PQ34064: IMS REL6 ALLOWS 500 PCBS PER PSB. DICTIONARY ONLY ALLOWS 255

APAR status

• Closed as program error.

Error description

• ims rel6 changed the allowable number of pcbs per psb from 255
  to 500. The Data Dictionary allows only 255. This apar has been
  created to allow 500+ pcbs per psb

  * PROBLEM DESCRIPTION: DATA DICTIONARY CURRENTLY SUPPORTS      *
  *                      ONLY 255 PCBS PER PSB. IMS CURRENTLY    *
  *                      SUPPORTS 500.                           *

  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  CURRENTLY THE DATA DICTIONARY SUPPORTS THE RELATIONSHIP OF 255
  PCBS PER PSB. ALTHOUGH A USER MAY RELATE MORE THAN 255 PCBS TO
  A PSB, THE ORDERING OF PCBS WITHIN A PSB IS LIMITED TO 255.
  THIS LIMITATION IS A RESULT OF THE DICTIONARY NAMING CONVENTION
  FOR ALL CATGORIES AND SUBJECTS THAT ONLY ALLOWS OCCURRENCE
  NUMBERS RANGING FROM 000 THROUGH 255. THE OCCURRENCE NUMBER OF
  A PCB (001-255) IS USED AS ITS SEQUENCE NUMBER TO ORDER IT
  WITHIN A PSB.
  A PCB WITH THE FULL NAME OR ALIAS NAME OF 'T,P,PSBTEST,150'
  WOULD BE LISTED AS THE 150TH PCB IN THE PSB_OUT FUNCTION.
  IF THERE ARE SEVERAL PCBS USING THE SAME OCCURRENCE NUMBER,
  THEIR INDIVIDUAL PSB SEQUENCE WOULD BE DETERMINED
  ALPHABETICALLY.
  

Problem conclusion

• THE DICTIONARY NAME FORMAT FOR PCBS HAS BEEN CHANGED TO
  SUPPORT THE IMS LIMITS OF 500 PLUS PCBS PER PSB.
  IF A PCB NAME IS NOT SPECIFIED IN THE PSB, THEN THE PSB_IN
  FUNCTION CURRENTLY CREATES A DEFAULT PCB NAME USING THE RELATED
  PSB NAME. IN THE FOLLOWING EXAMPLES, THE PSB IS NAMED TESTPSB.
  THE DICTIONARY NAME FORMAT FOR PCBS WITHIN THE 1 TO 255 SEQUENCE
  RANGE WILL REMAIN THE SAME - IE., 'T,P,TESTPSB,150'.
  
  THE NAME FORMAT FOR PCBS BEYOND THE 255 LIMIT , HOWEVER, HAS
  BEEN CHANGED TO SUPPORT ORDERING THEM IN THE PROPER SEQUENCE.
  THE DEFAULT PCB FULL OR ALIAS NAME WILL INCLUDE -
  (1) A NEW USERNAME COMPOSED OF THE VALID 1-8 BYTE PSB NAME
  FOLLOWED BY A SLASH (/) AND THE PSB SEQUENCE NUMBER, AND
  (2) AN OCCURRENCE NUMBER OF 255 - IE., 'T,P,TESTPSB/300,255'.
  THIS PCB WOULD BE LISTED AS NUMBER 300 IN THE OUTPUT OF THE
  PSB_OUT FUNCTION.
  IF A PCB NAME IS SPECIFIED, THE PSB_IN FUNCTION WILL USE THAT
  NAME AS THE PCB PRIMARY NAME, BUT CREATE AN ALIAS NAME USING
  THE PSB NAME IN THE NEW FORMAT -
  IE., PRIMARY= 'T,P,MYPCB,001'  ALIAS= 'T,P,TESTPSB/300,255'.
  
  MANUALLY CREATED PCBS ORDERED BEYOND 255 SHOULD USE THE SAME
  NEW NAME FORMAT AS THE PSB_IN FUNCTION.
  IF BEYOND SEQUENCE 255 IN RELATIONSHIPS WITH MULTIPLE PSBS,
  THEY ALSO SHOULD USE THE NEW FORMAT FOR THEIR ALIAS NAMES.
  
  THE PCB DISPLAY, DBDXPC, HAS BEEN CHANGED TO ACCEPT THE LONGER
  NAME FORMAT. IT WILL BE NECESSARY TO RUN A MFSGEN FOR DBDXPC
  TO COMPLETE INSTALLATION OF THE PTF.
