Compling ANTLR 2.7.7 on CentOS 6

What is ANTLR?

ANTLR, ANother Tool for Language Recognition, (formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing Java, C#, C++, or Python actions. ANTLR provides excellent support for tree construction, tree walking, and translation. There are

Step 1: Download ANTLR 2.7.7

Step 2: Untar ANTLR-2.7.7

# tar -zxvf antlr-2.7.7
# antlr-2.7.7

Step 3: For RHEL and CentOS, edit the source file /root/antlr-2.7.7/lib/cpp/antlr/CharScanner.hpp

# vim /root/antlr-2.7.7/lib/cpp/antlr/CharScanner.hpp

Add the following into the CharScanner.hpp file
antlr

Step 4: Compile the antlr-2.7.7

# ./configure --prefix=/usr/local/antlr2.7.7 --disable-examples
# make -j 8
# make install

Platform LSF – Controlling Hosts

1. Closing a Host

# badmin hclose hostid
Close hostid ...... done

2. Opening a Host

# badmin hopen hostid
Open hostid ...... done

3. Log a comment when closing or opening a host

# badmin hopen -C "Re-Provisioned" hostA
# badmin hclose -C "Weekly backup" hostB

The comment text Weekly backup is recorded in lsb.events. If you close or open a host group, each host group member displays with the same comment string.

Platform LSF – Working with Hosts (bhost, lsload, lsmon)

Host status

Host status describes the ability of a host to accept and run batch jobs in terms of daemon states, load levels, and administrative controls. The bhosts and lsload commands display host status.

 

1. bhosts
Displays the current status of the host

STATUS DESCRIPTION
ok  Host is available to accept and run new batch jobs
unavail  Host is down, or LIM and sbatchd are unreachable.
unreach  LIM is running but sbatchd is unreachable.
closed  Host will not accept new jobs. Use bhosts -l to display the reasons.
unlicensed Host does not have a valid license.

 

2. bhosts -l
Displays the closed reasons. A closed host does not accept new batch jobs:

STATUS DESCRIPTION
ok Host is available to accept and run batch jobs and remote tasks.
-ok LIM is running but RES is unreachable.
busy Does not affect batch jobs, only used for remote task placement (i.e., lsrun). The value of a load index exceeded a threshold (configured in lsf.cluster.cluster_name, displayed by lshosts -l). Indices that exceed thresholds are identified with an asterisk (*).
lockW Does not affect batch jobs, only used for remote task placement (i.e., lsrun). Host is locked by a run window (configured in lsf.cluster.cluster_name, displayed by lshosts -l).
lockU Will not accept new batch jobs or remote tasks. An LSF administrator or root explicitly locked the host using lsadmin limlock, or an exclusive batch job (bsub -x) is running on the host. Running jobs are not affected. Use lsadmin limunlock to unlock LIM on the local host.
unavail Host is down, or LIM is unavailable.

RHEV 3.4 – Explanation of Settings in the New Data Center and Edit Data Center Windows

The table below describes the settings of a data center as displayed in the New Data Center and Edit Data Center windows. Invalid entries are outlined in orange when you click OK, prohibiting the changes being accepted. In addition, field prompts indicate the expected values or range of values.

Details on each items

Field
Description/Action
Name
The name of the data center. This text field has a 40-character limit and must be a unique name with any combination of uppercase and lowercase letters, numbers, hyphens, and underscores.
Description
 The description of the data center. This field is recommended but not mandatory.
Type
The storage type. Choose one of the following:
  • Shared
  • Local
The type of data domain dictates the type of the data center and cannot be changed after creation without significant disruption. Multiple types of storage domains (iSCSI, NFS, FC, POSIX, and Gluster) can be added to the same data center, though local and shared domains cannot be mixed.
Compatibility Version
The version of Red Hat Enterprise Virtualization. Choose one of the following:
  • 3.0
  • 3.1
  • 3.2
  • 3.3
  • 3.4

After upgrading the Red Hat Enterprise Virtualization Manager, the hosts, clusters and data centers may still be in the earlier version. Ensure that you have upgraded all the hosts, then the clusters, before you upgrade the Compatibility Level of the data center.
Quota Mode
 Quota is a resource limitation tool provided with Red Hat Enterprise Virtualization. Choose one of:

  • Disabled: Select if you do not want to implement Quota
  • Audit: Select if you want to edit the Quota settings
  • Enforced: Select to implement Quota
