Recover Database from ORA-00333: redo log read error

I got the above error when i start My DB.
I followed the below steps to recover this.

SQL> startup
ORACLE instance started.
Total System Global Area ***** bytes
Fixed Size               ***** bytes
Variable Size            ***** bytes
Database Buffers         ***** bytes
Redo Buffers             ***** bytes
Database mounted.
 
 ORA-00333: redo log read error block *Number* count *Number*

================================================================================

Step 1: Since the DB is in mount mode, We can query v$log & v$logfile to identify the status of log file group and their member.

 SQL> select l.status, member from v$logfile inner join v$log l using (group#); 
 STATUS  MEMBER
 ------------- --------------------------------------
 CURRENT /oracle/fast_recovery_area/redo01.log
 INACTIVE /oracle/fast_recovery_area/redo02.log
 INACTIVE /oracle/fast_recovery_area/redo03.log






 
Step 2: Recover the database using ackup controlfile.

 SQL> recover database using backup controlfile;
ORA-00279: change  generated at  needed for thread 1
ORA-00289: suggestion : /oracle/fast_recovery_area/archivelog/o1_mf_1_634_%u_.arc
ORA-00280: change  for thread 1 is in sequence #
Specify log: {=suggested | filename | AUTO | CANCEL}







Step3: Give 'CURRENT' log file member along with location as input. If it does not work give other log file members along with location in input prompt. In our case we give 
/oracle/fast_recovery_area/redo01.log

Scheduled task won't run .bat file 2008R2

In our production environments, i scheduled a task to start some programs which is a BAT file in Windows Server 2008 R2.

If i double click the .bat file, it started. But from scheduled task, it is not starting. Although i select the task and try to run task manually , it is not starting.

Solution 

 Fill in the "Start In (Optional)" field. There you need to enter the path of .BAT file.

Go to task's properties, Actions, Edit and put the path to BAT filr.

Ex: E:\MUBASHER-IT\ANBI\Documents\

No need to put double quotes.

Schedule a CRON Job in HP-UX

Few days back i have a problem to schedule a cron job in HP-UX to run a .sh script.
Cron is staring exactly on the scheduled time and the particular .sh script also calling from the cron job.
But that component is not starts.

This start.sh script is as follows.

/usr/java/jre1.5.0_22/bin/java -server -Xms512m -Xmx1024m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=90000 -Dsun.rmi.dgc.server.gcInterval=90000 -Djavax.net.ssl.keyStore=keystore -Djavax.net.ssl.keyStorePassword=password -jar lib/DBC.jar> nohup_dbc.out &


Solution

What i did was, i created another script start-cron.cron file which as follows.

 "cd /<File path to start.sh>
  sleep 2
  ./start.sh
  "
and save as .cron.
Change the permission as 777

Then i call the start-cron.cron  file in the CRON job scheduler.
Then the component was started.

Websphere Application server-Transaction across two base servers fails

 I found that this is happening because of  global security enabled default behavior is for transaction protocol messages, e.g. prepare, commit, rollback to be secured. This prevents malicious completion of global transactions.

What we Did

1) Global transaction on WAS requires the two servers to "trust" each other. I solved the problem by importing server A's LTPA key into server B and vice-versa.

2) If you run in an environment where security is not a concern, or the servers are secured by another means, this behavior can be disabled by unchecking the Enable protocol security check box on the transaction
service panel in the admin console
