1. Siapkan schema untuk repository BO:

CREATE TABLESPACE bodev_data datafile ‘/oradata/datafile/ODBO/bodev.dbf’ size 100M autoextend on next 10M;
create user bodev identified by bodev234 DEFAULT TABLESPACE bodev_data;

2. Masukkan export variable ke dalam file .bash_profile :

export PATH=/apps/oracle/product/10.2/bin:$PATH
export ORACLE_HOME=/apps/oracle/product/10.2
export ORACLE_SID=ODBO
export LD_LIBRARY_PATH=/apps/oracle/product/10.2/lib32:$LD_LIBRARY_PATH

3. Masukkan local ke dalam file .bash_profile :

export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

4. Cek locale :

201 #> locale
LANG=UTF-8
LC_CTYPE=”en_US.UTF-8″
LC_NUMERIC=”en_US.UTF-8″
LC_TIME=”en_US.UTF-8″
LC_COLLATE=”en_US.UTF-8″
LC_MONETARY=”en_US.UTF-8″
LC_MESSAGES=”en_US.UTF-8″
LC_ALL=en_US.UTF-8

Kalau source dicopy langsung dari CD, beri privileges untuk execution :

di atas dir BO :
chmod -R +x *

This is a test setup and to get maximum RAM availability, I have 3 data nodes and 1 Management node with replication factor of 1. The solutions provided are the ones which helped me.

1. ERROR 1297 (HY000) at line 1872: Got temporary error 410 ‘REDO log files overloaded, consult online manual (decrease TimeBetweenLocalCheckpoints, and|or incre’ from NDBCLUSTER

Solution : Modify / Add parameter TimeBetweenLocalCheckpoints in your config.ini.
Default value = 20
Changed it to TimeBetweenLocalCheckpoints =6
Setting TimeBetweenLocalCheckpoints to 6 or less means that local checkpoints will be executed continuously without pause, independent of the cluster’s workload.

2. ERROR 1297 (HY000) at line 1443: Got temporary error 1220 ‘REDO log files overloaded, consult online manual (increase FragmentLogFileSize)’ from NDBCLUSTER

Solution: Modify / Add parameter FragmentLogFileSize in your config.ini.
Default value = 16M
Changed it to FragmentLogFileSize=256M
Setting this parameter allows you to control directly the size of the redo log files. This can be useful in situations when MySQL Cluster is operating under a high load and it is unable to close fragment log files quickly enough before attempting to open new ones. Increasing the size of the fragment log files gives the cluster more time before having to open each new fragment log file.

3. ERROR 1297 (HY000) at line 1826: Got temporary error 1221 ‘REDO buffers overloaded, consult online manual (increase RedoBuffer)’ from NDBCLUSTER

Solution: Modify / Add parameter RedoBuffer in your config.ini.
Default value = 8M
Changed5 it to RedoBuffer=128M
All update activities also need to be logged. The REDO log makes it possible to replay these updates whenever the system is restarted. RedoBuffer sets the size of the buffer in which REDO log is written.

4. ERROR 1297 (HY000) at line 7064: Got temporary error 233 ‘Out of operation records in transaction coordinator (increase MaxNoOfConcurrentOperations)’ from NDBCLUSTER

Solution: Modify / Add parameter MaxNoOfConcurrentOperations in your config.ini
Default value=32K
Changed it to MaxNoOfConcurrentOperations=1M
It is a good idea to adjust the value of this parameter according to the size and number of transactions.

5. ERROR 1114 (HY000) at line 8820: The table ‘table_1′ is full

Solution: Modify the parameter DataMemory in your config.ini
Default value: 80M
Changed it to DataMemory=14G
This parameter defines the amount of space (in bytes) available for storing database records. The entire amount specified by this value is allocated in memory., so it is extremely important that the machine has sufficient physical memory to accommodate it.
The memory allocated by DataMemory is used to store both the actual records and indexes. There is a 16-byte overhead on each record; an additional amount for each record is incurred because it is stored in a 32KB page with 128 byte page overhead. There is also a small amount of wastage per page due to the fact that each record is stored in only one page.

