3. DST issue with APM 9.5.0, 9.5.1, 9.5.2 - Oracle Partition Creation Failed Message received after Daylight Savings Time change ORA-14074 TEC607559
While running APM 9.5.0, 9.5.1 or 9.5.2 with an Oracle APM Database, the following (or similar) errors in the APM CE GUI and in TIM Collection Service EM Logs may occur when transitioning to/from Daylight Saving Time:
• Partition creation failed
• Administration Enterprise Manager 0.0.0.0 Partition creation failed.
• Disk or oracle table space probably exhausted.
•Manager.com.timestock.tess.util.DbUtils] Execute failed for SQL DDL 'ALTER
TABLE ts_us_sessions_map ADD PARTITION ts_us_sessions_map_20140309_03
VALUES LESS THAN (TIMESTAMP '2014-03-09 4:00:00 -4:00')'
java.sql.SQLException: ORA-14074: partition bound must collate higher than that of the last partition"
This indicates that last table partitions for table ‘ts_us_sessions_map’ overlaps with new partition and prevents its creation.

12. How to implement CA EEM and LDAP for Authentication and Authorization of CA APM TEC593939
Using CA EEM, CA Embedded Entitlements Manager, in conjunction with a supported LDAP Server, it is possible to eliminate manual updates to CA APM configuration files every time you need to add a new user, change a password or update access permissions.
CA EEM allows you to utilize a supported LDAP server for authentication while it controls authorization policies for LDAP users and groups. If you do not use LDAP, EEM can even perform authentication duties using the secure, proprietary CA Directory, which is included.
CA EEM is bundled with CA APM and is available from the APM Product Downloads Page on support.ca.com. It can be installed on the same or a separate server as the Enterprise Manager.. CA EEM supports many CA products, serving as a single point of control for authentication and authorization.

The CEM Transaction Impact Monitor (TIM) is a passive network probe that collects business transaction information on HTTP/HTTPS traffic through a network span or tap. The CEM TIM is a C++ based application that runs on specific versions of the Linux operating system and does not use the Bash shell for any of its operational functions, however prior to version 9.6, the TIM installation script does use the bash shell.
It has been recently disclosed by industry experts that most versions of Unix, Linux, OSX and other variants are susceptible to a security issue that allows the execution of bash code injection. This is being referred to in the media as "Shellshock".
