Increase Transaction timeout in SOA Server

Posted on by Osama Mustafa in Fusion Middleware
I received the below error in soa_server1 :-

Transaction Rolledback.: weblogic.transaction.internal.TimedOutException: Transaction timed out after 603 seconds BEA1-3FB6FB464035C13E3227 at 

From the above error, transaction timeout should be increased regarding to heavy transaction on soa server.

to do this follow the following steps :-

access weblogic console –> Deployment –> and search for Soa_infra. ( expand it)

Check the below EJBS services and click on it configuration tab :-
BPELActivityManagerBean
BPELEngineBean
BPELInstanceManagerBean
BPELProcessManagerBean
BPELServerManagerBean

If this not working on you have to increase transaction timeout for JTA, Access Weblogic Console select Services > JTA

SOA_SERVER ( Managed Server ) Take too Long time to Start/Restart

Posted on by Osama Mustafa in Fusion Middleware
On the weblogic console when trying to start managed Server it’s take too long time to start in my case it’s SOA_SERVER, almost 25 min only to start, which is not correct . to avoid this problem you need to follow the below steps simple but effective :-

Under Java Home ( That Used by Weblogic ) :-

cd /u01/app/fmw/jdk/jre/lib/security 

There’s file called Java.Security 

Edit this File using any Editor ( vi for example ).

Search for the following line :-

securerandom.source=file:/dev/urandom

And Change it to :-

securerandom.source=file:/dev/./urandom

Or Another way add the below line to startup script in weblogic :-

-Djava.security.egd=file:/dev/./urandom

Hope this will solve your problem.

Thank you

As you see from the error,The OraclePWD connection attribute is not specified. which mean caching will not be enabled till you are set OraclePWD parameter , to do this reconnect with the following connection :-

connect “dsn=tt_orcldwh;uid=cacheadm;OraclePWD=cacheadm”;

Run your command again

Change OHS Port On Linux to Work on 80

Posted on by Osama Mustafa in Fusion Middleware

Operating system : Oracle Linux 6.4
Oracle WebTier OHS 11.1.1.7

if you want to configure OHS ( WT ) to work on port 80 ( http ) avoiding insert Port.

For Example :

OHS default Port is 7777, if you want to leave it like this any call for the server should be like this :

http://:7777/console  

But if you are using port 80 you have to do the below :

http:///console 

But on Linux if you need to use port 80 you have to be root, to do this follow the below step :

  • As root user :

[root@TST-WT1 bin]# pwd
/u01/fmw/Oracle_WT1/ohs/bin 

[root@TST-WT1 bin]# chown root .apachectl
[root@TST-WT1 bin]# chmod 6750 .apachectl

  • As Oracle User

[oracle@TST-WT1 ~]$ cd /u01/fmw/admin/config/OHS/ohs1/ 

[oracle@SCADNP-WT1 ohs1]$ ls http*
 httpd.conf      

  • Edit the file using any Editor and modify Listen from 7777 to 80
  • Restart OHS using opmnctl command.

Configure Linux NFS File System

Posted on by Osama Mustafa in Operating system
NFS : Network File System

Before Start Configure NFS you have to Understand When to use it ? and What is it ?

NFS file system usually read from Source Called Server , If this server goes down, it will not be available for the other resource, From this we understand that i should configure NFS On both Side Server and Client.

Read More About it Here.

Note : 

Server IP : 192.168.1.100
Client IP : 192.168.1.101

In this Blog I will Use NFSV4 

1- You need to install two Package ( as root user )
**nfs-ultis-lib
**portmap ( if you are asking nfs4 this is not needed anymore )

2-  As Root Run the below Command to Start nfs Serivces :

[root@TEST share]# /etc/init.d/nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS quotas:                                       [  OK  ]
Starting NFS mountd:                                      [  OK  ]
Stopping RPC idmapd:                                    [  OK  ]
Starting RPC idmapd:                                      [  OK  ]
Starting NFS daemon:                                     [  OK  ]

3- Create folder under /u01/app/shared , give permission to oracle and chmod 775 
4- on NFS Server ( you will own the folder ) , vi /etc/exports add the below line :

/u01/app/shared [Client-IP] (rw,sync,no_root_squash) 

5- NFS Server is done , Go to NFS Client ( Node 2 )  as root user run the below command :

#/etc/init.d/nfs start
#showmount -e 192.168.1.101

The Output Will be like the below :

Export list for 192.168.1.100:
/u01/app/shared 192.168.1.101

6-On Node 2 ( As Root User ) –> #  mount -t nfs 192.168.1.100:/u01/app/shared/ /u01/app/shared/
7- Check using df -h 

**Remove:-

8- umount /u01/app/shared ( on Node 2 ) 

Important Command :
showmount -e : Shows the available shares on your local machine
exportfs -v : Displays a list of shares files and options on a server

Thank you