6. ERROR 1205 (HY000) at line 10208: Lock wait timeout exceeded; try restarting transaction

Solution: Add / modify the parameter TransactionDeadlockDetectionTimeout in config.ini
Default value = 1200 milliseconds
Changed the value to TransactionDeadlockDetectionTimeout=15000
The timeout parameter states how long the transaction coordinator waits for the query execution by another node before aborting the transaction and is important for both node failure handling and deadlock detection.

7. ERROR 1118 (42000) at line 661: Row size too large. The maximum row size for the used table type, not counting BLOBs, is 8052. You have to change some columns to TEXT or BLOBs

Solution: This error is generally due to the know limitation in MySQL Cluster 5.1.
“The maximum permitted size of any one row is 8KB.” .
The work around for this is modify the table schema so that large varchar values are changed to text

8. ERROR 1005 (HY000): Can’t create table ‘DB1.Table_5′ (errno: 136)

Solution: Errno: 136 refers to index file being full. Parameter that can be modified here is MaxNoOfOrderedIndexes.
Default Value=128. Change it to something higher based on the size mentioned by running ndb_size.pl. In my case it is 263.

Following are a few of the most popular and useful commands used in unix operating system wildcard characters *

The * wildcard character substitutes for one or more characters in a filename. For instance, to list all the files in your directory that end with .c, enter the command

ls *.c

? (question mark) serves as  wildcard character for any one character in a filename. For instance, if you have files named prog1, prog2, prog3, andprog3 in your directory, the Unix command:

ls prog?

-u is userid , if not specified system takes highest available .

-g group id should be existing in /etc/group , if not specified other or user is assigned.

-d home directory , default is to use user as the directory name under the home directory.

loginname – new login name to be created .

#useradd testlogin will create a user by the name ‘testlogin’ with all default values . password Change passwd  <user> alias (csh/tcsh) – Create command alias name1 name2 alias (ksh/bash) – Create alias command alias name1=”name2″ alias – Remove alias unalias name1[na2...] printer Output file f to line printer lp -d printer file System  Status Display disk quota quota Print date & time date List logged in users who Display current user whoami Output user information finger  [username] Display recent commands history Environment Variable set set command alone displays the environment variables, it is used to set options in ksh like set -o vi export export variable ,  export  makes variable visible in sub shells. Set environment  variable (csh/tcsh)  to value v sentenv name v Set environment  variable (ksh/bash)  to value v export name=v example :  export TERM=vt100 Connectivity Connecting to a  remote host $telnet hostname/ip address or  $telnetTelnet brings up the login prompt of remote host and  expects you to enter your user name & password .Without argument it enters command mode (telnet>) and accepts command listed by ? at telnet> prompt.
Communication is not encrypted between two hosts. Securely connecting to a remote host

ssh  username@hostname  or ssh -l username hostname

Depending on ssh setting for your account you may or may not be asked a password to login. Your login/passwd will be same login password as you would use with telnet connection.

Communication is encrypted between two hosts so if someone intercepts your communication he will not be able to use it.

ftp hostname

ftp expects you to enter  your username/passwd or if it is ftp only account it will require ftp account password .

put , mput (multipleput) command is used to transfer files to remote host.

get , mget (multipleput) command is used to transfer files from remote host.

ftp allows some limited number of commands to be executed at ftp> prompt & summary of ftp command can be found by using ? at ftp>  prompt

ping hostname

If you can ping a host the host is reachable from the machine that you are using .

