How to create a snapshot?

I have the whole setup up and running for a week now, no problems. I want to create a snapshot of the VM. Do I need to shutdown Oracle and/or the VM to create a snapshot or can I create a snapshot while everything is still running?
Thanks

you can do either one. taking a snapshot while the system is UP requires additional disk space (memory size).. also after you restore from this snapshot, give the VM a few minutes to 'wake up'.. in this version of Workstation you can only have 1 snapshot, meaning that once you take the snapshot you will not be able to go back to the shipped version of the VM other than a reinstall (or you can keep a copy of the directory right after a fresh install). Version 5 of workstation allows multiple snapshot management...

How do I create a Snapshot without testing query?

I'm working in an environment where the connection to the database server is done through a VPN that is sometimes broken and I have to wait for some time until it is restored. Other times, the database server is just down and in maintenance.
In the meantime, I have to work with Director installed in a local virtual machine in my laptop.
So, now I'm trying to develop some EDQ processes when there is no connection to the database, I'm unable to save snapshots because they require a test to occur (clicking in the Test button) before saving them, even if I'm providing a full SQL query to snapshot. I think it's because Director needs to know stuff like the data types of the columns to initialize properly the fields in the process.
The problem is that I can't stop working just because there is no VPN. I should be able to create the processes and test them later when connection to the database is restored. I can do a lot of stuff (I can even copy-paste snapshots!) but I can't change nor create new ones, and that blocks me constantly.
How can I do a snapshot save without database connection and have Director asking me the datatypes instead of trying to guess them from a "Test"?

Hi,
You can't create a snapshot without a connection to the database. A connection is needed when a snapshot definition is created in order to retrieve the column names and data types. As a solution to your problem, why not use data interfaces? Create a data interface that is of the required shape and refer to this in your processes (instead of the snapshot). You can then create mappings to different sources of data, e.g. snapshots, reference data, etc. You can test your processes when you're offline using a reference data mapping.

How to create snapshot on Oracle VM 3.1.1

Dear All,
Any one know about how to create snapshot in Oracle VM 3.1.1? Where we can find it in Oracle VM 3.1.1?
Please kindly shared experience about this.
Thanks and regards,
Vandy

Thank you very much for your help.
Now I am using Sun Storage 6180 Array direct attach (Fiber Chanel) with 2 Sun Fire X4100M2 Servers as Cluster, I don't know whether this storage can create snapshot for this or not? How about Oracle VM Manager can help for this?
It seem more difficult than VMware vSphere, if Oracle can create a option for this is very good.
Thanks and regards,

How to create a btrfs snapshot from the actual state?

Hi all,
i would like to create a backup via a snapshot from my root volume. How can i create a snapshot from the actual state of my partition and mount it again?
best regards :>

Long time ago but it could be usefull for someone else.
Create snapshot of whole disk on btrfs:
$sudo btrfsctl -s /mnt/snapshot/`date +%F` /
Delete snapshot (don't try to delete it with "btrfsctl -D", it won't work yet):
$sudo btrfs subvolume delete /mnt/snapshot/2011-06-19/
Also usefull could be to create subvolumes for snapshoting. This create testvolume directory with subvolume in /mnt.
$sudo btrfsctl -S testvolume /mnt/

CREATE SNAPSHOT command
PURPOSE:
To create a snapshot. A snapshot is a table that contains the
results of a query of one or more tables or views, often located on
a remote database.
SYNTAX:
CREATE SNAPSHOT [schema.]snapshot
[ [PCTFREE integer] [PCTUSED integer]
[INITRANS integer] [MAXTRANS integer]
[TABLESPACE tablespace]
[STORAGE storage_clause]
[ USING INDEX [ PCTFREE integer | TABLESPACE tablespace
| INITTRANS integer | MAXTRANS integer
| STORAGE storage_clause ] ...
| [CLUSTER cluster (column [, column]...)] ]
[ REFRESH [FAST | COMPLETE | FORCE] [START WITH date] [NEXT date]]
AS subquery
where:
schema
is the schema to contain the snapshot. If you omit schema, Oracle
creates the snapshot in your schema.
snapshot
is the name of the snapshot to be created.
Oracle chooses names for the table, views, and index used to
maintain the snapshot by prefixing the snapshot name. To limit
these names to 30 bytes and allow them to contain the entire
snapshot name, Oracle Corporation recommends that you limit your
snapshot names to 23 bytes.
PCTFREE
PCTUSED
INITRANS
MAXTRANS
establishes values for these parameters for the internal table
Oracle uses to maintain the snapshot's data.
TABLESPACE
specifies the tablespace in which the snapshot is to be created. If
you omit this option, Oracle creates the snapshot in the default
tablespace of the owner of the snapshot's schema.
STORAGE
establishes storage characteristics for the table Oracle uses to
maintain the snapshot's data.
USING INDEX
specifies the storage characteristics for the index on a simple
snapshot. If the USING INDEX clause not specified, the index is
create with the same tablespace and storage parameters as the
snapshot.
CLUSTER
creates the snapshot as part of the specified cluster. Since a
clustered snapshot uses the cluster's space allocation, do not use
the PCTFREE, PCTUSED, INITRANS, or MAXTRANS parameters, the
TABLESPACE option, or the STORAGE clause in conjunction with the
CLUSTER option.
REFRESH
specifies how and when Oracle automatically refreshes the snapshot:
FAST
specifies a fast refresh, or a refresh using only the
updated data stored in the snapshot log associated
with the master table.
COMPLETE
specifies a complete refresh, or a refresh that re-
executes the snapshot's query.
FORCE
specifies a fast refresh if one is possible or
complete refresh if a fast refresh is not possible.
Oracle decides whether a fast refresh is possible at
refresh time.
If you omit the FAST, COMPLETE, and FORCE options,
Oracle uses FORCE by default.
START WITH
specifies a date expression for the first automatic
refresh time.
NEXT
specifies a date expression for calculating the
interval between automatic refreshes.
Both the START WITH and NEXT values must evaluate to a time in the
future. If you omit the START WITH value, Oracle determines the
first automatic refresh time by evaluating the NEXT expression when
you create the snapshot. If you specify a START WITH value but omit
the NEXT value, Oracle refreshes the snapshot only once. If you
omit both the START WITH and NEXT values or if you omit the REFRESH
clause entirely, Oracle does not automatically refresh the snapshot.
AS subquery
specifies the snapshot query. When you create the snapshot, Oracle
executes this query and places the results in the snapshot. The
select list can contain up to 253 expressions. A snapshot query is
subject to the same restrictions as a view query.
PREREQUISITES:
To create a snapshot in your own schema, you must have CREATE
SNAPSHOT system privilege. To create a snapshot in another user's
schema, you must have CREATE ANY SNAPSHOT system privilege.
Before a snapshot can be created, the user SYS must run the SQL
script DBMSSNAP.SQL on both the database to contain the snapshot and
the database(s) containing the tables and views of the snapshot's
query. This script creates the package SNAPSHOT which contains both
public and private stored procedures used for refreshing the
snapshot and purging the snapshot log. The exact name and location
of this script may vary depending on your operating system.
When you create a snapshot, Oracle creates a table, two views, and
an index in the schema of the snapshot. Oracle uses these objects
to maintain the snapshot's data. You must have the privileges
necessary to create these objects. For information on these
privileges, see the CREATE TABLE, CREATE VIEW, and CREATE INDEX
commands.
The owner of the schema containing the snapshot must have either
space quota on the tablespace to contain the snapshot or UNLIMITED
TABLESPACE system privilege. Also, both you (the creator) and the
owner must also have the privileges necessary to issue the
snapshot's query.
To create a snapshot, you must be using Oracle with the procedural
option. To create a snapshot on a remote table or view, you must
also be using the distributed option.

Hyper-V creates hidden Snapshots - Howto merge

First of all, is there a possibility to give information about a bug to microsoft without paying?
As I haven't found one (which would be really NOT customerfriendly) and I hope to help others I will post my problem and solution here.
Today our productive server which is a vm on a hyper-v host ran out of hdd space which was quite confusing for us as the assigned size of the disk is much less then the space the physical disk on the host has.
The hyper-v manager didn't show any snapshots. In the filesystem we saw a vhd AND a avhd file, the avhd file being the newer one and causing the error as it took all the space left on the disk.
We do NOT know where this avhd file comes from (maybe microsoft or some of you know how this could have happened?) but here comes the solution how I managed to merge the vhd and the avhd file.
I created another snapshot. So now I had two avhd files and one vhd file. Now I also saw at least the LAST snapshot in the hyper-v manager. I deleted this last snapshot in the hyper-v-manager (DO NOT DELETE THE AVHD FILE IN THE FILESYSTEM!) and started merging
the snapshot and the vhd. In this merging process also the hidden snapshot is merged and both avhd files dissappear and diskspace is free again.
Reserve some time for the merging process - it took me about one hour.
I'm quite alarmed about that now as we are just bying a new server and wanted to use hyper-v again. Would be really helpful to know where this hidden snapshots come from and how to avoid them so we can decide if we should stick to our decision to use hyper-v.
Also I feel very unhappy with the fact that there iseems to be no possibility to contact microsoft without paying even if there seems to be a bug in their OS.
Best regards,
Tina

Hi Tina, There are a few possibilities here. The Virtual Server could have been moved from a previous Version of Hyper-v, leaving the AVHD file inplace, this wouldn't show up in the new hyper-V console.
Or some backup solutions create independent snapshots, which are using to backup online Virtual servers
Have you moved your Virtual Servers recently to new hardware ? you don't mention what version of Server your are using 2012 ? 2008R2 , 2012R2 ?.
Also if you delete a snapshot on 2008R2, the snapshot can stay there until you power off the virtual server. at which point it then automatically merges back into the original VHD.
When you delete a snapshot, the .avhd files that store the snapshot data remain in the storage location until the virtual machine is shut down, turned off, or put into a saved state. As a result, when you delete a snapshot, you will need to put
the production virtual machine into one of those states at some point to be able to complete the safe removal of the snapshot.

How to Create A new Database in the oracle 10g XE

i have oracle 10g XE i tried to create a new database but its giveing me error when i execute the sql command that is create database testDatabase how to create a new database in oracle 10g XE

Hi there 785434,
(This is a generic SQL question relating to Database Triggers, please post future questions of this type into the relevant forum area.)
Moderator, please move this if able
I use Before Update and Before Delete Triggers to record a 'snapshot' of the row being changed in my applications.
Example:
CREATE TABLE TEST
DATA VARCHAR2(64 CHAR),
CREATING_USERID VARCHAR2(20 CHAR) DEFAULT user NOT NULL,
CREATED_DATE DATE NOT NULL,
CHANGED_BY_USERID VARCHAR2(20 CHAR),
CHANGED_DATE DATE
LOGGING
STORAGE
(MAXEXTENTS UNLIMITED);
CREATE TABLE TEST_HISTORY
DATA VARCHAR2(64 CHAR),
CREATING_USERID VARCHAR2(20 CHAR) DEFAULT user NOT NULL,
CREATED_DATE DATE NOT NULL,
CHANGED_BY_USERID VARCHAR2(20 CHAR),
CHANGED_DATE DATE,
CHANGE_DESCRIPTION
NOLOGGING
STORAGE
(MAXEXTENTS UNLIMITED);
CREATE OR REPLACE TRIGGER TRG_BU_TEST
BEFORE UPDATE ON TEST FOR EACH ROW
BEGIN
INSERT /*+ append */ INTO TEST_HISTORY
(DATA, CREATING_USERID, CREATED_DATE, CHANGED_BY_USERID, CHANGED_DATE, CHANGE_DESCRIPTION)
VALUES
(:old.DATA, :old.CREATING_USERID, :old.CREATED_DATE, USER, SYSDATE, 'UPDATE');
END;
CREATE OR REPLACE TRIGGER TRG_BD_TEST
BEFORE DELETE ON TEST FOR EACH ROW
BEGIN
INSERT /*+ append */ INTO TEST_HISTORY
(DATA, CREATING_USERID, CREATED_DATE, CHANGED_BY_USERID, CHANGED_DATE, CHANGE_DESCRIPTION)
VALUES
(:old.DATA, :old.CREATING_USERID, :old.CREATED_DATE, USER, SYSDATE, 'DELETE');
END;
Using triggers like this will record who made an update or delete to the database and record the row before it was changed.
Note that this method might not be suitable for very high transaction rates.
You will need to 'clear' these history tables as part of routine maintenance.
Hope that this Helps.
Ronald.

How to create a single report using 5 difftent reports

Hi Experts
how to create a single report using 5 repors in it.
Example
I have to create a Survey history report using
Reports like Surevy 1
                  Surevy 2
                  Surevy 3
                  Surevy 4
                  Surevy 5
Please suggest me.
Santosh

Use Analysis Process Designer (RSANWB) to feed each of the survey BEX reports to one DSO. Assuming each of the surveys has something in common to compare. Could also be used as a snapshot storage for the surveys in case history needs to be compared/archived.
Build the Direct update DSO with the survey objects. Add needed time characteristics and/or version control objects to the key.
Data sources will be the 5 surveys.
Add formula to hardcode version/time for history.
Data target is the direct update DSO.

