PRVF-5436 PRVF-9652 Cluster Time Synchronization Services check failed

Image
$GRID_HOME/bin/cluvfy comp clocksync
Cause of the Problem
The problem happened because the time service (such as NTP) is not running or doesn't have slew option set.

Solution of the Problem
The problem happened because time service NTP is not running or doesn't have slew option set.
So, ensure that NTP service is up and running.
Based on the operating system solutions are given below.


1) Linux:

To verify service as root user issue,
# /sbin/service ntpd status
ntpd (pid 4423) is running...

Check process is running or not by.
# ps -ef|grep ntp
ntp 4209 1 0 Mar10 ? 00:00:00 ntpd -u ntp:ntp -p /var/run/ntpd.pid -x

# grep OPTIONS /etc/sysconfig/ntpd
OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid -x"

If NTP service is not started then to start the service issue,
To start the service issue,

# /sbin/service ntpd start

2) Solaris:

To verify the service issue,

# /usr/bin/svcs ntp

Using FAN callouts (relocate a service back)

In Oracle 10g RAC, every time a node/instance/service goes up/down, that event can be trapped and used to make user defined callouts. So every time a state change occurs, a FAN event is posted to ONS immediately. When a node receives an event through ONS, it will asynchronously execute all executables in the server side callouts directory.

There could be lot of applications to using this feature of callouts. For example, when an instance goes down, we all know that services running on that instance are relocated to other available instances. But when that instance comes back up, those relocated services need to be manually put back to their preferred instance. By using FAN callouts, we can automate this task.

1. Go to $ORA_CRS_HOME/racg and create usrco directory on all the nodes. So the server side callout directory would look something like this:
/oracle/product/crs/racg/usrco

2. Place your callout scripts under this dir. This will be called on every state change. You could use any …

Repair Database Corrpution Using 11g New Tools

As Database Administrator you Face Some Issue About The Database Corruption  But In 11g You have Some New Tool Called "data recovery advisor" .


With DRA you check the block corruptions and loss of data files and control files. The GUI feature also available from Enterprise manager.


Lets Start Using This Tool :

Change to Archive Log Mode In Oracle Rac

1. Disable clustering putting cluster_database parameter FALSE.
$export ORACLE_SID=ORCL1
$sqlplus "/ as sysdba"
Check the status of archive mode of the database:

SQL>archive log list
Database log mode              No Archive Mode
Automatic archival             Disabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     407
Current log sequence           408

SQL> alter system set cluster_database=false scope=spfile sid='ORCL1';
2. Shutdown all instances using srvctl utilty
$ srvctl stop database -d cobra
3. Mount tha database using one of the instance:
$ sqlplus "/ as sysdba"


SQL> startup mount
4. Enable archivelog using following command:
SQL> alter database archivelog;

5. Re-enable clustering putting instance parameter cluster_database to TRUE from the current instance:

SQL> alter system set cluster_database=true scope=spfile sid='ORCL1';

6. Shutdown the local instance:

OAS process type = OC4J:Home unable to start

After Trying All The Solutions , Metalink note nothing Works But Never Give up I provide Solution For The
below Error :


Error
--> Process (pid=8337)
time out while waiting for a managed process to start
Log:
/oraas/ias10g/MID/opmn/logs/OC4J~home~default_island~1

Note : Try This Solution After Have been Increase timeout On Opmn.xml


Solution :


1- Create New OC4J instance By

createinstance -instanceName OC4J_instanceName
Enter Password That you want .

2- Check /etc/hosts On you server, Its must Contain
 127.0.0.1 localhost.localdomain localhost 3-group must be change from default_group to your new Group (that you Create it in Step 1 ) .

cd $ORACLE_HOME/opmn/conf/
vi opmn.xml

Search For Default_group (its Default Group in Installation) and Change it to New One
For Example :

You New OC4J_instance_name : test
Default group Should be : test_group
 Search For Default_group and Change it with test_group. 
4-aftre the above steps :

opmnctl stopall
opmnctl startall

ORA-19566 exceeded limit of %s corrupt blocks for file %s

Cause: The user specified limit of allowable corrupt blocks was exceeded while reading the specified datafile for a datafile copy or backup. Action: None. The copy or backup operation fails. The session trace file contains detailed information about which blocks were corrupt.But The Below is Work around : 1)Run DBVerify utility. Have a look at Verify Physical Data Structure For example,$ dbv file=/oradata2/data1/dbase1/system01.dbf Also run this operation for against the all datafiles you suspect which has corrupt block. 2)While taking backup within RUN block specify SET MAXCORRUPT in order to say how many corruption it can handle. I ran dbverify utility and I saw 1 block corrupt each in SYSTEM(1) and SYSAUX(3) datafile. 3)Now backup database with SET MAXCORRUPT option.Syntax : SET MAXCORRUPT FOR DATAFILE File_id For DatabaseFiles to ;SET MAXCORRUPT FOR DATAFILE to ;RMAN> RUN{ 2> SET MAXCORRUPT FOR DATAFILE 1,3 to 1; 3> BACKUP DATABASE; 4> } For data…

FRM-92100 : your connection to the server was interrupted

Cause

NLS_LANG has been set to an invalid value in the environment of the user starting Oracle Forms Services.

Solution

Set NLS_LANG to a valid value like AMERICAN_AMERICA.AR8MSWIN1256 in the default.env file or any custom environment file which is being used.

You can go to regedit and also set the NLS_LANG value to the one mentioned above and check if this resolves the issue. 

 If the Above Solution Doesn't Work For you Try The Below One :

1) FRM-92100 occurs when invoking a new forms session from existing form session, or another URL is invoked from the parent browser window of the forms applet?

To work-around use the applet parameter separateFrame="True". This parameter is set in the static html file or formsweb.cfg

2) If using Oracle Jinitiator, try clearing the Jinitiator JAR or jcache:

For versions 1.3.x.x.x : Control Panel - Jinitiator Control Panel - Cache Tab Page - Clear JAR Cache button

3) If using MS Internet Explorer check that permissions / security …

As We All Know if you need to start/shutdown Oracle Apps you need go $ADMIN_SCRIPT_HOME In R12 Or $CONTEXT_HOME in R11

This Article Explain What These Scripts Do :

adstpall.sh Master script to stop all components/services of middle tier or application tier

adalnctl.sh Script to start / stop apps listener (FNDFS and FNDFS). This listener will file will be in 10.1.2 ORACLE_HOME (i.e. Forms & Reports Home)
listener.ora file will be in $INST_TOP/apps/$CONTEXT_NAME/ora/10.1.2/network/admin directory
