Introspection on Vault Cache Setup
File Introspection on Vault Cache setup is exactly same as on any
other normal setup.
Also, for the file introspection to run on the Vault Cache setup just
make sure that the below variable is added in the
VaultServer.properties file on the Vault Server in a Vault Cache
Setup.
VaultServer_VSForWCV = true
The Complete Mechanism of File Introspection on Vault Cache can be
explained with below points:
- User create a document and checking a CATPart in it and saves
the same in DB.
- The vault client writes the document in the local vault cache.
- The vault cache sends a lock reservation to the remote vault
server with the vault cache name (as seen by the vault client, the
document is reserved for writing but is still available in read
mode).
- After save , the Process of File Introspection is triggered on
the LCA server and file Introspection gets started on LCA server.
- After File Introspection completes cgrs,jpegs and etc gets
created in LCA server /tmp and are transferred to Cache Server Vault
and also the Lock reservation is sent to the remote Vault (as seen
by the vault client, the generated cgr, jpeg etc is reserved for
writing but is still available in read mode).
- Also, Local Vault Cache gets updated with cgr, jpeg and etc
created after File Introspection.
- The vault server is informed in which vault cache the documents
i.e. Document , cgr, jpeg etc are saved.
- The vault server will retrieve the document through an
asynchronous replication process and hence Vault Server gets updated
with the documents, cgr, jpegs and etc.
- The Retrieve/Refresh between Vault Server and Vault Cache will
occur after every 300 second by default also you can vary this time
as per your requirement using variable.
- Also, once saved on the Vault Server , the document, cgr, jpeg
etc can then be read and saved again by vault clients.
