Should I monitor the MGMTDB database?

During the installation of Oracle Grid Infrastructure 12.1.0.1 you had the option to install the Grid Infrastructure Management Repository (GIMR) database MGMTDB. With 12.1.0.2, that option went away, and the MGMTDB database became mandatory. Given that it’s a database, the question of whether it should be monitored by Enterprise Manager was raised by a number of customers, and unfortunately a variety of different answers were forthcoming from different sources in Oracle.

Before we clarify that confusion, let’s have a look at what the MGMTDB database is used for. The best place to look for that is, of course, the documentation, but let me quote it here for the sake of clarity:

The Oracle Grid Infrastructure Management Repository:

Must See Session at This Year’s OOW

I’ve seen a lot of interesting posts about what’s going to be presented next week at OOW15, and I’ve blogged about those specific to Enterprise Manager previously – see the links Private Cloud and DBLM, Database Manageability and Middleware Management for more detail. But some people have come to me and said “There are so many sessions to go to for Oracle Open World, can you identify the must see session for what’s happening with Enterprise Manager?”

Oracle Open World and Oak Table World Schedule!

So I’ll be heading out for Oracle Open World 2015 in just over another week.

OOW2015 Middleware Management

This posting covers the Middleware Management sessions at OOW2015. Note that these are middleware management via Enterprise Manager, as opposed to sessions specifically covering middleware features and functions. Also, I have not duplicated here sessions I have already documented under Oracle Management Cloud or Private Cloud / DBLM, so please visit those posts for sessions that fall under both categories. The following sessions fall under this category:

OOW2015 Database Manageability

This posting covers the Database Manageability sessions at OOW2015. Note that these are database manageability via Enterprise Manager, as opposed to sessions specifically covering database features and functions. The following sessions fall under this category:

OOW2015 Private Cloud and DBLM

Yesterday I posted an entry on what was coming with OOW2015, specifically discussing the Oracle Management Cloud sessions. This post is similar but looking at one of the more “traditional” EM areas that my team is responsible for – Private Cloud and DBLM. The sessions that are of most interest here are:

OOW2015 is almost here!

Hard as it is to believe, yet again it is time for the biggest Oracle conference on the planet (or any other planet for that matter!) Yes, OOW2015 is just around the corner! Unfortunately I won’t be there this year, as I have my eldest daughter’s wedding shortly after it, but nevertheless having seen what’s coming up from the Enterprise Manager side of the house, there are a few sessions I can certainly recommend.

BI Publisher Tips and Techniques

A colleague of mine asked recently if we had any best practices for BI Publisher, the latest and greatest reporting tool we use within Enterprise Manager (the old tool, Information Publisher, is of course also still supported but this post is relevant to BI Publisher). As you would well know if you’ve been following my posts or heard me presenting at conferences, best practices is a term I hate, so rather than using that term let’s discuss some tips and techniques that might be relevant to you when using BI Publisher.

Tip #1: Allocate Extra Memory

The amount of required memory for BI Publisher depends on a huge number of factors – complexity of reports, size of datasets being returned, BI Publisher scheduling load, etc. We recommend adding at least 1.5 Gb of RAM for the OMS machine, but you may need as much as 4-5 Gb depending on the factors just mentioned.

Recommendations to Address Cloud Performance Issues via EM12c

So I’m going to start this post with an admission-  I don’t have access to a cloud environment to test this out, but I know what I would do first if I experienced slow response time on database creation or cloning via EM12c to the cloud and I would like to at LEAST post what I would do to give others the chance to test it out and see

Cloud Control 12.1.0.5 : It’s production upgrade day…

cloudI mentioned a couple of months ago I was planning to upgrade our production Enterprise Manager Cloud Control installation from 12.1.0.4 to 12.1.0.5. Well, today was the day. I held back a while because I knew I would be out of the country for a while on the Latin America tour and I didn’t want to make a big change before I ran away. :)
