Patching, Patching, Patching
(or how I will NOT apply PSUs every quarter)

Patching, Patching, Patching
(Original: https://xkcd.com/838/ )

Patching, worst way
1. Stop everything
2. In-place binaries patching
3. Database patching, "big bang" mode
4. Start everything

Patching, worst way
1. Stop everything
2. In-place binaries patching
3. Database patching, "big bang" mode
4. Start everything
Problem: you seriously need a check-up of your operational practices

Patching, better way
1. Re-install binaries, out-of-place binaries patching
2. Stop databases, one by one
3. Move to new ORACLE_HOME, patch one by one
4. Decommission old binaries

Patching, better way
1. Re-install binaries, out-of-place binaries patching
Problem: what if you have many servers/environments and patch frequently?

Patching, best way (so far)
1. Install binaries somewhere
2. Detach and patch them
3. Keep them as golden images somewhere
4. Deploy them on the servers somehow, attach them

Flexible?
YES!

What is it?

Rapid Home Provisioning is...
Usage: srvctl ... asm
Usage: srvctl ... cvu
Usage: srvctl ... database
Usage: srvctl ... diskgroup
Usage: srvctl ... exportfs
Usage: srvctl ... filesystem
Usage: srvctl ... gns
Usage: srvctl ... havip
Usage: srvctl ... home
Usage: srvctl ... instance
Usage: srvctl ... listener
Usage: srvctl ... mgmtdb
Usage: srvctl ... mgmtlsnr
Usage: srvctl ... mountfs
Usage: srvctl ... network
Usage: srvctl ... nodeapps
Usage: srvctl ... oc4j
Usage: srvctl ... rhpclient
Usage: srvctl ... rhpserver
Usage: srvctl ... scan
Usage: srvctl ... scan_listener
Usage: srvctl ... server
Usage: srvctl ... service
Usage: srvctl ... srvpool
Usage: srvctl ... vip
Usage: srvctl ... volume
grid$ srvctl -help | grep Usage: | awk '{printf ("%s %s ... %sn", $1, $2, $4)}' | sort | uniq
Something that messes my srvctl help!

Rapid Home Provisioning is...
Usage: rhpctl ... client
Usage: rhpctl ... database
Usage: rhpctl ... image
Usage: rhpctl ... role
Usage: rhpctl ... series
Usage: rhpctl ... server
Usage: rhpctl ... user
Usage: rhpctl ... workingcopy
grid$ rhpctl -help | grep Usage: | awk '{printf ("%s %s ... %sn", $1, $2, $4)}' | sort |uniq
It has its own rhpctl command too! This is how you administer it.

Rapid Home Provisioning is a tool for...
Provisioning and patching
– Oracle Homes
– other Software
Simplifying software deployment
Patching Databases (Mass patching possible)
Centralizing Golden Images
Ensuring standardization within the enterprise

Rapid Home Provisioning has mandatory requirements
Oracle Grid Infrastructure release 12.1.0.2 or upwards (use the last PSU)
ASM Cluster File System (ACFS)
Oracle Grid Infrastructure Global Naming Services (GNS)
NFS Server and HAVIP (optional*)
Lifecycle Management Pack Option (optional*)
* how optional is optional? We will see in the next episode (coming soon)

Rapid Home Provisioning has also limitations!
The main ones:
Not available on Windows
Cannot upgrade from a release to another (planned in 12.2)
Cannot provision Grid Infrastructure Homes (not yet, maybe 12.2?)
– Bug 19596245 : IMPLEMENT GRID INFRASTRUCTURE SUPPORT IN RAPID HOME PROVISIONING
Cannot provision OS Images or VMs, not in the scope of the tool

Rapid Home Provisioning - Security Roles
Several roles -> specific permissions on Working Copies and and Golden Images
But basically three composite roles:
– GH_SA : RHP Server administrator
– GH_CA : RHP Client administrator
– GH_OPER : for generic administration

Single Cluster Architecture
(or when you have only one cluster)

Conclusions
Ease of patching
Standardized installations
Free for standalone clusters
Private-Cloud ready
Nice features
Thin documentation
Pricey option for multi-clusters
No GI_HOME Provisioning
It is not free from bugs (not rock-solid)

Embrace it or live without it?
