.

Channel c2 was allocated because I am running the backup from that node. It seems RMAN is unable to allocate channel to node 2. Do you know what the problem is? My back up directory is “/backup/prod/backup_db” and is visible on node 1 only. I don’t think this make a different since the archivelogs are known by both nodes. I will like to add that I have double check and the issue does not have anything to do with wrong password. I changed the password several times--commit and retry but now way.

You need to connect as SYS in the allocation of your channel.

Good afternoon my friend,
I connected as sys but still had the same problem:

RMAN> RUN
2> {ALLOCATE CHANNEL c2 DEVICE TYPE DISK FORMAT '/backup/prod/backup_db/%U' MAXPIECESIZE 2G CONNECT 'SYS/change_on_install@prod1';
3> ALLOCATE CHANNEL c1 DEVICE TYPE DISK FORMAT '/backup/prod/backup_db/%U' MAXPIECESIZE 2G CONNECT 'SY/change_on_install@prod2';
4> backup (archivelog all);
5> }

I know the password is correct because I try it several times...lock key is off. Here is my RMAN perm configuration----which should have no effect on channel allocation if I am right:

RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u01/oracle/product/10.1.0.5/db/dbs/backup_ctr_spfile/%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL 1 DEVICE TYPE DISK CONNECT 'sys/change_on_install';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'sys/change_on_install';

CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/oracle/product/10.1.0.5/db/dbs/snapshot_ctr_file/scontrolfile.ctl';

Thanks for your help so far...

As a test, try to clear your channels with:

CONFIGURE CHANNEL 1 DEVICE TYPE DISK CLEAR;
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CLEAR;
CONFIGURE CHANNEL DEVICE TYPE DISK CLEAR;


Can connect remote as SYSDBA with simply SQL*Plus?

Also, I assume that's a typo for the channel 1 allocation for the SYS name?

Hi, thanks again for the help. I cleared the various channel configurations, and try the backup but it didn’t work. The channels couldn’t be allocated. I then try another means---with my last attempt the channels were allocated but it claimed not to find the archivelogs. I have done CROSSCHECK several times so I didn’t do it this time. Here are the outputs. It shows that I can connect to SQL*PLUS as sysdba, and also the archive log:

oracle:@ppdbs1:/home/oracle> export ORACLE_SID=prod1

Here is the archivelog directory. I’m login from prod1/node1. I am able to see the archive logs for prod1 but not prod2. When I login to prod2/node2 I can see its archive logs but not that for node1. It seems they are not visible to each other. How can I resolve this? Your help will be highly appreciated.

oracle:@cernappdbs1:/u02/oracle/admin/prod/arch> ls

oracle:@cernappdbs1:/u02/oracle/admin/prod/arch/prod2> ls

As you can see there is none visible on prod2 while login through node1. If I where login to node2 it will be visible but not that for node1. Pls let me know if I'm posting too much info.

Your test connection as SYS was only to the local database (prod1). You need to perform the SQL*Plus connection as SYS from prod1 node as follows:
sqlplus sys/password@prod2 as sysdba


After I had a closer at your code, also try a local connection to your database as:
sqlplus sys/password@prod1 as sysdba


In addition, check to ensure that your REMOTE_LOGIN_PASSWORDFILE = EXCLUSIVE for each instance. Your password file may not be available or incorrect.

Hi, thanks for your help again. You were right!!! The REMOTE_LOGIN_PASSWORDFILE was changed but sys password was not changed. I made the changes. Initially I couldn't connect from node 1 --sqlplus sys/password@prod2 as sysdba. That is now resolved. I ran the below command from NODE1, (which has the backup directory -/backup) and the archivelog backup proceeded without the numerous error I was having.

RMAN> RUN
2> {ALLOCATE CHANNEL c1 DEVICE TYPE DISK FORMAT '/backup/prod/backup_db/%U' MAXPIECESIZE 2G CONNECT 'sys/oracle@prod1';
3> ALLOCATE CHANNEL c2 DEVICE TYPE DISK FORMAT '/backup/prod/backup_db/%U' MAXPIECESIZE 2G CONNECT 'sys/oracle@prod2';
4> backup (archivelog all);

The "/backup/prod/backup_db” directory is located on node1. Does this mean node2 is unable to write to that directory? I guess I have to make it visible from node2. I will await your reply before I proceed with such a thing.

Thanks for helping and being patience.

Check permissions and double check weather the directory exists?

The directory exist on node1. Does it have to be on node2 or need to be visible? I am backing up to the backup directory on node1. What permission you referring to? Here is the direcory as it exist on node1:

drwxr-xr-x 12 oracle dba 4096 Oct 16 14:01 backup

Is it on local machine or shared storage?
If not on shared storage then create it on node 2 and then try again.

It is on a shared storage - SAN. here are more detail:

backupvg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
loglv06 jfs2log 1 1 1 open/syncd N/A
feelv00 jfs2 4264 4264 10 open/syncd /backup

I am wondering how to make this visible to node2...

You mentioned above that /backup/prod/backup_db/ exists only on node1 ? Is it local to node1 or is it actually shared ?

If you have shared storage where you can create the directory, that would be your best bet. Is your shared storage RAW ?

I said local because the directory is not listed when you cd / in node 2. Unlike node1 (cd /---will show it to you). Ebrian has been very helpful so far. I beleive my current problem might be more of a UNIX, but since I don't have a UNIX admin I will have to work on getting it resolve.

The mount point /backup does not seem to be on a shared disk. You could always share it out on node1 and mount it on node2 as (/backup) so that it will have the same name as on node1 (/backup).

Hi,
Thanks for the response. I am working to get the /backup shared. I don't have a Unix Admin--so when I can that done I will report to you/forum.

Thanks again

Good afternoono,

I got a successful archive log backup today. As, Ebrain recommended I made the /backup directory "share" and mounted it on node2. Both nodes can now see the backup "to" location.

Thanks a million to"Senior member", Ebrain for the help. I couldn't have gone pass this stage without your help. I can now relax knowing that I am backing up the archivelog.

Again, thanx.
