Release Notes
Release 12.1.3.0.0
E56823-01
September 2014
This document contains the release notes for Oracle Database Appliance Kit for WebLogic Server version 12.1.3.0.0. It contains the following sections:
Section 1, "Coherence Configuration Issues in WLS on ODA Configurator"
Section 3, "Configuring a Common NFS Mount Point to be Shared Across all Coherence VMs"
Section 4, "Handling Assign IP Failed Error During Configuration"
Section 5, "Creating a cpu pool with size more than 25 results in error message"
Section 6, "User Roles for Applying Patches differ in WebLogic Server Versions"
Section 7, "Gateway and Netmask on the same subnet as ODA_BASE"
Section 8, "Running Configurator While Doing a Cleanup Not Allowed"
Section 9, "Rebooting Both DOM0 Nodes at the Same Time Can Lead to Bad State"
Section 11, "Oracle Traffic Director Virtual IP Address Is Not Accessible"
Section 12, "Unable to Start JConsole from the WebLogic Virtual Machines"
The Coherence configuration in the WLS on ODA Configurator might cause some issues. Here are the details and the workaround solutions.
When importing an existing configuration, sometimes the Coherence check box on the Domains page is selected and disabled. If you want to disable Coherence, you can go on the Coherence page and use De-select All to disable Coherence.
De-selecting individual domains on the Coherence page might not be possible sometimes. If this happens, use De-select All and re-select the domains on which you want to run Coherence.
On the Domains page, the co-locate with Admin check box may have multiple Managed Servers selected. Make sure that only a single Managed Server is selected (per domain) by de-selecting others. If you are not able to de-select, restart the configurator as having multiple co-located Managed Servers is not supported.
If the configurator causes a stack dump in the console where it is running, the configurator will need to be re-loaded as verification will be broken.
Use this procedure to configure a common NFS mount point to be shared across all the Coherence VMs being configured as it requires at least 20 GB of storage.
Create ACFS on dom1 (ODA_BASE)
As a grid user, start ASMCMD:
# su - grid $ . oraenv ORACLE_SID = [grid] ? ORACLE_HOME = [/home/oracle] ? /u01/app/12.1.0.2/grid The Oracle base has been set to /u01/app/grid $ asmcmd
Create Oracle ASM volume
ASMCMD> volcreate -G data -s 20G volume1
Get the device name:
ASMCMD> volinfo -G data volume1
Diskgroup Name: DATA
Volume Name: VOLUME1
Volume Device: /dev/asm/volume1-234
...
Create FS using device
/sbin/mkfs -t acfs /dev/asm/volume1-234
(Optional) Register FS
/sbin/acfsutil registry -a /dev/asm/volume1-234 /u01/app/acfsmounts/myacfs
You can change the last parameter to a path of your choice
Mount FS (if registered this may have been done automatically)
mkdir -p /u01/app/acfsmounts/myacfs mount -t acfs /dev/asm/volume1-234 /u01/app/acfsmounts/myacfs
You can create the directory anywhere with a name of your choice.
Export ACFS using NFS
Create entries in /etc/exports on the dom1 (ODA_BASE) where the ACFS above was created
# cat /etc/exports /u01/app/acfsmounts/myacfs 192.168.16.64(rw,no_root_squash,fsid=1801) /u01/app/acfsmounts/myacfs 192.168.16.68(rw,no_root_squash,fsid=1802)
Make sure to add one entry per VM that will be mounting the NFS. Use the internal IP of the VM and update the FSID for each entry.
Ensure NFS server will be started on dom1 (ODA_BASE) in case of reboot
# chkconfig --list | grep nfs nfs 0:off 1:off 2:on 3:on 4:on 5:on 6:off nfslock 0:off 1:off 2:off 3:on 4:on 5:on 6:off
Reload the NFS settings for above entries to take effect
# exportfs -a
Verify that NFS is exported
# exportfs -v
...
/u01/app/acfsmounts/myacfs
192.168.16.64(rw,wdelay,no_root_squash,no_subtree_check,fsid=1801,anonuid=65534,anongid=65534)
/u01/app/acfsmounts/myacfs
192.168.16.68(rw,wdelay,no_root_squash,no_subtree_check,fsid=1802,anonuid=65534,anongid=65534)
There may be other entries in the above output. Make sure the entries you added are there.
Mount the NFS on the VMs
Install NFS on all VMs where you will be mounting.
Extract the RPMs bundle and install:
tar -xzvf nfs_rpms.tgz cd nfs rpm -ivh ./*
Mount the NFS:
mkdir -p /mnt/nfs mount <dom1_IP>:/u01/app/acfsmounts/myacfs /mnt/nfs
Make sure you use the internal IP address and paths.
When you do multiple deployments, you may come across the Assign-IP failed error.
Note:
Use the following procedure only during initial deployments as all VM entries are removed.
