HI

We have successfully restore from TSM but when we perform rollback got error as below.

existing database does not match the database name "GPB" of the backup image.

The target database will be overwritten by the backup version.

db2 rollforward db GQB query status

Input database alias = GQB

Number of nodes have returned status = 1

Node number = 0

Rollforward status = DB working

Hi Marc,

I tried the same and got the below error :

SQL1276N Database "M03" cannot be brought out of rollforward pending state

until roll-forward has passed a point in time greater than or equal to

"2011-06-18-04.50.00.000000 UTC", because node "0" contains information later

than the specified time.

Can you please advise ?

thanks,

Raj

Hi it's look like db2 did not find the log S0130978.LOG under /db2/GQB/log_dir. If the log file is not under this directory, you need to restore the log file.

This is an exemple using brrestore with TSM :

Step 1 : db2 rollforward db GQB query status and note "Next log file to be read"

Step 2 : cd /db2/GQB/log_dir *To dump the log under this directory

Step 3 : brrestore -q "NODE" -out -sid GQB *To query the log file available

Step 4 : brrestore -ex "S0130978.LOG*" -d adsm -sid GQB

Step 5 : Rename the log file with the appropriate name ie: S0130978.LOG and make sure the file is under /db2/GQB/log_dir

Step 6 : db2 "rollforward db GQB stop OVERFLOW LOG PATH (/db2/GQB/log_dir)"

CHeck that !

Hi Marc,

You are correct, the appropriate logs are not found in /db2/M03/log_dir

But, It seems we dont have this "brrestore" command :

db2m03> man -k brrestore

brrestore: Cannot find matching entry.

Is there any other way to retrieve the logs from TSM ?

Thanks,

Raj

Hi Marc,

Please find output as below

db2 "rollforward db GQB stop OVERFLOW LOG PATH (/db2/GQB/log_dir)"

SQL1276N Database "GQB" cannot be brought out of rollforward pending state

until roll-forward has passed a point in time greater than or equal to

"2011-07-10-08.06.59.000000 UTC", because node "0" contains information later

than the specified time.

db2 rollforward db GQB to 2011-07-10-08.06.59.000000

SQL1274N The database "GQB" requires roll-forward recovery and the

point-in-time must be to the end of logs.

db2 rollforward db GQB to end of logs

SQL4970N Roll-forward recovery on database "GQB" cannot reach the specified

stop point (end-of-log or point-in-time) because of missing or corrupted log

file(s) on database partition(s) "0". Roll-forward recovery processing has

halted on log file "S0131143.LOG".

db2 rollforward db GQB query status

Rollforward Status

Input database alias = GQB

Number of nodes have returned status = 1

Node number = 0

Rollforward status = DB working

Next log file to be read = S0131143.LOG

Log files processed = -

Last committed transaction = 2011-07-10-08.06.59.000000 UTC

But this file S0131143.LOG exist in /db2/GQB/log_dir/NODE0000.

Hi Kumar if the log exist point the overflow log path on this directory

db2 "rollforward db GQB stop OVERFLOW LOG PATH (/db2/GQB/log_dir/NODE0000

Hi you need to use db2adutl in this case :

Step 1 : db2 rollforward db GQB query status and note "Next log file to be read"

Step 2 : cd /db2/GQB/log_dir *To dump the log under this directory

Step 3 : db2adutl query logs

Step 4 : db2adutl extract logs between S0084324.LOG AND S0084325.LOG * The LOG sequence you want to retrieve

Step 5 : Rename the log file with the appropriate name ie: S0130978.LOG and make sure the file is under /db2/GQB/log_dir

Step 6 : db2 "rollforward db GQB stop OVERFLOW LOG PATH (/db2/GQB/log_dir)"

thanks a lot Marc, that worked.

but I have another issue now

db2m03> db2 rollforward db M03 to end of logs

SQL1268N Roll-forward recovery stopped due to error "SQL2033" while

retrieving log file "S0059505.LOG" for database "M03" on node "0".

Please help me how to bring the database to a consistent state ASAP.

Thanks in advance,

Dear Marc,

thanks again for the help

I just extracted the log(s) it specified as missing...and then gave a rollforward to end of logs

i believe its success now.

db2m03> db2 rollforward db M03 query status

Rollforward Status

Input database alias = M03

Number of nodes have returned status = 1

Node number = 0

Rollforward status = not pending

Next log file to be read =

Log files processed = S0059488.LOG - S0059506.LOG

Last committed transaction = 2011-06-18-07.02.03.000000 UTC

Please correct if anythign is wrong...
