Problem summary
**************************************************************** * USERS AFFECTED: All DB2 10 for z/OS utility users reading * * from, or writing to, a DFSMS managed and * * compressed dataset and specifying BUFNO= * * on the DD card * **************************************************************** * PROBLEM DESCRIPTION: UNLOAD, specifying an SMS-managed * * compressed SYSREC along with BUFNO= on * * the DD card results in an ABEND0C1 RC1 * * at IGG019VX +x'04A8' * * * * LOAD, utilizing an SMS-managed * * compressed SYSREC along with BUFNO= on * * the DD card results in either a hang of * * the utility or the utility abends with * * ABEND04E RC00E40071 at DSNUGSDA * * +X'584C' * **************************************************************** * RECOMMENDATION: Apply corrective PTF when available * **************************************************************** Both of the LOAD and UNLOAD errors were the result of specifying BUFNO=2 on the SYSREC DD card when the data set was DFSMS managed and compressed. This resulted in only 2 buffers being allocated when the data set was opened. However, utility processing later changed that value by specifying that 4 buffers were to be used. For UNLOAD, this caused z/OS code to abend with an ABENDS0C1 RC00000001 (user buffer mismatch error) from IGG019VX OFFSET04A8. For LOAD, one of two problems could occur: 1. If the SYSREC data set contained a small number of rows, MSGDSNU032I (ERROR ON WORKFILE) and MSGDSNU040I (ERROR ACCESSING DDNAME SYSREC) were issued and then LOAD abended with ABEND04E RC00E40071. 2. If the SYSREC data set contained a large number of rows, the utility would hang. ADDITIONAL KEYWORDS: DSNU032I DSNU040I
Problem conclusion
Code has been changed to not reset the number of buffers to use when BUFNO has been specified and the data set is compressed and SMS managed.