How to create a 'Previous History' brush tool along with content aware

Truly did not know how to create a good title here.
When you use the 'Content Aware' tool and move subject 'A' to point B what happens is that A now sits on top of B which in turn means part of the image within B may be missing and you may still want it there where it was and where it should be. You could use the 'history brush' tool to brush away part of the new insert and erase what is there to reveveal what was there. How do you do the same thing to image A which now sits on B (to reveal what was there on A originally). What I mean is this. I moved a person from point A to point B. but parts of this person are missing (his ear, his knee, his shoe) so how do I get those parts back (in the new location)?
The history brush tool appears to be erasing by subtracting, what I would like to do in this case of course is not subtract but add or 're-add'.
Thank you

Hello,
here's a possible solution, before using content aware, take a snapshot of A and B, then use it as your history brush source whenever you need to 're-add':
please post back if you have any questions

How to create an "overlay" in Advanced Grid in Flex?

I'd like to know how to create an "overlay" in Advanced Grid in Flex? See the snapshot of what I'm trying to achieve here:

As you can see that changing selected item's background won't be enough for achieving the same result because elected row is slightly higher than other rows.

Maybe something like this?

How to create a new database instance from an existing one?

Hi, I basically want to create a snapshot of a production
instance (version 8.1.7) for querying purposes. Would anyone
tell me the steps involved? What I did as follows:
1. Copy all data files to a new location
2. Modify init.ora accordingly. I believe there is no separate
control file for this version.
But when I startup the instance, got this error:
ORA-01103: database name 'TRITON' in controlfile is not 'HERCULE'
What is missing? Do these data files contains links to the
previous instance name?
Thanks for any help.

Hi All,
I need some help in recreating new database instance.
Here are the steps I have done so far:
1. Created a database with name 'LASTDB' using DBCA
2. Connected to RMAN.
3. RMAN>SET DBID=******; (of the source database)
4. Connect to target. RMAN>connect target SYS/*****;
5. Executed controlfile restore on RMAN.
RMAN>Run{
Allocate channel D1 Type DISK;
Set controlfile autobackup format for device type DISK to
\\<ip_address>\Backup\Prod\%F;
Restore controlfile from autobackup;
6. RMAN> ALTER DATABASE MOUNT;
Now got an error saying ORA-01103: database name PRODDB' in control file is not LASTDB
I tried using NID to change the database name but it's throwing an error that database is not mounted.
I have browsed a lot and found that I need to recreate a control file of the production database using ALTER DATABASE BACKUP CONTROLFILE TO TRACE and should edit the trace file. But it also says to shutdown the source database which is production database and I cannot try that.
Also I have tried adding a line to init.ora like lock_space_name = LASTDB. Also tried replacing everything from LASTDB to PRODDB but that didn't work either.
I have been trying to find a solution to this. Please bear with me as I'm a beginner and please let me know how I can fix the error.
I am running oracle 10.1.0.2.0 enterprise edition on windows 2000.
Thanks for your patience,

How to create Database, table , and apply triiger on oracle10g lite ?

Hello All,
I want to use oracle 10g lite , i just download oracle 10g lite from oracle site and just install on my system, i have no any knowledge how to create database, how to create tables and how to apply triggers on tables. I want to access this database using JDBC.
plzzzzzzzzzzzzzzzzzz help me...............
Thanks in advance
Pankaj

are you trying to use oracle lite just as a database? it is normally used as part of a data synchronisation from a server, replicating snapshots to create the database and tables on the client.
PL/SQL format triggers are not supported in the oracle lite client. Java stored procedures are, but you would need to build the table interactions

Reviewing steps to create a snapshot

I am sure this is dead simple, but I cannot see how to do it.
I have just editted an image, initially by cropping, then making some general tweaks. I saved this as a Snapshot.
After some though, I decided I wanted to change the crop, so I went back to the original image, and re-cropped it. Fine, But now I wanted to re-apply some of the changes made in the Snapshot. How can I see the steps that I went through to create the snapshot? I saw Update with Current Settings on the sub-menu (right click) for the snapshot, but wasn't sure if that was what i wanted to do.
Can someone point me in the right direction pls.
Thanks

Thanks for your quick responses. What I didn't make clear in my questions was this... When I say I wanted to re-crop, I want to re-crop the original image to include a part that is not in the cropped image. Not so much include more in the crop, just re-position it. That is why I went back to the original image, as this looked to be the only way to see all of the original image.
Sorry to have not made that clear in the first place.
I guess a more ideal solution would be able to adjust a crop on a snapshot, and by adjust I mean increase, decrease, or re--position the crop.
Anyway, I think therefore, the question I should have asked is this. Having created a Snapshot, how can I reload this, so I can continue my workflow from where that snapshot finished? (This would enable me to see the steps to reach that snapshot).