Router/firewall configuration may prevent ping to succeed .

tar tvf filename.tar —  View the table of content of a tar archive

tar xvf filename.tar — Extract content of a tar archive

tar cvf filename.tar file1 file2  file3 — Create a tar archive called filename.tar using file1, file2,file3 .

tar can’t copy the special files , device files .Not suitable for taking root backup.

cpio is mostly used in conjunction with other commands to generate a list of files to be copied :
#ls | cpio -o > /dev/rmt/c0t0d0 — Copy the contents of a directory into a tape archive:
#find . -depth -print | cpio -pd newdir — copy entire directory to other place:
#find . -cpio /dev/rmt/c0t0d0 — Copy files in current directory to a tape

cpio can copy special files and hence useful in taking root backup containing device file.

Find  command is used to find the files , directories and to run commands on the list of files thus generated .By default, find does not follow symbolic links.

find . -name *.log -print — Simple find to list log files

find . -name ‘*.log’ -exec rm  {} \; — Simple find to find log files and delete them .

find accepts a long list of options to find the files based on different parameters such as create time , modified time , of certain size etc. Please refer to man find for more option.

Unix commands forms the building blocks of unix administartion and are needed for administration or simply work in unix environment . If  you are learning unix or are working in unix environment it will be worthwhile that you have good system administration books which can help you to explore full potential of your working environment.

Following books available for online buying from Amazon.com . You should have following two books in your bookshelf  for ready reference  if you are involved in Unix system administration  .

1. Crontab
____________
You can execute crontab if your name appears in the file /usr/lib/cron/cron.allow. If that file does not exist, you can use
crontab if your name does not appear in the file /usr/lib/cron/cron.deny.
If only cron.deny exists and is empty, all users can use crontab. If neither file exists, only the root user can use crontab. The allow/deny files consist of one user name per line.

2. Crontab
__________
export EDITOR=vi ;to specify a editor to open crontab file.

crontab -e     Edit your crontab file, or create one if it doesn’t already exist.
crontab -l      Display your crontab file.
crontab -r      Remove your crontab file.
crontab -v      Display the last time you edited your crontab file. (This option is only available on a few systems.)

3. 
___________
Crontab syntax :-
A crontab file has five fields for specifying day , date and time  followed by the command to be run at that interval.

*     *   *   *    *  command to be executed -     -    -    -    - |     |     |     |     | |     |     |     |     +—– day of week (0 – 6) (Sunday=0) |     |     |     +——- month (1 – 12) |     |     +——— day of month (1 – 31) |     +———– hour (0 – 23) +————- min (0 – 59)

* in the value field above means all legal values as in braces for that column.
The value column can have a * or a list of elements separated by commas. An element is either a number in the ranges shown above or two numbers in the range separated by a hyphen (meaning an inclusive range).

Note: The specification of days can be made in two fields: month day and weekday. If both are specified in an entry, they are cumulative meaning both of the entries will get executed .

4. Crontab
_______

A line in crontab file like below  removes the tmp files from /home/someuser/tmp each day at 6:30 PM.

30     18     *     *     *         rm /home/someuser/tmp/*

Changing the parameter values as below will cause this command to run at different time schedule below :

min	hour	day/month	month	day/week	Execution time
30	0	1	1,6,12	*	– 00:30 Hrs  on 1st of Jan, June & Dec.
:
0	20	*	10	1-5	–8.00 PM every weekday (Mon-Fri) only in Oct.
:
0	0	1,10,15	*	*	– midnight on 1st ,10th & 15th of month
:
5,10	0	10	*	1	– At 12.05,12.10 every Monday & on 10th of every month
:

Note : If you inadvertently enter the crontab command with no argument(s), do not attempt to get out with Control-d. This removes all entries in your crontab file. Instead, exit with Control-c.

5. Crontab
___________
cron invokes the command from the user’s HOME directory with the shell, (/usr/bin/sh).
cron supplies a default environment for every shell, defining:
HOME=user’s-home-directory
LOGNAME=user’s-login-id
PATH=/usr/bin:/usr/sbin:.
SHELL=/usr/bin/sh

Users who desire to have their .profile executed must explicitly do so in the crontab entry or in a script called by the entry.

