If the symlinks do not exist then the nbu_server resource would not start or the NBU database could not be started outside of cluster control. These symlinks are created when the nbu_server resource is brough online and they are removed when the nbu_server resource is taken offline. Prior to starting the NBU database the cluster symlinks must be in place. The nbu_server resource does not need to be started. These steps can be completed by bringing the nbudg, nbu_vol and nbu_mount resources online.

In order to do this the nbudg diskgroup must be be imported and the shared disk started and /opt/VRTSnbu mounted. It is possible to start the NetBackup database which is under cluster control, outside of the cluster.

The path for the server.log in the file must also point to the shared diskĮnsure the paths within the /opt/VRTSnbu/var/global/nf file also point to the shared disk: In the bp.conf ensure the following option points to the shared disk:Ĭheck the paths in the vxdbms file point to the shared disk and the staging directory points to staging directory on the shared disk usr/openv/netbackup/bin/cluster/NBU_RSP - this file is built by the NBU install process and contains all the relevant information for the cluster such as node names, virtual ip address, monitored services etc GAB broadcasts configuration information to all cluster members LLT transports all cluster communications to all cluster nodes HAD on each node takes.

Database replication (master/slave) is very slow too.The following files are the configuration files which have clustered paths defined in them.

Some JDBC drivers load blobs in the JVM memory which can lead to memory issues.

In our experience storing blobs in a SQL database leads to a lot of problems: You can also choose to store blobs in the SQL database but we don't recommend it. See File Storage Configuration for more on the blob storage mechanism. Instead of the filesystem, you can also elect to store the blobs in Amazon S3 or in other external storage systems using the appropriate plugin. Blob Storageīy default Nuxeo stores all blobs on the filesystem in a lock-free, cluster-aware manner, based on the "Content-addressable storage" paradigm. See also these additional explanations on why VCS ensures safe hot backups.

You have no risk of having a file referenced by the SQL database that has been removed from the filesystem.

You have no risk of having a file being in the middle of an update.

You can hot backup your SQL database and then in a second step hot backup the binary store in this case data will be consistent: If you change a field type, you can just do ALTER TABLE to change the column type. Note however that this configuration is entirely optional because Quarkus will automatically use a proper (and non-changing) value if. With VCS, schema changes in Nuxeo are automatically propagated to the SQL level (columns are added as needed, and you are warned about extra unused columns). Simple Debuggingīecause data is transparently stored in SQL tables, it's very easy to have a look at them and understand exactly what is going on. Furthermore, in some cases, you don't want the people dealing with data migration to be Nuxeo developers: in this case, using plain SQL is an advantage. As a Binary Repository Manager, Artifactory completes the picture by providing you an easy, safe and secure way to consume those binaries through support for VCS repositories.

Although we provide import / export APIs in Nuxeo, they will never be as fast as bulk inserts. Today, many technologies that are consumed as pure source files are deployed as binaries (for example, PHP, Rails, Node.js, Ruby etc.). Easy Data Injectionįor big data migration you can use direct SQL injection. Easy Reportingīecause SQL data can be accessed directly, you may use any SQL reporting tool (Business Object, BIRT, Crystal Reports.) to build custom business reports on your documents data. When using VCS, you can directly access all your data in pure SQL: the schema of the database is a mapping of the XSD schemas you defined in the Nuxeo configuration. This section's sub-pages describe the architecture of Visible Content Store (VCS).
