Goal of the page

Listing the available alignment constants and alignment position errors (APE) with some comments about validity. Usual jobs should access constants via global tags. At this link it is also described t find out which tags belong to a global tag.

Database Connection Strings

In the following <abX> is release series specific and stands for e.g. 20X:

Reading

• Using Frontier (recommended): frontier://FrontierProd/CMS_COND_<abX>_ALIGNMENT
• Directly accessing database (for very rare test): oracle://cms_orcoff_prod/CMS_COND_<abX>_ALIGNMENT

Writing

• Development/preparation DB (copied to production DB once release is closed, medium expert task): oracle://cms_orcoff_prep/CMS_COND_ALIGNMENT
• Online DB (expert task within .CMS cluster!):
  • Real DB (streamed to offline production DB): oracle://cms_orcon_prod/CMS_COND_<abX>_ALIGNMENT
  • For testing (not streamed): oracle://orcon/CMS_COND_<abX>_ALIGNMENT

Most Up-to-Date Information

More up-to-date information about existing tags can always be found via the database web interface.

CMSSW_2_1_X

The tags from CMSSW_2_0_X below are still available. In addition we have the following:

Available Tags for Tracker:

Tag Constants	Tag APE	Validity	Description	Comments

Available Tags for Muon:

CMSSW_2_0_X

Available Tags for GlobalPositions:

Tag	Validity	Description	Comments
IdealGeometry	current	zero global shift and rotation for all detectors

Available Tags for Tracker:

Note: Some scenarios were produced with the TEC bug. The effect of the bug is considered to be small, so scenarios are still tolerated. TEC bug was removed starting from CMSSW_2_0_6.

Tool for object creation and upload

A python script named =create_scenarios.py= has been used to create, validate and upload the database objects for the misalignment scenarios and ideal geometry. Please note that the script has to be run in a CMSSW environment after the cmsenv command.