6.
____________

By default cron jobs sends a email to the user account executing the cronjob. If this is not needed put the following command At the end of the cron job line .

>/dev/null 2>&1

7. 
________________

To collect the cron execution execution log in a file :

30 18  *    *   *    rm /home/someuser/tmp/* > /home/someuser/cronlogs/clean_tmp_dir.log

The first error you will probably run into is:
ERROR: The configuration file now needs a secret passphrase (blowfish_secret)

This can be resolved by copying the sample configuration file to the correct name and making a small modification to it. From the phpMyAdmin directory do the following.

cp -p config.sample.inc.php config.inc.php

You will then need to edit the file with your favorite editor (mine being vi) and add a blowfish_secret phrase to line 17 like the below.

$cfg['blowfish_secret'] = ‘BLOWFISH PASSWORD HERE’; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

After you do this visit your-url/phpadmin-directory where if you don’t have mcrypt and mbstrong installed you will see two more errors. There are easy to resolve by following the directions below.

ERROR: Cannot load mcrypt extension. Please check your PHP configuration.
This is easily resolved by installing php-mcrypt using the bellow command on CentOS.

yum install php-mcrypt
===================================================================
bwt yg make windows =

http://files.edin.dk/php/win32/mcrypt/

1. put libmcrypt.dll in windows system32 folder
2. make sure php_mcrypt.dll is in php extension directory
3. make sure php.ini directive extension_dir points to the right path
4. uncomment ;extension=php_mcrypt.dll from php.ini
5. restart webserver (kalo perlu ajja) ... thats it, should work now

ERROR: The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.
This error may not be seen until logging into phpMyAdmin but is also easily resolved by installing mbstring using the below command.

yum install php-mbstring

$ mysqldump -u user -p db-name > db-name.out

Copy db-name.out file using sftp/ssh to remote MySQL server:

$ scp db-name.out user@remote.box.com:/backup

Restore database at remote server (login over ssh):

$ mysql -u user -p db-name < db-name.out

How do I copy a MySQL database from one computer/server to another?

Short answer is you can copy database from one computer/server to another using ssh or mysql client.

You can run all the above 3 commands in one pass using mysqldump and mysql commands (insecure method, use only if you are using VPN or trust your network):

$ mysqldump db-name | mysql -h remote.box.com db-name

Use ssh if you don’t have direct access to remote mysql server (secure method):

$ mysqldump db-name | ssh user@remote.box.com mysql db-name

You can just copy table called foo to remote database (and remote mysql server remote.box.com) called bar using same syntax:

$ mysqldump db-name foo | ssh user@remote.box.com mysql bar

This will not just save your time but you can impress your friend too . Almost all commands can be run using pipes under UNIX/Linux oses.

1. Stopping the DB2 administration server
   • Log in as the DB2 administration server owner
   • Stop the DB2 administration server by entering the db2admin stop command.
   • Remove the DAS by entering the following command: DB2DIR/instance/dasdrop
2. Stopping all DB2 instances
   • Log in as a user with root authority
   • To obtain a list of the names of all DB2 instances associated with your current DB2 copy, enter the following command: DB2DIR/bin/db2ilist, where DB2DIR is e.g. /opt/IBM/db2/V8.1
   • Log out
   • Log back in as the owner of the instance you want to stop
   • Stop the DB2 database manager by entering the db2stop force command
   • Confirm that the instance is stopped by entering the db2 terminate command
   • Repeat these steps for each instance
3. Removing DB2 instances
   • Log in as a user with root authority
   • Remove the instance by entering the following command: DB2DIR/instance/db2idrop InstName
     , where DB2DIR is e.g. /opt/IBM/db2/V8.1
   • Repeat these steps for each instance
4. Removing DB2 products using the db2_deinstall
   • Log in as a user with root authority
   • Run the db2_deinstall -a command from the DB2DIR/install, where DB2DIR is e.g. /opt/IBM/db2/V8.1

Note: The db2idrop command removes the instance entry from the list of instances and removes the INSTHOME/sqllib directory, where INSTHOME is the home directory of the instance and where InstName is the login name of the instance. If you are storing any files in /sqllib directory, these files will be removed by this action. If you still need these files, you must make a copy of them before dropping the instance.

