The core dump configuration for your system is:
A user is running a process in the global zone and the process crashes. The process information is:
User1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash
The server host name is: zeus
What will the per-process core file be named?
Note the first line:
global core file pattern: /globalcore/core.%f.%p
The program name is bash
The runtime process ID is 2663
Note: By default, the global core dump is disabled. You need to use thecoreadmcommand with the-e globaloption to enable it. The-goption causes the command to append the program name(%f)and the runtime process ID(%p)to the core file name.
You need to migrate a UFS file system named /production_ufs to a ZFS file system named /production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.
Which method allows you to meet both requirements?
1. Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.
2. When the copy is complete, /production_zfs will contain an up-to date copy of /production_ufs
Migrating Data With ZFS Shadow Migration
ZFS shadow migration is a tool you can use to migrate data from an existing file system to a new file system. A shadow file system is created that pulls data from the original source as necessary.
You can use the shadow migration feature to migrate file systems as follows:
* A local or remote ZFS file system to a target ZFS file system
* A local or remote UFS file system to a target ZFS file system
Shadow migration is a process that pulls the data to be migrated:
* Create an empty ZFS file system.
* Set the shadow property on an empty ZFS file system, which is the target (or shadow) file system, to point to the file system to be migrated.
For example:
# zfs create -o shadow=nfs://system/export/home/ufsdata users/home/shadow2
* Data from file system to be migrated is copied over to the shadow file system.
Incorrect answers:
B: lucreate-- create a new boot environment
Note: ZFS is the default root file system.
UFS is a supported legacy file system, but it is not supported as a bootable root file system.
Review the ZFS dataset output that is displayed on your system:
Which four correctly describe the output?
A: + Indicates the file/directory was added in the later dataset
C: R Indicates the file/directory was renamed in the later dataset
E: - Indicates the file/directory was removed in the later dataset
G: M Indicates the file/directory was modified in the later dataset
Note: Identifying ZFS Snapshot Differences (zfs diff)
You can determine ZFS snapshot differences by using the zfs diff command.
The following table summarizes the file or directory changes that are identified by the zfs diff command.
File or Directory Change Identifier
* File or directory is modified or file or directory link changed
M
* File or directory is present in the older snapshot but not in the newer snapshot
---
* File or directory is present in the newer snapshot but not in the older snapshot
+
* File or directory is renamed
R
Which modification needs to be made to the Service Management Facility before you publish a new package to the IPS repository?
pkg/image_root
(astring) The path to the image whose file information will be used as a cache for file data.
Incorrect answers:
A: pkg.depotdis the depot server for the image packaging system. It provides network access to the data contained within a package repository. Clients that do not support direct access to a repository through the file system, or for which network access is the only available or preferred method of transport, typically use the package depot.
B: pkg/readonly(boolean)
Sets whether modifying operations, such as those initiated by pkgsend(1), are disabled. Retrieval operations are still available. This property cannot be true when the pkg/mirror property is true. The default value is true.
C: pkg/writable_root
(astring) The file system path to a directory to which the program has write access. This is used with the-readonlyoption to enable the depot server to create files, such as search indexes, without needing write access to the package information.
You need to set up a local package repository to serve 75 client systems. Multiple clients will being the package repository concurrently and you need to ensure that the local repository performs very well under this heavy load, especially during package intensive operations.
Which option would ensure the best performance of the repository during package-intensive rations by multiple clients?