Delete this file from both dom0:
/opt/oracle/oak/conf/oakvmagentIp.db
Restart agent on both dom0:
Find the agent process ID
ps -ef | grep oak /opt/oracle/oak/bin/oakVmAgent.py
Kill the identified process.
The agent restarts automatically and recreates the above IP file.
Using Oracle Database Appliance for WebLogic Server version 2.9.1 and earlier on ODA X3-2 and X4-2, if you try to create a cpupool with size more than 24, it displays the following error:
OAKERR:8001 OAK Vm Client called with invalid arguemnts:numOfCpus=25
The maxvcpu value is hardware specific. It is 24 in ODA V1, 32 in ODA X3-2 and 48 in ODA X4-2.
Depending on your hardware, enter the following command on ODA_BASE on both the nodes:
cd /opt/oracle/oak/dapters/oakvmclientlib sed -i 's/MAXVCPUS=.*/MAXVCPUS=48/' clientConstants.py
To install the patches, instructions are delivered along with the patches. Note that the user roles for installing patches are different in Oracle WebLogic Server 10.3.6 and Oracle WebLogic Server 12.1.x versions.
Only oracle user with oinstall group privileges can run the OPatch command in Oracle WebLogic Server 12.1.x versions. The root user cannot run the OPatch command. The password for the oracle user is the same as the root user which is used for configuring Oracle WebLogic Server VMs.
Gateway and Netmask for Oracle WebLogic Server and Oracle Traffic Director must be on the same subnet as the ODA_BASE. The configurator will display a warning if you provide invalid values.
On ODA X3-2 and X4-2, there is support for both Eth1 and Eth2 network interfaces:
If Eth1 network is used, the gateway/netmask details entered must be on the same subnet as the Eth1 of ODA_BASE.
If Eth2 network is used, the gateway/netmask details entered must be on the same subnet as the Eth2 of ODA_BASE.
Eth1 and Eth2 can be on different subnets as long as their subnets match with that of ODA_BASE.
On ODA V1, there is support for both Eth1 and Eth4 network interfaces:
If Eth1 network is used, the gateway/netmask details entered must be on the same subnet as the Eth1 of ODA_BASE.
If Eth4 network is used, the gateway/netmask details entered must be on the same subnet as the Eth2 of ODA_BASE.
Eth1 and Eth4 can be on different subnets as long as their subnets match with that of ODA_BASE.
You cannot run the configurator while a cleanup is in process. During cleanup, the state of Oracle Database Appliance will be changing and this might lead to incorrect validation if a resource has not been cleaned up yet.
You cannot run the configurator with an existing deployment if all vCPUs are in use on either dom0. Both dom0s must have at least 1 vCPU available, which can be determined by running oakcli show cpupool -node <0|1> for both nodes. If the output for both nodes includes default-unpinned-pool, you can run the configurator only to create and save a new configuration.
Additionally, do not run provisioning if a deployment already exists.
If you reboot both DOM0 nodes at the same time, oak fails to discover the repository.
Restart oak if you rebooted both nodes at the same time accidentally.
While using JMS and deploying a large number of Managed Servers, the datasource runs out of usable connections to set up Tlogs by the time the final Managed Server comes up.
If you plan to use JMS and deploy a large number of Managed Servers, make sure that the database instance you provide has enough processes. You can increase the number of allowed processes using one of the following methods:
Connect to the running database and increase the number of processes using the following command, and restart the instance:
SQL > alter system set processes=250 scope=spfile;
Increase the value of PROCESSES in the init<SID>.ora file of the instance and restart the instance. You can find the file at this location:
<ORACLE_HOME>/dbs/init<SID>.ora
If you have two ODA boxes on the same Ethernet and you provision the Oracle Database Appliance for WebLogic Server Kit on each box, the Oracle Traffic Director virtual IP address is not accessible.
Use the following commands to delete the existing failover configuration, and then recreate it using a router ID that is not in use in the network:
delete-failover-group --config wlsoda-otd-config --virtual-ip=OTD_virtual_IP
create-failover-group --config=wlsoda-otd-config --virtual-ip=OTD_virtual_IP --primary-node=Node1_IP_address --backup-node=Node2_IP_address --network-prefix-length=network_prefix_length --router-id=unused_router_ID
JConsole cannot be started from the WebLogic VMs. An UnsatisfiedLinkError exception occurs.
Use either of the following workarounds for this issue.
Configure the YUM repository (add http://public-yum.oracle.com/public-yum-el5.repo to the /etc/yum.repos.d directory), and then install the missing RedHat Package Managers (RPMs):
yum install libXext
yum install libXtst
yum install libXi
To use an external JConsole to connect, add the following parameter to the relevant JVM's start arguments:
-Xmanagement:ssl=false,authenticate=false,port=unused_port_number
You can then connect to this JVM remotely through the specified port.