Cognos “Quick” Start Installation and Configuration Guide transcript

Error: Cognos Configuration error creating new data store

Database connection failed
Content Manager failed to start because it could not load driver “oracle.jdbc.driver.OracleDriver”

This went away when I copied classes12.jar from ORACLE_HOME\jdbc\lib to c8_location\webapps\p2pd\WEB-INF\lib

Error: Cognos Configuration error creating new data store #2

Content Manager is unable to initialize the content store by using the initialization file “C:\Program Files\cognos\c8\configuration\schemas\content\oracle\dbInitTest_oracle.sql”

It appears the Schema user has insufficient privileges. I have given the following:

Roles

• Connect

System Privileges

• Alter any procedure, sequence, table, trigger
• Create any procedure, sequence, table, trigger, view
• Delete any table
• Drop any procedure, sequence, table, trigger, view
• Insert any table
• Update any table

When I execute the script in SqlPlus the error is ORA-01950: no privileges on tablespace ‘X’. Apparently this means no quota has been allocated for this user.

I attempted to grant unlimited quota on all tablespaces but got an error ORA-30041: Cannot grant quota on the tablespace. I forgot that the temp table space doesn’t have a quota, so I was a bit more specific in my selection.

Error: Cognos Configuration error creating new data store #3

Content Manager cannot start because the database character set for the content store is not supported. Before you restart Content Manager, you may need to recreate the content store database or clean it using dbClean_*.sql.

Following the instructions regarding character set, I found NLS_NCHAR_CHARACTERSET = AL16UTF16. Unfortunately this doesn’t appear to be sufficient. SELECT NLS_CHARACTERSET FROM NLS_DATABASE_PARAMETERS returned WE8MSWIN1252. Some guidance on changing character set is that it’s safest to export-create new db-import.

My steps for export are:

• Bring up Database Control
• Select Maintenance tab
• Select Export to Export Files
• Select Database and enter OS admin user and password
• (Create the export folder before doing the next step)
• Create Directory Object, enter name and folder path and select OK
• Select the name of the newly created dir object from Directory Object dropdown and select Next
• Select the dir object again and select Next
• Enter a job name and description and select Next
• Select Submit

The job kicked off but produced some errors saying it couldn’t find the export directory object. Makes no sense to me, I thought I would just try and sneak on by.

I created a new instance with Database Configuration Assistant using character set AL32UTF8 and tried to import the export files into it but I hit a lot of errors.

I decided to use a separate instance just for Cognos. Phew, I could finally connect ok to the Content Database.

Cognos 8 Cryptographic Services

Copied c8_location\bin\jre\version\lib\ext\bcprov-jdk13-125.jar to java_home\lib\ext. I have no idea if this has to be done but I did it anyway.

Starting the Service

Selected Root node in Cognos Configuration and Action:Test. All came back good except mail server which I don’t care about for the moment. Selected Action:Start which was also successful.

Getting the web server to respond

Created virtual directory for cognos8 at c8_location\. Worked through the IE settings and browsed to http://localhost/cognos8. 404 Page not found. Trawled around on web and found that I could Allow All Unknown CGI Extensions in IIS Web Extensions. This time I got 403 Not authorised to view this page.

Figured out that I didn’t read the instructions correctly – there are 2 nested virtual directories.

• cognos8 points to c8_location\webcontent
• cgi-bin points to c8_location\cgi-bin. Created by right-clicking the previously created cognos8 virtual directory

At last it works! The Framework Manager install was straightforward after this.
