Scripts can be used to take a snapshot of a Linux instance with the DB2 application. These scripts enable GC to suspend I/O updates to the DB2 database until the GC Linux guest snapshot is completed.
|
-
On a Linux virtual machine, copy the pre.sh and post.sh script files to the /etc/google/snapshots/ directory.
-
Copy the write_suspend and write_resume scripts to a location where the DB2 database can execute them (preferably to a directory under DB2 home).

Scripts can be used to take a snapshot of a VM with the MAXDB application. These scripts enable GC to suspend I/O updates to the MAXDB database until the GC Linux guest snapshot is completed.
|
-
On a Linux virtual machine, copy the pre.sh and post.sh script files to the /etc/google/snapshots/ directory.
-
Copy suspend_logwriter and resume_logwriter scripts to a location where MAXDB database can execute them (preferably to a directory under MAXDB home).

Scripts can be used to take a snapshot of a VM with the Oracle application. These scripts enable GC to suspend I/O updates to the Oracle database until the GC Linux guest snapshot is completed.
|
-
On a Linux virtual machine, copy the pre.sh and post.sh script files to the /etc/google/snapshots/ directory.
-
Copy the pre-freeze-script.sql and post-thaw-script.sql scripts to a location where the Oracle database can execute them (preferably to a directory under Oracle home).
These scripts change the entire database to backup mode.
If the virtual machine has the Oracle iDataAgent installed on it, you can also use the consistent-archivelog-backup.rman script as a sample to run archivelog backup. This script gets a consistent snapshot, all the latest archived logs, and the current control file.

Scripts can be used to take a snapshot of a VM with the Sybase application. These scripts enable GC to suspend I/O updates to the Sybase database until the GC Linux guest snapshot is completed.
|
-
On a Linux virtual machine, copy the pre.sh and post.sh script files to the /etc/google/snapshots/ directory.
-
Copy pre-freeze-script.sql and post-thaw-script.sql scripts to a location where the Sybase database can execute them (preferably to a directory under Sybase home).
These scripts execute Sybase quiesce commands that stop updates to the databases.

Scripts can be used to take a snapshot of a VM with the MySQL application. These scripts enable GC to suspend I/O updates to the MySQL database until the GC Linux guest snapshot is completed.
|
-
On a Linux virtual machine, copy the pre.sh and post.sh script files to the /etc/google/snapshots/ directory.
-
Copy the quiesce.py and unquiesce.py scripts to a location where the MySQL database can execute them (preferably to the /usr/sbin directory).
A Python script is used to quiesce and unquiesce the databases. Python and MySQL-Python modules must be installed on the client computer.

Scripts can be used to take a snapshot of a VM with the MongoDB application. These scripts enable VMware to suspend I/O updates to the MongoDB database until the GC Linux guest snapshot is completed.
|
-
On a Linux virtual machine, copy the pre.sh and post.sh script files to the /etc/google/snapshots/ directory.
-
Copy the quiesce.sh and unquiesce.sh scripts to a location where the MongoDB database can execute them (preferably to the /opt/cv_mongodb_snap directory).
A shell script is used to quiesce and unquiesce the server.
The cv_mongodb_properties file under /opt/cv_mongodb_snap must have the parameters mentioned if applicable. Logging information will be in the file /opt/cv_mongodb_snap/logfile.
