12.2.0.1

Is “imp” still supported in Oracle Database 12.2?

exp imp

Good question we receive quite often:

Is “imp” still supported in Oracle Database 12.2?

For clarification: I don’t talk about “impdp” but about old “imp” (import). And yes, it is still supported in Oracle 12.2.

The oldexp” got desupported with Oracle Database 11.1.0.6 – but “imp” is still supported, even in Oracle Database 12.2.0.x. You should be able to import your old dumps into the newest release of the database and migrate even VERY old releases directly to Oracle Database 12.2.

Actually, the biggest step upwards we’ve heard about a year …

Oracle 12.2.0.1 Bundle Patch 12.2.0.1.170516 DBBP on Linux x86-64 is available [not anymore]

All credits go to Ricardo Maeda as I knew that we’ll release a Bundle Patch for Oracle 12.2.0.1 sometime this week – but I couldn’t find it linked from the usual MOS notes. And please don’t ask my why that is.

Anyhow, with patch 2579308 you’ll get access to the first BP for Oracle Database 12.2.0.1. There will be a first bigger Proactive Bundle Patch in July at the usual schedule – but this one is at least a start.

Plus in addition get the OPatch version 12.2.0.1.7 via patch 6880880.

The BP contains:

12.2.0.1.170516BP

GIMR DB in Oracle Database 12.2

I did blog in the past already about the Grid Infrastructure Management Repository Database (GIMR DB):

SID and DBNAME are kept the same in Oracle Database 12.2. But there are a few changes and additions in Oracle Database 12.2.0.1.

GIMR DB in its own Disk Group

During a fresh installation of Oracle Grid Infrastructure 12.2.0.1 you’ll have the chance to create a disk group for GIMR DB:

GIMR DB in Oracle Database 12.2

GIMR DB – Gets its own disk group in Oracle 12.2

But you can migrate GIMR DB into a separate disk …

PGA_AGGREGATE_LIMIT enforces default since Oracle Database 12.2.0.1

The init.ora/spfile parameter PGA_AGGREGATE_LIMIT got introduced in Oracle Database 12.1.0.1.

As per documentation in Oracle Database 12.1 it got defined as:

PGA_AGGREGATE_LIMIT specifies a limit on the aggregate PGA memory consumed by the instance.“.

Furthermore the algorithm for its setting got described as:

By default, PGA_AGGREGATE_LIMIT is set to the greater of 2 GB, 200% of PGA_AGGREGATE_TARGET, and 3 MB times the PROCESSES parameter. It will be set below 200% of PGA_AGGREGATE_TARGET if it is larger than 90% of the physical memory size minus the total SGA size, but not below 100% of PGA_AGGREGATE_TARGET.”

Is your APEX version certified with your Database release?

+++ Blog post updated on Oct 2, 2019 +++ New additions marked in Red +++

+++ Blog post updated on Aug 3, 2021 +++ New additions marked in Blue +++

Last week I’ve had an interesting discussion with a customer about the certification of APEX and Oracle Database 12.2.0.1.

I did a bit of research and emailing – and thanks to the APEX team – this is the source of truth for APEX certifications.

Is your APEX version certified with your Database release?

Minimum Database version for APEX

See MOS Note:1344948.1: Application Express (APEX) Database and Web Server Certification Reference:

  • For APEX 4.0, the minimum database version is 10.2.0.3

What happens to PASSWORD_VERSIONS during an upgrade to Oracle 12.2?

I did blog a day ago about ORA-1017 connection issues in Oracle Database 12.2 once you would like to use the deprecated init.ora/spfile parameter SEC_CASE_SENSITIVE_LOGON=FALSE:

But how can this change actually happen?

Let’s check how the PASSWORD_VERSIONS is set in a fresh Oracle Database 12.1.0.2 database with the January 2017 Proactive Bundle Patch applied to it:

SQL> select username, password_versions from dba_users order by 1;

USERNAME		       PASSWORD_VERSIONS
------------------------------ -----------------
ANONYMOUS
APPQOSSYS		       10G 11G 12C
AUDSYS			       10G 11G 12C
DBSNMP			       10G 11G 12C
DIP			       10G 11G 12C
GSMADMIN_INTERNAL	       10G 11G 12C

As promised – and thanks to everybody from the Database Upgrade Development Team – the new preupgrade.jar for Oracle Database 12.2 is available:
